Methods:Rat model of cerebral ischemia was established by applying middle cerebral artery occlusion(MCAO).
方法:①用复制大脑中动脉闭塞(MCAO)模型研究FBD对脑缺血再灌注大鼠行为学评分、梗死面积、脑含水量、脑组织中生化指标(丙二醛、Na+-K+-ATP酶、Ca2+-ATP酶、一氧化氮)及脑组织学的影响;②用小鼠脑缺血再灌注模型研究FBD对血脑屏障通透性的影响。
补充资料：闭塞性动脉硬化
闭塞性动脉硬化
系指由于动脉粥样硬化累及中、小动脉，而使其逐渐变窄或闭塞的一种疾病。多发生于老年人，糖尿病患者易发生。其原因尚未查明，近年认为可能与脂质代谢紊乱，血流动力学改变，动脉壁的功能障碍以及凝血和纤溶系统的紊乱等因素有关。常见下肢动脉干的闭塞性硬化，患肢因缺血而出现发凉、麻木、疼痛、间歇性跛行等症状，久之因患肢长期缺血，营养障碍，可发生局部溃疡和坏疽或继发感染。治疗可用中医药及降血脂、降压等疗法，必要时手术治疗，但主要还在于预防动脉硬化。
