摘要
淋巴细胞抑素粗提物经超滤、葡聚糖凝胶柱层析得到初步纯化,[~3H]-TdR参入试验证实SP_1可抑制淋巴细胞分裂,且含有T、B淋巴细胞抑素的活性。淋巴细胞抑素应用于小鼠骨髓移植中,可显著提高小鼠30d存活率并延长死亡动物平均存活天数,表现了对小鼠急性GVHD的抑制作用及对H-2抗原不相合骨髓移值效果的有益作用。
Lymphocyte chalone was partially purified by ultrafiltration and chromatography on Sephadex G75. Its inhibitory effect on proliferation of T, B lymphocyte was demonstrated by [3H]-TdR incorporation method. In mouse bone marrow transplantation model, the treatment with lymphocyte chalone in vivo and in vitro was found to significantly improve the 30 d survival rate and prolong mean survival time, suggesting that it has an inhibitory effect on acute GVHD and is beneficial to H-2 incompatible bone marrow transplantation in mice.
