INVOLVEMENT OF MAIN OXIDATIVE STRESS MECHANISMS IN THE TOXICITY OF BENOMYL AND CARBENDAZIM IN RATS
SUMMARY This study aimed to evaluate the role of oxidative stress in toxicity induced by BNL (benomyl) and its metabolite CBZ (carbendazim), which are systemic broad-spectrum benzimidazole fungicides. The activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GSH-Rd), γ−glutamyl transpeptidase (GGT) and glutathione-S-transferase (GST) as well as the levels of malonyldialdehyde (MDA), being a lipid peroxidation marker and reduced glutathione (GSH) were measured in the liver, kidney, testis and brain tissues of the rats, after acute exposure of the two fungicides and their mixture. In all tissues, it was observed that MDA levels were increased and changes in antioxidant defense system were occurred. The induction of oxidative stress manifested as changes in the activity and/or levels of antioxidative parameters has been suggested as the mechanism by which BNL and CBZ induces their toxic effects. OZET Bu calismada, genis spektrumlu sistemik benzimidazol grubu fungusidlerden olan BNL (benomyl) ve metaboliti CBZ (carbendazim)’ nin toksik etki mekanizmalarinda oksidatif stresin rolu arastirildi.
