This study was to evaluate the effect of Samjayangchin-tang (STYCT) on mouse Th1 and Th2 cells' differentiation and ovalbumin (OVA)-induced allergic inflammation. The proliferation of mouse CD4 T cells and the secretion of Th1/Th2 cytokines under the influence of STYCT extract were measured as well as the amount of ${\beta}-hexosaminidase$ in RBL-2H3 cells and the levels of $TNF-{\alpha}$ and IL-6 secretion in Raw264.7 cells. BALB/c mice were orally administered with STYCT extract and simultaneously inoculated with OVA to induce allergic reaction and measure the level of total IgE, OVA-specific IgE and the production of IFN- g, IL-4, IL-5 by the spleen cells. When mouse CD4 T cell were stimulated with anti-CO3 and anti-CD28 for 48 hours in various concentrations of STYCT extract, it decreased proliferation of CD4 cells. CD4 T cells under Th1/Th2 polarizing conditions for 3 days with STYCT resulted in mild decrease of IFN- g in Th1 cells and significant decrease of IL-4 in Th2 cells. STYCT extract had a dose-dependent inhibitory effect on antigen-induced release of ${\beta}-hexosaminidase$ in RBL-2H3 cells. Treatment of STYCT extract on LPS stimulated Raw 264.7 cells showed dose-dependent decrease in IL-6 production. Oral administration of STYCT extract on OVA-induced allergic mice showed an inhibitory effect on the levels of total serum IgE and OVA-specific IgE by 53% and 44%, respectively. Culture of spleen cells with OVA resulted in significant increase of IFN- g by 54% and significant decrease of IL-4 and IL-5 by 42%, and 29%, respectively. The results show that STYCT does not strongly induce mouse T cells to transform into Th1 or Th2 but it has an anti-allergic effect in vitro, and that it also corrects the unbalance between the reactions of Th cells in allergic diseases.

The purpose of this study was to investigate the anti-obesity and anti-inflammation effect of the cheonggukjang (a soybean paste fermented for only a few days) in diet induced obesity mice. Weight gain was significantly decreased in the mice fed cheonggukjang compared High Fat Diets (HFD). The HFD plus cheonggukjang (CGJ) were also effective in improving the lipid metabolism. The levels of plasma triglyceride, cholesterol, ALT, AST, leptin, glucose, and insulin were significantly lower in CGJ than HFD group (p<0.05). The adiponectin level of CGJ group was significantly increased compared to the HFD group (p<0.05). In the CGJ group, the mRNA expression of adipogenic genes in the liver and adipose tissues, which are transcription factors crucial for adipogenesis, were significantly suppressed (p<0.05). The number of $CD11b^+F4/80^+$ T cells, $Gr-1^{int}CD11b^{high}$ cells, and $Gr-1^{int}CD11b^{high}$ cells were significantly higher in HFD group than CGJ group (p<0.05). The size of adipocyte was significantly reduced in CGJ group compared to HFD group. In addition, the contents of liver lipid droplets were significantly downregulated in the CGJ mice than HFD mice (p<0.05). Collectively, these data suggest the novel function of cheonggukjang in modulating adipogenesis through an immune function-alteration involving downregulation of adipogenic transcription factors and macrophage activation.

In this study, we investigated the anti-inflammatory effects of fermented Hizikia fusiformis extracts in lipopolysaccharide (LPS)-stimulated RAW 264.7 mouse macrophages. The fermentation was performed using Lactobacillus casei in mixture of carbon source at $30^{\circ}C$ for 30 days. The sample groups were prepared with/without L. casei group in order to demonstrate the anti-inflammatory activity of fermented H. fusiformis in regard to lactic acid bacteria. As a result, we confirmed the inhibitory effect of H. fusiformis extracts on LPS-stimulated NO production and expression of $TNF{\alpha}$, while it had no regulatory effect on the expression of iNOS, COX-2, $IL-1{\beta}$ and IL-6 as important inflammatory factors. However, L. casei fermented group significantly suppressed the expression of the above factors. In particular, the difference between the two groups in the matter of mRNA expression of iNOS, which is directly associated with NO production, indicated that the fermentation with lactic acid bacteria effectively suppressed NO production by regulating iNOS expression. Also, effective suppression of pro-inflammatory cytokines showed that the fermentation using L. casei may provide an increment towards extraction of active ingredients that are effective anti-inflammatory agents.

Kojongsi persimmon (Diospyros kaki L.) is the major cultivar of dried persimmon in Korea. The purpose of this study was to investigate the antioxidant and anti-inflammatory activities of water-soluble extracts from the calyx (PCE), peel (PPE) and leaf (PLE) of Kojongsi persimmon. PCE showed the highest total phenolic and flavonoid contents. In addition, the antioxidant activities (diphenylpicrylhydrazyl, 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid), nitric oxide and reducing power) of PCE were higher than those of PPE and PLE. Moreover, PCE, PPE and PLE significantly suppressed the production of inflammatory mediators (nitric oxide and $prostaglandinE_2$) and pro-inflammatory cytokines (tumor necrosis factor-${\alpha}$ and interluekin-$1{\beta}$) by lipopolysaccharide-stimulated RAW 264.7 cells in a dose-dependent manner. PCE showed the highest anti-inflammatory activity. Thus, these results suggest that the calyx of Kojongsi persimmon may be highly valuable as a natural product owing to its high-quality functional components as well as its-antioxidant, ant-iinflammatory activities.

To investigate the industrial availability of liquid fermentation (PL-ferment) by Phellinus linteus mycelium as a postbiotics for the inhibition of inflammation, PL-ferment was fractionated into culture supernatant (CS), hot-water extract (HW) from PL-ferment, EtOH-precipitate (CP) fractionated from HW, and the dialysate (DCP) of CP. Compared to the other fractions, DCP which is expected to contain exopolysaccharide (EPS) as the major component, significantly decreased the production of NO, IL-6, and MCP-1 in LPS-induced RAW 264.7 cells, and IL-6 and IL-8 in TNF-α and IFN-γ-induced HaCaT cells. The general component analysis results showed that no significant difference in components was observed between the fractions, whereas sugar composition analysis revealed that DCP had decreased glucose and increased mannose contents compared to the other fractions. This suggests that mannose played an important role in the anti-inflammatory activity of the active fraction, DCP. Molecular weight distribution analysis revealed that DCP was mainly composed of low-molecular-weight material-removed high-molecular-weight polysaccharides of 18-638 kDa, suggesting that EPS originated from P. linteus EPS. In conclusion, our results suggest that the DCP of P. linteus mycelium fermentation using the anti-inflammatory activity could be used industrially as postbiotic material.

Schisandra chinensis (SC) and Lycium chinense (LC) were widely distributed in Asia and the fruit has been used traditionally for medicinal herbs. The processing method was solid-state fermentation using Aspergillus oryzae for 48 h after stir-frying treatment at $220^{\circ}C$ for 12 min. In this study, in vitro the anti-inflammatory effect and in vivo hangover reduction were compared to unprocessed SC and LC water extract. Anti-inflammatory effects have been evaluated in pro-inflammatory mediators which were secreted by lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Nitric oxide (NO) was determined using Griess reaction. Proinflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin $(IL)-1{\beta}$ were measured by enzyme-linked immunosorbent assays (ELISA). Alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities were compared to processed SC or LC and mixtures thereof (1:1). In vivo study was compared to hangover relief in alcohol-fed mice. After administering a mixture of SC and LC (300 mg/kg) water extract (1:1), mice were fed 3 g/kg of ethanol. Serum was collected at 1, 3, and 5 h intervals to analyze ethanol and acetaldehyde levels using a colorimetric assay kit. The processed SC and LC water extracts compared to raw materials significantly inhibited LPS-induced NO and inflammatory cytokine production in RAW 264.7 cells. The results of the hangover mouse model are also consistent with anti-inflammatory effects. These results suggest that processed SC and LC extracts may be functional materials for the treatment of inflammation and hangover.

Deterioration of the immune function weakens the body's resistance to various infections, leading to a series of diseases. Immunomodulatory biomaterials have been used to reduce the side effects of immunosuppressants or to enhance immunity. Agarwood is the aromatic resinous portion of Aquilaria trees that has been traditionally used as a medicinal herb for the treatment of various diseases. Although previous studies have shown that agarwood can improve the body's immunity, evidence for this claim is still lacking. In this study, the immune-enhancing effects of the agarwood methanol extracts of Aquilaria malaccensis Lamk were evaluated in a RAW 264.7 macrophage model. Based on the results, the agarwood extracts markedly enhanced phagocytosis in the absence of cytotoxicity. The agarwood extract-treated RAW 264.7 cells exhibited the typical morphology of activated macrophages, which are spindle-shaped with elongated filopodia. Agarwood extract also significantly increased the production of nitric oxide (NO), which is associated with the increased expression of inducible NO synthase. Moreover, the secretion and expression levels of cytokines, such as tumor necrosis factor-α and interleukin (IL)-1β and IL-6, were increased by agarwood treatment. Notably, these are also associated with a mitogen-activated protein kinase signaling pathway. Taken together, our findings provide scientific evidence that agarwood has potential immune-enhancing effects in vitro.

The present study aimed to develop new physiologically active ingredients from Angelica gigas. The polysaccharides purified from A. gigas, AGE-2c-I, showed potent anti-complementary activity in a dose-dependent manner. C₃ activation products were identified through crossed immuno-electrophoresis using anti-human C₃ antibodies and the anti-complementary activity of AGE-2c-I under Ca⁺⁺-free conditions suggests that AGE-2c-I may induce complementary activation via both alternative and classical pathways. In addition, AGE-2c-I augmented the production of various cytokines, such as interleukin (IL)-6, IL-10, IL-12, and tumor necrosis factor-α, by peritoneal macrophages. Furthermore, intravenous (i.v.) administration of AGE-2c-I dose-dependently enhanced natural killer cell cytotoxicity against YAC-1 lymphoma. In experimental lung metastasis, prophylactic i.v. administration of AGE-2c-I inhibited lung metastasis by 58% at 100 ㎍/mouse. From the above results, we suggest that AGE-2c-I purified from A. gigas has potent immune system-stimulating activities, and is a potentially promising food ingredient beneficial to human health.

Objective: To examine the effects of Trichosanthes kirilowii Maximowicz extract (TE) and Trichosanthes kirilowii Maxi mowicz Cheonghyeol Plus Phellinus linteus Cheonghyeol plus (TCP) on anti-inflammatory factor expression in human umbilical vein endothelial cells (HUVECs). Methods: HUVECs were activated with TNF-α and then treated with TE and TCP. The expression levels were then measured for intracellular genes (KLF2, eNOS, MCP-1, ICAM-1, and VCAM-1), proteins (KLF2, eNOS, MCP-1, ICAM-1, VCAM-1, ERK, and JNK, p38), and extracellular biomarkers (ICAM-1, VCAM-1, and MCP-1). Results: 1. TCP at concentrations of 100 ㎍/mL or greater significantly increased the expression of KLF2 and eNOS intracellular genes and significantly decreased the expression of ICAM-1, VCAM-1, and MCP-1 genes compared to the control group. 2. TCP at concentrations of 100 ㎍/mL or greater significantly increased the expression of KLF2, eNOS proteins compared to the control group, and significantly reduced the expression of VCAM-1, ICAM-1, MCP-1, ERK, and p38 proteins. However, JNK protein phosphorylation showed no significant change compared to the control group. 3. TCP at concentrations of 100 ㎍/mL or more significantly decreased the production of MCP-1, ICAM-1, and VCAM-1 extracellular biomarkers compared to the control group. 4. TE at a concentration of 100 ㎍/mL did not cause any significant change in the expression of intracellular genes or proteins, in the production of the extracellular biomarker MCP-1, or in the amount of JNK protein compared to the control group. Other intracellular genes, proteins, and extracellular biomarker expression showed the same trend as observed with TCP exposure. Conclusion: This study experimentally confirmed that TE and TCP could be effective in preventing or inhibiting various inflammatory vascular diseases due to their anti-inflammatory effects.
