ABSTRACT

Oxymatrine, a quinolizidine natural drug extracted from Sophora japonica, has been reported to have neuroprotective effect and cardioprotective effect. However, the protective effect of oxymatrine on arsenic trioxide (As2O3)-induced liver injury has not been reported. In the present study, we investigated the protective effects of oxymatrine on As2O3-induced liver injury in rats. Male Wistar rats were administrated 3mg/kg As2O3 intravenous injection on alternate days for 4 days. Oxymatrine was given 1 h before As2O3 treatment. The results showed that oxymatrine inhibited As2O3-induced hepatic pathological damage, liver ROS level and MDA level in a dose-dependent manner. As2O3 decreased the antioxidant enzymes SOD, GPX, and CAT activity and the decrease was inhibited by treatment of oxymatrine. Furthermore, oxymatrine attenuated the retention of arsenic in liver tissues and improved the expression of Nrf2 and HO-1. In conclusion, our results suggested that oxymatrine protected against As2O3-induced oxidative damage by activating Nrf2/HO-1 signaling pathway.
