Abstract

Effects of liquefied calcium supplement on bone mineral density (BMD) and bone health index (osteocalcin, deoxypyridinoline) were investigated in 12 middle aged women. Middle aged women were arranged into 3 groups such as control, Ca500 and Ca750 by liquefied calcium supplement level. BMD was measured at the spine (vertebrae L2-L4). After 6 month, BMD of control group dropped but that of Ca750 were increased from 0.850 to 0.865. The increase in serum calcium and osteocalcin level, and the decrease in urine deoxypyridinoline level were observed in by calcium supplement groups. The bone health index of serum was changed as much as level of calcium supplement. The serum osteocalcin level of Ca750 significantly increased to 7.93 ng/mL after 6 months of calcium supplement. Although we didn't get any significant difference in BMD, we found that the liquefied calcium had no side effect and led effective change in bone health index. Hereafter, we suppose that the liquefied calcium will be available to develop healthy products for preventing osteoporosis.

액상칼슘을 첨가한 한방 칼슘제를 중년여성에게 칼슘제 섭취 수준에 따라 3개의 그룹(대조군, Ca500, Ca750)으로 구분하여 일정 기간 섭취시키고, 이들의 골밀도 및 골형성 지표의 변화에 대해 조사하였다. 6개월 후 대조군의 골밀도가 감소한 반면, Ca750군의 요추 골밀도는 초기값 0.850에서 0.865로 증가하였다. 또한 혈청 칼슘과 혈청 osteocalcin의 증가 및 요중 deoxypyridinoline의 감소는 액상칼슘 첨가 수준이 높을수록 섭취 전후 차이가 뚜렷하였다. 특히 Ca750군에서는 혈청 osteocalcin함량이 초기 5.50 ng/mL에서 칼슘제 섭취 후 7.93 ng/mL로 유의적인 증가를 나타내었다. 전반적인 연구 결과에서 액상칼슘 섭취에 의한 유의적인 골밀도 증가는 확인되지 않았으나, 칼슘제 섭취에 따른 위장장애나 변비등의 부작용이 없고 골형성 표지성분의 증가 및 골흡수 표지성분의 감소를 나타내어, 장기적인 연구가 요망된다.
