摘要:

目的: 探讨滁菊总黄酮对大鼠脑缺血再灌注损伤的保护作用。方法: 将48只SD大鼠随机分为6组,假手术组、模型组、滁菊总黄酮组(40、80和160 mg/kg)、尼莫地平组,每组8只,腹腔注射给药。采用线栓法阻塞大鼠右侧大脑中动脉,制备大鼠脑缺血再灌注损伤模型,缺血2 h,再灌注24 h,进行神经行为评分、脑组织含水量测定、脑梗死体积测定、脑组织丙二醛(MDA)含量测定。结果: 40、80和160 mg/kg滁菊总黄酮可降低大鼠脑组织含水量、减小脑梗死体积、降低脑组织MDA含量(P<0.05或P<0.01);160 mg/kg的滁菊总黄酮可以降低大鼠的神经行为评分(P<0.01)。结论:滁菊总黄酮对大鼠脑缺血再灌注损伤具有保护作用,可能与其抗氧化活性有关。

Abstract:

AIM: To study the protective effects of total flavonoids of Chuzhou chrysanthemum (TFCC) against cerebral ischemia reperfusion injury in rats.  METHODS: 48 SD rats were randomly assigned into 6 groups of sham operation group, model control group, nimodipine group, TFCC 40, 80 and 160 mg/kg groups, with 8 rats in each group, which employed intraperitoneal administration. The ischemic model was established with line embolism to block the middle cerebral artery of rats, with 24-hours-reperfusion after 2-hours-ischemia. 24 hours after modeling, the protective effect of TFCC was determined by behavioral neurological damage scores, water content of brain tissue, cerebral infarction volume. The content of malondi-aldehyde (MDA) in brain tissue were measured.RESULTS:40, 80 and 160 mg/kg TFCC can reduce water content of brain tissue and cerebral infarction volume, and decrease the content of MDA in brain tissue (P<0.05 or P<0.01); 160 mg/kg TFCC reduced neurobehavioral score of rats (P<0.01). CONCLUSION: TFCC has a protective effect on cerebral ischemia reperfusion injury in rats, the effect may be associated with its antioxidant activity.

Key words: total flavonoids of Chuzhou chrysanthemum, cerebral ischemia reperfusion injury, infarction volume, malondi-aldehyde
