The urinary protein in case of various kinds of fatigue and hypertension is almost the same as the blood plasma and has all components of the plasma protein. There were no qualitative differences between the urinary protein and the blood plasma protein. This fact can be proved by the experiments of anaphylaxis and that of the filter-paper-electrophoresis. Now according to the filter-paper-experiment, the author can state that the urinary protein of fatigue has comparatively small amount of albumin and large amount of γ-globulin, and the urinary protein of hypertension has the contrary.
