[ATP metabolism under conditions of radiation injury and the ways of its modification].

Content, methylation and an intensity of restoration of phosphoric components of ATP were studied in cross-striated muscles, brain and liver tissue of normal animals. These patterns were also studied in animals, subjected to irradiation: within 3 hrs after X-ray treatment (800 r); with subcutaneous administration of prozerine (0.5 mcg/kg) and nicotinic acid (20 microng/) 4 hrs before decapitation; and also in animals with vagus, cut off at the level of neck two weeks before irradiation. In different experimental conditions the character of regularity and interrelation between methylation and phosphorylation of ATP were established.
