The purpose of this study was to investigate the possibility of Inonotus obliquus as an functional resource. To assess the effects of Inonotus obliquus in culturing method by using unpolished rice in 15non-insulin dependent diabetes mellitus persons, we examined changes of hematological and chemical variables, DM indices content in serum during the Inonotus obliquus supplementation. GOT, GPT concentrations were significantly decreased. But TIBC content was significantly increased. Fasting glucose level during Inonotus obliquus supplementation was decreased respectively. These results show that modest dose of Inonotus obliquus in culturing method by using unpolished rice supplementation can decrease fasting blood glucose level without any changes in health indices and nutrition status of the non-insulin dependent diabetes mellitus person. These results indicated that Inonotus obliquus in culturing method by using unpolished rice diet is effective therapeutic regimen for the control of metabolic derangements in diabetes mellitus. Also, the results imply that Inonotus obliquus in culturing method by using unpolished rice can be used as possible functional food materials. However, large amounts of Inonotus obliquus in culturing method by using unpolished rice showed be used cautiously application.

Inonotus obliquus is a traditional medicine mushroom that was developed from traditional medicine originating in ancient. It has been applied for cancer or immunotherapy, but its effect on pulmonary tuberculosis is not reported. Therefore, we measured the pulmonary tuberculosis therapeutic effect of methyl alcohol extract from MGIT 960 system with fluorescent indicator. Inonotus obliquus extract showed 14 day more inhibitory activity than the positive control. In addition, the anti-pulmonary tuberculosis activity of Inonotus obliquus was $50{\mu}m$. These results suggest that Inonotus obliquus methyl alcohol extracts could contribute to inhibition of pulmonary tuberculosis.

The antioxidant and anticancer activities of Phellinus linteus, Inonotus obliquus, and Pleurotus ostreatus according to extraction methods were measured. The contents of polyphenolic compounds were higher in fermented extracts than those in water extracts. The contents were 192.4mg/100 $m{\ell}$ for Inonotus obliquus vinegar, 186.9 mg/100 $m{\ell}$ for Phellinus linteus vinegar, and 156.5 mg/100 $m{\ell}$ for Pleurotus ostreatus vinegar, respectively. EDA(electron donating ability) in Phellinus linteus that was highest among mushrooms was 83.9% in the water extract and 96.8% in the fermented extract. The growth of stomach cancer cells, SNU-719 was inhibited 62.4%, 65.5%, and 53.0% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, respectively and also the growth of liver cancer cells, Hep3B was inhibited 67.1%, 68.3%, and 57.6% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, while the growth of normal cell, DC2.4 was not affected. Even though Phellinus linteus and Inonotus obliquus showed higher inhibition in cancer cell growth, Pleurotus ostreatus can be efficiently used for antioxidant and anticancer activities due to their cheap price in the market.

In order to investigate the possibility of Inonotus obliquus extract as an active ingredient for wrinkle-care cosmetics, we prepared 70 % ethanolic extract of Inonotus obliquus and measured its DPPH radical scavenging activity and elastase inhibitory activity. We also evaluated the effect of Inonotus obliquus extract on expression of MMPs and HAS-2 in fibroblast and HaCaT cell, respectively. Inonotus Obliquus extract showed DPPH radical scavenging activity and elastase inhibitory activity in a dose-dependant manner ($SC_{50}$ = 91 ${\mu}g$/mL, $IC_{50}$=124 ${\mu}g$/mL). Inonotus obliquus extract inhibited the expression of MMP-1 mRNA 50 ~ 79 % at concentrations of 5 ~ 25 ${\mu}g$/mL, and reduced the expression of MMP-2 around 20 % at a concentration of 10 ${\mu}g$/mL. And it also reduced the expression of MMP-9 54 ~ 70 % in tconcentrations of 5 to 25 ${\mu}g$/mL. Furthermore, Inonotus obliquus extract increased HAS-2 mRNA expression in a dose-dependent manner in concentrations of 5 to 25 ${\mu}g$/mL without cytotoxicity. These results suggested that Inonotus Obliquus extract could be useful as an active ingredient for wrinkle-care cosmetics.

Inonotus obliquus is a medicinal mushroom with a variety of biological activities. It has reported to have strong anti-cancer, antioxidant and anti-inflammatory properties. EBV+ gastric carcinoma is one of the most common EBV-associated cancers that were caused by latent EBV infection. In this study, we investigated the anti-cancer effects of ethanol extract of I. obliquus using in vivo xenograft animal models implanted with EBV+ human gastric carcinoma (SNU719). We also explored the molecular mechanisms responsible for its anti-cancer activity. The result indicated that the extract of I. obliquus had an anti-cancer effect in in vivo xenograft mice with EBV+ gastric carcinoma (SNU719). Extract of I. obliquus also showed a great effect on inducing the expression of p53, p21 and Bax in tumor tissue derived from EBV+ human gastric carcinoma, and these were correlated with increased expressions of the cleaved forms of caspase-9 and Parp. Also, I. obliquus attenuated the expression of viral proteins, BZLF-1 and LMP-2 in tumor tissue from EBV+ human gastric carcinoma.
