Development of renal potassium excretion capacity in the neonatal rat.
We investigated the capacity of newborn rats to excrete an acute potassium load to understand the development of a renal potassium excretion system. Three groups of the rats (7-14 d) were used to collect urine periodically over 6 h after oral infusion of potassium: control (no potassium loading) and low- and high-potassium-loaded rats. In the low-potassium-loaded group, infused with about 0.6 m...
متن کاملMicropuncture Study of Renal Potassium Excretion in the Rat.
MALNIC, GERHARD, RUTH M. KLOSE, AND GERHARD GIEBISCH. Micropuncture study of renal potassium excretion in the rat: Am. J. Physiol. 206(4): 674-686. I g64.-Samples of proximal and distal tubular fluid were collected from rats maintained on a control, a low-K, or a high-K, low-Na diet. All animals received inulin-C 14. Plasma (P) and tubular fluid (TF) were analyzed for Na and K by dual-channel m...
متن کاملRecent advances in the field of renal potassium excretion: what can we learn from potassium channels?
Potassium channels in the apical and basolateral membranes of tubule cells serve several important functions. They contribute to the generation of the cell-negative potential, mediate volume reductions following cell swelling and play a key role in secretion of potassium in both the thick ascending limb of Henle's loop and principal tubule cells of the initial and cortical collecting tubules. S...

tate (DOCA) and cortisol. Potassium excretion per nephron increased strikingly within 18 hr of contralateral nephrectomy and by 7 days, excretion rates were 600% of control values for the remnant kidney., More potassium was excreted in the first 5 hr after administration of a test dose of potassium by the remnant kidney alone in the postnephrectomy state than by both the remnant and intact kidn...
متن کاملEvidence suggesting renal tubular excretion of potassium in man during recovery from acute renal insufficiency.
In 1942 Winkler and Smith (1), studying the simultaneous renal clearances of exogenous creatinine and potassium in dogs following the injection of potassium salts, concluded that potassium is normally filtered at the glomerulus and subjected to a variable degree of tubular reabsorption. The highest potassium/creatinine clearance ratio obtained by these authors was 0.40. In 1948 Berliner and Ken...
