Conclusions
These experiments show the following effects of insulin on the motility of the stomach.
1. In the normal animal the administration of insulin accelerates the motility of the stomach.
2. In the bilaterally vagotomized animal there is a greater inhibition of gastric motility, exceeding that observed after bilateral vagotomy without insulin.
3. In addition to the gastric motility inhibition, insulin further diminishes the gastric tone and causes an increased gastric retention and greater dilatation of the stomach than that observed following bilateral vagotomy without insulin.
4. It would appear that the effects of insulin are mediated through the vagus nerves.
Finally it is suggested that on the basis of the data presented, a roentgen insulin test for the determination of vagotomy could be developed.
