| Abstract: | To elucidate the compositional change of ligaments with aging, the authors investigated both age-related changes of elements
and relationships among elements in the round ligaments of the uterus (round ligaments) by inductively coupled plasma-atomic
emission spectrometry. The bilateral round ligaments were resected from 20 cadavers and also from the uteri removed surgically
from 11 patients bearing uterine myoma or cancer. Thirty-one subjects ranged in age from 34 to 92 yr. It was found that both
S and Mg decreased gradually in the round ligaments with aging, but Ca, P, Zn, Fe, and Al did not change significantly with
aging. Regarding the relationships among elements, very significant direct correlations were found among the contents of Ca,
P, S, and Mg in the round ligaments, whereas significant inverse correlations were found between the contents of Zn and elements,
such as Ca, P, S, and Mg. It should be noted that there was an extremely significant direct correlation between Ca and P contents
in the round ligaments. |
