Blood Platelet Count of Sucklings according to Arakawa's Reaction of Their Mothers

121st Report of the Peroxidase Reaction

Abstract

1. Blood platelet count of infants showed an increase in the case of mothers with negative Arakawa's reaction, being 435, 384 and 301 thousand thrombocytes in the Arakawa-negative group, in the group of intermediate Arakawa's reaction, and in the normally Arakawa-positive group respectively.
2. Red cell count was 5, 140 and 5, 130 thousand cells in the strongly Arakawa-positive group and in the group of intermediate Arakawa's reaction, while a slight anemia was seen in the Arakawa-negative group showing 4, 930 thousand on an average.
3. In the cases in which infants and their mothers had not been taking vitamin B preparations, platelet count was within normal (317 thousands) in the Arakawa-positive group, but an increase of platelet count (397 thousands) was seen in the cases with intermediate Arakawa's reaction, and the maximal average count (458 thousands) occurred in the Arakawa-negative group.
4. In the cases in which infants and/or their mothers had been taking vitamin B preparations, blood platelet count was a moderate surplus over the normal limit even in the Arakawa-negative group.
