| 摘 要： | 为了探讨中药复方髓伤平 (SSP)对全脑缺血再灌流大鼠模型脑保护作用的机制 ,阻断 1 8只SD大鼠双侧颈总动脉血流 3 0min后 ,解除阻断再灌流 2h ,造成脑缺血再灌流损伤模型。造模大鼠随机分为 3组 :缺血再灌流组(BG) ,SSP治疗组 (SG) ,尼莫地平对照组 (NG) ;另设不造模的正常对照组 (NCG) 6只。分别检测 4组大鼠脑组织内丙二醛 (MDA)质量摩尔浓度及超氧化物歧化酶 (SOD)活性。发现 :BG组大鼠脑内MDA质量摩尔浓度明显升高 (P <0 .0 5 ) ,SOD活性则明显下调 (P <0 .0 5 )。SSP能使升高的MDA适度降低 ,并且上调SOD活性。提示 :在大鼠脑缺血再灌流条件下 ,SSP可以清除脑内过多的氧自由基 ,对脑起保护作用。

| Abstract: | The objective was to observe the protective effect of Chinese herbal compound, Suishangping (SSP) on ischemia reperfusion injury of the brain. Altogether 24 Sprague-Daleg rats were randomly divided into four groups: normal control group (NCG), ischemic injury group (BG), SSP group (SG) and nimodipine group (NG). It was followed by reperfusion of blood for 2 h to blockade blood flow in the common carotid artery with silk ligature for 30 mins in BG, SG, and NG. SOD activity and MDA content were detected in various groups. It has been demonstrated that MDA value in rats-SG was lower than that in rats-BG (P<0.05), and SOD activity in rats-SG was higher than that of BG ( P< 0.05). It shows that SSP can reduce the contents of MDA, and stimulate SOD activity, so that it maybe indirectly resist the damage of oxygen-derived free radicals. |
