Abstract: The present invention provides: a method for producing stolon-forming plant having an improved tuber production ability as compared with a corresponding wild strain; and a stolon-forming plant produced by the method. The present invention also provides: a method for producing a stolon-forming plant having an improved stolon formation ability as compared with a corresponding wild strain; a stolon-forming plant produced by the method; and a kit for improving a stolon formation ability of a stolon-forming plant. The method of the present invention is a method for producing a stolon-forming plant having an improved tuber production ability as compared with a corresponding wild strain, the method including the step of introducing, into a stolon-forming plant, a Ran gene derived from Citrullus lanatus.

Abstract: An aqueous resin emulsion is disclosed. The emulsion is obtained by emulsion copolymerizing a monomer mixture comprising (a) an acrylic acid fluoroalkyl ester derivative, (b) an acrylic acid derivative, and (c) a polyfunctional monomer for internal cross-linking, in an aqueous medium. The emulsion shows excellent polymerization stability in emulsion copolymerization for the preparation thereof and excellent dispersion stability in an aqueous medium.

Abstract: A drug administration material for continuously administering an active drug at a controlled rate through an integument or mucous membrane, which comprises a drug-retaining layer having provided on at least one side thereof a drug administration layer which continuously feeds an active drug to an integument or mucous membrane, said drug administration layer comprising a porous membrane containing in pores thereof a liquid having a limited solubility for the active drug.

Abstract: An antiphlogistic analgesic adhesive which comprisesa flexible substrate andan indomethacin containing pressure-sensitive adhesive layer closely contacting said flexible substrate, wherein said pressure-sensitive adhesive layer comprises a mixture of(a) indomethacin,(b) a copolymer of (i) an alkyl acrylate having 4 to 11 carbon atoms in the alkyl moiety and (ii) a functional monomer having a functional group in the molecule thereof and/or a vinyl monomer, which has pressure-sensitive adhesive properties at room temperature, and(c) an absorption accelerating assistant which maintains said indomethacin in a solubilized state in said copolymer and has skin diffusibility.

Abstract: An antibacterial and antifungal material comprising a polymer containing carboxyl groups in an amount of at least about 0.008 milliequivalent per gram of the polymer and antibacterial and antifungal metallic ions ionically bonded to the carboxyl groups in an amount of at least about 0.0009 millimole per gram of the polymer.
