The writer has completed a study of certain phases of metab-

 sented a very low tolerance for pentose and for lactose.

Metabolism studies in a case of diabetes insipidus, in a four- 

 year-old boy. 



By Jacob Rosenbloom, M.D., Ph.D., and 

 Harry T. Price, M.D. 



[From the Biochemical Laboratory of the Western Pennsylvania 

 Hospital, Pittsburgh, Pa.] 



For a period of nine days we have studied, in a boy suffering 

 from diabetes insipidus, the nitrogen metabolism and urinary 

 nitrogen partition; the sulphur metabolism and urinary sulphur 

 partition; the calcium, magnesium, and phosphorous metabolism, 

 the chloride metabolism and the fluid intake and output. 



The studies were carried out on low and high protein diets 

 and on low and high sodium chloride diets. In some respects the 

 condition seemed to be due to a defect of the kidney to secrete a 

 concentrated urine ; in other respects this was not so.
