The Effect of Lymphocyte Chalone on Bone Marrow Transplantation in Mice / 第二军医大学学报

ABSTRACT

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.
