Abstract

The experimental facts on the physiologic action of the ultraviolet rays may be divided into three outstanding groups of theoretical and practical importance: the effect on growth and nutrition, the inhibitive action on bacterial growth, and the influence on the antimicrobic resistance of higher organisms. Experimental work of recent years has been focused almost exclusively on the first problem, and these investigations on the action of ultraviolet rays on growth, nutrition and germination have yielded many conclusive results. On the other hand, the more ancient investigations on light as an anti-infectious and anti-inflammatory agent have not revealed much information of an exact nature. Most of the latter work has been based on clinical observations, but, convincing as clinical evidence may be in demonstrating the effectiveness of actinic rays in climatic cures, such experiments always fall short of proving scientifically the value of each individual factor in climatic treatment.
