Evaluation of myocardial energy parameters during simulation of epinephrine damage under conditions of cell transplantation.

The effects of transplantation of xenogenic neonatal heart cells on energy processes were studied in rat myocardium during the early period of epinephrine injury. Transplantation promoted a less pronounced ATP hydrolys to adenosine monophosphate and inorganic phosphate, a higher level of creatine phosphate, pyruvate, lactate, retention and activation of myocardial enzymes involved in energy metabolism.

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.
