title: [An experimental study of the antitumor activity of tumor-infiltrating lymphocytes (TIL) in human tongue carcinoma in vitro].
abstract: In the present paper tumor-infiltrating lymphocytes (TIL) from lymph nodes of human tongue carcinoma patients were obtained by discontinuous density gradients centrifugation and used in experimental treatment. The results showed that 1.3 x 10(8) TIL/g lymph node tissue were gotten by the above method. TIL activated by rIL-2 exhibited higher cytotoxicity to Tca8113 cell line than the same patient's LAK cells (81.48% and 24.69% respectively). There was significantly difference in the cytotoxicity between two groups (P < 0.01), indicating that TIL were the best source of adoptive immunotherapy.
