MethodsFocal cerebral ischemia was produced by permanent occlusion of the proximal of the right middle cerebral artery. The neurologic status of each rat was carefully evaluated at 24 h after surgery. The cerebral infarction numbers of neurons and nissls stains ,the water content were measured. Acute incomplete cerebral ischema was induced by ligaturing bilateral carotid arteries. Anoxia was produced by close normobaric hypoxia.

方法电凝大鼠一侧大脑中动脉造成局灶性脑缺血，观察脑血舒通对大鼠行为、大脑皮质内脑梗塞区神经细胞数量、尼氏小体含量、脑组织含水量的影响；采用结扎小鼠双侧颈总动脉形成急性脑缺血模型，并进行了小鼠常压耐缺氧实验，观察小鼠存活时间。
