Comparative physiology of renal tubular transport mechanisms.
This manuscript discusses current concepts of glomerular filtration and tubular transport of sodium, water, potassium, and urinary acidification by vertebrate kidneys in a comparative context. Work in mammalian and amphibian nephrons receives major emphasis due to our interest in application of new techniques for investigation of cellular mechanisms; when available, data from other vertebrate c...
متن کاملRenal tubular transport of inorganic sulfate.
GLOBUS, DAVID L., E. LOVELL BECKER AND DAVID D. THOMPSON. Renal tubular tran.@ort of inorganic sulfate. Am. J. Rh ysiol. 200(5): 1105-1110. I g6 I .-The urinary excretion of radiosulfate by the dog was investigated after a rapid injection into one renal artery. Radiosulfate appeared in the urine before simultaneously injected creatinine. After the plasma sulfate concentration had been elevated,...

متن کاملEpoxyeicosatrienoic acids affect electrolyte transport in renal tubular epithelial cells: dependence on cyclooxygenase and cell polarity.
We investigated the effects of epoxyeicosatrienoic acids (EETs) on ion transport in the polarized renal distal tubular cell line, Madin-Darby canine kidney (MDCK) C7. Of the four EET regioisomers (5,6-EET, 8,9-EET, 11,12-EET, and 14,15-EET) studied, only apical, but not basolateral, application of 5,6-EET increased short-circuit current (I(sc)) with kinetics similar to those of arachidonic acid...
متن کاملRenal transport of neutral amino acids
Uptake of L-proline, hydroxy-L-proline and 5-oxo-L-proline by luminal-membrane vesicles isolated either from whole cortex or from pars convoluta or pars recta of proximal tubules was studied by a spectrophotometric method. Uptake of L-proline and hydroxy-L-proline by vesicles from whole cortex was mediated by both Na+dependent and Na+-independent, but electrogenic, processes, whereas transport ...
