Abstract

Introduction

The objective of this study was to investigate the effects of 3',4'-dihydroxyflavonol (DiOHF) on oxidative and antioxidant systems in kidney tissue and on renal function as distant organ damage following brain ischemia-reperfusion.

Methods

This study was conducted on 28 male Wistar-Albino rats, which were divided into four groups: Control, Sham, Ischemia-Reperfusion (I/R), and Ischemia-Reperfusion + DiOHF. Kidney tissue samples were collected to analyze malondialdehyde (MDA) and glutathione (GSH) levels. Additionally, concentrations of electrolytes (Ca, Cl, Na, K, and P), as well as urea, uric acid, creatinine, and urinary microprotein levels, were measured.

Results

Brain ischemia-reperfusion led to increased malondialdehyde (MDA) levels in both the kidney medulla and cortex, indicating oxidative stress in these distant organs, while glutathione (GSH) levels were suppressed. Additionally, ischemia-reperfusion caused elevations in blood and urine concentrations of urea, uric acid, creatinine, and urinary microproteins.

Discussion

This experimental model significantly elevated urea, uric acid, and creatinine levels, key indicators of kidney function, and similarly increased urinary microprotein loss. While our study demonstrates the detrimental effects of focal brain ischemia-reperfusion on kidney function as a distant organ, further research is needed to investigate its impact on other organs to gain a more comprehensive understanding of distant organ damage.

Conclusion

Results from this experimental model indicate that cerebral ischemia-reperfusion in rats suppresses the antioxidant system and increases oxidative stress in kidney tissue, leading to impaired renal function. However, a 1-week DiOHF treatment mitigated this damage by enhancing the antioxidant defense system.
