Influence of aqueous diffusion layer on passive drug diffusion from aqueous cyclodextrin solutions through biological membranes.
Most drugs permeate biological membranes via passive diffusion and it is generally assumed that the main barrier is the lipophilic structure of the membrane. However, we have observed that the unstirred water layer adjacent to the membrane surface can in some cases be a barrier just as effective as the lipophilic membrane itself. Hydrophilic cyclodextrins can enhance drug delivery through biolo...

15 صفحه اولThe interaction of long chain sodium carboxylates and sodium dodecylsulfate with lead(II) ions in aqueous solutions.
The interaction of sodium octanoate, decanoate or dodecanoate with lead(II) has been studied in aqueous solutions using potentiometry, electrical conductivity, turbidity and ICP-OES measurements. These show an alkyl chain length dependence on the behavior. At the lead(II) concentration used (1.0 mM), relatively strong interactions are observed with the decanoate and dodecanaote, leading to form...

متن کاملDiffusion coefficients in viscous sodium alginate solutions
Department of Applied Physics, University of Fukui, Bunkyo 3-9-1, Fukui, 910-8507 Japan Abstract Sodium alginate solution, being viscous hydrocolloid, was examined voltammetrically in the context of viscous effects by use of a ferrocenyl compound as a redox probe. Voltammograms were almost independent of concentrations of sodium alginate even in a solid-like state. Diffusion coefficients of the...
