N/A Application of adoptive immunotherapy has been the inability to generate specifically sensitized lymphoid cells with antitumor reactivity. Interleukin-2 is now available in large quantities and has made possible expansion of cells with a diverse spectrum of immune reactivities. In this study, we evaluated the immunologic effects and the response rate of LAK cell, Interleukin-2 and cyclophosphamide administered intravenously in humans with tumors unresponsive to other treatments. There were five hepatomas and a metastatic breast cnacer. Two patients received LAK cell and Interleukin-2 twice. 5.94x10 monounclear cells were obtained in each leukapheresis. Cellular cytotoxicity was measured using 51 Chromium release assay. This study clearly showed that Interleukin-2 and Cyclophosphamide treatment augmented LAK cell activity, but there were no statistically significant differences in the natural killer cell function after the treatment. There were one complete response and one partial response. It could be speculated that LAK, Interleukin-2 and Cyclophosphamide therapy can be used as an adjuvant treatment for the advanced cancer.

전왜재질 0.9 PMN/0.1 PT에 각각 조성비율이 1%, 2%, 3%의 La이 첨가된 3종류의 재질을 광섬유에 부착하여 광섬유 전왜변환기를 제작하였다. 실험결과 La 3% 첨가된 재질의 전왜계수가 3.38㎑에서 3.87×10^(-16)(m/V)²로 가장 크다는 것을 알 수 있었으며 La을 첨가함으로 해서 이력이 줄어듬을 알 수 있었다. La 3%인 재질로 구현된 광섬유 전계센서의 최소감지전계는 2.08(V/m)/√㎐였으며 가변영역 40㏈ 이상에 걸쳐서 선형성이 우수하였다. We report a fiber optic interferometric electric field sensor that utilizes electrostrictive ceramics-1%, 2%, 3%, La-doped 0.9PMN/0.1PT, respectively-as the transducing elements. It is also experimentally observed that 3% La-doped PMN/PT among the three elements has the largest electrostrictive coefficient M=3.87×10^(-16)(m/V)² at 3.38 ㎑ and displays small hysteresis. The optical fiber sensor with the 3% La-doped PMN/PT exhibits minimum detectable field of 2.08(V/m)/√㎐ and has a good linearity over the dynamic range 40 ㏈.
