Abstract
In vivo influence of butyrate in colonic mucosa was studied using a model of gnotobiotic rats monoassociated with a Clostridium paraputrificum. Rats were fed a diet containing increasing amounts of non-digestible carbohydrates, the fermentation of which led to modulated amounts of butyrate in the large intestine. In the proximal colon, the increase in the butyrate concentration alters crypt depth and the number of mucus-containing cells; the increase in butyrate was highly correlated with the number of neutral-mucin-containing cells. Conversely, in the distal colon, no relation was found between the increase in butyrate concentration and crypt depth or number of mucin-containing cells. In both the proximal and distal colon, the mitotic index remained unchanged. In conclusion, in vivo production of physiological quantities of butyrate had a trophic effect on proximal colonic mucosa, but did not influence the distal epithelium.
