title: A possible balance of calcium accumulations among bone, cartilage, artery, and vein in single human individuals.
abstract: To elucidate the relationships between the decrease of mineral contents in human bones and the accumulation of minerals in the other human tissues, the relative contents (RCs) of calcium were 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 subjects who died in the age range from 40 to 98 yr old. Calcanei were chosen for analysis of mineral contents in contrast with femoral, popliteal and common carotid arteries, internal jugular veins, and pubic symphysis. It was found that the RCs of calcium in calcanei were agreeable to association with those in both the pubic symphysis and the femoral artery, but they were not agreeable to association with those in the popliteal and common carotid arteries, and the internal jugular veins. This suggests that calcium released from bones is accompanied by accumulations of calcium in the artery and cartilage.
