目的 研究补阳还五汤中4类有效部位抗脑缺血再灌注损伤作用是否是通过抑制脑组织caspase表达而实现的.方法 采用大鼠大脑中动脉闭塞局灶性脑缺血模型,缺血2 h再灌注46 h,分别于缺血前和缺血后12、24、36 h给予由补阳还五汤提取的生物碱、苷、多糖和苷元,以尼莫地平为对照药.以免疫组化法检测caspase-1、caspase-3、caspase-8蛋白表达.结果 脑缺血再灌注后,缺血侧脑组织caspase-1、caspase-3蛋白表达增强,caspase-1主要表达在脉络膜,caspase-3在海马、皮质和髓质均有表达.补阳还五汤中生物碱、苷、多糖和苷元均可抑制caspase-1表达,尼莫地平对caspase-1表达无显著影响.生物碱可抑制海马和髓质区c...

OBJECTIVE: To investigate effect of the four kinds of active fractions extracted from Buyang Huanwu Decoction (BYHWD) on caspase expression in rats after focal cerebral ischemic reperfusion. METHODS: The focal cerebral ischemia/reperfusion model rats were established by middle cerebral artery occlusion for 2 hrs followed with reperfusion for 46 hrs. Before and at 12th, 24th and 36th hour after cerebral ischemia, the rats were administered with alkaloid, glycoside, polysaccharide and aglycone from BYHWD respectively, and nimodipine was given as control medicine to observe the effect of them on ...
