A study was made of the effect of plasmin and trypsin on the phospholipase activation, and also of the action of phospholipase A (cobra venom) on the release reaction and the erythrocyte and thrombocyte aggregation. Trypsin and fibrinolysin proved to activate phospholipase, this being accompanied by the accumulation of nonesterified fatty acids in the blood serum. Phospholipase A caused a release of the thromboplastic factor from erythrocytes and thrombocytes and their aggregation. The later is inhibited by albumin and EDTA. It is suggested that the action of the proteolytic enzymes on the blood formed elements was realized through the phospholipase activation.
