蒲黄与蒲黄炭对血瘀大鼠血液流变性及凝血时间的影响

目的:比较蒲黄及蒲黄炭对血瘀模型大鼠血液流变性及凝血时间的影响。方法:SD大鼠随机分为6组,分别为正常组,模型组,云南白药组0.27 g·kg-1,蒲黄生品水提组1.2 g·kg-1,蒲黄炭水提组1.2 g·kg-1,蒲黄炭粉组1.2 g·kg-1。除正常组外,其余组复制急性血瘀大鼠模型,并比较蒲黄生品、炭品对其血液流变性及凝血酶原时间(PT)、活化部分凝血酶原时间(APTT)、凝血酶时间(TT)、纤维蛋白原含量(FIB)的影响。结果:蒲黄及蒲黄炭均能明显降低血瘀大鼠全血高切黏度、血沉、血沉方程K、红细胞刚性指数。在凝血时间影响方面,蒲黄炭能明显缩短血瘀大鼠PT;蒲黄及蒲黄炭均能明显缩短血瘀大鼠APTT,降低其FIB,且生品作用强于炭品。结论:蒲黄及蒲黄炭均能改善血瘀大鼠异常的血液流变学指标,缩短凝血时间,降低纤维蛋白原含量而表现出一定的化瘀止血功效,蒲黄炭的凝血途径多于蒲黄生品,生品在降低FIB方面强于炭品。

Effects of Typhae Pollen and Carbo of Typhae Pollen on Hemorheological Parameters and Clotting Time in Blood-stasis Rats

Objective:To compare the effects of Typhae Pollen before and after being carbonized on the hemorheological parameters and clotting time in acute blood-stasis model of rats.Method:The SD rats were divided into control,model,Yunnan White Drug-power 0.27 g.kg-1,water extract solution of Typhae Pollen 1.2 g.kg-1,carbo water extract solution of Typhae Pollen 1.2 g.kg-1,carbo power of Typhae Pollen 1.2 g.kg-1.Except the control group,blood stasis models were established in the rest groups.The hemorheological para...
