[On particular physiological significance of ultraviolet part of spectrum for phototherapy successfullness].

Abstract

The paper describes features of human "biological clocks" functioning and possibilities of their correction by light flux with different spectrum characteristics in patients suffering from seasonal depressions. Phototherapy is used since early of 1980 years as non-drug method of therapy for seasonal depressive disorders. The research task: comparative study of phototherapy with different spectrum characteristics for correction of biorhythm disorders in persons with seasonal depressions. Groups of compare: 24 patients with recurrent depressive disorders in different years. The patients in the 1st group was treated by conventional management (in optical spectrum) of the phototherapy. The patients in the 2nd group were treated by original method, developed by the authors, with UV-A (360-380 nm) enrichment, modeling natural sun light. Comparison of symptoms involution depth and speed in patients with seasonal depressions revealed greater effectiveness of UV-A phototherapy compared with phototherapy in "optical spectrum".
