目的：观察莪术对正常和血瘀证孕大鼠血液流变学的影响。方法采用皮下注射盐酸肾上腺素与冷刺激的方法制备血瘀证模型，造模后将正常组随机分为空白对照组和高、中、低剂量莪术组，将血瘀证模型组随机分为模型对照组和高、中、低剂量莪术组。受孕后第6～19 d给予不同剂量的莪术水煎液。检测受孕雌鼠血液流变学指标。结果莪术高、中、低剂量组均能降低正常组与血瘀证模型组在不同切变率下全血黏度。与正常对照组相比较，正常＋莪术高剂量组在不同切变率下全血黏度有显著性差异（P＜0．05），而在中切变率下，各剂量血瘀＋莪术组的全血黏度与正常对照组相比较均有显著性差异（P＜0．05）。结论莪术＋血瘀证模型组能使全血黏度降至正常孕大鼠水平，证明了中医“有故无殒，亦无殒”的中药辨证减毒理论。%Objective This study aims at evaluating the effect of curcumae rhizoma on hemorheological parameters between normal and blood -stasis pregnant rats .Methods A model of blood -stasis in rats was established by injecting adrenalin and being immersed in ice water .Normal Wistar female rats were randomly divided into blank control group and low , medium and large dose curcumae rhizoma groups , blood-stasis model rats were divided into model control group , low, medium and large dose curcumae rhizoma groups .Curcumae Rhizoma was orally administered to pregnant rats from gestational day ( GD) 6 through 19 at different doses .The hemorheological parameters were used to monitor the pregnant rats .Results Curcumae rhizoma could significantly reduce the hemorheological indexes in whole blood viscosity .Compared with normal group , whole blood viscosity at high , middle and low shear rate were decreased in rats of normal group treated with Curcumae Rhizoma(P<0.05), and We only could find blood viscosity changes at middle shear rate in blood -stasisrats rats treated with curcumae rhizoma(P<0.05).Conclusions Blood-stasis pregnant rats treated with curcumae rhizoma group can make the whole blood viscosity reduce to a normal level , and it proved the traditional Chinese medicine theory .
