The primary objective of this study was to establish a reliable lipopolysaccharide (LPS)\u2010mediated necro\u2010hepatitis model to investigate the mechanisms of hepatic neutrophil infiltration following LPS administration. Male Sprague Dawley rats were administered a single (5 or 10 mg kg<jats:sup>\u22121<\/jats:sup>, i.v.) or repeated injection of LPS (10 mg kg<jats:sup>\u22121<\/jats:sup>, i.v., 24 h apart) with appropriate controls (i.v. saline) and were killed at various time points following LPS injection. Significant hematologic changes included neutrophilia, elevation of the neutrophil to lymphocyte ratio and toxic changes in neutrophils. Biochemical changes were observed in several liver (aspartate aminotransferase AST, gamma glutamyl transferase GGT) and kidney (blood urea nitrogen BUN) associated parameters generally at the earliest time points. Histopathology revealed a time\u2010dependent neutrophil and mononuclear infiltration around the periportal areas in the single dose study and multifocal midzonal coagulative necrosis in the repeated dose study. The neutrophil adhesion molecule, CD 11b was up\u2010regulated in single and repeat dose studies. Based on these studies, a reliable LPS\u2010mediated hepatitis model with necrosis was developed by intravenous administration of LPS in a repeat dose fashion. Midzonal hepatic necrosis, peripheral neutrophilia, hepatic neutrophil infiltration and up\u2010regulation of CD11b were the most significant and consistent markers of LPS mediated effects in this model.
