Acidification in the distal tubule of the Amphiuma kidney
Acta Physiologica Scandinavica, 1983The acidification of the urine within the distal tubule of Amphiuma means was studied with micropuncture techniques. Antimony microelectrodes calibrated in vivo were used for measuring the intratubular pH and samples were taken for the determination of Na+‐ and Cl‐‐concentrations and for determining buffer lines within the HCO‐3‐CO2 buffer system.

Increases of cell ATP produced by exogenous adenine nucleotides in isolated rabbit kidney tubules.
American Journal of Physiology, 1986The effects of exogenous nucleotides on adenine nucleotide metabolism and cell cation levels in normal and O2-deprived isolated rabbit kidney tubules were studied to gain insight into ways in which exogenous nucleotides could contribute to ameliorating ...

Characteristics of glutamine metabolism by rat kidney tubules: a carbon and nitrogen balance.
Canadian Journal of Biochemistry, 1979The metabolism of glutamine by a suspension of rat kidney tubules was studied in vitro. The influence of duration of incubation, glutamine concentration, and metabolic state of the donor animals was investigated.

Lipids in the Proximal Tubules of the Kidney in Diabetic Coma
The American Journal of Forensic Medicine and Pathology, 2000Vacuolization of the renal tubular epithelial cells (the Armanni-Ebstein lesion) associated with diabetic hyperglycemia is usually regarded as an accumulation of glycogen. In a case of death of diabetic coma, the vacuoles were stained strongly for lipids.

Regenerating Tubules for Kidney Repair
2010Stem/progenitor cells are in the focus of regenerative medicine for a future therapy of acute and chronic renal failure. However, broad knowledge about parenchymal regeneration in kidney is lacking. For that reason developmental pathways leading from stem/progenitor cells to newly formed tubules have to be investigated.

Cytosolic free calcium levels in rabbit proximal kidney tubules.
American Journal of Physiology, 1982Cytosolic free Ca levels were measured in isolated rabbit proximal kidney tubules using a previously described null-point method (19). Control values for cytosolic free Ca levels averaged 0.45 +/- 0.09 microM (n = 13).

A new species of Goussia (Apicomplexa, Coccidia) in the kidney tubules of the cod, Gadus morhua L.
, 1989. Segments of the kidney tubules of about 16% of cod caught in the approaches to Halifax Harbour were found to contain a coccidian parasite. Macrogametes developed in an epicellular position, and microgamonts, unsporulated and sporulating oocysts, and ...

Glucocorticoid stimulation of Na-K-ATPase in superfused distal segments of kidney tubules in vitro.
American Journal of Physiology, 1982The ability of glucocorticoids to regulate Na-K-ATPase activity directly was assessed in separated rat kidney tubules derived from the distal nephron.

Effects of 4-dimethylaminophenol in rat kidneys, isolated rat kidney tubules and hepatocytes.
Xenobiotica; the fate of foreign compounds in biological systems, 19801. Addition of 4-dimethylaminophenol (DMAP) to suspensions of isolated rat kidney tubules increased extracellular lactate dehydrogenase (LDH) at concn. which did not markedly affect gluconeogenesis. ATP content was also decreased by DMAP but this did not

Primary Kidney Proximal Tubule Cells
2004Primary rabbit kidney epithelial cell cultures can be obtained that express renal proximal tubule functions. Toward these ends, renal proximal tubules are purified from the rabbit kidney by the method of Brendel and Meezan. To summarize, each kidney is perfused with iron oxide, which becomes associated with glomeruli.
