A common pathway in the pathogenesis of acute pancreatitis is the generation of free oxygen radicals. The most important defense mechanisms are free radical scavengers, especially glutathione. This study evaluates the influence of the inhibition of glutathione synthesis with L-buthionine-(S,R)-sulfoximine (BSO) on the course of experimentally induced acute pancreatitis in rats and the effects on isolated pancreatic acini and their secretion pattern. Thus acute necrotizing pancreatitis was induced with intraductal infusion of low-dose glycodeoxycholic acid and subsequent hyperstimulation with cerulein with and without pretreatment with BSO. In vitro pancreatic acini were isolated and stimulated with different concentrations of cerulein with and without BSO. The BSO-treated group showed a significantly reduced survival, more necrosis, and a decreased secretion of amylase in vivo. No effect on secretion pattern in either groups was seen in vitro and BSO did not exert toxic effects. Based on the data presented, this study demonstrates deleterious effects of scavenger depletion on the course of experimental pancreatitis. This is due to the systemic effects of free oxygen radicals rather than to local effects.
