Abstract

The effect of hemicellulose extracted from soy fiber on the level of blood glucose and serum cholesterol in the streptozotocin-induced diabetic rat were investigated. The experimental plots were divided to cellulose group (control, 0.5％ hemicellulose group (H-l) and 1％ hemicellulose group (H-2) group. The groups were fed for 6 weeks, then fed for 1 week more after streptozotocin injection. Food intakes, weight gain and food efficiency ratio of H-2 group were higher, while water intakes and liver weight were lower than those of control and H-l group. The content of blood glucose and urine glucose were 212.8 mg/dL, 0.97 mg/dL in the control group, 160.5 mg/dL, 0.53 mg/dL in the H-l group, 141.0 mg/dL, 0.35 mg/dL in the H-2 group, respectively. There was no significantly difference in the content of neutral lipid, while the content of total serum cholesterol was 101.6 mg/dL in the control group, 73.8-78.4 mg/dL in the hemicellulose groups. The content of serum HDL-cholesterol in the all experimental groups showed no significantly difference showing 39.8-44.7 mg/dL. HTR and atherogenic index were 0.44 and 1.27 in the control group, but 0.54 and 0.46-0.85 in the hemicellulose groups, respectively.

콩 식이섬유로부터 제조한 헤미셀룰로즈가 streptozotocin으로 유발한 당뇨쥐의 혈당과 혈청콜레스테롤함량에 미치는 영향을 조사하였다. 실험군은 셀룰로즈군(대조군), 헤미셀룰로즈 0.5% 식이군(H-1군), 헤미셀룰로즈 1% 식이군(H-2군)으로 나누어 6주간 사육한 후 당뇨를 유발시키고 계속해서 1주간 사육하였다. 당뇨유발에 따른 식이섭취량과 체중증가량 및 식이효율은 H-2식이군이 대조군과 H-1군에서 보다 높은 값을 나타낸 반면 음용수 섭취량은 H-2군에서 낮았다. 간장의 무게는 H-2군이 대조군과 H-1군에 비하여 유의적으로 낮았다. 혈당은 대조군에서는 212.8 mg/dL, H-1 군에서는 160.5 mg/dL, H-2군에서 는 141.0 mg/dL으로 H-2군은 대조군의 66%수준이었으며 뇨당은 대조군 0.97 mg/dL, H-1군 0.53 mg/dL, H-2군 0.35 mg/dL로 H-1군은 대조군의 55%, H-2군은 대조군의 36%로 헤미셀룰로즈 식 이군이 대조군에 비하여 유의적으로 낮았다. 혈청내 중성지질의 함량은 식이에 따른 유의적 인 차이는 보이지 않았으나 혈청 총콜레스테롤 함량은 대조군에서 101.6 mg/dL, 식이군에서는 73.8∼78.4 mgidL로 유의적으로 낮았으며, 혈청 HDL-콜레스테롤 함량은 모든 실험군에서 39.8∼44.7 mg/dL 범위로 비슷한 수치를 나타내었다. HTR과 동맥경화지수는 대조군에서는 각각 0.44 및 1.27로 나타났으나 헤미셀룰로즈 식이군에서는 각각 0.54 및 0.46∼0.85로 대조군보다 낮았다. 이상의 결과, 콩 식이섬유로부터 추출한 헤미셀룰로즈는 항당뇨효과가 높음을 나타내었다.
