Using mature male rabbits, following facts were found:
1) When the time elapsed between the drawing of blood was comparatively short (2 hours), and the amount of blood drawn was over about 3cc., the serum protein concentration was found to decrease whereas when the amount of blood drawn was limited to below one cc., no significant change was observed.
2) When the interval between the drawing of blood was lengthened (approx. 6 hours), there was found no significant change in the concentration of serum protein, irrespective of the amount of blood drawn.
3) Administration of parotin was found to lower the concentration of serum protein in comparison to the control animal irrespective of the amount of blood drawn.
