Popis: The surface membrane properties of LLC-PK1 cells grown with and without various amounts of gentamicin or tobramycin for various lengths of time were determined by measuring the diffusion coefficient of N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)dipalmitoyl-L- alpha-phosphatidylethanolamine (NBD-PE) and the percentage of NBD-PE free to diffuse after photobleaching. One hour of exposure to tobramycin decreased the percentage that was free to diffuse. After 1 day or longer of exposure to either aminoglycoside the percentage that was free to diffuse returned to preexposure levels and the diffusion coefficient decreased.
