In this study, the protein content and functional changes in soybeans cultured with Phellinus linteus HN00K9 were analyzed. P. linteus HN00K9 was cultured on soybeans. The crude protein content in soybeans cultured with HN00K9 (PMS) was 41.99%, which was higher than that in soybeans not cultured with the mushroom (UCS). The total free amino acid content in PMS increased to 39,963 mg/100 g, which was higher than that in UCS (36,817 mg/100 g). In particular, in PMS, glutamic acid accounted for 18.5% of the total amino acids at 7,413 mg/100 g. The total polyphenol content in PMS was 2.66 mg GAE/g, which was more than 45% higher than the amount in UCS (1.45 mg GAE/g). Additionally, PMS showed a DPPH radical scavenging activity of 33.3%, which was 3 times higher than that exhibited by UCS (11.5%), reflecting its high antioxidant content. Therefore, the PMS in this study has potential for use as a functional food material.

The effects of mycelium cultural extract supplemented diet, hematology and disease resistance against Vibrio anguillarum in juvenile flounder, Paralichthys olivaceus were evaluated. Fish were fed the Phellinus linteus with Coriolus militaris versicolor mixed mycelium cultural extract supplemented diet, Phellinus linteus mycelium cultural extract supplemented diet and Coriolus militaris tmycelium cultural extract supplemented diet a commercial diet for 12 week. The body weight and length gain from the fish fed on daily the phellinus with coriolus versicolor mixed mycelium cultural extract supplemented diet, phellinus linteus mycelium cultural extract supplemented diet and Coriolus versicolor mycelium cultural extract supplemented diet of each mycelium cultural extract were higher than the control and the Glutamic oxalacetic transaminase (GPT) were of lower than the control. The relative precent survival rate (RPS) after an artificial challenge with $7{\times}10^5\;CFU$ of Vibrio anguillarum per fish was higher than the control.

$\beta$-Glucans, which were isolated from sangwhang (Phellinus linteus), were subjected to reductive amination and the biological properties of the derivative were investigated. The degree of substitution of the aminated sangwhang $\beta$-glucan was calculated by elemental analysis to be 1.13. Bronchoalveolar lavage (BAL) experiments showed that the aminated derivative increased nitric oxide production. In addition, the amination enhanced in vitro cytotoxic activities against HT1080 and SNU-C2A cell lines. Thus, the aminated derivative is shown to enhance immune systems by the incorporation of amino groups into the polymer structure.

The current study was performed to determine the acute oral toxicity of a crude extract of sanghwang mushroom (Phellinus linteus), in SD rats. 5 rats of each sex were orally treated with a single dose of extract of sanghwang mushroom at doses of 0, 500, 1,000, 2,000 mg/kg, respectively. After the treatment, clinical signs and body weight change, the food and water consumption were observed for 14 days. All animals survived during the study and did not show any clinical signs. Body weight gain showed no significant difference between the control and treated rats. However, body weight gain delayed in high dose group (2,000 mg/kg) on day 1~3 after administration. Another 5 rats of each sex were orally treated with a single dose of extract of sanghwang mushroom at dosages 4,000, 5,000 mg/kg respectively, but all animals survived during the study and did not show any clinical signs. It is suggested that LD$_{50}$ of extract of sanghwang mushroom by oral administration was estimated to be over 5,000 mg/kg in both sexes of rats.s.

The hypolipidemic effects of soybeam paste containing mycelia of Phellinus linteus, Cordyceps militaris, Ganoderma lucidum were evaluated in hyperlipidemic rats. Body weight of the rats fed with soybean paste containing mycelia of Ganoderma lucidum (ESG) were significantly lower than control group whereas, there was no significant difference in body weight in order diet groups. Food intake, food efficiency ratio, and liver and kidney weights were not significantly different among the diet groups examined. However, the spleen weight of ESG group was markedly lower than other groups. Significant decreases in serum total cholesterol, LDL-cholesterol and liver total cholesterol were also observed in all diet groups tested. All groups fed with soybean paste containing mycelia of mushroom were also observed in all diet groups tested. All groups fed with soybean paste containing mycelia of mushroom were almost equally effective in increasing plasma HDL level and decreasing the atherogenic index, whereas the ratio of HDL to total cholesterol was significantly increased in all experimental diet groups.

This study was carried out to observe the antioxidative activity, fibrinolytic activity, nitrite savenging ability and adenosine content of three medicinal mushrooms. Among water and ethanol extract of each mushroom, water extract of Inonotus obliquus (Czech) showed the highest antioxidative activity $(57.1{\mu}g/ml)$, nitrite scavenging ability (52.04%), fibrinolytic activity (86.8%) and adenosin content $(94.3{\mu}g/g)$, whereas nitrite scavenging ability of ethanol extract of Phellinus linteus showed higher than that of water extract. Apart from the above statements, water was effective than ethanol as extracting solvent in general. These results suggest that Inonotus obliquus (Czech) showed higher activities such as antioxidative activity, nitrite scavenging ability, fibrinolytic activity and adenosin content and water was effective as solvent except for nitrite scavenging ability.

In order to investigate whether or not CCD-980sk cell line can be affected by Korean Citrus junos and medicinal herbs, we examined the MTT assay when we treated Korean Citrus junos and medicinal herbs in CCD-986sk human fibroblast cell line. The samples that added complex of grinded extracts of Korean Citrus junos and boiling-water extracts from Korean medicinal herbs were tested toy cell proliferation activity by means of a modification of the MTT assay. Among mixture of Citron 3 (Citron 3, less mellowed citron which was ripened for three months) and boiling-water extracts, the group Citron 3+Phellinus linteus showed significantly strong cell proliferation activity. And among mixture of Citron 4 (Citron 4, completely mellowed citron which was ripened for four months) and boiling-water extracts, the group Citron 4＋Cordyceps militaris and Citron 4+Phellinus linteus showed significantly strong cell proliferation activity, respectively. These results suggest that complex of Korean Citrus junos and medicinal herbs could be an excellent candidate toy protection of human skin aging.

The ${\gamma}$- and ${\beta}$-secretase are one of the most important proteases, which cleave amyloid precursor protein (APP) into neurotoxic A${\beta}$ peptide in Azheimer's type dementia. In the course of screening for anti-dementia agents from natural products, the mycelial culture of mushroom Phellinus linteus showed potent inhibition againt ${\beta}$-secretase (BACE1). (omitted)

In anti-cancer therapies, radiotherapy and chemotherapy show a superior inhibition effect on cancer cell growth, but those are very toxic to normal tissues and organs. Particularly, drugs for neutropenia, one of chemotherapy agents, which suppress the function of bone marrow, are needed to be controlled in terms of their dosage and therapy period because of their side effect. Phellinus linteus polysaccharide (PL) has been reported to increase the number of splenocytes and bone marrow cells. PL has been shown to decrease the side effects of cyclophosphamide (CYC) treatment to the cancer patients. PL showed no effects in semisolid clonogenic assay, suggesting that PL doesn't contain substantial compounds to substitute for colony stimulating factors (CSFs). On the other hand, PL increased the expression of SCF, IL-3, GM-CSF, TPO genes. These results indicate that PL may promote the growth and proliferation of splenocytes and bone marrow cells through indirect or CSFs-dependent pathway, which may lead to a hematopoiesis.
