摘要: 目的: 研究七叶心康胶囊对大鼠脑缺血/再灌注损伤的影响。 方法: 采用栓线法制备大鼠脑缺血/再灌注损伤模型,通过神经功能学评分、红四氮唑(TTC)染色法、称重法检测研究七叶心康胶囊对大鼠脑缺血/再灌注损伤的保护作用;制作大脑海马匀浆测定超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)的活性和一氧化氮(NO)、丙二醛(MDA)的含量来探讨其保护大鼠脑缺血/再灌注损伤的作用机制。 结果: 七叶心康胶囊灌胃给药,连续4次,分别为再灌注后1、12、24、36 h 各给药一次,在270、135 mg/kg 的剂量下能显著改善大鼠受损的神经功能障碍和脑梗死范围;降低大脑含水量;还能够明显增加脑组织中SOD、GSH-Px的活性和降低MDA、NO的含量。 结论: 七叶心康胶囊对大鼠脑缺血/再灌注损伤有明显的保护作用,此作用可能与其抑制脑组织脂质过氧化反应和减少NO的生成有关。

Abstract: AIM: To study the influence of qiye xinkang capsule (QXC) on the cerebral ischemia-reperfusion injury in rats. METHODS: Aften the model of cerebral ischemia-reperfusion injury in rats was simulated successfully by string occlusion, protective effect of QXC on cerebral ischemia-reperfusion injury was evaluated by neurofunctional score, red tetrazoline (TTC) and weighing method.The mechanism was investigated by determining the activity of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), nitric oxide (NO) and malondialdehyde (MDA) from rat hippocampus homogenate. RESULTS: The rats replicated successfully were orally administered with QXC for four times: 1 h for the first time, 12 h for the second time, 24 h for the third time and 36 h for the forth time.The neurological deficit and brain infarction area resulted from cerebral ischemia in rats were improved significantly,meanwhile the water content and content of MDA and NO were decreased significantly and the activity of SOD and GSH-Px was increased significantly in the tissue of cerebral ischemia in dose of 271.3 and 135.6 mg/kg. CONCLUSION: QXC had notable protective effect on cerebral inchemia-reperfusion injury in rats, which might be related with inhabiting the lipid peroxidation of the brain tissue and reducing the generate of the NO.
