Objective : The purpose of this clinical research was to investigate the effects of herbal cosmetics containing Phellinus linteus extracts on patients with atopic dermatitis. Methods : A total of 35 patients who visited Daegu Hanny Oriental Medical Center from November 4th, 2008 to December 28th, 2008 were included in this study. In this study, we observed transepidermal water loss, skin moisture content, modified scorad index of atopic dermatitis and pruritic degree. Statistical analysis was performed by using paired t-test and wilcoxon signed ranks test. Statistical significance was achieved if the probability was less than 5%(p<0.05). Results : Statistically, herbal cosmetics containing Phellinus linteus extracts showed siginificant effect on transepidermal water loss, skin moisture content, modified scorad index of atopic dermatitis and pruritic degree(p<0.05). And satisfaction after using herbal cosmetics was near good. Conclusions : Considering the above results, we have concluded that herbal cosmetics containing Phellinus linteus extracts have the remarkable effects on atopic dermatitis.

The fruiting bodies of Sanghwang mushrooms, Phellinus linteus HN1009K (PLH) and Phellinus linteus (Korea Sanghwang, PLK), and Phellinus baumii (Jangsu Sangwhang, PB), were extracted with 70% methanol. The methanolic extracts of different concentrations ($5-200{\mu}g/ml$) showed inhibitory effects of 20-95% on plated aggregation induced by collagen (2.5 ug/ml), ADP (10 uM), and thrombin (0.1 U/ml). The PLH, PLK, and PB extracts (200 ug/ml) reduced ATP release from ADP-activated platelets by 50-60%. These results suggest that the methanolic extracts from Sanghwang mushrooms inhibit platelet aggregation.

This study was undertaken to investigate comparative anti-tumor activity of water extracts of Phellinus gilvus (PGE), Phellinus linteus (PLE), and Phellinus baumii (PBE) in vitro. The anti-tumor activity in the present study was evaluated by sulforhodamine B (SRB) and microtetrazolium (MTT) assay in terms of cell survival level. The tumor cells (sarcoma 180 and P388) were treated with PGE, PLE, and PBE (7.5, 15, and 30 $\mu\textrm{g}$/ml) and Doxorubicin (DOX) (0.001~10 $\mu\textrm{M}$). The results showed that DOX, PGE, and PLE inhibited proliferation showing a dose-dependent manner against both tumor cells. However, PBE was inhibited by the only 30 $\mu\textrm{g}$/ml in both cells proliferation. In conclusion, all of PGE, PLE, and PBE used in this study have shown anti-tumor activity against both sarcoma 180 and P388. Among them, PLE was the most effective in anti-tumor activity against sarcoma 180 (p<0.05) and PGE was against P388 in SRB assay. PLE, however, was against P388 (p<0.05) in MTT assay.

Anti-oxidative effect of Phellinus linteus (P. linteus) and red ginseng extracts on DNA damage induced by reactive oxygen species (ROS) were investigated in this study. P. linteus (PLE) and red ginseng extracts (RGE) inhibited the breaking of E. coli ColE1 plasmid DNA strands as well as nuclear DNA of rat hepatocytes damaged by oxidative stress. In addition, a reaction mixture of PLE and RGE showed synergistic inhibitory effect against DNA damage. These results suggest that PLE and RGE have a cellular defensive effect against DNA damage induced by ROS.

To produce the functional food materials from edible mushrooms, hot-water extracts from 70 kinds of mushroom mycelia were examined for anti-complementary activity and Phellinus linteus showed the highest activity through the complement fIxation test. The maximum production of Phellinus linteus mycelia with anti-complementary activity was observed in culture medium containing soluble starch 3.0%, peptone 0.3%, yeast extract 0.4%, $MgSO_4{\cdot}7H_2O$ 0.1%, $K_2HPO_4$ 0.2% and in the culture conditions controlled at initial pH 7.0, $30^{\circ}C$ and 150 rpm by the rotary shaker. In addition, the maximum production of mycelial dry weight was 15 mg/mL after 18 days under the optimal conditions, and anti-complementary activity was reached to 88% in 5 L-jar fermenter.

Pellinus linteus has been used for the prevention of cancer traditionally. There are three origins of Pellinus linteus, Korea, China and Cambodia. However, their immunological activities were not evlauated comparatively. Thus, this study was done to evaluate immunomodulatory effects of Phellinus linteus(PL) from Korea, china and cambodia, We confirmed PL showed two major protein bands, 50 kDa and 80 kDa by protein analysis. These PL effectively upregulated the expressions of IL-2 at 10 ug/ml and GM-CSF, IL-4, IL-10, IL-12(p35), IL-12(p40), IL-18, IFN-r in all concentrations. However, Korea-PL upregulated the expression of IL-12 more effectively than the other PLs. It intended to increase NO with no significance. Those results indicate Phellinus linteus had cytokine modulating effect

Various Phellinus species (Hymenochaetaceae) including P. linteus, P. baumii, P. pini, and P. igniarius of domestic and foreign products, were examined by gas chromatography to validate their composition of crude polysaccharides. The crude polysaccharide fraction, which is known to be one of the physiologically active fractions, were prepared by a cold ethanol precipitation method and the yield of the crude polysaccharide fractions of P. linteus, P. baumii, P. pini, and P. igniarius were 15.0%, 5.1%, 6.3% and 5.7%, respectively. The total monosaccharide amount of the crude polysaccharide fraction of P. linteus was 148.713 mg/g (dry weight of mushroom) while those of P. baumii, P. pini and P. igniarius were 29.022 mg/g, 29.222 mg/g and 1.546 mg/g, respectively. Although the major monosaccharide of all Phellinus mushrooms was glucose, there were remarkable differences in the absolute quantity of each monosaccharide. P. linteus included plenty of monosaccharides except mannose and ribose in comparison with P. baumii and P. pini. The absolute quantities of monosaccharides of P. baumii and P. pini were nearly similar except arabinose. The total monosaccharides of P. igniarius were minimal, but the portions of galactose and mannose in P. igniarius were greater than in the other species.

In order to increase the mycelial production of Phellinus linteus, which exhibits potent anticancer activity, some ingredients of the medium used to culture P. linteus were investigated. The optimal medium composition for the production of Phellinus linteus was determined to be as follows: fructose, 40 g/l; yeast extract, 20 g/l; $K_2HPO_4$, 0.46 g/l; $K_2HPO_4$, 1.00 g/l; M$MgSO_4\cdot7H_2SO$, 0.50 g/l; $FeCl_2\cdot6_2O$, 0.01 g/l; $MnCl_2\cdot4H_2O$, 0.036 g/l; $ZnCl_2$, 0.03 g/l; and $SuSO_4\cdot7H_2O$, 0.005 g/l. The optimal culture conditions were determined to be as follows: temperature, 28$^{\circ}C$; initial pH, 5.5; aeration, 0.6 vvm; and agitation, 100 rpm, respectively. Under optimal composition and conditions, the maximum mycelial biomass achieved in a 5 l jar fermentor was 29.9 g/l.

The objective of this study was to evaluate the bifidogenic effect and a-glucosidase inhibitory effect of artificially cultured Phellinus linteus. The water extract of P. linteus promoted the growth of Bifidobacterium breve as well as the decrease of final pH in the media culturing intestinal bacteria. The growth of lactic acid bacteria inhibited effectively the bacterial enzymes, ${\beta}-glucosidase,\;{\beta}-glucuronidase$ and tryptophanase, of intestinal bactetria. The water extract of P. linteus inhibited maltase, sucrase and ${\alpha}-amylase$ of rat intestine.

To develop a potent anti-obesity lipase inhibitor from mushroom, the lipase inhibitory activities of various mushroom extracts were determined. Methanol extracts from Phellinus linteus fruiting body exhibited the highest lipase inhibitory activity (72.8%). The inhibitor was maximally extracted by treatment of a P. linteus fruiting body with 80% methanol at $40^{\circ}C$ for 24 hr. After partial purification by systematic solvent extraction, the inhibitor was stable in the range of $40\sim80^{\circ}C$ and pH 2.0~9.0. In addition to lipase inhibitory activity, the inhibitor showed 59.4% of superoxide dismutase-like activity and 56.3% of acetylcholinesterase inhibitory activity.
