This study was designed to develop functional drink from jujube extract through a simple submerged culture of three basidiomycetes species. The optimum Brix and pH of the jujube extract for culturing the Ganoderma lucidum appeared to be 5 Brix and pH 4. Ten days of culture period produced maximum mycelium. The optimum Brix and pH of the jujube extract for culturing the Coriolus versicolor appeared to be 5 Brix and pH 5. Ten days of culture period produced maximum mycelium. The optimum Brix and pH of the jujube extract for culturing the Phellinus igniarius appeared to be 3 Brix and pH 5. For the maximum mycelial production eighteen days of culture period was required for Phellinus igniarius. The antitumor activity of the polysaccharides extracted from the fermented drinks was demonstrated through the tumor cell line experiments. The $IC_{50}$ values of the jujube drinks fermented with Ganoderma lucidum and Phellinus igniarius against stomach cancer cell line appeared to be one fourth that of the jujube drink which was not fermented with basidiomycetes.

The anticoagulant polysaccharide was screened from the ediable mushrooms. Among them, alkali extract of Ganoderma lucidum showed the highest activity in aPTT. A crude polysaccharide fraction (GL-I) was prepared from the 1N NaOH solution extract of Ganoderma lucidum followed by methanol-reflux, precipitation with ethanol, dialysis and lyophilization. GL-I inhibited the intrinsic pathway in blood coagulation pathway and exhibited concentration dependent anticoagulation effects. The anticoagulant activity of GL-I was decreased greatly by periodate oxidation, but was not changed by pronase digestion. These suggest that carbohydrate moiety may be related to the anticoagulant activity. GL-I consisted of glucose, galactose, fucose, xylose, mannose, arabinose in a molar ratio of 19.3:3.0:2.3:1.3:1.0:0.3. GL-I was partially purified on the DEAE-Toyopearl 650C(GL-IalongrightarrowGL-If) and on the Sephadex G-100(GL-Ic-ilongrightarrowGL-Ic-II).

The purpose of this study was to develop functional breads added with Ganoderma lucidum (GL) extract which was well known for preventing various adult diseases and cancer. It was observed that bitter taste was increased with up to 8％ GL extract while dough volume was increased at the first dough fermentation period and baking loss reduction was decreased. In terms of sensory evaluation, there were not so much significant differences with 2％ added GL extract. In 4, 6, 8％ added GL extract bread, it was found that 4％ was ordinary and 6％ and 8％ were bad compared to the control bread. The bread with 2％ added GL extract was excellent, 4％ was ordinary and 6, 8％ was badly evaluated in the internal texture. It's possible to make the functional breads baking with 2％ GL extract which is similar to the control breads based on the above results.

The concentrations of bioactive material (polyphenolics and flavonoids) and the biological activities of antioxidative (DPPH [${\alpha},{\alpha}'$-diphenyl-${\beta}$-picrylhydrazyl] free radical scavenging activity, peroxidation of rat liver microsome, and Fe/Cu reducing power), ${\alpha}$-glucosidase inhibition, tyrosinase inhibition, and fibrinolytic activity were tested by in vitro experimental models using 70% methanolic extract from Ganoderma lucidum, Momordica charantia, Fagopyrum tataricum and their mixtures. The highest yield and the concentrations of polyphenolics and flavonoids were shown in the mixture extract. Mixture extract was shown to have the highest activities of ${\alpha}$-glucosidase inhibition and tyrosinase inhibition, fibrinolytic, DPPH free radical scavenging, and Fe/Cu reducing power in a concentration-dependent manner. From these results, mixture methanol extract was shown to have the most potent bioactive properties and to contain large amounts of biological materials such as polyphenolics and flavonoids. This mixture could be a good dietary supplement material candidate, such as for antidiabetic functional foods.

The effect of Ganoderma lucidum extract on Saccharomyces cerevisiae growth and physiology has been investigated. S. cerevisiae was inoculated in Henneberg solution medium into which 0, 0.1, 0.5 or 1.0% extracts of G. lucidum were added respectively and it was fermented at $30^{\circ}C$ for 5 days, respectively. Cell number of S. cerevisiae has increased according to the concentration as in order of distilled water(Dw) extracts 1.0% added>ethanol(Et) extracts 1.0% added>Dw extracts 0.5% added>Et extracts 0.5% added>Dw extracts 0.1% added>Et extracts 0.1% added group compared to control group(extracts 0% added) and in Dw extracts 1.0% added group the number has increased than those of control group after the fermentation of 72 hours. Weights of dried yeast cell have increased in each treated group than those of control group and it increased about 1.7 times in each Dw 1.0%, Et 1.0% group than those of control group after fermentation of 120 hours. The more the extracts of G. lucidum was added, the more alcohol levels increased during fermentation. The rate of carbon dioxide production per G. lucidum extract medium was faster than those of control group as G. lucidum extract was increasingly added.

This study investigated whether Ganoderma lucidum (Y2)-mediated fermentation of Artemisia capillaris extract (ACE) could synergistically enhance its antioxidant, anti-inflammatory, and tyrosinase-inhibiting activities. Both G. lucidum extract and fermented ACE exhibited 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability, but with poorer efficacy than ACE (even at a low ACE concentration). Viability of RAW264.7 macrophages was significantly reduced in the presence of ACE (150 mg/mL and above). However, this effect was greatly mitigated upon G. lucidum-mediated ACE fermentation. Additionally, relative to the same concentration ($25{\mu}g/mL$) of G. lucidum mycelial extract, ACE exhibited an improved ability to significantly inhibit RAW264.7 macrophage nitric oxide (NO) production. Finally, relative to the same concentration ($200{\mu}g/mL$) of a positive control (arbutin), fermented ACE exhibited an approximately 3.66 times higher capacity for tyrosinase inhibition. These results suggest that G. lucidum-fermented ACE possesses enhanced tyrosinase-inhibiting activity and may be of utility as a skin-lightening agent.

Objectives This study was carried out to investigate the effect of Ganoderma lucidum extract (GLE) and microneedle therapy system (MTS) on hair growth in an alopecia model of C57BL/6N mice. Methods Five-week old mice were depilated and separated in 4 groups ; CON (50% EtOH), MXD (5% Minoxidil), MTS and GLE + MTS. The treatments were applied twice a week for 3 weeks. The hair growth was determined photographically, the hair density, thickness and length were identified by Folliscope and the weights of body and organs were measured. In dorsal skin tissue, the expression of hair growth-related gene and protein was analyzed by RT - PCR or Western blot. In addition, the hair follicles in the dermis were observed by H&E staining. Results The promotion of hair growth was observed in GLE + MTS and MTS compared to CON. The hair density, thickness and length were also improved in GLE + MTS and MTS compared to CON. The mRNA expression of TGF-${\alpha}$, TGF-${\beta}1$, IGF-1, PRL and PL and the protein expression of VEGF and IGF-1 were increased in GLE + MTS and MTS compared to CON. The hair follicles and hair root growth were improved in GLE + MTS and MTS compared to CON. In the above results, GLE + MTS were more effective than MTS. Conclusions These results suggest that GLE and MTS has a hair growth activity and can be useful for the treatment of alopecia.

The cultured mycelial cells of Ganoderma lucidum was extracted by alkali, and then neutralized by acid. The extract was passed through the column of DEAE cellulose for more purification. The neutral fraction was concentrated and precipitated with 95% ethanol. The precipitate was lyophilized and then PSG(polysaccharides) was obtained. PSG was composed of 82.2% polysaccharide, 0.7% protein and 17.1% uronic acid. Sugar conjugates of its hydrolysates were produced using with fluorescent compound(7-amino-1,3-naphthalene disulfonic aicd : 7-AGA), and then fluorescent labeled sugar conjugates were separated by reverse phase high perfomance liquid chromatography. Hydrolysates of PSG were composed of sixteen amino acids and 95.7% glucose, 2.7% xylose, 1.6% fucose and tract amount of galactose and mannose. The immunomodulating effects of PSG on macrophage were perfomed using murine macrophage cell line ATCC TIB 71 cells. PSG augumented the phagocytic activity of TIB 71 cells against fluorescent latex beads.
