Pesticides, such as organophosphorus and pyrethroids, are extensively used in the agrofields which can significantly increase crop productivity. Humans are exposed to pesticides via dermal contact, inhalation and ingestion due to occupational exposure. The objective of the present study was to evaluate the protective role of the aqueous extract of Crataegus oxyacantha during acute exposure of rats to the combination of deltamethrin (DM) and chlorpyrifos (CPF) in rats (DCF). The combination of vitamins C and E (Vit CE) was used as a standard antioxidant. The Crataegus oxyacantha extract revealed the presence of a high level of phenolic compounds identified by HPLC analysis. Male wistar rats were divided into six groups: (I) corn oil, (II) AECO (1 ml/100 g), (III) DCF (DM 5 mg/kg, CPF 1 mg/kg), (IV) AECO + DCF, (V) Vit CE (Vit C 100 mg/kg, Vit E 100 mg/kg), and (VI) Vit CE + DCF. AECO and Vit CE were administered 10 days before the administration of DCF. The findings revealed that the administration of DM and CPF mixtureinduced a significant decrease in serum AChE and DNA damage, as indicated by brain DNA fragmentation. In addition, behavioral tests by open field and elevated plus maze showed impaired recognition memory. The results showed that AECO or Vit CE alleviated significantly neurobehavioral alterations, reduced lipid peroxidation in brain, and restored the antioxidant parameters (SOD, CAT, GPx and GSH) to normal levels. Furthermore, brain DNA fragmentation and histopathology in DCF treated rats were improved by AECO administration. All results revealed that C. oxyacantha extract, rich in polyphenoliccompounds, had potential antioxidant effects on the combination of DM and CPF-induced oxidative brain damage.
