Contents of cytochrome P-450 and b5, rates of oxidation of aniline, amidopyrine and dimethylaniline as well as activities of NADP-H- and ascorbate-dependent systems of lipid peroxidation (LPO) in rat liver microsomes five months after single administration of the mixture of polychlorinated diphenyls (PCD) significantly exceeded the control level. Starvation(More)
Single oral administration of sovol (mixture of polychlorinated diphenyls) caused a significant induction of the liver monooxygenase system (MOS) in rats. The inducing effect persisted for 5 months. Liver MOS responses were similar in repeated and primary sovol administrations. Differences in the morphological liver changes have been detected following(More)
A single administration of increasing doses of dichlorodiphenyl (60-2400 mg/kg) leads to an increase in the content of cytochrome P-450 in rat liver. Initially, the increase rate is high whereupon, within the dose ranges of 800-1600 mg/kg, it does not virtually change, constituting 270-290%. A higher dose, 2400 mg/kg, produces an increase in the hemoprotein(More)
Chronic alcohol intoxication led to an increase in activity of alcohol dehydrogenase and to decrease -- of aldehyde dehydrogenase and the microsomal ethanol oxidizing system (MEOS) with simultaneous activation of cytochrome P-450 in liver tissue of rats during ontogenesis. Ethanol, which did not affect the enzymatic status of lysosomes within ontogenesis(More)
We studied the activity of NADPH-cytochrome P-450 reductase, NADPH- and ascorbate-dependent systems of lipid peroxidation in liver microsomes, the activity of superoxide dismutase in the supernatant and the level of malonic acid dialdehyde in liver tissue of rats of various age. The activity of lipid peroxidation system and the malonic dialdehyde content in(More)
The authors have studied the character of changes in the content of cytochrome P450 and b5, in the oxidation rate of amidopyrine, dimethyl-aniline and aniline, in the NADPH- and ascorbate-dependent lipid peroxidation systems, as well as in glucose-6-phosphatase and acetylesterase activities in the liver microsomes of the rats on semisynthetic diets,(More)
