纤维蛋白溶解酶系统的功能是控制纤维蛋白在血管和血管外系统的沉积。纤溶系统的关键物质是纤溶酶原,当其被激活时,释放出纤溶酶。近来对纤溶系统的天然激活因子和血浆抑制因子分子间相互作用的认识有了很大进展。同时,对纤溶系统外源性激活剂(链激酶、尿激酶、组织型纤溶酶原激活剂)及其拮抗物,如 The function of the fibrinolytic enzyme system is to control the deposition of fibrin in the vascular and extravascular systems. The key substance of the fibrinolytic system is plasminogen, which, when activated, releases plasmin. Recent advances in the understanding of the interaction between the natural activator of plasma fibrinolysis and the plasma inhibitor molecule have progressed. At the same time, the fibrinolytic system exogenous activators (streptokinase, urokinase, tissue-type plasminogen activator) and its antagonists, such as
