Abstract: The purpose of the present invention is to provide a dosing technique for rifampicin, the technique being capable of long-term administration by enhancing the direct transfer of rifampicin to the brain and by suppressing the hepatic first-pass effect. This pharmaceutical composition for nasal administration, which contains, as an active ingredient, rifampicins selected from the group consisting of rifampicin, derivatives thereof, and salts thereof, and is used for the prevention or treatment of dementia, is capable of long-term administration by enhancing the direct transfer of rifampicin to the brain and suppressing the hepatic first-pass effect.

Abstract: [Summary] [Purpose] The invention provides a novel therapeutic agent or prophylactic agent for cognitive disorders. [Solution Means] The invention provides an antibody that participates in antigen-antibody reaction specifically with tau protein that has been phosphorylated in the vicinity of Ser413 of SEQ ID NO: 1, and a therapeutic agent or prophylactic agent for cognitive disorders comprising as an active ingredient a peptide that has been phosphorylated in the vicinity of Ser413.

Abstract: A technique of administering rifampicin over an extended period of time, with reduced side effects. A medicine that is for nasal administration and is used to prevent or treat neurodegenerative diseases, contains a rifampicin selected from the group consisting of rifampicin, derivatives thereof, and salts thereof, and a resveratrol selected from resveratrol and derivatives thereof, has reduced side effects, and can be administered over an extended period of time.

Abstract: It is intended to provide a novel amyloid protein (human variant amyloid protein) useful as an antigen molecule or the like for improving a vaccine therapy. This human variant amyloid protein is a protein with deletion of Glu at 22nd, Ala at 21st, or Asp at 23rd in a normal (wildtype) amyloid protein (A?1-40, A?1-42, or A?1-43) consisting of 40, 42, or 43 amino acids.

Abstract: There is provided benzofuryl-&agr;-pyrone derivative represented by the following structural formula (I): 1

Abstract: There is provided benzofuryl-&agr;-pyrone derivative represented by the following structural formula (I): wherein R1 represents a hydrogen atom or an alkyl group of 1 to 5 carbons; R2 represents hydrogen, —CO—R5 or —SO2R6; R3 represents hydrogen, an alkyl group of 1 to 5 carbons, etc.; and R4 is a substituent attached to the 4-carbon, 5-carbon, 6-carbon or 7 carbon of the benzofuran ring; and their salts. The compounds are useful as therapeutic agent for hypertriglyceridemia, lipid metabolism enhancers, or prophylactic and/or therapeutic agents for arteriosclerosis.

Abstract: The human monoclonal antibody to the glycoprotein gpIII of varicella zoster virus (VZV), and hybridoma producing same, are provided. The hybridoma is obtained by immunizing human lymphocytes with gpIII antigen in the presence of a mitogen, and selecting a monoclonal antibody which reacts with a cell monolayer ELISA plate but substantially does not react with a cell homogenate ELISA plate.
