Abstract

폐경을 앞둔 여성에서는 폐경기 증후군, 허혈성 심장질환의 발생빈도증가 등의 문제점을 가지고 있다. 그러므로 해조류 중 톳 추출물을 인위적으로 갱년기 장애를 유도한 흰쥐에 투여하여 혈 중 지질 농도변화에 미치는 영향을 검토하였다. 난소 절제에 의한 estrogen부족이 심혈관계 질환에 영향을 미치는 결과를 초래하는 지질대사에서는 total-cholesterol과 중성지방의 경우 난소절제에 의해 증가된 함량이 톳 추출물을 투여함으로써 감소하는 경향을 보였다. 또한 혈 중 HDL-cholesterol은 톳 추출물 모두 난소절제한 군과 비교해서 유의적 높은 경향을 나타내어 혈중 지질조성 개선에 톳이 유효한 효과를 나타내었다. 본 실험의 결과로부터 갱년기 장애시 유발되는 지질대사 이상으로 오는 심혈관계 질환에 톳 추출물이 유효한 효과를 줄 것으로 사료되며 또한 잘못된 식습관으로 오는 비만에도 유익한 효과를 가져다 줄 것으로 기대된다. The aim of this study was evaluated the effect of biological activity of Hijikia fusiforme (HF). To investigate the effects of biological activity of HF ethanol extracts, Sprague-Dawley female rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented ethanol extracts of HF at 50 mg/kg bw/day (OVX-HF50), ovariectomized rats supplemented ethanol extracts of HF at 200 mg/kg bw/day (OVX-HF200). HF ethanol extracts were orally supplemented at the level of 1 mL per day. The body weight gain, food intake and food efficiency ratio were not significantly different between groups. Although total-cholesterol and triglyceride were increased in the ovariectomized control, supplementation with the HF extracts decreased the levels. And HDL-cholesterol levels were significantly increased after supplementation with the HF extracts <TEX>$(p<0.05)$</TEX>. According to these results, we could known the effects biological activity of Hijikia fusiforme. Consequently, we expect the effects of Hijikia fusiforme extract on cardiovascular diseases aging coming from postmenopausal.
