[Effect of gamma radiation on glucose-6-phosphate dehydrogenase activity in the erythrocytes of healthy persons after submaximal physical exertion].
The authors studied effects of gamma radiation and submaximal physical exercise on G6P-DH activity in healthy men erythrocytes. Twelve men aged 20-22 were examined. They were loaded by physical exercise (at doses of 2 W/kg body weight) for 15 minutes. Erythrocytes were exposed to gamma radiation (500 Gy doses) from 60Co source. The activity of G6P-DH in erythrocytes was estimated by Boehringer-Mannheim test. Gamma radiation at 500 Gy dose was found to inhibit G6P-DH enzymatic activity in erythrocytes both at rest and after submaximal physical exercise. Furthermore, submaximal physical exercise was indicated to increase the G6P-DH activity in irradiated erythrocytes.
