Abstract

A medical preparation for treating arthrosis, arthritis and other rheumatic joint diseases comprises a suspension consisting of one-shelled or multi-shelled nanoscalar particles composed of a core containing iron oxide and of an inner shell with groups capable of forming cationic groups or, optionally, of at least one outer shell with neutral and/or anionic groups. Radionuclides and substances, said substances being cytotoxically active when subjected to heat, are bound to the inner shell. The preparation that is injected into the joint cavity and subjected to an alternating electromagnetic field promises an excellent treatment outcome due to the high rate of phagocytosis and the trimodal combinatorial effect of thermotherapy, radiotherapy and chemotherapy.
