  • Therapy of auto-immune disease by a photochemotherapeutical method
    Patent number: 6653337
    Abstract: As a novel photochemotherapeutical method for the treatment or prevention of an auto-immune disease, there is provided a method for treating an auto-immune disease, which comprises administering to the patient mono-L-aspartyl chlorin e6 or mono-L-glutamyl chlorin e6 or a pharmacologically acceptable salt thereof, followed by subjecting the blood vessel blood of the patient containing the administered compound to exposure with an ultraviolet ray or a laser light, thereby to excite said compound photochemically. This method is effective to decrease the level of auto-antibody in the blood of the patient and is also of high safety.
