[Vitamin metabolism in rats in the early period after a single whole-body gamma irradiation].

A single whole-body gamma irradiation (4 Gy) of rats with the initial deficiency in vitamins B1 and B2 had no effect on the contents of vitamins C, A, and B1 in the blood plasma, liver, or testicles within 42 h after irradiation. The content of vitamin E remained unchanged in the blood plasma but increased in testicles. The contents of vitamin B2 remained unchanged in erythrocytes and liver, decreased in testicles, and its excretion with urine increased more than twice. The content of reduced glutathione in liver, small intestine mucosa, and erythrocytes decreased.
