156. CEREBRAL RESPIRATION: DOG 



Dogs received basic dose of 20 mg/kg of morphine sulfate. (In using this table, it should be remembered that 

 morphine sulfate has a significant effect on blood respiratory characteristics [Rakieten, N., Himwich, H. E., and 

 DuBois, D., J. Pharm. Exp. Ther.^:437, 1934] ).

HI Increase or decrease from control level breathing air. /2/ Blood pressure decreased to a low level after blood 

 specimens obtained. HI Determination of adenosine triphosphate (acid- labile and ribose monophosphate) reveals 

 normal values in all classes of experiments except for low oxygen with acapnia, in which values about 25% lower 

 than normal were obtained.
