Effect of Yizhikang Powder on Hemorheological Indexes in Dairy Cattle with Retained Placenta

[ Objective ] The aim of the research was to reveal the mechanism of Yizhikang powder treatment on dairy cattle with retained placenta from the hemorheological perspective. [ Method] Dairy cattle with retained placenta were treated with oral administration of Yizhikang powder. And their hemorheological indexes were measured and compared with the corresponding indicators of pre-administration group, healthy group, and control group （sick but untreated）.[ Result] There was large decrease amplitude in the indexes （whole blood viscosity, plasma viscosity, whole blood viscosity reduction viscosity, ESR, ESR equation K value, fibrinogen content, platelet aggregation rate, RBC deformability IF value） of treated dairy cattle with retained placenta. By t test, the indexes, except hematocrit, decreased significantly after treatment （P〈0.05） and reached the status of post partum healthy cows. The hemorheological indexes didn＇t change significantly in the control group before and after treatment. [ Conclusion] Yizhikang powder could significantly improve blood flow state and reduced the occurrence of qi stagnation and blood stasis in perinatal period.

衣滞康散对胎衣不下奶牛血液流变学指标的影响

[目的]从血液流变学角度揭示衣滞康散治疗奶牛胎衣不下的作用机理。[方法]采用衣滞康散以口服给药方式对胎衣不下奶牛进行治疗,测定其血液流变学指标,并与给药前、健康组及对照组(患病未治疗)相应指标进行比较。[结果]用衣滞康散治疗奶牛胎衣不下后,奶牛全血比黏度、血浆比黏度、全血还原比黏度、血沉、血沉方程K值、纤维蛋白原含量、血小板聚集率、红细胞变形性IF均较治疗前显著下降(P<0.05),达到产后健康奶牛水平。而对照组处理前后血液流变学指标未见明显变化。[结论]衣滞康散可以明显改善胎衣不下奶牛的血流状态,减缓围产期气滞血淤的发生。
