Objective: In furtherance of the scientific search for suitable antidotes for pro-oxidative toxicants which man is exposed to on daily basis, the study investigated the modulatory potential of Ficus exasperata leaf extract on arsenate-mediated hepatic and renal toxicity using rats as a model.
Methodology: Twenty-eight rats were sorted into four groups containing seven rats each. Group A (control) received distilled water while 10 mg/kg bw of sodium arsenate was administered intraperitoneally to groups B, C and D to induce hepatic and renal damage. Group C and D were treated with oral administration of 100 mg/kg bw and 200 mg/kg bw of methanolic leaf extract of Ficus exasperata respectively for 14 days.
Results: Arsenate significantly (P?0.05) induced hepatic and renal damage characterized by elevated levels of serum urea, creatinine, uric acid, alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Arsenate also caused decreased serum concentrations of albumin, globulin and total protein as well as significant depletion in antioxidant status (glutathione–S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) in the liver and kidney of the rats. Administration of leaf extract of Ficus exasperata significantly (P?0.05) attenuated all these toxic effects by boosting antioxidants status and normalizing serum hepatic and renal markers.
Conclusion: These results are indicative of the modulatory potential of Ficus exasperata leaf on liver and kidney dysfunction arising from oxidative damage.
