对288例绝经后的妇女,年龄在41—71岁,并在两年内参与钙补充试验,作了理想体重的百分率(％IBW)血清雌激素水平和骨无机物密度的变化(△BMD)及骨无机物含量的变化(△BMC)的相互关系研究。用双光子吸收比色计测量脊柱(L_2—L_4)和股骨颈,用单光子吸收比色计测量桡骨,并排除患者的主动脉钙化及腰椎骨赘。BMD和BMC的变化率的计算是在研究开始以及钙补充治疗后一年及二年。然后进行分析。血清雌激素和雌二醇的浓度在首次就测定,用放射免疫重复分析雌二醇,并对263
Of 288 postmenopausal women aged 41-71 years, who participated in the calcium supplement test within two years, the serum levels of estrogen and bone mineral density (Δ BMD) were calculated as% of ideal body weight (% IBW) and Changes of bone mineral content (△ BMC) correlation study. The spine (L_2-L_4) and the femoral neck were measured with a two-photon absorption colorimeter. The radius was measured with a single-photon absorption colorimeter and exclusion of aortic calcification and lumbar osteophyte. The rates of change of BMD and BMC were calculated at the beginning of the study and one year and two years after calcium supplementation. Then analyze. Serum estradiol and estradiol concentrations were measured for the first time, and estradiol was repeatedly assayed by radioimmunoassay, and 263
