观察尿激酶对急性脑梗死患者血液流变学的影响。方法：对４０例发病２４ｈ内的 急性脑梗死患者采用尿激酶溶栓治疗，检测患者溶栓治疗前后血液流变学的改变。结果：急性脑 梗死患者溶栓后，血液粘度（ｂ）、还原粘度（ｒ）、血浆粘度（ｐ）、微量纤维蛋白原（ＰＦＣ）、循环滞留时 间（ＭＳＴ）及血栓形态系数（ＴＦＬ）均显著性降低（Ｐ＜０．０５）；红细胞压积（ＨＣＴ）变化无显著性（Ｐ＝ ０．０５）。结论：尿激酶有降低血液粘滞性、改善微循环的作用。
To observe the effect of urokinase on hemorrheology in patients with acute cerebral infarction. Methods: Forty patients with acute cerebral infarction within 24 hours after onset of thrombolysis were treated with urokinase thrombolysis, and the changes of hemorheology before and after thrombolysis were detected. Results: After thrombolysis in patients with acute cerebral infarction, blood viscosity (b), reducing viscosity (r), plasma viscosity (p), trace fibrinogen (PFC), retention time (MST) and thrombus morphology index Significantly decreased (P <0.05); no significant change in hematocrit (HCT) (P = 0.05). Conclusion: Urokinase can reduce blood viscosity and improve microcirculation.
