Influence of Menstruation upon Human Milk

162nd Report of the Peroxidase Reaction. (109th Human Milk Study.)

Abstract

Literature shows that Arakawa's reaction is frequently negative during the menstrual period. And it was proved by Sato and I sono²³⁾ (the 110th Report of the Peroxidase Reaction) that the cause for the negativity is the occurrence of methyl glyoxal like substance^* in milk in the menstrual period. In such milk as becomes negative to Araka-wa's reaction during the menstrual or premenstrual period (periodic with one month's cycle), lactose content will decrease; chlorin may increase.
