ABSTRACT
Objective To study the antitumour, immunomodulating and enterobacteria regulating effects of exopolysaccharides (EPS). Method The suppressive rate of growth of sarcoma 180, the index of immunity, and the intestinal microflora were determined. Results (1) EPS inhibited the growth of sarcoma 180 by oral for BALB/c mice significantly. The suppressive rate at the dose of 120mg/kg bw?d was 42.7%. (2) At the dose of 120mg/kg bw?d the index of thymus and IL-2 in serum increased significantly. There was increasing trend in respect of TNF-? and killing activation of NK cell. (3) The amounts of Lactobacillus in groups treated with EPS increased significantly, and the amounts of Enterobacteriacea and Enterococcus droped significantly. Conclusion EPS had the antitumour effect in vivo, and could modulate the immune function, improve the microbial balance in the intestinal tract of tumour bearing mice to some extent. So the antitumour mechanism was probably correlated with the immunomodulating effect.
