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 کاملSome reflections on the mechanism of renal tubular potassium transport.
Analysis of the driving forces acting on the movement of potassium across individual membranes of tubule cells shows that both active and passive components play an important role in the regulation of potassium transport. Distal and cortical collecting tubule and papillary collecting duct elements are the key nephron sites participating in a complex fashion to translate a wide variety of metabo...
متن کاملEffects of Nitric Oxide on Renal Proximal Tubular Na+ Transport
Nitric oxide (NO) has a wide variety of physiological functions in the kidney. Besides the regulatory effects in intrarenal haemodynamics and glomerular microcirculation, in vivo studies reported the diuretic and natriuretic effects of NO. However, opposite results showing the stimulatory effect of NO on Na+ reabsorption in the proximal tubule led to an intense debate on its physiological roles...
متن کاملInhibition of Renal Tubular Transport of Methotrexate by 1
therefore,to establishmethodsby whichconsistentlyhigh and stable levels of MTX could be maintained in plasma in the clinical setting. A major factor militating against achievement of these ends is the rapid excretion of MTX determined in man as well as in experimental animals. We undertook this experimental study to develop a systematic approach to the maintenance of high plasma levels of MTX b...
