Effect of the cholecystokinin-receptor antagonist lorglumide on pancreatic enzyme secretion stimulated by bombesin, food, and caerulein, giving similar plasma cholecystokinin concentrations in the dog.
This study was undertaken to determine the role of cholecystokinin in pancreatic enzyme secretion stimulated by bombesin and a meal by (a) comparing the pancreatic enzyme output during bombesin infusion and after a meal to output during caerulein infusion and (b) comparing the inhibitory effect of the cholecystokinin-receptor antagonist lorglumide (CR-1409) on enzyme output in response to bombe...

Accepted for publication 30 April 1990 Abstract This study was undertaken to determine the role of cholecystokinin in pancreatic enzyme secretion stimulated by bombesin and a meal by (a) comparing the pancreatic enzyme output during bombesin infusion and after a meal to output during caerulein infusion and (b) comparing the inhibitory effect of the cholecystokinin-receptor antagonist lorglumide...
متن کاملCholecystokinin receptor antagonism of stimulated pancreatic and gastric secretion.
The effects of cholecystokinin receptor antagonist, dipentyl-3,4-dichloroproglumide (DDP), on stimulated pancreatic and gastric secretion were studied in the rat. DDP dose-dependently inhibited cholecystokinin-stimulated amylase release from dispersed acinar cells. In vivo, DDP inhibited cholecystokinin octapeptide-stimulated amylase and protein secretion. DDP also inhibited pentagastrin-stimul...
متن کاملAntagonist-stimulated internalization of the G protein-coupled cholecystokinin receptor.
Receptor-mediated endocytosis has been observed after agonist occupation of several G protein-coupled receptors, which contributes to the desensitization response to agonist stimulation; however, the cellular signals required to initiate this process are unclear. In this study, we developed and characterized a new antagonist analogue of cholecystokinin (D-Tyr-Gly-[(Nle28,31,D-Trp30)cholecystoki...
متن کاملNovel tool for the study of cholecystokinin-stimulated pancreatic enzyme secretion.
The molecular events that mediate cholecystokinin (CCK)-stimulated pancreatic secretion are not well defined because of the complex receptor-binding and concentration-response characteristics of this hormone. Functional models of receptor occupancy initiating the cascade leading to secretion have been complicated by the inhibition of secretion effected by supramaximal concentrations of CCK. Rec...
