Abstract
In this communication a report is made on the effects of animal viruses on the endogenous respiration of host tissues.
The results obtained are summarized as follows.
When the metabolism of tissues is to be studied by means of the Warburg manometer, it would be worthy to discuss whether the endogenous respiration increases or derceases.
The endogenous respiration can either increase or decrease with virus or RDE. Therefore, the present writers believe that the tendency is an absolute, non-variable state which fluctuates according to the germinal layer of host tissues.
The ectodermal host tissues (brain) have a tendency to decrease and the mesodermal and endodermal host tissues (erythrocytes, lung and liver) have a tendency to increase the endogenous respiration.
All these findings would indicate that a common component exists between the substrate of endogenous respiration enzyme and the important part of receptor of host tissues.
