PHOTODYNAMIC THERAPY METHOD USING PHOTOSENSITIZER AND CHEMICAL LIGHT FOR ACTIVATING PHOTOSENSITIZER

摘要

PURPOSE: A photodynamic therapy method is provided to obtain an effectiveness of therapy with a low cost by performing a photodynamic therapy by using chemical light as a light source for activating a photosensitizer. CONSTITUTION: A photodynamic therapy method comprises a step of mixing a photosensitizer and a vaseline by the ratio of 0.5:5 to 1.5:5, applying the mixture to the skin of a patient, and permitting the mixture to be fully absorbed into the skin over a time period of 6 to 8 hours; and a step of irradiating energy of 150 to 100J/cm¬2 to the lesion part of the patient, and restrictively irradiating chemical light having a wavelength of 490 to 670nm to the lesion part.
