Abstract: The present disclosure relates to novel methods for using treprostinil or its derivative, or a pharmaceutically acceptable salt thereof, for the treatment and/or prevention of ischemic lesions, such as digital ulcers, in subjects with scleroderma (including systemic sclerosis), Buerger's disease, Raynaud's disease, Raynaud's phenomenon and/or other conditions that cause such lesions. The disclosure also relates to kits for treatment and/or prevention of ischemic lesions, which include an effective amount of treprostinil or its derivative, or a pharmaceutically acceptable salt thereof.

Abstract: The invention relates to a method for the treatment or prevention of diseases or conditions associated with vascular endothelium dysfunction or liver injury comprising the administration to a patient in a need of such treatment or prevention of a therapeutically or prophylactically effective amount of a compound selected from the group consisting of: wherein R represents hydrogen atom, CH3, OH, pyridyl (C5H4N), 1-methylpyridyl (C5H4N—CH3) or pyridyl substituted with hydroxy group ((OH)C5H3N), and X represents a physiologically acceptable counterion.

Abstract: The present invention provides nanoscale and microscale compositions useful for a variety of purposes, including the diagnosis and treatment of diseases. In one embodiment, the present invention provides a disease treatment system comprising a thermal induction agent and a radiation source, wherein the thermal induction agent comprises at least one carbon nanotube, at least one carbon microtube, or a mixture thereof.

Abstract: Compounds represented by the general formula: ##STR1## (where R.sub.1 is one member selected from the group consisting of CH.sub.2, CH.sub.2 CH.sub.2, CH.sub.2 O, CH.sub.2 S and CH.sub.2 SO; R.sub.2 is a hydrogen atom or a lower alkyl group having 1-4 carbon atoms or a benzyl group; R.sub.3 is a group represented by the general formula COOR.sub.4, the general formula NHCOR.sub.5, the general formula CONR.sub.6 R.sub.7, PO.sub.3 H.sub.2 or SO.sub.3 H; and n is an integer of 1-4) or salts therof are useful as therapeutic agents of autoimmune diseases such as systemic lupus erythematosus and nephritic diseases such as glomerulonephritis.
