The magnesia of the urine may be increased by giving magnesium 

 salts or burnt magnesia gr. xxx per day. 



Xanthin Calculi 



The indications for treatment are the same as those for the treatment 

 of uric acid calculi, tc which it is so closely related chemically. 





Cystin Calculi 



We know from experimental data that the excretion of cystin is 

 lessened on a low protein intake. For this reason the minimum 

 amount of protein should be used. Klemperer and Jacoby have de- 

 scribed a case of cystinuria where the administration of sixteen grams of 

 sodium bicarbonate daily caused the sediment of cystin to disappear from 

 the urine. Smillie has also shown that cystinuria is best treated by a low 

 protein diet with the addition of sufficient alkali to keep the urine alkaline. 

 He found that the addition of sodium bicarbonate did not influence the 

 body metabolism in cystinuria but simply rendered the excreted cystin 

 soluble.
