Evaluation of clinical meaning of histological subtypes of intraductal papillary mucinous neoplasm of the pancreas.

abstract：:Lipid peroxidation, which may be involved in the pathogenesis of acute pancreatitis, is usually assessed in vitro or indirectly using antioxidants or free radical scavengers. We assessed lipid peroxidation in an in vivo model by measuring ethane exhalation in two models of acute pancreatitis. Edematous acute pancreati...
