Abstract The effects of three taste solutions on the cephalic phase of pancreatic secretion were studied in conscious dogs. Male beagle dogs weighing 9-11 kg were prepared with gastric and duodenal fistulas. Gustatory receptors were stimulated for 5 min with 100 ml of 0.5\% agar solutions containing 0.05, 0.12, and 0.3 M of either sodium chloride, sucrose, or monosodium glutamate (MSG). Pancreatic juice was collected every 5 min before and after stimulation, and volume flow and protein output were measured. Pancreatic secretory responses were found to vary with the type of taste stimulus. Sucrose was a better stimulus than MSG for both protein output and volume flow. Taste stimulation with sodium chloride produced a lower pancreatic response than those with sucrose or MSG.
