摘要: 依据干扰素(IFN)分子、磷脂分子本身的理化性质和结构特点, 分别用三种制备方法, 以四种脂质体为膜材, 制备IFN脂质体, 考察了不同膜材、不同制备方法对脂质体粒径及包封率的影响. 结果表明, 以二肉豆蔻酰胆碱和二棕榈酰磷脂酰胆碱复合材料为主要膜材, 采用薄膜蒸发法制备的IFN脂质体有良好的稳定性, 60 d内其粒径可以保持在200~350 nm, 包封率可保持30%~40%.

关键词: 脂质体, 干扰素, 薄膜蒸发法, 粒径分析

Abstract: According to the physical and chemical characteristics of interferon and Lecithin, we selected four kinds of lecithin compounds as the liposomal membrane aterials, prepared liposomes by three methods, investigated liposomal shape, size distribution and the entrapment efficiency(EE) for a 60 d period to explore their influence factors of stability. The result shows the liposome made from DMMPC+DPPC+SA by film evaporation method has a good EE and size stability for 2 months. The size range is from 200 nm to 300 nm, the EE range is from 30%—40%.

Key words: Liposome, Interferon, Film evaporation method, Size distribution
