title: [Action of alpha-tocopherol on the enzymes of the electron transport chains in the liver microsomes of irradiated rats].
abstract: Five days following single whole-body gamma irradiation of rats (8.5 Gy) the rate of NADPH and NADH oxidation, the activity of NADPH-cytochrome P-450 and NADH-cytochrome b5 reductases, and the content of cytochromes P-450 and b5 were found to decrease. The intragastric administration of alpha-tocopherol (100 mg/kg, two times a day) produced a normalizing effect.
