introduction: renal ischemia reperfusion is considered to be one of the causes of acute renal failure (aki). in addition, renal ischemia is an important incident usually occurs due to renal transplantion, repair of suprarenal aneurysm, hemorrhagic shock. a recent study reported that reactive oxygen species (ros) are important mediators of aki. it seems essential to use antioxidant to decrease t...
introduction: during kidney and other organ's transplantation, the organ to be transplanted, must inevitably remain out of the body with little or no blood perfusion at all, for long period of time (ischemia). this causes the release of oxygen free radicals (ofr). reperfusion (reintroduction of blood flow) will further exacerbate the initial damage caused by the ischemic insult and may result i...
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...
objective(s):acute kidney injury (aki), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients. renal ischemia-reperfusion, one of the main causes of aki, is of particular importance in the setting of kidney transplantation. materials and methods: sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...
Renal ischemia–reperfusion (IR) is inevitable in partial nephrectomy and kidney transplantation. Acute tubular necrosis (ATN) induced by renal IR causes the loss of functional units kidney, pathologically presenting as nonhomogeneous distribution normal uriniferous tubules usually used to characterize activity. Optical coherence tomography (OCT) has been proven have ability image microstructure...
Objective(s): The aim of this study was to evaluate the effects of ground black seeds on renal tubular cell apoptosis following ischemia/reperfusion (I/R) injury in rats. Materials and Methods: Forty male Wistar rats were randomly allocated into 5 equal groups including Sham, I/R model and three I/R+ black seeds (5, 10 and 20%)-treated groups. I/R groups’ kidneys were subjected to 60 min of isc...
Background: Several studies indicate that gender differences exist in tolerance of the kidney to ischemia reperfusion (IR) injury. Recently, postconditioning (POC), induction of brief repetitive periods of IR, has been introduced to reduce the extent of the damage to the kidney. This method was shown to attenuate renal IR injury by modifying oxidative stress and reducing lipid peroxidation. Con...
Time course of renal ischemia/reperfusion and distance organ; lung dysfunction in male female rats
sIntroduction: Acute kidney injury (AKI) induced by ischemia-reperfusion (I / R) of the kidney as an inflammatory process in which multiple inflammatory factors are involved. Recently, one of the modalities of inflammation in AKI is Remote Ischemic Per-Conditioning (RIPerC). Materials and Methods: In this study, bilateral renal artery and vein occlusion were done for 45 minute and reperfusion a...
Background: Renal injuries associated with ischemia/reperfusion are a prevalent clinical phenomenon that can cause the emergence of progressive kidney diseases, eventually leading to chronic kidney injuries. The present study was conducted to evaluate the results obtained from non-invasive imaging using small-animal SPECT and investigate the recovery process in an animal model of renal ischemia...
