Abstract

This research was performed to investigate the effect of Agarum cribrosum ethanol extracts on the levels of lipids in the serum of rats fed a high-fat diet for 10 weeks. Experimental groups were divided into basal diet only (BDG), high fat diet control (HFDCG), high-fat diet and 5% Agarum cribrosum ethanol extract powder (HF5S), and high-fat diet and 10% Agarum cribrosum ethanol extract powder(HF10S) groups. The levels of hematological variables were not significantly different among the four groups. Compared with the control group's serum total cholesterol level of 89.14 mg/dL, the levels of the HF5S and HF10S groups were significantly lowered to 77.26 and 75.47 mg/dL, respectively. Compared with the control group's LDL-cholesterol leve of 27.41 mg/dL, the LDL-cholesterol levels of the HF5S and HF10S groups were significantly lowered to 20.64 and 20.17 mg/dL, respectively. Also, compared to the control group's serum triglyceride level of 98.36 mg/dL, the triglyceride levels of the HF5S and HF10S groups were significantly lowered to 87.94 and 87.39 mg/dL, respectively. These results indicate that dietary intake of Agarum cribrosum ethanol extracts might have beneficial effects on obesity by reducing body weight and improving blood lipid profile.

고지방식이로 비만 및 고지혈이 유발된 실험동물에서 체중, 혈중지질, 혈청생화학적 검사 및 장기무게를 측정하여 구멍쇠 미역 추출물 투여로 인한 혈중지질 개선효과와 구멍쇠 미역 추출물의 간과 신장의 기능 및 장기무게에 미치는 영향에 대해 조사하였다. 체중 및 사료이용효율은 고지방식이에 의해 고지방군에서 증가현상을 보였으며, 구멍쇠 미역 추출물 5 %와 10 % 투여군인 HF5S과 HF10S군에서 구멍쇠 미역 추출물 투여로 인한 체중증가량 감소와 식이효율 감소현상을 보였다. 혈청 생화학적 검사에서 고지방식이에 의해 혈중 ALT, AST의 증가가 관찰되었으나 구멍쇠 미역 추출물 투여에 의해 기본식이군과 비슷한 수준으로 유지되는 것을 볼 수 있었다. 혈중 creatinine은 고지방식이 및 구멍쇠 미역 추출물 투여에 영향을 받지 않았으나 g-GT의 경우 구멍쇠미역 추출물을 10 % 첨가하였을 때는 유의적으로 감소하여 기본식이군과 고지방식이군보다 낮아졌다. 혈중지질 변화는 총 콜레스테롤, LDL-콜레스테롤, triglyceride, 동맥경화지수(AI) 모두 고지방식이에 의해 유의적인 증가현상을 보였으며, 구멍쇠 미역추출물 투여한 경우 고지방식이군에 비하여 총콜레스테롤과 LDL-콜레스테롤은 감소하였으나 동맥경화지수는 변화가 없었다. 이상의 실험결과 구멍쇠 미역 추출물은 비만유도 흰쥐에서 체중과 간의 무게 감소와 더불어 혈청의 지질성상의 개선에 긍정적인 영향을 미치는 것으로 나타났다. 이러한 결과는 구멍쇠 미역에 함유된 다량의 식이섬유소와 미네랄 등의 생리활성 물질이 지질대사를 개선시키고 지방 축적을 억제하여 비만, 고지혈증, 이상지혈증의 예방 및 개선 효과를 나타낼 것으로 기대되며 나아가 심혈관계 질환의 예방 및 치료에 긍정적인 효과가 있을 것으로 사료된다.
