In a group of six patients diagnosed as having unilateral renovascular hypertension due to fibromuscular dysplasia, inulin glomerular filtration rate, (GFR) and PAH renal plasma flow, (RPF) clearances, urine flow (V), urine sodium (UVNa), potassium (UVK), urinary excretion of prostaglandin E2 (UVPGE2), thromboxane B2 (UVTxB2), and 6-keto prostaglandin F1 alpha (UVPGF1 alpha) were measured in ea...
The effect of torasemide and furosemide therapy was compared in 50 patients who had chronic heart failure and symptoms [NYHA class II-III] despite long-term therapy with both low-dose furosemide and angiotensin-converting enzyme inhibitors. In this randomized 6-month, open-label trial, baseline and follow-up echocardiograms and neurohumoral assays were obtained in 25 group F patients (continued...
Furosemide (Fu) chemical name is 5-(aminosulfonyl)-4chloro-2-[(2-furanyl methyl)amino)benzoic acid] (Figure 1) [1]. It has the following generic names: Frusemide, Fursemide, Aisemide, Beronald, Desdimin, Lasilix and others. The empirical formula is C12H11ClN2O5S corresponds to molecular weight of 330.77. Furosemide is a white to slightly yellow, odourless, almost tasteless crystalline powder, s...
Blood oxygen level-dependent (BOLD) MRI data of kidney, while indicative of tissue oxygenation level (Po2), is in fact influenced by multiple confounding factors, such as R2, perfusion, oxygen permeability, and hematocrit. We aim to explore the feasibility of extracting tissue Po2 from renal BOLD data. A method of two steps was proposed: first, a Monte Carlo simulation to estimate blood oxygen ...
Mechanoreceptors and chemoreceptors have been identified inside the kidney, but their functional role is still largely unclear. The aim of this study was to investigate whether changes in urine output could modify the discharge rate of renal afferent fibers. Experiments were performed in anesthetized cats in which afferent renal nerve activity (ARNA) was recorded by standard electrophysiologica...
Retention of iodine in the thyroid gland is the result of renal excretion and transport of iodine to thyroid cells. Both processes are affected by furosemide. The aim of our study was to test whether furosemide influenced radioiodine-131 ((131)I) retention in the thyroid gland of living mice. Our methods were as follows: After 15 days of low-iodine diet, 19 Swiss mice received an intra-peritone...
OBJECTIVES We compared therapeutic effects of furosemide, a short-acting loop diuretic, and azosemide, a long-acting one, in hypertensive heart failure rats to test the hypothesis that long-acting diuretics are superior to short-acting types in heart failure. METHODS Dahl salt-sensitive rats fed an 8% NaCl diet from age 8 weeks were divided at age 21 weeks (compensated hypertrophic stage) int...
In the title compound, [Na2(H2O)9](C7H4ClO2)(C12H10ClN2O5S) {systematic name: catena-poly[[[triaquasodium(I)]-di-μ-aqua-[triaquasodium(I)]-μ-aqua] 3-chlorobenzoate 4-chloro-2-[(furan-2-ylmethyl)amino]-5-sulfamoylbenzoate]}, both the original m-chloro-benzoic acid and furosemide exist with deprotonated carboxyl-ates, and the sodium cations and water mol-ecules exist in chains with stoichiometry ...
To examine the role of the macula densa in renin release, afferent arterioles alone or afferent arterioles with the macula densa attached were microdissected from rabbit kidney and incubated in Medium 199 for two consecutive 30-minute periods. Renin concentration in the medium was measured using partially purified rabbit angiotensinogen. Renin release rate over 1 hour from a single arteriole (o...
Objectives. The efficacy of high dose furosemide as a continuous infusion was compared with a bolus injection of equal dose in patients with severe heart failure. Background. The delivery rate of furosemide into the nephron has been proved to be a determinant of diuretic efficacy in healthy volunteers. Methods. In a randomized crossover study we compared the efficacy of a continuous infusion of...
