Morphology ofBlood Cells
Children of Exposed Parents
Examination of peripheral blood smears showed
no unusual cellular morphology in either the exposed or controls. A few bilobed lymphocytes were
seen in the differential smears 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 myeloid precursors in 5 marrows (see
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 leukocytic elements 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.
