The conditions to induce lymphokine-activated killer (LAK) cells were investigated at first. Concentrations of serum in culture media, 1, 2 and 5% had no effect on induced LAK activity. The best density of peripheral blood lymphocytes in culture bottle was 2x10^6/ml, and the most effective concentration of recombinant interleukin-2 (<@2r<@D2IL-2) to generate LAK cells was 3u/ml. Cytotoxicity against Daudi cell appeared on the second day of culture and reached a peak on the third day. There was no difference in induced LAK activity between standing and rolling culture.One patient with lung metastasis from renal cell carcinoma was treated with LAK cells and <@2r<@D2IL-2. LAK cells and <@D2r@>D2IL-2 were administered 11 times during 14 months, the first 2 times intravenously and 9 times via bronchial artery. The total number of LAK cells injected was 16.1x10<@D19@>D1 cells. Induced LAK activities gradually decreased and reached minimum at 6th treatment. From the 6th treatment plasma exchange was performed the day before administration of LAK cells. Induced LAK activities recovered from the 7th treatment. Despite these treatments the size of the metastatic lesion gradually increased.

首先研究了诱导淋巴细胞激活杀手（LAK）细胞的条件。培养基中血清的浓度，1％，2％和5％对诱导的LAK活性没有影响。培养瓶中外周血淋巴细胞的最佳密度为2x10^6/ml，重组白介素2（<@2R <@d2il-2）最有效的浓度为3U/mL。针对Daudi细胞的细胞毒性出现在培养的第二天，并在第三天达到峰值。站立和滚动培养物之间的LAK活性没有差异。一名肾细胞癌的肺转移患者用LAK细胞治疗，<@2R <@d2il-2。 LAK细胞和<@D2R@> d2il-2在14个月内施用11次，前2次静脉注射，并通过支气管动脉施用9次。注入的LAK单元的总数为16.1x10 <@D19@> D1细胞。诱导的LAK活性在第六次治疗中逐渐减少并达到最低。从第六处理中，在施用LAK细胞的前一天进行了血浆交换。从第七疗法中回收的诱导LAK活性。尽管有这些治疗，但转移性病变的大小逐渐增加。
