Abstract
In the egg-yolk group, the activity of the alkaline phosphatase begins to increase its intensity in the first week, and increases gradually up to the peak of the fourth week, and decreases again from the fifth Week and declines further in the sixth week.
In the cholesterin group, no change of the activity was found throughout the whole observation.
In the rice grain group, on the contrary, the first week activity shows the same intensity as the highest activity seen in the fourth week of the egg-yoke feeding experiment, and later, however, during the whole period of time from the second week to the sixth, no fluctuation of the intensity of the enzyme activity was observable. The author is grateful for kind advices of Dr. Prof. T. Taniguchi.
