Abstract

During last years one uses and develops successfully the diagnostic analysis and therapy of malignant tumors. The basis for this analysis is the special feature of interaction between the laser emission of a certain wavelength and turnortropic exogenous photosensibilizers, which can concentrate in the pathological af— fected. sections and parts of the bbdy. Por diagnosis one usually uses the difference between spectral characteristics of the sensi— bilizer photoluminescence and the luminescence of the surrounding tissies. For therapy one uses the ability of the excited molecules of the sensibilizer to transact the excitation energy to the celli— colou oxygen. This causes the conversion of oxygen molecules from triplet—state to singlet—state of the excited molecule with high chemical activity,thus destructing the malignant cells in the non— thermal way.
