口服类肝素理化性质和药理活性的研究

Experimental Research of Physicochemical Properties and Pharmacological Action of a Peroral Heparinoid

  • 摘要: 目的:制备口服类肝素样品并研究其理化性质、促脂酶释放活性和抑制血栓形成作用。方法:猪十二指肠通过提取分离得到类肝素样品,采用常规方法测定其抗Xa因子活性、活化部分凝血激酶时间(APTT)活性等各项理化性质,采用比色测定法考察其促进肝脂酶(HL)和脂蛋白脂酶(LPL)释放活性,并采用大鼠动静脉旁路血栓模型考察其口服给药对血栓形成的抑制作用。结果:类肝素样品抗Xa因子活性70.4IU/mg,APTT活性33.8IU/mg,FXa/FIIa为2.1,促HL和LPL释放及抑制大鼠动静脉旁路血栓作用显著。结论:类肝素样品具有显著的促HL和LPL释放及口服抑制血栓形成作用。
