The incidence of acetaminophen-induced hepatotoxicity is reported to be on the increase, with limited therapeutic or chemoprophylactic options. In the present in vivo study, single daily oral doses (100 – 500 mg/kg) of ascorbic acid (ASC) were investigated for their protective effects against
acetaminophen (APAP)-induced hepatotoxicity in 4 groups of rats made up of 6 rats per group for 14 days. Also, effects of the doses on body weights taken on the 1st, 7th and 15th day of the experiment were also investigated. On the 15th day, blood samples for serum ALT, AST and FBG assay were collected through cardiac puncture under inhaled diethyl ether anaesthesia. Rat livers were also studied for histopathology. Results showed that treatment with APAP intraperitoneal injection induced significant (P
