Serum neurotransmitter, negative emotions and immune index levels were compared between the two groups of subjects. Pearson test was used to evaluate the relationship of serum neurotransmitter contents with negative emotions and immune index levels in patients with lung cancer chemotherapy. Results: Serum neurotransmitters DA, 5-HT and NE contents in observation group were lower than those in normal control group;SAS and SDS scores were higher than those of normal control group;peripheral blood CD4+T lymphocyte level, CD4+/CD8+ ratio and NK cell level were lower than those in normal control group while CD8+ T lymphocyte level was higher than that in normal control group. Pearson test showed that serum neurotransmitters DA, 5-HT and NE contents in patients with lung cancer chemotherapy were directly correlated with anxiety depression, T lymphocyte subset and NK cell levels.Conclusion: Serum neurotransmitter expression decrease in patients with lung cancer chemotherapy, and this is one of the important causes of anxiety depression and immune dysfunction in patients.展开更多

Indeed, both TX and TO stimulated cells mediated cytotoxicity reactions by various killer cells: killer T (TK), natural killer (NK), lymphokine activated killer (LAK) cells. Both TX and TO inhibited the growth of tumors that express estrogen receptors. Thus these antiestrogens inhibited tumor growth and stimulated killer cells for cytotoxicty on such tumors. Therefore these agents were presumed to stimulate tumor immunity. We tested the P815 mouse mastcytoma with TK, LK, and TX or TO. A therapeutic effect was observed in both experiments. The SL2-5 murine lymphoma was tested with NK and TX cells or TO cells and successful immunotherapy was observed.?We digested human breast carcinomas and lung tumors with collagenase. The killer cells were separated from tumor cells on Ficoll gradients. TX and TO enhanced the cytotoxic effect of autologous killer cells on the corresponding tumor cells. This experiment indicates that the results obtained in animals are also valid for human malignant disease.展开更多
