采用开颅电凝阻断大鼠一侧大脑中动脉并结扎同侧颈总动脉的方法，复制了局灶性脑缺血模型。应用神经检查分级评估法、组织化学染色和计算机图象处理系统，证实了该模型的可靠性。 Focal cerebral ischemia model was reproduced by the method of craniotomy coagulation to block the rat middle cerebral artery and ligate the ipsilateral common carotid artery. The reliability of the model was confirmed by applying the neurological grading and grading method, histochemical staining and computer image processing system.
