title: [Effect of diet overloaded by fats on the enzyme systems of metabolism in rats].
abstract: The feeding of rats with high-fat diet (a part of fats was 50% of energy value of ration against 20% in control) during 4 weeks increased the level of cytochrome P-450 in the liver and enhanced aniline- and p-nitrophenol hydroxylase activity of CYP2E1 as well as erythromycin N-demethylase activity of CYP3A; the activity of aldehyde dehydrogenase class 3, UDP-glucuronosyl transferase, glutathione-S-transferase and N-acetyl transferase. At the same time, the moderate decrease of indomethacin-O-demethylase of CYP2C both phenolsulfotransferase activity were fixed. The changes of enzymatic activity correlated with activating of processes of gluconeogenesis, glycogenolysis and, especially, ketogenesis. A high-fat diet enhanced reactions of biotransformation of amidopyrine, acetanilide, toluene, sulfadimezine, were catalyzed with CYP2E1, CYP3A and enzymes of conjugation, simultaneously it increased the hepatotoxicity of paracetamol.
