Protective Role of Quercetin on Thioacetamide-Induced Renal Injury in Adult Male Albino Rats

ABSTRACT

Background: Thioacetamide (TAA) is a recognized industrial poisonous agent drastically used in animal studies for induction of hepatic necrosis, fibrosis and cirrhosis. It is additionally reported to be nephrotoxic through induction of oxidative stress. Quercetin (QE) has a high antioxidant capacity via free radical scavenging, transition metal ion binding, and lipid peroxidation inhibition. Aim of the work The goal of this research was to see if QE may help reduce the negative effects of thioacetamide on renal tissue by histological examination of the kidney. Material and methods: Twenty four adult male Albino rats 7–9 weeks old around 180–200g body weight were allocated into 3 groups; Group I (n=8) receiving distilled water, Group II (n=8); rats receiving TAA and Group III (n=8); receiving TAA and QE. Results: Renal tissues were examined under a light microscope stained by Harris Hematoxylin & Eosin (H&E stain), Periodic acid Schiff (PAS) and Masson’s Trichrome for TAA-treated groups revealed severe histopathological changes, whereas specimens obtained from QE-treated groups showed only mild changes. Immunohistochemical results corroborated these findings. Conclusion: This study demonstrated the ameliorative consequences of QE in opposition to TAA-induced renal injury in rats. The result of this study might contribute in the development of a novel complementary alternative medication in combating and therapeutic intervention of TAA-induced renal injury.
