Background: This study examined the use of new bio-materials with enhanced value and functionality, which were derived from fermented wild ginseng cultures. Methods and Results: To examine the antioxidant activity associated with biological functions, radical scavenging analyses (2,2-diphenyl-1-picrylhydrazyl, DPPH and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid, ABTS) and superoxide dismutase (SOD)-like activity analyses were conducted. Furthermore, the total phenolic and flavonoid contents of wild ginseng fermented with microorganisms (Leuconostoc mesenteroides, Bacillus circulans, Bacillus licheniformis and B. subtilis subsp. inaquosorum) were evaluated to determine the antioxidant activity increment. Regarding ginseng fermented with B. licheniformis, values of $70.6{\pm}1.4%$, $44.3{\pm}1.7%$, and $88.4{\pm}1.3%$ were measured using DPPH, ABTS, and SOD-like antioxdiant activity analyses, respectively. The total phenolic content in ginseng fermented with B. licheniformis was $184.5{\pm}0.9{\mu}g{\cdot}GAE/m{\ell}$, and the total flavonoid contents was $108.5{\pm}1.8{\mu}g{\cdot}QE/m{\ell}$ in ginseng fermented with L. mesenteroides. Conclusions: Of the four types of lactic acid bacteria examined, the use of B. licheniformis to ferment ginseng resulted in greatest increase in antioxidant activity. Therefore, ginseng fermented by microorganisms might be used to produce functional bio-materials.
Objectives : This study aimed to evaluate the protective effect of Orostachydis Herba (OH) and Fermented OH (OHF) against the acute liver injury by lipopolysaccharide (LPS). Methods : OHF by 4 lactic bacteria such as (Lactobacillus hilgardii (OHF1), Leuconostoc mesenteroides (OHF2), Pediococcus acidilactici (OHF3), Saccharomyces cerevisiae (OHF4)) were prepared. Samples were selected to OHF0, OHF2, OHF3 based on UPLC analysis, DPPH, ABTS radical scavenging activities. To evaluate the protective effect of OHF on liver injury mice, ICR mice were divided into 5 groups: Normal mice (Nor), LPS (20 mg/kg) treated mice (Veh), administrated OHF0, OHF2 OHF3 200 mg/kg body weight during 8 days before LPS injection. Serum and liver were collected 24 hours after LPS injection. Results : The activity was high in order of OHF0 and OHF3 in DPPH and ABTS radical scavenging activities. The quercetin contents for bioactive ingredient of OH was 5.39, kaempferol contents was 9.94 by UPLC analysis. The LPS-treated vehicle group significantly increased liver weight, and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in serum. In contrast, administrated OHF3 group decreased liver weight, AST, ALT. In addition, OHF3 groups reduced the elevated levels of reactive oxygen species (ROS) in serum and tissues. Moreover, AP-1, iNOS and COX-2 were significantly decreased in OHF2 and OHF3. But $NF-{\kappa}B$ p65 and $TNF-{\alpha}$ only showed a significant reduction in OHF3. Conclusions : Therefore, these results suggest that fermented Orostachydis Herba might be protective effect on liver injury through anti-oxidant effect.

Objectives: The aim of this study was to examine the effect of Asparagus cochinchinensis (AC) and fermented AC (fAC) on microorganisms and efficacies. Methods: AC was fermented for four weeks without using any bacterial strains. Then we investigated fermentation characteristics including potential of hydrogen (pH), total sugar, microbial profiling and antioxidant compound contents such as total polyphenol and total flavonoid. The anti-obesity effects of AC and fAC were evaluated by using Oil Red O staining in 3T3-L1 adipocyte. Also anti-diabetic effects of them were evaluated by using 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-d-glucose (2-NBDG) uptake in C2C12 skeletal muscle cell. Results: Both pH and total sugar of fAC were decreased significantly compared to unfermented AC. And the abundance of total bacteria and lactic acid bacteria increased during fermentation, especially Lactobacillus plantarum. Also fermentation of AC increased the content of total polyphenol. On the metabolic aspects, we found that AC and fAC suppressed fat accumulation. Conclusions: After four weeks of fermentation, AC increased concentrations of active compounds, altered microbial composition, and inhibited fat accumulation such as triglyceride. These results indicate that fermentation of AC might be a beneficial therapeutic approach for obesity.
Allergic skin inflammation such as atopic dermatitis (AD) is characterized by edema and infiltration with various inflammatory cells such as mast cells, basophils, eosinophils and T cells. Thymic stromal lymphopoietin (TSLP) is produced mainly by epidermal keratinocytes, as well as dermal fibroblasts and mast cells in the skin lesions of AD. Omega-3 polyunsaturated fatty acids in fish oil can reduce inflammation in allergic patients. Fermentation has a tremendous capacity to transform chemical structures. The antiinflammatory effects of fish oil have been described in many diseases, but the beneficial effects by which fermented olive flounder oil (FOF) modulates the allergic response is poorly understood. In this study, we produced FOF and tested its ability to suppress the various allergic inflammatory responses. The ability of FOF to modulate the immune system was investigated using a mouse model of AD. The FOF-treated group showed significantly decreased immunoglobulin E (IgE) and histamine in serum. Also, the increased TSLP expression was significantly inhibited in the FOF group; the FOF-treated group was not appreciably different from the hydrocort cream treatment group. In addition, FOF treatment resulted in a smaller spleen size with reduced the thickness and length compared to the induction group. Splenocytes from mice treated with FOF produced significantly less IFN-${\gamma}$, IL-4, T-box transcription factor (T-bet) and GATA binding protein 3 (GATA3) expression compared with the induction group. These results suggest that FOF may be effective in treating the allergic symptoms of AD. 5.
Objective : This study set out to combine the treatment efficacy of Taraxacum with Dongchimi fermentation and investigate Taraxacum's effects on protection of liver cell and controlling nitric oxide(NO) through experiments, thus checking whether it had values as a physiological active matter. The experimental materials include Taraxacum Dongchimi (TD) and Taraxacum fermented by Dongchimi (TDF). As for methodology, experiments were carried out to compare TD and TDF in components, protection effects for liver cells, anticancer effects on liver cells, and protection effects for brain cells in the aspects of liver function and immunity enhancement. Method : The experimental materials include Taraxacum Dongchimi (TD) and Taraxacum fermented by Dongchimi (TDF). As for methodology, experiments were carried out to compare TD and TDF in components, protection effects for liver cells, anti-cancer effects on liver cells, and protection effects for brain cells in the aspects of liver function and immunity enhancement. Results : As shown in the chromatogram results, each valid component content increased in Taraxacum fermented by Dongchimi (TDF) for each time section. Of them, the valid component content at 36.80 minutes was approximately 2.7 times higher in TDF at 21.8% than in Taraxacum Dongchimi (TD) at 8.28%. TDF generated more excellent protection effects against the toxicity that caused oxidative damage to the liver cell(HepG2) with t-BHP than TD. The survival rate was low in TD of $100{\mu}g/m{\ell}$ and $300{\mu}g/m{\ell}$ and increased to 23.3% in TDF of $100{\mu}g/m{\ell}$. The survival rate was the highest at $300{\mu}M$ with a significant difference of 68.1%(P<0.05). Both TD and TDF showed effects of controlling nitric oxide production according to concentration with TDF recording a higher rate of controlling nitric oxide production than TD. There were significant differences(P<0.05) in the effects of controlling nitric oxide production at 200 ug/ml, 400 ug/ml in both groups. Especially the result TDF of $400{\mu}g/m{\ell}$ was thus similar to those of butein, the positive control group. Conclusion : The result of this studies is that Taraxacum fermented by Dongchimi (TDF) increased the valid component content compared with the simple mixture(TD). The findings clearly show that it is a material with the effects of improving immunity and liver cell protection. If fermentation methods are further developed to use it as a functional material, it will be subject to more opportunities of being used in other functional foods and make a contribution to integrated medicinal food development.
Objectives : NK cells are spontaneously cytotoxic lymphocytes. These are not only important parts in the first line of defence against bacterial and viral infections of outside, but they may also play a critical role in chronic viral diseases. NK cells kill their targets spontaneously, without the need for prior sensitization and class I MHC restriction by the regulation of cytolytic functions and secretion of a variety of cytokines, such as interleukin-12(IL-12), MCP-1, IL-6, TNF-${\alpha}$, IFN-${\gamma}$. In addition, macrophage and NK cells cooperate through the production of cell mediates. These cooperation and modulation are one of major factors to prevent for evading immune surveillance of cancer. Hence, it could be assumed that if any candidate to enhance activities of macrophage and NK cell, it is considered as a potentially useful agents against cancer. Methods : In our study, to investigate effect of fermented soybean extracts by Lactic acid bacteria (SFE, soybean fermented extracts) work on intestinal immune cell to maintain general immune modulating and anti-cancer activity. We analyzed NK cytotoxicity assay and gene expressions of cytokine related with macrophage and NK cell activity. Results : In vitro experiment, SFE was verified as safety material for cell toxicicty to tumor cell strain without any toxicity of tumor growth inhibition and various cell strain. Effects of macrophage activity stimulating directly by SFE measured induced cytokine. The studies showed that IL-12 production by stimulation of SFE depended on concentration from 0.16mg/mL to 0.63mg/mL with non toxicity to cell, and it was the best activity at 0.63mg/mL. Besides, the effective concentration of SFE producing TNF-${\alpha}$ is similar to IL-12, but it was the best activity at 1.25mg/mL. The level of MCP-1, IL-6 and IFN-${\gamma}$ depended on concentration from 0.16mg/mL to 10mg/mL, IFN-${\gamma}$ showed the best activity at the effective concentration of 0.63mg/mL. With the result of NK cell activity measurement, the spleen cell of mouse injected SFE had 1.5 times higher killing effect than non injected cell. Conclusions : The result of this studies is that Soybean fermetated extracts(SFE) has possibility to immune aided material for the function not only inhibition of microbial infection to macrophage but also activity of adaption immune and cellular immune system.

Citrus, yield of which is the highest among fruits produced in Korea, is extensively consumed for processed food items. The amount of by-products of citrus produced from the processing within a short period after the harvest is tremendous. These by-products are mostly dumped into land or neglected because of cost involved in processing them. The aim of the present study was to explore the usefulness of the by-products as a new material by examining the anti-inflammatory activity of fermented extracts of citrus peels. The peels of 'unshu' (Citrus unshiu) was fermented with Aspergillus niger and their extracts before or after fermentation were analyzed using HPLC. The analysis showed that neohesperidin level considerably increased and the two new compounds were synthesized after fermentation. The anti-inflammatory activity of the fermented extracts was examined on RAW 264.7 murine macrophage cells stimulated with lipopolysaccharide. Fermented unshu extracts significantly enhanced the decrease of nitric oxide (NO) production, iNOS and COX-2 expression, comparing with those of unfermented extracts. Also TNF-${\alpha}$ and IL-6 production, both of which are pro-inflammatory cytokine, were more inhibited in fermented extracts. These results showed that the fermentation and promotion of the function of the by-products of citrus peels will help find a new application.

Although the effects of the rice bran have recently been investigated, there is no information regarding platelet physiology available. However, it is well known that fermented natural plants have a beneficial effect on cardiovascular diseases. Therefore, this study was conducted to investigate whether fermented rice bran extract (FRBE) with several plants (Artemisia princeps, Angelica Gigantis Radix, Cnidium officinale, and Camellia sinensis) affected agonist-induced platelet aggregation, and if so, what the underlying mechanism of its activity was. We performed several experiments, including in vitro platelet aggregation, intracellular calcium concentration and adenosine triphosphate release. In addition, the activation of integrin ${\alpha}_{II}b{\beta}3$ was determined using fibrinogen binding. Thrombus formation was also evaluated in vivo using an arterio-venous shunt model. The FRBE inhibited collagen-induced platelet aggregation in a concentration-dependent manner. FRBE significantly and dose dependently attenuated thrombus formation using rat arterio-venous shunt. FRBE suppressed the intracellular calcium mobilization in collagen-stimulated platelets. We also found that FRBE inhibited extracellular stimuli-responsive kinase 1/2, p38-mitogen-activated protein kinases and c-Jun N-terminal kinase phosphorylation. These results suggested that FRBE inhibited collagen-induced platelet aggregation, which was mediated by modulation of downstream signaling molecules. In conclusion, FRBE could be developed as a functional food against aberrant platelet activation-related cardiovascular diseases.
Objectives: To investigate the effect of fermented extract of Artemisiae Iwayomogii Herba, Curcumae Longae, Crataegi Fructus and Salviae Miltiorrhizae Radix (FMH) on anti-inflammation associated with dyslipidemia and anti-oxidation in RAW264.7 and HUVEC cells. Methods: The total polyphenols, total flavonoids, DPPH radical scavenging activity, ABTS radical scavenging activity, and cytotoxicity of FMH were measured. RAW264.7 cells treated with FMH were tested for production of NO, and for cytokine and LTB4 levels and HUVEC cells treated with FMH were examined for production of cDNA of genes related to inflammation. Results: 1. FMH contained polyphenols and flavonoids. The DPPH and ABTS radical scavenging activity of FMH increased in a concentration-dependent manner. 2. FMH treatment inhibited the production of nitric oxide (NO), cytokines, and LTB4 in RAW264.7 cell when compared to the untreated control group. 3. FMH decreased the transcription of pro-inflammatory genes, whereas it increased transcription of anti-inflammatory genes, in HUVEC cells. Conclusion: FMH is effective as an antioxidant and for treatment and prevention of dyslipidemia, atherosclerosis, ischemic heart disease, stroke, and other cardiocerebrovascular diseases.
Extracts of soybeans fermented by Bacillus subtilis have a wide variety of functions, such as enhancing the body's immune function, fibrinolysis activity, anti-inflammation, anti-cancer, estrogen function and anti-infection effects. Recently, it was reported that the extracts of fermented beans exhibit strong anti-inflammatory and anti-cancer properties by suppressing the transcription of pro-inflammatory cytokine genes and induction of apoptosis, respectively. However, the mechanisms of their cytotoxicity in human gastric cancer cells are poorly understood. In the present study, we investigated the effects of ethyl alcohol extracts from fermented soybean (FS) and yellow agabean (FYA) on cell growth and apoptosis in AGS human gastric cancer cells. A treatment of FS and FYA inhibited the growth of AGS cells in a concentration-dependent manner by inducing apoptosis. FS- and FYA-induced apoptosis were associated with down-regulation of XIAP and cIAP-2, and up-regulation of pro-apoptotic Bax expression. Moreover, a treatment of FS and FYA not only triggered an increase in the levels of death receptor (DR)4, DR5, Fas and FasL, but also induced the activation of casepase-3, -8 and -9. These findings illustrate that FS and FYA may have a therapeutic potential in human gastric AGS cells and as a functional food.
