Paths of Transtubular Water Flow in Isolated Renal Collecting Tubules
The cells of perfused rabbit collecting tubules swell and the intercellular spaces widen during osmotic flow of water from lumen to bath induced by antidiuretic hormone (ADH). Ouabain had no influence on these changes. In the absence of net water flow intercellular width was unaffected when tubules were swollen in hypotonic external media. Therefore, during ADH-induced flow widening of intercel...
متن کاملPerfusion of isolated renal tubules.
The metlhodls usedl for perftusinig isolatedi renal tul)ules are generally clifferent from microptuncture, as are the prob)lems encounteredl. Altlhotuglh I will concentrate maiinly on the teclhnical aslpects of perfuision, it seems to me most important to evaluate to wlhat extent the restults are p)ertinent to the stt(ly of kidney function. Are the tubules still "alive?' Are they still fuinctio...
متن کاملby isolated rat renal tubules
1. The effect of glucocorticoids on the deiodination of thyroxine (T,) to 3,5,3’-trbiodothyronine (T,) was studied in rat renal tubules prepared by collagenase digestion. 2. In short-term (6 h) experiments, cortisol and dexamethasone inhibited the conversion of T, into T, at concentrations of 2 x lo-, moll1 and 2 x mol/l respectively. The inhibition by cortisol and dexamethasone was time depend...
متن کاملUltrastructural Studies of Vasopressin Effect on Isolated Perfused Renal Collecting Tubules of the Rabbit
Isolated cortical collecting tubules from rabbit kidney were studied during perfusion with solutions made either isotonic or hypotonic to the external bathing medium. Examination of living tubules revealed a reversible increase in thickness of the cellular layer, prominence of lateral cell membranes, and formation of intracellular vacuoles during periods of vasopressin-induced osmotic water tra...
متن کاملDivalent anion transport in isolated renal tubules.
Inorganic phosphate and sulfate are the major divalent anions in biological fluids at physiological pH. The isolated perfused renal tubule technique has been used to address a number of questions about their renal transport; the purpose of this review is to summarize this information. Initial studies addressed traditional questions about the direction and segmental localization of phosphate and...
