Abstract:
One hundred adult male rats were equally distributed into 5 groups entitled to recieve protein diets, namely milk-egg, egg, gelatin-corn, beef and soybean cake.Having received these diets for 2 weeks, all rats were given first exposure of 550 rad and fed on the same diet as before. After 30 days, any rat survived in 5 groups had to receive second irradiation of 650 rad.After the first irradiation, the body weights of rats in 5 groups were declined but restored to pre-irradiation level at the 25th day, among them the egg diet group was restored much better. At the same day after the second irradiation, the body weight of the gelatin-corn group restored much more than the soybean, group.No statistically different results have been found in survival rate of 5 groups following the irradiation of 550 rad for 32 days. The survival rate of the gelatin group was higher than that of the soybean group both 32 and 50 days after the second exposure of ?-rays for 650 rad, but the survival rate of the egg diet group was significantly higher only at 50 days.
