[Changes in acetylcholinesterase and ATPase activity and certain structural features of the erythrocyte membrane in experimental myocardial ischemia].

Acute heart ischemia induced by ligation of the left coronary artery is associated with variation in the activity of acetylcholinesterase, Na, K-ATPase and Ca, Mg-ATPase in rat erythrocytes. The maximum pronounced variations in the enzymatic activity and in the membrane capacity of erythroblasts for binding direct turquoise are recorded on the 7th day of the experimental myocardial infarction.
