2、杀伤活性的CIK细胞。CIK、顺铂及CIK联合顺铂分别作用A549细胞24、48h,MT/"法检测细胞吸光度(A)值并计算各组细胞杀伤率。完全培养液培养CIK48h后,取上清液,按1:l稀释后与A549细胞共培养24h,用流式细胞仪检测A549细胞凋亡率。结果CIK、顺铂对A549的杀伤活性呈时间、剂量依赖性(P<0.05)。5g/mL顺铂联合效靶比为10:1、20:1的CIK共同作用A549细胞24h,A549的杀伤率(%)分别为53.80±6.81,61.17±3.82,与单用顺铂及CIK相比,其对A549的杀伤率显著升高(P<0.05)。CIK上清液可诱导A549
3、细胞凋亡。结论CIK可增强顺铂对A549细胞系的杀伤作用。关键词:肺肿瘤;肺腺癌细胞株;细胞因子诱导的杀伤细胞;顺铂中图分类号:R734.2文献标志码:ACIKmayenhancethelethalefectofcisplatinonthelungadenocarcinomacelllineA549LIDan。,LIChong“,ZHANGlie—xin,WANGZhi—gang。,XUBin,DENGHai-feng,LUMing—yn,LIMin,ZHOU,SUNQ,L,uJian,ZHENGXiao,JIANGJing—ting(a.DepartmentofRes
