Effect of Protein and Amino acid Nutrition on Radiation Damage in Mice (1)

Effect of Dietary Protein Nutrition on Survival of Mice exposed to Total-body γ-irradiation

Abstract

Male dd-weanling mice were fed on 18% casein diet and on 6% casein diet for two or three weeks. The survival rates of mice exposed to a single sublethal dose of total body γ-irradiation (1, 000 R) were observed.
The deficiency in protein before irradiation lowered the survival rates of mice. But the decrease in survival rates could be overcome remarkably by the supplement of adequate protein immediately after irradiation. However, addition of excess amount of protein showed an unfavourable influence.
