It has already been shown by Arakawa2) that human milk negative to Arakawa's reaction is a milk from a B-avitaminotic body. The clinical experience of our Department is very much in favor of this opinion, but our Department has not yet given direct evidence of the existence of avitaminosis B in such a mother, though the reports of Ichimi13) and of Hirayama12) published from outside of our Department have shown that mothers with Arakawa-negative milk are mostly B-avitaminotic. In the present paper I examined the blood platelet count in 52 mothers with strongly Arakawa-negative milk and 48 mothers with completely negative milk. The platelet count was, as shown in Table V, decidedly larger in the latter. Taking into consideration the unanimous result shown by Ido, 14) by Kubo, 15) and by Nakamura16) that the blood platelet count is remarkably increased in beriberi cases, “healthy” mothers secreting human milk negative to Arakawa's reaction is, as may be safely deduced, already in a state of avitaminosis B.
