BACKGROUND Patients with stage 5 chronic kidney disease (CKD) begin chronic hemodialysis with variable diuresis levels correlated to a comparable low glomerular filtration rate. Residual diuresis influences long-term evolution of the hemodialyzed patient, modifying the prognosis even if optimal Kt/ V is achieved. AIM OF THE STUDY The present study emphasizes the main determining factors of di...

In the present study, the pathophysiologic role of glomerular hemodynamic factors in the early phase of HgCl2-induced acute renal failure is evaluated in the dog. This model of moderate ARF is characterized by a parallel fall in glomerular filtration rate (delta GFR, -43%) and renal blood flow (delta RBF, -38%) within the first three hours after HgCl2 administration. Glomerular hemodynamics wer...

INTRODUCTION Recent studies show increased prevalence of Cognitive Dysfunction in patients with Chronic Kidney Disease. OBJECTIVE To evaluate this association in users enrolled in the Family Health Unit Ponte. METHODS We studied a sample of 246 elderly. We assessed cognitive function using the Mini Mental State Examination and the Glomerular Filtration Rate using the equation Modification o...

Previous studies have shown an association between the alpha-adducin Gly460Trp polymorphism and salt-sensitive hypertension. Not much is known about the effects of the variants of this polymorphism on renal hemodynamics and function. Therefore, we performed the present study to investigate the effect of the 460Trp allele of the alpha-adducin gene on renal hemodynamics in one hundred and sevente...

Background: Hypertension is one the most common causes of chronic kidney disease (CKD). One of the major concerns in hypertensive patients is early detection of renal disorders. In the past, serum creatinine (Scr) concentration was used as a marker of kidney function, but it proffers a late reflection of reduced glomerular filtration rate. Cystatin C and neutrophil gelatinase-associated lipocal...

Compared with wild-type mice, adult endothelial nitric oxide synthase (eNOS) knockout mice (eight months of age) have increased blood pressure (BP) (126±9 mmHg vs. 100±4 mmHg), and an increased renal vascular resistance (155±16 vs. 65±4 mmHg.min/ml). Renal vascular resistance responses to i.v. administration of noradrenaline were markedly enhanced in eNOS knockout mice. Glomerular filtration ra...

Introduction: The aim of this study was to determine the effects of linear and nonlinear periodized resistance training on serum levels of creatinine, glomerular filtration rate (GFR), and creatinine clearance in women with abdominal obesity.    Materials & Methods: This study was conducted on 42 women who were randomly assigned into linear periodized (LP) resistance training (N=15, age: 40.4...

cGMP generation has been associated with many of the vascular and endocrine actions of atrial natriuretic factor (ANF) in vitro. To examine the role of cGMP as a second messenger for the renal hemodynamic action of ANF in vivo, we measured glomerular filtration rate (GFR) and cGMP concentration in systemic artery, renal vein, and urine as well as in Bowman's space and end-proximal tubule (by fr...

Glomerular filtration rate and renal plasma flow increase by 40 to 65 and 50 to 85%, respectively, during normal pregnancy in women. Studies using the gravid rat as a model have greatly enhanced our understanding of mechanisms underlying these remarkable changes in the renal circulation during gestation. Hyperfiltration is largely due to increased renal plasma flow, the latter attributable to p...

Perlhaps nowlhere in the broad spectrum of present-day renal plhysiology studied with micropunctuire teclhniques lhas there occurred a greater nor more damaging erosion of confi(lence in the interpretation of results than in the area pertaining to the measurement of glomerular filtration rate (GFR) in single neplhrons. In large part, this decline in confidence can be traced to a recent series o...
