Abstract
The ileal and colonic excreta were collected, weighed and analyzed separately. In one patient a Ca and P balance study was made. The diet was varied in bulk and in its content of water, Ca and P. The content of the terminal ileum was acid in two of three cases; the third case gave values approaching neutrality. In all three patients the colon failed to excrete significant amounts of Ca or P (3 to 4 mgm. per day). Hydration increased the wet and dry weight of the ileal elimination. Viosterol and para-thormone produced a diuresis and a decrease in wet and dry weight of the ileal excreta, chiefly the wet weight, indicating a better general absorption from the small intestine. Although the total amount of Ca and P lost through the ileum was decreased, the amounts per gram of dehydrated ileal excreta increased, showing that viosterol and parathormone did not increase the absorption of Ca and P specifically.
