In the course of our gastric studies, we have introduced into the human stomach a considerable number of fluid substances of widely divergent character. The accompanying chart embraces data which are typical of the response secured. In the case in question, ten different fluids were introduced into the empty normal stomach, and samples of gastric contents were removed at intervals of ten minutes, until the stomach was empty, and analyzed for total acidity. It was found that the stomach contents assumed a strikingly uniform acid concentration within a half hour, entirely irrespective of the chemical character of the fluids introduced. In the case of Subject "S," whose data we have charted, the stomach contents assumed an acidity ranging from 50 to 75 in a thirty minute interval. Substances of as divergent character as vinegar, with an acidity of 190, and sodium bicarbonate, with an alkalinity of 50, were so manipulated . . . [Full Text PDF of this Article]
