RESUMO
The present work has been designed to investigate the hepatoprotective and renoprotective efficiency of alcoholic extract of Allium porrum and Bauhinia variegata leaves in thioacetamide-induced toxicity in adult Wistar rats. Allium porrum leaf extract, Bauhinia variegata leaf extract and their combinations were orally administered for 14 days then TAA (300 mg/kg) i.p. was injected once and the rats were sacrificed 2 days later. Plasma AST, ALT, GGT, total bilirubin, creatinine, urea, uric acid, triglyceride, cholesterol, HDL and LDL were measured. Liver MDA, GSH, CAT, SOD and TNF-α were evaluated. Histological examination was performed. The rats treated with TAA showed a significant increase in AST, ALT, GGT, total bilirubin, creatinine, urea, uric acid, total, triglyceride, cholesterol and HDL while it led to a significant decrease in protein and HDL. The treatment of rats with TAA resulted in a significant decrease of the hepatic GSH, SOD and CAT and a significant elevation of MDA and TNF-α. Allium porrum and Bauhinia variegata extracts alleviated the toxic effects of TAA on the liver and the kidney. In conclusion, treatment with Allium porrum and Bauhinia variegata extracts and their combination reduced deleterious effects of TAA on liver through antioxidant and anti-inflammatory properties.
