Evaluation of iohexol clearance to estimate glomerular filtration rate in normal horses
… under certain conditions. Estimation of the glomerular filtration rate (GFR), accepted as one of the earliest and most sensitive assessments of renal function, can be determined in horses using standard techniques such as endogenous or exogenous renal creatinine clearance. These techniques …

Evaluation of Iohexol Clearance to Estimate Glomerular Filtration Rate in Normal Horse Foals
Estimation of the glomerular filtration rate (GFR), accepted as one of the earliest and most sensitive indicators of renal dysfunction, can be determined in horses using standard techniques In adult horses and foals, renal dysfunction can occur as a secondary complication to gastrointestinal …

Changes of Glomerular Filtration Rate of Donated and Remnant Kidneys in A Week after Living Donor Kidney Transplantation
PURPOSE: In living donor kidney transplantation, the initial function of donor's kidneys will be split into the function of the donor's remnant kidney and the recipient's implanted kidney. The question whether the function of these remnant and implanted kidneys will change after donation and …

Changes of parathyroid hormone and vitamin D metabolites according to glomerular filtration rate in chronic kidney disease patients
BACKGROUNDS: Disturbances of mineral metabolism are common during the course of chronic kidney disease (CKD) and lead to serious and debilitating complications unless these abnormalities are addressed and treated. While secondary hyperparathyroidism develops during the early stages of chronic …

Influence of Pregnancy on Renal Function and Feturs in Women with Underlying Renal Disease
… through February 2006 who had been diagnosed glomerular disease by renal biopsy or were suspected as having glomerulonephritis. We analyzed changes in serum creatinine, random urine protein / creatinine, blood pressure, fetal status, and the pregnancy outcome each at the preconception state, …

Severe acute renal failure at Groote Schuur Hospital
… to days of renal dysfunction with a reduction in glomerular filtration rate (GFR) resulting in a failure to excrete nitrogenous waste products.

The Pharmacokinetics of Oxytetracycline in Dogs With Normal and Impaired Renal Function
… dysfunction, defined by the percentage of normal glomerular filtration rate (GFR), was estimated by ('125)I-iothalamate total body clearance. The pharmacokinetics of oxytetracycline (OTC) were compared before and after the induction of renal failure in three experiments: single intravenous dose …

Investigation of novel biomarkers associated with renal disease
… measures of renal function and damage (estimated glomerular filtration rate and urinary albumin to creatinine ratio). Retinal biomarkers have previously been associated with the most significant causes of chronic kidney disease (CKD), hypertension and diabetes, and the most important effect of …

Renal tubular secretion in chronic kidney disease: description, determinants, and outcomes
… chronic kidney disease are currently assessed by glomerular filtration rate and urinary albumin excretion. Other kidney functions, such as proximal tubular secretion, are not typically quantified. Tubular secretion is capable of clearing metabolites from the blood more efficiently than filtration, …

Association of variants in APOL1, MYH9 and HMOX1 WITH micro-Albuminuria among Sickle Cell disease patients from Cameroon
… in MYH9 and APOL1, and between estimated Glomerular Filtration Rate (eGFR) and End Stage Kidney Disease (ESKD) with HMOX1 variants among adult African Americans affected by SCD. However, the association between these variants and micro-albuminuria, a primary indicator of renal dysfunction, …

Clinico-pathological features of repeat renal biopsies in patients with lupus nephritis at Groote Schuur Hospital, Cape Town
… indication for the repeat biopsy (36.1%). The glomerular filtration rate and proteinuria worsened between the two biopsies (p=0.001 and 0.019) respectively suggesting disease progression. Most patients (65.4%) with a non-proliferative class of LN at first biopsy progressed into a proliferative …

The Effect of Nephrotomy on Renal Function and Morphology in Normal Cats
… Population: Ten adult female cats. Methods: Glomerular filtration rate (GFR), as determined by quantitative renal scintigraphy using 99mTc-DTPA, urinalysis, urine culture, and sonographic measurement of renal size were performed pre-operatively. A left or right nephrotomy (five randomly …

Acidosis and bone disease in chronic renal failure
… generally had a substantial reduction in glomerular filtration rate, a urine acidifying defect, and a number had clinically apparent osteomalacia. However, the association of the osteomalacia with the chronic metabolic acidosis seemed at least as strong as with the degree of uraemia, …

Development of a simple HPLC-UV method for determination of GFR by serum iohexol clearance
The glomerular filtration rate (GFR) is considered the best indicator of kidney function. Iohexol, a contrast agent, is currently considered to be a reference marker since it meets all the requirements of an ideal GFR marker. The aim of this study was to develop and validate a method for iohexol …

Retrospective comparison of cyclophosphamide and mycophenolate mofetil in lupus nephritis at Groote Schuur Hospital nephrology unit
… there were significant differences in estimated glomerular filtration rate (eGFR) and presence of glomerular crescents between both groups (p ≤ 0.05). After completion of induction therapy, there was no significant difference in remission status (76.0% versus 87.5%; p = 0.33) or relapse status …

Effect of Fenoldopam on Renal Function in Normal Dogs Following Nephrotomy
… groups: fenoldopam (F) or placebo (P). Baseline glomerular filtration rate (GFR), blood urea nitrogen (BUN), serum creatinine (SCr), urinalysis (UA), and urine culture were performed prior to surgery. A left bisection nephrotomy was performed via a standard midline celiotomy. Dogs in Group F …

Low molecular mass proteins as markers for renal function and dialysis efficiency
… treatment can be avoided. To measure the glomerular filtration rate (GFR) an invasive technigue is used. In this thesis an equation to estimate GFR (eGFR) by drawing a blood sample and measure the concentration of cystatin C is presented. This equation is the first one working both for …

Aspects of retransfusion of shed blood in cardiac surgery
… has been suggested as a more sensitive marker of glomerular filtration rate (GFR) than creatinine, which today is the most commonly used marker of GFR. In study I and II, we studied the distribution and the kinetics of lipid microemboli during cardiac surgery in a porcine model. The organ that …

Single nephron structure and function, and renal effects of catecholamines in the dogfish, Scyliorhinus canicula
… muscle sphincters, intra-arterial cushions and glomerular bypass shunts in renal vasculature was found. The function of these structures is discussed in relation to patterns of renal blood flow, blood pressure and glomerular perfusion. 6. Plasma levels of the catecholamines adrenaline, …
