Abstract
1. Neutrophiles with pathological granules were 0-13% in the cases of healthy persons, being 5.3% in men and 5.4% in women in the mean value.
2. As to the result in 155 lactating women, neutrophiles with pathological granules were 8.6%, 11.7% and 16.6% in the Arakawa-positive, the weakly Arakawa-positive and Arakawa-negative group respectively.
3. Neutrophiles with pathological granules showed a higher count in the Arakawa-positive group than in healthy non-lactating women.
4. Neutrophiles with pathological granules were seen in a high percentage according to the weakness of Arakawa's reaction--in-creasing as Arakawa's reaction became weaker.
5. Cases in which neutrophiles with pathological granules were seen over 19% were 16% of all the cases belonging to the weakly A-rakawa-positive group, and were 32% of all the cases in the Arakawa-negative group.
6. Pathological granules in a high degree in number and inten-sity, such as are seen in the cases of pneumonia were not seen in apparently healthy lactating women.
