INTRODUCTION Acute renal dysfunction is a common complication of cardiac surgery. Furosemide is used in prevention, or treatment, of acute renal dysfunction. This study was conducted to evaluate the protective effects of intra- and early postoperative furosemide infusion on preventing acute renal dysfunction in elective adult cardiac surgery. METHODS Eighty-one patients, candidates of electiv...

The obese Zucker rat is a valuable model for studying kidney disease associated with obesity and diabetes. Previous studies have shown that substitution of animal protein with soy ameliorates the progression of renal disease. To explore the participation of nitric oxide (NO) and caveolin-1 in this protective effect, we evaluated proteinuria, creatinine clearance, renal structural lesions, nitri...

Studies were carried out to determine the intrarenal adenosine production during hypoxia, and the protective effects of a selective adenosine A(1) receptor antagonist 8-(noradamantan-3-yl)-1, 3-dipropylxanthine (KW-3902) on hypoxia-induced renal hemodynamic changes. We used an in vivo microdialysis method and measured the renal interstitial concentration of adenosine in response to hypoxic expo...

OBJECTIVES This study aimed to develop drugs from natural sources to overcome the side effects of many of synthetic drugs. Methanol extracts of both pericarp and seeds of Pleiogynium solandri were used to investigate antioxidant, hepatoprotective, and renal function protective, analgesic, and anti-inflammatory effects and to determine the chemical composition of the extract responsible for bioa...

Sirtuin 1 (Sirt1) is a NAD+-dependent deacetylase that exerts many of the pleiotropic effects of oxidative metabolism. Due to local hypoxia and hypertonicity, the renal medulla is subject to extreme oxidative stress. Here, we set out to investigate the role of Sirt1 in the kidney. Our initial analysis indicated that it was abundantly expressed in mouse renal medullary interstitial cells in vivo...

Vascular endothelial cells may serve crucial roles in the development of acute kidney injury (AKI). microRNA (miR)‑21, which possesses a renal protective function has been found on vascular endothelial cells. The present study aimed to test the hypothesis that miR‑21 may protect vascular endothelial cells against injury, which may contribute to the protective effects of renal delayed ischemic p...

Objective(s): Gentamicin is used for the treatment of Gram-negative bacterial infections. However, gentamicin administration is limited because of nephrotoxicity. The aim of the present study was to evaluate the protective effect of crocin against gentamicin-induced nephrotoxicity in rats. Materials and Methods: Thirty two male Wistar rats received gentamicin (100 mg/kg, IP), with or without c...

background: the aim of this study was to investigate the protective effects of crocin against tissue damages and leukocyte infiltration induced by renal ischemia/reperfusion. methods: in this experimental study, 35 male wister rats weighing 250-300 g were randomly divided into 5 groups; 1. operated controls, but no vessel occlusion was considered and passed during equivalent reperfusion period ...

OBJECTIVE Prolonged warm ischemia time and increased intra-abdominal pressure caused by pneumoperitoneum during a laparoscopic donor nephrectomy could enhance renal ischemia reperfusion injury. For this reason, laparoscopic donor nephrectomy may be associated with a slower graft function recovery. However, an adequate protective response may balance the ischemia reperfusion damage. This study i...

BACKGROUND The effect of paricalcitol on renal ischemia-reperfusion injury (IRI) has not been investigated. We examined whether paricalcitol is effective in preventing inflammation in a mouse model of IRI, and evaluated the cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) pathways as a protective mechanism of paricalcitol. METHODS Paricalcitol (0.3 μg/kg) was administered to male C57BL/6 ...
