Does water drag solutes through kidney proximal tubule?

Pflügers Archiv, 1983
Coupling of salt and water movements across kidney proximal tubules was studied in the presence of an induced transepithelial osmotic water flux. Convoluted proximal tubules from rabbit kidney were perfused in vitro with a control solution, with or without 50 mM/l of mannitol or raffinose in the both.

SEM of the proximal tubule of the adult rabbit kidney

The Anatomical Record, 1978
AbstractThe present study utilizes the scanning electron microscope (SEM) to reveal the surface morphology of proximal tubular cells and the parietal cells of Bowman's capsule of the adult rabbit nephron. To facilitate the examination of the basal surface of these cells, proximal tubules were dissected free and treated with collagenase to remove the ...

Pressure and flow in proximal tubules of rat kidneys

Experientia, 1962
An proximalen Harnkanalchen wurde die Stromungsgeschwindigkeit der Flussigkeit bestimmt. Es wurde die Durchgangszeit eines Oltropfens durch einzelne Kanalchen gemessen. Der Druckabfall im Kanalchen wurde aus Durchgangszeit und Dimension des Kanalchens berechnet.

Glucose transport in isolated perfused proximal tubules of snake kidney

American Journal of Physiology-Legacy Content, 1976
Glucose transport was studied in isolated, perfused snake (Thamnophis spp.) renal tubules. When 14C-labeled and unlabeled glucose concentrations for bath and perfusate were identical, net transepithelial glucose transport occurred from lumen to bath. Maximum rates of transport were 1.24 X 10-12 and 2.17 X 10-12 mol min-1 mm-1 in proximal-proximal and ...

Transepithelial potential difference in the proximal tubule of Necturus kidney

Pfl�gers Archiv European Journal of Physiology, 1976
Transepithelial potential difference (p.d.) was measured in the proximal tubule of Necturus kidney in vivo, by means of microelectrodes filled either with a 3M KClion or with a Ringer's solution for amphibians. The average transepithelial p.d., measured with KCl-tips, was: -1.4 +/- 2.4 mV (early convolutions), -0.1 +/- 2.0 mV (middle convolutions) and +

Kidney proximal tubule cells: Epithelial cells without EGTA-extractable annexins?

Biochemistry and Cell Biology, 2000
The expression and the subcellular localizations of annexins I, II, IV, VI, and XIII in renal epithelial cells were investigated, using immunological techniques with specific monoclonal antibodies. Upon performing Western blotting experiments, no annexins VI and XIII were detected in kidney, whereas annexins I, II, and IV were.

Role of Proximal Tubules in the Pathogenesis of Kidney Disease

2011
The proximal tubules make up a significant portion of the kidneys; proximal tubule epithelial cells are the most populous cell type in the kidney, and carry out diverse regulatory and endocrine functions where numerous transporters are located. Under normal circumstances, more than two thirds of filtered salt and water, and all filtered bicarbonate is ...

Oxidative Stress in the Kidney: Proximal Tubule Disorders

2010
Redox changes initiate various cellular signals in the cells, and the redox environment can determine if a cell will proliferate, differentiate, or die. Imbalance of the redox status such as during oxidative stress can trigger a series of events, leading to cellular dysfunction.

Response of primary rabbit kidney proximal tubule cells to estrogens

Journal of Cellular Physiology, 1999
The effects of estrogens on the growth and function of primary rabbit kidney proximal tubule (RPT) cells have been examined in hormonally defined phenol red-free medium. 17beta-estradiol was observed to stimulate growth at dosages as low as 10(-10) M.

Short-circuit current measurements in proximal tubule of Necturus kidney

American Journal of Physiology-Legacy Content, 1961
A modified short-circuit method, which requires only one pair of electrodes, was applied to the proximal tubule of the Necturus kidney for determination of the short-circuit current as a measure of active ion transport across the tubular wall. The indifferent electrode was placed on the surface of the exposed kidney and the tubular lumen was punctured
