초록

여성은 폐경 시 음식물 섭취가 증가하여 체중이 증가되고, 정상 여성보다 혈류관련질환 발병이 높아진다. 이에 본 연구에서는 갱년기 장애시 유발되는 체내 지질 함량 증가에 있어 오디 추출물이 미치는 영향을 조사하기 위해 인위적 폐경을 유발시킨 난소절제 횐쥐에 오디추출물을 투여하여 그에 따른 혈 중 효소 활성 및 지질 함량에 미치는 영향을 검토하였다. 그 결과 난소 절제 후 오디추출물 투여는 난소절제로 인해 야기되는 혈 중 total- cholesterol 함량 및 혈청 지질농도의 증가를 감소하였다. 하지만 HDL-cholesterol은 난소절제 군에 비해 난소절제 후 오디추출물을 투여할 경우 그 수치가 증가하였으며, LDL-cholesterol은 반대로 감소하는 것을 볼 수 있어 오디추출물이 갱년기 장애 시 발생할 수 있는 혈 중 지질함량 변화에 효과가 있는 것으로 나타나 혈류관련질환에 대한 개선 식품으로의 활용이 기대된다.

The aim of this study was to evaluate the effects of three different mulberry cultivars extracts on serum lipid contents in ovariectomized estrogen-deficient rats. Sprague-Dawley female rats were randomly assigned to the following groups: sham-operated rats (sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with $ 80\% $ ethyl alcohol extracts from various kinds of Tajikistan mulberry (OVX-TM), Korea mulberry (OVX-KM) and China mulberry (OVX-CM) at 200mg/kg bw/day, respectively. The mulberry extracts were orally administrated at 1mL per day. The body weights of OVX rats were significantly heavier than the sham-operated rats at all values (p <0.05). The ovariectomy caused an expected increasing in the levels of serum total cholesterol and triglyceride. The serum HDL-cholesterol level on the OVX-TM, OVX-KM and OVX-CM groups were higher than in the OVX-control group.
