Preventive efficacy of butyrate enemas and oral administration of Clostridium butyricum M588 in dextran sodium sulfate-induced colitis in rats.

Butyrate enemas have been reported to be effective in ulcerative colitis. However, long-term use is difficult because of the troublesome procedure and the unpleasant smell. We therefore investigated the effects of the oral administration of Clostridium butyricum M588 (CBM588), an enterobacterium producing butyrate, in dextran sodium sulfate (DSS)-induced colitis in rats. First, we confirmed the effects of pre-treatment with a butyrate enema on DSS colitis. We then studied the efficacy of oral administration of CBM588 which was started 1 week prior to the induction of DSS colitis. In the CBM588 group, the ulcer index and myeloperoxidase (MPO) activity in the distal colon were significantly lower than in the control group. Proliferating cell nuclear antigen (PCNA) immuno-positive cells were increased around the ulcer in the CBM588 group. In regard to the contents of the cecum and colon, the proportions of Lactobacillus and Eubacterium were increased in the cecum in the CBM588 group. Further, there were significant increases of n-butyrate, propionate, and acetate concentrations in the cecum in the CBM588 group. These results indicated that the oral administration of CBM588 alleviated DSS-induced colitis, and may be useful instead of butyrate enema.
