Transplantation of xenogenic cardiomyocytes in experimental epinephrine-induced damage to myocardium: enzyme activity and morphological parameters.

We studied the effect of xenogenic neonatal cardiomyocytes on enzymatic processes in rat myocardium under conditions of epinephrine-induced damage. It was found that transplantation of the cell preparation restricts the zone of suppressed enzyme activity in the myocardium and promotes its recovery. Less pronounced metabolic disturbances corresponded to less pronounced morphological changes in the myocardium.
