    Aim: Sepsis is a clinical pathology, characterized by a severe and exaggerated inflammatory response. One of the most frequently damaged organs in sepsis is the kidney. Quercetin has anti-inflammatory, anti-proliferative, and antioxidant effects. In this study. it was aimed to examine the protective effects of quercetin on the kidneys. Material and Methods: In the scope of this study, 31 rats were planned to be used in the experiments. The groups and number of animals were as follows: Group 1:1.5 ml saline, Group 2: 1.5 ml olive oil, Group 3: intestinal ligation and puncture procedure was used to create experimental sepsis method. Group 4:20 mg/kg quercetin was administrated by gavage. Group 5: quercetin was administered in intragastrically at doses of 20 mg/kg. In biochemical analyzes of kidney tissue samples, BUN, creatinine, MDA and GSH values were checked. Cell damage, inflammation and fibrosis were evaluated histopathologically. Results: As a result of this study, tissue GSH levels were significantly different between groups 3 and 4 (p- 0.001). In terms of BUN value, it was found to be significantly higher in group 3 (p= 0.002). In tissue histology, glomerulitis (p, 0.001), tubular cell necrosis (p= 0.001) and mesenchymal matrix increase (p= 0.001) were different between groups 3 and 4. Finally, no fibrosis was observed in any group (p> 0.05). Discussion: Quercetin has protective effects on kidney tissue against organ damage caused by sepsis.
