Objectives: The purpose of this study was to investigate the effect of Phellinus linteus cheonghyeol plus (PLCP) on antioxidant and inhibition of inflammatory factor expression associated with dyslipidemia in HUVEC. Methods: The scavenging activity of DPPH and ABTS radical of PLCP was measured in HUVEC. The expression levels of NF-κB, p-IκBα, ERK, JNK, and p38 proteins were measured after treating with TNF-α in HUVEC. The expression levels of MCP-1, ICAM-1, and VCAM-1 mRNA and biomarkers were measured after treatment with TNF-α in HUVEC Results: 1. PLCP increases DPPH and ABTS radical scavenging activity in a concentration dependent manner. 2. PLCP significantly decreased the concentration of NF-κB, p-IκBα, ERK, JNK protein compared to the control at concentrations of 100 ㎍/㎖ or more, and significantly decreased concentration of p38 protein at all concentrations. 3. PLCP significantly decreased MCP-1 mRNA expression levels at 100㎍/㎖ or more compared to the control. ICAM-1 and VCAM-1 mRNA expression levels were significantly reduced at all concentrations compared to the control. MCP-1, ICAM-1 protein expression levels were significantly reduced compared to the control at concentrations of 100 ㎍/㎖ or more, and VCAM-1 protein expression levels were reduced at all concentrations. Conclusions: These results suggest that PLCP has an antioxidant effect, and it has been experimentally confirmed that it can prevent or inhibit inflammatory diseases caused by dyslipidemia due to its inhibitory effect on inflammation-related factors in HUVEC.

Background: The mushroom Phellinus linteus (PL) has been shown to have the anti-tumor and immunostimulatory effects. We hypothesized that the hot water extract of PL (WEPL) exerts its significant immunostimulatory effect by inducing production of the Th1-derived cytokine interferon-${\gamma}$ (IFN-${\gamma}$) by T lymphocytes. Methods: T lymphocytes were isolated from the mice fed with 200 mg/kg of WEPL once a day for 4 weeks, and then stimulated with the mitogen concanavaline A (Con A). IFN-${\gamma}$ gene and intracellular protein expressions were analyzed by RT-PCR and flow cytometry, respectively. The production of IFN-${\gamma}$ was measured by enzyme-linked immunosorbent assay. Results: WEPL significantly enhanced the transcription of IFN-${\gamma}$ mRNA. The effect of WEPL on IFN-${\gamma}$ expression was further supported by a concomitant increase in the number of cells with intracellular IFN-${\gamma}$ protein as well as the secretion of IFN-${\gamma}$. However, WEPL did not modulate either gene expression or protein secretion of interleukin-4, a Th2-associated cytokine, by Con A-stimulated T lymphocytes. Conclusion: Our results demonstrate that one of the potentially beneficial anti-tumor and immunostimulatory effects of WEPL may be mediated through the enhancement of IFN-${\gamma}$ secretion by T lymphocytes.

In this study, we investigated the quality characteristics and optimum conditions of porridge containing rice incubated with Phellinus linteus mycelium (PLMR). Composition measurements of PLMR were moisture 13.05%, ash 0.88%, carbohydrate 78.65%, crude protein 6.29%, and crude lipid 1.13%, also glutinous rice composition was moisture 13.99%, ash 0.32%, carbohydrate 77.18%, crude protein 7.85%, and crude lipid 0.66%. The water absorption rate of PLMR increased with increasing soaking time during 6 hours. However, the water absorption rate of glutinous rice increased until 30 minutes of soaking time. The pH of porridge was decreased as PLMR contents increased. The viscosity of porridge was increased as PLMR contents increased, and it was the lowest for the control at 914.77 cP. However, spreadability of porridge was decreased as PLMR contents increased. In terms of color, lightness was the highest for the 50% level, redness was the highest for the 75% level, and yellowness was the highest for the 25% level. In terms of textural characteristics, hardness and fracturability were increased as PLMR contents increased, whereas springiness, cohesiveness and resilience showed reverse results. In terms of consumer acceptance, flavor, appearance, viscosity, delicate taste, and overall acceptability were not significantly different between samples. Hot taste was decreased as PLMR contents increased, whereas grittiness showed reverse results. In conclusion, the results indicate that adding 25~50% PLMR to porridge is optimal for a recipe.

We investigated the effects of healthful decoction utilizing Phellinus linteus(HDPL) for suppression in the process of carbon tetrachloride (CCl₄4)-induced inflammation(50% CCl₄ : olive oil=1:1, 1 ㎖/KgㆍB.W.) of rat using biochemical, Western, histological and immunohistochemical analysis. Biochemical analysis of serum showed that the level of aspartate aminotransferase, alanine aminotransferase, lactate Dehydrogenase, alkaline phosphatase and triglyceride were significantly decreased by pretreatment of HDPL, but albumin and nitric oxide were increased. Immunoblot analysis of the liver showed that CCl₄-induced expression of interleukin-1β(IL-1β) and inducible nitric oxide synthase(iNOS) was inhibited by pretreatment of HDPL. More severe histopathological changes of the liver such as Kupffer cell reaction, inflammatory cell infiltration and focal necrosis were demonstrated in the rats challenged with CCl₄ compared with normal. Fewer scores of these changes were observed in the HDPL pretreated rats. Immunohistochemical analysis of the liver showed that while the expression of IL-1β, iNOS, tumor necrosis factor-α, COX(cyclooxygenase)-1 and COX-2 tended to increase, a decline of these immunoreaction of HDPL pre-treated groups were observed in the hepatocytes, especially in the focal necrotic sites. These results suggest that HDPL may act as a therapeutic agent for liver disease through a regulation of inflammation-related proteins.

This study was carried out to investigate the quality characteristics of breads with added Phellinus linteus grown in brown rice (BRPL). For color values, with increasing added BRPL powder, "lightness" decreased in the crumb while "redness" and "yellowness" increased ($^{***}$ p<0.001). The highest scores in volume and specific volume were observed in white pan bread with 5% BRPL powder added. When 10%, 15%, and 20% BRPL powder were substituted for equal amounts of strong flour, the volume and specific volume ratios of white pan bread decreased ($^{***}$ p<0.001). In texture measurements for white pan breads, hardness decreased slightly with the addition of 5% BRPL powder, but significantly ($^{***}$ p<0.001) increased with addition of 10%, 15%, and 20% BRPL powder. The addition of the BRPL powder significantly increased the springiness, gumminess, and brittleness of the white pan bread. The highest sensory scores for color, flavor, taste, and overall acceptance were obtained from white pan bread with 5% BRPL powder added ($^{***}$ p<0.001). By the results of these experiments, we can conclude that the hightest quality of bread with added BRPL powder has no more than 10% added BRPL powder content.

The immunomodulating activity of Kp, an antitumor protein-polysacchanide preparation from the shake-cultured mycelia of Phellinus linteus, was investigated in ICR mice subcutaneously implanted wit $1\times10^6$ cells of sarcoma 180. The mice were intraperitoneally administered with Kp at a does of 100 mg/kg once daily for five consecutive days starting from 24 hrs after the tumor implantation. Ten days after the last injection, the mice were immunized with $1\times10^7$ or $4\times10^8$ sheep red blood cells (SRBC) and five days later, the antibody-forming immune response were assessed by direct hemolytic plaque assay. To an immunization does of $1\times10^7$ SRBC, the Kp-treated mice elicied a successful humoral immune response despite the turmor-burden and produced $259\times10^3$ plaque-forming cells (PFC)/spleen, while the corresponding tumor-bearing control mice showed virtually no reponse $(2.0\times10^3$ PFC/spleen) (the stimulation index=129.5). However, to an immunization dose of $4\times10^8$ SRBC, both of the control mice and Kp-treated mice showed almost the same level of strong humoral immune response. From these data it is clear that Kp effectively restores the humoral immune response of the turmor-bearing ICR mice.

It was examined the effect of fermented rice wine using mycelium of Phellinus linteus (FWPL) on the gastric mucosa of rat. The gastric mucosal lesions were not seen macroscopically in normal, but ethanol-administrated rats produced congestion and edema with a few local lesions. The administration of FWPL showed a similar pattern as like normal except trace histopathological changes. The results of Western blot analyses showed that the higher expression of inducible nitric oxygenase (iNOS), cyclooxygenase (COX)-1, COX-2, tumor necrosis factor-$\alpha$ and c-fos, especially COX-2, in the ethanol-administrated rat compared with normal rat. But FWPL-administrated rat showed a trace increase of these expression compared to normal rat. About immunohistochemical observations, weaker iNOS reactions were detected in mucous cells of epithelim of ethanol administrated rat compared with normal and FWPL-administrated rat. These results suggested that FWPL-administrated rat showed a trace changes on the mucus barrier-related protein expression compared with ethanol-administrated rat and thus FWPL may be use to develop a functional alcoholic beverage.

It was examined that the effect of fermented traditional wine made by using mycelium of Phellinus linteus (TWPL) on the expression of inflammation-related proteins in rat liver. Levels of aspartate aminotransferase (AST) was significantly increased in the serum of ethanol-treated rats compared to normal. However, the level of AST showed no significant changes in the TWPL-treated rat compared normal. Slight histopathological changes of liver such as cloudy swelling, inflammatory cells infiltration, Kupffer cell reaction were demonstrated in the rats challenged with ethanol compared with normal. Fewer scores of these changes were observed in TWPL-treated rat with recovered glycogen in hepatocytes of whole hepatic lobule. The RT-PCR and Western analysis showed that the expression of inflammatory proteins such as cyclooxygenase-2, inducible nitric oxide synthase, tumor necrosis factor (TNF)-${\alpha}$ were decreased in the TWPL-treated rat compared with ethanol-treated ones. Immunohistochemical analysis showed that the expression of interleukin-lf and TNF-${\alpha}$ tended to decrease in TWPL-treated rat compared with ethanol-treated ones. These results suggest that TWPL may contains some protective agent for alcohol-induced liver injury through a regulating inflammation-related proteins.
