Prepulse inhibition (PPI), a measure of sensorimotor gating impaired in patients with schizophrenia, is more sensitive to disruption by apomorphine in prepubertal August Copenhagen Irish (ACI) than Sprague-Dawley (SD) rats. In brain regions including

Excess production of H2O2 has been implicated in oncogenesis. The object of the present study was twofold: first, to determine the influence of chronic estradiol (E2) on the activities of selected hepatic antioxidant enzymes in female ACI rats, a str

The effects of sodium cyanide (NaCN) were investigated on the contractile and electrophysiological properties of rat diaphragm muscles in vitro. Sodium cyanide (0.1-1.0 mM) produced an initial potentiation of directly elicited twitch tensions, follow

The aromatic retinoid, (E)-4-[2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthylenyl)-1 -propenyl] benzoic acid (TTNPB) is 1000-fold more teratogenic than all trans-retinoic acid (tRA) in several species. Factors that partially explain the potency

Microsomal triglyceride transfer protein (MTP) plays a central role in the assembly and secretion of apoB-containing lipoproteins. In this study, we investigated the effect of ethanol on the expression of the large subunit of MTP in a human liver hep

The toxicity of allyl alcohol was compared in freshly isolated and cryopreserved hepatocytes that were either placed in suspension or maintained on hydrated collagen gels in a sandwich configuration. The purpose of this study was to evaluate whether

The so-called “reverse metabolism” technique for analysis of polycyclic aromatic hydrocarbon (PAH) metabolites through HI reduction to parent PAH fails for B[a]P. Most of the urinary metabolites of B[a]P are mercapturates. HCl hydrolysis of these

This study shows that 1-hydroxybenzo[ a ]pyrene glucuronide and 1-hydroxybenzo[ a ]pyrene sulfate are formed in isolated rat hepatocytes. Formation of these conjugates by hepatocytes incubated with 1-acetoxy-[G- 3 H]benzo[ a ]pyrene (100 μM) as a so

Marked changes in rates of drug metabolism occur during adolescence; however, biochemical events underlying alterations in drug metabolism in whole hepatocytes during this period of development are not well established. Accordingly, metabolism of 7-e
