Abstract:
Objective: To evaluate the ameliorative effect of melatonin on sub-chronic chlorpyrifos (CPF) and cypermethrin (CYP)-evoked cognitive changes in male Wistar rats. Methods: Fifty adult male Wistar rats, divided into five groups of ten rats each, were used for the study. Groups 1 and Ⅱwere given distilled water and soya oil (2 mL/kg) respectively. Group Ⅲ was administered with melatonin at 0.5 mg/kg only. Group Ⅳ was administered with CPF [7.96 mg/kg (1/10th LDResults: CPF and CYP induced cognitive deficits and increased brain malonaldehyde concentration, which were all ameliorated by melatonin. Conclusion: Cognitive deficits elicited by CPF and CYP was mitigated by melatonin due to its antioxidant property.
