Abstract

Severe Criticism of Treatment by Ultraviolet Radiation  The annual report of the medical research council for 1927-1928, just published, contains a searching criticism of the uses of ultraviolet rays in the treatment and prophylaxis of disease. The report declares that prolonged researches give no scientific reason to suppose that the treatment of rickets, or the supply of vitamin D to the body for any other purpose, is better effected by ultraviolet rays falling on the skin than by the direct provision of the necessary food values. The general evidence from the vigor of the human life enjoying natural food supplies in the most northern latitudes points in the same direction. Since the invisible rays of ultraviolet radiation were found to hold the nutritive properties of sunlight, it was natural to suspect that artificial lamps, rich in ultraviolet rays, might be an effective substitute for the missing sunshine in our cities.
