Lipid Peroxidation and Dna Damage in Different Stages of Acute Renal Failure

چکیده
Introduction: Oxidative stress is an imbalance between the formation of Reactive oxygen species and protective antioxidant defense. It is known that oxidative stress increases the Acute renal failure. Measurement of oxidative stress parameters may be a simple tool for monitoring the progression of acute renal failure. Aim: The aim of this study was to evaluate oxidative stress in acute renal failure patients by Lipid peroxidation product Malondialdehyde (MDA), Total antioxidant capacity (TAC) and oxidative DNA damage product and compare its level among the patients of varying severity as per RIFLE classification. Materials and methods. We conducted a cross sectional study to compare oxidative stress parameters. Blood samples were collected from 62 patients with ARF, admitted to the Vinayaka Mission’s Medical College & Hospital, Salem from March 2009 to July 2010. We further subdivided the patients according to RIFLE classification. Results: The levels of MDA, Index of oxidative status MDA/TAC and DNA damage product 8 OH deoxy guanosine were significantly higher among failure group when compared to risk and injury. Total antioxidant capacity and super oxide dismutase (SOD) were found to be decreased.

The Protective Effect of Antioxidant and Anti-inflammatory Nanoparticles in Renal Ischemia-Reperfusion Damage
Background& objectives: Renal ischemia-reperfusion (IR) damage occurs during renal transplantation in end-stage renal disease (ESRD) patients which activate immune responses. Inflammatory responses by increased levels of cytokines can lead to acute kidney injury (AKI) that contributes to the loss of renal grafts and graft dysfunction. The purpose of this study was to review the therapeutic effe...
متن کاملOxidative and nitrosative stress in acute renal ischemia.
Generation of reactive oxygen species and nitric oxide in hypoxia-reperfusion injury may form a cytotoxic metabolite, peroxynitrite, which is capable of causing lipid peroxidation and DNA damage. This study was designed to examine the contribution of oxidative and nitrosative stress to the renal damage in ischemic acute renal failure (iARF). iARF was initiated in rats by 45-min renal artery cla...
