초록

본 연구는 상엽추출물이 포함된 보리면의 혈당조절능력을 입증하기 위하여 4주간 고지방/고탄수화물 식이 후 streptozotocin과 nicotinamide로 당뇨를 유발하고 음성대조군, 양성대조군, 보리면대조군, 상엽대조군, 보리면+상엽추출물 2.5%군, 보리면+상엽추출물 5%군의 6군으로 나누었다. 그 후 2주간 식이를 진행하며 체중, 혈당, 간 기능 및 혈액 내 지질의 변화를 측정하였다. 그 결과 보리면과 상엽 단독 섭취군보다 혼합섭취군에서 체중 감소가 적었고 혈당조절효과도 뛰어났으며 이는 경구 당 부하검사에서도 동일한 결과를 보였다. 또한 간기능, 혈중 지질 개선 효과도 혼합 섭취군에서 강하게 나타났다. 따라서, 보리면과 상엽추출물을 함유한 식이는 복합식이에서 단독식이보다 강한 혈당조절효과와 간 기능 개선, 지질 강하효과도 나타났다. 결과적으로 상엽을 포함하는 보리면은 혈당을 조절하고, 간 기능, 지질 강하 기능을 보여 만성질환 관리에도 도움이 될 것으로 사료된다.

This study aimed to investigate the blood glucose regulatory effect of barley noodles contained mulberry leaves water extract (MLWE) in diabetic mice in order to provide fundamental data as a functional food. ICR mice were divided into six groups as follows: normal control, positive control, barley control, mulberry control, barley+MLWE 2.5% and barley+MLWE 5% groups. High fat/high carbohydrate diet was fed for 4 weeks and diabetes mellitus was induced by i.p. injection of streptozotocin and nicotinamide. After diabetes induction, experimental diet was supplemented for 2 weeks and simultaneous measurement of body weight, blood glucose (including glucose tolerance test), liver function and blood lipid profile was conducted. As a result, there was less decrease in body weight compared to the positive control group in the groups that supplemented barley and MLWE together than the group ingesting barley and MLWE alone. In addition, regulatory effects on blood glucose, liver function and blood lipid concentration were also stronger in barley and MLWE concurrently supplemented groups. Consequently, combination of barley and MLWE was effective in the regulation of body weight, blood glucose, liver function, and blood lipid in diabetic mice. Therefore, this recipe could be a promising strategy for beneficial effects in the patients of diabetes mellitus.
