  • Lentinus edodes (LE) is the first medicinal macrofungus to enter the realm of modern biotechnology. Lentinus edodes is well-known to have anti-tumor, anti-inflammatory, and immunomodulatory effects. In this study, osteoporosis was induced by ovariectomy in female rats, and the prevention and treatment efficacy of the climacteric disease the postmenopausal type I pattern was examined using the experimental substance. Female rats were either sham-operated (sham; n = 5) or surgically ovariectomized (OVX; five animals per group) and then administered to OVX control, raloxifene hydrochloride 1 mg/kg/day, or LE (20 and 200 mg/kg/day) for 12 weeks. LE treatment suppressed the ovariectomy-induced reduction of bone mineral density in the entire tibia as well as its metaphysis with a decrease of serum osteocalcin and interleukin-6 levels. In addition, LE is suggested to elevate the serum levels of progesterone hormones and prevent bone loss in ovariectomized rats. In conclusion, LE 200 mg/kg/day may have inhibitory effects on osteoporosis in OVX rats.

  • The effect of drying temperature (30, 40, 50, 60$^{\circ}C$) on chemical components of Shiitake mushroom(Lentinus edodss) was investigate. When compared proximate composition on pileus and stipe of raw and dried materials, all of them were found to be higher in the stipe part than in the pileus part. The major components of organic acid were oxalic, citric, malic, malonic and pyroglutaric acid. The contents of free and total amino acids in pileus and stipe were 3458.4, 7640.2mg% for pilueus; 2298.0, 6171.5mg% for stipe on dry basis, respectively. On the other hand, there was no significant difference in the changes of crude ash and organic acids content of Shiitake mushroom among drying temperatures. But the amount of crude fats was increased and that of reducing sugars was decreased with increase of drying temperature. The contents of crude proteins of pileus part of dried materials were increased with increased drying temperature, but those of stile part were gradually decreased. The contents of free amino acids decreased with increase in drying temperature, but those of total amino acids were gradually increased.

  • 표고버섯(Lentinus edodes) 균에 의한 졸참나무(Quercus serrata)골목의 미시형태적 변화를 주사형전자현미경 (SEM)을 통해 관찰하였다. 표고 재배 5년후 골목의 중량 감소율은 50%에 달했다. 구성세포중 목섬유는 표고균사에 의해 쉽게 분해되었으나 도관과 유세포는 저항성을 나타냈다. SEM 관찰 결과 표고균사는 세포내강(內腔)에서부터 세포벽을 서서히 분해 박벽화(薄壁化)시켰으며, 또한 Cell corner가 중간층보다 먼저 공격을 받아 분해 되었으나 중간층은 쉽게 분해되지 않았다. 흥미롭게도 연부후(軟腐朽)의 전형적 형태인 2차막에서의 공동(空洞)역시 백색부후균인 표고균사에 의해 형성 되었다. 이상의 관찰결과 표고균은 백색부후와 연부후균이 갖는 미시형태적 특징을 동시에 보여 주었다. 아울러 중간층 보다 Cell corner가 먼저 선택적으로 분해되며, 도관세포벽의 분해저항성을 세포벽 구성 리그닌의 화학적 특성과 연관시켜 논의했다.

  • To increase the production of mushrooms and the economic efficiency of mushroom cultivation, the pinchips(PC) and sawdusts(SD) of three Korean oak species were tested as cultivating media for Lentinus edodes with varing the composition of the media. The results are as follows. 1. Organic acids(tannic acid and citric acid), which were added in the PC medium to enrich the quality of mushrooms, did not increase the growths of the mycelia and the quality. 2. The mushrooms were able to be harvrested from six months after beginning the cultivation. No significant differences were found among the qualities of the mushrooms produced by various treatments. 3. The production rate of mushroom was relatively high with, 28.4~29.3% (700~730gr./2,500gr pack). The net profit estimated was about 1,450 won per pack.

  • Methanol and water crude extracts, crude polysaccharides and crude polysaccharides-free of water crude extracts from Shiitake mush-room (Lentinus edodes) were investigated for their antioxidant capacity in total polyphenolics and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Total polyphenolics in the crude polysaccharides-free of water crude extracts were higher than that of the other ones. And crude polysaccharides-free of water crude extracts and water crude extracts show high on DPPH free radical scavenging activity. Positive correlations were found between total polyphenolics and their antioxidant activity.

  • The carpophores of three Korean mushrooms, Coriolus versicolor, Pleurotus ostreatus, and Lentinus edodes were respectively extracted with hot water and the extract were dialyzed through Visking tube. They were found to contain an antinumor activity against sarcoma 180 implanted in mice. The components of these aqueous extracts were found to be polysaccharide and protein by color reactions including anthrone and Lowry-Folin tests. The hydrolysis of the polysaccharide with 3% HCI-MeOH and trimethylsilylation yielded four monosaccharides : glucose, mannose, galactose and xylose which were identified by G. L. C. After hydrolysis of protein with 6N HCL, fourteen to seventeen amino acids including aspartic and glutamic acids were detected by an amino acid analyzer.

  • The carpophores of three Korean mushrooms, Coriolus versicolor, Pleurotus ostreatus and Lentinus edodes were respectively extracted with hot water and the extracts were dialyzed through Visking tube. They were found to exert an antitumor activity against sarcoma-180 implanted in mice. Especially, the inhibition ratio of the extract of Coriolus versicolor (100 mg/ Kg.i.p) was almost 100% . But all the extracts did not affect the growth of leukemia L517Y cells in vitro. Therefore these facts indicate that the extracts appear to stimulate cell-mediated immunity.

  • To investigate constituents of Lentinus edodes grown on various, quantitative analyses of ash, crude protein, crude fiber, crude fat, water, nonsoluble nitrogen of the mushrooms were carried out by ordinary methods. The crude fat of the mushroom grown on chestnut tree(1.82%) was greater than that grown on oak (0.76%) or alder (1.17%) tree. The crude fiber of the mushroom grown on oak tree (12.50%) was greater than those grown on alder and chestnut trees, 9.85% and 8.52%, respectively. The crude protein, ash, nonsoluble nitrogen and water contents of the mushrooms grown on the three different trees were similar.
