摘要: Abstract The potential for injury of myocardial sarcolemma by endogenous lipases was studied. sarcolemmal fraction incubated 30 min under conditions found optimal hydrolysis exogenous phosphatidylethanolamine (5 mM calcium, pH 7.0, 37°C). Incubation the increased significantly level total free fatty acids (14.1 to 31.1 nmoles/mg protein, P
