[Effect of a "direct" hemolytic factor and phospholipse A2 from Middle-Asian cobra venom on erythrocytes].
The effect of "direct" hemolytic factor (DHF) and phospholipase A2, isolated and purifed from Middle-Asian cobra venom on human erythrocytes is studied. DHF is found to increase the hemolytic effect of phospholipase A2 Ca2+ ions inhibit the hemolytic effect of DHF, but they increase the hemolysis in the presence of DHF and phospholipse A2. Heparin re moves the increasing effect of DHF. Possible mechanisms of the hemolytic effect of DHF and phospholipase A2 are discussed.
