Abstract

Protective effect of urokinase on reperfusion were studied followed by global ischemia in the isolated perfused rat heart. Separately, anti-platelet aggregation effect of urokinase also investigated. Urokinase exhibited positive effect for the protection of rat heart function by increasing the LV dp/dt, coronary flow(CF) and the Tate pressure product(RPP), and by decreasing the LVEDP on reperfusion. Urokinase also decreased arrhythmia by $74.7\%(P<0.05) induced by global ischemia in the rat heart. In the platelet aggregation study, urokinase did not show the inhibitory effect of ADP or collagen induced platelet aggregation inviuo and exvivo.
