因血管内出现血凝块而形成血栓,随之产生“急性心肌梗塞”“肺栓塞”等一系列血管栓塞病。这些疾病有很高的死亡率,严重的威胁着人类的健康。以链激酶和尿激酶为代表的,酶解血栓疗法给这些疾病带来了很大的希望,它们通过图示方式溶解血栓。如图所示,链激酶或尿激酶激活存在血栓中的胞浆素原,使转化成胞浆素。胞浆素又分解不溶性的纤维蛋白成为可溶性的纤维蛋白裂解产物。于是血栓便溶解。 Blood clots due to blood clots and the formation of thrombus, followed by a “acute myocardial infarction” “pulmonary embolism” and a series of vascular embolism. These diseases have a high mortality rate, which is a serious threat to human health. Enzymatic thrombolytic therapy, typified by streptokinase and urokinase, offers great promise for these diseases by dissolving thrombi in graphical fashion. As shown, streptokinase or urokinase activates the presence of plasminogen in the thrombus, allowing the conversion to cytoplasm. Plasma proteins, in turn, break down insoluble fibrin to become a soluble fibrin cleavage product. Thrombosis will dissolve.
