Abstract

Osteoporosis is one of the major health problem affecting postmenopausal women. Estrogen deficiency results in an increase in bone turnover, lead to bone resorption and an increase risk of fracture. The aim of this study was to evaluate the effects of Capsosiphon fulvecense extract (SCF) on the collagen content of the connective tissues and alkaline phosphatase activity of serum in ovariectomized estrogen-deficient rats. Three groups were surgically ovariectomized (OVX). The fourth group was sham operated. Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with CsF at 50mg/kg body wt (OVX-CSF50) and ovariectomized rats supplemented with CsF at 200mg/kg body wt (OVX-CSF200). The Capsosiphon fulvecense extracts were orally administrated at 1mL per day. The ovariectomy caused a decreasing in the levels of collagen content in bone, cartilage, skin and lung tissues. However CSF groups, supplementation with Capsosiphon fulvecense extract, were increased the level of collagen content in bone, cartilage, skin and lung tissues than OVX-control group. Alkaline phosphatase activity also were increased and calcium levels were decreased than OVX-control on serum. These results suggest that Capsosiphon fulvecense supplementation prevents postmenopausal bone loss, thus it may be used possibly to improve the quality of life in menopausal women.

여성의 폐경에 의한 estrogen의 감소는 골다공증을 유발시킨다고 알려져 있다. 최근 새로운 식품으로 각광받고 있는 매생이 추출물을 인위적 갱년기 장애를 유발시킨 흰쥐에 투여하여 혈 중 ALP활성 변화와 골 중의 collagen의 함량 및 collagen 가교물질 pyridinoline과 deoxypyridinoline 함량 변화를 측정하여 그 효과를 검토해 보았다. 매생이 추출물을 갱년기를 유도한 흰쥐에 투여하여 혈 중 ALP활성 변화에 미치는 영향을 검토한 결과 난소절제에 의하여 ALP활성이 증가하였으나, 매생이 추출물 투여한 군에서 ALP활성이 억제되는 것을 확인할 수 있었다. 또한 난소절제에 의해 연골의 collagen 함량이 감소되었는데, 이는 매생이 추출물을 투여함으로써 정상적인 수치로 증가하는 경향을 나타내어 매생이 추출물이 골 대사와 관련된 골 대사질환에 유효한 효과를 나타낼 것으로 추측된다. 또한 collagen 가교물질로써 골대사의 biomaker인 pyridinoline 및 deoxypyridinoline의 연골 중의 함량은 난소절제에 의해 감소하였고, 매생이 추출물 투여에 의해 증가하여 estrogen부족으로 인한 골 손실에 매생이 추출물이 유익한 효과를 가지는 것으로 보이며, 이는 매생이 중에 함유되어 있는 phytoestrogen에 의한 것으로 추측되어 앞으로 구체적인 검토가 필요한 것으로 사료된다.
