摘要: 摘要: 目的 观察七十味珍珠丸 (RNSP) 对大鼠脑缺血再灌注损伤的保护作用及抗凋亡机制。方法 采用大脑中动脉阻塞模型, 实验分组: 假手术组、 模型组、 溶媒对照组和 RNSP 组。神经功能缺失评分观察大鼠神经缺失体征,红四氮唑染色测量脑组织梗死面积, 及 Western blot 检测海马组织 Bcl-2/Bax 比值和 caspase-3 的蛋白表达。结果与假手术组比较, 模型组大鼠神经缺失体征明显, 脑梗死面积明显增加, Bcl-2/Bax 比值减小, caspase-3 蛋白表达明显升高。而与模型组比较, RNSP 组大鼠神经缺失体征明显改善, 脑梗死面积减少, Bcl-2/Bax 比值增大, caspase-3 蛋白表达明显降低。结论 RNSP 对大鼠脑缺血再灌注损伤具有保护作用, 与其上调 Bcl-2/Bax 比值, 减少 caspase-3 蛋白表达的抗凋亡作用有关。

Abstract: Abstract:Objective To observe the protective and anti-apoptosis effects of Rannasangpei (RNSP) on brain ischemia and reperfusion injury in rats. Methods Middle cerebral artery occlusion (MCAO) model was established and the groups were divided as sham group, MCAO group, vehicle + MCAO group and RNSP + MCAO group. Neuronal deficient signs, brain infarct area, the ratio of Bcl-2/Bax and the expression of caspase-3 were evaluated by neuronal deficient score, TTC (2, 3, 5-Triphenyltetrazolium chloride) staining and Western blot respectively. Results Compared with those parameters in sham group, the neuronal deficient signs, infarct area and caspase-3 expression increased evidently while the ratio of Bcl-2/ Bax decreased markedly in MCAO group. But in RNSP + MCAO group, the neuronal deficient signs, infarct area and cas⁃ pase-3 expression decreased greatly while the ratio of Bcl- 2/Bax increased markedly compared with those parameters in MCAO group. Conclusion RNSP may have protective effects on brain ischemia and reperfusion, which is related to its an⁃ ti-apoptosis role indicated by upregulation of Bcl-2/Bax ratios and downregulation of caspase-3.
