Zinc nanoparticles mitigate azoxystrobin and its nanoencapsulation-induced hepatic and renal toxicity in rats

Abstract

This study sought to ascertain if zinc nanoparticles (ZnNPs) could lessen the toxicity of azoxystrobin (AZ). This naturally occurring methoxyacrylate is one of the most often used fungicides in agriculture in male albino rats. Six sets of 60 mature male albino rats were randomly assigned: control (distilled water), Azoxystrobin formulation (AZOF), Azoxystrobin nano-formula (AZON), ZnNPs, AZOF + ZnNPs, and AZON + ZnNPs. Blood and tissues were obtained for further immunohistochemical, pathological, and biochemical examination. The results showed that exposure to AZOF and AZON significantly increased the levels of the oxidative stress indicators glutathione peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD), and malondialdehyde (MDA). Additionally, AZOF significantly impacts liver function bioindicators, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. AZOF and AZON induced damage to the liver and kidney by disrupting vascular dilatation and causing hemorrhages, apoptosis, inflammatory lymphocytes, and necrosis. Furthermore, co-administration of ZnNPs with fungicides (AZOF and AZON) can gently enhance the alterations of oxidative stress and liver function bioindicators levels. These findings showed that ZnNPs could help male rats receiving AZ treat their histologically abnormal liver and kidney.
