  • Publication number: 20080138437
    Abstract: Due to the toxicity of antitumor agents, use of antitumor agents is limited, and thus, it is desirable to develop auxiliary agents or antitumor agents that have the effect of reducing toxicity while maintaining the antitumor effect of antitumor agents. The present invention provides antitumor agents mixed with particulate hydroxyapatite as an auxiliary agent.

  • Publication number: 20080069896
    Abstract: 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.

  • Publication number: 20070166362
    Abstract: Transdermal and transmucosal preparations are often insufficiently absorbed. Thus, there is a need for additives that can enhance the transdermal and/or transmucosal absorption of various drugs. The present invention provides compositions for enhancing transdermal and/or transmucosal absorption, comprising a hydroxyapatite and essential ingredients. The hydroxyapatite has a maximum particle size of 1 ?m or less, preferably 0.1 ?m or less, and the content of the hydroxyapatite relative to a drug to be formulated ranges from 0.1 to 1000 weight percent.

  • Patent number: 5723401
    Abstract: A catalyst for contact conversion of lower aliphatic alcohols such as methanol to form petroleum type hydrocarbons comprises one or more metals and/or metal ions supported on a phosphate carrier. Preferred metals include transition metals such as Ti, Ni, Cu, Zn, Rh, Ag, Ir and alkali metals, alkaline earth metals, Al and Sn. The phosphate carrier is preferably aluminium phosphate, zirconyl phosphate, magnesium phosphate, barium phosphate, zinc phosphate or a calcium phosphate compound. The metal should amount to 0.1 to 30% by weight with respect to the phosphate carrier. This catalyst is used to contact convert lower aliphatic alcohols to produce the gasoline type hydrocarbons at a reaction temperature of 200.degree. to 600.degree. C. and a supply rate of 0.75 to 3.0 weight units of alcohol per weight unit of catalyst per hour.

  • Patent number: 5670827
    Abstract: 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.
