20年来,国内外已从动物胸腺或血清中分离纯化出26种胸腺激素组分。但工艺复杂,丢失有效成份较多。为此,我们在有关单位配合下于1981年开始研究胸腺激素,以便寻找一种工艺简便,又不丢失有效成份的胸腺激素新制剂。材料和方法一、胸腺因子D的提取: 取新鲜成年猪胸腺制成匀浆,加两倍量酸性生理盐水搅拌抽提,清液加热至90℃15分钟去蛋白质,取清液用人工肾透析器透析,去除大分子成份收集分子 For 20 years, 26 thymic hormone components have been isolated and purified from animal thymus or serum at home and abroad. However, the process is complicated and there are many lost effective ingredients. To this end, we began researching thymus hormones in 1981 with the cooperation of the relevant units in order to find a new preparation of thymus hormone that is simple and has no loss of effective ingredients. Materials and Methods 1. Extraction of Thymic Factor D: Take the fresh adult pig thymus homogenate, add twice the amount of acidic saline, stir and extract. The supernatant is heated to 90°C for 15 minutes to remove protein, and the clear liquid is dialyzed with artificial kidney. Dialysis to remove macromolecules and collect molecules
