Renal Proximal Tubule Cells
Previous data suggested an active Clconductance in the renal proximal convoluted tubule, although single channel conductance and regulation were not found. We have investigated the presence and regulation of the C1channel in proximal convoluted tubules by patch clamp analysis. The current-voltage relationship of whole cells with 130 mM NaCI in the pipette was nonlinear. The addition of 1-34 PTH...
متن کاملFine Structure of Lipid Granules in Proximal Tubule Cells of Mouse Kidney
In electron microscopic investigations on the proximal tubule of the mouse kidney, large osmiophilic granules in the cytoplasm of the epithelial cells have been found by various authors (2, 13, 14, 20). Rhodin (13) and Clark (2) have pointed out that the granules contain concentric lamellae, but there have been no further investigations on the fine structure of these granules so far. Recently M...
متن کاملFine Structure of Mouse Renal Glomerulus
Present concepts of glomerular structure stem from the classical paper of Bowman (7) who described in 184:~ the vascular pattern of the kidney and the connection between the glomerulus and the renal tubule. Details of the large literature dealing with the structure of the renal glomerulus up to the year 1930 can be found in the reports of McGregor (27) and von Mbllendorff (32). Outstanding is t...
متن کاملSome Electrical Properties of Single Renal Tubule Cells
At a considerable rate of metabolic expenditure, the renal tubules transfer large amounts of ions across their epithelial cell layer. Recently, a better characterization of the nature of individual ionic transport processes at the single nephron level has become possible through an assessment of some electrical characteristics of tubule cells. The response of either transmembrane or transepithe...
متن کاملRenal Proximal Tubule
In the subsequent 20-min interval after intra-aortic injection of these test solutions, capillary protein concentration remained at (isoncotic infusions) or returned to (colloid-free and hyperoncotic fluids) control values. Whereas reabsorption after colloid-free solutions returned to base line levels in parallel with the return in capillary protein concentration, after colloid infusions (which...
