[Evidence of an excretion of uric acid by a caecal pouch in the rabbit (author's transl)].
Uric acid was estimated in the blood plasma, the caecal content, and in the lumen of a caecal pouch in operated rabbits. It was also histochemically detected in the caecal wall. A non negligible excretion of uric acid through the perfused caecal pouch was demonstrated. There was also an accumulation of amorphous uric acid in the enterocytes, probably due to the absence of intestinal transit, and of microorganism's uricase.
