  • Mushroom mycelia-cultured traditional meju (MTM) was prepared by inoculating 10% submerged-liquid culture of mushroom strains to five holes (1$\times$3 cm) per side of the traditionally-fermented meiu (10$\times$10$\times$10cm), followed by incubating additional 4 weeks at $25^{\circ}C$. Mushroom strains used were Neutari (Pleurotus ostreatus, PO), Yeongji (Ganoderma lucidum, GL), Synryeong (Agaricus blazei, AB), Ypsae (Grifola frondosa, GF), Pyogo(Lentinus edodes, PE), Dongchunghacho (Paecilomyces japonicus, PJ) and Sanghwang (Phellinus linteus PL). All MTMs showed an enhanced anticarcinogenicity against S-180 cell-induced mouse ascites cancer antimutagenicity against aflatoxin B$_1$ (AFB$_1$) and 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), and sensory qualities, relative to control meju. Such positive effects of MTM prepared with Sanghwang, Yeongji, or Synryeong were superior to those of MTM with Ypsae, Pyogo, Dongchunghacho, or Neutari.

  • Eight edible mushrooms grown in Korea were extracted with ethanol at room temperature for 24 hr. The extracts were investigated for their antioxidant activities as measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation scavenging activities. Among the mushroom extracts evaluated in this study, the ethanolic extracts from Ganoderma lucidum and Pleurotus eryngii showed the greatest potential antioxidant activity, by producing 85 and 88% inhibition in DPPH radical scavenging method and 219 and 165 mg ascorbic acid equivalent antioxidant capacity (AEAC), respectively. Total phenolics and total flavonoids in the ethanolic extracts were determined by spectrophotometric method. Positive correlations were found between total phenolic contents in the extracts and their antioxidant activities, suggesting that phenolic contents in the mushrooms extracts are mainly responsible for their antioxidant activities.

  • G009, a polysaccharide isolated from the mycelia of Ganoderma lucidum IYO09, showed a hepatoprotective activity against $CCl_4$ induced cytotoxicity in primary cu ltured rat hepatocytes. Incubation of $CCl_4$-intoxicated hepatocytes with G009 significantly reduced the levels of glutamic pyruvic transaminase and sorbitol dehydrogenase released from hepatocytes in the medium. G009 showed antioxidative effect by elevating the activities of glutathione reductase and superoxide dismutase, and the content of glutathione in $CCl_4$-intoxidcated primary cultured rat hepatocytes. Furthermore, G009 significantly elevated glutathione-S-transferase activity in $CCl_4$-intoxicated primary cultured rat hepatocytes. G009 also reduced the production of malondialdehyde, a byproduct of lipid peroxidation. From these results, it could be concluded that G009 exerted hepatoprotective activity against $CCl_4$-induced cytotoxicity through antioxidation.

  • Ganoderan (GAN), an immunomodulating ${\beta}-glucan$ of G. lucidum, induces potent antitumor immunity in tumor-bearing mice. This study was set up to elucidate the ability of macrophage activation of GANs. GAN-treated Raw 264.7 macrophages showed enhanced production of nitric oxide (NO). The ability of GANs to produce NO was based on differences in chemical composition of GANs obtained from the mycelium on various carbon sources and mycelial fractionation. The highest NO production was observed in CW-AS-WS polysaccharide which was extracted from the mycelial wall. GAN-treated Raw 264.7 cells gave a 2-to 5-fold (24 hr) formation of NO levels compared with those treated with medium only. Partial removal of the protein in the extracellular GAN by TCA treatment did appreciably reduce its capacity to secrete NO. The mixture effect of GAN and LPS increased the nitric oxide secretion from RAW 264.7. The cell proliferation of GAN-treated Raw 264.7 cell tines inhibited as compared with its control. Of the culture supernatant of macrophage activated by GAN, the percentage of cytotoxicity against mouse leukemia L1210 cells was slightly dependent on the amount of NO in the culture supernatants of the activated-macrophages. These results indicate that the ${\beta}-glucan-related$ polysaccharides of the higher fungus activate macrophage and release nitric oxide. It also suggests that murine macrophages possess certain receptors for ${\beta}-anomeric$ glucans and play a critical role of ${\beta}-glucan-related$ tumor killing mechanism.

  • Three mushroom mycelia, Ganoderma lucidum, Hericium erinaceum, and Phellinus linteus, were separately diluted with the natural culture media Acanthopanax senticosus. Solid-state fermentation was used to produce three different A. senticosus-fermented mushroom mycelium groups: G. lucidum mycelia, H. erinaceum mycelia, and P. linteus mycelia. The resulting mycelia were analyzed to assess their efficacies as health functional foods. Optimized fermentation conditions were determined by considering the density and growth speed of mycelia in each A. senticosus-fermented mushroom mycelium group. The cultured mushroom mycelia under the optimized conditions were extracted using water and 70% ethanol. Extraction was followed by filtration, concentration and freeze-drying to produce extract powder of A. senticosus-fermented mushroom mycelia: Water extracts (FM-5111, FM-5121, and FM-5131) and 70% ethanol extracts (FM-5112, FM-5122, and FM-5132). Analysis of extract powder of A. senticosus-fermented mushroom mycelia was performed using the maker compounds eleutheroside B and eleutheroside E. Analysis of ${\beta}$-glucan contents was performed by enzymatic procedures.

  • The antioxidative effects of fermented milk, mushroom extract and fermented milk containing its extract (Lentinus edodes, Ganoderna lucidum, and Pleurotus ostreatus) on the lipid peroxidation in the tissues of female Sprague-Dawley rats and on the DPPH ($\alpha,\alpha$' -diphenyl-$\beta$-picrylhydrazyl) radical donating ability were studied. The total concentrations of polyphenolic compound in Lentinus edodes, Ganoderma lucidum and Pleurotus ostreatus were 0.34, 0.20 and 0.34%, respectively. The DPPH donating abilities of mushroom extract, fermented milk, fermented milk containing its extract and BHT (butylated hydorxytoluene) as standard were 33.9, 34.9, 51.9 and 95.6%, respectively. Experimental diet groups were divided into five groups: the normal diet (ND), the cholesterol diet (CD), and cholesterol + fermented milk diet (CDFM), cholesterol + mushroom extract diet (CDME) and cholesterol + fermented milk containing mushroom extract diet (CDFMME). The concentrations of lipid peroxide in liver and its microsome were significantly lower in both CDFM and CDFMME groups than in the other groups. The kidney concentration of lipid peroxide was significantly higher in the CD group than in the ND group, but this rise were significantly decreased in the CDFM and CDFMME groups. Meanwhile, the concentrations of heart and spleen and their fractions were not significantly different among dietary groups. This study was suggested that the fermented milk diet containing mushroom extract effectively reduced the lipid peroxidation in liver and kidney of cholesterol-fed female rats.
