Abstract： 目的 探讨沙利度胺体外对人类非霍奇金淋巴瘤(NHL)Raji细胞血管内皮生长因子(VEGF)的影响及其作用机制.方法 采用MTT法检测沙利度胺对人类NHL Raji细胞是否有抑制作用,采用ELISA法检测沙利度胺作用前后Raji细胞上清液中VEGF含量的变化.结果 MTT法示沙利度胺体外对人类NHL Raji细胞无直接的抑制作用(P＞0.05).ELISA法示10、25、50 mg/L的沙利度胺组对Raji细胞分泌VEGF均有明显抑制作用(P＜0.05).5 mg/L沙利度胺组及0.1%DMSO对照组对Raji细胞分泌VEGF无明显抑制作用(P＞0.05).沙利度胺对Raji细胞分泌VEGF的抑制作用随着浓度和时间的递增而增加.结论沙利度胺能够抑制人类NHL Raji细胞分泌VEGF并且存在时间和浓度依赖性.沙利度胺体外对Raji细胞并无明显直接的抗增生效应与细胞毒活性.
