Publication number: 20080069896Abstract: Antitumor agents with high antitumor effect have much side-effect, and its activity decreases when the toxicity decreases. Thus, satisfactory antitumor effects are not always obtained. Therefore, development of an antitumor agent having a high antitumor effect, with less side-effect and low toxicity is awaited. The present invention is to provide an antitumor agent of fine particles, wherein platinum chloride, chloroplatinic acids and hydroxyapatite are blend. Platinum chloride and chloroplatinic acids are platinum tetrachloride, tetrachloroplatinate, hexachloroplatinate, disodium platinum tetrachloride, disodium platinum hexachloride, dipotassium platinum tetrachloride, or dipotassium platinum hexachloride. The maximum particle diameter of hydroxyapatite is 1 ?m or less.Type: ApplicationFiled: September 26, 2005Publication date: March 20, 2008Applicant: Kabushiki Kaisha SangiInventors: Shuji Sakuma, Kiminori Atsumi, Keiichiro Kikukawa

Patent number: 5670827Abstract: A semiconductor integrated circuit comprises a conductive protein electrode, such as cytochrome c, deposited on the surface of an apatite insulating layer such as hydroxyapatite, fluorinated apatite or chlorinated apatite. The apatite insulating layer is thin film coated onto a substrate such that it is substantially C-axis (002) oriented, which allows the integrated circuit to be of small size while minimizing undesired electron transfer between electrodes because the conductive protein electrode adopts the orientation of the apatite insulating film.Type: GrantFiled: October 17, 1995Date of Patent: September 23, 1997Assignee: Kabushiki Kaisha SangiInventors: Shuji Sakuma, Kiminori Atsumi, Tsutomu Ishizaki
