The components of the peripheral white blood cells (WBC) were determined before and after 10 min of submaximal ergometric work in two groups of subjects: 34 healthy Yemenite Jews with benign familial leukopenia (BFL) and 34 healthy Yemenite Jews without BFL. The mean ± SEM of the increase in the peripheral WBC following the effort in the control group was 2,606 ± 1,272 cells/mm3, due to the relative rise in the neutrophils, eosinophils, monocytes and lymphocytes. The identical ergometric work performed by BFL subjects, brought about a significantly lower increase (700 ± 865 cells/mm3) in the peripheral WBC, the majority of which were lymphocytes. It seems that subjects with this form of BFL lack granulocytes in the marginal pool.
