Abstract
The results of examinations of accumulation of bis-1(I- alanylo-N)-ethylo-deuteroprotoporfiryne (Ala-PP) in healthy tissues and superficial tumors of 10 patients are presented. Fluorescence imaging was carried out by means of a CCD camera, coupled with an image amplifier. As an excitation source a titanium laser was used. Contrary to healthy tissues, the tumor ones are characterized by the slight decrease in Ala-PP concentration during several days after injection of preparation what enables initial determination of a tissue character and next application of a selective therapeutic irradiation.
