摘要: 为了观察甘草次酸被脂质体包封后其免疫增强作用的变化,选取100只小鼠,随机分成4组,分别用含有甘草次酸脂质体(GAL)、甘草次酸(GA)、空白脂质体(BL)和油佐剂(OIL)的卵清蛋白(OVA)免疫小鼠。采用ELISA法测定用OVA免疫的小鼠血清中免疫球蛋白IgG及细胞因子IL\|2,IFN\|γ的浓度变化;采用MTT法测定脾淋巴细胞的增殖。结果表明,GAL能显著增加IgG,IL\|2和IFN\|γ的浓度,促进淋巴细胞增殖,且效果好于GA,BL或油佐剂。表明GA经脂质体包封后,二者可协同增强免疫。

Abstract: In order to study the action mechanism of glycyrrhetinic acid liposome (GAL) , 100 mice were vaccinated by ovalbumin along with glycyrrhetinic acid liposome (GAL), glycyrrhetinic acid (GA), liposome (BL) or oil (OIL) in four groups. Blood samples were collected to measure antibody titers, IL\|2 and IFN\|γ by ELISA assay; cell mediated immune response was detected by MTT assay. The results showed that GAL could improve the secretion of IgG, IL\|2 and IFN\|γ, and significantly promote lymphocyte proliferation in comparison with glycyrrhetinic acid, liposome and oil. The present study demonstrated that the activity of glycyrrhetinic acid encapsulated with liposome was enhanced.
