The distribution of phenylethanolamine-N-methyltransferase (PNMT), the epinephrine-forming enzyme in the adult rat heart atria and ventricles was studied. The activity of the enzyme in the hearts of adult rats is very low; a significantly higher activity was found in the atria than in the ventricles. A significant increase in PNMT activity was found in all heart areas examined in 6-hydroxydopamine-treated rats compared to vehicle-treated rats. The increased PNMT activity might reflect compensatory or adaptation processes secondary to the destruction of the peripheral sympathetic nerve terminals.
