摘要: 目的: 观察异丙酚和异氟醚对大鼠全脑缺血 再灌注损伤的影响。方法: 雄性 SD 大鼠随机分为 2 组, 每组14 只, 分别在异丙酚和异氟醚麻醉下行全 脑缺血 15 min, 每组各 7 只于再灌注后 30 min 和 3 d 测SOD活性和 MDA 含量或海马 CA1 区存活神 经元计数。结果: 异丙酚组大鼠海马和皮层 SOD 活 性显著高于异氟醚组(P<0.01), MDA 含量显著低 于异氟醚组(P<0.01)。 异丙酚组海马 CA1 区成活 神经元计数显著多于异氟醚组(P<0.05)。 结论: 异丙酚对大鼠脑缺血再灌注损伤的保护作用强于异 氟醚, 其机制与其减轻氧自由基损伤有关。

Abstract: AIM: To explore the effects of propofol and isoflurane on total cerebral ischemia-reperfusion inju-ry of rats.METHODS: Male SD rats were randomly di-vided into two grougs (n =14), which were respectively anesthetized with propofol and isoflurane under mechani-cal ventilation.Global cerebral ischemia was induced by occlusions of bilateral common carotid and vertebral arter-ies (four vessels).Each group was divided into two sub-groups according to reperfusion time:30 min for detecting MDA and SOD in brain tissues and 3 d for detecting sur-vived CA1 Cells of hippocampus.RESULTS: The cont-ents of MDA was more after 30 min reperfusion in isoflu-rane group than that in propofol group (P<0.01), whereas the activities of SOD was higher in propofol group than that in isoflurane group(P<0.01).There were more survived neurons in CA1 after 3 day reperfusion in propofol group than in isoflurane group(P<0.05). CONCLUSION: Propofol has stronger protection effect in general brain ischemia-reperfusion injury, the mecha-nism is associated with the activity of oxide free radical.
