Antioxidants and Survival Time of Mice Exposed to Multiple Sublethal Doses of X-Irradiation. ∗

Summary

Experiments were conducted to determine effects of antioxidants on survival time of mice exposed to multiple sublethal doses of total body x-irradiation. Mixed tocopherols and Santoquin at 0.25% level in the diet, and DPPD at levels of 0.25% or 0.5% of diet had little if any protective effect. Propyl gallate, DBH and BHT at levels of 0.25% or 0.5% of the diet increased survival over that on basal unsupplemented ration.
