title: [Increase in radiation resistance of an organism after administration of metabolic drug MR-33].
abstract: Original MP-33 metabolic drug has inductive action on intracellular levels of glutathione (GSH) and GSH-related enzymes (glutathione peroxidase-GPx, glutathione S-transferase-GST) of animals and human (liver, heart, erythrocytes). Treatment of Wistar male rats with MP-33 per os (6 mg/kg) 30 min before gamma-irradiation with a dose of 7 Gy results in 35% survival and increasing of mean life. In "mother-foetus" system the induction of intracellular level of GSH, GST and GPx by MP-33 leads to enhancement of foetus radioresistance. In contrast to MP-33 us of GSH (6 and 100 mg/kg) is not effective. Perspective of MP-33 us in relation to radioecological crisis is discussed.
