在纤溶酶原缺乏(Plg(-/-))、组织或尿激酶纤溶酶原激活物(tPA(-/-)或uPA(-/-))、或纤溶酶原激活物抑制剂-1或α(2)-抗纤溶酶(派-1(-/-)或α(2)-AP(-/-))。方法和结果-通过结扎左侧大脑中动脉产生FCI,并在24小时后通过染色脑切片的面积测量法测量。在对照组(野生型)小鼠中,梗死面积为7.6+/-1.1 mm(3)(平均值+/-SEM),uPA(-/-)小鼠的梗死面积相似(7.8+/-1.0 mm(3),P=NS),tPA(-/-)小鼠的梗死面积较小(2.6+/-0.80 mm(3),P
Background-The role of plasminogen system components in focal cerebral ischemic infarction (FCI) was studied in mice deficient in plasminogen (Plg(-/-)), in tissue or urokinase plasminogen activator (tPA(-/-) or uPA(-/-)), or in plasminogen activator inhibitor-1 or alpha(2)-antiplasmin (PAI-1(-/-) or alpha(2)-AP(-/-)).Methods and Results-FCI was produced by ligation of the left middle cerebral artery and measured after 24 hours by planimetry of stained brain slices. In control (wild-type) mice, infarct size was 7.6+/-1.1 mm(3) (mean+/-SEM), uPA(-/-) mice had similar infarcts (7.8+/-1.0 mm(3), P=NS), tPA(-/-) mice smaller (2.6+/-0.80 mm(3), P
