Abstract

This study was aimed at evaluating the effect of red-yeast-rice supplementation on cholesterol-lowering and glucose control in subjects with impaired fasting glucose (IFT) or impaired glucose tolerance (IGT). We conducted a doubleblind, placebo-controlled study with 3 groups; placebo, low dose group (red yeast rice 210.0mg/capsule, 2.52g/day) and high dose group (red yeast rice 420.0mg/capsule, 5.04g/day), which were randomly assigned to subjects with impaired fasting glucose or impaired glucose tolerance. We measured fasting serum concentrations of total-, LDL-, HDL-cholesterol, triglyceride, glucose, insulin, free fatty acid (FFA) and 2 h oral glucose tolerence test (OGTT) before and after the supplementation. Both low dose and high dose groups had significant decrease in LDL cholesterol and atherogenic index (AI) compared with placebo group (p<0.05). Additionally, total and HDL cholesterol improved significantly in high dose group compared with placebo group (p<0.05). Fasting serum glucose decreased in test groups and increased in placebo group after intervention. However, it was not significant differences. In subjects which fasting blood glucose is more than 110mg/dL, fasting glucose had a tendency to decrease in high dose group (p<0.1) and Hemoglobin A1c (HbA1c) had significant decrease in low dose group (p<0.05), while insulin and HOMA-IR had a tendency to increase in placebo group after intervention. Mean changes of glucose related parameters (fasting glucose, insulin, HOMA-IR) compared with placebo group did not show significant differences. In conclusion, subjects with impaired fasting glucose or impaired glucose tolerance were significantly improved in serum lipid profile by red yeast rice supplementation without serious side effects. These are more effective in the case of a high dose. The effects of red yeast rice supplementation on glucose control were insignificant.

내당능 장애와 공복혈당장애는 장차 당뇨병으로 진행되거나 심혈관 질환을 일으키는 위험인자로 간주되어 적절한 혈당 및 혈중지질수치의 조절이 필요하다. 홍국의 기능성분인 모나콜린-K는 stalin계열 약물의 주원료로서 이미 지질 강하제로 잘 알려져 있다. 홍국의 지질 강하제 이외의 다른 효과로서 동물 자체 효력 시험과 문헌 고찰을 통해 혈당 강하 효과가 보고되고 있으므로 이중 맹검, 무작위배정, 위약 대조 인체시험을 통하여 홍국의 혈중 지질 및 혈당 개선에 대한 효능을 확인하는 목적으로 본 연구를 실시하였다. $18{\sim}80$세 사이의 남녀를 대상으로, 스크리닝 시 공복혈당이 110 mg/dl이상 126 mg/dl 이하인 공복 혈당 장애이거나 경구 당 부하 검사 2시간 후 혈당이 140 mg/dl 이상 199 mg/dl 이하인 내당능 장애자이거나 당화혈색소 수치가 6% 이상 7% 이하인 자로서 심각한 합병증이 없는 사람을 대상으로 하였으며, 홍국 저용량군 21명, 고용량군 23명, 위약군 20명으로 총 64명을 대상으로 12주간 검사에 대한 결과분석을 실시하였다. 1차 유효성 지표로 혈중 지질관련 지표인 중성지방, 총 콜레스테롤, LDL 콜레스테롤, HDL 콜레스테롤, Atherogenic index (AI)를 측정하였으며, 2차 유효성 지표로 혈당 지표인 공복 혈당, 경구 당부하 검사 2시간 혈당치, 당화혈색소, 인슐린, MOHAIR, 유리지방산을 측정하였다. 시험군에서 홍국제제 섭취 전후로 중성지방, 총 콜레스테롤, LDL 콜레스테롤, HDL콜레스테롤 수치가 유의적으로 개선되었으며 동맥경화지수도 유의적으로 향상되었다. 홍국 고용량군의 총 콜레스테롤, HDL 콜레스테롤과 LDL 콜레스테롤 및 동맥경화지수 개선 정도는 위약군의 변화량과 비교하여 유의적으로 개선되는 것으로 나타났고, 저용량군의 경우에도 LDL 콜레스테롤과 동맥경화지수 개선 정도가 위약군의 변화량과 비교하여 유의적으로 개선되었다. 홍국의 섭취가 혈당조절에 미치는 영향은 모든 시험군에서 제제 섭취 12주 후 공복혈당이 감소하였고, 시험군이 위약군에 비해 더욱 감소하였으나 통계적으로는 유의하지 않았다. 주평가지표인 공복혈당을 기준으로 공복혈당 110mg/dl 이상인 피험자만을 대상으로 당대사 관련 지표를 분석한 결과, 홍국 고용량군에서 공복혈당의 감소경향이 관찰되었고, 홍국 저용량군에서는 당화혈색소의 유의적인 감소효과를 확인하였으나 위약군의 변화량과 비교하여 유의적이지 않았다. 공복혈당 장애자 또는 내당능 장애자에서 하루 홍국 분말 2.52 g (저용량군) 또는 5.04 g (고용량군)을 포함한 건강기능식품을 12주간 섭취시킨 결과 혈중 지질 농도와 동맥경화 지수의 개선으로 심혈관 질환의 위험도를 낮출 수 있을 것으로 보이며, 고용량군일 경우 더 효과적일 것으로 사료된다.
