Abstract

This study was conducted to investigate the effect of extract of Fomes fomentarius (FF) on blood glucose, lipid profile, antioxidant enzymes and immune cells in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into control, STZ-induced diabetic group (DM), STZ plus FF water extract treated group (DM-FW 200) and STZ plus FF methanol extract treated group (DM-FM 200). FW (200 mg/kg BW) and FM (200 mg/kg BW) were orally administered once a day for 14 days. Admdinistering FW and FM to STZ-induced diabetic rats lowered the blood glucose level. The supplementation of FW and FM suppressed the increase in the total cholesterol and triglyceride levels in the serum and liver of the diabetic rats. The high density lipoprotein-cholesterol level and glutathione peroxidase activity were higher in the FF-sup-plemented group compared to the diabetic group. Administering FW and FM increased the suppress in the serum complement component C3, whole blood B-cell, T-cell, helper T cell and suppressor T cell of the diabetic rats. Therefore, it could be suggested that FW and FM are alleviated the diabetic complication through enhancing the hyperglycemia and preventing diabetic complications.

말굽버섯(Fomes fomentarius)이 당뇨에 미치는 영향을 연구할 목적으로 실험동물에 STZ를 투여하여 당뇨를 유발시킨 후 말굽버섯 물추출물과 메탄을 추출물을 2주간 투여하여 혈당,지질함량 및 면역에 미치는 영향을 검토한 결과는 다음과 같다. 혈당은 당뇨로 인해 증가하였으나 말굽버섯 추출물 투여군에서 유의적으로 감소를 보였다. 혈청과 간의 총콜레스테롤과 중성지방 함량은 말굽버섯 추출물 급여로 DM군에 비하여 현저한 감소를 나타내었다. HDL-콜레스테롤 함량과 GSH-Px의 활성은 말굽버섯 추출물 급여 시 에는 DM군과 비교하여 유의한 증가가 나타났다. 혈청 보체 C3의 함량은 대조군에 비하여 DM군에서 유의한 감소를 보였고, DM-FM 200군에서 대조군 수준으로 회복이 관찰되었다. B cell과 T cell은 DM군에서 유의한 감소를 보였고, 말굽버섯 추출물 투여로 유의적으로 증가되었다. Helper T cell과 suppressor T cell의 분포는 DM군에서 유의하게 감소되었으나, 말굽버섯 추출물 투여로 유의한 증가를 나타내었다. 이상의 결과를 종합하여 볼 때 말굽버섯의 물 추출물과 메탄올 추출물은 혈당조절 기능, 지질대사 개선 및 면역작용을 활성화시킴으로서 STZ의 투여로 인한 당뇨의 증상을 완화시키는 것으로 사료된다.
