RESUMO
Acetamiprid (ACP) is a neonicotinoid insecticide that is the most effective pesticide for crop protection as well as flea control in agricultural animals and pets in the world. The goal of this study was to look at the in vivo effects of a sublethal dose of ACP on hematotoxicity, oxidative stress, hepatotoxicity, nephrotoxicity, immunotoxicity, and histological alterations, as well as the role of quercetin (QE) in alleviating these effects. Twenty adult male mice were divided into four equal groups orally administered corn oil (control), QE (50 mg kg-1 b.wt.), ACP (1/10 LD50) or ACP plus QE for two weeks. The results showed that ACP significantly lowered the body weight gain, hematological indices, glutathione (GSH), and both cellular and humoral immunity, On the other hand, levels of lipid peroxidation (LPO), glutathione peroxidase (GPx), and liver and kidney marker values were considerably increased in male mice exposed to ACP. In addition, examination under light microscopic showed that ACP induces histological alterations in liver and kidney tissues. The results also revealed that treating intoxicated mice with QE significantly reduced the deleterious effects of ACP. In conclusion, current results show that ACP at the sub lethal dose poses toxic risks to the liver and kidneys, and QE as a natural material enhances antioxidant defenses, which can be used as a potential interventional therapy against negative effects of pesticides like ACP.
