Abstract: The present invention provides a preventive or a remedy for penile erectile dysfunction, which promotes blood-flow in a penile sponge body over long time and thus induces erection while showing high safety without any adverse effect on a body as a whole, when externally administered to a penis. Use of a drug of the present invention enables to prevent or treat male penile erectile dysfunction and, at the same time, overcome a problem of female insertion impediment caused by increased resistance due to vaginal secretion disorder. Namely, a sexual life of patients (including aged persons) having coital dysfunction can be normalized and thus QOL can be improved.

Abstract: The present invention provides an inhibitor of the invasion of bone-marrow-derived vascular stem cells or inflammatory cells into blood vessel walls, a blood vessel restenosis inhibitor, and a preventive or therapeutic drug for angiitis or myocardiitis, each containing a phthalein dye compound as an active ingredient; and an instrument for treating blood vessels which is coated with a resin containing a phthalein dye compound or made of such a resin. Use of the drug of the present invention enables effective prevention of restenosis of a blood vessel after, for example, angioplasy. Moreover, it is possible to prevent the progress and disruption of a lesion of angiitis, myocarditis, or arterioscrelosis, for which no efficacious preventive or therapeutic method has been established so far, as well as microvascular ischemic diseases.

Abstract: The present invention relates to a therapeutic tool for vascular diseases, which is coated with a dye-containing resin that comprises one or more biocompatible dyes selected from the group consisting of sulfonic acid azo dye, phthalein dye, triphenylmethane dye, phenantridium dye, acrydine dye, xanthene dye, phenothiazine dye and cyanine dye; a medical treatment by the use of the therapeutic tool for vascular diseases; and a method of preventing vascular restenosis caused mainly through inhibition of migration of vascular progenitor cells by administering the medical treatment to a subject. Since the present therapeutic tool for vascular diseases is capable of staying in vivo for a long term, a medical treatment such as angioplasty (coronary angioplasty, peripheral angioplasty, cerebral angioplasty, etc.

Abstract: The present invention provides a medicine and an apparatus which can detect the sites and spreading of in vivo lipids by a two-dimensional image, thereby allowing diagnosis of diseases due to accumulation of lipids. According to the present invention, provided are a medicine for detecting in vivo lipids, comprising one or more components such as oxLDL and lyso PC, as an effective component, selected from a sulfonic acid blue dye having a radical —SO3?, a homidium, Metanyl yellow and Lissamin fast yellow, and an angioscopic system for obtaining a fluorescent image, which comprises a mercury-xenon lamp light source, a quartz fiberscope wherein the light guide part has 100 to 200 fibers and the image guide part has 7000 to 9000 fibers, a rotational exciting filter, an emitting filter, and a high-sensitive digital camera for picking up the fluorescence as a two-dimensional color image.
