摘要
作者采用 ̄51Cr4h释放试验和裸鼠移植瘤模型,从颈淋巴清除术后标本中制取肿瘤引流区淋巴结细胞(DNL),经体外激活后与自身LAK细胞比较对人舌鳞癌细胞系Tca8113细胞体外、体内的杀伤活性,结果显示:E:T为25:1时,DNL组体外杀伤率为65%,LAK组为28%,按Winn氏中和法分别将DNL,LAK细胞同Tca接种于裸鼠皮下,结果DNL组抑瘤率为74%,LAK组为42%,经统计学分析两组间存在显著性差异(P<0.05),提示DNL细胞杀瘤活性明显强于LAK细胞,且来源容易,与传统的LAK细胞比较在癌过继免疫治疗中有较高的实用价值。
AbstractThe in vitro and in vivo antitumor activrty be-tween DNL and autologous LAK cells was compared.The resuhs showed that DNL cells activated in vitroby rIL-2 exhibited higher cytotoxicity to Tca 8113cells than the same patient's LAK cells (75% and36% , respectively). According to Winn's method,the inhibition rates of subcutaneously transplantedTca cells in mice were 74% and 42% respectively.There was significantly difference in the antitumor ac-tivity in vitro and in vivo between two groups (P<0. 003 , indicating that DNL cells which are moreavailabe are more practicable for adoptive im-munotherapy.
