Abstract: An optical tomography apparatus has a measurement unit that divides light output from a light source into measurement light and reference light, that repeatedly scans a subject with the measurement light, and that causes a detector to detect interference between reflected light of the measurement light and the reference light, and a processor. The processor performs an acquisition process of are temporally sequentially acquiring tomographic images at the same transverse position in the subject based on a signal output from the detector. The processor performs a video image generation process of generating a synthetic image on a real time basis by synthesizing a new tomographic image frequently and one or more past images, and causing a monitor to display a real time video image formed from the synthetic image.

Abstract: In a freeze-drying method for producing a dried pharmaceutical compound or preparation, a first liquid is frozen, a second liquid is added to the frozen first liquid and is frozen thereon, and the frozen first and second liquids are freeze-dried together, in which at least one of said first and second liquids contains said pharmaceutical compound of preparation dissolved or suspended therein. The other liquid or liquids may be pure solvent (generally water) or may contain one or more other substances.

Abstract: Administration of an N-acylated amino acid in association with a penem or carbapenem antibiotic relieves or eliminates the renal problems associated with administration of the antibiotic alone. The amino acid derivative and antibiotic may be formulated together as a composition or administered separately, either simultaneously or sequentially.

Abstract: Improvement in determination of an enzyme activity in a substance having an enzymatic activity which comprises employing an aromatic primary amine derivative as a substrate and an iron complex treated with a peroxide as a color reagent.
