  • This study was carried out to identify medicinal mushrooms with protective effects against oxidative stress in PC12 neuronal cell line, followed by evaluation of their antioxidant property. Extracts of medicinal mushrooms, including Ganoderma lucidum extract (GLE), antler-shaped Ganoderma lingzhi extract (AGLE), Hericium erinaceus extract (HEE), and Sanghuangporus baumii extract (SBE), were screened for cytotoxicity using MTT assay. None of the extracts up to $10{\mu}g/ml$ concentration affected cell viability. These extracts were further checked for their protective effect against oxidative stress-induced reactive oxygen species (ROS) production. Exposure to $50{\mu}M$ $H_2O_2$ induced ROS generation in PC12 cells, which was inhibited only by treatment with AGLE. In addition, inhibition of $H_2O_2-induced$ ROS generation by AGLE was found to be in a dose-dependent manner (2.5, 5, and $10{\mu}g/ml$). Microscopic examination of DCF fluorescence for detection of ROS showed a similar pattern. Further, antioxidant activity of AGLE was determined by ABTS radical cation assay, and its $IC_{50}$ was found to be $46.90{\pm}0.31{\mu}g/ml$. Taken together, these results suggest that AGLE may help to alleviate oxidative stress in PC12 neuronal cells.

  • Oxidative stress is considered to play an important role in a variety of neurodegenerative disorders of central nervous system. The immortalized mouse hippocampal cell line, HT22, phenotypically resembles neuronal precursor cells but lacks functional ionotropic glutamate receptors, thus excluding excitotoxicity as a cause for glutamate triggered cell death. Therefore, HT22 cells are a useful model for studying oxidative glutamate toxicity. In this study, we examined whether the methanol extracts of some native plants at Mt. Baekdu could protect HT22-immortalized hippocampal cells against glutamate-induced oxidative stress. Seventy-eight plants sources were collected at Mt. Baekdu, and extracted with methanol. These extracts had been screened the protective effects against glutamate-induced oxidative damage in HT22 cells at the 100 and 300 ${\mu}g/ml$. Of these, thirteen methanolic extracts, Acer mono (leaf), Artemisia stolonifera (aerial part), Carduus crispus (aerial part), Carex mongolica (whole plant), Clematis hexapetala (whole plant), Galeopsis bifida (aerial part), Galium verum (whole plant), Ganoderma lucidum (whole plant), Ixeris chinensis (whole plant), Malva verticillata (aerial part), Polygonum senticosum (whole plant), Rebes mandshricum (branch), and Taraxacum mongolicum (aerial part), showed significant protective effects against glutamate-induced oxidative damage in HT22 cells.

  • For the utilization of Korean ginseng (Panax ginseng C.A. Meyer) in the functional drink, we prepared the fermented Korean ginseng with mushroom mycelia (Ganoderma lucidum; WG-GL, Hericium erinaceum; WG-HE and Phellinus linteus; WG-PL) by solid culture. A proximate analysis showed that the fermented Korean ginseng contained significantly more crude fat (4.66$\sim$12.02%) than Korean ginseng (WG, 1.61%) whereas crude protein content of WG (13.64%) was higher value than those of the ferments (7.60$\sim$12.57%). When we also evaluated effects of the fermented Korean ginseng on the mitogenic activity, hot-water extract from WG-PL was significantly higher than those of WG or mycelia only fermentation (GL, HE and PL) as analyzed by IL-2 production (1.64-fold of the saline control) and proliferation of splenocytes (1.47-fold). In addition, the lysosomal phosphatase activity (WG-HE; 1.32-fold) and NO/TNF-$\alpha$ production (WG-HE; 2.27-fold of the saline control at 50 ${\mu}g$/mL, WG-PL; 3.56-fold, respectively) from macrophage in the presence of the fermented Korean ginseng were higher than those of WG or mycelia fermentation. These results indicate that hot-water extracts from the fermented Korean ginseng with mushroom mycelia by solid culture contain chemical ingredients different from the Korean ginseng, and that it might provide beneficial immunostimulating activity.

  • To develop new therapeutic materials to prevent hair loss and enhance hair growth, we developed a medicinal herbal complex extract (MHCE) using 23 herbs traditionally used in oriental medicine. Medicinal Herbal complex extract was consist of Angelica gigas Nakai, Psoralea corylifolia Linne, Biota orientalis Endlicher, and Eclipta prostrata Linne, Rehmannia glutinosa Liboschitz var. purpurea Makino, Ligustrum lucidum Aiton, Polygonum multiflorum Thunberg, and Sesamum indicum Linne, Sophora angustifolia Sieboldet Zuccarini, Angelica dahurica Benthamet Hooker, and Leonurus sibiricus Linne, Salvia miltiorrhiza Bunge, Prunus persica Batsch, Commiphora molmol Engler, Chrysanthemum indicum Linne, Boswellia carterii Birdwood, Panax ginseng C. A. Meyer, Cnidium officinale Makino, Albizia julibrissin Durazzini, and Corydalis ternata Nakai that have traditionally been used for treating hair loss, preventing gray hair, anti-inflammation, and blood circulation in oriental medicine. In addition, we examined the hair growth effect of MHCE in vitro and in vivo. In vitro, we evaluated the effects of MHCE on cultured HFDPC, HaCaT cells, and murine embryonal fibroblasts (NIH3T3 cells). Also, we evaluated the ability of MHCE to prevent gray hair on murine melanoma cells (B16F1 cells). The hair growth-promoting effect of MHCE in vitro was also observed in vivo using C57BL/6 mice. Our results showed that MHCE significantly increased the proliferation of HFDPC (175 % proliferation at $50{\mu}g/mL$), HaCaT cells (133 % proliferation at $20{\mu}g/mL$), and NIH3T3 cells (120 % proliferation at $50{\mu}g/mL$). MHCE also showed consistent melanogenesis in B16F1 cells (154 % melanin synthesis at $50{\mu}g/mL$). Moreover, MHCE showed potential for hair growth stimulation in C57BL/6 mice experiments (98 % hair growth area on 4 weeks). These results indicate that MHCE may be a good candidate for promotion of hair growth.

  • This study was carried out to investigate the effect of fermented herbal mixtures (FHMs) in HepG2 and PC12 cells. Two different types of fermented herbal mixtures consisted of Chrysanthemum morifolium, Ganoderma lucidum, Acanthopanax senticosus, Schisandra chinensis, Hovenia dulcis thumb, and Lycii fructus. FHM-A and FHM-B were separately fermented with Prunellae Spica, Portulaca oleracea (FHM-A) and Acorus gramineus, Pycnostelma paniculatum (FHM-B). Total phenolic content of FHM-B was higher than that of FHM-A. ORAC values in both FHM-A and FHM-B increased in a dose-dependent manner, and antioxidant activities against peroxyl radicals were higher in FHM-A than FHM-B. Both FHM-A and FHM-B effectively ameliorated AAPH- and ethanol-induced oxidative stress in HepG2 cells. They also suppressed lipid formation induced by ethanol treatment. In addition, FHM-A and FHM-B prevented $H_2O_2$-induced PC12 cell death. FHM-B showed a relatively stronger protective effect than that of FMB-A. Taken together, these findings show that a fermented herbal mixture could be used in healthy and functional food design for oxidative stress-related diseases.

  • The antioxidant and anticancer effects of the edible mushrooms Lentinus edodes (LE, Pyogo mushroom) and Agaricus blazei (AB, Agaricus mushroom), and the medicinal mushrooms Cordyceps militaris (CM, Dong chunghacho), Ganoderma lucidum (GL, Youngji mushroom), Inonotus obliquus (IO, Chaga mushroom), and Phellinus linteus (PL, Sangwhang mushroom) were studied in vitro. The bioactive components were extracted by methanol. The antioxidant effects were evaluated using the DPPH and hydroxyl radical scavenging assays. The antioxidant activities of medicinal mushrooms (35~90%) were higher than edible mushrooms (4~23%). The in vitro anticancer effects of the mushrooms were evaluated using the MTT assay in AGS gastric adenocarcinoma cells, HCT-116 colon carcinoma cells, and HepG2 hepatoma cells. The medicinal mushrooms CM, GL, IO, and PL showed 28~91% inhibition, while the edible mushrooms LE and AB exhibited 5~40% inhibition. The medicinal mushrooms, compared to edible mushrooms, effectively down-regulated the gene expression of the anti-apoptosis related gene Bcl-2 and inflammation-related genes iNOS and COX-2, and up-regulated the pro-apoptosis gene Bax (p<0.05). Total polyphenol and flavonoids contents of the medicinal mushrooms were 9.1~35.7 mg/g, while the edible mushrooms showed 0~13.3 mg/g. This study showed that antioxidant activities and anticancer activities in vitro increased in the order LE, AB, GL, CM, IO and PL. LE and AB showed the lowest effects among the samples, GL and CM had medium effects, and IO and PL exhibited the highest effects in the antioxidant and anticancer effect for three different human cancer cells. Taken together, PL resulted in the highest and LE the lowest effects in this study.

  • This study was carried out to improve standardization of agricultural products and investigate quality changes during preservation at various treatments. The standardization does much to improve merchantable quality, distribution efficiency and fair dealings by shipping of the standard agricultural products. Mushrooms notified as the standard are five; Pleurotus ostreatus, Pleurotus eryngii, Flammulina velutipes, Agaricus bisporus and Ganoderma lucidum. But many farmers are suffering from strict standards. Therefore, modification of these standards is required to fit farmhouse situations. Fruit-body weight of A, B and C grades of the marketed Agaricus bisporus was 19.3g, 12.2g and 10.4, respectively. Average pileus diameter of A grades was 43.3mm but B and C grades did not show significant difference. Average stipe length of A, B and C grades was 9.8mm, 13.1mm and 11.6mm, and stipes thick was the highest in A grades. The weight loss rate of stipe cutting of Agaricus bisporus was 12.6% in harvested mushrooms and the rate of stipe cutting length was 60.8%. The diameter of Agaricus bisporus stored for 5 days was 3.5~4.5cm but decreased rapidly in 15 days. The weight loss rate of the high temperature samples lowered rapidly than that of the low temperature samples. Conversely, the L value of the low temperature samples was higher than that of the high temperature samples.

  • Podostroma cornu-damae is a rare species of fungus belonging to the Hyocreaceae family. Its fruit body is highly toxic, as it contains trichothecene mycotoxins. The morphology is similar to that of immature Ganoderma lucidum, making identification difficult for non-experts. We experienced such a case of a 56- year-old male who picked and consumed podostroma cornu-damae, and consumed. Later that day, he developed digestive system symptoms, including nausea, vomiting, and abdominal pain. He presented to the emergency room (ER), there were no abnormal physical findings, symptoms improved after gastric lavage, and the patient voluntarily discharged himself on the same day. The following day, as the symptoms gradually deteriorated, he was admitted via the ER. He was presented with severe pancytopenia, alopecia, desquamation of skin, and acute renal failure. He recovered without any complications after conservative care, antibiotics therapy, and granulocyte colony stimulating factor administration. The most commonly reported complications of podostroma cornu-damae intoxication were reported pancytopenia, infection, disseminated intravascular coagulation, acute renal failure, etc. since Prevention is especially important because its toxicity can be lethal and there is no particular treatment to date, prevention is especially important. Promotion and education for the public are needed.
