Validation of "transit renography" for the determination of the intrarenal distribution of plasma flow: comparison with the microsphere method in the anaesthetized rabbit and pig.
1. The spectrum of transit times of sodium o-iodohippurate (Hippuran) through the kidney can be derived from an 131I- (or 123I-) labelled Hippuran renogram by deconvolution. In the rabbit and pig, as has previously been shown in man, the frequency distribution curve for the transit times was bimodal. Since the transit time is likely to be proportional to the nephron length, the area of the firs...
متن کاملThe measurement of intrarenal flow distribution in man.
1. A new method, based on the transit time of omicron-iodohippurate sodium (Hippuran) through the kidney, is proposed as an accurate non-invasive means of measuring the intrarenal flow distribution in man. 2. Data from [123I]Hippuran gamma-camera renography are utilized in this method which employs region of interest selection, deconvolution, cross-correlation and curve subtraction to obtain th...

15 صفحه اولRegulation of renal blood flow by plasma chloride.
Micropuncture studies have shown that glomerular filtration rate (GFR) falls in response to a rise in Na(+) or Cl(-) concentrations in the loop of Henle, whereas studies in isolated kidneys have shown that GFR falls in response to osmotic diuresis. To define the separate effects of an acute increase in plasma sodium (P(Na)), chloride (P(Cl)) or osmolality (P(osmol)), changes in renal blood flow...
