加速回転中の血液水分量について

抄録

Previously, I had studied the water content of the blood after stimulation by accerelated rotation and found its decrease due to a sympathicotonic change brought about in the living body by accerelated rotation through labyrinth. This time, however, I made an observation of the water content of the blood during stimulation by accerelated rotation, and found that the water content of the blood was decreased throughout the duration of stimulation, showing that the living body was in sympathicotonic condition. Further, by giving an intravenous injection of sodium bicarb-onate solution beforehand, the decrease in the water content of the blood during stimulation could be prevented.
