초록

곤약 글루코만난(liquid konjac)을 동결건조한 식빵에 첨가한 사료를 고지방식이로 유도한 비만 흰쥐에 6주간 급여하였을 때의 체중, 혈청지질, 비만지수에 미치는 영향을 조사하였다. 실험군은 정상군(NC), 고지방식이 비만 대조군(HF), 고지방식이 비만+곤약 글루코만난을 10% 되게 혼합하여 동결건조 한 식빵을 사료에 10% 혼합한 식이군(KGM1) 및 비만+곤약 글루코만난을 20%되게 혼합하여 동결건조한 식빵을 사료에 20% 혼합한 식이군(KGM2)으로 구분(군당 7마리)하여 6주간 사육하였다. KGM1군과 KGM2군은 HF군에 비하여 혈청 중성지질, 총지질, 총콜레스테롤, LDL-콜레스테롤 함량 및 atherogenic index(AI)는 감소하였으나 HDL-콜레스테롤 함량은 증가하였다. KGM1군과 KGM2군은 HF군의 체중에 비하여 감소하였으며 곤약 글루코만난 첨가 식빵의 비율이 높아질수록 체중감소율이 높았다. 체지방 함량은 NC군 및 HF군에서는 실험식이 6주후에 크게 증가하였으나 KGM1군은 유의적인 변화가 없었고, KGM2군은 감소하였다. 따라서 곤약 글루코만난 첨가 식빵은 고지방식이로 유도된 비만 흰쥐에서 체지방 함량을 감소시키는 효과가 있었다.

The effects of white bread supplemented with konjac glucomannan on diet-induced obesity in rats were investigated. Four groups of male Sprague-Dawley rats were examined: a non-obese control group (NC), an obese high fat diet group (HF), an obese high fat diet group given bread supplemented with 10% konjac glucomannan (KGM1) and an obese high fat diet group given bread supplemented with 20% konjac glucomannan (KGM2). The daily weight gain of the KGM1 group increased slightly and decreased in the KGM2 group compared to the HF group. The serum triglycerides, total lipid, total cholesterol, and HDL-cholesterol increased in the HF compared to the NC group, whereas they decreased in KGM1 and KGM2 groups. After having this experimental diet for 6 weeks, the body weight in KGM1 and KGM2 groups decreased compared to the HF group. While the initial R$\ddot{o}$hrer index was 23.13 in the NC group, and 31.50~32.59 in the HF, KGM1, and KGM2 groups, the index after the experimental diets for 6 weeks was 28.39 in the NC group, 36.88 in the HF group, 33.48 in the KGM1 group and 29.64 in the KGM2 group. The level of body fat increased from 1% to 7.14% in the NC group, from 15.60% to 60.05% in the HF group, and from 10.60% to 10.83% in the KMG1 group, but decreased from 10.45% to 8.20% in the KGM2 group. These results demonstrate that white bread with glucomannan is effective in reducing body weight and serum lipids in high fat diet-induced obese rats.
