Abstract: To obtain a composition for caries prevention, which has effects for efficiently suppressing demineralization and promoting remineralization and stability in keeping for a long time, 0.01 to 10% by weight of sodium carboxymethylcellulose having the etherification degree of 0.7 to 1.0 is used in a composition blended with a casein phosphopeptide-amorphous calcium phosphate complex (CPP-ACP) and/or a casein phosphopeptide-amorphous calcium fluoride phosphate complex (CPP-ACFP), a sodium carboxymethylcellulose, a viscosity regulator and water.

Abstract: A tooth surface treatment material and method to eliminate a smear layer, to deliver an inorganic component of a tooth structure in a dental cavity to the tooth structure to make a glass ionomer cement firmly adhere particularly to a dentin which includes an aqueous solution containing 2˜30% by weight of a water-soluble calcium salt and an acid which does not react with the calcium salt by ½ or less of the weight of the calcium salt and having a pH of 2 or less and an aqueous solution containing a water-soluble phosphate other than a calcium salt, or an aqueous solution containing 2˜30% by weight of a water-soluble calcium salt and an aqueous solution containing 2˜30% by weight of a water-soluble phosphate other than a calcium salt and an acid which does not react with the phosphate by ½ or less of the weight of the phosphate and having a pH of 2 or less, the acid-containing aqueous solution being first applied, and the other solution being subsequently applied onto the teeth s

Abstract: To simply and accurately detect initial dental caries without impairing the aesthetics, the detection material for initial dental caries contains 0.001 to 5% by weight of at least one dye selected from fluorescein sodium, fluorescein potassium, dibromofluorescein sodium, and dibromofluorescein potassium compounded in a solvent. It is preferred that the solvent is one member selected from water, ethanol, glycerin, isobutyl alcohol, ethyleneglycol, diethyleneglycol, triethyleneglycol, acetone, and propylene glycol, or a mixed solution of two or more of these members.

Abstract: A composition for remineralization of a tooth, adapting to a tooth surface demineralized due to dental caries and forming a compound within the tooth to gradually release a phosphate ion and a calcium ion therein, is comprised of a solution A to be first applied to a tooth surface, containing 1 to 30% by weight of a calcium salt, with the remainder being a volatile solvent; and a solution B that is an aqueous solution containing 1 to 30% by weight of a phosphate and preferably a fluoride in an amount of 0.0001 to 5% by weight, where at least one of the solution A and the solution B preferably further contains a surfactant in an amount of 0.0005 to 1 % by weight.

Abstract: Compounds including 1-(biphenyl-4-yl)methyl-1H-1,2,4-triazoles and 1-(biphenyl-4-yl)methyl-4H-1,2,4-triazoles each having a (2,4-dioxopyrrolidine-5-ylidene) methyl or (2,4-dioxo-tetrahydrofuran-5-ylidene)methyl group as the substituent at the 2′-position and salts thereof are lowly toxic and highly safe and are useful as an angiotensin II antagonist. Thus, these compounds can be used in medicines, which contain these compounds as an active ingredient.

Abstract: Cross bars 18, to which workpiece holders 19 are attached, are provided across a press line L, together with feed beams 14 between which the cross bars are installed and which are suspended from the lift beams 13 and can move freely in the horizontal direction of the press line. A feed and transfer device 52 can move the feed beams freely in the horizontal direction of the press line. A connecting rod 56 connects the feed beams and the rack beam in a freely rotatable manner. A connecting link 60 connects a point in the vicinity of an intermediate portion of the connecting rod to a bracket 58 installed on the rack beam, in a freely rotatable manner. An operating direction changeover mechanism 61 converts the differential movement caused by the curvature of the press transfer motion, produced in the feed beams when the lift beams are raised or lowered, into a horizontal movement in the direction of the press line in synchronism with the raising or lowering of the lift beams.
