作者利用裸鼠肾被膜下移植检测法(SR-CA)研究体内局部应用淋巴因子激活的杀伤细胞(LAK)对头颈肿瘤的作用。将肿瘤细胞株与效应细胞混合后植入裸鼠肾被膜下,与未混有效应细胞的对照组比较肿瘤生长速度和裸鼠存活时间。效应细胞取自正常自愿者,通过 The authors used the nude mouse subrenal transplantation assay (SR-CA) to study the effect of locally applied lymphokine activated killer cells (LAK) on head and neck tumors. The tumor cell line and the effector cells were mixed and implanted under the renal capsule of the nude mice, and the tumor growth rate and the survival time of the nude mice were compared with the control group without the effector cells. Effector cells are taken from normal volunteers and passed
