The gross chemical changes in the liver in dietetic necrosis

Abstract

oil it is evident that the vitamin D content of this oil shows striking variation, which follows the same trend as the vitamin A content in the samples studied (to be discussed in the forthcoming paper by Shorland, 1945). SUMMARY 1. Prophylactic bone ash analysis was used to determine the vitamin D content of three New Zealand fish oils. The vitamin D content in i.u./g. was found to be: whole-body eel oil, 25; ling liver oil, 260; groper liver oil (I), 5300; groper liver oil (II), 19,000. The potency of the two samples of groper liver oil shows a striking variation, and in the same direction as that of the vitamin A content of these oils.
