5-LO specific inhibitor AA-861 prevented hepatocellular necrosis in D-GalN/LPS-treated rats. Representative photomicrographs of liver sections stained with hematoxylin and eosin from the control group receiving placebo (left panels), 24 hr D-GalN/LPS-treated rats receiving placebo (middle panels), and 24 hr D-GalN/LPS-treated rats receiving AA-861 (right panels). Confluent necrosis score and spotty lytic necrosis, apoptosis, and focal inflammation score in Modified Histological Activity Index system were employed. Control: 0; D-GalN/LPS: 9; AA-861 + D-GalN/LPS: 2.
