The permeation rate of salicylate across a dialysis membrane was studied in the presence of various types of carboxymethylcellulose. The presence of the polymer in the salicylate solution increased the permeation rate of salicylate. The data were ana

The reaction of stannous fluoride with hydroxyapatite at pH values less than 2 was studied. The X-ray diffraction powder pattern indicates that the major product is SnHPO 4. Chemical analysis corroborated this finding and also indicated a minor amoun

Passive drug transport across a membrane involves the resistances in series offered by the membrane and the liquid layer immediately adjacent to it. The liquid layers generally are referred to as unstirred aqueous diffusion layers, suggesting that so

A recently introduced drug dissolution rate model based on convective diffusion was evaluated by experimentally determining dissolution rates. Alkyl p-aminobenzoates were used as the test compounds in a dissolution cell which promoted laminar flow of

Solutions of stannous fluoride are reacted with hydroxyapatite and the progress of the reaction is monitored by calcium analysis. The formation of Sn3F3PO4 proceeds faster with an increase in SnF2 concentration and can be further increased by adding
