Antitoxic properties of a preparation of glutathione S-transferase.

Abstract

Pretreatment of rats with a preparation of the cationic form of rat liver cytosolic glutathione S-transferase 1-3 h before injection of a dose of N-nitroso-N-diethylamine equivalent to the LD50 of the drug completely protects the animals against the toxic effects of the drug. The mechanism of the protective action of glutathione S-transferase is discussed.
