将雄性大鼠分为对照组与白明胶组,饲以20％蛋白质的合成饲料。对照组饲料中含有24％酪蛋白,而白明胶组饲料中含有12％酪蛋白及11％白明胶。饲养一定时日后,全身照射875rad。其主要结果为:(1)照射14天以内,白明胶组活存率高于对照组;(2)白明胶组死亡动物的活存日数较对照组为多;(3)白明胶组的体重下降程度不仅较对照组为低,而且其恢复也较快;(4)白明胶组的某些生化损伤较对照组为轻。我们认为,白明胶对急性辐射损伤有明显防治效果,而且可能与改善胶原蛋白的代谢紊乱的营养效应有关。
Male rats were divided into a control group and a gelatin group and fed a synthetic feed containing 20% protein. The control group contained 24% casein, while the gelatin group contained 12% casein and 11% gelatin. After a certain period of feeding, the body was irradiated with 875 rad. The main results were as follows: (1) Within 14 days of irradiation, the viability of the gelatin group was higher than that of the control group; (2) The days of live animals of the dead group were more than that of the control group; (3) The body weight of the gelatin group The degree of decline was not only lower than that of the control group, but also its recovery was faster. (4) Some biochemical lesions in the white gelatin group were lighter than those in the control group. We believe that gelatin has a significant preventive effect on acute radiation damage and may be related to the nutritional effect of improving the metabolism of collagen.
