Effects of intestinal amylase and trypsin on pancreatic secretion in the pig
Abstract:
Pigs were surgically prepared with external pancreatic fistulae and duodenal cannulae in order to elucidate whether the proposed intestinal feedback control of pancreatic secretion in the pig--as in rat and man--is exerted by trypsin. Furthermore, the effect of intraluminal amylase on pancreatic secretion was studied. Reintroduction of pancreatic juice into the duodenum or infusion of trypsin into the duodenum depressed the volume of the pancreatic flow and the protein output markedly. Introduction of amylase into the duodenum did not significantly affect the pancreatic secretion. Thus, it seemed as it trypsin but not amylase was involved in the suppression exerted by pancreatic juice on exocrine pancreatic secretion in the pig.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
