Abstract
In a preceding papery1) I have made an investigation into the relation between the Arakawa reaction and the chlorine content of urine samples which were collected in the morning (9-10 a.m.) mostly from healthy lactating mothers, and found that the urine of Arakawapositive mothers is higher in chlorine content than the Arakawa-nega-tive urine. To further confirm this fact the present examination was undertaken using the whole day urine of healthy lactating mothers.
The chlorine content of whole day urine of Arakawa-negative mothers shows an average figure of-30, Q deviation as compared with that of Arakawa-positive mothers (Cf. Table 14). This result is in conformity with the result obtained in my preceding paper1) (the. chlorine content of theArakawa-negative-cases shows an average figure of -34% deviation as compared with that of the Arakawa-positive cases). Further, -in this experiment it is shown that Arakawa-negative mothers are generally poorer in the chlorine content and in the amount of 'hole . day urine than Arakawa-positive mothers. It is very probable that, viewed from the chlorine content and the amount of whole day urine, the Arakawa-negative human milk will pass for a B-avitaminotic milk, from the above cited literature even to the exclusion of other points of view. Viewed from the chlorine content of milk, blood and urine, the Arakawa-negative mother is rich in milk chlorin and poor in urine chlorin. Further, the amount of whole day urine of Arakawa-negative mothers is smaller than that of Arakawa-positive ones. So, generally spoken, there is a tendency to chlorine and water retention in the body of an Arakawa-negative mother.
