The purpose of this study was to investigate the possibility of enhancing the functional compounds in apple and pear pomace (APP) by fermentation with mycelia from the mushroom Lentinula edodes. A 30% (w/v) APP with added rice bran and Biji was fermented with L. edodes at $24^{\circ}C$ and 80% humidity. The cellulase and pectinase activities in the fermented APP (FAPP) were higher than those in the non-fermented control. In addition, the physiological activities of the FAPP, including DPPH, ABTS radical scavenging, and SOD-like activity, as well as the total polyphenol and ${\beta}-glucan$ contents were higher than those in the control. FAPP treatment significantly reduced LPS-induced nitric oxide (NO) levels in Raw 264.7 cell. Therefore, FAPP treatment was considered to more effectively suppress cell injury caused by inflammatory cytokines through inhibition of LPS-induced NO production. These results suggest that the levels of functional components in APP can be increased by fermentation with this mushroom mycelium. However, further studies are needed before it can be used as a functional material.

While searching for useful microorganisms, Saccharomycopsis fibuligera which can be used as cosmetic materials were divided from Jeju island's traditional fermented foods. In this study, blackcurrant extract which contains a large amount of anthocyanin glycosides was fermented with S. fibuligera. HPLC analysis was performed to analyze the components of blackcurrant extract (BE) and fermented blackcurrant fruit extract (FBE). As a result, bio-conversion of delphinidin and cyanidin were able to be identified. In order to verify the anti-oxidant effect of BE and FBE, we investigated radical scavenging ability with DPPH and ABTS. In addition, to confirm anti-inflammatory effect, we investigated inhibition effect of nitric oxide (NO) production on lipopolysaccharide (LPS) - stimulated RAW264.7 macrophages, and inhibition effect of the expression of inflammatory-related proteins (iNOS, COX-2) by western blot analysis. As a result, as FBE has anti-oxidant and anti-inflammatory effects, we suggest that it might be used as an active ingredient for cosmetics.

In this study, Cyperus rotundus (C. rotundus) was fractionated into ethyl acetate to identify α-cyperone, a representative indicator, and its ethyl acetate fraction were evaluated to confirm the possibilityas a functional cosmetic ingredient. As a result of HPLC analysis, it was confirmed that the content of α-cyperone was 5.243%. In order to verify the inflammatory relief effect of the ethyl acetate fraction from C. rotundus (EAFC) and α-cyperone, it was confirmed that nitric oxide (NO) production inhibitory ability in RAW 264.7 macrophages induced an inflammatory reaction with lipopolysaccharide (LPS). Real-time qPCR analysis confirmed inhibition of mRNA expression level of inflammatory factors, IL-1β, IL-6, TNF-α, COX-2 and iNOS. As a results of conducting a clinical study using a simple cosmetic formulation containing EAFC, it was confirmed that the skin irritation stimulated by sodium lauryl sulfate (SLS) was calming and relieving itching. Through these results, it is believed that the C. rotundus can be used as a natural cosmetic ingredient that has the effect of inhibiting inflammation and relieving itching.

Objectives : The purpose of this study was to investigate effects of Houttuyniae Herba water extract (HC) on calcium release and production of various inflammatory mediators such as nitric oxide (NO), interferon-inducible protein (IP)-10, platelet derived growth factor (PDGF)-BB, keratinocyte-derived chemokine (KC), vascular endothelial growth factor (VEGF), interleukin (IL)-4, and IL-5 in lipopolysaccharide (LPS)-induced RAW 264.7 mouse macrophages. Methods : NO production was measured by Griess reagent assay. Intracellular calcium level was measured with Fluo-4 assay. Levels of cytokines were measured by High-throughput multiplex bead array cytokine assay based on xMAP (multi-analyte profiling beads) technology. Results : HC significantly decreased NO production for 24 hrs incubation at the concentrations of 10, 25, 50, 100, and $200{\mu}/mL$ in LPS-induced RAW 264.7 (P < 0.05). HC significantly decreased production of IP-10, KC, VEGF, and PDGF-BB for 24 hrs incubation at the concentrations of 50, 100, and $200{\mu}/mL$ in LPS-induced RAW 264.7 (P < 0.05). HC also significantly decreased intracellular calcium release for 24 hrs incubation at the concentrations of 25, 50, 100, and $200{\mu}/mL$ in LPS-induced RAW 264.7 (P < 0.05). But HC did not show any significant effect on production of IL-4 and IL-5 in LPS-induced RAW 264.7. Conclusions : The results suggested that HC has anti-inflammatory property related with its inhibition on the production of NO, IP-10, KC, VEGF, and PDGF-BB in LPS-induced macrophages via calcium pathway.

Objectives : Hwanggeumjakyak-tang (huangqin shaoyao tang, HJT) has been used to treat acute enteritis in traditional oriental medicine. However, there has been a lack of studies regarding the effects of HJT on the inflammatory activities and effector inflammatory disease mechanism about macrophage before is not known. So we examined the effect of HJT water extract on pro-inflammatory mediators in lipopolysaccharide (LPS) - stimulated mouse macrophage, RAW 264.7 cells. Methods : Cells were treated with 2 ug/mL of LPS 1 h prior to the addition of HJT. Cell viability was measured by MTS assay. The production of nitric oxide (NO) was determined by reacting cultured medium with Griess reagent. The expression of cyclooxygenase-2 (COX-2), inducible NO synthase (iNOS) and mitogen-activated protein kinases (MAPKs) was investigated by Western blot, RT-PCR. The content of level of cytokines (prostaglandin (PG) $E_2$, interleukin (IL)-6, IL-12, Tumor necrosis factor-alpha (TNF-${\alpha}$) and monocyte chemoattractant protein-1 (MCP-1)) in media from LPS-stimulated Raw 264.7 cells was analyed by ELISA kit. Results : HJT inhibited the production of NO, $PGE_2$, IL-6 as well as the expressions of iNOS, COX-2 but did not inhibit the production of IL-12, TNF-${\alpha}$, MCP-1 in the murine macrophage, RAW 264.7 cells. HJT also had suppression effects of LPS-induced MAPKs activation Conclusion : These results suggest that HJT has an anti-inflammatory therapeutic potential, which may result from inhibition of MAPK phosphorylation, thereby decreasing the expression of pro-inflammatory genes.
Objectives : This study aimed to investigate the unknown mechanisms behind the anti- inflammatory activity of Hyeonto-dan(HT) 70% ethanol extract on LPS-stimulated RAW 264.7 cells. Methods : Cells were treated with Hyeonto-dan 1 h prior to addition of 200 ng/mL of LPS. Cell viability was measured by the MTS assay. Nitric oxide levels were determined by the Griess assay. $PGE_2$ were measured using EIA kit. Pro-inflammatory cytokine production was measured by the enzyme-linked immunosorbent assay (ELISA). The expression of COX-2, iNOS, and MAPKs was investigated by Western blot, qRT-PCR. $NF-{\kappa}B$/p65 localization and interaction of the TLR-4 receptor with LPS was examined by immunofluorescence assays. Results : Hyeonto-dan had no cytotoxicity at the measured concentration. Hyeonto-dan inhibited NO production and pro-inflammatory cytokines such as IL-6, $TNF-{\alpha}$, and PGE2 as well as the protein and mRNA expression of iNOS and COX-2. Moreover, Hyeonto-dan inhibited the interaction between LPS and TLR-4 in murine macrophages. It suppressed phosphorylation of extracellular signal-regulated kinase (ERK 1/2), c-jun N-terminal kinase (JNK 1/2) and p38. Finally, it inhibited translocation of $NF-{\kappa}B$ in response to competitive LPS. Conclusions : Based on the results of this study, Hyeonto-dan inhibited the binding of TLR-4 receptor to LPS and inhibited the phosphorylation of extracellular signaling pathway MAPKs. These inhibitory effects are thought that the amount of $NF-{\kappa}B$ delivered to the nucleus was decreased and the inflammatory reaction was prevented by decreasing the production of LPS-induced $PGE_2$, NO, IL-6 and $TNF-{\alpha}$.

In this study, exosomes were isolated by ultrafiltration from Lactobacillus rhamnosus J2K-821 and their various effects for skin were evaluated. Their size and concentration were identified 50 ~ 200 nm and 3.22 × 108 particles/mL, respectively through nanoparticle tracking analysis. In order to verify the inflammatory relief effect of Lactobacillus rhamnosus-derived exosomes (LRDEs), their nitric oxide (NO) production inhibitory ability in RAW 264.7 macrophages induced an inflammatory reaction with lipopolysaccharide (LPS) was confirmed. It was revealed that they inhibited NO production in a concentration-dependent manner. To evaluate the antioxidant activity and skin barrier improvement effect of LRDEs, their 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and hyaluronidase inhibitory activity were confirmed. It was also revealed that their activities were increased by concentration-dependent manner. Through these results, It is believed that LRDEs can be used as a effective natural cosmetic ingredient for anti-inflammation, antioxidation and skin barrier improvement.

This study is to propose Lagerstroemia indica flower as an anti-acne cosmetic material, and confirmed the sebum control, anti-inflammatory, and antioxidant effects using Lagerstroemia indica flower extract (LIFE) . As a result of evaluating the sebum control effectiveness, it was confirmed that LIFE inhibited the production of sebum excessively induced with palmitic acid up to 65%. Subsequently, it was confirmed that LIFE has an antibacterial effect and the ability to inhibit lipase activity against Cutibacterium acnes (C. acnes), which mainly appears in acne lesions, and can also reduce the inflammatory response caused by virulence factors secreted by C. acnes. It was also confirmed that LIFE inhibited the secretion of nitrogen monoxide (NO) and prostaglandin E2 (PGE2), which are inflammatory mediators induced by LPS in macrophages, by 75% and 54%, respectively, and that it also had a high DPPH radical scavenging ability similar to that of ascorbic acid. These results suggest that LIFE, a natural extract, can be used as an anti-acne material to relieve and treat acne, a complex disease, by controlling sebum production and having antibacterial and lipase activity inhibiting against C. acnes, and anti-inflammatory, antioxidant properties.

Background: Sarcoidosis is a chronic granulomatous inflammatory disease of unknown etiology often involving the lungs and intrathoracic lymph nodes. The natural course of sarcoidosis is variable from spontaneous remission to significant morbidity or death. But, the mechanisms causing the variable clinical outcomes or any single parameter to predict the prognosis was not known. In sarcoidosis, the number and the activity of CD4 + lymphocytes are significantly increased at the loci of disease and their oligoclonality suggests that the CD4 + lymphocytes hyperreactivity may be caused by persistent antigenic stimulus. Recently, it has been known that CD4+ lymphocytes can be subdivided into 2 distinct population(Th1 and Th2) defined by the spectrum of cytokines produced by these cells. Th1 cells promote cellular immunity associated with delayed type hypersensitivity reactions by generating IL-2 and IFN-$\gamma$. Th2 cells playa role in allergic responses and immediate hypersensitivity reactions by secreting IL-4, IL-5, and IL-10. CD4+ lymphocytes in pulmonary sarcoidosis were reported to be mainly Th1 cells. IL-12 has been known to play an important role in differentiation of undifferentiated naive T cells to Th1 cells. And, Moller et al. observed increased IL-12 in bronchoalveolar lavage fluid(BALF) in patients with sarcoidosis. So it is possible that the elevated level of IL-12 is necessary for the continuous progression of the disease in active sarcoidosis. This study was performed to test the assumption that IL-12 can be a marker of active pulmonary sarcoidosis. Methods: We measured the concentration of IL-12 in BALF and in conditioned medium of alveolar macrophage(AM) using ELISA(enzyme-linked immunosorbent assay) method in 26 patients with pulmonary sarcoidosis(10 males, 16 females, mean age: $39.8{\pm}2.1$ years) and 11 normal control. Clinically, 14 patients had active sarcoidosis and 12 patients had inactive. Results: Total cells counts, percentage and number of lymhocytes, number of AM and CD4/CD8 lymphocyte ratio in BALF were significantly higher in patients with sarcoidosis than in control group. But none of these parameters could differentiate active sarcoidosis from inactive disease. The concentration of IL-12 in BALF was significantly increased in sarcoidosis patients ($49.3{\pm}9.2$ pg/ml) than in normal control ($2.5{\pm}0.4$ pg/ml) (p<0.001). Moreover it was significantly higher in patients with active sarcoidosis ($70.3{\pm}14.8$ pg/ml) than in inactive disease ($24.8{\pm}3.l$ pg/ml) (p=0.001). Also, the concentration of IL-12 in BALF showed significant correlation with the percentage of AM(p<0.001), percentage(p<0.001) and number of lymphocyte(p<0.001) in BALF, suggesting the close relationship between the level of IL-12 in BALF and the inflammatory cell infiltration in the lungs. Furthermore, we found a significant correlation between the level of IL-12 and the concentration of soluble ICAM-1 : in serum(p<0.001) and BALF (p=0.001), and also between IL-12 level and ICAM-1 expression of AM(p<0.001). The AM from patients with pulmonary sarcoidosis secreted significantly larger amount of IL-12 ($206.2{\pm}61.9$ pg/ml) than those of control ($68.3{\pm}43.7$ pg/ml) (p<0.008), but, there was no difference between inactive and active disease group. Conclusion : Our data suggest that the BALF IL-12 level can be used as a marker of the activity of pulmonary sarcoidosis.

Background : Matrix metalioproteinase(MMP)-2 and MMP-9 have been known to play an important role in cell migration and the tissue remodeling process by type IV collagen lysis, a major component of the basement membrane. Intra-alveolar fibrosis, secondary to an injury to the basement membrane of the alveolar epithelial lining, is a major process in the pathogenesis of idiopathic pulmonary fibrosis(IPF). Therefore, MMP-2 and MMP-9 was hypothesized to play an important role in IPF pathogenesis. As a result, their level may reflect the activity or prognosis. Method : Forty one progressive IPF patients(age $59.82{\pm}1.73$ years, M:F=23:18), 16 patients with stable IPF for more than one year without therapy(age : $63.6{\pm}2.8$ years, M:F=13:3), and 7 normal controls were enrolled in this study. The MMP-2 and MMP-9 levels in the BAL fluid and alveolar macrophage conditioned media(AM-CM) were measured by zymography and the TIMP-1 level was measured by ELISA. Results : 1) The MMP-2 level in BALF was highest in the progressive IPF group ($1.36{\pm}0.28$) followed by the stable group ($0.46{\pm}0.13$) and the controls ($0.08{\pm}0.09$), which was statistically significant. The MMP-9 level of the IPF ($0.31{\pm}0.058$) and the stable group ($0.22{\pm}0.078$) were higher than that of the control group ($0.002{\pm}0.004$). In the AM-CM, only MMP-9 was detected, which was significantly higher in IPF group ($0.80{\pm}0.1O$) than in the control group($0.23{\pm}0.081$). The TIMP-1 level was also higher in both the IPF ($36.34{\pm}8.62\;{\mu}g/ml$) and stable group ($20.83{\pm}8.53\;{\mu}g/ml$) compared to the control group ($2.80{\pm}1.05\;{\mu}g/ml$) (p<0.05). 3) There was a correlation between the MMP-2 level in the BALF with the total cell number(r=0.298) and neutrophils(r=0.357) (p<0.05), and the MMP-9 level with the number of neutrophils (r=0.407) and lymphocytes (r=0.574)(p<0.05). The TIMP-1 level correlated with the total number of cell (r=0.338, p<0.05) and neutrophils(r=0.449, p=0.059). Conclusion : Both MMP and TIMP appear to play an important role in IPF pathogenesis, and their level may reflect the disease activity.
