摘要
目的本研究是探讨α-玉米赤霉醇(-αZAL)在抗动脉粥样硬化(AS)作用中,对血脂代谢及血液流变学的影响。方法44只成熟未孕新西兰大耳白雌兔,分为5组,A组为正常对照组,B组为假手术组,C组为切除卵巢组,D组为切除卵巢并给予17β雌二醇(17βE2)阳性对照药组,E组为切除卵巢并给予-αZAL组。喂胆固醇(CHO)前与12周后,分别测定血清中总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白(LDL-C)、高密度脂蛋白(HDL-C)含量。还分别测定了全血黏度、血浆黏度、红细胞聚集指数(AIRC)及纤维蛋白原及血小板聚集率。结果B、D、E组TC、TG、LDL-C明显低于C组(P<0.05);全血黏度、血浆黏度、AIRC和血小板聚集率也明显低于C组(P<0.05)。结论-αZAL可能通过干预血脂代谢,调节全血黏度、血浆黏度和AIRC及血小板聚集率,改善血管功能。
Objective To investigate the effect of α-Zearalanol (α-ZAL) on lipometabolism and hemorheology in ovariectomized (OVX) hyperlipidemia rabbits. Methods 44 adult virgin female rabbits were divided into 5 groups, group A: normal control; group B: sham+CHO; group C: OVX+CHO; group D: OVX+CHO+17βE2 ; group E: OVX+CHO+α-ZAL. Cholesterol (CHO) was fed to rabbits for 12 weeks. Before and after feeding CHO, the serum lipid (TC,TG, LDL-C, HDL-C) were measured; Blood viscosity, plasma viscosity, aggregation index of RBC (AIRC) and fibrinogen were also assayed respectively. Results The serum levels of TC, TG and LDL-C in group B and E were significantly decreased compared with those in group C (P〈0.05) ; the level of blood viscosity, plasma viscosity and AIRC platelet aggregation rate in group D and E were also significantly decreased compared with those in group C (P〈0.05). Conclusion α-ZAL can improve vascular function through the adjustment of lipometabolism and hemorheology.
