چکیده

Objectives: The present study aimed to investigate the antioxidant activity of cerium oxide nanoparticles (CeNPs) against paraquat (PQ)-induced liver injury in rats. Methods: Thirty-two male rats were divided into four ۸-member groups and treated intraperitoneally with PQ and/or CeNPs for ۱۴ days. Group ۱ received PQ (۵ mg/kg/d), group ۲ received CeNPs (۱۵, ۳۰, and ۶۰ mg/kg/d), group ۳ received a combination of PQ (۵ mg/kg/d) and CeNPs (۱۵, ۳۰, and ۶۰ mg/kg/d), and group ۴ (control group) received saline solution. Serum samples along with liver tissue samples were collected from all the rats. Oxidative stress (OS) biomarkers including total antioxidant capacity, lipid peroxidation, total thiol groups, DNA damage, and nitric oxide levels were determined. Histological samples were also analyzed using hematoxylin and eosin staining slides. Results: Levels of oxidative stress and hepatic tissue damage were significantly higher in the PQ group compared to the control group. CeNPs at a dose of ۱۵ mg/kg showed the antioxidant activity and compromised the PQ-induced damage. Conclusion: In the scenario tested in this study, CeNPs could reduce the levels of OS, as well as hepatic damage induced by PQ.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
