Osmotic water permeability of Necturus gallbladder epithelium
An electrophysiological technique that is sensitive to small changes in cell water content and has good temporal resolution was used to determine the hydraulic permeability (Lp) of Necturus gallbladder epithelium. The epithelial cells were loaded with the impermeant cation tetramethylammonium (TMA+) by transient exposure to the pore-forming ionophore nystatin in the presence of bathing solution...
متن کاملOsmotic water permeability of human red cells
The osmotic water permeability of human red cells has been reexamined with a stopped-flow device and a new perturbation technique. Small osmotic gradients are used to minimize the systematic error caused by nonlinearities in the relationship between cell volume and light scattering. Corrections are then made for residual systematic error. Our results show that the hydraulic conductivity, Lp, is...
متن کاملEarly osmotic history of the plasma membrane.
The following topics, amonig others, aire conisidered: Pfeffer 's hypothesis of an invisible plasma membrane, to account for similarities in the osmotic behavior of plant cells and artificial osmometers; early doubts as to the reality of Pfeffer's membrane; denial by colloid chemists of the existence of plasma membranes because of the supposed failure of cells to obey osmotic laws; demonstratio...
متن کاملThe Protoplast: Plasma Membrane, Nucleus, and Cytoplasmic Organelles
Cells represent the smallest structural and functional units of life (Sitte, 1992). Living organisms consist of single cells or of complexes of cells. Cells vary greatly in size, form, structure, and function. Some are measured in micrometers, others in millimeters, and still others in centimeters (fi bers in certain plants). Some cells perform a number of functions; others are specialized in t...
متن کاملGlucocorticoids increase osmotic water permeability (Pf) of neonatal rabbit renal brush border membrane vesicles.
During postnatal maturation, there is an increase in renal brush border membrane vesicle (BBMV) osmotic water permeability and a parallel increase in aquaporin-1 (AQP1) protein abundance. The mechanisms responsible for these changes remain unknown. Because serum glucocorticoid levels rise postnatally and have previously been linked to other maturational changes in renal function, we examined th...
