title: Ammonia absorption from different parts of chicken intestine and its quantitative evaluation in situ.
abstract: 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.
