Última Correlation between sodium and potassium excretion in 24- and 12-h urine samples BJMBR Mill,J.G.; Silva,A.B.T. da; Baldo,M.P.; Molina,M.C.B.; Rodrigues,S.L.. Low-sodium and high-potassium diets have been recommended as an adjunct to prevention and treatment of hypertension. Analysis of these nutrients in 24-h urine has been considered the reference method to estimate daily intake of these minerals. However, 24-h urine collection is difficult in epidemiological studies, since urine must be collected and stored in job environments. Therefore, strategies for shorter durations of urine collection at home have been proposed. We have previously reported that collecting urine during a 12-h period (overnight) is more feasible and that creatinine clearance correlated strongly with that detected in 24-h samples. In the present study, we collected urine for 24 h divided into two 12-h periods (from 7:00 am to 7:00 pm and...

Aldosterone concentrations vary in advanced chronic renal failure (CRF). The isozyme 11β-hydroxysteroid dehydrogenase 2 (11β-HSD2), which confers aldosterone specificity for mineralocorticoid receptors in distal tubules and collecting ducts, has been reported to be decreased or normal in patients with renal diseases. Our objective was to determine the role of aldosterone and 11β-HSD2 renal microsome activity, normalized for glomerular filtration rate (GFR), in maintaining K+ homeostasis in 5/6 nephrectomized rats. Male Wistar rats weighing 180-220 g at the beginning of the study were used. Rats with experimental CRF obtained by 5/6 nephrectomy (N = 9) and sham rats (N = 10) were maintained for 4 months. Systolic blood pressure and plasma creatinine (Pcr)... Tipo: Info:eu-repo/semantics/article Palavras-chave: Aldosterone; 5/6 Nephrectomy; 11β-HSD2; Potassium excretion.
