MILK IRRADIATED BY THE CARBON ARC LAMP: A CLINICAL AND LABORATORY STUDY OF RICKETS

In the course of the past five years we have reported our experiences, clinical as well as experimental, with various activated substances.1 The first of these communications dealt with irradiated cholesterol, ergosterol, yeast and dried milk. Those which followed were concerned more particularly with the therapeutics of irradiated ergosterol (viosterol), with its dosage and standardization. Last year a somewhat different aspect was considered,2 and a clinical test was reported of the milk of cows which had been fed irradiated yeast. Concurrently with these various clinical papers, communications have been made, in some instances in cooperation with other laboratories, dealing more particularly with laboratory or technical features. The most recent one, published in conjunction with Supplee and Dorcas, gave in detail the energy requirements for the antirachitic activation of irradiated milk3 and showed the high degree of potency of activated dry milk. The present paper concerns itself more
