Abstract
Acute haemorrhagic pancreatitis was produced in the dogs by transduodenal injection of autologous bile into the main pancreatic duct. There was no significant change in the activity of three regulatory enzymes of phosphatidylcholine biosynthesis (glycerophosphate acyltransferase, cytidyltransferase and cholinephosphotransferase) in lung; however, there was a 42% decrease in the amount of dipalmitoyl phosphatidylcholine (surfactant) in lung lavage due to acute pancreatitis. The decrease in lavage phospholipid content was associated with (a) 5-fold increase in phospholipase A 2 activity of lung lavage, and (b) massive accumulation of osmiophilic spheriod structures in the alveolar space.
