Abstract: Medicaments comprising a compound represented by the following formulas: wherein, R1 represents hydrogen atom or a C1-6 alkyl group; R2 and R3 represent hydrogen atom or a C1-6 alkyl group, or R2 and R3 may combine together with the carbon atoms of the phenyl ring to which R2 and R3 bind to represent a 5- or 6-membered ring; R4 represents hydrogen atom, a C1-6 alkyl group, a C1-6 alkoxyl group etc.; R5 represents hydrogen atom, a C1-6 alkyl group, or an aryl-substituted C1-6 alkyl group; R6 represents hydrogen atom or a C1-6 alkyl group; X represents —NR7—, —NO—, —O— etc. in which R7 represents hydrogen atom, a C1-6 alkyl group etc.; and Y represents a phenylene group or a pyridinediyl group, which are useful for preventive and therapeutic treatments of diabetes and complications of diabetes.

Abstract: Polymer particles including polysiloxane is disclosed. The polymer particles are prepared by condensing at least one organosilane or organosiloxane compound in the presence of organic polymer particles which are prepared from specific monomers and dispersed in an aqueous medium. The polymer particles possess excellent water resistance, weatherability, water repellency, adhesion, and flexing resistance, and thus are useful as water paints, coating agents, carpet packing material, floor polishing agents, cementing medium, and the like.

Abstract: The present invention consists of a vibrating element for ultrasonic injection in which the edged portion for atomizing liquid includes helical screw threads having either a uniformed diameter or varying diameters.
