摘要: 目的:证实双萜类化合物ST-1 的抗大鼠脑局灶性缺血再灌注损伤作用。方法:大鼠大脑中动脉内栓线阻断法制作脑缺血再灌注模型, 以行为学、脑梗死体积、脑匀浆丙二醛(MDA) 含量和超氧化物歧化酶(SOD) 的活力和海马CA1 区神经元的病理学等指标评价ST-1 的抗脑局部缺血复灌损伤作用。结果:大鼠静脉注射ST-1 5 ~ 20 mg·kg-1, 剂量依赖性地降低脑局灶性缺血再灌注引起的梗死体积, 降低脑MDA 的含量, 增加SOD 活力, 减轻海马CA1 区神经元损伤;高剂量组行为学损伤明显减轻。结论:ST-1 有抗大鼠脑局灶性缺血再灌注损伤作用。

Abstract: AIM: To demonstrate the protective effects of ST-1 against focal cerebral ischemia-reperfusion injury in rats.METHODS: The model of focal ischemiareperfusion was induced by middle cerebral artery occlusion 2 h followed by reperfusion 22 h in rats.Neurological deficit scores were evaluated.Infarct size, malondialdehyde (MDA) content and superoxide dismutase (SOD) activity were measured, pathological changes of neurons in hippocampal CA1 region were observed.RESULTS: Compared with vehicle group ST-1 at dose of 10 and 20 mg·kg -1 could reduce the infarct size, MDA content, enhance SOD activity and relieve neurons injury in hippocampal CA1 region in dose-dependent way;ST-1 at dose of 20 mg·kg -1 could also improve neurological function. CONCLUSION: ST-1 can protect brain tissue from focal ischemia-reperfusion injury.
