ABSTRACT

Objective To explore the protective effect of resveratrol on rat brain injury resulting from severe acute pancreatitis (SAP). Methods Ninety-six male Sprague-Dawley rats were randomly divided into four groupssham-operation (SO) group,severe acute pancreatitis (SAP) group,resveratrol-treated (RES) group and dexamethasone-treated (DEX) group,with eight rats in each group evaluated at 3,6 and 12 h. Levels of serum myelin basic protein (MBP),tight junction protein zonula occludens 1 (Zo-1),TNF-? and IL-6 were determined by ELISA. The ultrastructural changes of the brain and pancreatic tissues were examined using a transmission electron microscope. Results MBP,Zo-1,TNF-? and IL-6 levels in RES group were lower than those in SAP group at all time points (P0.05). Conclusion The degradation of Zo-1 is involved in the pathophysiology of brain injury in SAP; MBP can be used as a marker of brain injury in SAP rats. Resveratrol can inhibit brain injury associated with SAP.
