초록

본 실험은 고지방식이로 유발된 비만마우스에서 산마늘 잎 메탄올 추출물의 항비만 효과를 알아보고자 체중변화, 사료섭취량변화, 렙틴과 아디포넥틴 수치변화, 난소주위 지방무게 변화 측정과 지방세포의 조직병리학적 검사를 실시하였으며, 메트포민을 체중당 250 mg 투여한 약물대조군과 비교평가 하였다. 비만유발을 위하여 고지방식이를 13주간 공급하였으며, 고지방식이 공급 7일째에 증류수(비만대조군), 메트포민(약물대조군), 산마늘 잎 메탄올 추출물을 투여하였다. 비만대조군은 확연한 비만이 유발되었으며, 산마늘 잎 메탄올 추출물(62.5, 125, 250 mg/kg) 투여군에서는 이러한 비만이 유의적으로 감소하였다. 결론적으로 산마늘 잎 메탄올 추출물은 비만유발 마우스에서 비만개선작용을 나타내었으며, 나아가 인체에서도 유의한 비만개선작용을 할 것으로 생각된다.

The antiobese effects of Allium victorialis (AV) leaf methanol extract were evaluated in a high fat diet (HFD) supplied mice. The changes on the body weight, food consumption, leptin and adiponectin levels as well as the periovarian fat weights and histopathology of adipocytes were examined. The effects were compared with those of a group given 250 mg/kg of metformin. After 91 days of a continuous HFD supply, the mice were significantly showed obesity. However, the obesity induced by the HFD was inhibited by the AV extract treatment at the three different doses (62.5, 125 and 250 mg/kg) respectively. The results suggest that the AV methanol extract is beneficial for improving the diet-induced obesity in humans.
