Abstract
If the gastric mucosa of the living dog is exposed for a short time to from one to two per cent, of glycerin in water, the gastric secretion which follows is not more intense than after water alone. Three years ago I observed this experimentally in the Laboratory of the Pathological Institute of Berlin, and last year it was confirmed by Rodari. In experiments with stronger concentrations of glycerin, especially if allowed to enter the duodenum, the gastric secretion which follows is less than after pure water. Glycerin furthermore not only reduces the gastric secretion incited by water, but inhibits even a subsequent secretion of the stomach provoked by sham-feeding. This I have observed in an experiment on a dog with sham-feeding; the influence of glycerin on the human stomach does not appear to have been the subject of study.
