Prior intake of Brazil nuts attenuates renal injury induced by ischemia and reperfusion

J. bras. nefrol; 40 (1), 2018
ABSTRACT Introduction: Ischemia-reperfusion (IR) injury results from inflammation and oxidative stress, among other factors. Because of its anti-inflammatory and antioxidant properties, the Brazil nut (BN) might attenuate IR renal injury. Objective: The aim of the present study was to investigate wheth...

Tadalafil protector effect during ischemia-reperfusion in rats

Acta cir. bras; 32 (11), 2017
Abstract Purpose: To evaluate histological parameters in rat renal tissue after tadalafil use during hot ischemia for 45 minutes and reperfusion for 24 hours. Methods: Twenty rats were divided into 2 groups. In the experimental group 10 mg/kg of tadalafil was used per gavage before the procedure. All...

The effects of local ischemic preconditioning and topical hypothermia in renal ischemia/reperfusion injury in rats

Acta cir. bras; 32 (10), 2017
Abstract Purpose: Topical hypothermia and local ischemic preconditioning have been shown to reduce renal ischemia-reperfusion (I/R) injury individually. We examined whether combination of both strategies lessens renal I/R injury. Methods: Post right nephrectomy, 40 male Wistar rats were randomly assi...

Perconditioning combined with postconditioning on kidney ischemia and reperfusion

Acta cir. bras; 32 (8), 2017
Abstract Purpose: To evaluate if combination of perconditioning and postconditioning provides improved renal protection compared to perconditioning alone in a model of renal reperfusion injury. Methods: Thirty rats were assigned into 6 groups: normality; sham; ischemia and reperfusion; postconditionin...

Laparoscopic donor nephrectomy in unusual venous anatomy - donor and recepient implications

Int. braz. j. urol; 43 (4), 2017
ABSTRACT Objectives Laparoscopic donor nephrectomy is now a commonly performed procedure in most of renal transplantation centers. However, the suitability of laparoscopy for donors with abnormal venous anatomy is still a subject of debate. Materials and methods Between August 2007 and August 2014, 2...

Low-energy shock wave preconditioning reduces renal ischemic reperfusion injury caused by renal artery occlusion

Acta cir. bras; 32 (7), 2017
Abstract Purpose: To evaluate whether low energy shock wave preconditioning could reduce renal ischemic reperfusion injury caused by renal artery occlusion. Methods: The right kidneys of 64 male Sprague Dawley rats were removed to establish an isolated kidney model. The rats were then divided into fou...

The relationship between renal warm ischemia time and glomerular loss. An experimental study in a pig model

Acta cir. bras; 32 (5), 2017
Abstract Purpose: To investigate the glomerular number after different warm ischemia times. Methods: Thirty two pigs were assigned into four groups. Three groups (G10, G20, and G30) were treated with 10, 20, and 30 minutes of left renal warm ischemia. The sham group underwent the same surgery without r...

Relación entre gravedad de arteriosclerosis y progresión de enfermedad renal en pacientes nefrectomizados
Relation between severity of atherosclerosis and progression of renal disease in nephrectomized patients

Medicina (B.Aires); 77 (2), 2017
Nefrectomía radical se asocia a disminución progresiva de función renal. Los parámetros en insuficiencia renal post-nefrectomía están identificados, no así la importancia de la histopatología vascular en la pieza de nefrectomía. Nuestro objetivo fue evaluar si la gravedad de la aterosclerosis en...

Cyclosporine A attenuates apoptosis and necrosis after ischemia-reperfusion-induced renal injury in transiently hyperglycemic rats

Acta cir. bras; 32 (3), 2017
Abstract Purpose: To investigate the effects of cyclosporine A on renal ischemia-reperfusion injury during transient hyperglycemia in rats. Methods: In a model of ischemia-reperfusion-induced renal injury and transiently induced hyperglycemia by intraperitoneal injection of glucose, 2.5 g.kg-1, Wistar...

Influence of remote ischemic conditioning and tramadol hydrochloride on oxidative stress in kidney ischemia/reperfusion injury in rats

Acta cir. bras; 32 (3), 2017
Abstract Purpose: To evaluate the effects of tramadol hydrochloride associated to remote ischemic perconditioning on oxidative stress. Methods: Twenty five male rats (Wistar) underwent right nephrectomy and were distributed into five groups: Sham group (S); Ischemia/Reperfusion group (I/R) with 30 minu...
