title: [The role of catalase in histologic changes of acute experimental pancreatitis].
abstract: We produced acute biliary reflux pancreatitis by an injection of auto-bile in 31 young mongrel dogs. We divided into control group (n = 10), catalase administration group (B1 group, n = 17) and no-administration group (B2 group, n = 14). We studied the histologic changes of the brain tissue in those groups. There was no significant difference in the survival rate between group B1 and B2. In the histologic findings, ischemic cell changes were dominant in both groups within one month, but after 3 or 6 months after operation in group B2, satellitosis and/or neuronophagia was recognized as the irreversible changes. The lipid peroxides level was significant high in group B2. Consequentially, it is natural to think that the production of free radicals have been inhibited by catalase and the histologic changes in the brain in group B1 have been light.
