摘要
通过兔颈内动脉梗塞模型评价不同时间给予UK溶栓治疗的疗效和安全性。发现栓塞后0.5、2、4、6h溶栓治疗组与相应的对照组的梗塞灶占半球的百分率分别为2.60±1.40%/38.36±4.01%(P<0.001)、11.96±3.12%/38.10±3.43%(P<0.001)、27.13±5.95%/39.06±4.02%(P<O.01)、38.220±498%/37.77±3.18%(P>0.05)。栓塞后0.5、2h溶栓治疗组未见脑出血.4、6h组部分动物见脑出血。提示兔脑栓塞后早期给予UK治疗可缩小脑梗塞体积,减少脑损害;过迟溶栓治疗不能缩小梗塞灶,且有增加脑出血的危险。
To evaluate the efficacy and safety of delayed therapy with urokinase in a rabbit model ofthromboembolic stroke. The mean infarct size of groups treated with urokinase O. 5、2、4, 6hours after em-bolization and control groups were 2. 60±1. 40% /38.36±4.01% (P <0.001)、 11.96±3.12 % /38.10±3. 43% (P <0.001)、27.13±5. 95%/39.06±4.02% (P<0.01)、38. 220±4. 98%/37. 77±3.18% (P>0.05 ). No cerebral hemorrhage was found in the groups treated with urokinase at 0.5, 2h after em-bolization, there were brain hemorrhage animals in the 4、6houres delayed therapy groups. It indicatedthat early administration of urokinase could reduce the infarct size and improve the clinical outcome. the in-farct size couldn't be reduced when urokinase therapy delayed longer and probaboy increased the risk ofhemorrhagic transformation.
