Studies of Basophils

Abstract
Numbers and morphology of circulating basophils of 694 human subjects and 45 rabbits were examined. The position of the granules in the basophils was used to determine cell age. Young adult human females had a higher mean of basophil num-bers than the males in the same age group. Geriatric females had a lower mean than their male counterparts. Sexually mature female rabbits had a higher average number of basophils than immature females or mature and immature male animals. Basophil differential counts showed that young adult female humans and mature female rabbits had the fastest turnover of basophils among the groups examined.
