Abstract

To elucidate age-related changes of mineral contents in human bones, element contents of human vertebrae and auditory ossicles were determined by inductively coupled plasma atomic-emission spectrometry. The cervical, thoracic, and lumbar vertebrae were removed from 12 vertebral columns. The mallei of auditory ossicle were removed from 27 cadavers. It was found that average relative contents (RCs) of calcium and phosphorus in cervical, thoracic, and lumbar vertebrae remained almost constant within ages ranging from 46 to 99 y. In addition, it was found that the RCs of calcium and phosphorus in men's and women's mallei remained constant within ages ranging from 40 to 98 yr. These results support the view that there is no significant age-dependent change of mineral contents in human bones.

摘要

为了阐明人类骨骼中矿物质含量与年龄相关的变化，采用电感耦合等离子体原子发射光谱法测定了人类椎骨和听小骨的元素含量。从12个脊柱中取出颈椎、胸椎和腰椎。从27具尸体上取出听小骨的锤骨。研究发现，在46至99岁的年龄范围内，颈椎、胸椎和腰椎中钙和磷的平均相对含量（RCs）几乎保持不变。此外，研究发现，在40至98岁的年龄范围内，男性和女性锤骨中钙和磷的RCs保持不变。这些结果支持了这样一种观点，即人类骨骼中矿物质含量没有明显的年龄依赖性变化。
