To elucidate compositional changes of the veins with aging, the authors investigated the relationships among element contents in the internal jugular veins, in which a higher accumulation of calcium and phosphorus occurred with aging. The subjects consisted of 15 men and 10 women, ranging in age from 40 to 98 yr. The element contents of the internal jugular veins were determined by inductively coupled plasma-atomic emission spectrometry. It was found that there were extremely significant direct correlations among the contents of calcium, phosphorus, magnesium, and sodium in the internal jugular vein. In addition, very significant direct correlations were also found both between zinc and either iron or silicon contents and between sulfur and iron contents in the vein. As calcium and phosphorus increased in the internal jugular vein, the mass ratios of Mg/Ca and Mg/P decreased gradually in the vein, whereas the mass ratio of Ca/P hardly decreased. These results indicated that with regard to both the relationships among the contents of calcium, phosphorus, and magnesium and the changes of the mass ratios of Mg/Ca and Mg/P, the internal jugular vein was very similar to the arteries.
为了阐明静脉随年龄增长的成分变化，作者研究了颈内静脉中元素含量之间的关系，其中钙和磷的积累随年龄增长而增加。研究对象包括15名男性和10名女性，年龄在40至98岁之间。通过电感耦合等离子体原子发射光谱法测定颈内静脉的元素含量。结果发现，颈内静脉中钙、磷、镁和钠的含量之间存在极显著的直接相关性。此外，还发现静脉中锌与铁或硅含量之间以及硫与铁含量之间存在非常显著的直接相关性。随着颈内静脉中钙和磷的增加，静脉中Mg/Ca和Mg/P的质量比逐渐降低，而Ca/P的质量比几乎没有降低。这些结果表明，就钙、磷和镁含量之间的关系以及Mg/Ca和Mg/P质量比的变化而言，颈内静脉与动脉非常相似。
