Abstract: | It is known that a large quantity of magnesium contains bones, and the magnesium contents in spongy bones decrease gradually
with advancing age. To elucidate the relationships between a decrease of mineral contents in human bones and an accumulation
of minerals in the other human tissues, the content of magnesium was analyzed by inductively coupled plasma-atomic emission
spectrometry among human bones, arteries, veins, and cartilages in 27 subjects (17 men and 10 women). These were resected
from the subjects who died in the age range 40–98 yr. Calcanei were chosen for analysis of magnesium contents in contrast
with femoral, popliteal, and common carotid arteries, internal jugular and femoral veins, superior and inferior venae cavae,
and pubic symphyses.
The magnesium contents in the calcanei decreased gradually with aging, whereas they increased progressively in the arteries,
veins, and pubic symphyses with aging. It was found that as the magnesium contents decreased in the calcanei, they increased
in the arteries, such as the femoral, popliteal, and common carotid arteries, whereas they decreased inversely in the veins,
such as the internal jugular and femoral veins and superior and inferior venae cavae. Furthermore, as the magnesium contents
decreased in the calcanei, they hardly changed in the pubic symphyses. These suggest that magnesium released from bones is
accompanied by accumulation of magnesium in the arteries. |
