Abstract
The surface membrane properties of LLC-PK1, cells grown,vith and witho ut various amounts of gentamicin or tobramycin for various lengths of time were determined by measuring the diffusion coefficient of N-(7-ni trobenz-2-oxa-1,3-diazol 4-yl)dipalmitoyl-L-alpha-phosphatidylethanola mine (NBD-PE) and the percentage of NBD-PE free to diffuse after photo bleaching. 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 pr eexposure levels and the diffusion coefficient decreased.
