Abstract
1. Lymphocytes with azurophil granules were 26.3% on an aver-age in the cases of healthy persons.
2. Based on the result of investigation in 201 “healthy” lactating women, lymphocytes with azurdphil granules were 30.5%, 19, 0% and 14.6%. on an average in the Arakawa-positive, the weakly Arakawa-positive and the Arakawa-negative group respectively.
3. Lymphocytes, with azurophil granules showed a higher count in the Arakawa-positive group than in healthy non-lactating women.
4. Lymphocytes with azurophil granules were seen in ever small-er percentages according to the weakness of Arakawa's reaction: The completely Arakawa-negative women showed even a smaller percentage of the lymphocytes with azurophil granules than the weakly Arakawa-positive women.
5. Cases in which lymphocytes with azurophil granules showed an absolute count over 600 were 69%. of all the cases belonging to the Arakawa-positive group, were 25% of all the cases belonging to the weakly Arakawa-positive group, and 0% in the Arakawa-negative group.
6. As to the occurrence of azurophil granules in different-sized lymphocytes; large lymphocytes were the highest in percentage and middle-sized.lymphocytes the next highest. There were only a few or almost no small lymphocytes with azurophil granules.
