Abstract
weights of various organs, such as, brain, thymus,
kidney, adrenal gland, thyroid gland, liver, pancreas,
heart, lung, spleen, testis, and ovary, to the body
weights of their own have been summarized from the
460 Korean fetuses of stillborn.
The parameters of each organ are further subdivided according to the sex and the sides with successive
increase of the fetal age, from the 4th until the term
of the fetal life.
1) In contrast to the body weight, the weight of the
brain shows a rapid growth rate in the period from
the 4th to the 6th, whereas the slow in the rest of
the period of the fetal life until term. The brain
weight at the term was reached to about 40 times of
that of the 4th fetal month.
2) The rate of the weight growth of the thymus in
contrast to that of the body weight was relatively higher
during the period from 4th until 8th fetal month than
that of the rest of the fetal period. The weight of
the thymus at term was reached to about 180 times of
the 4th fetal month.
3) The rate from the kidney shows higher in the
period from 4th to 6th, then, was relatively steady
during the rest of the fetal period. The weight of the
10th was reached to about 50 times of that of the 4th
month.
4) The rate of the weight growth of the adrenal
gland was somewhat lower than that of the body weight
throughout the fetal period. The weight of the 10th was
reached 20 times of the 4th fetal month.
5) A low growth rate in the thyroid weight in contrast
to that of the body weight was lower during the period
from 4th to 7th, and was higher during the rest of the
fetal life. The weight of the term was reached at 15
times of that of the 4th month.
6) Of the liver, the higher rate was maintained until
6th, after that the rate became lower in contrast to
that of the body weight. The weight of the 10th was
reached to about 40 times of that of the 4th fetal month.
7) The lower rate from the pancreas before 8th was
contrasted to the higher in the rest of the fetal life.
The weight of the term was reached at about 30 times
of that of the 4th fetal month.
8) The weight of the heart at 10th month was reached
at about 30 times of that of the 4th month, the rate
of the growth, however, was lower than that of the
body weight throughout the period of the fetal life.
9) A similar rate to the heart was also found in the
lung, except the increase of the weight of the term
which was 15 times of that of the 4th month.
10) Until the 8th month, the rate of the spleen was
higher than that of the rest, in which the lower rate was observed. The weight of the term was reached to
about 40 times of that of the 4th fetal month.
11) Of the testis and ovary, as the gonad, somewhat
higher rate was continued until 6th month, then the rate
remains steady during the rest of the fetal life. The
weight of the term was reached to about 10 times of
that of the 4th.
12) None of the statistically significant difference on
the weights of the kidney, adranal gland, testis and
ovary was calculated in present observation.
13) The right lung was heavier than the left.
14) In general, none of the significant weight
difference between Korean and Japanese. The weights
however, were less than those of the European.
