title: [The effect of nicotinamide, methionine and alpha-tocopherol on the liver conjugating and mono-oxygenase systems and on lipid peroxidation in hepatosis-hepatitis in rats].
abstract: Four days after a single intragastric injection of CCl4 (5 mg/kg as a 50% oil solution) increased intensity of a chemoluminescence "quick flush" in the hepatic microsomes and blood serum, as well as hepatocyte cytolysis (increased ALT activity) and decreased rate of antipyrine elimination from the blood were recorded in rats. The content of cytochromes P-450 and b5 activity of NADH-cytochrome b5 reductase and cytosol glutathione transferase in the hepatic microsomal fractions reduced in this case. Administration of methionine (200 mg/kg) and its combination with nicotinamide (60 mg/kg) without and, particularly, with additional prescription of vitamin E (150 mg/kg) produced a marked antioxidant and enzyme-normalizing effects in the rats.
