Cadmium and its compounds have been classified as known human carcinogens. Telfairia occidentalis is a medicinal plant with a number of pharmacological activities attributed to its extracts. This study was designed to investigate the possible hepatoprotective effect of aqueous extract of Telfairia occidentalis on cadmium chloride (CdCl2) induced oxidative stress and hepatotoxicity in experimental animals. Twenty-four (24) adult male rats were divided into 4 groups of 6 rats each. Group I received distilled water, group II, III, and IV were administered 5mg/kg body weight CdCl2, group III, IV were treated with 200 and 400mg/kg body weight (bw) respectively of aqueous extract of Telfairia occidentalis for 14 days. Results obtained showed that exposure of rats to cadmium induced hepatocellular injury as demonstrated by significant increased (P<0.05) in activities of Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Acid phosphatase (ACP) and alkaline phosphatase (ALP). Lipid peroxidation was induced as shown by significant increase (P<0.05) in malondialdehyde (MDA) level and induction of oxidative stress with significant decrease (P<0.05) in reduced glutathione (GSH), Glutathione S-transferase (GST), Superoxide dismutase (SOD), Catalase (CAT) levels. Histological study of the liver shows loss of normal architecture, small-sized cytoplasmic vacuole, cellular degeneration and necrosis. However, concomitant administration of aqueous extract of Telfairia occidentalis with cadmium chloride attenuated the induced hepatic injury, lipid peroxidation, and oxidative stress. In conclusion, aqueous extract of Telfairia occidentalis offer hepatoprotection by scavenging free radicals, reversing/inhibiting oxidative stress pathways and protecting the structural integrity of the liver.
