Abstract

Recently, there has been a marked increase in the use of bioactive products resulting from the fermentation of natural substances by microorganisms. In this study, Opuntia humifusa (OH) was fermented using Lactobacillus plantarum (fermented Opuntia humifusa; fOH). We then examined the anti-obesity effect of fOH in mice fed a 45% Kcal high fat diet (HFD). In this study, mice were treated with fOH concentrations of 100, 200, and 400 mg/kg. The mice in the control group were treated with OH at a concentration of 400 mg/kg based on previous animal experiments. All of the mice given a continuous HFD showed an increase in their weight, the density of abdominal fat, and the accumulated periovaric and abdominal fat. All of these obesity-linked factors, however, were significantly decreased in the groups treated with fOH at concentrations of 200 and 400 mg/kg. Mice treated with fOH at 100 mg/kg did not show a significant decrease in these obesity-linked factors compared to the control group. It appears that fOH fermented by L. plantarum has a greater anti-obesity effect in HFD-supplied mice compared to unfermented OH. While further studies of fOH are needed to examine its effect on obesity, hyperlipidemia, hepatic steatosis, renal function, and type II diabetes with its relevant complications, fOH may have significant therapeutic potential in the treatment of metabolic syndrome.

미생물을 이용한 천연물 발효 시 유용생리활성 증가가 보고된 바, 천년초(Opuntia humifusa; OH)를 Lactobacillus plantarum 을 이용하여 발효시켰으며(fermented Opuntia humifusa; fOH), fOH 의 비만 억제 효과를 확인하기 위해 45%Kcal 고지방식이(HFD)로 비만을 유도하였다. 이 전의 동물실험에 근거하여 OH 400 mg/kg 농도로 처리하였으며, fOH 는 최고 농도 400 mg/kg을 비롯하여 200, 100 mg/kg으로 처리하였다. 지속적인 HFD 공급으로 HFD 대조군에서는 체중, 복부지방 밀도, 난소주위 축적 지방 및 복부 축적 지방량 등이 증가하였으나, fOH 400, 200 mg/kg 처리군에서는 이들 비만인자들이 모두 유의적으로 감소하였다. fOH 100 mg/kg 처리 된 HFD 마우스는 OH 400 mg/kg 처리 마우스에 비해 의미 있는 억제 효과가 나타나지 않았다. 이는 OH에 비해 L. plantarum 로 발효된 fOH가 HFD공급 마우스에서 항비만 효과를 상승시키는 것으로 보인다. 추가적으로 2형 당뇨병 및 관련 합병증으로 확대하여 비만, 고지질혈증, 간지방증, 신장 기능 등을 이용하여 억제 기작 연구가 진행되면 대사증후군을 위한 새로운 강력한 치료제로서의 제안될 가능성이 있다.
