Studies on the Fat-Soluble Growth-Promoting Factor

Vitamin D

“…Thereafter, progress was extremely rapid. Thus Goldblatt 8 t Soames (1923) showed that the liver stored an antirachitic factor. This was confirmed by Steenbock & Black (1924) who found that liver tissue from irradiated rats also protected against rickets, suggesting that uv light exerted its effect by leading to the production in the body of a transportable antirachitic factor.…”

Landmark Discoveries in Calcium Metabolism Review of Literature

“…Three teams of scientists -Hume & Smith [27], Goldblatt & Soames [28] and Steenbock & Black [29], confirmed that sunlight (UV light) is a source of vitamin D in 1924 by their experiments on rats [27][28][29]. Hess & Weinstock [30] simultaneously reported that UV irradiation of food not having anti-rachitic factor induced its production in these food items and could be used as a method to enrich food to improve public health [30].…”

The Supposed Influence of Irradiated Air on Growth

“…It has been shown by Korenchevsky [1921], and Goldblatt [1923] that the bones of rats fed on the -A diet used here do not have a normal calcium phosphate content. The diet is rather low in calcium, It should be stated that none of the rats showed any macroscopic signs of rickets-the predominating feature in autopsy being the almost complete absence of subcutaneous fat.…”
