β-Carotene Ameliorates Arsenic-Induced Toxicity in Albino Mice

Abstract

The present study evaluated the ameliorative potential of β-carotene (BCT) against experimentally induced arsenic toxicity in Swiss albino mice. BCT (5 and 10 mg/kg) was administered orally to mice 30 min before oral administration of arsenic trioxide (3 mg/kg) for 14 consecutive days. On 15th day, the body weights, organ weights, hematological profiles, serum biochemical profile; hepatic and renal antioxidative parameters viz. lipid peroxidation, reduced and oxidized glutathione, glutathione-S-transferase, glutathione peroxidase, glutathione reductase, superoxide dismutase, catalase; and DNA fragmentation were evaluated. Co-treatment with BCT markedly and significantly normalized body weights, organ weights, hematological profiles, serum biochemical profile and significantly modulated all the hepatic and renal biochemical parameters and DNA fragmentation in arsenic-intoxicated mice. The present findings conclude that β-carotene possessed remarkable ameliorative effect against arsenic-induced toxicity in albino mice mediated by its antioxidant and antigenotoxic properties.
