Organic Constituents of Saliva 



169 



Salivary uric acid was much lower than the uric acid of the 

 blood (approximately thirty per cent, of the uric acid of the 

 blood in most cases) as shown in the table. 



The salivary glands are apparently not readily permeable to 

 the glucose of the blood. In only one of the salivas studied 

 was there obtained sufficient reduction (Folin-Wu method) to 

 make possible an approximate estimation (0.006 per cent, cal- 

 culated as glucose). Although the blood sugar was increased 

 about fifty per cent, one and one-half hours after enteral ad- 

 ministration of 100 grams of glucose, glucose could not be de- 

 tected in the salivas of two individuals. 



Further work on other organic constituents of saliva is in 

 progress.
