Measurement of effective renal plasma flow in congestive heart failure
European Journal of Nuclear Medicine, 1981In the management of patients with congestive heart failure (CHF), it is often desirable to have precise knowledge of overall renal function, including the effective renal plasma flow (ERPF). It has long been recognized that ERPF is diminished in CHF.

Estimating the effective renal plasma flow from the hippurate renogram
Nuclear Medicine Communications, 1985A method for estimating the effective renal plasma flow (ERPF) from renograms is presented. Renograms obtained in 91 patients were used to test the method. The clearance values derived from renography were compared with those obtained with infusion clearance. It was shown that the ERPF was able to be estimated from the renogram with a standard error of

Conjugation of p-Aminohippurate by the Kidney and Effective Renal Plasma-flow
Nature, 1961THE clearance of p-aminohippurate has become the standard method for the determination of effective renal plasma-flow, with the assumption that there is no conjugation of p-aminohippurate during its passage through the kidney from the blood to the urine.

[Effective renal plasma flow in renal transplant rejection].
Gaoxiong yi xue ke xue za zhi = The Kaohsiung journal of medical sciences, 1993It is important to differentiate between cell-mediated (acute) and humoral (chronic) rejection in renal transplantation in order to initiate appropriate therapy. Since effective renal plasma flow (ERPF) provides a sensitive method of analyzing renal function, this test was undertaken to evaluate the possibility of differentiating acute and chronic ...

A simplified method for the determination of effective renal plasma flow
Clinica Chimica Acta, 1967Abstract In order to find a simplified but reliable method for the determination of the effective renal plasma flow, several methods, employing p-aminohippurate (PAH) as well as p-acetylaminohippurate (PACAH), were investigated. It was found that the use of PAH is inappropriate for any method in which examination of the urine is omitted, since there ...

Effect of furegrelate on renal plasma flow after angiotensin II infusion
Canadian Journal of Physiology and Pharmacology, 1990We had previously shown that selective thromboxane synthetase inhibition with furegrelate increases urinary excretion of 6-ketoPGF1α, the hydrolysis product of prostacyclin after stimulation of renal prostaglandin synthesis with furosemide. The present study assessed the functional significance of this "redirection" of prostaglandin formation using a ...

Relationship of Creatinine Clearance to Orthoiodohippurate Measured Effective Renal Plasma Flow
American Journal of Kidney Diseases, 1983Effective renal plasma flow (ERPF) was measured utilizing 1-131 orthoiodohippurate (OIH). The OIH ERPF was correlated in 50 patients with routine 24-hour urine creatinine clearance measurements and with a formula predicting creatinine clearance based on age, weight, and serum creatinine (formula creatinine clearance).

Simultaneous determination of glomerular filtration rate and effective renal plasma flow
Clinical Physics and Physiological Measurement, 1991A method is described for the simultaneous determination of GFR and ERPF within the normal range using a single injection of 51Cr-EDTA and 125I-OIH. Reference values of GFR (range 59-176 ml min-1) and ERPF (268-810 ml min-1) were calculated from bi-exponential analysis of curves based on multiple plasma samples.

Simplified estimation of glomerular filtration rate and effective renal plasma flow
European Journal of Nuclear Medicine, 1981A method is described for the determination of GFR and ERPF using a combined injection of 51Cr-EDTA and 125I-iodohippurate. Plasma samples obtained at 60 min and 150 min after administration were used to determine a flow rate F assuming a monoexponential clearance of the tracers.

Blood Purification, 2008
The effect of amino acid infusion on renal hemodynamics was examined in 13 healthy subjects. Seven subjects participated in the first experimental protocol: study 1 -amino acids were infused for 3 h to increase plasma amino acid levels 2- to 3-fold above baseline; study 2 – amino acids were infused with somatostatin and peripheral replacement of ...
