[ { "id": "15825391__text", "type": "abstract", "text": [ "Molecular basis for the selective toxicity of amphotericin B for yeast and filipin for animal cells. Among the polyene antibiotics, many, like filipin, cannot be used clinically because they are toxic; amphotericin B, however, is useful in therapy of human fungal infections because it is less toxic. Both the toxicity of filipin and the therapeutic value of amphotericin B can be rationalized at the cellular and molecular level by the following observations: (i) these polyene antibiotics showed differential effects on cells; filipin was more potent in lysing human red blood cells, whereas amphotericin B was more potent in inhibiting yeast cell growth; and (ii) the effects of filipin were more efficiently inhibited by added cholesterol, the major membrane sterol in human cells, whereas the effects of amphotericin B were more efficiently inhibited by ergosterol, the major membrane sterol in yeast. The simplest inference is that the toxicity and effectiveness of polyenes are determined by their relative avidities for the predominant sterol in cell membranes." ], "offsets": [ [ 0, 1069 ] ] } ]

We have shown that MCF-7 cells treated with 100 nM 1,25(OH)2D3 exhibit characteristic apoptotic morphology (pyknotic nuclei, chromatin and cytoplasmic condensation, nuclear matrix protein reorganization) within 48 h. In the experiments reported here, we examined the interactions between 1,25(OH)2D3 and the antiestrogen 4-hydroxytamoxifen (TAM), which also induces apoptosis in MCF-7 cells. Our data suggest that TAM significantly potentiates the reduction in cell number induced by 1,25(OH)2D3 alone. Combined treatment with 1,25(OH)2D3 and TAM enhances the degree of apoptosis assessed using morphological markers that identify chromatin and nuclear matrix protein condensation. We have selected a subclone of MCF-7 cells resistant to 1,25(OH)2D3 (MCF-7D3Res). These cells express the vitamin D receptor and exhibit doubling times comparable to the parental MCF-7 cells, even when grown in 100 mM 1,25(OH)2D3. Treatment of both parental and resistant MCF-7 cells with TAM induces apoptosis and clusterin. These data emphasize that apoptosis can be induced in MCF-7 cells either by activation of vitamin-D-mediated signalling or disruption of estrogen-dependent signalling." ], "offsets": [ [ 0, 1427 ] ] } ]

[ { "id": "2981680__text", "type": "abstract", "text": [ "Intestinal absorption of arsenate in the chick. The intestinal absorption of arsenate(As(V)) has been investigated in the chick by means of the in situ ligated duodenal loop technique. By this procedure, it was observed that arsenate is rapidly and essentially completely absorbed (80-95%) from the lumen at As(V) concentrations up to 5 mM, declining to about 50% absorption at 50 mM. Transfer from the intestinal lumen to the mucosal cells at low As(V) concentration (0.1 mM) is rapid, while transfer from the mucosal cells to the body occurs more slowly. At stable As(V) concentrations greater than 1 mM, fractional mucosal cell accumulation of As(V) remains constant, while fractional transfer to the body declines. However, total mucosal accumulation of As(V) and that transferred to the body increase in a linear logarithmic fashion from 0.05 to 5 mm As(V). The results indicate that As(V) readily penetrates both the mucosal and serosal surfaces of the epithelial membrane. Furthermore, arsenate and phosphate do not appear to share a common transport pathway in the duodenum and no evidence was obtained for any interaction between the two at this level. Vitamin D3 administration to rachitic chicks was effective in significantly elevating duodenal arsenate absorption, acting primarily to enhance serosal transport." ], "offsets": [ [ 0, 1324 ] ] } ]

To determine whether probenecid has a direct effect on the distribution of cloxacillin, the elimination and distribution of cloxacillin was studied in six patients, five lacking kidney function and one with a partially impaired renal function, in the presence or absence of probenecid. No significant difference was found between the mean values of the volume of distribution of cloxacillin with and without probenecid (13.0 and 12.6 liters, respectively). Thus, the hypothesis of Gibaldi et al. could not be confirmed for cloxacillin in patients lacking kidney function. In spite of the absence of kidney function, the value of the elimination rate constant was significantly decreased in the presence of probenecid (from 0.326 to 0.263/h).

However, the effects of stress and glucocorticoids on the subjective and behavioral effects of psychostimulants have not been well studied in humans. OBJECTIVES: To examine the effects of acute hydrocortisone pretreatment on the subjective and behavioral effects of d-amphetamine. METHODS: Hydrocortisone (100 mg) and d-amphetamine (20 mg) were administered orally to 16 healthy male and female volunteers in a four-session, placebo-controlled, within-subject, crossover design. To prevent stomach irritation, subjects received rantidine hydrochloride before each experimental session. Dependent measures included self-reported mood and subjective effects (Addiction Research Center inventory, the profile of mood states, and a series of visual analogue scales), vital signs, salivary cortisol, and psychomotor performance. RESULTS: Hydrocortisone elevated salivary cortisol levels, produced modest dysphoria, and reduced subjects' reports of wanting more drug. However, hydrocortisone pretreatment did not affect any of the physiological, behavioral, or subjective effects of d-amphetamine. CONCLUSIONS: In contrast to the effects of glucocorticoids in rodent studies, these results indicate that an acute increase in cortisol does not enhance the psychostimulant effects of d-amphetamine in humans." ], "offsets": [ [ 0, 1512 ] ] } ]

The availability of potent non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens for antiretroviral therapy and concerns regarding protease inhibitor (PI)-related metabolic disturbances have led to significant shifts in treatment practices in HIV infection. NNRTI-based regimens may have several advantages over PI-based therapy for initial or prolonged therapy, including more convenient administration regimens, lower tablet volume, fewer drug interactions, and central nervous system penetration. No data from prospective clinical trials currently exist comparing the 3 approved agents (efavirenz, nevirapine or delavirdine). Both efavirenz and nevirapine have been compared to triple therapy with the PI indinavir over 48 weeks as initial therapy, with similar responses being observed with nevirapine regimens and superiority observed with efavirenz. A smaller 24-week study has suggested nevirapine may be superior to the PI nelfinavir. Limited comparative data in patients with high viral loads treated with nevirapine- or delavirdine-based regimens currently exist. However, cohort data and selected patient data from clinical trials suggest comparable activity to PI-based regimens in these patients. The superiority of efavirenz over indinavir-based regimens has been observed in comparative data in a subset of patients with high viral loads. In treatment-experienced patients, available uncontrolled data suggest these agents contribute to regimen efficacy in NNRTI-na ve, treatment-experienced patients. Efavirenz has demonstrated superiority over nelfinavir in nucleoside-experienced patients, although combining these 2 agents may represent the best approach in these circumstances. The tolerability of NNRTIs appears generally good with few individuals discontinuing in clinical studies as a result of adverse drug events.

Either single (170 mg/kg) or repeated (75 mg/kg per day for 5 days) oral administration of cypermethrin was found to produce significant oxidative stress in cerebral and hepatic tissues of rats, as was evident by the elevation of the level of thiobarbituric acid reactive substances (TBARS) in both tissues, either 4 or 24 h after treatment. Much higher changes were observed in liver, increasing from a level of 60% at 4 h up to nearly 4 times the control at 24 h for single dose. Reduced levels (up to 20%) of total glutathione (total GSH), and elevation of conjugated dienes ( approximately 60% in liver by single dose at 4 h) also indicated the presence of an oxidative insult. Glutathione-S-transferase (GST) activity, however, did not differ from control values for any dose or at any time point in cerebral and hepatic tissues. Pretreatment of rats with allopurinol (100 mg/kg, ip) or Vitamin E (100 mg/kg per day, ig, for 3 days and a dose of 40 mg/kg on the 4th day) provided significant protection against the elevation of TBARS levels in cerebral and hepatic tissues, induced by single high dose of oral cypermethrin administration within 4 h. Thus, the results suggest that cypermethrin exposure of rats results in free radical-mediated tissue damage, as indicated by elevated cerebral and hepatic lipid peroxidation, which was prevented by allopurinol and Vitamin E." ], "offsets": [ [ 0, 1731 ] ] } ]

The growth of Pseudomonas aeruginosa, particularly serotype O11, in pentazocine and tripelennamine was evaluated as a possible explanation for the association of deep-seated infection with this organism and abuse of these drugs. The mean reduction of growth caused by the drugs was 1,000-fold greater for 49 Pseudomonas strains from normal subjects than for 32 strains from drug addicts (4.2 vs. 1.3 logs of reduction at 2 hr, P less than .0005). A common phenotypic subset of the serotype O11 strains from drug addicts was especially resistant to the inhibitory effects. Twelve strains of Staphylococcus aureus (a frequent cause of infection in heroin, but not in pentazocine and tripelennamine, addicts) were completely inhibited by the drug combination. Dose-response curves (derived from the results of using the tablets as well as pure powders) showed that tripelennamine was responsible for the inhibitory activity, which was partially antagonized by pentazocine. We conclude that an ability of some P. aeruginosa serotype O11 strains, but not S. aureus, to survive in pentazocine and tripelennamine may explain in part a shift from S. aureus to P. aeruginosa as common pathogens of drug addicts in areas where abuse of this combination of drugs has increased." ], "offsets": [ [ 0, 1377 ] ] } ]

On the other hand, surprisingly, green tea gallocatechins, (-)-epigallocatechin-3-O-gallate and theasinensin A, potently enhanced the promoter activity (182 and 247% activity at 1 microM, respectively). The regulation of the level of the glucocorticoid-induced gene expression by the antioxidative gallates is of great interest from a therapeutic point of view." ], "offsets": [ [ 0, 1179 ] ] } ]

Powder x-ray diffraction, differential scanning calorimetry, differential thermal analysis, and scanning electron microscopy were used to characterize the aerosol particles and starting material.

The homodimeric disintegrin contortrostatin was compared directly to the monomeric disintegrins echistatin and flavoridin for the ability to affect protein tyrosine phosphorylation in tumor cells. It was observed that contortrostatin had a dramatic effect on the tyrosine phosphorylation status of several proteins in T24 human bladder cancer cells, including robust induction of phosphorylation of proteins in the range of 120-140 kDa. Echistatin alone had no effect on tyrosine phosphorylation in T24 cells, but dose-dependently inhibits the effects of contortrostatin when both are added simultaneously. Among the proteins that undergo tyrosine phosphorylation in response to contortrostatin treatment is CAS, a 130 kDa adapter protein involved in integrin signaling. Flavoridin alone was found to have no effect on CAS, but can completely block contortrostatin-induced phosphorylation of this protein in MDA-MB-435 cells.

Clostridium difficile toxin A displays both cytotoxic and enterotoxic activities. It has recently been demonstrated that toxin A exerts its cytotoxic effect by the glucosylation of the small GTP-binding proteins of the Rho family. Diethyl pyrocarbonate, at pH 7.0, was used to chemically modify exposed histidine residues on toxin A. Modification of toxin A with diethyl pyrocarbonate abolished both its cytotoxic activity and the ability of the toxin to bind Zn-Sepharose gel. Treatment of toxin A with [(14)C]-diethyl pyrocarbonate revealed concentration dependent labelling of histidine residues on the toxin molecules. The effects of diethyl pyrocarbonate could be reversed by hydroxylamine treatment. These data suggest the modified histidine residues on toxin A are critical to its cytotoxic activity. Histidine modification had no effect on the glucosyl transferase enzyme activity of toxin A. However, modification abolished the 'cold' binding of toxin to bovine thyroglobulin in an ELISA and reduced ligand binding activity in a rabbit erythrocyte haemagglutination assay. The data suggest that the histidine residues may be crucial to the receptor-binding activity of toxin A.

METHODS: We carried out two different 3-way crossover studies in healthy subjects (each, n = 9). In study one, hyperglycaemic clamps (5.6 mmol/l, 11.1 mmol/ 1, 16.7 mmol/l) were carried out during placebo or insulin (dose 1: 1 mU/kg/min; dose 2: 2 mU/kg/min) infusion. The second study was identical but endogenous insulin secretion was blocked with somatostatin. The renal plasma flow, glomerular filtration rate and pulsatile choroidal blood flow were measured using the paraaminohippurate method, the inulin method and a laser interferometric measurement of fundus pulsation amplitude, respectively. RESULTS: Insulin increased renal plasma flow and fundus pulsation amplitude but not the glomerular filtration rate. Hyperglycaemia increased all the renal and ocular parameters studied. Haemodynamic effects of glucose and insulin were additive when somatostatin was co-administered but not under basal conditions. CONCLUSIONS/INTERPRETATION: Glucose and insulin can exert additive vasodilator properties on renal and ocular circulation. To find out whether this observation is related to the increased regional perfusion in diabetes longitudinal studies on patients with Type I (insulin-dependent) diabetes mellitus are needed." ], "offsets": [ [ 0, 1599 ] ] } ]

Slow chylomicron intravascular catabolism has been associated with coronary artery disease and screening for drugs that can speed-up this process can be important. In this study, the effects of etofibrate upon chylomicron metabolism was tested by determination of the plasma kinetics of a chylomicron-like emulsion model in 12 patients with coronary artery disease, aged 59+/-11 years, (total cholesterol: 240+/-41 mg/dl; triglycerides: 188+/-42 mg/dl) submitted to a randomized, crossover, double-blind, placebo-controlled study with administration of 1 g per day etofibrate or placebo for 1-month. A 1-month washout period was inserted between the treatment periods. Patients were intravenously injected a chylomicron-like emulsion doubly labeled with 14C-cholesteryl oleate and 3H-triolein at baseline and after treatments. After etofibrate treatment, there was decrease of total cholesterol and triglyceride plasma levels and a trend to increase high-density lipoprotein cholesterol plasma levels. Etofibrate elicited 62% enhancement of post-heparin lipolytic activity and 100% increase of 3H-triglyceride fractional clearance rate compared with placebo treatment. 14C-cholesterol ester fractional clearance rate was 260% greater after etofibrate than after placebo.

OBJECTIVE: Our objective was to characterize the steady-state pharmacokinetics of everolimus and cyclosporine (INN, ciclosporin) when coadministered in de novo kidney allograft recipients during the first year after transplantation. METHOD: This study was a multicenter randomized double-blind study of 101 patients who were randomly assigned 1:1:1 to receive everolimus tablets at doses of 0.5 mg, 1 mg, or 2 mg twice daily with cyclosporine and prednisone. Blood sampling for the pharmacokinetics of everolimus and cyclosporine was performed on day 1, on weeks 1, 2, 3, and 4, and on months 2, 3, 6, 9, and 12. Everolimus dose-proportionality and stability over time were assessed in the context of linear regression and ANOVA models. Everolimus exposure-response relationships between area under the blood concentration-time curve (AUC) and changes in platelets, leukocytes, and lipids were explored with the median-effect model. Potential differences in cyclosporine dosing and pharmacokinetics at different levels of everolimus exposure were assessed in the context of ANOVA. RESULTS: Everolimus steady state was reached on or before day 7, with a median 3-fold accumulation of drug exposure compared with that after the first postoperative dose. Both steady-state maximum concentration and AUC were dose proportional over the full dose range when assessed on day 1, as well as for the full duration of the study at steady state. There was evidence for longitudinal stability in AUC of everolimus during the course of the study. The interindividual pharmacokinetic variability for AUC was 85.4% and intraindividual, interoccasion variability was 40.8%. Age (range, 17-69 years), weight (range, 49-106 kg), and sex (65 men and 36 women) were not significant contributors to variability. There was an increasing incidence of transient thrombocytopenia (or =100 x 10(9)/L) with increasing everolimus AUC (P = .03). Cyclosporine doses, trough concentrations, and AUC exhibited similar temporal patterns during the course of the study regardless of the co-administered everolimus dose level (P = .13, .82, and .76, respectively). CONCLUSIONS: Everolimus exhibited dose-proportional, stable exposure during the first post-transplant year.

Electrophilic agents--a class of chemicals that includes most genotoxic compounds--can be inactivated by reaction with glutathione or other SH-bearing molecules. The conjugates so formed often appear in the urine as mercapturic acids or other thioether products. This paper critically reviews the suitability of the urinary thioether assay as a method for the detection of exposure to electrophilic agents or their precursors. In practice, the greatest value of the thioether assay appears to lie in its signal function. This is demonstrated for cigarette smokers and industrial workers involved in chemical waste incineration. Whenever increased thioether excretion is observed, it is likely to be due to exposure to one or more suspect compounds. However, when the thioether concentration ranges within the limits of the normal value, one must not conclude that there is no, or negligible, exposure.

In contrast, nucleophosmin/B23 in serum-deprived ras-transformed (RAS-3T3) cells was as stable as that in serum-supplemented NIH-3T3 or RAS-3T3 cells. Treatment of RAS-3T3 cells with nucleophosmin/B23 antisense oligomer significantly potentiated the apoptosis induced by serum deprivation. Much less caspase-3 activity was noted in the lysate derived from serum-deprived RAS-3T3 cells compared with that in the lysate of serum-deprived NIH-3T3 cells. Cell permeable caspase-3 inhibitor added in the medium blocked the decrease of nucleophosmin/B23 and apoptosis induced by serum deprivation in NIH-3T3 cells. The inhibitor, on the other hand, promoted significant decrease of nucleolin/C23 in NIH-3T3 cells during serum deprivation. Unlike nucleolin/C23, down-regulation of nucleophosmin/B23 was thus not proliferation-dependent but caspase-3- and apoptosis-dependent.

Available data indicate that platelet function and arachidonic acid metabolism are important factors in hemostasis and regulation of vascular tone.

Release of arachidonic acid from membrane phospholipids as well as subsequent synthesis and release of vasoconstrictor thromboxane A2 are also regulated by movement of calcium ions. Adenosine 3':5'-cyclic phosphate in turn controls levels of free calcium ions in platelets and regulates calcium-dependent reactions. Slow-channel calcium blockers, such as verapamil, diltiazem and nifedipine, inhibit platelet activation in vitro, and decrease platelet adhesion intravascularly. These agents have also been shown to decrease platelet nucleotide release and thromboxane A2 generation. Some preliminary data suggest that calcium blockers also increase generation of vasodilator and platelet antiaggregant prostacyclin, which could contribute to decrease in platelet function.

Animals studies on the various dual-memory theories have been carried out mainly on the basis of hippocampal system function. Specifically, they have focused on aspects of learning and memory that are impaired (vs. spared) by lesions of the hippocampal formation. However, there are several instances in the animal literature showing that hippocampal lesions actually produced enhanced learning and memory function. Moreover, the acquisition of tasks that are facilitated by hippocampal lesions (or dysfunction) is nevertheless associated, in intact subjects, with specific neurobiological alterations in the hippocampus. This problem has been analysed using two different tasks in mice: a bar-press conditioning and a spatial discrimination task. Results showed that, depending on the task considered, the same pharmacological treatment produced either a facilitation or an impairment of acquisition. Moreover, each task induced significant alterations in hippocampal adenylate cyclase activity but in opposite directions. Together with previous findings, these results suggest that the hippocampus is involved in both the so-called \"hippocampal-dependent\" \"hippocampal-independent\" forms of memory. It is postulated that some of the observed training-induced neurobiological alterations might reflect the interaction between two (or more) competing memory systems at the hippocampal level. Thus, in addition to its proposed specific information processing functions (i.e., relational), the hippocampus would play a role in addressing information to the brain memory system that, in a given situation, has the best adaptive value.(ABSTRACT TRUNCATED AT 250 WORDS)" ], "offsets": [ [ 0, 1888 ] ] } ]

Type 2 diabetes mellitus is a growing problem not only in the United States but also across the world. There is now strong evidence that intensive control of blood glucose can significantly reduce and retard the microvascular complications of retinopathy, nephropathy, and neuropathy. Ultimately however, up to 80% of type 2 diabetics die from macrovascular cardiovascular disease. This increased incidence of atherosclerotic disease is intricately associated with insulin resistance, which is a major pathophysiologic abnormality in type 2 diabetes. There is strong evidence that insulin resistance is involved in the development of not only hyperglycemia, but also dyslipidemia, hypertension, hypercoagulation, vasculopathy, and ultimately atherosclerotic cardiovascular disease. This cluster of metabolic abnormalities has been termed the insulin resistance or cardiovascular dysmetabolic syndrome. The thiazolidinediones (rosiglitazone and pioglitazone), a new class of oral antidiabetic agents, are \"insulin sensitizers\" and exert direct effects on the mechanisms of insulin resistance. These effects not only improve insulin sensitivity and glycemic control with reduced insulin requirements, but also have potentially favorable effects on other components of the cardiovascular dysmetabolic syndrome. Long-term studies are needed to determine whether the insulin-sensitizing effects of the glitazones can prevent or delay premature atherosclerotic cardiovascular disease, morbidity, and death." ], "offsets": [ [ 0, 1588 ] ] } ]

METHODS: From the beginning of the experiment, rats were given 10 weekly subcutaneous injections of AOM (7.4 mg/kg body weight) and subcutaneous injections of bombesin (40 microg/kg body weight) every other day, and from week 16, intraperitoneal injections of verapamil (10 or 20 mg/kg body weight) every other day until the end fo the experiment in week 45. RESULTS: Bombesin significantly increased the incidence of intestinal tumors and cancer metastasis to the peritoneum. Although verapamil administered at either dose had little or no effect on the enhancement of intestinal carcinogenesis by bombesin or on the location, histologic type, depth of involvement, labeling index, apoptotic index or tumor vascularity of intestinal cancers, it significantly decreased the incidence of cancer metastasis.

Phencyclidine (PCP) produces psychotomimetic effects in humans that resemble schizophrenia symptoms. In an effort to screen compounds for antipsychotic activity, preclinical researchers have investigated whether these compounds block PCP-induced behaviors in animals. In the present study, the atypical antipsychotic clozapine was tested in combination with an active dose of PCP in two-lever drug discrimination and mixed signalled-unsignalled differential-reinforcement-of-low-rates (DRL) procedures. PCP produced distinctive effects in each task: it substituted for the training dose in PCP discrimination and it increased the number of responses with short (<3 s) interresponse times as well as increasing overall response rates in the DRL schedule. Acute dosing with clozapine failed to alter the behavioral effects of PCP in either procedure even when tested up to doses that produced pharmacological effects alone. These results suggest that acute dosing with clozapine would not affect behaviors most closely associated with PCP intoxication. Further, they bring into question the utility of using PCP combination procedures in animals to screen for antipsychotic potential. Since chronic dosing is required for therapeutic efficacy of antipsychotics, future studies should focus on investigation of chronic dosing effects of these drugs in combination with PCP." ], "offsets": [ [ 0, 1481 ] ] } ]

[ { "id": "11180036__text", "type": "abstract", "text": [ "Pharmacokinetic interaction between single oral doses of diltiazem and sirolimus in healthy volunteers. AIM AND BACKGROUND: The pharmacokinetic interaction between sirolimus, a macrolide immunosuppressant metabolized by CYP3A4, and the calcium channel blocker diltiazem was studied in 18 healthy subjects. Several clinically important interactions have previously been reported for other immunosuppressive drugs that are metabolized by the same enzyme and for calcium antagonists. METHODS: Healthy subjects who were 20 to 43 years old participated in an open, three-period, randomized, crossover study of the pharmacokinetics of a single 10-mg oral dose of sirolimus, a single oral 120-mg dose of diltiazem, and the two drugs given together. The three study periods were separated by a 21-day washout phase. RESULTS: The geometric mean (90% confidence interval) whole blood sirolimus area under the plasma concentration time-curve increased 60% (35%-90%), from 736 to 1178 ng x h/mL, and maximum concentration increased 43% (14%-81%), from 67 to 96 ng/mL, with diltiazem coadministration, whereas the mean elimination half-life of sirolimus decreased slightly, from 79 to 67 hours. Apparent oral clearance and volume of distribution of sirolimus decreased with 38% and 45%, respectively, when sirolimus was given with diltiazem. The plasma maximum concentration and area under the plasma concentration-time curve of diltiazem, desacetyldiltiazem, and desmethyldiltiazem were unchanged after coadministration of sirolimus, and no potentiation of the effects of diltiazem on diastolic or systolic blood pressure or on the electrocardiographic parameters was seen. CONCLUSIONS: Single-dose diltiazem coadministration leads to higher sirolimus exposure, presumably by inhibition of the first-pass metabolism of sirolimus. Because of the pronounced intersubject variability in the extent of the sirolimus-diltiazem interaction, whole blood sirolimus concentrations should be monitored closely in patients treated with the two drugs." ], "offsets": [ [ 0, 2027 ] ] } ]

To study the pancreatic effects of other agents, dynamic insulin and glucagon release was measured from the in vitro perfused pancreases of normal and diabetic Chinese hamsters in response to various combinations of arginine (20mM), glucose (100 or 150 mg. per 100 ml.), and theophylline (10 mM). Theophylline alone caused identical insulin and glucagon release in diabetics and normals. Glucose, alone and in the presence of theophylline, caused subnormal insulin release and less suppression of glucagon release in the diabectics than in the normals. Arginine, in the presence of glucose and theophylline, caused excessive glucagon release but nearly normal insulin release in the diabetics. Arginine, in the absence of glucose or theophylline, caused excessive glucagon release in the diabetics and undetectable insulin release in either diabetics or normals.

Diabetic patients have a 20% higher risk of depression than the general population. Treatment with antidepressant drugs can directly interfere with blood glucose levels or may interact with hypoglycemic agents. The treatment of depression in diabetic patients must take into account variations of glycemic levels at different times and a comparison of the available antidepressant agents is important. In the present study we evaluated the interference of antidepressants with blood glucose levels of diabetic and non-diabetic rats. In a first experiment, male adult Wistar rats were fasted for 12 h. Imipramine (5 mg/kg), moclobemide (30 mg/kg), clonazepam (0.25 mg/kg), fluoxetine (20 mg/kg) sertraline (30 mg/kg) or vehicle was administered. After 30 min, fasting glycemia was measured. An oral glucose overload of 1 ml of a 50% glucose solution was given to rats and blood glucose was determined after 30, 60 and 90 min. Imipramine and clonazepam did not change fasting or overload glycemia. Fluoxetine and moclobemide increased blood glucose at different times after the glucose overload. Sertraline neutralized the increase of glycemia induced by oral glucose overload. In the second experiment, non-diabetic and streptozotocin-induced diabetic rats were fasted, and the same procedures were followed for estimation of glucose tolerance 30 min after glucose overload. Again, sertraline neutralized the increase in glycemia after glucose overload both in diabetic and non-diabetic rats. These data raise the question of whether sertraline is the best choice for prolonged use for diabetic individuals, because of its antihyperglycemic effects. Clonazepam would be useful in cases with potential risk of hypoglycemia." ], "offsets": [ [ 0, 1810 ] ] } ]

Because the nitrosourea CCNU is given exclusively by the oral route in man, we have carried out studies in mice on the antitumour activity, acute toxicity and pharmacokinetics of oral CCNU, either alone or in combination with the chemosensitizer misonidazole. In both plasma and KHT tumour the peak concentration and \"early\" AUC for total nitrosoureas were about 1.4-1.5 fold greater for the oral compared to the i.p. route. These differences were reflected in the roughly twofold greater antitumour activity for the oral route. In contrast, acute toxicity tests showed that oral CCNU was 1.45 times less toxic to normal tissue, although the dose-limiting organ may be different for the two routes. Misonidazole reduced the antitumour activity of oral CCNU by dose modifying factors (DMF) of 0.58-0.71. Similarly, the acute toxicity was also diminished by a DMF of 0.74. Misonidazole has a complex effect on oral CCNU pharmacokinetics. The plasma and tumour total nitrosourea peak concentrations were reduced by 1.5 and 1.7 fold respectively. Misonidazole also reduced the \"early\" nitrosourea AUC, with the extent of the reduction depending on the minimum effective concentration (MEC) chosen. For example, the plasma nitrosourea AUC was reduced by factors of 1.05 and 9.6 for MEC values of 1 and 2 micrograms ml-1 respectively.

Between 1988 and 1993, more than 7,000 patients were diagnosed and treated. Since 1988, it has been noted that incidence of melarsoprol reaction had increased systematically between June and October of each year, indicating strong seasonal variation. In 1992 and 1993, two outbreaks of arsenical reactive encephalopathy (ARE) occurred in the sleeping sickness center of Adjumani. The incidence of ARE suddenly exceeded 10% of the patients treated by melarsoprol during August 1992 and September 1993. The onset of 80% of those \"epidemic\" cases, occurred between the 5th and the 11th day of treatment. Two retrospective studies were conducted in 1992 (75 cases) and in 1993 (51 cases). Among the risk factors studied, two appear to increase the risk of ARE: the prescription of thiabendazole to treat strongyloidiasis during the melarsoprol cure and the bad general clinical conditions of patients. These observations suggest that exogenous co-factors could be involved in the occurrence of ARE. Recommendations were to avoid administration of diffusible anti-helminthic treatment during the cure, and to improve the general conditions of patients before the cure of melarsoprol." ], "offsets": [ [ 0, 1456 ] ] } ]

In the present study, it is proposed that the opioids applied to supraspinal brain sites produced their analgesic effects by the activation of different descending pain inhibitory systems. The blockade of the spinal endorphinergic system by intrathecal naloxone on the production of tail-flick inhibition induced by intraventricular beta-endorphin and morphine was then studied. Intraventricular injection of beta-endorphin and morphine produced an inhibition of the tail-flick response to the heat stimulus in rats. Intrathecal injection of naloxone at doses of 0.4 to 40 micrograms caused a dose-related blockade of the inhibition of the tail-flick response induced by intraventricular injection of beta-endorphin, and a high dose of naloxone (40 micrograms) completely blocked the tail-flick inhibition induced by intraventricular beta-endorphin (16 micrograms). On the other hand, intrathecal naloxone (12-120 micrograms) had only a very weak effect on the tail-flick inhibition induced by intraventricular morphine (40 micrograms). Intraventricular injection of naloxone at doses of 1.2 to 12 micrograms equally antagonized in a dose-dependent manner the tail-flick inhibition induced by intraventricular beta-endorphin and morphine. The results indicate that a spinal naloxone-sensitive endorphinergic system is involved in the production of beta-endorphin but not morphine-induced tail-flick inhibition, and suggest that intraventricular beta-endorphin and morphine elicit their pharmacological actions via the activation of different descending pain inhibitory systems; descending epsilon and mu systems for beta-endorphin and morphine, respectively, are proposed." ], "offsets": [ [ 0, 1820 ] ] } ]

Palytoxin (PTX), C129H223N3O54, isolated from marine coelenterates of Palythoa tuberculosa, caused a first rapid contraction followed by the slow phasic contraction of guinea-pig vas deferens. In the presence of ouabain (10(-5) M), PTX (10(-8) M) failed to cause the first contraction; however, the second contraction was potentiated. In the presence of phentolamine (10(-6) M), the second contraction was inhibited selectively. When ouabain was applied to the muscle in the presence of phentolamine, both first and second contractile responses to PTX were abolished. When the muscle was exposed to the potassium-depleted solution, the first contractile response to PTX was rather potentiated. PTX caused the release of norepinephrine from the muscle. Exposure of the muscle to ouabain (10(-5) M) markedly increased the PTX-induced release. It is indicated that the first and second contractile responses to PTX have entirely different properties. The second response is due to a release of norepinephrine from nerves and was potentiated by ouabain through the increase in the norepinephrine release, whereas the first response was not due to the norepinephrine release but presumably to a direct action on smooth muscle cell and was inhibited by ouabain. The mechanism of the action of PTX was discussed in the relation with Na,K-ATPase." ], "offsets": [ [ 0, 1457 ] ] } ]

The effects of supplementary oral cobalt and iron, as well as the interaction between both at the absorption site, fecal and urinary excretion as well as the retention of these trace elements were determined by using four diets containing either 9 or 63 micrograms/kg of Co and 48 or 446 mg/kg of Fe over a period of 19 days in a total of 24 rats. Retention was calculated by the balance technique and by the comparative slaughter technique. After one day, fecal as well as urinary excretion of both elements had already responded to the dietary treatments, with constant values being reached after approximately three days. Cobalt excretion was enhanced by supplementary cobalt; fecal excretion, too, was increased by supplementary iron; whereas urinary excretion was decreased in both cases. Additional iron significantly inhibited the absorption of cobalt in both dietary cobalt treatments. The lower rate of absorption in the groups receiving 446 mg Fe instead of 48 mg of Fe per kg diet resulted in a decreased renal excretion of cobalt. Consequently, the effect of iron on the retention of cobalt was lower than on absorption. This suggests that interactions between the two elements only take place at the site of absorption. Because of the low dietary cobalt concentration as compared to the iron contents of the diets, no effect of cobalt on iron absorption and excretion occurred. Differences in iron balance were only observed between both dietary concentrations, showing a higher absolute but a lower relative absorption as well as retention in the groups fed further Fe.(ABSTRACT TRUNCATED AT 250 WORDS)" ], "offsets": [ [ 0, 1677 ] ] } ]

Mice from the 20th generation of three lines divergently selected for response to pentobarbital-induced sedation times [long-sedation time (LST), short sedation time (SST), and randomly bred control (RBC)] were used to study cocaine-induced behavioral sensitization. These lines showed variable degrees of locomotor activities in response to cocaine. At a low cocaine dose and long withdrawal period (10 mg/kg, twice a day for 5 days followed by a 14-day withdrawal), the LST mice showed tolerance development. In response to cocaine, the locomotor activities of the SST were not significantly different from the RBC group. At a higher dose and a shorter withdrawal period (20 mg/kg, daily for 7 days followed by a 3-day withdrawal), the SST mice showed behavioral sensitization similar to the RBC mice, but the LST mice did not develop sensitization. The different responses in locomotor activity induced by cocaine suggest that genetic factors may play a role in determining the magnitude of response to this drug. Dopamine (DA) levels did not differ significantly in either striatum (STR) or nucleus accumbens (NAC) for the cocaine-treated animals to their corresponding saline-treated controls. The affinity (Kd) of D2 in the NAC decreased significantly, without changes in density (Bmax), in the cocaine-treated SST and RBC mice. On the other hand, the density of D2 binding sites in the SST and the RBC mice in the STR was significantly increased in cocaine-treated groups without change in Kd. The LST mice did not show any changes in the Kd and Bmax in either the STR or the NAC. Taken together, these findings suggest that the changes in the Kd of D2 in the NAC and the Bmax of D2 in the STR may contribute to the differences in locomotor responses to cocaine exposure in these mouse lines." ], "offsets": [ [ 0, 1921 ] ] } ]

The behavioral effects of the stereoisomers of N-allylnormetazocine (NANM) were compared with those of phencyclidine (PCP) in pigeons and squirrel monkeys responding under a multiple fixed-interval fixed-ratio (FI FR) schedule of food presentation. Intermediate doses of (+)-NANM or PCP produced transient increases in FI responding in monkeys and sustained increases in FI responding in pigeons; higher doses decreased FI and FR responding in both species. In contrast to its enantiomer, (-)-NANM failed to increase FI responding significantly in either species; at high doses, (-)-NANM decreased FI and FR responding. In monkeys, (-)-NANM was about 10 times more potent than (+)-NANM in decreasing responding, whereas in pigeons (-)-NANM was about equipotent with (+)-NANM. In both species, (-)-NANM, but not (+)-NANM, antagonized the rate-decreasing effects of morphine on FI and FR responding. In monkeys, the effects of (-)-NANM, but not (+)-NANM or PCP, were antagonized by naloxone; the doses of naloxone required to antagonize the effects of (-)-NANM were more than 100 times higher than those required to antagonize the effects of morphine. In pigeons, naloxone did not systematically alter the effects of (-)-NANM, (+)-NANM or PCP. Haloperidol reduced or eliminated the increases in FI responding produced by intermediate doses of either (+)-NANM or PCP in pigeons, but did not antagonize the decreases in FI or FR responding produced by high doses of PCP or either stereoisomer of NANM. The results demonstrate a high degree of stereoselectivity in the behavioral effects of NANM.

Interest in administering compounds in combination lies both in enhancing efficacious effects and in limiting adverse effects. Although much statistical work has focused on developing mathematical functions to model the joint dose-response curves, relatively little work exists in regard to designing experiments for assessing joint action. A variety of parametric dose-response models based on either the normal or logistic probability distribution have been proposed in the literature. These models are typically nonlinear in the parameters, and as such, a nonlinear weighted least squares approach can be employed for the purpose of designing experiments. The approach is applicable across a wide variety of settings commonly associated with joint action data, including continuous and discrete responses, alternative error structures, and nonzero background response. Further, designs can be expressed in terms of proportionate responses associated with the individual compounds rather than dose levels, thereby providing for results that are applicable across compounds. As a precursor to this effort, optimal and minimal experimental designs for the case in which a single compound is administered have also been developed. Although the proposed methodology for deriving experimental designs can be applied to any nonlinear regression model, primary focus is given to the additive and nonadditive independent joint action (IJA) models for individual and combined exposures proposed by Barton, Braunberg, and Friedman (1)." ], "offsets": [ [ 0, 1617 ] ] } ]

Acid secretion in isolated rabbit gastric glands was monitored by the accumulation of [(14)C]aminopyrine. Stimulation of the glands with carbachol synergistically augmented the response to dibutyryl cAMP. The augmentation persisted even after carbachol was washed out and was resistant to chelated extracellular Ca(2+) and to inhibitors of either protein kinase C or calmodulin kinase II. Cytochalasin D at 10 microM preferentially blocked the secretory effect of carbachol and its synergism with cAMP, whereas it had no effect on histamine- or cAMP-stimulated acid secretion within 15 min. Cytochalasin D inhibited the carbachol-stimulated intracellular Ca(2+) concentration ([Ca(2+)](i)) increase due to release from the Ca(2+) store. Treatment of the glands with cytochalasin D redistributed type 3 inositol 1,4,5-trisphosphate receptor (the major subtype in the parietal cell) from the fraction containing membranes of large size to the microsomal fraction, suggesting a dissociation of the store from the plasma membrane. These findings suggest that intracellular Ca(2+) release by cholinergic stimulation is critical for determining synergism with cAMP in parietal cell activation and that functional coupling between the Ca(2+) store and the receptor is maintained by actin microfilaments." ], "offsets": [ [ 0, 1384 ] ] } ]

Statistical analysis: Mantel-Haenszel (alpha = 0.05). Patients' mean age was 69.1 (95% CI, +/- 1.2). Mean number of drugs per MAC was 4 (95% CI, +/- 0.2). 341 PI affecting 197 patients (31.5%, 95% CI, +/- 3.6) were identified. 24.9% (95% CI, +/- 4.5) were PICR, detected in 11.7% (95% CI, +/- 2.5) of the MAC.

[ { "id": "7786695__text", "type": "abstract", "text": [ "Magnesium and therapeutics. Two different types of therapy with magnesium are used: physiological oral magnesium supplementation which is totally atoxic since it palliates magnesium deficiencies by simply normalizing the magnesium intake and pharmacological magnesium therapy which may induce toxicity since it creates iatrogenic magnesium overload. Primary and secondary magnesium deficiencies constitute the sole indication of physiological oral magnesium therapy. It is therefore necessary to be well acquainted with the clinical and paraclinical pattern of magnesium deficit and to discriminate between magnesium deficiency due to an insufficient magnesium intake which only requires oral physiological supplementation and magnesium depletion related to a dysregulation of the control mechanisms of magnesium status which requires more or less specific regulation of its causal dysregulation. Physiological oral magnesium load constitutes the best tool for diagnosis of magnesium deficiency and the first step of its treatment. Physiological oral magnesium supplementation (5 mg/kg/day) is easy and can be carried out in the diet or with magnesium salts, with practically only one contra-indication: overt renal failure. Specific and aspecific treatments of magnesium depletion are tricky using for example magnesium sparing diuretics, pharmacological doses of vitamin B6, physiological doses of vitamin D and of selenium. In order to use the pharmacological properties of induced therapeutic hypermagnesaemia, high oral doses of magnesium (> 10 mg/kg/day) are advisable for chronic indications and the parenteral route is suitable for acute indications. There are 3 types of indications: specific (for the treatment of some forms of magnesium deficit i.e. acute), pharmacological (i.e. without alterations of magnesium status) and mixed--pharmacological and aetiopathogenic--(for example complications of chronic alcoholism). Today pharmacological magnesium therapy mainly concerns the obstetrical, cardiological and anaesthesiological fields. The main indications are eclampsia, some dysrhythmias (torsades de pointe particularly) and myocardial ischaemias. But it is now difficult to situate the exact place of the pharmacological indications of magnesium. Magnesium infusions can only be envisaged in intensive care units with careful monitoring of pulse, arterial pressure, deep tendon reflexes, hourly diuresis, electrocardiogram and respiratory recordings. High oral magnesium doses besides their laxative action may bring latent complications which may reduce lifespan. There may remain some indications of the laxative and antacid properties of non soluble magnesium, particularly during intermittent haemodialysis. Lastly local use of the mucocutaneous and cytoprotective properties of magnesium is still valid, in cardioplegic solutions and for preservation of transplants particularly." ], "offsets": [ [ 0, 2901 ] ] } ]

[ { "id": "11219477__text", "type": "abstract", "text": [ "Sildenafil citrate: a therapeutic update. BACKGROUND: Since its approval by the US Food and Drug Administration in March 1998, sildenafil citrate has been used by millions of men for the treatment of erectile dysfunction. Recent studies and consensus reports have expanded our understanding of its efficacy, safety, contraindications, and drug interactions. OBJECTIVE: This paper reviews recent studies of the efficacy of sildenafil, its adverse effects and drug interactions, and socioeconomic factors involved in its use, with a focus on specific patient populations (prostate cancer, diabetes mellitus, ischemic heart disease, spinal cord injuries, neurologic disorders). METHODS: Clinical studies, case reports, and commentaries and editorials concerning sildenafil published in the international literature between January 1999 and August 2000 were identified through searches of MEDLINE, PREMEDLINE, and International Pharmaceutical Abstracts, using the terms sildenafil, Viagra, and erectile dysfunction. RESULTS: Sildenafil has demonstrated effectiveness in men with erectile dysfunction associated with prostatectomy, radiation therapy, diabetes mellitus, certain neurologic disorders, and drug therapy (eg, selective serotonin reuptake inhibitors [SSRIs]). It has not been as effective in women with sexual dysfunction, with the exception of SSRI-associated sexual dysfunction. Some disorders unrelated to sexual dysfunction (eg, esophageal motility dysfunction) may also respond to sildenafil. In the general population, sildenafil is considered to have an acceptable tolerability profile; however, patients with moderate to severe cardiovascular disease or those taking nitrate therapy are at increased risk for potentially serious cardiovascular adverse effects with sildenafil therapy. In addition, patients taking drugs that inhibit the cytochrome P450 3A4 isozyme, which metabolizes sildenafil, may experience increased drug concentrations and possible toxicity from normal doses of sildenafil. CONCLUSIONS: Sildenafil is an effective first-line therapy for erectile dysfunction in men. The decision to prescribe this agent should include such considerations as the cost-risk-benefit balance, patient access, drug distribution pathways, and prescription drug coverage." ], "offsets": [ [ 0, 2284 ] ] } ]

The biochemical toxicology of 1,3-difluoroacetone, a known metabolite of the major ingredient of the pesticide Gliftor (1,3-difluoro-2-propanol), was investigated in vivo and in vitro. Rat kidney homogenates supplemented with coenzyme A, ATP, oxaloacetate, and Mg2+ converted 1,3-difluoroacetone to (-)-erythro-fluorocitrate in vitro. Administration of 1,3-difluoroacetone (100 mg kg(-1) body weight) to rats in vivo resulted in (-)-erythro-fluorocitrate synthesis in the kidney, which was preceded by an elevation in fluoride levels and followed by citrate accumulation. Animals dosed with 1,3-difluoroacetone did not display the 2-3 hour lag phase in either (-)-erythro-fluorocitrate synthesis or in citrate and fluoride accumulation characteristic of animals dosed with 1,3-difluoro-2-propanol. We demonstrate that the conversion of 1,3-difluoro-2-propanol to 1,3-difluoroacetone by an NAD+-dependent oxidation is the rate-limiting step in the synthesis of the toxic product, (-)-erythro-fluorocitrate from 1,3-difluoro-2-propanol. Prior administration of 4-methylpyrazole (90 mg kg(-1) body weight) was shown to prevent the conversion of 1,3-difluoro-2-propanol (100 mg kg(-1) body weight) to (-)-erythro-fluorocitrate in vivo and to eliminate the fluoride and citrate elevations seen in 1,3-difluoro-2-propanol-intoxicated animals. However, administration of 4-methylpyrazole (90 mg kg(-1) body weight) to rats 2 hours prior to 1,3-difluoroacetone (100 mg kg(-1) body weight) was ineffective in preventing (-)-erythro-fluorocitrate synthesis and did not diminish fluoride or citrate accumulation in vivo. We conclude that the prophylactic and antidotal properties of 4-methylpyrazole seen in animals treated with 1,3-difluoro-2-propanol derive from its capacity to inhibit the NAD+-dependent oxidation responsible for converting 1,3-difluoro-2-propanol to 1,3-difluoroacetone in the committed step of the toxic pathway." ], "offsets": [ [ 0, 2043 ] ] } ]

The initiation of alcohol or nicotine use may be precipitated by similar personality characteristics in the user, such as impulsivity and sensation seeking. Moreover, the mechanisms underlying the development of dependence may be similar for alcohol and nicotine. Thus, certain factors, such as reinforcing drug effects, conditioning processes, automatic behavior, and stress, may influence the development of dependence on both drugs.

It is now clear that topoisomerase activity level is an important determinant of sensitivity to topo drugs. The regulation of topoisomerases is no doubt complex and multifaceted and is probably accomplished through redundancy at many control levels. The mechanism(s) of altered topo I expression in certain tumor types is unknown, but may be related to the central importance of topoisomerases in proliferating cell functions (transcription, replication, etc.), and the aberrant and chronic activation of these functions as a result of specific tumorigenic alterations. Small differences in sensitivity to chemotherapy can have a dramatic effect on cure rates, and therefore subtle cell type-specific differences may be important determinants of drug sensitivity. Whether abnormal topoisomerase quantity and specific activity are associated with resistance or sensitivity to topoisomerase-targeted chemotherapy in the clinic is now being studied. Determinants downstream of cleavable complex formation that affect the sensitivity of tumor versus normal cells to topo drugs in particular and DNA-damaging agents in general are little known. The goal of enhancing selective tumor cell killing relative to the normal cells that are dose limiting may be achieved either by overcoming tumor cell resistance or by protecting normal cells.

Although activation of several transcription factor IEGs has been described, little is known about effector IEGs. Here, we have examined whether METH administration affects expression of an effector IEG arc (activity-regulated, cytoskeleton-associated) that encodes a protein with homology to spectrin. Using in situ hybridization, we observed that METH caused a rapid and transient dose-dependent increase in arc mRNA level in the striatum and cortex that was abolished by pretreatment with the specific dopamine D1 receptor antagonist SCH-23390 but not by an atypical neuroleptic clozapine. METH induced arc mRNA in layers IV and VI of the cortex which dopamine receptor are localized to.

Internal application of InsP(3) (100 microM) increased intracellular Ca(2+) concentration ([Ca(2+)](i)) and activated the Ca(2+)-dependent K(+) current.

Pretreatment of megakaryocytes with extracellular RR (50 microM) also inhibited InsP(3)-induced responses. Intracellular and extracellular application of RR reduced ADP-induced increases in [Ca(2+)](i). In contrast, in isolated single pancreatic acinar cells, RR had no effect on InsP(3)-induced responses.

[ { "id": "7798493__text", "type": "abstract", "text": [ "Evidence for reduction of norepinephrine uptake sites in the failing human heart. OBJECTIVES. This study investigated the role of neuronal uptake of norepinephrine (uptake-1) in human heart failure as a local factor for altering concentrations of norepinephrine at the cardiac myocyte membranes. BACKGROUND. Several beta-adrenergic neuroeffector defects occur in heart failure. Whether an alteration in norepinephrine uptake-1 occurs is still unresolved. METHODS. The role of norepinephrine uptake-1 was studied in electrically stimulated (1 Hz, 37 degrees C) human ventricular cardiac preparations and isolated myocardial membranes. RESULTS. The effectiveness of norepinephrine in increasing the force of contraction was decreased in relation to the degree of heart failure. In contrast, the potency of norepinephrine was increased in failing hearts (New York Heart Association functional class IV) in relation to the concentrations producing 50% of the maximal effect (EC50). The EC50 values for isoproterenol, which is not a substrate for norepinephrine uptake-1, were reduced in myocardium in functional classes II to III and IV compared with those in nonfailing myocardium. The uptake inhibitors cocaine and desipramine (3 mumol/liter) potentiated the positive inotropic effects of norepinephrine in nonfailing myocardium (p < 0.05) but not in functional class IV myocardium. Radioligand binding experiments using the uptake inhibitor hydrogen-3 mazindol revealed a significant decrease by approximately 30% in norepinephrine uptake-1 carrier density in functional classes II to III and IV myocardium versus nonfailing myocardium (p < 0.05). CONCLUSIONS. In human heart failure, there is a presynaptic defect in the sympathetic nervous system, leading to reduced uptake-1 activity. This defect in the failing heart can be mimicked by the effects of uptake blocking agents, such as cocaine and desipramine, in the nonfailing heart only. Compromised norepinephrine uptake-1 in functional class IV cannot be further increased by cocaine and desipramine. The pathophysiologic consequences could be an increased synaptic concentration of norepinephrine predisposing to adenylyl cyclase desensitization." ], "offsets": [ [ 0, 2202 ] ] } ]

[ { "id": "2578306__text", "type": "abstract", "text": [ "Tumor phenotype and susceptibility to progression as an expression of subpopulations of initiated murine cells. Currently, it is conceived that a number of events, or hits, are required for the induction of tumors by chemical agents. The first phase of this sequence, initiation, is considered to result from at least one event in the genetic apparatus. Analyses of this sequence, however, usually give little consideration to the nature of the target cell or to the characteristics of the resultant tumors. Vesselinovitch et al. (Cancer Res., 38: 2003-2010, 1978) have reported that a single, small pulse of carcinogen can induce early and numerous liver tumors when administered neonatally to mice with a genetic predisposition to hepatotumorigenesis. In the current study, the nonpredisposed strain C57BL/6N was also shown to be highly susceptible to diethylnitrosamine during the neonatal period. C57BL/6N demonstrated large numbers of two of the three types of liver tumors seen in livers of genetically predisposed mice, one of which required the additional stimulus of dietary phenobarbital for growth. Tumors of more malignant phenotype were demonstrated only in genetically predisposed mice (C57BL/6N X C3H/HeN F1) that received one dose of carcinogen. These findings suggest that the phenotype of a tumor that results from a pulse of a chemical carcinogen may depend upon the target cell. The initiated cells that result from this hit may vary from those that demonstrate very little progression in cell type and may or may not require exogenous enhancement of growth to those that can progress very rapidly to fully malignant behavior. The latter might arise from a hit in a genetically initiated cell, the result of which is a more rapid progression in tumor type." ], "offsets": [ [ 0, 1776 ] ] } ]
