Effects of ultraviolet rays on blood Ca content. Leicher (Stralenterapie, Bd. XIX, H. 2)

Abstract

In the literature there are indications that when exposed to these rays the Ca content in the blood increases. Studies of the author, made on 60 persons aged from 4 to 65 years, show that this is not entirely true: the author observed from the action of ultraviolet rays increased Ca content only in those cases where it had previously been reduced against the norm; in those individuals who had normal Ca content, its change after lighting was not observed.
