저항전분 투여가 loperamide 유도 변비 쥐의 체중변화와 배변상태에 미치는 영향

국문 초록 (Abstract)

본 연구는 2종류의 저항전분(RS2, RS3)이 loperamide 유도 변비 쥐의 체중변화와 배변상태에 미치는 영향을 다른 식이섬유 급원과 비교하여 실험 관찰하였다. 실험동물은 Sprague-Dawley계 수컷 쥐 60마리를 사용하였으며 정상 대조군, 변비 셀룰로오스군, 변비 펙틴군, 변비 RS2군, 변비 고RS2군, 변비 RS3군의 6개 군으로 나누었다. AIN-76 기본식이에 각각 다른 식이섬유를 첨가하고 에너지 밀도가 동일하게 조제한 실험식을 5주 동안 투여하여 변비 쥐의 식이효율과 체중 변화 및 배변상태와 장통과시간을 분석 비교하여 다음과 같은 결과를 얻었다. 저항전분 투여군들은 셀룰로오스군에 비해서 식이효율과 체중 증가가 유의적으로 낮았고 펙틴군과는 차이가 없었다. 소장의 길이는 모든 식이섬유군간에 유의적 차이가 없었으나, 대장의 길이는 저항전분군들에서 펙틴군에 비해 유의적으로 길었고, 셀룰로오스군과는 유의적인 차이가 없었다. 사료섭취량 대비 분변 배설량은 저항전분 RS2의 경우는 펙틴군 보다는 높았고 셀룰로오스군 보다는 유의적으로 낮았으나 RS3군은 셀룰로오스군과 유의적인 차이가 없이 많았다. 분변의 외형은 RS3군과 고RS2군은 셀룰로오스군과 유사하였으나 저RS2군은 펙틴군과 유사하였다. 변 중 수분함량은 식이섬유 간에 유의적 차이가 없었으나 장 통과시간은 셀룰로오스군과 RS3 투여군이 펙틴군에 비해 유의적으로 단축되는 것으로 나타났다. 본 연구 결과는 변비 동물에서 저항전분의 투여는 식이효율과 체중 증가를 억제하는 작용이 있고, 저항전분 중 RS3는 셀룰로오스와 마찬가지로 변비 동물의 배변량을 증가시키고 장 통과시간을 단축시켜 배변 상태를 개선시킬 수 있는 가능성을 나타내었다.

The present study was conducted to evaluate the effects of resistant starches (RS2, RS3) on weight change and defecation states in rats with constipation induced by loperamide. Sixty male Sprague-Dawley rats were divided into the following six groups: normal control-5% cellulose (NC), constipated-5% cellulose (CC), constipated-5% pectin (CP), constipated-5% RS2 (CR2), constipated-8% RS2 (CR2-H) and constipated-5% RS3 (CR3). The animals were fed AIN76-based experimental diets for 5 weeks. Supplementation of RS2 and RS3 resulted in significantly lower feed efficiency ratios and body weight gain as compared to cellulose supplemented group. Large intestine length was significantly longer in the resistant starch and cellulose groups than in the pectin group. Relative fecal weight to feed intake was significantly higher in the RS3 resistant starch group than in the pectin group, and the appearance of feces was similar to that of the cellulose group. Supplementation of RS3 or cellulose significantly shortened gastrointestinal transit time in the constipated rats as compared to pectin. The results of the present study demonstrated that resistant starch supplementation, especially RS3, may help in depress body weight gain and alleviate constipation through an increase of fecal weight and shortening gastrointestinal transit time in constipated animals.
