摘要: 用均匀设计法设置6因素10水平考察了APS脂质体制备条件, 通过计算机处理结果选出适合于大规模工业化生产的最佳制备条件。APS脂质体20 ºC贮存期为1.46年。90%以上的微粒直径小于1 cm, 40 ºC放置三个月, 粒径仍未改变。通过检测APS脂质体对小鼠中性粒细胞吞噬作用, 血清溶血素水平和迟发型超敏反应的影响, 发现APS脂质体有较强的免疫促进作用。本项研究建立了APS脂质体生产和临床应用的基础。

Abstract: Six factors and 10 levels of each factor were selected by using the (uniform design method( with the aid of the computer for preparing APS liposomes. The optimal procedure for preparing APS liposomes was established and it can suit the large scale production in a pharmaceutical factory. The shelf-life of APS liposomes at 20 ºC is 1.46 years. Diameters of the vesicles (>90% ) in APS liposomes are less than 1 μm, and the system is stable. At 40 ºC the diameters of vesicles were not changed in three months. Pharmacological experiments revealed that APS liposomes exerted a strong immunoenhancement in mice. Studies in this paper established a foundation for the production and the clinical application of APS liposomes.
