METABOLISM IN ATROPHIC ARTHBITIS 



TABLE 34 



METABOLISM IN A CASE OF ATROPHIC ARTHRITIS 



We have, in addition, the results of one metabolism observation 

 (Table 35) on a patient after recovery from a trophic arthritis. This is 

 the same patient whose metabolism in the active stage of the disease is 

 shown in Table 31. 



In all four cases of atrophic arthritis there is a decided negative cal- 

 cium balance. In two of the cases there is at the same time a retention 

 of magnesium ; only one of the four shows a negative magnesium balance. 

 As in the case of hypertrophic arthritis, the negative calcium balance is to 

 to attributed primarily to loss through the feces, the amount of calcium 

 in the feces in these cases running from 90 to 97 per cent of that in 

 the food.
