Abstract: The purpose of the present invention is to provide an osteogenesis promoter that can be administered locally and systemically and that is suitable for clinical application. Provided is an osteogenesis promoter that contains, as an active ingredient, at least one compound selected from the group consisting of phenazopyridine hydrochloride, riluzole hydrochloride, tranilast, rabeprazole, indoprofen, nabumetone, luteolin, leflunomide, lansoprazole, methiazole, thiabendazole, albendazole, tiaprofenic acid, balsalazide sodium salt, and cyclosporin A, or a pharmaceutically acceptable salt thereof. Preferably, rabeprazole or lansoprazole, which are proton pump inhibitors, is used as an active ingredient.

Abstract: A screen-integrated speaker in which mutual interference among channels does not occur easily, a high quality sound and a wide range of frequency are ensured, flexible and light, and downsizing for storage and transport are easy owing to its easiness of rolling up and deployment under a multi-channel structure is provided. The screen-integrated speaker according to an aspect of the invention includes a screen mainly composed of a fibrous structure and an exciter mounted to the back surface of the screen. Preferably, a exciting panel is interposed between the exciter and the screen.

Abstract: The blood flow channel sections of an oxygenator and a blood resevoir are hydrophilized by treatment with an acid, an albumin solution, polyhydroxy methacrylate, corona discharge, plasma or ozone, so that it has highly improved weltability by the priming liquid and the blood to prevent blood foaming. The blood flow channel sections of a medical instrument may be additionally hydrophilized by treatment with a polymer containing hydroxyethyl methacrylate and methyl methacrylate or in addition thereto a poly(oxyethylene)-poly(oxypropylene) block polymer.
