Morphology of Blood Cells
Children of Exposed Parents
Examination of peripheral blood smears showed
no unusual cellular morphology in cither the exposcd or controls. A few bilobed lymphocytes were
seen in the differential smcars of both exposed
and unexposed people but no counts were made.
Price-Jones curves in the past have showna slight
microcytic tendency in the red cells. Bone marrow
smears were obtained on 9 exposed Rongelap people. These examinations showed a reduced M/E
ratio in 8 of 9 cases with abnormalities of the erythroid and mycloid precursors in 5 marrows (see
Table 11).
Peripheral blood elements of 24 children with
parents one or both of whom had been exposed
were compared with those of 50 children with unexposed parents. These children were <8 yr of
age. The results are presented in Table 12 and
Figure 37. There appeared to be a slight depression of Ieukocytic clements in both male and female children of exposed parents but a slight increase in platelets. Thus the findings reported last
year of male children (but no female) of exposed
parents showing depression of all blood elements
is not substantiated in this year’s findings.
