Influence of Lyophilized Amaranthus retroflexus Extract on Radioresistance of Laboratory Mice after Single X-Ray Exposure.

Radioprotective therapeutic effect of lyophilized extract ofAmaranthus retroflexus on the resistance of the albino laboratory male mice exposed to X-ray radiation at a one-time dose of LD(100/30) is studied. It was established that a 30-day use of a lyophilized extract of the vegetative parts of A. retroflexus at a dose of 50 mg/kg after X-ray exposure increases the survival rate of mice by 80%, enhances the recovery in the radiation period of the number of leukocytes, neutrophils, lymphocytes in the peripheral blood of the animals and the normalization of the intensity of peroxide oxidation of lipids in liver cells. Dose modification factor on the 5th day after irradiation, when using a lyophilized extract, was 1.5 according to the criterion of survival of mice.
