	abstract = {<p>The present study was designed to evaluate the probable ameliorative role of quercetin (QCN) against oxidative hepatotoxicity induced by aluminum oxide nanoparticles (AlONPs) with a diameter \&lt; 30~nm and lead acetate (Pb) co-exposure in adult male Sprague-Dawley rats. Rats were weighed and allocated to seven groups (n = 10 each) and were treated orally via orogastric gavage for 60 successive days: rats of the 1st group were kept as control given distilled water (1~ml/kg), rats of the 2nd group received 2~ml/kg BW/day corn oil; rats of the 3rd group were administered 20~mg/kg BW QCN/day; rats of the 4th group received 100~mg/kg BW AlONPs; rats of the 5th group received 50~mg/kg BW Pb; rats of the 6th group co-received AlONPs and Pb at the same previous doses; and rats of the 7th group were co-administered AlONPs, Pb, and QCN at the same previous doses. At the end of the experiment, serum levels of alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total, direct, indirect bilirubin, triglycerides, total cholesterol, HDL, VLDL, and LDL were estimated. The hepatic oxidative stress biomarkers as superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GPx), were also evaluated. Finally, the histopathological and histomorphometric evaluations and the residues of Al and Pb in hepatic tissues were assessed. AlONPs and/or Pb exposure significantly elevated lipid peroxidation levels and considerably altered the hepatic biochemical parameters; nevertheless, QCN significantly reduced hepatic enzymes compared to toxicant exposed groups. Additionally, QCN significantly improved AlONPs-afforded liver tissue damage, as established in microscopic findings on the liver in the group treated with AlONPs + Pb. Conclusively, QCN could be a candidate natural agent to safeguard the liver versus the co-harmful impacts of AlONPs and Pb toxicity.</p>
