Inhibitory effect of curcumin on liver injury in a murine model of endotoxemic shock

The effect of curcumin on lipopolysaccharide/d-galactosamine (LPS/GalN)-induced acute shock model of liver injury was examined in mice. The simultaneous administration of LPS (5–20 μg kg−1, i.p.) and GalN (700 mg kg−1, i.p.) markedly increased the serum tumor necrosis factor-α (TNF-α), glutamic oxaloacetic transaminase/glutamic pyruvic transaminase (GOT/GPT), and massive hepatic necrosis and inflammation, leading to 100% lethality. Pre-administration of curcumin (100 mg kg−1, i.p.) 3 h before induction with LPS/GalN imparted a large extent of protection against acute elevation in serum TNF-α and serum GOT/GPT. Hepatic necrosis and lethality caused by LPS/GalN was also greatly reduced by curcumin treatment. The results demonstrated that curcumin could protect mice from LPS/GalN-induced hepatic injury and inflammation through blockading TNF-α production, eventually raising the survival rate of septic-shock-induced mice.
