To explore the potential therapeutic effect of yttrium oxide nanoparticles (Y O NPs) on fulminant hepatic failure. RAW264.7 cells and a lipopolysaccharide/D-galactosamine-induced hepatic failure murine model were used to assess the effects of Y O  NPs. Y O NPs exhibited anti-inflammatory activity by scavenging cellular reactive oxygen species and dampening reactive oxygen species-mediated NF-κB activation . A single intraperitoneal administration of Y O NPs (30 mg/kg) enhanced hepatic antioxidant status and reduced oxidative stress and inflammatory response in lipopolysaccharide/galactosamine-induced mice. Y O NPs also attenuated hepatic NF-κB activation, cell apoptosis and liver injury. Y O NP administration could be used as a novel therapeutic strategy for treating fulminant hepatic failure and oxidative stress-related diseases.
