[Mechanism of changes in lymphocyte dehydrogenase activity during heart transplantation].

A study was made of the activity of succinic dehydrogenase (SDH) and of the alpha-glycerophosphoric dehydrogenase (alpha-GPDH) in the peripheral blood lymphocytes and the transplant myocardium in the CBA mice in transplantation to them of the heart of newborn C57BL/6 mice into the pinna, subcutaneously. It appeared that the (see article) ratio in the myocardium and the lymphocytes of intact animals and also in the recipients of the isolinear transplant of the heart was greater than 1, but in allogenous transplantation this ratio became less than 1 on account of alpha-GPDH activation in the blood lymphocytes, which preceded the inversion in the transplant myocardium. It is supposed that the mentioned phenomenon was associated with the development of the immunological conflict.
