To evaluate the effect of intraperitoneal hyperthermo-chemotherapy (IPHC) on immunologic function of patients with gastrointestinal malignant tumor (GMT). The authors determined the serum T-lymphocyte subsets (T-LS) and interleukin-2 receptor (sIL-2R) of 32 patients with GMT after IPHC, and compared the two indexes with 20 healthy control group. Results: Before IPHC the serum CD＋3, CD＋4, CD＋8 and CD＋4/CD＋8 were higher and sIL-2R were lower than control group, after IPHC, CD＋3, CD＋4, CD＋8 and CD＋4/CD＋8 increased obviously (Ｐ＜0.01) and the serum sIL-2R decreased significantly (Ｐ＜0.01). Conclusion: The IPHC can improve the patients immunologic function.
Objective To study the effects of edaravone on the lung injury of severe acute pancreatitis （SAP） in rats. Methods Thirty-six SD rats were randomly divided into three groups: normal control group, model group and edaravone group, and SAP was induced by intraductal administration of 5% sodium taurocholate. Edaravone was given in edaravone group, while normal saline was given in normal control group and model group. After operation 6 h rats were executed, and dry/wet weight (D/W) ratio of lung was counted, and malondialdehyde (MDA) content, superoxide dismutase (SOD) activity in serum and lung were detected, respectively. In addition, the levels of tumor necrosis factor-α (TNF-α), interleukin-1, -6 (IL-1, -6) of serum were detected.Results The MDA contentof serum and lung and the levels of TNF-α, IL-1, IL-6 in model group were markedly higher than those in normal control group and edaravone group, but D/W ratio of lung, SOD activity of serum and lung were significantly lower (Plt;0.05). Conclusion Edaravone can alleviate lung injury of rats caused by SAP.
