Abstract

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.

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.
