1. INTRODUCTION

The objective of this study was to evaluate potential toxic and neurotoxic effects of the 

test substance when administered via whole-body inhalation to rats for 4 weeks on a 

5-day per week basis (minimum of 20 total exposures). In addition, a neurotoxicity 

screen used satellite animals which included assessment of functional observational 

battery (FOB), locomotor activity, and neuropathology. 

2. STUDY DESIGN

Male and female Crl:CD(SD) rats were exposed to filtered air or one of the four 

concentrations of test substance vapor as once daily 6-hour, whole-body exposures on a 

5-day per week basis for 4 consecutive weeks. The following table represents the study 

group arrangement for both Phase I (Toxicology Phase) and Phase II (Neurotoxicity 

Phase).

The total number of exposures prior to necropsy for Phase I animals was 20, and for the 

Phase II animals the total number of exposures was 19 to 23 for replicates 1 through 5, 

respectively. 

3. METHODS

3.1. EXPOSURE METHODS:

Exposures were conducted in 1000-L stainless-steel and glass whole-body exposure 

chambers. The exposure systems were operated under dynamic conditions from a 

HEPA- and charcoal-filtered air source or breathing quality in-house compressed air 

source. Air flow rate through the chamber was such that there were 12-15 air changes 

per hour. Mean chamber temperature and relative humidity were 22 ± 2°C and 30-70%, 

respectively. These parameters were monitored continuously and recorded 

approximately every 30-40 minutes throughout the exposure. Readings outside the 

average range were documented. Oxygen content of the exposure atmosphere was 

measured during the method development phase of the study, while operating at the 

above-targeted conditions, and was at least 19%. 

All animals were housed in a normal animal colony room during non-exposure hours. 

)RUHDFKGD\¶VH[posure, the animals were placed in exposure batteries, transported to the 

exposure room, exposed for the requisite duration, and returned to their home cages. 

Food and water were not available during the exposures. 

3.2. GENERAL TOXICOLOGY PHASE ± PHASE I

3.2.1. CLINICAL PATHOLOGY

Hematology and serum chemistry parameters were evaluated from all animals on the day 

of the scheduled necropsy. Animals were fasted overnight prior to blood collection. 

Blood was collected for hematology and serum chemistry evaluation via the retro-orbital 

sinus of animals anesthetized by inhalation of isoflurane. Blood was collected for 

coagulation parameters at the time of euthanasia via the vena cava of animals 

anesthetized by inhalation of isofluorane. Anticoagulants were potassium EDTA for the

3.2.3. ORGAN WEIGHTS

The following organs were weighed from all animals at the scheduled necropsy:

Adrenal glands

Brain

Epididymides

Heart

Kidneys

Liver

Lungs (prior to inflation with fixative)

Ovaries/oviducts

Spleen

Testes

Thyroid gland with parathyroids

Thyroid gland was fixed prior to weighing. Paired organs were weighed together. 

Organ-to-final-body-weight and organ-to-brain-weight ratios were calculated.

3.2.4. MICROSCOPIC EXAMINATION

Microscopic examination of routinely prepared hematoxylin-eosin stained paraffin 

sections was performed on all tissues (except brain) collected at necropsy from all 

animals in the control and 2500 ppm groups, with exceptions as indicated on the tissue 

list above. The lungs, liver, kidneys, and all gross lesions were examined from all 

animals in the low- and mid-level groups. Stained histologic sections were examined by 

light microscopy and observations were entered in the WIL Toxicology Data 

Management System (WTDMSE\WKHSDWKRORJLVW All gross necropsy observations 

were addressed. Histologic sections were of adequate size and quality for detailed 

evaluation. The number of missing tissues was negligible and did not interfere with 

detection of test substance-related histologic alterations in the study. Histopathologic 

lesions were classified using standard published terminology to the extent possible. The

4. RESULTS FOR PHASE I

4.1. SURVIVAL

All Phase I animals survived to their scheduled necropsy.

4.2. CLINICAL PATHOLOGY

4.2.1. HEMATOLOGY AND COAGULATION

There were no test substance-related alterations in hematology and coagulation 

parameters. 

4.2.2. SERUM CHEMISTRY

There were no test substance-related alterations in serum chemistry parameters.

4.3. GROSS OBSERVATIONS

Review of the gross necropsy observations revealed no observations that were considered

to be associated with exposure to the test substance.

4.4. ORGAN WEIGHTS

There were no test substance-related alterations in final body weight or organ weights. 

The mean liver weight relative to final body weight for the 2500 ppm group females was 

12.3% higher than the control group females as a consequence of the mean final body 

weight in this group being 10.7% lower than the control group females.

The 2000 ppm and 2500 ppm female mean absolute spleen weights and mean spleen

relative to brain weights were approximately 23% lower than for the control group 

females; however, all individual animal values for these dosed groups were within the 

WIL Historical Control Data range for this age and strain of rat (Version 2.8). The 

absolute spleen weight for 1 control group female was above the upper limit (mean + 2 

standard deviations of the mean) of the historical control data for 9-12 week old rats and 

the spleen weight relative to brain weight of a different control female was above the 

historical range upper limit, contributing in part to the statistical differences between the

group means. These alterations were not considered evidence of a specific test 

substance-related effect.

4.5. HISTOLOGIC CHANGES

There were no test substance-related histologic changes noted. In males exposed to 

2500 ppm, a low incidence of focal neutrophil infiltrates and squamous metaplasia was

noted in nasal level I, with none being observed in the control group males. In the 

control group females, similar changes were evident, with none being noted in the 

2500 ppm group females. Consequently, these alterations were not considered evidence 

of a specific test substance-related effect.

5. RESULTS FOR PHASE II

5.1. SURVIVAL

Male no. 3770 (2000 ppm) was found dead on study day 22 with dark red areas noted in 

the glandular stomach. Female no. 3742 (2500 ppm) was euthanized in extremis on study 

day 25 with no macroscopic findings. No histologic evaluations were conducted and the 

causes of death were not determined for these two animals.

5.2. BRAIN WEIGHTS AND MEASURES

No test substance-related or statistically significant differences between groups were 

evident.

5.3. HISTOLOGIC CHANGES

No test substance-related histologic changes were noted.

6. CONCLUSIONS

This study was designed to evaluate the potential toxic and neurotoxic effects of 

administering the test substance by whole-body inhalation to Sprague-Dawley rats for 

6 hours each day, 5 days per week for 4 weeks at exposures of 0, 1000, 1500, 2000, and 

2500 ppm.

No test substance-related effects were evident in this study.

1. ABSTRACT

The objective of this study was to demonstrate the ability of the Kinder Scientific

MotorMonitor System (Kinder Scientific, LLC, Poway, CA, USA) to detect decreases in

activity in response to haloperidol within the U.S. EPA OPPTS Guideline 870.6300

(Developmental Neurotoxicity) and the International Conference on Harmonization

(ICH) Guideline 4.1.2 (Pre- and Postnatal Development, Including Maternal Function).

Haloperidol was administered at dosage levels of 0.05, 0.1, and 0.5 mg/kg by a single

intraperitoneal injection 30 minutes prior to behavioral testing on postnatal day (PND)

13, 17, 21 or 61. Male and female Sprague-Dawley Crl:CD (SD) rats were used for

assessment of locomotor behavior with the Kinder Scientific Motor Monitor System.

Overall, haloperidol caused a dose-dependent decrease in locomotor activity (total

activity counts and ambulatory counts) for both male and female rats at PND 13, 17, 21

and 61. Habituation was noted in PND 17, 21, and 61, but not in PND 13, males and

females. The experimental design used in this study demonstrated that WIL Research

Laboratories, LLC can detect locomotor effects of haloperidol using the Kinder Scientific

Motor Monitor System, and that the results can be considered to validate methodologies

for OPPTS Guideline 870.6300 developmental neurotoxicity studies and ICH Guideline

4.1.2 pre- and postnatal development studies.

2. INTRODUCTION

The U.S. EPA guidelines (OPPTS 870.6300) for developmental neurotoxicity studies

indicate that locomotor activity testing should be performed on postnatal day (PND) 13,

17, 21 and 60 (± 2 days). Both the OPPTS 870.6300 and ICH 4.1.2 guidelines require

that neurobehavioral endpoints such as motor behavior be included with standard

toxicological indices. Validation of laboratory methodologies and demonstration of the

sensitivity of the equipment to detect test article-related changes are requirements of

these guidelines. WIL Research Laboratories, LLC chose to evaluate the use of the

Kinder Scientific MotorMonitor System to measure locomotor behavior in control and

test article-treated animals using haloperidol, which is a potent neuroleptic known to

decrease locomotor behavior.In rodent models used in behavioral assessment of motor

behavior, haloperidol impairs motor activity, decreases startle responsiveness and often

induces catalepsy (Fowler and Senvus, 1993; Patacchioli et al., 1996; Swerdlow et al.,

1998; Tada et al., 2004; Ballard et al., 2007). Specifically, at 0.1 mg/kg (s.c.),

haloperidol was able to decrease the startle magnitude in rats following acoustic

stimulation (Swerdlow et al. 1998). Regarding generalized motor behavior during open

field assessments, haloperidol at 0.05 mg/kg (i.p.) decreased activity counts, distance

traveled, and overall velocity (van den Buuse, 2003). For physically demanding

performance tasks, haloperidol at 0.16 and 0.32 mg/kg decreased the overall locomotor

speed of the rat during testing, while a dose as low as 0.04 mg/kg caused impaired task

performance (Fowler and Senyuz, 1993). Further behavioral measurements by

Patacchioli et al. (1996) showed that haloperidol at 0.5 mg/kg (i.p.) when given to

stimulated rats increased catalepsy time, while decreasing ambulations, rears, locomotor

starts, and overall activity. These findings were supported in methamphetaminestimulated rats where haloperidol induced catalepsy and decreased locomotion at dosages

ranging from 0.032 to 0.32 mg/kg (Tada et al., 2004).

3. MATERIALS AND METHODS

3.1. TEST SPECIES AND HUSBANDRY

Sprague-Dawley Crl:CD(SD) rats were obtained from Charles River Laboratories, Inc.

(Raleigh, NC, USA). Twenty females with litters (5 pups/sex) were ordered to provide

20 rats/sex/group for testing on PND 13, 17 and 21. The breeder females were

individually housed in plastic maternity cages with nesting material (Bed-O’Cobs®). The

dams and pups remained in these cages until euthanasia on lactation day/PND 21. For

the PND 61 group, 80 rats/sex for motor assessment. The animals were housed 2-3/cage

(by sex) for 1 week, then individually in suspended wire mesh cages until euthanasia.

Environmental controls were set to maintain temperature at 71 ± 5o F and relative

humidity between 30–70%. Air handling units provided a minimum of 10 fresh air

changes per hour. Fluorescent lighting, controlled by timers, provided illumination for a

12-hour (6:00 a.m. – 6:00 p.m.) light/dark photoperiod. Temperature and relative

humidity were monitored continuously. Reverse osmosis-purified water and PMI

Nutrition International, LLC Certified Rodent LabDiet® 5002 were offered ad libitum

during the course of the study.

3.2. TEST MATERIAL AND PREPARATION

Haloperidol was purchased from Sigma Aldrich, Inc., St.Louis, MO, USA. An

appropriate amount of haloperidol was mixed with the vehicle (1% lactic acid) to produce

dosing levels of 0.05, 0.1 and 0.5 mg/kg of body weight with a corresponding dosage

volume of 10 mL/kg (for PND 13, 17 and 21 neonates) and 1 mL/kg (for PND 61 young

adults) Dosing solutions, including the vehicle for administration to the control group,

were prepared on each day of dose administration.

3.3. EXPERIMENTAL DESIGN

For the neonatal phase, four groups of 20 rats/sex received an intraperitoneal injection of

0, 0.05, 0.1 or 0.5 mg/kg haloperidol on PND 13, 17 and 21. For the young adult phase,

the same dosages of haloperidol were administered to four groups of 20 rats/sex on

PND 61. At all four ages, the haloperidol was administered 30 minutes prior to

assessment of locomotor behavior. All rats were observed twice daily for moribundity

and mortality, once in the morning and once in the afternoon until euthanasia. Body

weight and clinical observations were recorded on each day of dose administration. The

observations included, but were not limited to, evaluations for changes in appearance of

skin and fur, eyes, mucous membranes, respiratory and circulatory systems, autonomic

and central nervous systems, somatomotor activity and behavior. Additional

observations, if needed, were documented in the study records. The following table

3.4. BEHAVIORAL TESTING

Twenty neonatal animals/sex/group were assigned to the locomotor activity tests

performed on PND 13, 17, 21, and 20 young adult animals/sex/group were assigned to

the locomotor activity test performed on PND 61 using the automated Kinder Scientific

MotorMonitor System (Kinder Scientific, LLC, Poway, CA, USA). The test session was

in a sound-attenuated room and was 60 minutes in duration, consisting of 6 subintervals

lasting 10 minutes each. Locomotor activity was evaluated as total and ambulatory

activity counts obtained over each subinterval (0-10 minutes, 11-20 minutes, 21-30

minutes, 31-40 minutes, 41-50 minutes and 51-60 minutes) and the entire 60-minute

session.

3.5. STATISTICAL ANALYSIS

All analyses were two-tailed for minimum significance levels of 5% and 1%. All

statistical tests were performed by a computer with appropriate programming as

referenced below. Total and ambulatory locomotor activity counts were analyzed, by sex

and session, with a repeated measure analysis of variance (RANOVA). Factors in the

model included treatment group (TRT), time interval (TIME), and the interaction of time

interval and treatment group (TRT*TIME). The SAS® procedure PROC MIXED was

used for analysis with the random effect of animal included as the repeated measurement.

The covariance structure across time was selected by comparing Akaike's Information

Criterion.

The monotonic dose-response relationship was evaluated using sequential linear trend

tests based on ordinal spacing of dose levels. The linear dose by time interaction was

evaluated and, if significant at the 0.05 level, trend tests on treatment means were

performed at the 0.05 level for each time interval. If the linear dose by time interaction

was not significant, the trend test was conducted across the pooled time intervals of the

entire session only.

Nonmonotonic dose responses were evaluated whenever no significant linear trends were

detected but TRT and/or TRT*TIME interaction was significant at the 0.01 level. Within

the framework of the RANOVA, pairwise comparisons were made for each individual

test article-treated group with the control group through linear contrasts. If TRT*TIME

was significant, the comparisons were conducted for each time interval. If only the TRT

effect was significant, the comparisons were conducted across the pooled time intervals

of the entire session. These nonmonotonic dose-response comparisons were conducted at

the 0.01 significance level.

All statistical analyses were conducted by BioSTAT Consultants, Inc., Portage, MI, USA,

using SAS Version 8.2 (SAS Institute, Inc., 1999-2001) software.

4. RESULTS AND DISCUSSION

A normal ontogenic profile of activity in control animals was demonstrated by the Kinder

Scientific MotorMonitor System when examining both the mean total and mean

ambulatory activity counts from PND 13, 17, and 21 males (Figures 1A and 2A). This

trend, however, was not present in females (Figures 1B and 2B) because of the elevated

level of activity in the PND 13 control females. Specifically, the PND 13 vehicle control

males tended to be less active than the PND 17 males in the same group, with activity

decreasing on PND 21. This is consistent with the development of motor behavior in a

novel environment, where activity is relatively low in PND 13 neonatal rats, increases

around PND 17 and then decreases around PND 21. Total activity counts measured in

each subinterval by the Kinder Scientific MotorMonitor in PND 13 haloperidol treatment

groups (Figure 3A and B) shows a decreased motor activity for males (0.5 mg/kg) and

females (0.05, 0.1, and 0.5 mg/kg). This same haloperidol effect was also present in

ambulatory activity counts over the subintervals (Figure 4A and B), where ambulatory

activity was decreased in males (0.5 mg/kg) and females (0.05, 0.1, and 0.5 mg/kg).

When examining the mean total and ambulatory activity taken over all subintervals

(Figure 1A and B, Figure 2A and B), there was also an indication that the PND 13

females showed a dose-dependent decrease in activity for each haloperidol treatment,

whereas PND 13 males only showed decreased motor activity at 0.5 mg/kg. In the PND

13 males, the lower haloperidol doses (0.05 and 0.1 mg/kg) did not consistently decrease

motor activity. Although the decreased motor activity following haloperidol treatment

was attenuated in males, the decreased total and ambulatory activity counts are consistent

with previously published studies indicating that haloperidol decreases overall motor

activity (Fowler and Senyuz, 1993; Patacchioli et al., 1996; Swerdlow et al., 1998; Tada

et al., 2004; Ballard et al., 2007).

The total activity counts across individual subintervals measured in PND 17 males and

females (Figure 5A and B) showed a more robust dose-dependent decrease than in the

PND 13 haloperidol treatment groups (0.05, 0.1, and 0.5 mg/kg). In a similar manner, the

PND 17 male and female (Figure 6A and B) ambulatory activity counts followed the

same dose-dependent trend following haloperidol treatment at 0.05, 0.1, and 0.5 mg/kg.

For both total and ambulatory activity, the presence of a dose-dependent decrease in the

PND 17 males was partially the result of the relatively large increase (approximately 3-

fold) in the baseline (vehicle control) activity compared to the vehicle control group on

PND 13. In addition, there was the presence of habituation over the course of the

behavioral assessment in the vehicle control males and females on PND 17. When

examining the mean total and ambulatory activity taken over all subintervals (Figure 1A

and B, Figure 2A and B), there was also an indication that the PND 17 males and females

showed the same dose-dependent decrease in activity with haloperidol treatment. This is

consistent with the effects of various doses of haloperidol (0.03 mg/kg to 0.5 mg/kg)

decreasing overall and ambulatory activity, while increasing catalepsy in male and female

rats (Fowler and Senyuz, 1993; Patacchioli et al., 1996; Swerdlow et al., 1998; Tada et

al., 2004; Ballard et al., 2007).

This effect of haloperidol decreasing total activity counts over the six subintervals was

also present in the PND 21 male and female 0.1 and 0.5 mg/kg treatment groups

(Figure 7A and B). Ambulatory activity taken over the six subintervals also decreased in

a dose-dependent manner for both males and females (Figure 8A and B). In the PND 21

males and females, habituation to the environment was present in controls, as well as in

the 0.01, 0.1, 0.5 mg/kg haloperidol treatment groups, although the habituation profile

was difficult to evaluate for males and females in the 0.5 mg/kg group. The decreased

motor behavior (total and ambulatory activity counts) was similar to the overall trend

noted in PND 17 males and females, as well as the effect of haloperidol decreasing motor

activity indicated in the literature. This is also consistent with the effects of various doses

of haloperidol (0.03 mg/kg to 0.5 mg/kg) decreasing overall and ambulatory activity,

while increasing catalepsy in male and female rats (Fowler and Senyuz, 1993; Patacchioli

et al., 1996; Swerdlow et al., 1998; Tada et al., 2004; Ballard et al., 2007).

In general for the PND 13 males and females, habituation did not occur over the course

of assessment for both total and ambulatory activity (Figure 3A and B, Figure 4A and B).

There was also an apparent gender effect in both total and ambulatory activity counts

taken over the individual subinterval or over the entire assessment period suggesting that

females are more sensitive to haloperidol treatment than males. This apparently

attenuated effect, however, is likely due to elevated baseline (vehicle control) activity

measurements in females compared to males at PND 13. As previously noted, the PND

13 rats did not have an habituation profile, whereas this profile became present in the

PND 17 and 21 rats (Figures 5 through 8). This indicates that the Kinder Scientific

MotorMonitor System was able to detect the development of activity for PND 13, 17 and

21 males and females.

Haloperidol treatment of male and female PND 61 young adults (Figure 10A and B)

identified a decrease in total activity over the course of the six subintervals only at the

two higher doses (0.1 and 0.5 mg/kg). This same dose effect of 0.1 and 0.5 mg/kg

haloperidol was also present in the ambulatory activity data over all subintervals (Figure

11A and B). Although habituation was present in the control and haloperidol treatments

(0.05, 0.1, and 0.5 mg/kg), the 0.5 mg/kg profile was attenuated. Since trend of

habituation was specific within all PND 61 rats, this was likely indicative of a decreased

sensitivity in the young adult rats (or increased sensitivity in younger rats). This was also

apparent in the mean total and ambulatory activity counts for the entire testing session

(Figure 9A and B) where only the 0.1 mg/kg and 0.5 mg/kg doses substantially decreased

activity. However, haloperidol still decreased motor activity (total and ambulatory

activity counts) in both males and females, which is consistent with the previously

examined ages in this study and with the published literature (Fowler and Senyuz, 1993;

Patacchioli et al., 1996; Swerdlow et al., 1998; Tada et al., 2004; Ballard et al., 2007).

In conclusion, the motor activity data (i.e. total activity and ambulatory activity) for

Sprague Dawley Crl:CD (SD) rats generated by the Kinder Scientific MotorMonitor

System are consistent with the effects of haloperidol on motor behavior. This motor

monitoring system is therefore capable and sensitive enough to measure reductions in

motor activity in neonatal and young adult rodents with a positive control agent such as

haloperidol.

1. ABSTRACT

The objective of this study was to demonstrate the ability of the Kinder Scientific

MotorMonitor System to detect increases in activity in response to nicotine and

amphetamine within the U.S. EPA OPPTS 870.6300 (Developmental Neurotoxicity),

OECD 426 (Developmental Neurotoxicity) and ICH 4.1.2 (Pre- and Postnatal

Development) guidelines. Nicotine and amphetamine were administered to male and

female Sprague-Dawley Crl:CD rats 3 and 15 minutes, respectively, prior to assessment

of locomotor behavior with the Kinder Scientific MotorMonitor System. Nicotine was

administered at a dosage level of 0.1 or 0.5 mg/kg by a single intraperitoneal injection to

neonatal rats on postnatal days (PND) 13, 17 and 21. Amphetamine was administered at

a dosage level of 1 or 3 mg/kg by a single intraperitoneal injection to young adult rats

(male and female) on PND 61 and at a dosage level of 0.2 or 1 mg/kg to young adult

PND 61 females. Nicotine caused an increase in locomotor activity (mean total and

ambulatory activity) in male and female neonatal rats at PND 13, 17 and 21. The

habituation profile was evident in the PND 17 and 21 males and females. In a similar

manner, amphetamine stimulated locomotor behavior in male and female rats at PND 61,

causing both total and ambulatory activity to increase. The subsequent female-only

groups (0.2 and 1 mg/kg amphetamine) exhibited a dose response with increased total

and ambulatory activity compared to controls. In the PND 61 males and females (given 1

or 3 mg/kg amphetamine), the habituation profile was only present in the control and

3 mg/kg amphetamine treatment groups, whereas the habituation profile was present in

the female-only PND 61 control and 0.2 mg/kg amphetamine groups. The experimental

design used in this study demonstrated that WIL Research can detect locomotor effects of

nicotine and amphetamine using the Kinder Scientific MotorMonitor System, and that the

results can be considered to validate methodologies for OPPTS 870.6300 and OECD 426

developmental neurotoxicity studies and ICH 4.1.2 pre- and postnatal development

studies.

2. INTRODUCTION

The U.S. EPA Guideline OPPTS 870.6300 and OECD Guideline 426 for developmental

neurotoxicity studies indicate that locomotor activity testing should be performed on

postnatal (PND) 13, 17, 21 and 60 (± 2 days). The guidelines, and also ICH 4.1.2 require

that neurobehavioral endpoints such as motor behavior be included with standard

toxicological indices to support product registration under the Federal Insecticide,

Fungicide and Rodenticide Act (FIFRA) and the Toxic Substances Control Act (TSCA).

Validation of laboratory methodologies and demonstration of the sensitivity of the

equipment to detect test article-related changes are requirements of this guideline. WIL

Research Laboratories, LLC chose to evaluate the use of the Kinder Scientific

MotorMonitor System to measure locomotor behavior in control and test article-treated

animals using nicotine and amphetamine, which are known to increase indices of

locomotor behavior.

Both nicotine and amphetamine are widely used in the rodent animal model to measure

various behaviors, specifically involving motor function. Treatment of rodents with

nicotine increases motor function associated with the startle response (Gould et al., 2005;

Lewis and Gould, 2003; Acri et al., 1995). Specifically, acute treatment of nicotine (0.1

and 0.5 mg/kg, s.c.) stimulates overall motor activity in both male neonates and young

adults (Faraday et al., 2003). Interestingly, following delivery of nicotine to neonates,

they exhibited increases in movements and rearing behaviors; whereas, young adults did

not show these same levels (Faraday et al., 2003). This same stimulatory effect of

nicotine is also present in females treated with similar levels of nicotine (0.1 and

0.5 mg/kg, s.c.) under similar testing parameters (Elliot et al., 2005). Nicotine, however,

appears to be the most effective at increasing motor function in neonatal age ranges rather

in than in young adults (Domino et al., 2001; Bevins and Besheer, 2001; Shoaib and

Shippenberg, 1996).

Amphetamine at low concentrations (0.2, 0.4 and 0.8 mg/kg) increases overall locomotor

behavior in adult rats in a dose-dependent manner (Mobini et al., 2000). The same trend

is also present when compared to moderately higher doses of amphetamine (2 mg/kg),

which show significant dose-dependent increases in locomotor activity (Yates et al.,

-4-

3DJHRI

WIL-99441

2007; Chatterjie et al., 1998). This noted effect of amphetamine increasing of horizontal

and vertical motor activity, total distance covered, and stereotypic behaviors for up to

2 hours post-treatment (Gaytan et al., 1996). Although still elevated when compared to

control animals, amphetamine at even higher doses (6, 10, 12, 16, and 20 mg/kg) actually

becomes less effective at increasing the distance covered and other general locomotorrelated behaviors (Yates et al., 2007).

3. MATERIALS AND METHODS

3.1. TEST SPECIES AND HUSBANDRY

Sprague-Dawley Crl:CD(SD) rats were obtained from Charles River Laboratories, Inc.

(Raleigh, NC, USA). Twenty females with litters (5 pups/sex) were ordered to provide

20 rats/sex/group for testing on PND 13, 17 and 21. The breeder females were

individually housed in plastic maternity cages with nesting material (Bed-O’Cobs®). The

dams and pups remained in these cages until euthanasia on lactation day/PND 21. For

the PND 61 groups, 84 young adult rats/sex were ordered for startle response testing of

80 rats/sex. The animals were housed 2-3/cage (by sex) for 1 week, then individually in

suspended wire mesh cages until euthanasia.

 Environmental controls were set to maintain temperature at 71 ± 5o F and relative

humidity between 30–70%. Air handling units provided a minimum of 10 fresh air

changes per hour. Fluorescent lighting, controlled by timers, provided illumination for a

12-hour (6:00 a.m. – 6:00 p.m.) light/dark photoperiod. Temperature and relative

humidity were monitored continuously. Reverse osmosis-purified water and PMI

Nutrition International, Inc. Certified Rodent LabDiet® 5002 were offered ad libitum

during the course of the study.

3.2. TEST MATERIAL AND PREPARATION

(-)-Nicotine Hydrogen Tartrate Salt was purchased from Sigma Aldrich, St.Louis, MO,

USA. An appropriate amount of nicotine was mixed with the vehicle (0.9% sodium

chloride for injection) to produce dosing concentrations of 0.005 and 0.025 mg/mL with a

corresponding dosage volume of 20 mL/kg. Dosing solutions were prepared on each day

of dose administration.

D–Amphetamine Sulfate was purchased from Sigma Aldrich, St. Louis, MO. An

appropriate amount of amphetamine, corrected for salt content, was mixed with the

vehicle (0.9% sodium chloride for injection) to produce dosing concentrations of 0.2, 1

and 3 mg/mL with a corresponding dosage volume of 1 mL/kg. Dosing solutions were

prepared on each day of dose administration.

On each day of dose administration, a sufficient amount of vehicle was dispensed for

administration to all control groups.

3.3. EXPERIMENTAL DESIGN

For the neonatal phase, four groups of 20 rats/sex received an intraperitoneal injection of

nicotine at 0, 0.1 or 0.5 mg/kg on PND 13, 17 and 21, approximately 3 minutes prior to

assessment of locomotor behavior. For the young adult phase, amphetamine was

administered by an intraperitoneal injection to four groups of 20 rats/sex at 0, 1 or

3 mg/kg on PND 61, approximately 15 minutes prior to assessment of locomotor

behavior. In addition, 3 separate groups of 20 female rats/group at 0, 0.2 or 1 mg/kg on

PND 61 were also administered amphetamine by intraperitoneal injection approximately

15 minutes prior to locomotor assessment. The corresponding dosage volumes were 20

mL/kg for nicotine and 1 mL/kg for amphetamine. All rats were observed twice daily for

moribundity and mortality, once in the morning and once in the afternoon until

euthanasia. Body weights and clinical observations were recorded on each day of dose

administration. The observations included, but were not limited to evaluations for

changes in appearance of skin and fur, eyes, mucous membranes, respiratory and

circulatory systems, autonomic and central nervous systems, somatomotor activity and

behavior. Additional observations, if needed, were documented in the study records.

3.4. BEHAVIORAL TESTING

Twenty neonatal animals/sex/group were assigned to the locomotor activity tests

performed on PND 13, 17 and 21, and 20 young adult animals/sex/group with an

additional 20 young adult females/group were assigned to the locomotor activity test

performed on PND 61 using the automated Kinder Scientific MotorMonitor System

(Kinder Scientific, LLC, Poway, CA, USA). The test session was 60 minutes in

duration, consisting of 6 subintervals lasting 10 minutes each. Locomotor activity was

evaluated as total and ambulatory activity counts obtained over each subinterval

(0-10 minutes, 11-20 minutes, 21-30 minutes, 31-40 minutes, 41-50 minutes and

51-60 minutes) and the entire 60-minute session.

3.5. STATISTICAL ANALYSIS

All analyses were two-tailed for minimum significance levels of 5% and 1%. All

statistical tests were performed by a computer with appropriate programming as

referenced below. Total and ambulatory counts were analyzed, by sex and session, with

a repeated measure analysis of variance (RANOVA). Factors in the model included

treatment group (TRT), time interval (TIME), and the interaction of time interval and

treatment group (TRT*TIME). The SAS® procedure PROC MIXED was used for

analysis with the random effect of animal included as the repeated measurement. The

-8-

WIL-99441

covariance structure across time was selected by comparing Akaike's Information

Criterion.

The monotonic dose-response relationship was evaluated using sequential linear trend

tests based on ordinal spacing of dose levels. The linear dose by time interaction was

evaluated and, if significant at the 0.05 level, trend tests on treatment means were

performed at the 0.05 level for each time interval. If the linear dose by time interaction

was not significant, the trend test was conducted across the pooled time intervals of the

entire session only.

Nonmonotonic dose responses were evaluated whenever no significant linear trends were

detected but TRT and/or TRT*TIME interaction was significant at the 0.01 level. Within

the framework of the RANOVA, pairwise comparisons were made for each individual

test article-treated group with the control group through linear contrasts. If TRT*TIME

was significant, the comparisons were conducted for each time interval. If only the TRT

effect was significant, the comparisons were conducted across the pooled time intervals

of the entire session. These nonmonotonic dose-response comparisons were conducted at

the 0.01 significance level.

The ontogenic profile of activity in control animals was demonstrated by the Kinder

Scientific MotorMonitor System when examining both the mean total and mean

ambulatory activity counts from PND 13, 17 and 21 males and females (Figure 1A and B,

Figure 2A and B). This behavioral profile of motor function is evident by the relatively

low activity in PND 13 neonates, followed by an increase in activity at PND 17 and then

a decrease in activity at PND 21. This is consistent with the development of motor

behavior in male and female neonates when exposed to a novel environment over these

three time points (PND 13, 17 and 21).

Total activity counts measured over each subinterval by the Kinder Scientific

MotorMonitor System in PND 13 male and female treatment groups (Figure 3A and B)

showed a slight tendency of nicotine to increase activity in males and females at

0.5 mg/kg. This effect was more evident in the ambulatory activity counts over

subinterval 1-10 (Figure 4A and B). For both total and ambulatory activity counts in the

PND 13 male and female high nicotine groups (0.5 mg/kg) there was a marked drop from

subinterval 1-10 to 11-20, after which there was no distinction between groups. This

initial elevation is the first sign in the development of an habituation profile, and also

supports the effect of nicotine increasing motor activity that has been documented in the

literature (Domino et al., 2001; Bevins and Besheer, 2001; Shoaib and Shippenberg,

1996).

The PND 17 male (0.1 and 0.5 mg/kg) and female (0.5 mg/kg) nicotine treatment groups

exhibited increased total and ambulatory locomotor behavior over all of the subintervals

(Figure 1A and B, Figure 2A and B). The apparent greater effect of nicotine in the

PND 17 males and females (compared to PND 13) may be due to the tendency of motor

behavior to increase in this age group. Examining each subinterval during behavioral

assessment indicated that the nicotine-treated males and females tended to be more active

(total and ambulatory) than the control groups over the initial 3 subintervals (Figure 5A

and B, Figure 6A and B). This increased level of motor activity is comparable to the

increased activity measurements at similar doses present in the literature (Shoaib and

Shippenberg, 1996; Bevins and Besheer, 2001; Faraday et al., 2003; Elliot et al., 2005).

In addition, an habituation profile was present in each PND 17 male and female group

over the six subintervals.

The nicotine treatment effect, primarily at 0.5 mg/kg, also resulted in an increased mean

total and ambulatory activity in the PND 21 males and females (Figure 1A and B, Figure

2A and B). This effect of nicotine was apparently dose dependent for both males and

females, with the 0.5 mg/kg having the greatest level of activity. The effect of nicotine

on PND 21 motor activity was also more pronounced for the total and ambulatory activity

measurements taken over all six subintervals (Figure 7A and B, Figure 8A and B). In

addition, the development of the habituation profile was more evident in the PND 21

nicotine-treated males and females. Even in this age group (PND 21), the effects of

nicotine at 0.1 and 0.5 mg/kg are consistent with previously published behavioral

assessment research (Shoaib and Shippenberg, 1996; Bevins and Besheer, 2001; Faraday

et al., 2003; Elliot et al., 2005).

The use of the Kinder Scientific MotorMonitor System showed that amphetamine

treatment (1 and 3 mg/kg) increased PND 61 male and female mean total and ambulatory

activity counts (Figure 9A and B). This effect was not dose dependent, because the most

activity was present in the 1 mg/kg amphetamine male and female treatment groups.

However, addition of the amphetamine-treated (0.2 and 1 mg/kg) PND 61 females

indicated that there was a dose-dependent effect of amphetamine (Figure 12A and B) on

mean total and ambulatory activity counts. The 3 mg/kg amphetamine treatment in the

previously mentioned PND 61 males and females resulted in substantially lower level of

mean total activity than in the 1 mg/kg groups, although still above the control groups.

This same decrease in activity was also present in the mean ambulatory data suggesting

that generalized activity or movement (i.e., shaking) was not substituted with an increase

in ambulation. Reports in the literature do indicate that, although amphetamine acts to

increase motor activity, there is a point where amphetamine can become inhibitory in

nature depending on the strain, age, gender and testing paradigm used (Gaytan et al.,

1996; Mobini et al. 2000; Chatterjie et al., 1998; Yates et al., 2007).

Similarly, amphetamine treatment (1 and 3 mg/kg) of the young adult PND 61 males and

females (Figure 10A and B) increased the total activity counts by subinterval in a nondose-related manner. In addition, the ambulatory activity by subinterval for males and

females (Figures 11A and B) was also increased for the majority of motor activity

assessment following amphetamine treatment (1 and 3 mg/kg). An habituation profile

was present for both total and ambulatory activity for the PND 61 control animals, with

the 3 mg/kg amphetamine treatment group only showing some possible habituation

regarding ambulatory activity. The 1 mg/kg treatment groups for both males and females

lacked habituation, with the total and ambulatory activity remaining elevated over all

subintervals. In a similar manner to the total activity, the PND 61 (0, 0.2 and 1 mg/kg)

treated females exhibited a dose response for ambulatory activity (Figure 13 A and B).

Overall, the effect of amphetamine increasing activity above baseline, as well as

inhibiting activity at higher amphetamine doses (3 mg/kg) in the PND 61 males and

females, is consistent with the previously published literature (Gaytan et al., 1996;

Mobini et al. 2000; Chatterjie et al., 1998; Yates et al., 2007).

In conclusion, the motor activity data (i.e. total activity and ambulatory activity) for

Sprague Dawley Crl:CD (SD) rats generated by the Kinder Scientific MotorMonitor

System are consistent with previously reported effects of nicotine and amphetamine on

motor behavior. This motor monitoring system is therefore capable and sensitive enough

to measure increases in motor activity in neonatal and young adult rodents with positive

control agents such as nicotine and amphetamine.

1. ABSTRACT

The objective of this study was to demonstrate the ability of the Kinder Scientific

MotorMonitor System (Kinder Scientific, LLC, Poway, CA, USA) to detect decreases in

activity in response to chlorpyrifos within the U.S. EPA Health Effects Guideline OPPTS

870.6200 (Neurotoxicity Screening Battery) and the Organization of Economic

Cooperation and Development (OECD) Guidelines for Testing of Chemicals Guideline

424 (Neurotoxicity Study in Rodents). In addition, the study evaluated the ability to

detect changes in behavior using a functional observational battery (FOB). Chlorpyrifos

was administered at a single dose of 20 or 100 mg/kg by oral gavage 3.5 hours prior to

behavioral assessment. Male and female Sprague Dawley Crl:CD (SD) rats (6 weeks of

age) were evaluated using a Neurotoxicity Screening Battery consisting of FOB

assessment and locomotor behavior. The FOB detected a general decrease in the

initiation of movement (time to first step in the open field), body temperature and

Rotarod performance, along with impaired gait and increased catalepsy time. Motor

activity (i.e., total and ambulatory activity) measured by the Kinder Scientific

MotorMonitor System showed a consistent decrease in mean activity by both males and

females treated with 100 mg/kg chlorpyrifos. The experimental design used in this study

demonstrated that WIL Research can detect behavioral changes in an FOB, as well as

locomotor effects of chlorpyrifos using the Kinder Scientific MotorMonitor System, and

that the results can be considered to validate methodologies for OPPTS Guideline

870.6200 and OECD Guideline 424.

This study was conducted in accordance with the appropriate provisions of the U.S. EPA

Health Effects Guideline (OPPTS 870.6200), Neurotoxicity Screening Battery and the

OECD Guidelines for Testing of Chemicals Guideline 424, Neurotoxicity Study in

Rodents. The exception is that the study assessments were be completed only during

pretest and at the time of peak effect on study day 0. Validation of laboratory

methodologies and demonstration of the sensitivity of the equipment to detect test articlerelated changes are requirements of these guidelines. WIL Research Laboratories, LLC

chose to evaluate the use of the Kinder Scientific MotorMonitor System to measure

locomotor behavior in control and test article-treated animals using chlorpyrifos, a known

cholinesterase inhibitor used commonly in insecticides.

In rodents, a single dose of chlorpyrifos often results in the presence of tremors, increased

lacrimation and salivation, loss of muscle tone, hypothermia, changes in gait, increased

catalepsy times and inhibited pupil responsiveness (Moser 1995; Mattsson et al., 1996).

When evaluated at the time of peak effect (approximately 3.5 hours post-administration)

these effects, specifically regarding muscle tone and function, are consistent with the

decreased motor activity observed at dose levels of 20, 50 and 100 mg/kg (Moser, 1995).

This was also noted in other studies using higher dose levels (50, 100, 150 and

200 mg/kg), administered once by oral gavage, which were sufficient to cause

generalized decreases in muscle tone and motor activity for both male and female adult

rats (Mattsson et al., 1996). This same trend was also present in low-dose (3 to

12 mg/kg) chronic studies lasting several days to weeks using male and female rats

(PND 30 and 40), where motor activity in the open field was inhibited (Carr et al., 2001).

Further analysis of chlorpyrifos via alternative delivery routes identified impaired visual

discrimination (following oral or subcutaneous administration at 50 mg/kg) and

significantly lowered general activity in the behavioral test battery (following

subcutaneous administration at 250 mg/kg) for up to 18 consecutive days (Bushnell et al.,

2001).

3. MATERIALS AND METHODS

3.1. TEST SPECIES AND HUSBANDRY

Sprague Dawley Crl:CD(SD) rats were obtained from Charles River Laboratories, Inc.

(Raleigh, North Carolina, USA). 48 males and females (nulliparous and non-pregnant) at

3 to 5 weeks of age were ordered for the in-life testing of 12 rats/sex/group for FOB and

motor activity assessment starting at approximately 6 weeks of age. Upon receipt,

animals were housed 2-3/cage by sex. Following acclimation, the animals were

individually housed in clean suspended wire-mesh cages until euthanasia.

Environmental controls were set to maintain temperature at 71 ± 5o F and relative

humidity between 30–70%. Air handling units provided a minimum of 10 fresh air

changes per hour. Fluorescent lighting, controlled by timers, provided illumination for a

12-hour light (6:00 a.m. – 6:00 p.m.)/dark photoperiod. Temperature and relative

humidity were monitored continuously. Reverse osmosis-purified water and PMI

Nutrition International, Inc., Certified Rodent LabDiet® 5002 were offered ad libitum

during the study.

3.2. TEST MATERIAL AND PREPARATION

Chlorpyrifos was purchased from Supelco, Bellefonte, PA, USA. An appropriate amount

of chlorpyrifos was mixed with the vehicle (corn oil) to produce dosing concentrations of

4 and 20 mg/mL, with a corresponding dose volume of 5 mL/kg. Dosing solutions were

prepared daily, stored at room temperature and protected from light prior to dispensation

for dosing.

3.3. EXPERIMENTAL DESIGN

Functional observational battery assessments and locomotor activity (Kinder Scientific

MotorMonitor System) were made at pretest and approximately 3.5 hours post-dose

administration to 4 groups of 12 rats/sex/group on the day of chlorpyrifos administration.

All rats were observed twice daily for moribundity and mortality, once in the morning

and once in the afternoon until euthanasia. Body weight and clinical observations

regarding general appearance were recorded on the day of dose administration. The

observations included, but were not limited to evaluations for changes in appearance of

skin and fur, eyes, mucous membranes, respiratory and circulatory systems, autonomic

3.4. BEHAVIORAL TESTING

Twelve rats/sex/group were evaluated in the FOB and the Kinder Scientific

MotorMonitor System at pretest and on study day 0. The FOB utilized was based on

previously developed protocols which included: home cage, handling, open field,

sensory, neuromuscular and physiological observations (Moser et al., 1991; Irwin, 1968;

Gad, 1982; Moser et al., 1988; Haggerty, 1989; O'Donoghue, 1989). All animals were

Testing was performed by the same technicians, whenever possible, who did not know

for each testing parameter (when necessary) the FOB data presented in this report only

include functional domains that are significantly different from the control group and/or

were affected by test article administration. Locomotor activity was monitored with the

automated Kinder Scientific MotorMonitor System (Kinder Scientific, Poway, CA,

USA). The test session was 60 minutes in duration, consisting of 6 subintervals lasting

10 minutes each. Locomotor activity was evaluated as total and ambulatory activity

counts obtained over each subinterval (0-10 minutes, 11-20 minutes, 21-30 minutes, 31-

40 minutes, 41-50 minutes and 51-60 minutes) and the entire 60-minute session.

3.5. STATISTICAL ANALYSIS

All analyses were two-tailed for minimum significance levels of 5% and 1%. All

statistical tests were performed by a computer with appropriate programming as

-7-

referenced below. Total and ambulatory counts were analyzed, by sex and session, with

a repeated measures analysis of variance (RANOVA). Factors in the model included

treatment group (TRT), time interval (TIME), and the interaction of time interval and

treatment group (TRT*TIME). The SAS® procedure PROC MIXED was used for

analysis with the random effect of animal included as the repeated measurement. The

covariance structure across time was selected by comparing Akaike's Information

Criterion.

Continuous FOB data were subjected to parametric one-way analysis of variance

(ANOVA) to determine intergroup differences (Snedecor, 1980). If significant

differences were determined by the ANOVA, Dunnett’s test (Dunnett, 1964) was used to

compare each control group with the test article-treated groups. Functional Observational

Battery parameters yielding scalar or descriptive data were analyzed by Fisher’s Exact

Test (Steel and Torrie, 1980).

The monotonic dose-response relationship was evaluated using sequential linear trend

tests based on ordinal spacing of dose levels. The linear dose by time interaction was

evaluated and, if significant at the 0.05 level, trend tests on treatment means were

performed at the 0.05 level for each time interval.

Nonmonotonic dose responses were evaluated whenever no significant linear trends were

detected, but TRT and/or TRT*TIME were significant at the 0.01 level. Within the

framework of the RANOVA, pairwise comparisons were made for each individual test

article-treated group with each control group through linear contrasts. If TRT*TIME was

significant, the comparisons were conducted for each time interval. If only the TRT

effect was significant, the comparisons were conducted across the pooled time intervals

of the entire session. These nonmonotonic dose-response comparisons were conducted at

the 0.01 significance level.

All statistical analyses for locomotor activity were conducted by BioSTAT Consultants,

Inc., Portage, MI, USA, using Version 9.1 (SAS Institute, Inc., 2002-2003) software.

4. RESULTS AND DISCUSSION

The FOB performed prior to chlorpyrifos administration (pretest) showed no differences

in handling, sensory, neuromuscular and physiological parameters. Increased urination

(in the open field; p<0.05 or p<0.01, Table 4) by females assigned to the 20 mg/kg

chlorpyrifos groups; as well as a longer time to first step by 20 mg/kg chlorpyrifos treated

males (p<0.01), compared to control groups 1 or 2. However, approximately 3.5 hours

following dose administration, chlorpyrifos-treated animals exhibited test article-related

differences (compared to the control groups) in the home cage, open field, neuromuscular

and physiological parameters, while handling and sensory parameters were largely

unaffected. This was not considered to be test article related since the differences were

not consistent between control groups 1 and 2.

4.1. HOME CAGE AND OPEN FIELD ASSESSMENTS

The first two components of the FOB, including home cage and open field assessments

identified repetitive movement of the mouth and jaw (1 female each at 20 mg/kg and

100 mg/kg and 2 males at 100 mg/kg; Table 2) in the home cage, which is an expected

effect of chlorpyrifos treatment. The open field observations during the FOB test

identified a more robust test article-related effect with an increased time until the

initiation of motor behavior, i.e., the first step taken, for both the 100 mg/kg group males

and females (Table 4, p<0.01). This increased latency compared to both vehicle control

group males and females, indicates that chlorpyrifos treatment prolonged the time to

initiation of motor movement and inhibited motor function. This, along with the general

decline in mean total and ambulatory activity, further suggests that chlorpyrifos impaired

movement. Another aspect of motor movement, gait, was affected by chlorpyrifos

administration (Table 4). The numbers of males and females with normal gait were

decreased in the 100 mg/kg group (the difference was significant [p<0.01] for males

compared to both control groups). Specifically, both sexes showed an increase in the

incidence of hunched body posture; splayed or dragging hind limbs were also noted for

1 male, while 2 females were observed walking on tiptoes. These effects on gait are

consistent with decreases in motor activity as well as the results of previous research

regarding chlorpyrifos and motor behavior (Moser, 1995; Mattsson et al., 1996; Carr et

al., 2001; Bushnell et al., 2001). In addition, there was a significant decrease in the

-9-

3DJHRI

WIL-99443

number of rears exhibited by chlorpyrifos treated females (100 mg/kg) compared to

control group 1 (Table 4, p<0.05).

4.2. NEUROMUSCULAR ASSESSMENT

Neuromuscular impairment was particularly evident in males and females receiving the

100 mg/kg dose, where Rotarod performance (Table 6) was significantly decreased

compared to both control groups (p<0.05 or p<0.01) and decreased compared to pretest;

1 male and 1 female in the 100 mg/kg group also exhibited slight tremors. This would

indicate that there was impaired motor movement and/or balance. Since locomotor

activity data also showed a decline in mean total and ambulatory activity, chlorpyrifos

was indeed acting to impair motor function. In females, there was an apparent increase in

forelimb grip strength (Table 6) at the 20 mg/kg dose (p<0.05); although not significant,

this same group of females also had the greatest grip strength during the pretest

evaluations (Table 5). The FOB data regarding impaired motor movement/balance and

decreased activity are supported by published studies addressing neuromuscular

impairments and chlorpyrifos (Moser 1995; Mattsson et al., 1996).

4.3. PHYSIOLOGICAL ASSESSMENT

Physiological parameters, specifically catalepsy and body temperature, were also affected

by chlorpyrifos treatment in males and/or females (Table 8). Catalepsy time (the length

of time spent motionless) was significantly increased in 100 mg/kg group males (p<0.05).

The increased catalepsy time corresponds to the previously discussed impairments in the

initiation and overall motor behaviors examined. Along with the increased catalepsy

time, there were significantly decreased body temperatures (p<0.01) for males and

females in the 100 mg/kg group. The results are consistent with similar doses used in

published research, which also show increased catalepsy time and decreased body

temperature (Moser 1995; Mattsson et al., 1996; Timofeeva and Gordon, 2002).

4.4. MOTOR ACTIVITY

The motor activity data over all 6 subintervals measured by the Kinder Scientific

MotorMonitor System in the pretest male and female groups show that there was no

difference in mean total and ambulatory activity prior to chlorpyrifos administration

(Figure 1A and 2A). Examining the total and ambulatory activity during the

-10-

3DJHRI

WIL-99443

6 subintervals also shows no difference prior to chlorpyrifos treatment in pretest males

and females (Figure 3A and B, Figure 4A and B). In addition, there was an habituation

profile present for both males and females over the 6 subintervals prior to chlorpyrifos

administration. These similarities were expected, as there was no test article

administered.

There was a significant decrease (p<0.01 or p<0.001) in mean total and ambulatory

activity counts compared to the vehicle control groups following delivery of 100 mg/kg

chlorpyrifos to males and females and following delivery of 20 mg/kg chlorpyrifos to

females (Figure 1B, Figure 2B) approximately 3.5 hours following chlorpyrifos delivery.

With respect to the individual subintervals of total and ambulatory activity, there were

similar decreases in activity following chlorpyrifos treatment over the first 2 subintervals

(1-10 minutes and 11-20 minutes) in males at 100 mg/kg and females at 20 and

100 mg/kg (Figure 5A and B, Figure 6A and B). These decreases in activity also

followed a dose-dependent profile with the highest level of chlorpyrifos (100 mg/kg)

resulting in the lowest overall activity. Females appeared to be more sensitive to

chlorpyrifos treatment, as both the low and high doses (20 and 100 mg/kg, respectively)

resulted in decreased activity, similar to behavioral results observed in the FOB.

Because there were no differences in motor activity prior to chlorpyrifos administration,

the decreased total and ambulatory activity can be attributed to chlorpyrifos. These

decreases in motor activity are also consistent with the results of previous studies at

similar dose levels of chlorpyrifos (Moser 1995; Mattsson et al., 1996; Carr et al., 2001;

Bushnell et al., 2001).

5. CONCLUSION

In conclusion, the data generated using the functional observational battery and Kinder

Scientific MotorMonitor System in male and female Sprague Dawley Crl:CD (SD) rats

are consistent with the cited effects of chlorpyrifos on motor behavior. These procedures

are therefore capable and sensitive enough to detect reductions in motor function with the

positive control agent, chlorpyrifos, and can be considered to validate methodologies for

OPPTS Guideline 870.6200 and OECD Guideline 424.

AN INTER-OBSERVER RELIABILITY STUDY OF TECHNICIANS

ASSIGNED TO PERFORM FUNCTIONAL OBSERVATIONAL

BATTERY ASSESSMENTS IN RATS

Study Date Range: December 14, 2001 - October 9, 2002

STUDY OBJECTIVE:

The objective of this study was to train personnel to conduct the Functional

Observational Battery (FOB) and to assess inter-observer reliability of the same

technicians. FOB. inter-observer reliability studies serve as training for new employees,

as well as on-going training for current employees.

CONTROL ARTICLES:

Deionized water was used as the negative control article. Two positive control articles,

3,3 ́-Iminodipropionitrile (IDPN) and Parathion, were used to elicit behavioral changes in

the animals. IDPN was administered orally at 2000 mg/kg, and Parathion was

administered orally at 4 mg/kg. All control articles were administered as a single dose.

TEST SYSTEM:

All animals used on the study were female Sprague-Dawley Crl:CD® (SD)IGS BR rats

obtained from the WIL Research Laboratories, Inc. stock colony. Animals were

randomly assigned to treatment groups using a computer program. The study was

conducted according the protocol and WIL standard operating procedures.

ENVIRONMENTAL CONDITIONS:

The animals were housed and maintained under conditions consistent with maintaining

good health. Temperature and relative humidity were set to maintain at 71 ± 5° C and

30-70%, respectively, in a room with a 12 hour light (6 a.m. to 6 p.m.)/dark photoperiod.

Temperature and relative humidity were recorded once daily. The facilities at WIL

Research Laboratories, Inc. are fully accredited by the Association for Assessment and

Accreditation of Laboratory Animal Care International (AAALAC International).

VIABILITY OBSERVATIONS:

The rats were observed for mortality/moribundity and general condition twice daily, in

the morning and in the afternoon.

BODY WEIGHTS:

Body weights were recorded on days of dosing for calculation of doses only.

FUNCTIONAL OBSERVATIONAL BATTERY ASSESSMENTS:

The Functional Observational Battery used at WIL Research Laboratories, Inc. is based

on previously developed protocols (Moser et al., 1999; Irwin, 1968; Gad, 1982; Moser et

al., 1988; Haggerty, 1989; O’Donoghue, 1989). Testing for Phase III (described below)

was performed by trained technicians who did not know the animal’s group assignment.

The time of testing was determined by the Study Director based on the appearance of the

expected behavioral signs following dosing. Animals were observed for the following

parameters as described below (see WIL standard operating procedure No. T1-112, as

revised, for a description of scoring criteria):

HOME CAGE OBSERVATIONS:

Posture Biting

Convulsions/Tremors Palpebral (eyelid) closure

Feces consistency

HANDLING OBSERVATIONS:

Ease of removal from cage Ease of handling animal in hand

Lacrimation/chromodacryorrhea Salivation

Piloerection Fur appearance

Palpebral closure Respiratory rate/character

Red/crusty deposits Mucous membranes/eye/skin color

Eye prominence Muscle tone

OPEN FIELD OBSERVATIONS: (evaluated over a 2-minute observation period)

Mobility Gait

Rearing Arousal

Convulsions/tremors Urination/defecation

Grooming Gait score

Bizarre/stereotypic behavior Backing

Time to first step (seconds)

SENSORY OBSERVATIONS:

Approach response Touch response

Startle response Tail pinch

Pupil response Eyeblink response

Forelimb extension Hindlimb extension

Air righting reflex Olfactory orientation

The study design consisted of three distinct phases to ensure the most adequate training

and reliability among the technicians. Phases were designed as a progression to allow for

3DJHRI

COMPANY SANITIZED DOES NOT CONTAIN CONFIDENTIAL BUSINESS INFORMATION
WIL-99263

training and discussion prior to the final phase, which evaluated the inter-observer

reliability. The phases of testing are described as follows:

PHASE I:

Phase I testing consisted of FOB assessments on naive stock animals. Each

technician observed up to 60 rats through the entire FOB assessment. The purpose of

Phase I testing was to ensure consistent and accurate use of all equipment and to gain

a strong knowledge of the stereotypic behavior of naive animals. All rats used in

Phase I testing were returned to stock following FOB assessments.

PHASE II:

Phase II testing consisted of an open discussion of each animal’s observations

conducted in a group setting. Two animals per group were dosed with Parathion,

IDPN or deionized water and evaluated by the observers once the effects were

apparent. Phase II allowed for open discussion of observations and interpretation of

the findings. All animals used in Phase II testing were euthanized by carbon dioxide

inhalation and carcasses discarded following testing.

PHASE III:

Phase III testing consisted of three animals per group dosed with a single dose of

Parathion, IDPN or deionized water and observed at a time determined by the Study

Director. Each technician individually recorded observations for each animal to

evaluate the inter-observer reliability. All animals used in Phase III testing were

euthanized by carbon dioxide inhalation and carcasses discarded following testing.

CRITERIA FOR EVALUATION OF TECHNICIANS:

The following criteria were used to evaluate the ability of technicians to reliably

distinguish signs of neurotoxicity.

1. No omission of findings within the categories of Home Cage Observations,

Handling Observations, Open Field Observations and Sensory Observations.

2. A difference of no more than two grades (severity) for a given finding in each

category.

RESULTS:

VIABILITY:

All animals survived until scheduled euthanasia.

COMPANY SANITIZED DOES NOT CONTAIN CONFIDENTIAL BUSINESS INFORMATION
WIL-99263

FUNCTIONAL OBSERVATIONAL BATTERY ASSESSMENTS:

Technicians were consistent in the findings reported when deionized water, IDPN or

Parathion was administered (Table 1). There were no obvious or gross

inconsistencies among the calls.

It was determined that the previously established criteria for evaluation were fulfilled

to a degree deemed acceptable by the Study Director. It should be noted that there

were a few apparent omissions of findings (Table 2) which upon further review were

found to be of no practical significance.

CONCLUSIONS:

It was determined that the technicians fulfilled the criteria for reliably observing FOB

parameters to assess behavioral changes in rats in a manner consistent with good science

and WIL Research Laboratories, Inc. standard operating procedures.

AN INTER-OBSERVER RELIABILITY STUDY OF INDIVIDUALS

ASSIGNED TO PERFORM FUNCTIONAL OBSERVATIONAL

BATTERY OBSERVATIONS FOR NEUROTOXICITY STUDIES

Study Date Range: April 13-29, 2004

STUDY OBJECTIVE:

The objective of this study was to train personnel to conduct the Functional

Observational Battery (FOB) and to assess inter-observer reliability of the same

individuals. The inter-observer reliability also included one individual that had been

previously trained to further demonstrate inter-observer reliability of the newly trained

individuals with those currently approved to conduct neurotoxicity studies. FOB

inter-observer reliability studies serve as training for new employees, as well as on-going

training for current employees.

CONTROL ARTICLES:

Mazola® corn oil was used as the negative control article. Three positive control articles,

3,3 ́-Iminodipropionitrile (IDPN), Parathion and d-Amphetamine, were used to elicit

behavioral changes in the animals. IDPN was administered orally (gavage) at

2000 mg/kg, Parathion was administered orally (gavage) at 4 mg/kg, and d-Amphetamine

was administered by intraperitoneal injection at 2 mg/kg. All positive and negative

control articles were administered as a single dose.

TEST SYSTEM:

All animals used on the study were female Sprague-Dawley Crl:CD® (SD)IGS BR rats

obtained from the WIL Research Laboratories, Inc. stock colony. Animals were

randomly assigned to treatment groups using a computer program. The study was

conducted according the protocol and WIL standard operating procedures.

ENVIRONMENTAL CONDITIONS:

The animals were housed and maintained under conditions consistent with maintaining

good health. Temperature and relative humidity were set to maintain at 71 ± 5° C and

30-70%, respectively, in a room with a 12 hour light (6 a.m. to 6 p.m.)/dark photoperiod.

Temperature and relative humidity were recorded once daily. The ventilation rate was set

at a minimum of 10 room air changes per hour using 100% fresh air. The facilities at

WIL Research Laboratories, Inc. are fully accredited by the Association for Assessment

and Accreditation of Laboratory Animal Care International (AAALAC International).

COMPANY SANITIZED DOES NOT CONTAIN CONFIDENTIAL BUSINESS INFORMATION
WIL-99310

VIABILITY OBSERVATIONS:

The rats were observed for mortality/moribundity and general condition twice daily, in

the morning and in the afternoon.

BODY WEIGHTS:

Body weights were recorded on days of dose administration for calculation of doses only.

FUNCTIONAL OBSERVATIONAL BATTERY ASSESSMENTS:

The Functional Observational Battery used at WIL Research Laboratories, Inc. is based

on previously developed protocols (Moser et al., 1999; Irwin, 1968; Gad, 1982; Moser et

al., 1988; Haggerty, 1989; O’Donoghue, 1989). Testing for the Inter-observer Reliability

testing (described below) was performed by trained technicians who did not know the

animal’s group assignment. The time of testing was determined by the Study Director

based on the appearance of the expected behavioral signs following dosing. Animals

were observed for the following parameters as described below (see WIL standard

operating procedure No. T1-112, as revised, for a description of scoring criteria):

HOME CAGE OBSERVATIONS:

Posture Biting

Convulsions/Tremors Palpebral (eyelid) closure

Feces consistency

HANDLING OBSERVATIONS:

Ease of removal from cage Ease of handling animal in hand

Lacrimation/chromodacryorrhea Salivation

Piloerection Fur appearance

The study design consisted of three distinct phases to ensure the most adequate training

and reliability among the technicians. Phases were designed as a progression to allow for

training and discussion prior to the final phase, which evaluated the inter-observer

reliability. The phases of testing are described as follows:

PHASE I:

Phase I testing consisted of FOB assessments on naive stock animals. Each

technician observed up to 60 rats through the entire FOB assessment. The purpose of

Phase I testing was to ensure consistent and accurate use of all equipment and to gain

a strong knowledge of the stereotypic behavior of naive animals. All rats used in

Phase I testing were returned to stock following FOB assessments.

PHASE II:

Phase II testing consisted of an open discussion of each animal’s observations

conducted in a group setting. Two animals per group were dosed with IDPN,

Parathion, d-Amphetamine or corn oil and evaluated by the observers once the effects

were apparent. Phase II allowed for open discussion of observations and

interpretation of the findings. All animals used in Phase II testing were euthanized by

carbon dioxide inhalation and carcasses discarded following testing.

PHASE III:

Inter-observer Reliability testing consisted of three animals per group dosed with a

single dose of Parathion, IDPN, d-Amphetamine or corn oil and observed at a time

determined by the Study Director or designee. Each observer individually recorded

observations for each animal to evaluate the inter-observer reliability. All animals

used in Inter-observer Reliability testing were euthanized by carbon dioxide

inhalation and carcasses discarded following testing.

CRITERIA FOR EVALUATION OF TECHNICIANS:

The following criteria were used to evaluate the ability of technicians to reliably

distinguish signs of neurotoxicity.

1. No omission of findings within the categories of Home Cage Observations,

Handling Observations, Open Field Observations and Sensory Observations.

3DJHRI

COMPANY SANITIZED DOES NOT CONTAIN CONFIDENTIAL BUSINESS INFORMATION
WIL-99310

2. A difference of no more than two grades (severity) for a given finding in each

category.

RESULTS:

VIABILITY:

All animals survived until scheduled euthanasia.

FUNCTIONAL OBSERVATIONAL BATTERY ASSESSMENTS:

Observers B, C, D and E were consistent in the findings reported when corn oil,

IDPN, Parathion or d-Amphetamine was administered (Table 1). There were no

obvious or gross inconsistencies among the calls with the exception of observer E

who differed consistently when evaluating pupillary response. Therefore, these four

observers were considered to have met acceptable for performing the functional

observational battery on neurotoxicity studies. However, prior to working

independently on studies, observer E will undergo additional training and

demonstrate proficiency in the evaluation of pupillary response.

Observer A differed significantly from the common response of the other observers in

several categories. Therefore, observer A was not considered to have met acceptable

criteria for performing functional observational battery testing on neurotoxicity

studies.

It should be noted there were six apparent omissions of observations (Table 2) which

upon further review were found to be of no consequence.

Procedure

The FOB was performed on those study days specified in the study protocol. Test animals 

were removed from their "home cage" and placed into a separate bank in replicate order if 

the animals are not normally housed in replicate order with blinded cage cards. Test animals 

were allowed a minimum of 15 minutes in this new caging prior to the start of the FOB. 

Test animals were removed from this caging one at a time on the designated day of testing, 

and unless specified by study protocol were taken through the FOB in the following order: 

FOB1 (inclusive of categories 1a-1f and 2a), FOB2 (inclusive of categories 2b-2o, 3a-3m 

and 4a-4J) and FOB3 (inclusive of categories 5a-5d and 6a-6c).

Page 14 

 b. Grip Strength - hind and forelimb

 

 Forelimb and hindlimb grip strength were measured using a device similar to the 

one described by Meyer et al (Neurobehav. Toxicol. 1:233-239, 1979). The 

animal was allowed to grip a T-shaped grip bar with its forepaws and was pulled 

back gently along a platform until its grip was broken. As the backward 

locomotion continued, the animal's hindpaws reached a T-shaped rearlimb grip 

bar, which it was allowed to grasp and then forced to release by continued 

pulling. Mark-10 series EG digital force gauge (Mark-10 Corporation, 

Copiague, NY) was used to record the maximum strain required to break 

forelimb and hindlimb grip. The average of three valid measurements was taken 

as the animal's score for each grip strength measure. Grip strength 

measurements were recorded as grams (g). 

 c. Rotarod Performance

 During the pretest period, the animals were trained to walk on a rotarod (a 

7.0-cm-diameter rod rotating at 12 rpm; AccuScan Instruments, Inc., Columbus, 

Ohio) for a period of two minutes. The duration of time each animal remained 

on the rotarod (up to a maximum time of 120 seconds) during testing was 

recorded.

 d. Hindlimb Foot Splay

 The heel pads of the hindfeet of the animal were painted with a non-toxic 

water-based paint. Animals are dropped from a horizontal position 

approximately 30 cm above a table onto the Hindlimb Foot Splay Test sheet. 

The distance (to the nearest millimeter) between the inner edge of the ink blots 

made by each foot was measured. The test was repeated two more times; and 

the average score (to the nearest millimeter) of the latter two trials was 

calculated.

6. PHYSIOLOGICAL OBSERVATIONS

 a. Catalepsy

 The animal was placed on four Plexiglas® platforms (35 mm high and 40 mm in 

diameter) that were a distance of 100 mm from each other between the fore and 

hind feet and 60 mm between right and left feet (when measured from the center 

of the platforms). The time each animal remained on the four platforms was 

recorded. The duration of immobility was measured (up to a maximum time of 

60 seconds). 

3DJHRI

COMPANY SANITIZED DOES NOT CONTAIN CONFIDENTIAL BUSINESS INFORMATION
Page 15 

 b. Body Temperature

 A thermometer was inserted into the rectum of the animal, and the body 

temperature was recorded after an equilibration period of approximately 

30 seconds. Temperatures were recorded to the tenth (0.1) of a degree. 

 c. Body Weight

 The weight of the animal was recorded. 

The Functional Observational Battery is normally recorded on-line via the 

"IFOB" program in NT-module. In the event that the Data Management System 

is unavailable for on-line data collection, data are hand-recorded on the 

Functional Observational Battery Individual Data Sheets (T1-228, as revised). 

When appropriate, the hand-recorded data are late entered into the Data 

Management System.

Statement of Quality Control 

This report was quality checked in accordance with BioSTAT Procedural Guideline 2.2 

(Quality Control Process for Tables and Reports). The statistical methodology and 

results of inferential statistics were verified by an independent quality control statistician.

Based on these documented quality control activities, it is concluded that the statistical 

results incorporated in this report accurately reflect the statistical analysis of data 

received by BioSTAT.

1 Statistical Methodology 

1.1 Analysis Endpoints 

x Motor Activity 

o Total Count 

o Ambulatory Count 

1.2 Motor Activity Analysis Methodology 

Each analysis endpoint was analyzed, by sex and session, with a repeated measure 

analysis of variance (RMANOVA). Factors in the model included treatment group (TRT), 

time interval (TIME), and the interaction of time interval and treatment group 

(TRT*TIME). The SAS® procedure PROC MIXED was used for analysis with the 

random effect of animal included as the repeated measurement. The covariance structure 

across time was selected by comparing Akaike’s Information Criterion (AIC). 

The monotonic dose response relationship was evaluated using sequential linear trend 

tests based on ordinal spacing of dose levels. The linear dose by time interaction 

(LinTrt*Time) was evaluated and, if significant at the 0.05 level, trend tests on treatment 

means were performed at the 0.05 level for each time interval. If the linear dose by time 

interaction was not significant, the trend test was conducted across the pooled time 

intervals of the entire session only. 

Nonmonotonic dose responses were evaluated whenever no significant linear trends were 

detected but TRT and/or TRT*TIME interaction was significant at the 0.01 level. Within 

the framework of the RMANOVA, pairwise comparisons were made for each individual 

treated group with the control group through linear contrasts. If TRT* TIME was 

significant, the comparisons were conducted for each time interval. If only the TRT 

effect was significant, the comparisons were conducted across the pooled time intervals 

of the entire session. These nonmonotonic dose response comparisons were conducted at 

the 0.01 significance level. 

All statistical analyses were conducted using SAS® software.

Tables Legend 

Motor Activity: For each analysis endpoint (study period/sex/endpoint), data are 

summarized by treatment group for each post-dose time interval, overall (mean across 

post-dose time intervals), and cumulative across post-dose time intervals. P-values for 

interaction terms are shown at the bottom of the table. If LinTrt*Time was not 

significant, sequential trend testing (described below) was conducted across the pooled 

time intervals only and the p-values are reported in the “Overall” row. “NT” (not tested) 

is reported for the p-value in the individual time interval rows. If LinTrt*Time was 

significant, sequential trend testing was conducted for each individual time interval as 

well as across the pooled time intervals. P-values are reported in the individual time 

interval and “Overall” rows. 

Sequential trend tests: All dose groups are included in an initial trend test. If the trend 

test is not significant it is concluded that there is no significant dose-related trend and no 

further testing is conducted. If the trend test is significant, the highest dose group is 

flagged as significant and a trend test is conducted excluding the highest dose group. The 

sequence of trend tests continues until a test is not significant or the lowest nonzero dose 

is flagged as significant.
