STUDY OF TRANSFUSED BLOOD : I. THE PERIODICITY IN ELIMINATIVE ACTIVITY SHOWN BY THE ORGANISM.
Group IV transfused blood in a recipient of unlike group is eliminated by a blood-destroying activity of the body. This blood-destroying activity is periodic both in men and women, and in women coincident with menstruation. The elimination of the transfused blood probably takes place as part of a period of blood-destroying and blood-producing activity of the body, although direct evidence to this effect is so far lacking.
