Abstract: A sustainedly releasing agent for medicines comprising a non-crosslinked type anion-exchange resin represented by the general formula (I): wherein R1 represents aralkyl or alkyl, each of R2 and R3 represents lower alkyl, R4 represents a hydrogen atom or lower alkyl, X− represents a physiologically acceptable counter ion, n represents 1-3, and p represents a mean degree of polymerization, respectively, as well as a sustainedly released medicinal composition comprising the sustainedly releasing agent and a hypolipidemic agent.

Abstract: The present invention relates to iodine demand disinfectants. It relates in particular to a process for preparing a polyiodide-resin for use as an iodine demand disinfectant wherein a porous strong base anion exchange resin in a salt form, is contacted with a material capable of donating a member absorbable by the resin so as to convert the resin to the polyiodide-resin. The adsorbable member is selected from the group comprising I2 and polyiodide ion having a valence of −1. The process is characterized in that conversion of the anion exchange resin to the polyiodide-resin is effected at elevated temperature and elevated pressure, the elevated temperature being 100 degrees C. or higher, the elevated pressure being greater than atmospheric pressure. The present invention also relates to disinfectant substance comprising an iodine (impregnated) resin as produced by the above process.

Abstract: The present invention relates to methods in which ion exchange resins are used to reduce the amount of substances which interfere with nucleic acid hybridization in samples. The methods also stabilize the samples. Kits containing the ion exchange resins render the methods convenient to use.

Abstract: This invention provides a hydrophilic membrane wherein a hydrophilic cellulose derivative of a number average molecular weight of 2000˜8000 is adsorbed irreversibly to a hydrophobic membrane of an aromatic polymer. Since an amount of leaching substances is extremely small, the membrane can be used suitably in such fields as medical applications, electronics, etc. where even a quite small quantity of leaching substances from the membranes is limited especially small.

Abstract: Disclosed are cholesterol-depressant, coated or non-coated tablets for oral administration, which comprise an anion exchange resin of formula (I): wherein X represents a physiologically-acceptable counter ion; and p represents an average degree of polymerization, and is larger than 10,000, silicon dioxide and crystalline cellulose, but not containing water. The non-coated tablets are preferably coated with cellulosic substances. The tablets are easy to take, as being not bitter. The dose of the tablets can be decreased, since the tablets can contain a large amount of the active ingredient. The mixture comprising the constituent components can be directly tabletted in the absence of water.
