Abstract
Oxidative stress is considered to be a pathogenic factor for multisystem organ failure during acute pancreatitis. Infusion of 3% and 5% sodium taurocholate into the pancreatic duct of rats resulted in a 24-hr lethality of 8% and 82%, respectively. Kidney tissue showed a long-lasting significant elevation of malondialdehyde (lipid peroxidation). Only small amounts of this aldehyde were formed in the liver. In the lung malondialdehyde was increased during the first 6 hr after pancreatitis induction. Malondialdehyde levels were not different for pancreatitis initiated by 3% or 5% taurocholate. Protein-bound carbonyls (protein oxidation) in the tissues were not significantly changed at any time point. However, after infusion of 5% taurocholate, lung proteins were oxidatively modified by the product of lipid peroxidation, 4-hydroxynonenal. Another parameter characteristic for pancreatitis with high lethality was the high number of neutrophils in the lungs. We conclude that oxidative stress is important for the injury of extrapancreatic tissues during pancreatitis, but survival is determined by the degree of systemic inflammation.
