摘要
目的:观察西红花酸对高脂血症家兔低密度脂蛋白(LDL)氧化易感性及血清氧化低密度脂蛋白(Ox-LDL)水平的影响,并探讨其可能机制。方法:采用喂饲高脂饲料方法建立家兔高脂血症模型,ELISA法测定血清Ox-LDL水平;分离LDL,体外测定其氧化易感性;测定血清总抗氧化能力(TAC)及超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GPX)活性。结果:西红花酸能显著降低高脂血症家兔LDL氧化易感性和血清Ox-LDL水平;西红花酸30mg·kg-1能明显降低血清TC,TG,LDL-C水平,而15mg·kg-1对血脂水平无明显影响,高,低剂量组皆可显著提高血清TAC及SOD,GPX活性。结论:西红花酸能明显降低高脂血症家兔LDL氧化易感性及血清Ox-LDL水平,其机制与提高血清SOD,GPX活性、提高血清TAC有关。
