Abstract

This study was performed to investigate the inhibitory effect of the water-extract from fermented compositions containing Inonotus obliquus with added Houttuynia cordata on the growth of either human AGS gastric and HCT-15 colon cancer cells or NIH3T3 normal mouse fibroblast cells. Cytotoxic activity on cancer cells was investigated by viable cell count, MTT assay and morphological observation. Mixtures of Inonotus obliquus with added Houttuynia cordata were fermented at $30{\sim}37^{\circ}C$, $50{\sim}60%$ humidity for 30 days, extracted with water, freeze dried, powered, and then dissolved in water for the experiment. In MTT assay, the fermented compositions exhibited inhibitory effects of 13, 25, 40, 67 and 78% for AGS and 22, 40, 50, 69 and 76% for HCT-15 at 0.16, 0.4, 0.8, 1.6 and 4.0 mg/ml, respectively. However, normal NIH3T3 cells were exhibited 86% survival under the same experimental condition. Fermented compositions showed highly inhibitory effect against human cancer cell line HCT-15 and AGS, but not on normal cell line NIH3T3.

어성초 분말을 포함하는 차가버섯 발효 조성물의 물 추출물이 인체 위암 세포 AGS 및 대장암 세포 HCT-15, 그리고 정상세포 NIH3T3 fibroblast의 세포 생육에 미치는 영향을 검토하였다. 세포독성 실험은 세포수 count와 MTT 방법으로 측정하였다. 어성초 분말을 포함하는 차가버섯 발효 조성물의 제조는 차가버섯과 어성초 분말을 혼합하고, 여기에 대두 발효 미생물원을 다시 혼합시켜 습도 $50{\sim}60%$,온도 $30{\sim}37^{\circ}C$에서 30일 정도 발효시킨 후 건조 시킨 분말에서 5% 물 추출물을 얻어 동결건조 시켜 실험에 제공하였다. MTT assay 방법에서 차가버섯 발효 조성물의 수용성 추출물 0.16, 0.4, 0.8, 1.6 및 4.0 mg/ml 첨가 농도에서 AGS 세포 생육은 13, 25, 40, 67 및78% 억제 되었으며, HCT-15세포 생육은 22, 40, 50, 69및 76%씩 각각 억제되었다. 그러나 동일한 실험조건에서 정상 세포수 NIH3T3은 86% 이상의 생존율을 나타내었다. 차가버섯 발효 조성물의 수용성 추출물은 인체 대장암 세포주 HCT-15와 위암 세포수 AGS에 대해 생육억제 작용이 강한 반면, 정상세포 NIH3T3에 대해서는 세포 독성을 거의 나타내지 않아 가장 바람직한 암예방 또는 항암식품 개발가능성을 제시하였다.
