Abstract
Multiple sclerosis and rheumatoid arthritis can be treated effectively using photodynamic therapy. In this protocol, a photoactive compound is administered, allowed to distribute in the effected subject, and the subject is then irradiated to activate the photoactive compound. Alternatively, the blood of a subject to be treated can be subjected to PDT extracorporeally. In the case of rheumatoid arthritis, localized treatment at the joints may also be employed.
