摘要
目的 探讨妊娠妇女骨钙代谢及骨密度变化及补钙的影响。 方法 选择正常妇女、未服钙孕晚期妇女及孕晚期服钙妇女各 30例清晨空腹抽血留尿 ,测定胫骨超声速率 ,以骨钙素为骨形成指标 ,尿钙及尿脱氧吡啶啉与肌酐的比值为骨吸收指标 ,并测定血清总钙、游离钙、总蛋白、磷、及镁。 结果 妊娠晚期妇女胫骨 SOS降低明显 ;血清总钙、总蛋白、磷及镁均下降 ,尿钙 /Cr与尿脱氧吡啶啉 /Cr上升明显。服钙组有改善。 结论 妊娠晚期妇女骨形成减少 ,骨吸收增加 ,胫骨 SOS下降。服钙后可部分缓解。
Objective To explore the calcium metabolism in pregnant women. Methods The women were divided into 3 groups: (1) taking calcium (n=30); (2) Normal third trimester (n=30); (3)nonpregnant (n=30). Blood and urine samples were collected at 8:00 a.m. following an overnight fast, in same day tibia SOS was measured by ultrasound scanner. BGP was considered for bone formation markers, and the urinary calcium and Dpy creatinine ratio evaluated for bone absorption markers. Total calcium, free-calcium, phosphorus, magnesium and total protein were measured. Results As compared with normal third trimester tibia SOS in pregnant women declined . BGP, total calcium, phosphoris, magnesium, total protein decreased .The urinary calcium and Dpy creatinine ratio increased. Conclusions As compared with nonpregnant the normal third trimester tibia SOS in pregnant women decreased; bone formation decreased; bone absorption increased.
