title: Protective effects of syringic acid against acetaminophen-induced hepatic damage in albino rats.
abstract: The protective effect of the phenolic compound syringic acid, one of the major benzoic acid derivatives from edible plants and fruits, was evaluated against acetaminophen (APAP)-induced hepatotoxicity in rats. Toxicity was induced in adult male albino Wistar rats by the administration of APAP (750 mg/kg body weight) intraperitoneally. Rats were treated with syringic acid (25, 50, and 100 mg/kg body weight) by the oral route. We assessed the activity of hepatic markers aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, and bilirubin. Lipid peroxidative markers thiobarbituric acid reactive substances (TBARS), lipid hydroperoxides, and a decrease in enzymatic antioxidants superoxide dismutase, catalase, glutathione peroxidase, and non-enzymatic antioxidants vitamin C, vitamin E and reduced glutathione levels. Liver histology also showed convincing evidence regarding their protective nature against fatty changes induced during APAP intoxication. Syringic acid administered at a dose of 50 mg/kg body weight significantly decreased the activities of hepatic and renal function markers to near normal values when compared with the other two doses. The results suggest that syringic acid could afford a significant protective effect against APAP induced hepatic damage in rats.
