Objective To find out the possible regularity and mechanism of the adaptable change of human being T lymphocytes for physical exercise with oxygen and bring the original data for the Movement of All People Improving their Health. Methods We selected 16 untrained female students in university and let them had the same amount of exercise for 8 weeks. After that, we collected the cycle blood at the time point of before exercise, the end of exercise and 1 hour after exercise at the end of the 0,first,2 nd,4 nd,6 nd and 8 nd week respectively, so as to determine its stimuli index (SI) by MTT method. Results In the different time sect, such as the early stage of exercise, quiet condition,as soon as the end of exercise and 1 hour after exercise, we found that the SI were obviously Iower than that of normal (P＜0. 05) ,especially in the time sect of the end of exercise. Continuing to 4 weeks,the function of T lymphocytes restored gradualy and it lasted to the 8 th week, the SI in quiet condition and 1 hour after exercise had restored to normal(P＞0.05),but in the end of exercise, it still was Iow,however, the extent of the cases selected was in a condition of acute excitability. Conclusion As the bodies adapting to the exercise, the function of T lymphocytes restored slowly and the rate increased faster and faster.

Objective To explore the pharmacological action of Bazheng mixture(BM) on infections disease of urinary system and effects of BM on immune function in mice.Methods After E.coli was injected into bladder of mice, the kidneys were examined for the anti-infection action of BM on ascending infection;and the effects of BM on immune function of mice were tested.Results BM ig remarkably decreased the percentage of kedney's infections area caused by ascending infection of E.coli [ED_(50) was(11.01?1.63)g/kg and the 95% CL was (9.50-12.76)(g/kg]);BM was also found effective in increasing the rate of carbon particle clearance and the index of carbon particle clearance,but BM had no significant effects on body fluid immunity and cell immunity in test for mice.Conclusion The mechanism of BM in treating infections disease of urinary system are mainly associated with the increasing rate of carbon particle clearance,and with bacteria clearance in urinary system.

Objective To confirm the immunomodulatory effect of ursolic acid on normal and immunosuppressive mice caused by cyclophosphamide.Methods We assayed the function of T lymphocyte transformation with MTT test,examined the function of B lymphocyte with hemolysis spectrophotography,determined the function of non-specific immunity with phagocytosis of macrophages,and measured the content changes of Th_(1) cytokine IL-2 and Th_(2) cytokine IL-6 in serum with ELISA.Results Ursolic acid had a suppressant effect on the function of humoral immunity and enhanced cell-mediated immune response at the low dosage but presented opposite effect at the high dosage in normal mice.Ursolic acid significantly improved immune function on immunosuppressive mice caused by cyclophosphamide(P

Objective To explore the influence of chronic neuropathic pain on cellular immune function of mice models.Methods The mice models were established by ligating tibeal nerve and common peroneal nerve on one side,and the influence of chronic neuropathic pain on cellular immune function and tumor necrosis factor-?(TNF-?) and interleukin-6(IL-6) was observed with lymphocyte cell increase experiment(MTT method) and enzyme linked immunosorbent assay(ELISA).Results The increased reactivity of T lymphocyte of the model group was significantly higher than that of the sham group and the control group.At the same time,content of TNF-? and IL-6 in blood of the model group also increased.Conclusion Cellular immune function of mice is increased in the state of chronic neuropathic pain.
