Oxidative stress and inflammation are two major etiological factors that are suggested to play key roles in the development of ethanol induced liver injury. Release of proinflammatory cytokine like tumor necrosis factor alpha (TNF-α) and activation of nuclear factor kappa-B (NFκ-B) may strongly intensify inflammation and cell damage. Additionally, reactive oxygen species (ROS) also exerts significant effect in this whole cell signaling machinery. The present study was designed to investigate the protective effects of perillyl alcohol (POH) on ethanol-induced acute liver injury in Wistar rats and its probable mechanism. We have successfully demonstrated that pre-treatment with POH, besides exerting antioxidant activity might be able to modulate TNF-α release and NFκ-B activation. Rats were divided into five groups and treated with ethanol or POH via an intragastric tube for one week. Control group was treated with …
