title: [Effect of alpha-tocopherol on the activity of the liver glutathione antioxidative system and the activity of serum aminotransferase in rats during tetrachloromethane poisoning].
abstract: The activities of glutathione peroxidase, glutathione reductase in the liver as well as of glutamate-pyruvate, and glutamate-oxaloacetate transaminase in blood serum were studied in rats which were injected tetrachloromethane in a dose of 1.04 mmol per 100 g mass for seven days. Tetrachloromethane poisoning is accompanied by a considerable decrease in the glutathione peroxidase activity in the liver and an increase in the aminotransferase activity in the blood serum. Additional administration of 20 and 30 mg of L-tocopherol per 100 g of mass prevents a tetrachloromethane-induced decrease in the activity of glutathione peroxidase in the liver and somewhat normalizes the activity of glutamate-pyruvate and glutamate-oxaloacetate transaminase in the blood serum. Possible mechanisms of the alpha-tocoferol protective action are under discussion.
