..., the glomerular filtration rate, estimated by the sodium thiosulphate clearance test, was within normal range, and the renal plasma flow was significantly lower than normal in the OSAS patients, thus the FF (filtration fraction) value was much higher than normal. FF before CPAP was not significantly correlated...

... : -0.8%) than in control subjects (DFR Na : -3.7%). Baseline values for glomerular filtration rate and renal plasma flow were reduced in congestive heart failure, but brain natriuretic peptide induced no significant changes between congestive heart failure and control subjects. Brain natriuretic peptide...

.... In cirrhotic rats with and without ascites, glomerular filtration rate tends to be higher ( P = 0.12), renal plasma flow is elevated ( P = 0.001) and nitration fraction is lower ( P = 0.002) than in healthy rats. 4. In conclusion, haemodynamic experiments in the cirrhotic rat should be performed in the awake...

...Jesper Melchior Hansen; Niels Vidiendal Olsen; Paul Peter Leyssac 1. The nephrotoxic effects of cyclosporin A may diminish the ability of the transplanted kidney to increase the glomerular filtration rate and effective renal plasma flow during infusion of dopamine or amino acids. 2. The present...

... to infusion of atrial natriuretic factor, the packed cell volume rose by 4.2% ( P < 0.001) and the filtration fraction by 5% (from 22 to 27%, P <0.05), but there was no significant change in renal plasma flow, glomerular filtration rate or mean arterial blood pressure. Likewise, the plasma catecholamine...

...Boothur J. Z. Danesh; Joyce Brunton; David J. Sumner 1. The effect of 4-6 weeks’ treatment with propranolol and nadolol on effective renal plasma flow (ERPF) and glomerular filtration rate (GFR) was studied, in 14 patients with essential hypertension, in single blind, random and cross-over design...

...A. Iaina; I. Nakash; E. Reisin; B. Spivack; H. E. Eliahou 1. Renin secretion rates in normal rats were determined with two different methods: (a) the product of renal plasma flow as measured by sodium p -aminohippurate and the difference between renal and peripheral vein renin activity; (b...

... glomerular filtration rate was unchanged, whereas effective renal plasma flow increased, so that filtration fraction decreased significantly. A similar increase in urinary sodium occurred whether subjects received a low or high sodium diet. Indices which related to the distal delivery of filtrate (fractional...
