Riboflavin transport by isolated perfused rabbit renal proximal tubules.
Rabbit renal proximal tubular transport of riboflavin (RF) was examined by using the in vitro isolated tubule perfusion technique. We found that proximal tubules actively reabsorbed (J(lb)) and secreted (J(bl)) RF. At 0.1 microM RF concentration, J(bl) was significantly higher than J(lb), resulting in a net secretion. This net secretion of RF was decreased at 0.01 microM RF concentration and in...
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 کاملPotential mechanisms involved in the absorptive transport of cadmium in isolated perfused rabbit renal proximal tubules.
UNLABELLED Lumen-to-cell transport, cellular accumulation, and toxicity of cadmium as ionic cadmium (Cd(2+)) or as the L-cysteine (Cys) or D,L-homocysteine (Hcy) S-conjugate of cadmium (Cys-S-Cd-S-Cys, Hcy-S-Cd-S-Hcy) were studied in isolated, perfused rabbit proximal tubular segments. When Cd(2+) (0.73 microM) or Cys-S-Cd-S-Cys (0.73 microM) was perfused through the lumen of S(2) segments of t...
متن کاملIntracellular calibration of a pH-sensitive dye in isolated, perfused salamander proximal tubules
We evaluated the dye 4',5'-dimethyl-5-(and -6-) carboxyfluorescein (Me2CF) for determining the intracellular pH(pHi) of isolated, perfused proximal tubules of the salamander. The intracellular absorbance spectrum, corrected for the intrinsic absorbance of the tubule, was obtained once per second. The dye was incorporated into tubule cells by exposing them to the membrane-permeable precursor 4',...
متن کاملFurosemide effect on isolated perfused tubules.
BURG, MI., L. STONER, J. CARDINAL, AND N. GREEN. Furosemide effect on isolated perfused tubules. Am. J. Physiol. 225(l): 119-124. 1973 .-Proximal convoluted tubules, thick ascending limbs of Henle’s loop, and cortical collecting tubules were dissected from rabbit kidneys, and perfused in vitro. The effect of the diuretic agent furosemide on electrolyte transport and electrical potential differe...
