Abstract

The suprarenal glands of the 277( (') 155. 우 122) Korean fetuses older than four month of the fetal age were measured biometrically and the results obtained are summarized as follows. 1. As to the three linear measurements of the suprarenals , the length was the longest and the thickness was the smallest. The three linear measurements; length, width and thickness increased gradually as the fetal age increased, and there were no sexual differences. There were stastical differences in the length of the suprarenals between both sides and the left one was longer than the right one after 6th month of fetal period. 2. The depth of the renal surface increased regularly with the progress of developmental fetal period and had stastical differences between both sides after 5th month of fetal age and the left one was deeper than the right one , without sexual differences. 3. The weight of the suprarenals increased slowly up to the 7th month, rapidly up to the 8th month and after that more rapidly. There were stastical differences in weight of the suprarenals between both sides after 6th month of fetal age , but no sexual differences. 4. The relative weight of the suprarenals decreased gradually with the progress of developmental fetal period.
