exposure. In other patients, liver function gradually recovered, and clinically significant liver
disturbances have not been found. For example,
CCF test was positive in most of the patients
in 1955 survey (i} years), while CCF test in
1957 examinations was negative in all the cases.
6. Other Studies
The study of leucocyte chromosomes was made
with peripheral blood culture method. The
results of the study, however, were not sufficient
enough to be presented.

1964 Medical Survey
As already mentioned, we have tried to perform medical survey on these irradiated persons
on an annualbasis. However, sufficient examination was impossible by several reasons.
This 1964 survey was carried out as follows:
1) Thirteen persons were examined at the
National Institute of Radiological Sciences,
and one person at the Tokushima Univerr
sity Hospital, under hospitalization.
2) Four persons were examined by Dr. Kumatori, ef al. at the Yaizu City Hospital as
outpatients.
The period of hospitalization was 3-6 days.
The 1964 survey was performed from the end
of January and finished at the beginning of
May. During this period, Dr. R. A. Conard from
Brookhaven National Laboratory, the Head of
U.S.A.E.C. Medical Survey Team on Marshallese exposed to fallout on 1 March
1954,
visited Japan to be on hand for the examinations
of Japanese fishermen. Dr. T. Kumatori, National
Institute of Radiological Sciences, went to the
Marshall Islands with Dr. Conard, and cooperated with U.S. Medical Survey Team for about
3 weeks. This exchange visit was valuable for
understanding of radiation effects on both Japanese and Marshallese exposed people.
Physical Examinations
The routine physical examinations revealed
the following:
In 10 cases among the 18 examined, livers were
palpable 4-2 finger breadth below r. costal margin
at mid-clavicular line, but they were soft and
not cirrhotic.
Case K-8 developed r. pulmonary phthisis in
1955 and received chemotherapy. At present,
only small fibrotic foci are observed in r. subcla-
vicular area on chest X-ray film.
Systolic murmurs were heard at the apex of
heart in K-10, and r. bundle-branch block was
proved by ECG.
No medical treatment was
required.
Case T-7 was proved glucosuria. Detailed
medical examinations are to be done at Yaizu
City Hospital.
Cases T-2, K-l, and K~-6 showed slightly
elevated
minimum
blood pressure
(94, 98, 98,
respectively).
C. Skin Lesions
Residual skin changes in areas previously exhibiting beta burns were still observed in some
cases,
Most remarkable residual changes were shown
in abdominal wall (T-6, K-2,4,5, 7, 11, 12, 13).
Pigmentation, depigmentation and teleangiectasia
were observed macroscopically (Plate 1). His-
