[Calcitonin inhibition of insulin-stimulated gastric secretion. A possibility of selective evaluation of gastric secretory function].

There is both clinical and experimental evidence for the antigastric effect of calcitonin. A study was therefore made of gastric secretion after maximum insulin stimulation, and during its inhibition by calcitonin. Evaluation of basal acid flow and the maximum acidity peak in these two tests showed that the difference between the two peaks was related to the increase in gastrin. This was not the case during inhibition. The results show that selective evaluation of gastric secretion enables selective surgical techniques to be employed in the treatment of duodenal ulcer.
