Methods:The 28 HAC-vaccinated BALB/C mice are randomly divided into control group (n=14) and acupunctrue group (n=14). In the latter group bilateral'Dazhui' (BL 11) and 'Zusanili' (ST 36) which are located according to the same positions indicated in Comparative Anatomy of Macro-animals, are needled once every day, twelve sessions altogether. Twenty-four hours after the needling treatment the mice are killed and the spleen is taken out to be made into cell suspension for assaying concentrations of IL2 (MTT method) and NKC (colorimetric method) respectively. Obital Serum IFN is determined by using (CPE microplate staining), and the tumor mass is taken out and balanced with an analytical balance (1/10000) to calculate the tumor inhibition rate according to the formula. Results: The tumor weight of the mice of aupuncture group is obviously decreased (inhibition rate 43.06%) while the activity of the IL2 and NKC, and the IFN tiler are increased greatly, which have significant differences compared with those of control group (P>0.01). Conclusion:The results of the study show that acupuncture can strengthen the positive immunoregulatory function of the IL2 -IFN-NKC network in immune hypofunction mice bearing HAC.展开更多
