Urokinase is isolated from the urine of healthy people, or an enzyme obtained from the tissue culture of human renal protein. By the molecular weight for 33000 (LMW-tcu-PA) and 54000 (HMW-tcu-PA) consists of two parts. This product directly on endogenous fibrinolytic system can catalyze the cleavage of plasminogen into plasmin, which can degrade the fibrin clots also can degrade the circulating Fibrinogen, coagulation factor v and factor VIII, and Thrombolysis role to play. The product of the newly formed blood clots work faster and better. This product also improves the effect of ADP enzyme activity, inhibition of ADP-induced platelet aggregation, preventing thrombosis. This product after the intravenous drip, fibrinolytic activity in the patients with markedly improved; stopped a few hours later, fibrinolytic enzymes levels.
