    Abstract:
    D-galactosamine is a well-established hepatotoxicant that induces a diffuse type of liver injury closely resembling human viral hepatitis. D-galactosamine by its property of generating free radicals causes severe damage to the membrane and affects almost all organs of the human body. The leaves of Piper betle L., a commonly used masticatory in Asian countries, possess several biological properties. Our aim is to investigate the in vivo antioxidant potential of P. betle leaf-extract against oxidative stress induced by D-galactosamine intoxication in male albino Wistar rats. Toxicity was induced by an intraperitoneal injection of D-galactosamine, 400 mg/kg body weight (BW) for 21 days. Rats were treated with P. betle extract (200 mg/kg BW) via intragastric intubations. We assessed the activities of liver marker enzymes (aspartate amino-transferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyl transpeptidase) and levels of thiobarbituric acid reactive substances (TBARS), lipid hydroperoxides, superoxide dismutase, catalase, glutathione peroxidase, vitamin C, vitamin E, and reduced glutathione. The extract significantly improved the status of antioxidants and decreased TBARS, hydroperoxides, and liver marker enzymes when compared with the D-galactosamine treated group, demonstrating its hepatoprotective and antioxidant properties.
