To establish a difference of the relative contents (RCs) of elements among the cervical, thoracic, and lumbar intervertebral disks and its age-related change, the intervertebral disks between the axis and the sacrum, which were resected from the nine cadavers who died at 53 to 99 yr old, were analyzed by inductively coupled atomic plasma emission spectrometry. It was found that both the RCs of calcium and phosphorus were high in the cervical disks, especially the highest in the disk between the 6th and 7th cervical vertebrae, and lower in the order of the cervical, thoracic, and lumbar intervertebral disks. In regard to the RCs of sulfur and magnesium, there were no significant differences among the cervical, thoracic, and lumbar intervertebral disks. In addition, it was found that both the RCs of calcium and phosphorus in the cervical intervertebral disks started to increase in the sixth decade of life, became the highest in the eighth decade of life, and then decreased.
为确定颈椎、胸椎和腰椎间盘元素相对含量（RCs）的差异及其与年龄相关的变化，对9具年龄在53至99岁之间死亡的尸体中，从枢椎至骶椎之间切除的椎间盘，采用电感耦合原子等离子体发射光谱法进行分析。结果发现，颈椎间盘钙和磷的相对含量均较高，尤其是第6和第7颈椎之间的椎间盘最高，按颈椎、胸椎和腰椎间盘的顺序依次降低。关于硫和镁的相对含量，颈椎、胸椎和腰椎间盘之间无显著差异。此外，还发现颈椎间盘钙和磷的相对含量在生命的第六个十年开始增加，在第八个十年达到最高，然后下降。
