[Enhanced body radioresistance resulting from the transfusion of autologous blood irradiated with low doses of ionizing radiation].

Abstract

Preliminary administration of autogenic blood irradiated in vitro with ionizing radiation in small doses of 0.05, 0.3 or 0.5 Gy resulted in a pronounced increase in the radioresistance of mice [correction of rats] subsequently irradiated in a dose of 9 Gy. The optimum was autotransfusion of blood irradiated in a dose of 0.3 Gy a day or 10 days prior to the total irradiation which increased the survival rate of experimental animals to 80% while, in control groups, the survival rate was only 10%.
