The purpose of this study was to evaluate the protective effect of ethanolic olive fruit extract (OFE) and its phenolic compound, oleuropein (OLE), against hepato-renal toxicity induced by deltamethrin (DEM), a synthetic pyrethroid, in Wistar rats. The kidney and liver tissues were collected after 30 days of treatment for subsequent investigation. Rats that were given DEM had a highly significant elevation in the serum biomarkers as well as hepatic and renal levels of lipid peroxidation (MDA). Additionally, a significant reduction in the total antioxidant capacity (ABTS+), superoxide dismutase (SOD) and catalase (CAT) activities was noted. This toxic effect was confirmed by histological studies and the expression levels of inflammatory (cox-2) and apoptotic genes (bcl-2 and p53). The findings for the OFE and OLEtreated groups highlighted the efficacy of olive fruit phenolic compounds as hepatic and renal-protectant in DEM-induced hepato-renal toxicity through improving the oxidative status as well as suppressing inflammation and apoptosis. Therefore, they may be used as protective natural compounds against DEM-induced hepato-renal toxicity.
