초록

폐경과 더불어 시작되는 폐경기의 에스트로겐 변화로 발생되는 건강 문제 중 심혈관계질환이 문제점으로 대두되고 있다. 그러므로 본 연구는 갱년기 장애 시 유발되는 체내 지질 함량 증가에 있어서 김 추출물이 미치는 영향을 조사하기 위해 인위적 폐경을 유발시킬 수 있는 난소 절제 쥐에서 김 추출물의 혈 중 지질 함량 변화에 미치는 영향을 검토하였다. 그 결과 난소 절제에 의한 total-cholesterol의 증가가 김 추출물을 투여함으로써 감소하는 경향을 보였다. 특히 김 추출물 50 mg/kg bw/day에서 유의적으로 감소하였다. 혈 중성 지방에서는 김 추출물 농도별 투여한 OVX-PT50, OVX-PT200 모든 군에서 난소를 절제하지 않은 Sham군과 비슷한 수준으로 감소하는 경향을 보였고, 또한 혈 중 HDL-cholesterol은 김 추출물 투여로 인해 난소 절제한 군과 비교해서 높은 경향을 나타내었다. 이상의 결과는 갱년기 장애 시 유발되는 지질 대사 이상으로 오는 심혈관계질환에 김의 섭취가 유익한 결과를 줄 것으로 사료되며, 또한 잘못된 식습관으로 오는 비만이나 심혈관계 질환에도 유익한 효과를 가져다 줄 것으로 기대된다.

The aim of this study is to evaluate the effect of Porphyra tenera (PT) extract on serum lipids content in ovariectomized rats. From day 3 until 42 after the ovariectomy, Sprague-Dawley female rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovarjectomized rats supplemented with PT at 50 mg/kg bw/day (OVX-PT50), 200 mg/kg bw/day (OVX-PT200). The PT ethanol extract were orally administrated at 1 m1 per day. Body weight gain, food intake and food efficiency ratio were not significantly different between groups. Although total-cholesterol was increased in OVX-control, supplementation with the PT decreased the level of cholesterol in serum. Especially, it was significantly decreased in OVX-PI50 (p＜0.05). Triglyceride was significantly decreased to almost all of groups supplemented with PT (p＜0.05). The levels of HDL-cholesterol was higher in PT extract group than OVX-control. These results suggest that supplementation with the PT extract positively influenced on lipid concentration in serum. Consequently, we expect that PT extract decrease risk of cardiovascular diseases by postmenopausal.
