    摘要： The present invention relates to an oral preparation of N-hydroxy-4-{5-[4-(5-isopropyl-2-methyl-1,3-thiazol-4-yl) phenoxy]pentoxyl-benzamidine having improved bioavailability. More particularly, the present invention relates to an oral preparation comprising: N-hydroxy-4-{5-[4-(5-isopropyl-2-methyl-1,3-thiazol-4-yl) phenoxy]pentoxy}-benzamidine or pharmaceutically acceptable salt thereof; and one or more carbonates selected from the group consisting of alkalimetal carbonate, alkalimetal bicarbonate and alkaline earth metal carbonate, and/or one or more disintegrants selected from the group consisting of sodium starch glycolate, carmellose calcium and croscarmellose sodium. The oral preparation according to the present invention inhibits gelation of N-hydroxy-4-{5-[4-(5-isopropyl-2-methyl-1,3-thiazol-4-yl) phenoxy]pentoxy}-benzamidine or pharmaceutically acceptable salt thereof in the early stage of release, which increases dissolution rate and remarkably raises bioavailability.

    摘要： Disclosed is a composition for treating prostate cancer. The composition for treating prostate cancer comprises as an effective ingredient a radioisotope-chitosan complex that includes a therapeutic radioisotope emitting beta radiation and chitosan. Also, the present invention discloses a kit for preparing the composition. When directly administered to a prostate cancer tissue, the radioisotope- chitosan complex is deposited in the applied target site while not leaking from the applied target site, and strongly inhibits the growth of prostate cancer cells while minimizing the side effects of conventional therapies, including urinary incontinence, urethral stricture and rectal bleeding. In addition, the radioisotope-chitosan complex may be used as an effective therapeutic agent for hormone-independent prostate cancer that is resistant to hormone therapy.

    摘要： The present invention relates to a method for preparing a radioactive film for local radioactive treatment. More particularly, the present invention relates to a method for preparing a radioactive film comprising the steps of; dissolving 0.1˜14.5 weight % of a stable nuclide and 13˜32.5 weight % of a film-forming base for the total amount of a solvent in the solvent; applying a stable nuclide solution on a release paper by a coater and drying; and irradiating a stable nuclide film with neutrons in a nuclear reactor. A method for preparing a radioactive film according to the present invention provides a radioactive film having a uniform distribution of radionuclides and an even thickness. Therefore, the therapeutic efficacy of the radioactive film for selective treatment of a lesion may be maximized by attaching the radioactive film on a patient's skin or a mucous membrane and by direct radioactive radiation.
