Summary:
Activation of zymogens within the pancreatic acinar cell is an early feature of acute pancreatitis. Supraphysiologic concentrations of cholecystokinin (CCK) cause intrapancreatic zymogen activation and pancreatitis. Supraphysiologic concentrations of CCK also cause zymogen activation in isolated pancreatic acini. This activation first occurs in a nonzymogen granule compartment that contains lysosomal markers. A low pH environment may also be needed for activation. To examine the ability of alcohols to sensitize the acinar cell to CCK, the conversion of zymogens to active enzymes in isolated acini was assayed. Alcohols, including 35 mmol/L ethanol, sensitized acini to CCK induced activation. The sensitization increased with chain length and was less in branched compared with unbranched alcohols. The relationship of alcohol's structure to sensitization may be related to the mechanism of sensitization.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
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:
