The ameliorative effect of cerium oxide nanoparticles on chlorpyrifos induced hepatotoxicity in a rat model: Biochemical, molecular and immunohistochemical study.

Background: Chlorpyrifos (CPF) is a widely used insecticide that causes toxicity to living organisms through the production of free radicals. Cerium oxide nanoparticles (CeONPs) are a new antioxidant agent that has proved therapeutic effects. We evaluated the effect of CeONPs on CPF hepatotoxicity.
