Spontaneous and cholecystokinin-octapeptide-promoted regeneration of the pancreas followingl-arginine-induced pancreatitis in rat

Abstract
Inl-arginine (Arg)-induced pancreatitis, evidence of acute inflammation was observed on d 1–3. Continuous tissue atrophy became visible at the sites of previous pancreatic necrosis, with simultaneous regeneration of the pancreas, mainly around the Langerhans islets. Administration of low doses of cholecystokinin-octapeptide (CCK-8) increased the inflammatory signs of pancreatitis in the early phase, but subsequently diminished the level of atrophy and accelerated the processes of regeneration in this model of pancreatitis.
