Some aspects of flow and diffusion in the proximal tubule of the kidney

Journal of Theoretical Biology, 1965
Abstract A general theory of flow and diffusion in the proximal tubule of the kidney is outlined. Both radial and axial effects are discussed. An approximate analysis based on the equations of flow and diffusion indicates that radial diffusion in the tubule is not a limiting step in the transport of the osmotically active salts.

Chloride distribution in the proximal convoluted tubule ofNecturus kidney

The Journal of Membrane Biology, 1981
To assess the mechanism(s) by which intraluminal chloride concentration is raised above equilibrium values, intracellular Cl- activity (alpha iCl) was studied in the proximal tubule of Necturus kidney. Paired measurements of cell membrane PD (VBL) and Cl-selective electrode PD (VBLCl) were performed in single tubules, during reversible shifts of ...

Micropuncture study of proximal tubule pH in avian kidney

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1987
Transepithelial potentials (PD) and pH gradients were measured by in vivo micropuncture in superficial proximal tubules of anesthetized European starlings. The average PD for 46 tubules was 2.24 +/- 1.17 mV (mean +/- SD), lumen negative. Only a single lumen-positive potential was recorded, even though late proximal segments are accessible to ...

Effects of various cephalosporins on the proximal tubule of the human kidney

European Journal of Clinical Pharmacology, 1978
Cephamandol 6.0 g, cephazolin 6.0 g or cephacetrile or cephalothin 8.0 g were administered as short-term infusions on 3 consecutive days to informed volunteers, who had no history or evidence of impairment of renal function. There were 15 subjects in the cephamandol, cephacetrile and cephalothin groups and 14 subjects in the cephazolin group.

Protein degradation in kidney proximal tubule cell monolayers

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1994
Isolated proximal tubule cells have been labelled with L-[4,5-3H]leucine prior to cell division. Histochemical staining demonstrated the purity of the cultures. The bicarbonate ion or a collagen support was required for cell growth. Different culture growth rates were established by varying these parameters.

Evidence for a bicarbonate leak in the proximal tubule of the rat kidney

Pfl�gers Archiv European Journal of Physiology, 1980
To elucidate the mechanism responsible for the establishment of steady state pH at zero net flux (pH infinity) in proximal convoluted tubules, luminal pH was recorded continuously with antimony microelectrodes under three experimental conditions. First: luminal pH in stationary droplets was allowed to reach pH infinity (6.76 +/- 0.07) and then carbonic
