目的探讨三七总皂苷(TSPN)对全脑缺血后成年大鼠海马胶质纤维酸性蛋白(GFAP)表达及脑水肿的影响。方法采用四血管阻断法制作全脑缺血模型,大鼠被随机分成假手术组、模型组和TSPN组。TSPN组大鼠全脑缺血后30 min ip 75 mg/kg TSPN,每天1次,假手术组和模型组ip给予等体积的生理盐水,连续14 d。分别于再灌注1、3、7、14 d后处死。采用干湿法计算各组大鼠脑组织含水量,免疫组织化学染色观察海马齿状回(SGZ)区GFAP的表达,免疫荧光双标观察SGZ区GFAP/DCX的共表达情况,免疫印迹技术检测海马CA1区GFAP蛋白表达水平。结果TSPN组大鼠脑组织含水量显著低于模型组(P

Objective To explore the effect of the total saponins of Panax notoginseng (TSPN) on the expression of GFAP in hippocampus and brain water content in rats subjected global cerebral ischemia injury. Methods Using four-vessel occlusion method built the global cerebral ischemia model. Rats were divided into Sham group, vehicle group, and TSPN group. The rats in the TSPN group were administered TSPN intraperitoneally 30 min post-brain ischemia. The dose of TSPN (75 mg/kg) was suspended in 0.9% saline, once per day for days 1, 3, 7, and 14 after rep...
