川芎赤芍提取物不同配比的活血化瘀作用研究

目的观察不同比例的川芎和赤芍有效部位提取物的配伍对大鼠活血化瘀的作用,探讨其活血化瘀的最佳比例关系.方法用肾上腺素建立血瘀动物模型,观察川芎和赤芍的有效部位提取物不同比例组成的药对大鼠血小板聚集、血小板黏附、红细胞聚集等血液流变学指标的影响.结果造模后大鼠血管明显收缩,血小板聚集性显著增高,红细胞聚集性明显增强且变形性发生改变,大鼠血液黏度升高,川芎和赤芍的有效部位提取物不同比例组成的药对皆有一定程度降低大鼠血液黏度、改善红细胞变形能力、降低红细胞聚集指数和抑制血小板聚集性的作用,其中川芎和赤芍提取物0.45 g:0.45 g组和0.21 g:0.45 g组作用较强.结论川芎和赤芍提取物组成的药对可显著改善大鼠的血液流变性,川芎和赤芍提取物0.45 g:0.45 g组和0.21 g:0.45 g组作用较佳.

Effect of the Extracts from Rhizoma Chuanxiong and Radix Paeoniae Rubra in Different Proportions on Promoting Blood Circulation and Removing Blood Stasis

Objective To observe the effect of drug pairs of extracts from Rhizoma Chuanxiong(RC)and Radix Paeoniae Rubra(RPR)in different proportions on promoting blood circulation and removing blood stasis in rats and to find the optimal proportion between the two extracts.Methods The Wistar rat models of blood stasis were established by injection of adrenalin.The changes of the platelet aggregation and adhesiveness and erythrocyte aggregation were observed.Results Blood vessel contraction increased,the platelet aggregation and erythrocyte aggregation increased,erythrocyte deformation occurred and the blood viscosity increased in the model rats.The drug pairs could reduce blood viscosity,ameliorate erythrocyte ability of deformation,reduce erythrocyte aggregation and inhibit platelet aggregation.The effects were obvious especially in the groups of RC and RPR in the proportions of 0.45 g to 0.45 g,0.21 g to 0.45 g.Conclusion The drug couples from RC and RPR in different proportions could improve the blood rheology,the effect being obvious in the groups of RC and RPR in the proportions of 0.45 g to 0.45 g,0.21 g to 0.45 g.
