RESUMO
Scientific evidence has shown that fipronil induces oxidative stress and genotoxicity. Our study aimed to evaluate the potential oxidation in redox parameters and DNA, as well as determine the protective effect of date extract of increasing resistance to cellular damage. 30 Male albino rats were divided into six groups ( n = 5): 1) control group; 2) treatment group with date extract (1 g/kg B.W.); 3) treatment group with 1/20 LD50 of fipronil; 4) treatment group with 1/40 LD50 of fipronil; 5) treatment group with 1/20 LD50 of fipronil + 1 g/kg date extract; and 6) treatment group with 1/40 LD50 of fipronil + 1 g/kg dates extract. Date extract showed a high content of phenolic compounds and antioxidant properties. Fipronil increased 8-hydroxy-2-deoxyguanosine levels and lipid peroxidation by malondialdehyde but decreased the total antioxidant capacity in plasma. Moreover, glutathione, catalase, and superoxide dismutase levels in the liver and kidney decreased, along with histopathological abnormalities. Additionally, tail moment parameters of liver DNA and micronucleus frequencies in the bone marrow increased. This study showed that fipronil-induced various health hazards in vivo, whereas date extract alleviated the said toxicological effects. However, date extract failed to reduce genotoxicity.
