In this paper, moxibustion and nonmoxibustion treatments were given to the Tachui (DuI4) of 106 cases nomal mice and cyc1ohosghamide treated mice, the effect of moxibust ion on phagocyte ic function of mouse phagocyte were observed based on changes of percentage of phagocytos is and phagocyte ic index. The results were as follows, Moxibustion Tachui could increase phagocyte ic function of mouse phagocyte in both nomal mice and cyclophosphamide treated mice, but moxibustion had more remarkable effect in cyclophsphamide treat mice. The experiment suggested moxibustion had effect on regulating balance.
