*Bone marrow smears showed 3 dicentrics on scanning.
small amounts, however, and glycosuria was demonstrated only in those that showed urine elevations of 2+ to 4--. Four urines showed a slight
amount of protein, but other examinations did
not reveal abnormalities which might be associated with proteinuria.
Biood Sugar Determinations
Fasting blood sugar analyses were carried out
on 8 people (all in the unexposed group) who had
shown urine positive for sugar on the previous survey. Of these, 4 showed elevated levels (Nos. 853,
884, 893, and 991). Non-fasting blood sugar determinations were carried out routinely on 72 people in the exposed and 125 in the unexposed
groups. Elevations > 160 mg % were foundin 4 of
these, | exposed (No. 29) and 3 unexposed (Nos.
932, 936, and 1042). The somewhat higherincidence of diabetes in the Marshallese people has
been commented on in previous reports.
Protein-Bound lodine
Since previous survey results had shown protein-bound iodine levels on the high side of normal, 14 sera were obtained on individuals for
repeat analyses this year. The levels varied be_tween 4.6 and 12.0 ng % with a mean of 8.6; these
are again generally on the high side of normal.

Total Urine lodine and Creatinine
The purpose of these analyses was to determine
whetherthe rather high protein-bound iodine levels
reported in the Marshallese might be related to
high iodine levels in the diet. Total iodine and creatinine analyses were carried out on 10 urine samples obtained from subjects who had previously
shown relatively high protein-bound iodine levels.
The levels for total iodine varied between 5.2 and
66.0 ug % (av, 18.6), and the creatinine levels
varied between 0.025 and 0.80 g/1 (av, 0.52).
These levels were considered: to be in the normal
range, although the creatinine levels were somewhat high because of alkalinity of the urine samples. Therefore it did not appear that the todine in
the diet could account for the generally higher
protein-bound iodine levels observed. The cause
of this slight elevation remains to beclarified.
