Ammonia absorption from different parts of chicken intestine and its quantitative evaluation in situ.
Ammonia was more rapidly absorbed from the ileum than the jejunum, and the lower the small intestine was, the more rapid was the absorption of lumen fluid. About 95% of ammonia-15N introduced into the intestinal sac having Meckel's diverticulum in the middle part disappeared in 30 min, of which 90% was recovered as non-protein-N in the blood of the mesenteric vein draining the sac and in the mucosa of the tested portion in 30 min. About 57% of ammonia which disappeared from the intestinal lumen was found as ammonia-N and 26% as other non-protein-N in the mesenteric blood. Maximal rates of appearance of total non-protein-15N and ammonia-15N in the mesenteric blood were found within 10 min and returned to the levels at 0-5 min in 30 min.
