RESUMO
tuftsin,a physiologically active peptide,can promote phagocytosis,basically stimulates the macrophages or neutro-phils and improve their phagocytotic function.tuftsin can not di-rectly kill tumor cells.Due to its short structure and the charac-teristics of being susceptible to hydrolysis,it is difficult for tuft-sin to be made into medicine and applied clinically.However, derivatives of tuftsin-series and combination of tuftsin with other drugs can greatly enhance the cytotoxic effect on tumor cells of tuftsin.It has a broad prospect of research,especially deriva-tive-TP has a significant anti-tumor effect.Its mechanism is clear and its is expected to become a new type of anti-tumor bio-logical response regulator.
RESUMO
The immunological effects of spa bathing and its influence on the systemic performance were studied in 15 patients with stomach or colon cancer who had received operations and were treated by lentinan. Ten patients were treated by spa bathing and five patients were not treated.<br>Immunological performance was assessed in terms of white blood cell count, lymphocyte count, surface markers of lymphocytes, natural killer activity and immunoglobulins. There were no significant differences in immunological parameters between the bathing groups and non-bathing group of patients. The systemic performance improved in the majority of patients of the bathing group and became more aggravated in the majority of patients of the nonbathing group. The results of this study suggest that spa bathing is beneficial, not harmful, to the systemic performance of patients with cancer.
