Anesthetized, nondiuretic rats and hamsters were infused with C14-labeled inulin-carboxylic acid or urea, and fluid was subsequently collected by micropuncture from surface tubules in the rats and from loops of Henle and collecting ducts in the hamst

After the intravenous administration of Il'1labeled L-diiodotyrosine (DIT), an increasing fraction of the labeled iodine of the serum becomes inorganic iodide as the DIT undergoes deiodination. Most of the labeled iodine which appears in the urine is

SummaryInulin and PAH concentrations and osmolalities were determined in samples of tubular fluid collected from surface convolutions of rat kidneys during urea diuresis. F/P inulin ratios averaged 1.6 for the proximal tubule, 2.9 for the distal conv

Anesthetized rats and hamsters were given Ca45 intravenously, and fluid was subsequently collected by micropuncture from glomeruli and surface tubules in the rats, and from loops of Henle in the hamsters. In nondiuretic animals, fluid:plasma calcium

Anesthetized rats were given urea-C14 intravenously and infused with 5% NaCl solution containing inulin-methoxy-H3. Fluid was collected by micropuncture from surface tubules for simultaneous determination of H3 and C14 activities and osmolality. Inul

The influence of Ca++ on the water permeability of proximal and distal tubules of the nondiuretic rat kidney has been studied, utilizing a micro-perfusion method. Addition of Ca++ to the perfused solution had no effect on the permeability of proximal

Intrarenal transport of urate-2-(14)C was studied in anesthetized rats using the microinjection technic. During saline diuresis, small volumes of urate-2-(14)C (0.24-0.48 mM) and inulin-(3)H were injected into surface proximal and distal convoluted t

Microperfusion experiments on the proximal convolution of the rat kidney in situ led to the following observations: 1. The concentration of Ca++ in tubular fluid at which the net flux of Ca++ is zero is about 2.66 mEq/L. This corresponds to a TF/P of

Fluid was collected by micropuncture from individual renal tubules of anesthetized rats and its pH determined with the quinhydrone microelectrode. The single glomerular sample and early proximal fluid were isohydric with arterial blood, but later pro
