Influence of Vitamin B on Arakawa's Reaction and Lactic Acid Content of Human Milk

144th Report Report of the Peroxidase Reaction. (91st Human Milk Study.)

抄録

In the preceding papers¹⁾²⁾, I ascertained that Arakawa-negative milk contains generally a larger amount of lactic acid than Arakawa-positive milk, as Yamada³⁾ and Sato⁴⁾ already stated. In the present paper, I was able to reduce the amount of lactic acid in Arakawa-negative milk by a subcutaneous or peroral administration of vitamin B to 12 lactating mothers with Arakawa-negative milk. From this outcome of my own experiment and Kitamura's¹⁶⁾ result, we may conclude that Arakawa-negative milk is a milk from a B-avitaminotic body from the view point of lactic acid, and it is then quite natural that such a milk can be made poorer in the lactic acid content by an administration of vitamin B.
