  • Title: Oxygen-derived free radicals in hepatic ischemia and reperfusion injury in the rat.
    Author: Nauta RJ, Tsimoyiannis E, Uribe M, Walsh DB, Miller D, Butterfield A.
    Journal: Surg Gynecol Obstet; 1990 Aug; 171(2):120-5. PubMed ID: 2382188.
    Abstract:
    We have previously described a chronic, in vivo biochemical and histologic model of ischemia and reperfusion injury and wished to test the ability of superoxide dismutase, catalase and allopurinol to protect against the hepatocellular injury demonstrated by this model. Xanthine oxidase inhibitors given preoperatively produced a significant hepatocellular protective effect when compared with a comparable insult delivered to a cohort of control rats. The protection given seemed greater than that produced by pretreatment with free radical scavengers. Possible mechanisms for this observation are discussed. Investigations combining free radical scavengers with xanthine oxidase inhibitors may further define protection for warm hepatic ischemia and reperfusion injury.
