为了研究脑缺血损伤后的生化改变及其临床意义，采用线结扎兔颈动脉法建立兔脑缺血模型，Ａ组（ｎ＝５）结扎双侧颈动脉；Ｂ组（ｎ＝５）结扎单侧颈动脉，３０ｍｉｎ时松开结扎线使颈动脉再灌流；Ｃ组（ｎ＝５）为假结扎组。结果：３组动物中，Ａ组兔全部死亡，Ｂ组和Ｃ组兔全部成活；后２组相比，Ｂ组兔脑脊液分泌量减少，麻醉苏醒延迟，术后２４ｈ时有神经缺失体征。提示：结扎兔单侧颈动脉可制成不完全脑缺血模型
In order to study the biochemical changes after cerebral ischemia injury and its clinical significance, a rabbit model of cerebral ischemia was established by ligating rabbit carotid arteries. A (n = 5) ligated bilateral carotid arteries in group B (n = 5) Unilateral carotid artery, the ligature was released at 30 min to reperfusion the carotid artery; group C (n = 5) was ligated. Results: In group A, all rabbits in group A died and rabbits in groups B and C all survived. Compared with the latter two groups, cerebrospinal fluid secretion of rabbits in group B was decreased, anesthesia was delayed and awake at 24 hours after operation. Tip: unilateral ligation of rabbit carotid artery can be made incomplete cerebral ischemia model
