Abstract

The relative contents (RCs) of elements in the human menisci from 23 subjects in the age range between 65 and 93 yr were analyzed by inductively coupled plasma atomic emission spectrometry. The RCs of sulfur, calcium, and phosphorus in menisci increased progressively until the 80s, being the highest in the 80s, and thereafter decreased. The RCs of magnesium in menisci increased progressively until the 90s. Regarding the medial and lateral menisci, higher RCs of magnesium and iron, and a lower RC of phosphorus were found in lateral menisci in comparison with those in medial menisci. There were sexual differences in the RCs of calcium and phosphorus of medial and lateral menisci. The RCs of calcium and phosphorus were about 50% higher in women's menisci than in men's. Histological examinations showed that structureless mucoid masses were observed in the menisci, with very high RCs of calcium and phosphorus being detected.

摘要

采用电感耦合等离子体原子发射光谱法分析了23名年龄在65至93岁之间受试者的人半月板中元素的相对含量（RCs）。半月板中硫、钙和磷的相对含量在80岁之前逐渐增加，在80岁时达到最高，此后下降。半月板中镁的相对含量在90岁之前逐渐增加。关于内侧半月板和外侧半月板，与内侧半月板相比，外侧半月板中镁和铁的相对含量较高，而磷的相对含量较低。内侧和外侧半月板钙和磷的相对含量存在性别差异。女性半月板中钙和磷的相对含量比男性高约50%。组织学检查显示，在半月板中观察到无结构的黏液样团块，检测到钙和磷的相对含量非常高。
