사람의 피부는 자외선, 오염된 공기, 화학 제품 등 환경에 끊임없이 노출된다. 이들로 인한 자유라디칼과 활성 산소는 피부세포에 큰 손상을 끼치게 된다. 캄보디안 상황버섯 열수, 에탄올 추출물의 기능성 화장품 소재로 활용하기 위하여 지방 산패 억제능 측정과 주름개선 효과 측정을 하였다. 캄보디안 상황버섯 열수, 에탄올 추출물에 금속이온을 첨가하여 지방산패 억제능을 측정한 결과 캄보디안 상황버섯 열수 추출물 보다 에탄올 추출물이 $Fe^{2+}$와 $Cu^{2+}$chelating 능력이 우수하였다. 캄보디안 상황버섯 에탄올 추출물의 경우 0.1 mg/ml, 0.5 mg/ml, 1 mg/ml의 농도에서 대조군인 butylated hydroxytoluene (BHT)보다 높은 지방산패 억제를 나타내었다. 캄보디안 상황버섯 열수, 에탄올 추출물은 산화 촉매제인 $Fe^2$를 함유한 지방 산패 억제능이 $Cu^{2+}$를 이용한 지방산패 억제능 보다 우수하였다. 주름개선 효과 측정으로 elastase 저해활성을 측정한 결과 캄보디안 상황버섯 에탄올 추출물은 0.01 mg/ml의 농도에서 50.7%의 저해활성을 나타내어, 대조군인 urosolic acid보다 높은 elastase 저해활성을 타나내었다. 또한 에탄올 추출물의 경우 0.1 mg/ml의 농도에서 약 50%의 저해활성을 나타내어 캄보디안 상황버섯 열수 추출물 보다 에탄올 추출물이 collagenase에 대해 높은 저해활성을 나타내었다. 이상의 결과에서 캄보디안 상황버섯의 에탄올 추출물은 지방산패 억제능이 우수할 뿐만 아니라 주름 개선 효과가 있음을 확인할 수 있었고, 주름 개선 화장품 소재로서의 가능성을 확인할 수 있었다.

In order to research the anti-oxidative activity of methanol extract of Phellinus baumii Pilat (Hymenochaetaceae), Caenorhabditis elegans model system was used. Ethyl acetate soluble fraction of the methanol extract showed the most potent DPPH radical scavenging activity. The ethyl acetate fraction was measured on its activities of superoxide dismutase (SOD), catalase, and oxidative stress tolerance with reactive oxygen species (ROS) level in C. elegans. Furthermore, to see if regulation of stress-response gene is responsible for the increased stress tolerance of C. elegans which treated by the ethyl acetate fraction, we checked SOD-3 expression using a transgenic strain. Consequently, the ethyl acetate fraction of P. baumii increased SOD and the catalase activities in a dose-dependent manner in C. elegans, reduced ROS accumulation dose-dependently. Besides, the ethyl acetate fraction-treated CF1553 worms showed higher SOD-3::GFP intensity than the control worms.

Phelligridin D (Phe D) is a compound isolated from Phellinus baumii, which is known for various biological activities. In this study, the authors examined the effect of Phe D on boar spermatozoa for its potential application in assisted reproductive technology for mammals. Sperm motility and deubiquitinylating activity significantly decreased when boar spermatozoa were incubated with Phe D (>$0.5{\mu}M$). The fluorescence intensities of dead sperm, and reactive oxygen species production increased after sperm incubation in the presence of Phe D. Although Phe D is associated with antioxidant and free radical scavenging activity, sperm viability deteriorated after its addition. This could lead to fertilization failure, including that following artificial insemination or in vitro fertilization. Phe D might have other biological functions in spermatozoa, and therefore requires additional studies in the future.

The investigation was made about distribution and ecological characteristics of host plant for Phellinus linteus at habitats in Gangwon-Do. The habitats of P. linteus are the place where the fog is much generated and there is lots of the moisture. The flora of the vascular plants in P. linteus habitats were consisted of 76 taxa; 62 species, 10 varieties and 4 formas of 62 genera of 40 families. The plants of infiltration type were found 70% around P. linteus habitats. This results shows that the natural environments of P. linteus habitat is very stable condition. The categories of vegetation were classified into two types. The host plant for P. linteus appeared 61.6% from Populus tomentiglandulosa. The first type showed up above the sea about 600m and west exposure region. The second type was investigated around the facing north region of the steep slope-land.

Studies on the chemical constituents from a Korean wild mushroom, Phellinus ribis, were carried out. A triterpenoid, two peroxysterols, and a chlorobenzene compound were isolated from the hexane soluble fraction of the methanol extract of dried fruiting bodies of the basidomycetes. Those compounds identifed were 3-hydroxy-20(29)-lupen-28-oic acid (betulinic acid), 5,8-epidioxyergosta-6,22-dien-3-ol(ergosterol peroxide), 5,8-epidioxyergosta-6,9(11),22-trien-3-ol (dehydroperoxyergosterol), and 1,2,4,5-tetrachloro-3,6-dimethoxybenzene. Structural studies were carried out on molecular species of a ceramide and cerebroside isolated from the chloroform soluble fraction of the methanol extract. For ceramide, the major component fatty acids were a-hydroxy fatty acid isomers of $C_{22:00}{\sim}C_{25:00};$ the predominant long-chain bases were trihydroxy sphinganine of $C_{17}{\sim}C_{18}$. The structure of a cerebroside containing mono-sugar was assumed that the long-chain base was $C_{19:2}$ sphingadienine; the major fatty acids were $C_{16}{\sim}C_{15}$ ${\alpha}$-hydroxy fatty acid isomers.

Davallialactone (DAVA) is a hispidin analogue derived from the medicinal fungus Phellinus baumii. We examined the effect of DAVA on in vitro fertilization (IVF) of pigs. Boar spermatozoa were incubated in fertilization medium with varying concentrations of DAVA, then sperm motility and reactive oxygen species (ROS) level were evaluated. Higher sperm motility was found following the addition of 0.5 or $1{\mu}M$ DAVA after incubation than addition of other concentrations or controls. ROS level decreased significantly with the addition of DAVA. The rate of normal fertilization was higher in the presence of $1{\mu}M$ DAVA (65.1%) than were those of other concentrations or controls (45.4~59.4%), and the highest total fertilization rate (mono- and polyspermic oocytes) was observed at $1{\mu}M$ DAVA (83%). In conclusion, addition of DAVA to fertilization medium improved sperm motility, and reduced ROS level so as to potentially improve sperm-oocyte binding in IVF, suggesting the potential of a compound isolated from mushrooms in assisted reproductive technology for humans and animals.
