초록

본 연구는 칼슘 급원으로서 $\beta-glucan-egg$ shell calcium complex($\beta-glucan-Ca$ 복합체)의 유효성을 확인하여 칼슘 보충제 개발에 활용하고자 실시하였다. 신령버섯에서 추출한 $\beta-glucan$과 난각의 Ca을 결합시켜 $\beta-glucan-Ca$ 복합체로 제조하여 골다공증 실험동물에서 $\beta-glucan$$\beta-glucan-Ca$ 복합체가 골 대사에 미치는 효과를 비교하였다. 10주령의 Sprague-Dewley 암컷 흰쥐의 양쪽 난소를 절제(OVX)한 후 실험식 이를 급여하였으며 Sham-대조군(Sham-C)은 실험군과 동일한 스트레스를 주기 위해 난소를 절제하지 않고 개복수술만 실시한 후 실험하였다. 식이조성은 Sham-C, OVX-대조군(OVX-C)와 $OVX-\beta-glucan$군(OVX-G)은 $CaCO_3$로 Ca 함량이 0.5%가 되도록 조정하였으며, OYX-G군은 $\beta-glucan$을 첨가하여 제공하였다. $OVX-\beta-glucan-Ca$ 복합체군(OVX-GE)은 $\beta-glucan-Ca$ 복합체의 Ca 농도가 0.5% 함유하도록 조정하여 실험식이를 각각 조제하여 6주간 급여하였다. 체중 100 g당 건조시킨 대퇴골의 무게는 Sham-C>OVX-GE>OVX-C와 OVX-G의 순으로 나타나 $\beta-glucan-Ca$ 복합체를 제공한 OVX-GE에서 다른 OVX군에 비해 상대적으로 골 무게가 증가하는 경향을 보였다. 대퇴골의 골밀도는 각 군 간의 유의적인 차이를 보였으며 Sham-C에 비해 $\beta-glucan$을 첨가한 식이를 제공받은 군에서 골밀도가 상대적으로 높은 수준을 보였고 특히 OVX-GE에서 가장 높은 골밀도를 보였다. Ca체내 흡수율과 보유량은 각 군 간에 유의적인 차이를 보였으며 OVX-C가 Sham-C에 비해 높았으며 OVX군에서는 $\beta-glucan$를 첨가한 군이 높은 수준을 보였다. ALP의 활성은 OVX군에서는 $\beta-glucan$을 첨가한 군이 다소 낮은 경향을 보였다. 요 중의 골 흡수 지표인 DPD crosslink value는 각 군 간의 유의적인 차이를 보였고 OVX군의 DPD crosslink value가 Sham-C에 비해 현저하게 높은 수준으로 나타나 OVX군의 골 흡수가 높음을 확인할 수 있었다. OVX군에서 $\beta-glucan$을 첨가한 식이를 제공한 OVX-G와 OYX-GE의 DPD crosslink value가 OVX-C에 비해 유의적으로 낮은 수준이었으며 $\beta-glucan$이 난소 절제 흰쥐 모델에서 골 대사에 영향을 미쳐 골 흡수율을 낮추어 골 보호효과를 나타내는 것으로 보인다. 이상의 결과들로 미루어 볼 때, 비록 $\beta-glucan$을 제공한 군과 $\beta-glucan-Ca$ 복합체를 제공한 두 군 간에는 유의적인 차이를 보이지 않았으나 난소절제 흰쥐모델의 골 대사에서 $\beta-glucan-Ca$복합체 형태가 골다공증 예방을 위한 기능성 식품으로서의 가능성을 보여주었으며, 앞으로 골다공증 예방을 위한 $\beta-glucan-Ca$ 복합체 형태의 효과적인 농도는 계속적으로 연구가 진행되어야 할 것으로 사료된다.
