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 $(p<0.05)$. 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.

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.
