摘要: 本实验以不同类型肝素化合物降血脂性能为研究目的,采用高脂饲料喂饲小鼠成功构建高脂血症模型,并用不同剂量的肝素类物质喂养高脂血症小鼠,结果表明,不同剂量的低分子肝素、未分级肝素及多硫酸化肝素都有降低高脂血症小鼠血液中胆固醇的作用,中剂量组和高剂量组极为显著;同时,高剂量的低分子肝素可降低高脂血症小鼠血液中的甘油三酯,体重减轻明显;中剂量和高剂量组的试验小鼠肝脏中丙二醛含量显著降低,说明肝素类多糖具有一定的抗氧化能力。通过研究发现低分子肝素、未分级肝素及多硫酸化肝素三者中降血脂能力为:低分子肝素>多硫酸化肝素>未分级肝素。

关键词: 低分子肝素, 未分级肝素, 多硫酸化肝素, 降血脂性能

Abstract: The objective of this research was to investigate the hypolipidemic properties of heparin polysaccharides.The hyperlipidemia mice model were constructed by feeding with high fat diet.The results showed that different doses of low molecular weight heparin and poly sulfated heparin had significantly effects on cholesterol reduction in hyperlipidemia mice,especially the medium dose and high dose groups.In addition,high dose of low molecular weight heparin decreased the content of blood triglyceride in mice,with obvious weight loss.However,the level of MDA in medium dose and high dose groups was significantly decreased,which indicated that low molecular weight heparin strongly enhanced the capacity of antioxidant.It was found that the hypolipidemic properties of low molecular weight heparin was higher than poly sulfated heparin and unfractioned heparin.

Key words: low molecular weight heparin, unfractionated heparin, poly sulfated heparin, hypolipidemic property
