title: The gastric secretory response to insulin: an 'all-or-none' phenomenon?
abstract: Dogs were prepared with Pavlov pouches which could be perfused with saline so as to detect rapidly changes occurring in acid secretion.Dose-response studies were performed by the intravenous injection of insulin (0.06, 0.12, 0.25, 0.5, or 1.0 unit/kg). Both the magnitude of peak response and the duration of response were dose-related and both were related to the magnitude of fall in plasma glucose. These results are not consistent with an ;all-or-none' hypothesis for insulin-stimulated gastric acid secretion, but favour the alternative hypothesis that insulin provides a graded glycopenic stimulus producing a graded secretory response.
