Acute hemorrhagic pancreatitis in the dog. 5. The effect of antidiuretic hormone on pancreatic exocrine secretion.

Acute hemorrhagic pancreatitis was created in dogs using the closed duodenal loop technique. After 18 hours, a a constant rate of pancreatic exocrine secretion was stimulated with secretin. A direct relationship was observed between the percentage inhibition of secretin-stimulated pancreatic exocrine flow and the dose of antidiuretic hormone administered to dogs with acute hemorrhagic pancreatitis. The acute hemorrhagic pancreatitis reduced the sensitivity of the exocrine pancreas to secretin and antidiuretic hormone.
