title: Chemical control of hyperfibrinolytic states by synthetic inhibitors of fibrinolytic enzymes.
abstract: The effects of two types of synthetic inhibitor of fibrinolytic enzymes (omega-aminocarboxylic acids, benzamidine derivatives) on intravascular fibrinolysis and fibrinogenolysis were studied in rats. Generalised primary fibrinogenolysis was produced by infusion of human plasminogen-streptokinase complex, secondary fibrinolysis was induced by infusion of the thrombin-like enzyme batroxobin. The inhibitors exerted different effects on the hyperfibrinolytic states. The omega-aminocarboxylic acids (PAMBA, AMCA) inhibited fibrinolysis more effective than fibrinogenolysis. In contrast, the benzamidines (APPA, NANP) were more potent inhibitors of fibrinogenolysis. Aprotinin examined for comparison behaved like the benzamidine derivatives.
