Complex of mulberry extract (CME) is composed of extracts of mulberry (Morus alba L.) fruit, mulberry leaves and black beans (Glycine max (L.) Merr.). In this study, we investigated prevention effects of CME on degenerative arthritis. The $SC_{50}$ value of DPPH radical scavenging by CME was $158.49{\pm}11.35{\mu}/mL$. We found that CME significantly reduced the production of nitric oxide (NO) and protein expression of cyclooxygenase-2 (COX-2) in RAW 264.7 cells which were activated by LPS. Experiments using animal model of degenerative arthritis showed that CME (400 mg/kg body weight) inhibited the production of TNF-${\alpha}$ (77.5%) and IL-$1{\beta}$ (95.0%). Furthermore, it was observed that CME reduced to 85.9% of paw edema induced by carrageenan. These results suggest that CME could improve degenerative arthritis.

Three ergosterol derivatives, ergosta-4,6,8(14),22-tetraen-3-one (1), ergosta-7,24(28)-dien-3-ol (2), and 5,8-epidioxyergosta-6,22-dien-3-ol(3) were isolated from the fruit body of Phellinus pini. Their structures were based on spectroscopic methods including IR, MS, and NMR (1D and 2D). These compounds were evaluated for their activity to decrease melanin production in ${\alpha}$-MSH (melanocyte stimulating hormone) activated B16F10 cells. Compound 1, 2, and 3 reduced melanin content in a dose-dependent manner at concentrations of 5~15 uM. They also suppressed the tyrosinase expression of protein and m-RNA level dose dependently by western blot analysis and RT-PCR experiment in B16F10 murine melanoma cells.

The aim of this study was to investigate the effect of fermented fruits (FF) on the growth performance, Enterobacteriaceae and Lactobacillus counts in faeces of the post-weaning piglets. A total of twenty-four 4 weeks old Landrace${\times}$ Large White${\times}$Duroc with initial body weight of 6 kg were used in this study. The piglets were housed individually in metabolic cage and randomly assigned to four groups with six piglets per group. The piglets were fed on basal diet without antibiotic (AF), basal diets with antibiotic (Ab), basal diet with 10% (w/w) fermented fruit (10% FF) and basal diet with 20% (w/w) fermented fruit (20% FF). Faecal samples were taken directly from the rectum of each piglet and cultured for Enterobacteriaceae and Lactobacillus counts. In the growth performance, the piglets of Ab and 10%FF had significantly higher (p<0.05) average daily gain than those of 20%FF. However, no differences (p>0.05) were observed between AF, Ab and 10%FF. Studies showed that the use of fermented fruits (FF) could significantly (p<0.05) reduce Enterobacteriaceae population in piglets' faeces compared to the use of normal feed (AF) and antibiotic (Ab). However, the Lactobacillus population in the faeces was increased in those piglets fed with diets added with FF.

The anti-inflammatory activity of fruit body of Phellinus pini was investigated by activity-guided fractionation. From the screening of each fraction for the inhibitory activity of NO production in lipopolysaccaride (LPS) activated RAW 264.7 cells, methanol extract and its hexane soluble fraction of Phellinus pini exhibited inhibition of NO production compared with LPS control without toxicity. The hexane soluble fraction showed dose-dependent inhibition of NO production. The active hexane fraction was repeatedly chromatographed over silica gel, ergosta-7,24(28)-dien-3-ol(1) and ergosterol peroxide (2) were isolated and identified. Ergosterol derivatives were inhibited NOS activation, $IC_{50}$ of them were $18.9{\pm}3.9{\mu}M$ (1) and $20.4{\pm}4.5{\mu}M$ (2).

The objective of the current study was to determine the effects of the crude polysaccharide isolated from fruit body of Pleurotus eryngii on mouse splenocytes, B cells, and macrophages in vitro. The crude polysaccharides directly induced the proliferation of spleen cells in a dose-dependent manner and increased IL-6 and IFN-${\gamma}$ synthesis. The crude polysaccharides also increased the proliferation of B cells in a dose-dependent manner. The production of immunoglobulin Gl, G2a and IgG3 in the presence of the crude polysaccharides was increased progressively in the culture supernatant. When the crude polysaccharide were used in macrophage cell line (RA W264.7) stimulation, there were marked induction of NO synthesis in a dose-dependent manner and IL-6, TNF- r and GM-CSF synthesis. These results suggest that the crude polysaccharide isolated from fruit body of Pleurotus eryngii seem to act as a potent immunomodulator causing augmentation of immune cell activity, and thus could be used as a biological response modifier having possible therapeutic effects against immunological disorders, without any side effects.

'Heukhyang', a new variety with dark brown color, short cultivaltion period, and good taste in Flammulina velutipes, was bred by crossing between monokaryons isolated from 'Garlmoe' and wild strain 'CBMFV-10'. In bottle cultivation, the period of mycelial growth, primordia1 formation, and growth of fruit body was required 23 days, 6 days, and 17 days, respectively. Total culvivation period was 46 days, showing 8 days shorter than that of 'Garlmoe'. Pileus diameter and thickness were greater than those of 'Garlmoe', and pileus color showed dark brown. Fruit body production per 850 ml bottle was 135 g, which was 10% lower than that of 'Garlmoe'. However, the overall acceptance was most excellent in sensory evaluation, and 'Heukhyang' has an advantage to target a niche market of white ones due to differentiated color and taste.

'Geumhyang', a new variety with short cultivation period and yellowish ivory color in Flammulina velutipes, was bred by crossing between monokaryons isolated from 'Garlmoe' and wild strain 'CBMFV-33'. In bottle cultivation, the period of mycelial growth, primordia1 formation, and growth of fruit body was required 23 days, 7 days, and 17 days, respectively. Total culvivation period was 47 days, showing 7 days shorter than that of 'Garlmoe'. Pileus diameter was greater than that of 'Garlmoe', and pileus color showed yellowish ivory. Fruit body production per 850 ml bottle was 160 g, which was 8% higher than that of 'Garlmoe'. The taste, derived from 'Garlmoe' and wild strain, was excellent because of better chewing feeling than white ones. 'Geumhyang' with differentiated color and taste, has an advantage to target a niche market of white ones.

Prolonged alcohol consumption causes alcoholic liver damage due to the generation of reactive oxygen species, the accumulation of fatty acids, and an increase in inflammatory cytokines in the liver. In this study, the protective effect of a fruit extract of Paeonia anomala (FEPA) against chronic alcohol-induced liver damage was evaluated in Sprague-Dawley rats fed an ethanol or a control Lieber-DeCarli diet for 5 weeks to induce alcoholic liver damage. FEPA (50, 25, and 10 mg/kg body weight/day) as well as the reference control silymarin (25 mg/kg body weight/day) were administered along with the ethanol diet. FEPA protected against increases in alanine aminotransferase and aspartate aminotransferase in serum and attenuated alcohol-induced increases in triglycerides, tumor necrosis factor alpha, thiobarbituric acid-reactive substances, and cytochrome P450 2E1 enzyme activity in the liver compared with the group treated with ethanol only. Anti-oxidative defenses such as the total glutathione level and glutathione peroxidase activity were increased by FEPA treatment. These results suggest that FEPA exerts protective effects against chronic alcohol-induced liver damage by attenuating hepatosteatosis and pro-inflammatory cytokine production and enhancing anti-oxidative defense mechanisms in the liver.

This study was conducted to investigate the characteristics and biological activities of the substance extracted from the fruit body of Formitopsis rosea. The substance was extracted by hot water and then it was separated high and low molecular weight fraction by ethanol precipitation, The high molecular weight fraction was found to be a proteoglycan composed of glucose, mannose, galactose, xylose, fructose, ribose and amino acids. The amino acids of proteoglycan were mainly threonine, isoleucine, glycine, aspartic acid. Anticomplementary activity of the high molecular weight fraction was higher than that of the low molecular weight fraction. And also, the high molecular weight fraction enhanced phagocytic activity and nitric oxide production of macrophage. In enzymatic lipid peroxidation reaction with $ADP-FeCl_3-NADPH$, the lipid peroxidation was inhibited 82.4% and 86.6% by high and low molecular weight fractions, in nonenzymatic lipid peroxidation reaction, it was 83.0% and 84.6%, respectively.
