Retracted: Oxidative stress induced by aluminum oxide nanomaterials after acute oral treatment in Wistar rats

Abstract

This study investigated the oxidative stress induced after acute oral treatment with 500, 1000 and 2000 mg kg⁻¹ doses of Al₂O₃ -30 and -40 nm and bulk Al₂O₃ in Wistar rats. Both the nanomaterials induced significant oxidative stress in a dose-dependent manner in comparison to the bulk. There was no significant difference between the two nanomaterials. However, the effect decreased with increase with time after treatment. The histopathological examination showed lesions only in liver with Al₂O₃ nanomaterials at 2000 mg kg⁻¹.
