The physicochemical properties of carrot beverage fermented by Leuconstoc mesenteroides SM isolated from carrot juice were dependent upon the sucrose concentration and beet extract content. The addition of beet extract increased the consistency index and bioconversion of sucrose in the carrot juice fortified with Phellinus linteus extract, showing the highest consistency value at 2% beet extract. The polyphenol content and antioxidant effect of fermented carrot beverage were increased as the content of beet extract increased. Particularly, the consistency of fermented carrot beverage was greatly increased by the cold storage for 120 hr. After the cold storage for 2 weeks, fermented carrot beverage fortified beet extract showed the red-purple color with higher color value (a) and the viable cell counts of $10^9$ CFU/mL.

We have examined the effect of water extract of Phellinus linteus, a raw material of Korean traditional herbal medicine, on the induction of HL-60 cell differentiation. The proliferation of HL-60 cell was inhibited dose-dependently by treatment with various doses of P. linteus extract. It also caused a significant change in NBT reduction (7.5 times). The expression of CD11b and CD14 was increased in the cells treated with the extract, especially in those arrested at G0/G1 stage, which suggested that some components in P. Linteus extract induced HL-60 cell differentiation to granulocytic and monocyte lineages. Moreover, the expression levels of $p21^{WAF1/CIP}$ and $p27^{KIP}$ were up-regulated during HL-60 cell differentiation induced by P. Linteus extract. These results together suggest that P. Linteus extract contains potential HL-60 cell differentiation agents.

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.

In this study, the protective effect of rice with Phellinus linteus mycelium (PLMR) against hydrogen peroxide-induced oxidative stress was assessed in a mouse hippocampal neuronal HT22 cell line through (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) salt (MTS) assay and western blot. MTS assay using HT22 cells showed that PLMR extract did not affect viability at a concentration range from 1 mg/mL to 5 mg/mL. However, at concentrations over 10 mg/mL, PLMR extract resulted in increased cell death. Cell viability of HT22 was significantly reduced by $H_2O_2$ treatment, and reduction of cell viability was efficiently restored by treatment with PLMR extract in a dose-dependent manner from 0.1 to 1 mg/mL. Cells treated with $H_2O_2$ showed increased expression of Bax, a pro-apoptotic protein, which was down-regulated by treatment with PLMR extract. On the other hand, cells treated with $H_2O_2$ resulted in reduced expression of Bcl-2, an anti-apoptotic protein, which was restored by treatment with PLMR extract. In addition, treatment with PLMR extract reduced expression of cleaved caspase 3 and PARP, which were up-regulated by $H_2O_2$ treatment. The results may suggest that treatment with PLMR extract would suppress $H_2O_2$-induced apoptosis of HT22 cells.

In this study the ITS1, ITS2 and 5.8S ribosomal DNA sequences from 29 strains of the Genus Inonotus and its related genera were compared with 31 strains obtained from GenBank database. Using the neighbor-joining (NJ) method and most parsimonious analysis the phylogenetic tree was constructed. The hymenochaetales formed no monophyletic group and several non-hymenochaetales appeared as intermingled with the Hymenochaetales. Strains 6, 46, 49, 50, 53, 55 showed no certain affinities within the Hymenochaetales, whereas Inonotus sp. (51) was closely related to Phellinus baumii, and Inonotus sp. (52), and Inonotus glomeratus (10) was related to Phellinus linteus, and Fomes fomentarius (30) was related to Ganoderma lucidum. Inonotus sp. and Phellinus sp. formed no monophyletic groups and a subdivision in the following genera is accepted: Inonotus sp. Phellinus baumii, Phellinus linteus, Phellinus igniarius, Phellinus pini, Hericium erinaceum, Ganoderma lucidum and Sparassis sp. were confirmed and separated genera. The taxonomic status of Inonotus remained uncertain. Eight new combinations are proposed.

This study investigated the effects on the biological activities of germinated brown rice soaked in mycelial culture broth of Phellinus linteus. The level of free amino acid was higher in the GBRP extract than those of BR and GBR. The major free amino acids were alanine, valine, isoleucine and methionine in both extracts. The level of ${\gamma}$-aminobutyric acid (GABA) was also increased significantly in the GBR and GBRP. Antioxidant activities of methanol extract of BR, GBR and GBRP were measured by using DPPH radical scavenging and SOD-like activity. Antioxidant activities showed the highest level of 83% and 76% when 100 mg/ml GBR and GBRP, respectively. Stimulation of the macrophages RAW264.7 cells with lipopolysaccharide (LPS) resulted in increased production of nitric oxide (NO) in the medium. However, the methanol extract of GBR and GBRP showed marked inhibition of NO synthesis in a does-dependant manner. These results showed that GBR and GBRP were significant role for activation of immune system in the pathogenesis of inflammatory diseases.

To investigate the industrial availability of liquid fermentation (PL-ferment) by Phellinus linteus mycelium as a postbiotics for the inhibition of inflammation, PL-ferment was fractionated into culture supernatant (CS), hot-water extract (HW) from PL-ferment, EtOH-precipitate (CP) fractionated from HW, and the dialysate (DCP) of CP. Compared to the other fractions, DCP which is expected to contain exopolysaccharide (EPS) as the major component, significantly decreased the production of NO, IL-6, and MCP-1 in LPS-induced RAW 264.7 cells, and IL-6 and IL-8 in TNF-α and IFN-γ-induced HaCaT cells. The general component analysis results showed that no significant difference in components was observed between the fractions, whereas sugar composition analysis revealed that DCP had decreased glucose and increased mannose contents compared to the other fractions. This suggests that mannose played an important role in the anti-inflammatory activity of the active fraction, DCP. Molecular weight distribution analysis revealed that DCP was mainly composed of low-molecular-weight material-removed high-molecular-weight polysaccharides of 18-638 kDa, suggesting that EPS originated from P. linteus EPS. In conclusion, our results suggest that the DCP of P. linteus mycelium fermentation using the anti-inflammatory activity could be used industrially as postbiotic material.
