Abstract
I investigated the change of blood pictures of 17 “healthy” infants nursed with weakly Arakawa-positive milk on administration of vita-min B to them and to their mothers, and I came to the following conclusions:
1. In the cases in which the initial count showed a low value, red cell count increased gradually after administration of vitamin B (pro-bably to attain the normal value).
2. Blood platelet count decreased gradually after administration of vitamin B (probably to come down to the normal value) in the cases in which the initial count showed a high value.
3. When the total leucocyte count and the absolute counts of varieties of white cells showed abnormally high values, these counts decreased to lower values after administration of vitamin B (probably to come down to the normal value). On the other hand, in the cases in which the initial count of total leucocyte count and of absolute count of varieties of white cells showed abnormally low values, these counts increased to higher values (probably to go up to the normal value).
In a word, the blood picture of infants nursed with the weakly Arakawa-positive milk drew near the normal picture after administra-tiort of vitamin B.
4. As has been reported in a number of papers from our Laboratory, apparently healthy infants nursed with weaklyArakawa-positive milk are probably in a state of B-avitaminosis.
