  • Patent number: 9028647
    Abstract: An adhesive of the invention is used for polarizing plate to provide a transparent protective film on at least one side of a polarizer and comprises a resin solution comprising a polyvinyl alcohol-based resin, a crosslinking agent and a colloidal metal compound with an average particle size of 1 nm to 100 nm, wherein 200 parts by weight or less of the colloidal metal compound is added to 100 parts by weight of the polyvinyl alcohol-based resin. The adhesive for polarizing plate can reduce the occurrence of knicks.

  • Publication number: 20110189299
    Abstract: The invention provides a pharmaceutical composition that can be used for efficient administration of low-molecular weight drugs and polymeric compounds such as peptides and proteins by methods other than injection, as well as a method for producing the composition. The pharmaceutical composition is for transmucosal administration and comprises (a) a drug having a positive or negative charge at a predetermined pH, (b) a pharmaceutically acceptable small particle and (c) a pharmaceutically acceptable surface-coating polymer capable of being electrically charged at the pH, wherein the surface of the small particle is coated by the surface-coating polymer, the drug is immobilized on the surface of the small particle via the surface-coating polymer, and a complex is formed by a noncovalent interaction between the small particle and the surface-coating polymer and a concurrent electrostatic interaction between the surface-coating polymer and the drug.

  • Patent number: 7442682
    Abstract: Compositions and methods are disclosed for the treatment of diabetes and related diseases using peptides with incretin hormone activity. Preferably, the peptide with incretin hormone activity is GLP-1, exendin or an analog of GLP-1 or exendin. The peptides with incretin hormone activity are administered transepithelially using a transepithelial carrier peptide. The transepithelial peptide contains sufficient amino, guanidine or amidino groups to stimulate transepithelial delivery. In some embodiments, the transepithelial carrier and the peptide with incretin hormone activity are embedded in a pressure sensitive adhesive layer of a plaster or patch.
