COMPARATIVE MEASUREMENTS OF Q02 IN 3 DIFFERENT SALINE MEDIA 



C. DISCUSSION OF RESULTS 



I. Comparison of the Qq^ values obtained in the 3 media 



Kidney cortex, spleen and liver gave about the same Q02 in all three media, but 

 differences exceeding 10% were found in brain cortex and in liver. A comparison of the 

 data from Tables V and VII (see Table IX) shows that the average Q02 values for brain 

 cortex in medium II were between 37 and 87% higher than those obtained in medium III. 

 In the case of the liver the differences were smaller; they are of doubtful significance in 

 the small animals (mouse, rat) and increase approximately (though not strictly) parallel 

 with the body weight of the species, being greatest in cattle and horse.
