中文摘要:
      目的 比较生、熟大黄及其入下瘀血汤对热结血瘀模型大鼠的血液流变学的影响,以阐释生大黄泻热通便、熟大黄活血化瘀的炮制作用。方法 采用ig热性中药结合sc盐酸肾上腺素的方法,复制大鼠热结血瘀模型,再ig不同剂量的生、熟大黄以及生、熟大黄组成下瘀血汤,观察对模型大鼠血液流变学的影响。结果 熟大黄各剂量组与等剂量的生大黄相比,其血液流变学的各项指标检测值均有所改变,其中熟大黄高剂量组全血黏度、红细胞刚性指数与变形指数(TK)与生大黄相比,差异具有显著性(P<0.01);熟大黄复方组与等剂量生大黄复方组比较,其血液流变学的各项指标也有明显改变。结论 熟大黄的活血化瘀作用强于生大黄,大黄炮制后可增强其活血化瘀作用。
英文摘要:
      Objective To clarify the effects of raw and stewed rhubarb and Xiayuxue Decoction on hemorheological parameters in rats with heat accumulation of blood stasis by comparing the influence of them on purgative and promoting blood circulation. Methods The rat model with heat accumulation of blood stasis was established by ig administration with heat Chinese medicine and sc injection with adrenaline hydrochloride. At the same time, raw and stewed rhubarb and Xiayuxue Decoction at different doses were given. Then the hemorheological parameters of the rats were observed and compared. Results Compared with the same dose of raw rhubarb, the stewed rhubarb changed each hemorheological parameter and there were extremely significant differences in whole blood viscosity, erythrocyte rigidity index, and erythrocyte deformation index (TK)between raw and stewed rhubarb at high dose (P < 0.01). There were differences in hemorheological parameters of complex prescription with raw and stewed rhubarb at the same dose. Conclusion The efficiency of stewed rhubarb on promoting blood circulation to remove blood stasis is definitely better than that of raw rhubarb, and processing of the raw rhubarb could strengthen the effect of promoting blood circulation to remove blood stasis
