Published: February 2006

AbstractTaste‐aversion (TA) learning was measured to determine whether exposure to high‐voltage direct current (HVdc) static electric fields can produce TA learning in male Long Evans rats. Fifty‐six rats were randomly distributed into four groups of 14 rats each. All rats were placed on a 20 min/day drinking schedule for 12 consecutive days prior to receiving five conditioning trials. During the conditioning trials, access to 0.1 % sodium saccharin‐flavored water was given for 20 min, followed 30 min later by one of four treatments. Two groups of 14 rats each were individually exposed to static electric fields and air ions, one group to +75 kV/m (+2 × 105 air ions/cm3) and the other group to −75 kV/m (‐2 × 105 air ions/cm3). Two other groups of 14 rats each served as sham‐exposed controls, with the following variation in one of the sham‐exposed groups: This group was subdivided into two subsets of seven rats each, so that a positive control group could be included to validate the experimental design. The positive control group (n = 7) was injected with cyclophosphamide 25 mg/kg, i.p., 30 min after access to saccharin‐flavored water on conditioning days, whereas the other subset of seven rats was similarly injected with an equivalent volume of saline. Access to saccharin‐flavored water on conditioning days was followed by the treatments described above and was alternated daily with water “recovery” sessions in which the rats received access to water for 20 min in the home cage without further treatment. Following the last water‐recovery session, a 20 min, two‐bottle preference test (between water and saccharin‐flavored water) was administered to each group. The positive control group did show TA learning, thus validating the experimental protocol. No saccharin‐flavored water was consumed in the two‐bottle preference test by the cyclophosphamide‐injected, sham‐exposed group compared to 74% consumed by the saline‐injected sham‐exposed controls (P <.0001). Saccharin‐preference data for the static field‐exposed groups showed no TA learning compared to data for sham‐exposed controls. In summary, exposure to intense static electric fields and air ions did not produce TA learning as assessed by this particular design. © 1995 Wiley‐Liss, Inc.
Do ELF magnetic fields affect human reaction time?
Authors: Podd John V. , Whittington Craig J. , Barnes Geoffrey R. G. , Page Wyatt H. , Rapley Bruce I. 
Published: February 2006

AbstractTwo double‐blind studies were run in an attempt to confirm the finding that a 0.2 Hz magnetic field affects simple reaction time (RT) in humans, whereas a 0.1 Hz field does not. In the first experiment, 12 volunteer subjects were exposed to a continuous 0.2 Hz, 0.1 Hz, or sham field in a fully counter‐balanced, within‐subjects design. Subjects were run singly for one condition each day over 3 consecutive days with a field strength of 1.1 mT and a daily exposure duration of 5 min. Neither magnetic field had any effect on RT at any time during the exposure. One condition of a second study, using a new group of 24 volunteer subjects, also failed to find any field effects at 0.2 Hz. Additionally, the second study failed to show any effects when the frequency, flux density, and field orientation were set according to parametric resonance theory. It is suggested that, although ELF magnetic field effects on human behaviour may be elusive, future research can improve detection rates by paying greater attention to reducing error variance and increasing statistical power. © 1995 Wiley‐Liss, Inc.
Effect of magnetic fields on rodent monooxygenase enzymes
Authors: Carratore R. Del , Morichetti E. , Della Croce C. , Bronzetti G. 
Published: February 2006

AbstractThe effects of 50 Hz, 1.2 mT magnetic fields (MFs) were tested on hepatic monooxygenase enzymes of basal and β‐naphthoflavone‐phenobarbital‐preinduced rats and mice. An inductive effect on cytochrome P‐450 level and on some enzymatic cytochrome P‐450‐dependent activities was observed in basal mice after MF exposure. Enzymatic activities in preinduced mice and rats were reduced by MFs, the degree of reduction depending on the enzyme. A specific inhibitory effect was determined in some of the assayed activities and in the relative peculiar P‐450 isoforms detected by Western blot analysis. © 1995 Wiley‐Liss, Inc.
Effects of 50 Hz magnetic fields on mouse spermatogenesis monitored by flow cytometric analysis

Published: February 2006

AbstractFlow cytometry (FCM) was performed to monitor the cellular effects of extremely‐low‐frequency magnetic field on mouse spermatogenesis. Groups of five male hybrid F1 mice aged 8–10 weeks were exposed to 50 Hz magnetic field. The strength of the magnetic field was 1.7 mT. Exposure times of 2 and 4 h were chosen. FCM measurements were performed 7, 14, 21, 28, 35, and 42 days after treatment. For each experimental point, a sham‐treated group was used as a control. The possible effects were studied by analyzing the DNA content distribution of the different cell types involved in spermatogenesis and using the elongated spermatids as the reference population. The relative frequencies of the various testicular cell types were calculated using specific software. In groups exposed for 2 h, no effects were observed. In groups exposed for 4 h, a statistically significant (P < 0.001) decrease in elongated spermatids was observed at 28 days after treatment. This change suggests a possible cytotoxic and/or cytostatic effect on differentiating spermatogonia. However, further studies are being carried out to investigate the effects of longer exposure times. © 1995 Wiley‐Liss, Inc.
Biologic effects of prolonged exposure to ELF electromagnetic fields in rats: II. 50 Hz magnetic fields

Published: February 2006

AbstractTo provide possible laboratory support to health risk evaluation associated with long‐term, low‐intensity magnetic field exposure, 256 male albino rats and an equal number of control animals (initial age 12 weeks) were exposed 22 h/day to a 50 Hz magnetic flux density of 5 μmT for 32 weeks (a total of about 5000 h). Hematology was studied from blood samples before exposure to the field and at 12 week intervals. Morphology and histology of liver, heart, mesenteric lymph nodes, and testes as well as brain neurotransmitters were assessed at the end of the exposure period. In two identical sets of experiments, no significant differences in the investigated variables were found between exposed and sham‐exposed animals. It is concluded that continuous exposure to a 50 Hz magnetic field of 5 μT from week 12 to week 44, which makes up ˜70% of the life span of the rat before sacrifice, does not cause changes in growth rate, in the morphology and histology of liver, heart, mesenteric lymph nodes, testes, and bone marrow, in hematology and hematochemistry, or in the neurotransmitters dopamine and serotonin. © 1995 Wiley‐Liss, Inc.
Sinusoidal 50 Hz 500 μT magnetic field has no acute effect on urinary 6‐sulphatoxymelatonin in wistar rats

Published: February 2006

AbstractThe effect of a 50 Hz, vertical magnetic field on the excretion of urinary 6‐sulphatoxymelatonin (aMT6s) of male and female Wistar rats was studied in a self‐controlled experiment. Twenty rats were kept in metabolic cages under 9:15 h light:dark conditions. The urine of the animals was collected twice per day for 5 consecutive days. The concentration of aMT6s in the rat urine was measured by 125I radioimmunoassay. The rats were exposed to 5 and 500 μT flux density for 24 h. The excretion of urinary aMT6s did not show significant changes during or after magnetic field exposure. © 1995 Wiley‐Liss, Inc.
Action of 50 Hz magnetic fields on cyclic AMP and intercellular communication in monolayers and spheroids of mammalian cells
Authors: Schimmelpfeng Jutta , Stein Johannes‐Christoph , Dertinger Hermann 
Published: February 2006

AbstractTo investigate the influence of physiological parameters such as cell density and three‐dimensional cell contact on the biological action of a 2 mT/50 Hz magnetic field, mouse fibroblasts were exposed as monolayers and as multicellular spheroids. Changes in cyclic AMP content of cells and alterations in gap junction‐mediated intercellular communication were measured immediately after 5 min of exposure to the field. In monolayers of intermediate cell density (1 × 105 cells/cm2), the field treatment caused an increase in cAMP to 121% of the control level, whereas, at 3 × 105 cells/cm2 (near confluence), a decrease to 88% of the unexposed cells was observed. Furthermore, field exposure stimulated gap‐junction communication to 160% of the control level as determined by Lucifer yellow dye exchange. In spheroids, alterations in the radial profile of cellular cAMP were observed that were due both to field‐induced local cAMP changes and to increased gap‐junction permeability for this second messenger, the latter causing radial cAMP gradients to be flattened. The results indicate a strong dependence of field action on physiological parameters of the system exposed. © 1995 Wiley‐Liss, Inc.
Review: Multipoint binding and heterogeneity in immobilized metal affinity chromatography
Authors: Johnson Robert D. , Arnold Frances H. 
Published: February 2006

AbstractStudies carried out using engineered proteins clearly demonstrate that adsorption to derivatized surfaces involves multiple interactions between functional groups on the protein and complementary sites distributed on the surface. The fact that adsorption involves multipoint interactions has important implications for the design of separations processes and for the interpretation of heterogeneity in biological recognition phenomena. Increasing the density of surface metal sites (immobilized copper ions) is found to be functionally equivalent to increasing the number of metal‐coordinating groups on the protein (histidines and deporotonated amines), m in that both processes increase the likelihood of simultaneous interactions between the protein and the surface. A consequence of multiple‐site interactions is a significant in crease in protein binding affinity that depends on the arrangement of surface sites. A protein will show the highest affinity for arrangements of surface sites which best match its own pattern of functioal groups and will show lower affinity for less optimal arrangements, resulting in binding that is inherently heterogeneous. We have found that reversible protein adsorption in immobilized metal affinity chromatography (IMAC) is described by the Temikin model, which characterizes binding heterogeneity by a uniform distribution of binding energies over the population of surface binding sites. © 1995 John Wiley & Sons, Inc.
