with the lymphocytes, the platelet counts-are the
highest yet attained since exposure. However, the
ever, the other blood elements in this group of
males do not appear lower than in the unexposed
group. A general anemic tendency in the Marshallese (combined exposed and unexposed groups)
is borne out bythefinding that 78% of the females
have hematocrits of 36% or less and 54%of the
males have hematocrits of 38% or lower.
unexposed group also showed an increase in mean
platelet count compared with last vear; but the
exposed group levels arestill significantly below
the unexposed (males, <10, —16%; >10, -11%;
and females, all ages, —9%). This is also borne out
by the following findings: (1) 22% of the exposed
group havelevels below 250,000 compared with
only 7% in the unexposed people; (2) the scattergrams (Figures 13 and 14) show more counts
below than above the unexposed mean curve in
Counts in the Ailingnae group.
From Table 4
it can be seen that the counts in the 18 people of
this group averaged nearly the same for the various blood elements as did the counts in the more
