目的研究补阳还五汤(BYHWD)中生物碱、多糖、苷、苷元4类有效部位对大脑中动脉闭塞(MCAO)后局灶性脑缺血大鼠脑梗死的作用.方法用颈内动脉线栓法建立大鼠局灶性脑缺血模型,检测脑梗死体积,并比较其神经功能行为评分.结果脑缺血6 h,模型组脑梗死体积显著增大(P＜0.01),神经功能行为评分显著升高(P＜0.01);生物碱、多糖、苷、苷元各组脑梗死体积较模型组缩小(P＜0.05、0.01);生物碱、苷、苷元和多糖可使MCAO大鼠神经功能行为评分下降(P＜0.05、0.01),其中以生物碱和苷的作用较强.结论MCAO后,大鼠脑组织出现梗死,补阳还五汤4类有效部位生物碱、多糖、苷、苷元能减少脑梗死体积,改善脑缺血后神经行为...

Objective To investigate the effect of four kinds of active fractions (alkaloid, polysaccharide, glycoside, aglycone) of Buyang Huanwu Decoction (BYHWD) on the volume of cerebral infarction and the scores of nervous function behavior in focal cerebral ischemia rats after middle cerebral artery occlusion (MCAO). Methods The model rats of MCAO were induced by the method of nylon monofilament via the internal carotid artery for 6 h, image analysis technique was used to calculate the volume of cerebral infarction and to record the scores of nervous function behavior, then to compare them.
