title: [Ammonia in the intestinal contents from germfree rats].
abstract: The values of pH and the concentrations of nitrogen (N) and ammonia in the middle part of the small intestinal and cecal contents of germfree (GF) and conventionalized (CVZ) seven-week-old rats were compared. The pH of the small intestinal and cecal contents of GF rats was higher than that of CVZ rats. There was no difference in total N per fresh weight in contents from the middle part of the small intestine between GF and CVZ, whereas total N per fresh weight of the cecal contents was higher in CVZ than in GF rats. The ammonia concentrations per fresh weight or per total N in the intestinal and cecal contents of CVZ rats were higher than those of GF rats.
