Increases of calcium and magnesium and decreases of phosphorus and iron with aging in human uterine tubes

To elucidate compositional changes of the uterine tube by aging, the author s studied age-related changes of elements in human uterine tubes by inducti vely coupled plasma-atomic emission spectrometry. The uterine tubes were re sected postmortem or surgically removed from patients with uterine myoma. I t was found that the contents of calcium and magnesium increased progressiv ely with aging in uterine tubes, whereas the contents of phosphorus and iro n decreased gradually with aging. The sulfur content of uterine tubes remai ned constant and independent of aging. Regarding relationships between elements, significant relationships were fo und between calcium and magnesium contents, between phosphorus and iron con tents, between phosphorus and sulfur contents, and between phosphorus and s odium contents in human uterine tubes.
