Introduction: Renal ischemia/reperfusion (I/R) injury due to reactive oxygen species (ROS) formation is the main cause of acute kidney damage. Nitric oxide (NO) biosynthesis and oxidative stress are closely related to the pathogenesis of renal I/R injury. This study was undertaken to determine the effects of L-arginine (L-arg) as NO donor and aerobic exercise (EX) and also the combination of L-...

Background & Target: Ischemia Reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. In this study, the effect of pentoxyfylline on bcl2 gene expression changes and cell injury in kidney of rat following Ischemia Reperfusion were evaluated.Methods: In this experimental study, 20 male wistar rats with average weight of...

Renal ischemia reperfusion injury triggers complement activation, but whether and how the small proinflammatory fragments C3a and C5a contribute to the pathogenesis of this injury remains to be elucidated. Using C3aR-, C5aR-, or C3aR/C5aR-deficient mice and models of renal ischemia-reperfusion injury, we found that deficiency of either or both of these receptors protected mice from injury, but ...

background: simvastatin is a widely used medication in cardiac care. here we evaluate the role of atp sensitive potassium (katp) channels in simvastatin induced renal protection after renal ischemia/reperfusion (i/r) injury.    methods: a total of 81 male wistar rats, were treated with simvastatin (10 and 20mg/kg/day gavage, one week). some groups received glibenclamide (katp channel inhibitor ...

Objectives: Ischemia/reperfusion (I/R) injury is commonly seen in cardiovascular surgery, activates inflammation and causes renal damage. In this experimental study, we aimed to assess the effects of different doses (5 30 mg/kg) methylprednisolone (MP), which has anti-inflammatory effect, on ischemia/reperfusion injury. Methods: Thirty-two male Wistar albino rats were randomly divided into four...

Objectives: Curcumin has anti-inflammatory and antioxidative properties. The objective of this study was to investigate the therapeutic effects of curcumin on functional disturbances, oxidative stress, and leukocyte infiltration induced by renal ischemia/reperfusion (I/R). Materials and Methods: Animals were randomly divided into 9 groups. The groups with 24-h reperfusion consisted of sham-24h,...

conclusions our study demonstrates that preconditioning of kidney with chronic ptu administration protects renal tissue against iri and this phenomenon was mediated through no system. the results suggest a potential indication for using ptu to protect the kidney before transplantations and to reduce the risk of tissue rejection afterwards. background renal ischemia/reperfusion injury (iri) is a...

Ischemia followed by reperfusion is a major cause for renal injury in both native kidney and renal allografts. Hyperhomocysteinemia, a condition of elevated plasma homocysteine (Hcy) level, is associated with cardiovascular diseases. Recent evidence suggests that Hcy, at higher levels, may be harmful to other organs such as the kidney. In this study, we investigated the role of Hcy in ischemia-...

BACKGROUND Acute kidney injury is a common clinical comorbidity and early diagnosis is crucial for improving prognosis, but there is still no ideal biomarker for early diagnosis. MATERIAL AND METHODS miRNA microarray was used for detecting miRNA in kidney subjected to renal ischemia-reperfusion injury 12 h after reperfusion. Real-time PCR was performed to validate the results of microarray. m...
