This finding provides the clinician with a well-known and available drug which can test the proposal that the induction of a diabetictype glucose tolerance curve would provide the protective value which diabetes has against the development of duodenal ulcers.An activation of the glucoreceptor mechanism of the ventromedial hypothalmic nucleus has been proposed to be the neurophysiologic basis for the protection which the chronic hyperglycemia of adult-onset
