114. A Study of the influence o£ electricity on metabolism.^*^ 

 Matthew Steel. {Long Island Medical College.) In two ex- 

 periments, eleven days each, a normal healthy adult on a uniform 

 non-purin diet, was subjected for 30 minutes to Faradic sinusoidal 

 currents of uniform strength (the secondary coil was over the 

 primary 10 cm.) but of different frequencies of interruption, which 

 were 45 per minute in experiment I, and 90 per minute in experi- 

 ment II. The f ollowing Symptoms were noted : A languid and tired 

 feeling, strong desire to urinate, and increase in the daily volume of 

 urine varying from 100 to 200 c.c. per day. There was a sHght 

 increase in the total nitrogen and Creatinin nitrogen for the periods 

 of treatment. The amounts of the other nitrogenous constituents 

 were remarkably constant through all the periods. 



During the course of determinations of urea by the Benedict 

 method, urorosein developed in the specimens voided during the 

 period of the electrical treatment. Herter has shown a relationship 

 between the development of nitrites in urine and the appearance 

 of urorosein. The specimens which gave the urorosein reaction, 

 apparently as a result of the electrical treatment, responded strongly 

 to tests for nitrites, whereas the normal specimens (which did not 

 contain urorosein) were free from nitrites. 



This study will be continued with other kinds of electrical 

 currents.
