摘要: 目的 研究滇橄榄提取物对大鼠局灶性脑缺血再灌注损伤的保护作用及机制。方法 大鼠大脑中动脉线栓法制作脑缺血再灌注模型。进行神经功能学评分、梗死面积测定、脑组织超氧化物歧化酶(SOD)、丙二醛(MDA)、一氧化氮(NO)、白细胞介素-1β(IL-1β)、白细胞介素-6(IL-6)、诱导性一氧化氮合酶(iNOS)、核转录因子NF-κB的水平。结果 滇橄榄提取物能减少局灶性脑缺血再灌注大鼠的神经功能评分和脑梗死面积,提高脑组织SOD活性,降低MDA、NO、IL-1β、IL-6、iNOS和NF-κB的水平。结论 滇橄榄提取物对大鼠脑缺血再灌注损伤具有明显的保护作用,其机制可能与抗氧化和抑制炎症有关。

Abstract: AIM: To study the protection and mechanisms of extract of Phyllanthus emblica L.(EPE) on focal cerebral ischemia-reperfusion injury in rats. METHODS: The cerebral ischemia-reperfusion rats' models were created by the middle cerebral artery occlusion by modified suture method. The neurological function scores were observed, the infarct size was measured by TTC staining, and the contents of SOD, MDA, NO, IL-1β, IL-6, iNOS and NF-κB in brain tissue were measured. RESULTS: Compared with the model group, EPE could significantly reduce the neurological function scores, decrease the cerebral infarct size, increase the activity of SOD, and reduce the contents of MDA, NO, IL-1β, IL-6, iNOS and NF-κB in brain tissue. CONCLUSION: EPE has significant protection on cerebral ischemia-reperfusion injury in rats due to increases the antioxidant activity and inhibit inflammatory reaction.
