[Study of autolytic changes in human myocardial proteins by two-dimensional electrophoresis].

Alterations of myocardial proteins were studied in the left ventricular tissue of adult persons and fetuses during natural autolysis. The most pronounced alterations were observed in proteins from regions of myosin light chains, region 119 and the region of muscle enzymes. When autolysis was studied in the myocardium and skeletal muscle, proteolytic alterations were observed in skeletal muscles later.
