Abstract

The preventive effect of Lentinus edodes extract (LE) against constipation was studied in rats. Rats were pretreated with LE contained in drinking water at the concentration of 10%, 20% and 40% over 30 days. Constipation was induced by subcutaneous injection of loperamide (4 mg/kg/day) 3 days prior to sacrifice. Treatment of loperamide resulted in decreases in the number and wet weight of fecal pellets, and increase in the number of fecal pellet in the distal colon and cecocolon weight. In contrast, the number and wet weight of fecal pellets were increased, and the number of fecal pellet in the distal colon and the cecocolon weight were decreased in LE-pretreated groups compared to the loperamide-treated group. Blood parameters such as white blood cell, red blood cell, hemoglobin, hematocrit, platelet, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration, and serum alanine transaminase, aspartate aminotransferase and alkaline phosphatase activities, and blood urea nitrogen and creatinine values were not significantly different between the groups. In addition, LE (0.5 mg/mL) increased spontaneous contractile activity, which was reduced by atropine or loperamide in isolated rat ileum. Theses results suggest that the improvement of constipation symptoms in LE-pretreated rats resulted from a stimulatory effect of LE on intestine contractile activity.

표고버섯 추출액을 10, 20 및 40%로 30일간 음용수에 섞어 실험동물에 투여하고 실험 28-30일에 loperamide(4 mg/kg/day, s.c.)로 변비를 유도한 뒤 표고버섯 추출액의 변비 예방효과를 측정하였다. Loperamide를 단독 투여한 군은 정상 대조군과 비교하여 변의 개수 및 중량이 유의적으로 감소하였으며 원위 결장 내 변잔류의 증가 및 cecocolonic segment의 무게가 증가하였다. 표고버섯 추출액 및 loperamide를 투여한 군은 loperamide를 단독 투여한 군과 비교하여 변의 개수 및 중량이 유의적으로 증가하였으며 원위 결장 내 잔류 변 및 cecocolonic segment의 무게도 감소하였다. 이러한 결과는 표고버섯 추출액이 in vivo에서 변비 개선효과가 있음을 보여준다. 변의 수분함량은 실험군 간의 유의한 차이가 없었지만 loperamide에 의한 변비 유발 시 감소하는 경향이 있었으며, 표고버섯 추출액 투여군에서는 변의 수분함량 감소가 다소 완화되었다. 한편, 혈 중 WBC, RBC, HGB, HCT, PLT, MCV, MCH, MCHC치 및 혈청 ALT, AST, ALP, BUN 및 creatinine 수치는 정상 대조군, loperamide 처리군 및 표고버섯 추출액 처리군 사이에서 차이가 없었다. In vitro 실험결과, 회장 적출 절편에 표고버섯 추출액 동결건조물(0.5 mg/mL)을 전 처리 시 loperamide에 의한 장력과 진폭 억제가 부분적으로 차단되었으며, atropine에 의해 유도된 진폭의 억제도 효과적으로 차단되었다. 이러한 결과는 표고버섯 추출물의 변비 개선효과가 장의 운동성 촉진과 관련이 있음을 시사한다.
