SPECIFIC-DYNAMIC EFFECT OF PROTEINS 533 



accepted in case of maize, there is no reason why it should 

 be debated for the proteins in general. 



Contrary to the attempt to refer the specific-dynamic 

 effect of protein to a heightened renal activity, Tangl has 

 proved that it is manifested as well after the kidneys have 

 been extirpated. 39 



Gigon takes the middle ground between the Zuntz and 

 the Eubner hypotheses, accepting the digestive work as 

 playing an important part. Although the economy in its 

 minimal metabolism is independent of the immediate 

 introduction of food, there is to be observed after protein 

 introduction an increase of protein combustion in which, too, 

 processes of intermediate conversion of protein into carbo- 

 hydrate and of the latter into fat are involved. 40
