  • Title: Neutrophils contribute to ischemia/reperfusion injury in rat liver in vivo.
    Author: Jaeschke H, Farhood A, Smith CW.
    Journal: FASEB J; 1990 Dec; 4(15):3355-9. PubMed ID: 2253850.
    Abstract:
    To determine the role of neutrophils in the pathogenesis of hepatic ischemia/reperfusion injury, livers from male Fischer rats were subjected to 45 min of no-flow ischemia followed by reperfusion for up to 24 h. Two phases of liver injury were identified, an initial phase during the first hour of reperfusion and a later progression phase with 80 +/- 3% hepatocyte necrosis and an 80-fold increase of neutrophil infiltration in the liver after 24 h. Pretreatment with a monoclonal antibody against neutrophils, which caused consistent neutropenia, protected the liver from reperfusion injury as indicated by 28 +/- 10% necrosis, and 84% reduction of hepatic neutrophil accumulation and a complete recovery of the hepatic ATP content. Our data suggest that the later progression phase of reperfusion injury after hepatic no-flow ischemia is mediated mainly by neutrophils.
