Postsecretory reabsorption of urate in man
Arthritis & Rheumatism, 1975These results are consistent with a model for renal tubular transport of urate in which there is reabsorption of both filtered and secreted urate. Urate secretion greatly exceeds total urate excretion, and most secreted urate is reabsorbed. At least a portion of urate reabsorption occurs at a site distal to or coextensive with the urate secretory site.

The Assessment of Renal Calcium Reabsorption
1984Renal clearances studies rest upon comparisons of concentrations in the plasma (P; mass/vol) with simultaneously measured urinary excretion rates (UV; mass/time). Their value depends on adequacy of the assumption, that the function that relates excretion rate to plasma concentration, contains a minimum of variables and, that those variables are ...

Aspects of Tubular Reabsorption Revisited
Chest, 1970Current concepts as to how reabsorption of filtered fluid occurs in the kidney are discussed. Emphasis is placed on certain unique problems arising from the remarkable covariance of amounts of filtered and reabsorbed. A concept advanced by Carl Ludwig over 100 years ago is exhumed and found to provide a reasonable basis for glomerulotubular balance ...

Loop diuretics reduce lithium reabsorption without affecting bicarbonate and phosphate reabsorption
Acta Physiologica Scandinavica, 1990The effects of the loop diuretics ethacrynic acid and bumetanide on lithium, bicarbonate and phosphate reabsorption were compared in 16 anaesthetized, normovolaemic dogs. In six dogs, ethacrynic acid (3 mg kg‐1body wt) significantly reduced absolute lithium reabsorption from 29.3 ± 4.1 to 19.0 ± 3.4μmol min‐1, fractional lithium reabsorption from 0.65 ±

Creatinine reabsorption by the aged kidney
International Urology and Nephrology, 2008The handling of renal creatinine in human beings has classically been described as the result of two particular physiological processes: glomerular filtration and proximal tubular secretion. However, there are particular physiological situations in which tubular creatinine reabsorption has been documented, such as in the case of healthy newborns and ...

Tubular Reabsorption and Secretion
2012This chapter begins with comparing the filtered load of materials with the amount excreted and shows that in some cases all of the filtered load is reabsorbed, and in others it is added to by secretion. It introduces renal titration and considers the titration of inulin, glucose, phosphate, and PAH.

Further remarks on the correction for reabsorption
Journal of Luminescence, 1984The formula for correction for reabsorption in the case of a plane-parallel luminophor excited and observed from one side is presented in a form convenient for computation. This form clearly shows the effect on the reabsorption correction of changing the parameters of the experiment.
