The relative contents (RCs) of elements in the femoral arteries as well as the thoracic aorta, coronary, basilar, and radial arteries from 26 subjects within the age range between 55 and 92 yr old, were analyzed by inductively coupled plasma atomic emission spectrometry. The RCs of calcium and phosphorus in the femoral arteries started to increase before the age of 60 yr. The RCs of magnesium increased after the age of 70 yr. However, the RCs of sulfur did not change significantly within the age range between 55 and 92 yr. With regard to localization of the mineral accumulations in the femoral arterial wall, it was found that the accumulations of calcium and phosphorus occurred only in the tunica media, only in the tunica intima, or in both the tunica media and the tunica intima. The manner of accumulation of calcium and phosphorus in the femoral arterial wall was different from that in the aortic wall. The average RCs of calcium in the 26 specimens were the highest in the femoral artery, followed in descending order by the thoracic aorta, coronary, basilar, and radial arteries. The average RCs of phosphorus were highest in the thoracic aorta, followed by the coronary, femoral, basilar, and radial arteries. It is noted that the accumulation of mineral elements never occurred uniformly in all the arteries.
采用电感耦合等离子体原子发射光谱法，分析了年龄在55至92岁之间的26名受试者股动脉、胸主动脉、冠状动脉、基底动脉和桡动脉中元素的相对含量（RCs）。股动脉中钙和磷的相对含量在60岁之前开始增加。镁的相对含量在70岁之后增加。然而，在55至92岁的年龄范围内，硫的相对含量没有显著变化。关于矿物质在股动脉壁中的沉积位置，发现钙和磷的沉积仅发生在中膜、仅发生在内膜或同时发生在中膜和内膜。钙和磷在股动脉壁中的沉积方式与主动脉壁不同。26个样本中钙的平均相对含量在股动脉中最高，其次依次为胸主动脉、冠状动脉、基底动脉和桡动脉。磷的平均相对含量在胸主动脉中最高，其次为冠状动脉、股动脉、基底动脉和桡动脉。值得注意的是，矿物质元素的沉积在所有动脉中并非均匀发生。
