Abstract

This study was aimed at investigating whether dietary therapy using medicinal enzyme powder is effective in reducing constipation caused by loperamide in rats. Nine-week-old male Sprague Dawley were subdivided into 4 groups: normal diet group (C), loperamide treatment and normal diet (CL), medicinal enzyme powder diet (E), and loperamide treatment and medicinal enzyme powder diet (EL). Constipation was induced by subcutaneous injection of loperamide (1.5 mg/kg) 3 days prior to sacrifice. The treatment with loperamide led to an increase in weight gain, a decrease in the number and wet weight of fecal pellets, and a decrease in intestinal motility. The administration of the medicinal enzyme powder significantly reduced weight gain but increased intestinal mobility compared with the loperamide-treated group. The treatment with loperamide in the normal diet group reduced the activities of both suggesting that constipation may be involved in the low level of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT). Additionally, the loperamide treatment in the medicinal enzyme powder diet group increased the level of GOT, but reduced the level of GPT. Loperamide treatment also reduced cholesterol and increased the atherogenic index (AI) and cardiac risk factors (CRFs). Interestingly, the treatment with the medicinal enzyme powder effectively attenuated both the increase in AI and the reduction in high density lipopretein (HDL)-cholesterol, caused by the treatment with loperamide. Although there were no significant differences in the blood protein level, including hemoglobin and hematocrit, between the normal diet group and the loperamide-treated group, the administration of the medicinal enzyme powder to the loperamide-treated group effectively increased the levels of both hemoglobin and hematocrit. Collectively, the results demonstrate that the medicinal enzyme powder can help to combat the negative events caused by constipation.

변비는 일상생활에서 식욕저하와 복부 팽만을 일으키며 더 나아가서 피부 노화, 두통, 피부 질환, 그리고 대장암을 일으킨다고 알려져 있다. 본 연구는 정상식이에 비해 약선효소 분말식이가 loperamide로 유도된 변비 쥐의 장 운동과 간 기능, 지질상태, 그리고 혈액학적 성분에 개선에 대한 효능을 검증하고자 실시하였다. 3일 동안 loperamide 투여로 유발된 변비 쥐의 일일 체중증가와 사료효율은 높았으며, 이때 효소식이의 공급으로 일일 체중 증가량이 조절되었다. 또한 변비 쥐의 변 개수, 변 중량 및 수분함량, 그리고 장 운동은 정상 쥐에 비해서 감소하는 경향을 보였으며, 효소식이를 공급시켰을 때 장 운동이 증가되었다. 간 기능 지표인 GOT와 GPT 활성도는 정상식이 섭취군에서는 변비로 인하여 유의적으로 낮은 활성도를 보였다. 그러나 효소식이 섭취군에서는 변비유도로 GOT 활성도는 증가 된 반면에, GPT 활성도는 감소되었다. 변비 쥐의 혈액 내 중성지방, 총 콜레스테롤, LDL-콜레스테롤 농도는 효소식이에 의한 저하효과는 없었으나, HDL-콜레스테롤과 동맥경화 및 심혈관계 지수에 대해서는 효소식이가 보호효과를 보였다. 혈액학적 성분으로 단백질 농도는 변비와 식이에 의한 영향을 받지 않았으나, 변비로 인하여 저하된 헤모글로빈 농도와 헤마토크리트치는 효소식이 공급으로 증가시킬 수 있었다. 이상의 실험 결과에서는 loperamide로 유도한 변비 쥐에서 장 운동성 저하, 동맥경화와 심혈관계지수, 그리고 헤모글로빈농도와 헤마토크리트치 등에 대해서 약선효소 식이가 다소 효과를 보인 것으로 나타났다. 그러나 향후 만성적 변비에 대한 약선효소 식이효과에 대한 보다 심층적이 연구가 필요하며, 이러한 결과를 바탕으로 변비에 대한 약선효소 분말과 같은 천연물질의 기능성식품으로 연결된 산업화로 경제적 이익 창출과 변비의 예방으로 심혈관계 질환과 암의 발병률을 줄이고 변비 대한 식단개발을 위한 기초자료로 활용할 수 있을 것이라고 생각된다.
