[The display of hormesis in the action of quinoid radiotoxins]

Two hours before irradiation (7.5 Gy) mice were injected with quinoid radiotoxins in concentrations close to those formed in mouse blood after gamma-irradiation with a dose of 10 cGy. This increased the survival rate (from 10-20% to 80%), prevented the radiation-induced weight loss, and increased catalase activity in the liver and blood of exposed animals.
