Products of lipid peroxidation and changes in sulfhydryl compounds in pancreatic tissue of rats with caerulein-induced acute pancreatitis.

Abstract
Acute edematous pancreatitis was induced in rats by iv infusion of caerulein (CR) in a supramaximal dose of 7.5 x 10(-6)g x kg-1 x hr-1 during 6 hr. The most important finding of our study was the marked decrease of protein and nonprotein thiol content in pancreatic tissue of rats with CR-induced acute pancreatitis (AP). Oxygen radicals as well as 4-hydroxyalkenals resulting from lipid peroxidation are believed to be at least partly responsible for this phenomenon. Covalent binding of excessive amounts of 4-hydroxyalkenals to pancreatic tissue protein sulfhydryl groups has been documented. Presented data suggest a serious disturbance of sulfhydryl compounds metabolism in pancreatic tissue of rats with CR-induced AP which may be of importance in the pathogenesis of the disease.
