Abstract
In this investigation a total of 48 rats was employed, 16 controls and 32 pathological animals. The dietary technique has been described. 1
The blood determinations were made once weekly and the experimental period lasted 30 to 40 days.
In Tables I and II are submitted typical illustrations representative of the remainder of the group.
It will be noted from the tabular data that the vitamin D deficient animals showed the same range of concentration of blood lipids as the controls.
Further work in progress will establish whether a longer fast will eliminate the changes in metabolism due to absorption of food lipids, and will bring about less fluctuations in the normal and whether, by the use of the modified technique, avitaminotic rats will show any definite departure from the normal in concentration of blood lipids.
