[Hepatic resection under the Pringle maneuver induces endotoxemia and lipoperoxidative attack in the jaundiced rat liver].
Sixty percent hepatectomy under two times of the Pringle maneuver (temporal occlusion of the hepatic inflow of the hepatic artery and portal vein) for 25 min was carried out on rats with obstructive jaundice. Hepatic energy charge which was markedly decreased during the Pringle maneuver did not recover 3 hrs after release of the maneuver. In addition, systemic endotoxemia associated with increased level of malondialdehyde and decreased levels of total glutathione and alpha-tocopherol in the liver was demonstrated. These changes were more dominant in rats with obstructive jaundice for 3 weeks than those for 1 week. It can be said that deteriorated hepatic energy charge after release of the Pringle maneuver may partly be caused by the production of oxygen free radicals which may be enhanced by endotoxemia in resection of the jaundiced liver. In contrast, after release of the Pringle maneuver, deterioration of hepatic energy charge due to oxidative attack was not found in jaundiced rats without hepatic resection.
