产后健康奶牛血液流变学主要指标测定及其意义

Dynamic Change of Main Hemorheological Parameters of Dairy Cows During Puerperium Period(1-30 d)

为了解产后健康奶牛血液流变学的变化规律 ,验证“产后血瘀”这一传统生理观的客观存在 ,对 18例奶牛产后期(产后 1～ 30 d)血液流变学的全血比粘度高、低切 (η b80 s- 1 、η b2 0 s- 1 ) ,血浆比粘度 (η p) ,红细胞压积 (PCV) ,全血还原比粘度高、低切 (η r80 s- 1 、η r2 0 s- 1 ) ,红细胞聚集指数 (AI) ,红细胞刚性指数 (IR) ,血浆纤维蛋白原含量 (FG)等 9项指标进行了系统检测。结果表明 ,产后 15、30 d与新产时 (产后 1～ 7d)比较 ,除 AI、η r2 0 s- 1外 ,其余 7项指标至少在某一时间段呈现差异极显著或显著 (P<0 .0 1或 P<0 .0 5 )。本试验从血液流变学的角度初步揭示了母畜“产后血瘀”

Main hemorheological parameters of 18 healthy dairy cows during puerperium period(1-30 d) were measured and analyzed with the basical change regulation or general trends of whole blood specific viscosity high ratio and low ratio(η b80 s -1,η b20 s -1),plasma specific viscosity(η p),packed cells volume(PCV),relative viscosity high ratio and low ratio of the whole blood(η r80 s -1,η r20 s -1),aggregation index of RBC(AI),rigid index of RBC(IR),fibrinogen contents(FG) to be described.The results showed:7 out of the 9 hemorheological parameters(except AI,η r20 s -1) 15 d,30 d had significantly difference than that of 1-7 d some time.Thus verified the objective reality and regularity of the hypothesis 'There existing blood stasis syndrome during puerperium period' form dynamic change of the hemorheological parameters.
