METHOD FOR DIAGNOSTICS AND PHOTODYNAMIC THERAPY OF acne vulgaris Russian patent published in 2005 - IPC

FIELD: medicine, dermatovenerology.

SUBSTANCE: one should perform diagnostics with the help of fluorescence spectrums of affected sections. Section being of own intensive fluorescence should be irradiated with light at wave length being 630±10 nm and energy density 10-4500 J/sq. cm, sections which has no own intensive fluorescence should be applied with an applicator containing 2-20% solution of 5-aminolevulinic acid and after exposure and applicator's removal they should be irradiated with light at wave length being 630±10 nm and energy density of 10-4500 sq. cm. The flow of irradiation process should be controlled due to fixing fluorescence spectrums at affected skin sections before irradiation, after the use of applicator that contains 5-aminolevulinic acid, after irradiation, moreover, irradiation should be stopped at decreased concentration of porhyrins being below therapeutic values. The innovation decreases cutaneous fatty secretion, quantity and density of eruption.

EFFECT: higher accuracy and efficiency of diagnostics and therapy.
