Effect of gamma-radiation on the content of vitamin E in rats

The dynamics of vitamin E dose-dependence in the blood serum of Vistar line male rats after the total single irradiation with 60Co gamma-quantums in 0.2; 0.5; 1.0; 3.0 and 5.0 Gy doses (during 120 days); 7.0 Gy (during 20 days); 9.0 Gy (during 15 days) were studied. The vitamin E content values both in the norm and in 0.5, 1, 2, 4, 6, 8, 10, 15, 20, 30, 45, 65, 90 and 120 days after irradiation are given. The experiment data show that the dose dependence of vitamin E products has wavelike character. The possible causes of the vitamin E level decrease under intake of small and high doses of gamma-irradiation are discussed.
