本文首次采用人参皂甙Rh2观察其对小鼠黑色素瘤B14的抑止作用.结果表明,人参皂甙Rh2对小鼠黑色素瘤B16.的抑止作用明显高出国家规定的指标,表明人参皂甙Rh2对小鼠黑色素瘤B16具有诱导再分化作用,这对于人参皂甙Rh2的临床研究具有重要意义.

Combinaton of CD4^＋ CD25^＋ Treg and anti-CD154 mAB inhibiting acute rejection in rat liver transplantation

Objective To investigate the effect of CD4^＋ CD25^＋ Treg combined with Anti-CD154mAb on acute rejection of rat liver transplantation. Methods CD4^＋ CD25^＋ Treg isolated from spleen of Lewis were activated ex vivo by splenocytes of DA through one-way MLR. Forty-eight cases of orthotopic liver transplantation from DA to Lewis were divided into 4 groups：
