Abstract: A psyllium composition in tablet form is provided having a wetting agent, a disintegrant and a binding agent. In one embodiment, the wetting agent is polysorbate 80, the binding agent is polyvinyl pyrrolidone and the dry binding agent and disintegrant is microcrystalline cellulose. Calcium carbonate may also be added to serve as a disintegrant in HCL. The tablets are manufactured by mixing the psyllium powder with a solution of povidone and polysorbate 80. Microcrystalline cellulose may be added either during or after granulation. After mixing, the composition is compressed into tablet form. The mixing of the ingredients in specific quantities allows a tablet to be manufactured that is both resistant to fracture and at the same time disintegrates easily and quickly in the gastrointestinal tract of the patient.

Abstract: An aqueous oral preparation is provided having from about 0.5% to about 10% by weight of a peroxide compound such as hydrogen peroxide or urea peroxide and from about 0.01% to about 2% by weight of a compound providing fluoride or fluoride-containing ions in an aqueous composition. The compound may further include a thickening agent, such as carboxy polymethylene, a non-ionic surfactant, such as Pluronic brand poloxamer, buffering agents, stabilizers, glycerine, sweeteners, and deionized filterd water as a solvent. A variety of flavoring and/or coloring agents may also be added. A stable compatable and highly effective dental preparation is thereby provided.

Abstract: Means for developing a plurality of chromatograms simultaneously without prior equilibration are disclosed. When the means of the invention are used, the chromatograms are vertically positioned with their lower ends in developing fluid, their vertical edges equidistant from a solid wall member, and spacing between chromatograms to permit air flow. The means comprise a rack for use in a developing tank and in which the chromatograms are vertically supported in spaced slits, the ends of which are equidistant from a wall member when in the developing tank.
