Ganoderma lucidum has been traditionally used as a medicine for treatment of bronchitis, arthritis, and high blood pressure, and it has been reported to display many biological activities including anticancer and immune activities. Since mushroom mycelium is known to have excellent biological activities together with mushroom fruiting body, studies on biological activities of mushroom mycelium have been actively conducted. Thus, the present study compared the biological activities before and after the cultivation of Ganoderma lucidum mycelium on Atractylodes rhizoma. When the radical scavenging activity was assessed by the DPPH assay, ARGL (ethanol extract of Atractylodes rhizoma mycelium fermented with Ganoderma lucidum) showed radical scavenging activity of 5.58~82.56% at concentrations of $10{\sim}500{\mu}g/assay$, while AR (ethanol extract of Atractylodes rhizoma) showed radical scavenging activity of 5.27~72.08% at the same concentrations. When measured by using the ABTS assay, ARGL showed higher radical scavenging activity than AR, which was consistent with the result obtained by the DPPH assay. In the MTT assay, the cytotoxicity of ARGL against all cell lines was higher than that of AR. In particular, the cytotoxicities of AR and ARGL against Hep3B at a concentration of $400{\mu}g/assay$ were 71.81% and 86.40%, respectively. In addition, the result obtained by the SRB assay was consistent with the result obtained by the MTT assay. According to the results mentioned above, there is a high probability that medicinal herb cultures using mycelium can be used as sources of functional foods since the cytotoxicities against cancer cells and antioxidant activities increased when the mycelium was fermented with Atractylodes rhizoma.

본 논문에서는 꽃송이버섯을 4종의 유산균(Lactobacillus plantarum subsp. plantarum, L. acidophilus, L. helveticus, L. delbrueckii subsp. bulgaricus)을 사용해 발효를 하였다. 발효된 꽃송이버섯 발효물을 항산화 활성(DPPH free radical scavenging activity, ABTS radical scavenging activity, Hydroxy radical scavenging activity), SOD activity, 총 폴리페놀 함량(TPC), HPLC 분석, protease 활성을 동해 발효 전 후 생리활성 변화를 확인하였다. 꽃송이버섯 발효물의 항산화 활성은 IC50 28.09-64.46 ㎍/mL, SOD 활성은 IC50 15.75-39.42 ㎍/mL, TPC는 57.66-100.43 GAE ㎍/mL 와 85.25-110.68 ㎍/mL 로 확인되었다. 꽃송이버섯 추출물의 항산화 활성보다 약 8배 이상 증가된 결과로 확인되었다. 또한 꽃송이버섯 발효물의 HPLC 분석 결과는 ascorbic acid, gallic acid, chlorogenic acid의 함량이 높게 확인되었으며, protease 활성 또한 발효물의 활성이 높은 것으로 확인되었다. Lactobacillus 균주들의 작용에 의하여 꽃송이버섯이 발효되면서 폴리페놀류가 증가하여 생리활성이 꽃송이버섯 추출물에 비해 증가한 것으로 추측된다. Lactobacillus 균중에서 L. helveticus 균주로 발효된 꽃송이버섯 발효물은 가장 높은 활성을 나타냈으며, 꽃송이버섯을 발효하는데 있어 L. helveticus 균주가 가장 적합한 균주로 확인되었다.

The present study was conducted to investigate the translocation of polyphenols, especially catechin derivatives, from mushroom medium mixed with green tea residues into fruiting body of Pleurotus eryngii. Pleurotus eryngii was grown on the media incorporated by mixing or surface-treated with dry materials including leaf petioles and young stems or leaves of green tea. The dry materials treated in medium did not affect plant height and fresh weight of Pleurotus eryngii body. From the samples of Pleurotus eryngii, the eight main catechin derivatives (-)-gallocatechin(GC), (+)-catechin (C), (-)-epicatechin (EC), (-)-epigallocatechin (EGC), (-)-epigallocatechin gallate (EGCG), (-)-gallocatechin gallate (GCG), (-)-epicatechin gallate (ECG), and (-)-catechin gallate (EGCG), and caffeine were analyzed quantitatively by HPLC. The results showed that EGC in Pleurotus eryngii was 45% more detected, when incorporated with the dry materials, than untreated control. Especially, content of EGCG was increased in surface-treated Pleurotus eryngii up to 3.2 ppm, while it was not detected or reduced in control and other treatments. Caffeine content was greatly increased regardless of treatment method, compared with control (0.1ppm), showing 44 fold-amount in Pleurotus eryngii at early growth stage when incorporated with the dry materials into medium. The results indicates that functional catechin derivatives of green tea would be partly translocated into Pleurotus eryngii throught incorporation and surface treatment with residues of green tea plants.

Lentinus squarrosulus (Mont.) is an edible wild mushroom with tough fruiting body that belongs to the family Polyporaceae. It is used in ethnomedicine for the treatment of ulcer, anaemia, cough and fever. Recent studies have demonstrated its anticancer, anti-diabetic and antioxidant properties. However, little or no information is available regarding the bioactive components and toxicological study of wild dried L. squarrosulus. Therefore, this study investigated the bioactive components of aqueous extract of boiled wild dried L. squarrosulus and its toxicological effects in rats. The extract of L. squarrosulus was subjected to GC-MS analysis. The acute toxicity test was performed by oral administration of a single dose of up to 5,000 mg/kg extract of L. squarrosulus. In subacute study, the rats were orally administered extract of L. squarrosulus at the doses of 500, 1,000 and 1,500 mg/kg body weight daily for 14 days. The haematological, lipid profile, liver and kidney function parameters were determined and the histopathology of the liver and kidney were examined. The GC-MS analysis revealed the presence of bioactive compounds; 1-tetradecene, fumaric acid, monochloride, 6-ethyloct-3-yl ester, 9-eicosene, phytol, octahydropyrrolo[1,2-a]pyrazine and 3-trifluoroacetoxypentadecane. In acute toxicity study, neither death nor toxicity sign was recorded. In the sub-acute toxicity study, significant differences (p < 0.05) were observed on creatinine, aspartate aminotransferase, alanine aminotransferase, total cholesterol, triglycerides and high-density lipoprotein cholesterol. Whilst no significant differences (p > 0.05) were observed on packed cell volume, heamoglobin, red blood cell, white blood cell and alkaline phosphatase, in all the tested doses. No histopathological alterations were recorded. Our findings revealed that aqueous extract of L. squarrosulus may have antimicrobial, antinocieptive and antioxidant properties based on the result of GC-MS analysis. Results of the toxicity test showed no deleterious effect at the tested doses, suggesting that L. squarrosulus is safe for consumption at the tested doses.

This study was initiated in order to investigate the anticancer and immunomodulating activities of crude polysaccharides extracted in methanol, neutral saline, and hot water (hereinafter referred to as Fr. MeOH, Fr. NaCl, and Fr. HW, respectively) from the fruiting bodies of Panellus serotinus. Content of ${\beta}$-glucan and protein in Fr. MeOH, Fr. NaCl, and Fr. HW extracts of P. serotinus ranged from 22.92~28.52 g/100 g and 3.24~3.68 g/100 g, respectively. In vitro cytotoxicity tests, none of the various fractions of crude polysaccharides were cytotoxic against sarcoma 180, HT-29, NIH3T3, and RAW 264.7 cell lines at the tested concentration. Intraperitoneal injection with crude polysaccharides resulted in a life prolongation effect of 23.53~44.71% in mice previously inoculated with sarcoma 180. Treatment with Fr. HW resulted in an increase in the numbers of spleen cells by 1.3 fold at the concentration of $50{\mu}g/mL$ compared with control. Treatment with Fr. NaCl resulted in improvement of the immuno-potentiating activity of B lymphocytes by increasing the alkaline phosphatase activity by 1.4 fold, compared with control, at the concentration of $200{\mu}g/mL$. Among the three fractions, maximum nitric oxide ($13.48{\mu}M$) was recorded at $500{\mu}g/mL$ in Fr. HW. Production of tumor necrosis factor alpha, interleukin-$1{\beta}$, and interleukin-6 was significantly higher, compared to the positive control, concanavalin A, at the tested concentration. Therefore, treatment with crude polysaccharides extracted from the fruiting body of P. serotinus could result in improvement of antitumor activity.

Cordyceps militaris (CM) occurring from a fruiting body by a host insect is a kind of mushroom, which is composed of animal host and plant fruit body. CM contains large amounts of useful ingredients including polysaccharides, vitamins, amino acids, minerals, etc. The essential amino acids from CM including cystine, lysine, and methionine can be expected to improve damaged hair treatment as effective ingredients. In this study, the improvement effect of the CM extracts on chemical and physical properties for damaged-hair treatment was investigated. The cysteic acid and cystine monooxide produced by oxidation of cystine were analyzed their chemical structure by FT-IR spectroscopy. It was confirmed that the vibration absorption peak ($1,041cm^{-1}$) of cysteic acid was reduced and increased sulfur content considerably which means meaningful improvement effect on damaged-hair treatment. Apparently, the cuticle morphology of the damaged-hair was improved significantly by treatment with CM extracts. Especially, confocal laser scanning microscope images of the damaged-hair treated with the extract showed highly increased fluorescence intensity which means promising effect in hair treatment. The tensile strength of the damaged hair treated also increased by 168% compared with the damaged hair.
