肝粉、卷心菜与酵母对急性放射损伤的防护效应

用鸡蛋蛋白粉、蔗糖、植物油、混合盐与维生素配成的饲料作为对照,并分别用肝粉、卷心菜及酵母取代对照饲料中鸡蛋蛋白用量,蔗糖亦相应减少,配成三种实验饲料,饲喂4组大鼠。全身一次照射630伦。实验期为30天。结果表明,三种实验饲料组的死亡率显著地低于对照组。

PROTECTIVE EFFECT OF LIVER, CABBAGE AND YEASTON RADIATION DAMAGE

Rats were divided into 4 groups. Among them the control group was fed to the synthetic diet consisted of egg white powder, sucrose, plant oil, vitamins and salts mixture, the other 3 groups being fed to the same diet except that instead of egg white and sucrose in 20 % composition of diet liver, cabbage and yeast were used respectively.After the irradiation of 630 r, the 30 days mortality in control group was significantly higher than any other experimental group. As compared with the control group, the liver-fed group had longer survival time and more increment of body weight in the recovery period. It suggested that certain factors might exist in liver, cabbage or yeast for the protective effect on acute radiation damage though the action of known nutrients (especially essential trace elements) was not completely exclusive.
