Abstract

본 연구는 미생물 유래 베타-글루칸의 항비만 효과를 검증하기 위하여 동물실험을 통해 식이 베타-글루칸이 체지방 형성과 혈중 지질에 미치는 영향을 조사하였다. Sprague-Dawley종 흰쥐를 6주간 고지방 식이로 사육하여 비만을 유도한 후 베타-글루칸을 각각 식이 무게의 0%(고지방 대조군), 0.1%, 0.5%로 함유한 식이로 5주간 사육하였다. 정상 대조군은 AIN-76A 식이로 사육하였다. 고지방식이군에서 단위체중당 체지방이 많았으며, 0.1% 베타-글루칸 공급은 고지방 식이에 의해 유도된 복막지방, 내장지방 축적을 각각 16%와 19% 억제하였고, 혈중 렙틴을 28% 감소시켰다(P 【This study was aimed to investigate the effect of dietary ${\beta}$ -glucan obtained from bacterial fermentation on the adiposity and serum lipids level in rats.

For comparison, normal control groups fed AIN-76A diet. Supplemented with 0.1% ${\beta}$ -glucan resulted in a significant reduction of high-fat induced peritoneal fat and visceral fat development by 16%, 19%, and 28%, respectively(P ${\beta}$ -glucan(P ${\beta}$ -glucan reduced adiposity and improved serum lipids in obese rats fed high fat diet. The present study suggest that ${\beta}$ -glucan supplementation to the diet is beneficial in suppressing diet-induced obesity and dyslipidemia.】
