Here only the blood picture of infantile preberiberi (A. Sato) will be summarized. As to that of infantile beriberi and infantile B-avitaminotic dyspepsia, only such features as occurred in most cases of infantile beriberi and in all the cases of B-avitaminotic dyspepsia will be mentioned.
_??_
1. Red cell count: In most cases of infantile preberiberi red cell count was normal and in several cases of infantile preberiberi a decrease of the count was seen.
2. Blood platelet count: In all cases thrombocytosis was seen in a high degree.
3. Lymphocytes: Inmost cases lymphocytosis was seen, but some cases showed a lymphopenia. The difference is probably due to the dif-ference of stages of B-avitaminosis.
4. Neutrophiles: Neutrophile count showed a decrease in almost all the cases.
5. Eosinophiles: In the cases of infantile preberiberi, there was an inclination to eosinophilia.
6. Basophiles: Mast cells were within normal limits in number.
7. Monocytes: Monocytes showed an increase in the group of in-fantile preberiberi.
8. Ar neth's nuclear shift: In the cases of infantile preberiberi a nuclear shift to the right or to the left was seen.
9. The shortest peroxidase stain-time: There was no case
* with-out a prolongation of the shortest peroxidase stain-time, showing that all the cases were already in a state of B-avitaminosis.
10. Arakawa's reaction: All the cases were Arakawa-neg-ative, or all thier mothers secreted a milk negative to Arakawa's re-action.
Blood picture of infantile beriberi, though the cases examined in the present work were only five in number, will be described below in comparison with that of infantile preberiberi.
Red cell count was normal. Blood platelet count of infantile beri-beri was higher than in the cases of infantile preberiberi. An inclina-tion to lymphocytosis was seen, while lymphocytes showed a decrease or an increase in the cases of infantile preberiberi. Though there was an inclination to eosinophilia in the cases of infantile preberiberi, in some cases of infantile beriberi an eosiophilia was seen, and in others an eosinopenia. We cannot say that monocytosis was seen in the cases of infantile beriberi. Arneth's nuclear shift to the right was seen in three cases of all the five cases, and so we can assume that infantile beriberi is in a more advanced stage of B-avitaminosis than infantile preberiberi is from this stand-point alone. The prolongation of the shortest peroxidase stain-time was seen in all the cases and the stain-time was even five seconds in one case.
Now, we will describe the difference of the blood picture between infantile preberiberi and B-avitaminotic dyspepsia.
Except for an inclination to a decrease of eosinophiles and a nu clear shift to the left that was probably due to the dyspepsia, there was no remarkable change of blood pictures in the case of B-avitaminotic dyspepsia-blood platelet count was high and the shortest peroxidase stain-time was three seconds in 3 cases examined (Cf. Table 9).
The above stated was based on the absolute number of blood cells.
The number of our cases was not large, because, as stated above, we excluded cases with complications. So, the blood picture of B-avi-taminotic dyspepsia will be made a problem for future study with a much larger number of cases.
