resistance of the weanling rat to acetaminophen (ap ap)-induced hepatotoxicity is manifested with regard to a surge in apap-glutathione (osh) conjugate formation in the liver [allameh et al. mech aging dev 95(1997)71]. the present study was conducted to assess the role of this detoxification pathway in apapinduced lipid per6xidationin the liver. lipid peroxidation measured as thiobarbituric aci...

In vitro transformation of rat fibroblasts by the SCHMIDT-RUPPIN strain of Rous sarcoma virus is described. Primary rat embryo fibroblasts were transformed in 2 to 6 weeks after infection with the virus. The transformed cells were large, refractile and polygonal in appearance and produced multilayer colonies. Injection of the transformed cells to young and weanling Sprague-Dawley rats induced f...

The interrelationships among plasma renin activity (PRA, ng AJ/ml plasma/hr), aldosterone concentration (ng%), and renal Na+-K+-ATPase activity (J.lmole P04/mg protein/ hr) were studied in 9 weanling normotensive spontaneously hypertensive rats (SHR), 9 adult hypertensive SHR, and 9 weanling and 9 adult normotensive Wistar-Kyoto rats (WKY). All groups were placed on a normal (0.4% sodium) diet....

Biotransformation of benzo[a]pyrene (BaP) in the presence of microsomal fractions derived from liver and epiderm of adult and weanling rats was examined. The aim of this study was to evaluate the effect of age on the capacity of two organs in transformation of BaP. Subcellular fractions were prepared from skin and liver by ultracentrifugation and were used as the source of BaP metabolizing enzy...

It has been reported that hamster liver preparations are more effective for the metabolic activation of N-nitrosodimethylamine (NDMA) to a mutagen than rat liver preparations. The enzymatic basis for this phenomenon, however, has not been clearly elucidated. The present study was undertaken to examine the enzymology of NDMA metabolism by different hepatic subcellular fractions prepared from ham...

Female weanling rats received small (1 mAmp for 5 sec) electrolytic lesions in the paraventricular nuclei. Sham-operated rats served as controls. The rats were maintained for 42 days and body weight, linear growth, Lee Index, food intake and efficiency of food utilization were determined throughout the study. Plasma glucose, glycerol, free fatty acids, total protein and carcass fat and protein ...
