폐경여성의 동물모델에서 비만개선에 대한 제니스테인의 농도 의존적인 영향 = Dose-dependent effects of genistein on the improvement of obesity in a mouse model of postmenopausal women

국문 초록 (Abstract)

폐경은 여성비만의 중요한 원인이다. 본 연구는 폐경여성의 동물모델인 난소절제 암컷 쥐에서 몸무게와 혈청 속 지질 성분의 조절에 대한 제니스테인의 농도 의존적 영향을 수영운동과 비교함으로써, 비만 조절에 대한 제니스테인의 효과적인 농도를 조사하였다. 난소절제 암컷 쥐는 대조군, 수영 운동군, 제니스테인 농도별(0.005%, 0.05%, 0.1% wt/wt) 처리군으로 나누고, 모든 쥐는 고지방식 사료를 8주 동안 섭취하였 다. 고지방식 사료를 섭취한 대조군에 비해 수영운동을 실시한 군과 제니스테인이 농도별로 처리된 군 모두 몸무게, 백색지방조직의 무게, 혈청 속 지질 성분 농도 및 간조직의 지질 성분 축적이 감소되었다. 이러한 몸무게, 백색지방조직의 무게, 혈청 속 지질 성분 농도 및 간조직의 지질 성분 축적에 대한 제니스테인의 감소효과는 제니스테인 처리농도에 의존적이었고 제니스테인 농도 0.1%에서 가장 효과적이었으며 1시간 수영운동을 실시한 경우와 유사한 효과를 나타내었다. 본 연구결과들은 난소가 절제된 암컷 쥐에서 적정농도의 제니스테인 처리는 비만개선에 대해 수영운동과 유사한 효과를 나타낸다는 것을 제시한다. 제니스테인 보충제 식이의 섭취는 페경기 여성의 비만예방에 도움을 줄 것이다.
