利用氧化亚氮 /乙炔焰原子吸收波谱法 ,对年龄范围在 35～ 97岁之间 1 1 2例 (男 41例 ,女 71例 )骨质疏松或非骨质疏松性骨折手术修复的不同骨组织锶和钙含量进行了测定。钙锶均数分别是 ( 2 5 3.4± 1 1 4.0 ) mg/g和 ( 32 .98± 1 4.91 )μg/g,测定值范围分别在 1 0 0～ 65 0 .0mg/g和 1 6.0 0～ 81 .0 0μg/g之间。男女钙锶两元素的变异系数均大于 40 % ,说明数据的离散程度较大。利用 SAS软件分别计算年龄、性别、骨类型及病理学与元素含量之间的相关性、锶钙比值 ( Sr/Ca)。尽管很多妇女的矿物水平较低 ,但研究表明两元素在两性之间有相似的变化。对于 5 5岁以后的男性和 45岁后的女性来说 ,两种元素含量都有明显降低。尽管两性的元素含量之间有明显差异 ,但还没有证据表明其病理改变依赖于年龄和性别的变化。股骨头矿物质含量低于其它类型骨骼 ,很显然骨的去矿化更容易发生在形成股骨的骨质
Using nitrous oxide / acetylene flame atomic absorption spectrometry, 112 cases (41 males and 71 females) of age ranged from 35 to 97 years old were treated with osteoporosis or non-osteoporotic fracture Tissue strontium and calcium content were determined. The average calcium-strontium concentrations were (2 5 3.4 ± 1 1 4.0) mg / g and (32.98 ± 1.491) μg / g, respectively. The range of values was between 100 and 65 0. ~ 81 .0 0μg / g between. The coefficient of variation of calcium, strontium and bilirubin in both men and women were more than 40%, indicating that the data was more discrete. SAS software was used to calculate the age, sex, bone type and pathological correlation with elemental content, strontium calcium ratio (Sr / Ca). Although many women have low levels of minerals, studies show that there are similar changes in the two elements between the sexes. For men after age 5 and women after age 45, there is a significant reduction in both elements. Despite significant differences between the two elements, there is no evidence that their pathological changes depend on age and gender changes. Femoral head mineral content is lower than other types of bones, it is clear that bone demineralization occurs more easily in the formation of femur bone
