Background: Previous studies have shown increases in endothelin (ET) concentration of plasma and renal tissues in acute renal failure (ARF). ET has a potent vasoconstrictor effect, through binding with its ETA receptors, and may play some roles in renal hemodynamic dysfunction in ARF.Objective: To examine the beneficial effect of a selective ETA-receptor antagonist on renal dysfunction and tis...
Objective- to assess the normal ultrasonographic findings of kidney in the Raiini goat. Design- Experimental study. Animals- 10 female Raiini goats. Procedures- .Necropsy was carried out and Kidneys were measured in length, width, and diameter after fixation in formalin. Ultrasonography was carried out by longitudinal and transversal planes to evaluate all renal structures. Echogenicity and ...
the correlation of vesicoureteral reflux (vur), urinary tract infection (uti) and renal scarring is well known. several risk factors for renal parenchymal lesions have been reported previously. we determine the incidence of renal parenchymal damage and outcome in the siblings of children with primary vur. a total of 96 siblings of patients with vur, were evaluated with direct voiding cystograph...
Acute Pyelonephritis (APN) is one of the most common bacterial infections seen in children that may lead to renal scarring. Vesicoureteral reflux (VUR) is an important risk factor of renal damage but not the only one. Materials and Methods: In order to determine the association between dimercaptosuccinic acid (DMSA) scintigraphic and voiding cystourethrographic findings, a retrospective study w...
Aims: Renal vascular clamping during partial nephrectomy can lead to renal ischemia and kidney damage due to reperfusion injuries, but a surgical technique without any ischemia can eliminate such unwanted effects on kidney function. The present study aimed to demonstrate the feasibility of partial nephrectomy in conditions where the renal artery is ready to be clamped. Patient Information: In ...
background renal scintigraphy with technetium 99m labeled dimercaptosuccinic acid (99mtc-dmsa) is a traditional imaging technique commonly used to detect renal scar in patients with probable vesicoureteral reflux (vur) and/or urinary tract infection (utis). we determined whether normal results of dmsa renal scan obviate the need for voiding cystourethrography (vcug) in evaluating children with ...
and it is an important factor that leading to cardiac ischemiareperfusion injury. In the past, most attention was focused on cardiac cells. While in recent years, myocardiac microvascular endothelial cells (MMECs) attracted scholar’s attention. The one hand, endothelial cells participate in many important body balance regulation, and can synthesize and secrete a variety of biologically active s...
Early reperfusion of the ischemic myocardium has been shown to reduce mortality in acute myocardial infarction. Unfortunately, reperfusion, although necessary to relieve ischemia, may be followed by morphological, functional, and electrical changes that result in additional myocardial damage, known as reperfusion injury. In animal models, several pharmacologic agents and reperfusion strategies ...
