The nitrogen of the urine and feces before and after this period of 

 high protein feeding is shown in Tables 8 and 9.

 NITROGEN IN URINE AND FECES IN INTESTINAL INFANTALISM ON A HIGH PROTEIN DIET 



(PATIENT F. S.) 



Despite a five-fold increase of food protein in the second period, the 

 nitrogen of the feces is not only not increased, but is actually decreased a 

 finding indicating that the high nitrogen of the feces on the usual lower 

 diet cannot be due to any inadequacy in the digestion and absorption of 

 protein. The results are in accord with the other evidence in indicating 

 that the nitrogen in the feces is of the same origin as that in normal feces, 

 that it is chiefly excretory and does not represent unabsorbed food residue. 



Occasional occurrence of acetonuria, a low carbohydrate tolerance, and 

 certain other features suggested the possibility of a disturbance in the 

 formation or storage of glycogen, such that the glycogen store was con- 

 stantly low and soon exhausted. 



To test this possibility, the respiratory quotient after 18 hours' starva- 

 tion was determined. The value for the non-protein respiratory quotient 

 was 0.79, a figure indicating the oxidation of a mixture of fat and carbo- 

 hydrate. There is, therefore, no considerable abnormality in the glycogen 

 storing capacity. 



Nothing abnormal in the digestion or absorption of fat could be found. 

 The feces showed normal amounts of total fat, fatty acids, and soaps. 

 Table 10 shows the distribution of fat in different forms in the feces 

 (McCrudden and Fales(rf)).
