Abstract

We examined the effects of glutathione (GSH) preconditioning through the portal vein on rat warm liver ischemia reperfusion injury (I/R injury) and investigated the mechanisms involved. In rats with warm liver I/R injury, administration of GSH by means of the portal vein before ischemia increased the 7-day survival rates of rats after liver I/R from 38% to 75%. This effect was correlated with significantly improved liver function, depressed MDA content in the liver and fewer histologic features of hepatocyte injury. Intrahepatic expression of P-selectin and infiltration of neutrophils were increased significantly after liver I/R. GSH pretreatment decreased intrahepatic MPO content and the expression of P-selectin. However, it did not significantly affect the mRNA levels for P-selectin after liver I/R. Thus, preconditioning with GSH protects the liver against I/R injury by a mechanism dependent on free radical species scavenging, down-regulation of adhesion molecule expression and inhibition of neutrophil accumulation. These findings document the potential clinical utility of GSH to improve the overall success of diverse procedures, such as liver surgery and liver transplantation.
