The commonly used pesticides in agriculture cause enzyme inactivation and DNA damage via reacting with macromolecules and may also initiate peroxidation of poly-unsaturated fatty acids (PUFA) by generating of the reactive oxygen species (ROS), as a consequence they can lead to the oxidative stress. The objective of this study was to determine the oxidative and neurotoxic potential of sublethal chlorpyrifos in the brain tissue of Cyprinus carpio (C. carpio) for a period of 96 and 240 hours, respectively. Therefore, the levels of malondialdehyde (MDA), glutathione (GSH), advanced oxidation protein products (AOPP), protein carbonyl, and 8-hydroxydeoxyguanosine (8-OHdG) levels and activities of superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH-Px) and acetylcholinesterase (AChE...
