Aprotinin Inhibits Plasmin-Induced Platelet Activation During Cardiopulmonary Bypass

Abstract: Aprotinin has indirect effects to inhibit platelet activation, and this may partly explain the reduction of blood loss during cardiac surgery. To prevent the adverse effects, a single and minimal use of aprotinin is important. The results of in vivo and in vitro studies suggest that platelet preservation was demonstrated by the lower concentration of aprotinin (1.0 x 10(6) KIU per patient or 10 KIU/mL) compared with the concentration that inhibits plasma fibrinolysis.

“…Thus, plasmin induces neutrophil aggregation, platelet degranulation, and arachidonate release from endothelial cells, implying activity as a proinflammatory agonist. [6][7][8] Moreover, plasmin was found to be a potent and selective stimulus for human peripheral monocytes. [2][3][4] In monocytes, plasmin triggered the release of lipid mediators, such as the chemotactic leukotriene B 4 , and a chemotactic response equipotent to that of N-formyl-methionine-leucine-phenylalanine.…”

“…However, the serine protease plasmin might have functions beyond fibrinolysis. Thus, plasmin induces neutrophil aggregation and platelet degranulation, implying activity as a proinflammatory agonist (4,5). Moreover, plasmin was found to be a potent and selective stimulus for human monocytes eliciting release of lipid mediators, such as chemotactic leukotriene B 4 , as well as a chemotactic response equipotent to that of fMLP, 1 and proinflammatory cytokine and tissue factor expression (6 -9).…”

“…Показано [16], що плазмін у кількості 0,8 CU/мл індукував секрецію та агрегацію відмитих тромбоцитів, які пригнічувалися за наявності 50 IU/мл апротиніну, що вказує на провідну роль у цих процесах протеїназної активності плазміну. Виявилося, що він здатний активувати тром-боцити через розщеплення рецептора PAR-4 [17].…”

“…Результати дослідження Shigeta та співавт. [16] демонструють, що плазміноген здатний інгібувати плізмініндуковану актива-цію та секрецію тромбоцитів, однак повного їх інгібування не спостерігається навіть за наявності зимогену у кількості, що у чоти-Рис. 1.…”
