[Distribution of radioactive phosphorus (P32) and intensity of ATP metabolism in the cardiac muscle of rats following partial parasympathectomy and physical stress].

ATP turnover as well as incorporation of 32P into various parts of myocardium were studied after left-side vagotomy and physical loading. An increase in 32P incorporation was observed within 5, 10, 30, 105 days after the operation. Physical loading decreased the isotope incorporation into heart tissue of vagotomized and control animals under these conditions. The vagotomy did not alter the ATP content in rat myocardium but increased the turnover of ATP.
