摘要: 目的建立非人灵长类脑梗死慢性期动物模型。方法雄性成年恒河猴10 只,血管内介入栓塞动物利手对侧大脑中动脉。依栓塞节段不同,分为M1 段栓塞组(n=3)、上干栓塞组(n=5)和下干栓塞组(n=2)。通过标准神经量表和小槽食丸取回任务评定运动功能。结果M1 段栓塞组均在急性期死亡。上干栓塞组均存活,MRI 可见梗死灶,急性期一侧肢体瘫痪,其中4 只功能障碍在慢性期持续存在,另外1 只运动功能恢复。下干栓塞组急性期一侧肢体瘫痪,运动缺陷恢复迅速且完全。结论大脑中动脉上干栓塞动物模型存活率高,慢性期存在运动功能障碍,适合于慢性期研究。

Abstract: Objective To establish chronic cerebral infarction animal model in nonhuman primate. Methods 10 adult male rhesus monkeyswere embolized the middle cerebral artery (MCA) in contra-lateral of handedness, and divided into M1 segment embolism group (n=3), upper trunk embolism group (n=5), and lower trunk embolism group (n=2). Acute neurological deficit was evaluated with standard neurologicalscale, and the motor function in chronic stage was assessed with a task of retrieving food pill in wells. Results Animals in M1 segmentembolism group all died 38~62 h after surgery. Upper trunk embolism group survived, and MRI showed front parietal cortex infarctioncontra-lateral paralyzed side. All of them paralyzed one side in acute stage, and 4 of them persisted dysfunction in chronic stage, that couldnot finish the task of retrieving food pill in wells; only one completed the task. The lower trunk embolism group paralyzed one side in acutestage, but recovered quickly and completely, that finished the task within 7 d. Conclusion Embolism of MCA upper trunk can cause infarctionof precise and proper size with one side limb dysfunction in the acute stage and long-term dysfunction in most animals, which is feasiblefor treatment and neural plasticity research in recovery.
