已经研究了颈动脉内输注尿激酶在狒狒急性血栓性中风模型中挽救神经功能的能力。该模型包括对位于豆纹动脉 (LSA) 起点附近的右侧大脑中动脉 (MCA) 进行可逆偏心球囊压缩(3 小时),导致供应右侧纹状体的穿支发生原位血栓形成。神经学终点包括神经功能(NE)的定量评估、通过计算机断层扫描(CT)扫描估计脑梗死体积以及颈动脉造影。在未经治疗的急性中风对照动物 (n = 6) 中,第 14 天时功能评分持续下降(从 100 降至 36 +/- 11),第 10 天时检测到确定的脑梗塞区域(体积 = 3.2 +/- 1.5)。在 MCA 闭塞 3 小时后,对 5 只动物施用颈动脉内尿激酶(60 分钟内 1.2 X 10(6) IU),改善了神经功能(NE = 50、55、85、100、100)并减少了梗塞面积(分别为 0.3、0.5、0.8、0.7、1.1 cm3),且无颅内损伤证据出血。所有五只接受治疗的动物均产生了全身纤维蛋白原溶解。我们的结论是,实验性血栓闭塞后 3 小时内进行溶栓治疗可以挽救神经功能并减少脑梗塞体积,且 CT 扫描不会检测到颅内出血。
The capacity of intracarotid infusion of urokinase to salvage neurologic function in a baboon model of acute thrombotic stroke has been studied. The model consists of reversible eccentric balloon compression (3 hours) of the right middle cerebral artery (MCA) proximal to the take-off of the lenticulostriate arteries (LSA), resulting in in situ thrombosis of perforating branches supplying the right corpus striatum. Neurologic endpoints included quantitative assessment of neurologic function (NE), estimation of cerebral infarction volume by computerized tomographic (CT) scan, and carotid angiography. In untreated acute stroke control animals (n = 6), a persistent decrease in functional score (from 100 to 36 +/- 11) at 14 days and a defined region of cerebral infarction (volume = 3.2 +/- 1.5) were detected at 10 days. Intracarotid urokinase administered to five animals (1.2 X 10(6) IU over 60 min) following the 3 hour period of MCA occlusion improved neurologic function (NE = 50, 55, 85, 100, 100) and reduced infarction size (0.3, 0.5, 0.8, 0.7, 1.1 cm3, respectively) without evidence of intracranial hemorrhage. Systemic fibrinogenolysis was produced in all five treated animals. We conclude that thrombolytic therapy given within 3 hours of experimental thrombotic occlusion may salvage neurologic function and reduce cerebral infarction volume without CT scan detectable intracranial bleeding.
