The effects of adrenaline on the oxygen transport properties of Salmo gairdneri blood.
1. An injection of adrenaline into the dorsal aorta of Salmo gairdneri caused an increase in the dorsal aortic O2 content at 7 and 14 degrees C. 2. At 7 degrees C the number of erythrocytes in the dorsal aorta increased as indicated by the increases in both the Hct value and the haemoglobin concentration. 3. At 14 degrees C the erythrocytes in the dorsal swelled owing to the injection of adrenaline; this shifts the O2 dissociation curve to the left and in this way increases the dorsal aortic O2 content.
