Edaravone’s Hepatoprotective Effects Against Oxidative Stress in Valproic acid –induced rat model

In this experimental study, the effect of edaravone (EDA) on liver damage caused by valproic acid (VPA) was investigated. The antioxidant, oxidative stress, and inflammation indicators such as glutathione (GSH), total lipid (TL), sialic acid (SA), aspartate (AST) and alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR) and glutathione-S-transferase (GST) were examined. Male Sprague Dawley rats were used in the experiment and randomly divided into 4 groups. The experiment lasted for 7 days. Group I: control group rats; Group II: rats receiving 0.5 g/kg VPA intraperitoneally daily. Group III: rats receiving 30 mg/kg EDA intraperitoneally daily. Group IV: rats receiving 0.5 g/kg VPA and 30 mg/kg EDA intraperitoneally daily (at the same time). On day 8, all animals were sacrificed under anesthesia, and liver tissues were removed. VPA caused the decreases in GSH, CAT, SOD, GPx, GR, and GST values and the increases in AST, ALT, ALP, GGT, sialic acid, and total lipid values. EDA reversed the in all values. These results suggest that EDA administration potentially reduces liver injury in VPA-induced hepatotoxicity.
