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. By performing a medical treatment such as angioplasy using the instrument of the present invention for treating blood vessels, events of vascular restenosis can be effectively prevented.
