Summary:Intravenous infusion of the synthetic cholecystokinin analogue cerulein at a dose of 0.25 micrograms/kg/h causes maximal stimulation of pancreatic exocrine secretion. The infusion of supramaximal doses of cerulein (5 and 10 micrograms/kg/h) induces a significant increase in pancreatic enzymes in blood, and interstitial edema and inflammatory cell infiltration. This model of hormone-induced pancreatitis works in rats, mice, dogs and hamsters. Besides intravenous infusion, repeated intraperitoneal injections can also be used for induction of pancreatitis. In the early phase of cerulein-induced pancreatitis, large autophagic vacuoles result from fusion of zymogen granules within the acinar cell. This is accompanied by an increase in lysosomal enzyme activity and activation of trypsinogen which finally leads to cellular necrosis. All animals survive the induction of pancreatitis. The pancreas completely regenerates within 6 days after induction of pancreatitis. This model of experimental pancreatitis favors the analysis of intracellular events in the early phase of pancreatitis.
