CHEMICAL COMPOSITION OF CUTANEOUS EFFUSIONS 

 ( Epstein ) 



The non-protein constituents, such as urea, uric acid, and creatinin, 

 occur in transudates and exudates in approximately the same concentration 

 as in the blood. Creatin occurs only in small amounts in transudates, but 

 is present in exudates in the same amounts as in blood. Fat and choles- 

 terol occur in small amounts in transudates, but in large amounts in 

 exudates. Analyses of the non-protein constituents of three fluids are 

 reported by Denis and Minot(a) (Table III), and are compared with the 

 composition of the blood, withdrawn at the same time. Denis and Minot 

 have shown that the content of edematous fluids in urea, uric acid, and 

 cholesterol may be easily influenced by diet. Javal and Adler have also
