Chronic alcohol intake and carbachol-induced acute pancreatitis in the rat.
Alcohol-induced changes in cholinergic and pancreozymin pathways regulating exocrine pancreatic secretion have been proposed to play a crucial role in the pathogenesis of acute alcoholic pancreatitis. In the present study we investigated the role of chronic alcohol intake in an experimental acute pancreatitis induced in rats by cholinergic hyperstimulation. Chronic alcohol intake interfered with the function of rat pancreatic muscarinic receptors in carbachol-induced acute pancreatitis. However, chronic alcohol intake did not sensitize the experimental animals to cholinergic hyperstimulation. Whether this increased resistance at the level of pancreatic muscarinic receptors contributes to acute alcoholic pancreatitis is discussed in the present article.
