Abstract

The effects of dietary fiber isolated from Synurus deltoides on constipation induced by loperamide (4 mg/kg/day) were investigated. Food intake and body weight both decreased in the 5% S. deltoides dietary fiber and loperamide-treated group (SD5) and 10% S. deltoides dietary fiber and loperamide-treated group (SD10), whereas fecal water contents increased by 2.4 and 3.4-fold in the SD5 and SD10 groups, respectively. The concentrations of total-cholesterol, HDL-cholesterol and triglyceride in the sera of the SD5 and SD10 groups were lower than those in the control (C) group. However, the biochemical parameters, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), and glucose levels, were not affected by the level of S. deltoides. In addition, the concentrations of total-cholesterol and triglyceride in the livers of the SD5 and SD10 groups were also significantly lower than those in the control group. These results suggest that dietary fiber isolated from S. deltoides might ameliorate constipation symptoms, and lower lipid concentrations in the blood and liver.

새로운 식이섬유 소재 발굴을 위하여 수리취 식이섬유의 변비 개선 효능을 검정한 결과, 흰쥐의 사료섭취량과 체중 변화는 정상군에 비해 수리취 식이섬유 투여군이 유의적으로 낮아 식욕억제와 비만예방에 효과가 있을 것으로 사료된다. 분변의 수분함량은 수리취 식이섬유 급이 시 식이섬유 첨가량에 따라 각각 2.4배 및 3.4배 증가하였으며, 간과 신장의 무게는 각 군간 차이가 없어 수리취 유래 식이섬유는 10% 농도에서 간과 신장에 독성이 없는 것으로 판단된다. 수리취 식이섬유 10% 급이 시 혈중 total-cholesterol, HDL-cholesterol 및 중성지방은 감소하였으며, 간 조직 내 지질농도는 혈중 지질농도와 마찬가지로 total-cholesterol 및 중성지방은 정상군 및 대조군에 비해 수리취 식이섬유 투여군에서 감소하였고, HDL-cholesterol 농도는 대조군에 비해 높아지는 경향을 보였으나 유의차는 없었다. 이와 같은 결과로 보아 수리취 식이섬유는 식욕을 억제하고 혈중 지질의 농도를 감소시키며 변비의 증상을 개선하는 효과가 있는 것으로 사료된다.
