摘要:

研究了以火棉胶作为包埋材料将DNA配基固定于碳化树脂表面制备的类风湿关节炎免疫吸附剂的吸附性能,静态吸附条件下,当ssDNA的固定M在0.4mg/mL树脂时吸附性能最佳,对3种类风湿因子(RF)的最佳饱和吸附分别为IgMRF:2458IU/mL. IgGRF:2877IU/mL、IgARF:11OOIUmL.吸附120分钟后达到吸附平衡,对血浆中白蛋白及总蛋白的淸除率分别低于8%和6%,表现出较好的吸附选择性.吸附剂经毒理实验证明,使用安全性较高.对活犬进行体外血液灌流实验表明该吸附剂具有良好的血液相容性.

Abstract:

In this paper, The adsorption properties of ssDNA-carbonized resin rheumatoid arthritis immunoadsorbent were studied,Its specificity for adsorption of RF、hemocompatibility、stability and using safety were evaluated. The results show that the optimum saturation adsorption opacities of the adsorbent for IgMRF、IgGRF and IgARF were 2458、2877 and 11OOIU/mL when immobilized amount of ssDNA was 0.4mg/mL,and the ssDNA-carbonized resin is a safe and effective immunoadsorbent for RA therapy, its potential clinical use is promising in the future.

Key words: Rheumatoid arthritis, Immunoadsorbent, Adsorption properties, ssDNA, Carbonized resin
