[Effect of gamma radiation on levels of adenine nucleotides in erythrocytes of healthy individuals after submaximum physical exertion].

The authors studied the effect of gamma radiation and submaximum physical exercise on adenosine-5'-triphosphate (ATP), adenosine-5'-diphosphate (ADP) and adenosine-5'-monophosphate (AMP) contents in erythrocytes of healthy males. Twenty one men aged 20-22 years were examined. They underwent physical exercise at doses of 2 w/kg body weight for 15 min. Erythrocytes were exposed to gamma radiation (500 gy doses) from 60Co source. The concentration of adenine nucleotides in erythrocytes was measured by the Boehringer Mannheim tests. The submaximum physical exercise was found to decrease ATP content and to to increase ADP and AMP in erythrocytes. Gamma radiation at 500 Gy dose was found to decrease ATP concentration in erythrocytes both at rest and after submaximum exercise and to increase AD content. It was revealed that AMP content increased at rest and decreased after submaximum exercise in irradiated erythrocytes.
