Abstract

The water-soluble materials extracted from fruit bodies and mycelium of H. erinaceum were prepared. In-vitro anticancer activities on cancer cells and In-vivo proliferation effect on mouse peritoneal exudate cell and spleen cell of samples were investigated. Also, nitric oxide (NO) generation of peritoneal exudate cell, IL-2 production capacity of spleen cells and phagocytic activity of peritoneal macrophages were examined. The water extracts of H. erinaceum suppressed the proliferation of cancer cell (HeLa, Raw264.7, Jurkat, KATO3, EL4, LyD9) with concentration-dependent. The water extract from fruit body showed better suppression effect than that from mycelium in most of cancer cells used. The anticancer effect of water extract of fruits body in the range of 0.01 and 10 mg/ml for Raw 264.7 and EL4 cell lines were the same as the Taxol with one thousandth equivalent of fruit body concentration. Water extracts of fruit body and liquid-cultured products of H. erinaceum induced nitric oxide (NO) generation of peritoneal exudate cell and increased NO generation by stimulus of lipopolysaccharide. Water extracts alone did not induce the proliferation and IL-2 production capacity of spleen cells. However, spleen's proliferation and IL-2 production were induced significantly by the addition of lipopolysaccharide and Con A (concanavalin A) or Con A alone, and the effectiveness of mycelium extract with water were more active than those from fruit body.

H. erinaceum은 현재 산업적으로 매우 주목되고 있는 기능성 소재들 중의 하나이다. 본 연구에서는 식용은 물론 각종 약리효과를 나타내는 H. erinaceum의 기능성 식품의 제품화 연구 일환으로, 지금까지 체계적으로 연구된 바 없는 H. erinaceum의 액체배양을 시도하고, 생성된 균사체의 생리기능성의 변화를 자실체의 물 추출물과 비교, 조사함으로써 H. erinaceum 액체배양 생성물의 생리기능 효과를 평가, 규명하고자 하였다. H. erinaceum의 자실체 및 균사체 물 추출물은 HeLa (human cervix epitheloid carcinoma; 인간 자궁 상피암세포), Raw264.7 (mouse monocyte macrophage; 생쥐 단핵 대식세포), Jurkat (human acute T cell leukemia, 인간 급성 T 백혈병 세포), KATO3 (human gastric carcinoma 인간 위장 암세포), EL4 (mouse T lymphoma 생쥐 T 림프종 세포), LyD9 (mouse bone marrow plurypotent stem cell; 생쥐 공수유래 간세포) 등 각종 암세포주에 대해 농도 의존적으로 증식 억제 효과를 나타내었다. 자실체 추출물은 균사체 추출물보다 대부분의 암세포 증식의 억제 효과가 컸으며, 가장 높은 암세포 증식 억제효과를 보인 자실체 열수 추출물의 효과는 Raw 264.7 및 EL4 세포주를 사용한 Taxol와의 비교실험 결과, 자실체 농도 0.01$\sim$10 mg/ml에서 자실체 사용량의 1/1000에 상당하는 양의 Taxol 효과와 비슷하였다. 자실체 및 균사체 열수 추출물들은 1 mg/ml 농도에서 복강세포의 nitric oxide 생산 유도능을 나타내었으며, lipopolysaccharides 자극으로 더욱 증가하였다. 반면, 비장세포의 증식유도능 및 interleukin-2 유도능에서는 각 시료 단독으로는 증식 유도 및 interleukin-2 유도능을 나타내지 않았으나 각각 lipopolysaccharide와 concanavalin A의 첨가 및 concanavalin A 자극으로 강한 증식유도능 및 interleukin-2 생산능을 나타내었고, 그 효과는 균사체 추출물에서 자실체 보다 더욱 높았다. 또 각 시료는 골수세포에 대해서도 약간의 증식효과를 보였으며, 복강세포의 탐식능을 나타내었다.
