Heidenhain, by employing the antiseptic method, was able to preserve three dogs out of seven thus operated on. He also succeeded in isolating in the same manner the cardiac extremity of the stomach by means of this operation ; therefore, it is rendered possible to obtain pure gastric secretion from either the pyloric or the cardiac extremity of this organ, and the characters of the secretions from these parts are rendered accessible for study. In order to collect gastric juice for analysis the dog must be allowed to fast for at least twenty-four hours, so as to empty the stomach, and the secretion of gastric juice may be stimulated by tickling the inner surface of the stomach with a feather tied to a glass rod. The gastric juice will then flow along the glass rod out of the stomach, and may be col- lected in a glass beaker. Bernard's method of stim- ulating the flow of gastric juice was to give a dog which had been fasting for some time a hearty meal of thoroughly boiled tripe, which furnished a normal stimulus to the gastric glands, and, being almost indi- gestible, does not contaminate the gastric juice to any great extent, and is there- fore in some respects preferable to mechanical stimulation. That the gastric juice may be obtained perfectly pure, the salivary ducts should be tied, otherwise the fluid obtained from the stomach will be more or less mixed with the Fig. 147.—Gastric Fistula. {Bernard.)
