title: [Stabilizing action of alpha-tocopherol in postischemic damage to the hydroxylating system of the endoplasmic reticulum membranes of the rat liver].
abstract: Administration of alpha-tocopherol (50 mg/kg) as an oily emulsion into male rat stomach every 12 hours 2 days before and 3 days after local disturbance in liver circulation prevents postischemia (72 hours after resumption of circulation) repression of amidopyrine-N-demethylation, aniline-hydroxylation, NADP H-neotetrazolium reductase, NADP H oxidase, a decrease in the cytochrome P-450 level, as well as intensification of ascorbate-dependent lipid peroxidation of hepatocyte endoplasmic reticulum membranes. The protective effect of alpha-tocopherol is suggested to be due to its antioxidative and membrane-stabilizing properties.
