“ CCK-8 , CCK-33, and GIP (100 pmol/kg) all potentiated the meal-induced plasma responses of insulin and PP , whereas plasma levels of glucagon after the meal were not affected.”
“ CCK-8 , CCK-33, and GIP were all found to increase the basal plasma levels of insulin, somatostatin, and PP ; the increases were observed already in samples taken at 2 min after the injection.”
