Objectives: The purpose of this study was to investigate the in vitro anti-inflammatory, anti-pruritic and antimicrobial effects of the three herbal prescription (EST, SCT, WDT), which has been traditionally used for treating leukorrhea induced by various infections in the female genital tract. Methods: In this experiment, the anti-inflammatory effects were evaluated by Nitric oxide (NO), $Interlukine-1{\beta}$ ($IL-1{\beta}$), Interlukine-2 (IL-2), Interlukine-6 (IL-6), Tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), Prostaglandin $E_2$ ($PGE_2$), Leukotriene $B_4$ ($LTB_4$) production amount and Inducible nitric oxide synthase (iNOS), Nuclear factor kappa B ($NF-{\kappa}B$), Cyclooxygenase-2 (COX-2) gene expression levels in RAW264.7 cells. And the anti-pruritic effects were evaluated by Histamine, Acetylcholine (ACh), Acetylcholinesterase (AChE), Substance P production amount in Mast cell/9 (MC/9) and Pheochromocytoma 12 (PC12) cells. The anti-microbial effect was measured by inhibition zone diameter on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger. Results: As a result of measuring anti-inflammatory efficacy, $IL-1{\beta}$, IL-2, IL-6, $TNF-{\alpha}$, $PGE_2$, and $LTB_4$ production amounts were significantly reduced in the EST, SCT, WDT extraction groups compared with the control group, and significantly decreased the amount of $NF-{\kappa}B$, iNOS, and COX-2 gene expression and the amount of Phospho-Inhibitor kappa B alpha ($p-I{\kappa}B-{\alpha}$)/Inhibitor kappa B alpha ($I{\kappa}B-{\alpha}$) and $NF-{\kappa}B$ p65 protein expression. In addition, As a result of measuring the anti-pruritic effect, the amounts of histamine, ACh and Substance P were significantly decreased, and AChE production was slightly decreased, but it's significance did not appear. Finally the anti-microbial effects of EST, SCT, WDT extraction groups against Pseudomonas aeruginosa, Candida albicans and Aspergillus niger was inhibited, however the growth of Escherichia coli and Staphylococcus aureus was not inhibited. Conclusions: These data suggest that EST, SCT, WDT can be used to treat patients with leukorrhea.

The aim of this study was to investigate the effects of red ginseng-derived non-saponin fraction (NSF) on inflammatory responses and monocyte-to-macrophage differentiation in RAW264.7 and THP-1. NSF effectively inhibited inflammatory responses by downregulating nitric oxide (NO) production and protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). NSF ($2000{\mu}g/mL$) decreased the levels of NO, iNOS, and COX-2 by 33, 83, and 64%, respectively. NSF inhibited the differentiation of monocyte-to-macrophage by decreasing cell adherence along with downregulation of the cluster of differentiation molecule $11{\beta}$ ($CD11{\beta}$) and CD36. In addition, pro-inflammatory cytokines, such as tumor necrosis factor-alpha, interleukin 6, and monocyte chemoattractant protein 1 (MCP-1), were significantly reduced with NSF treatment. The NSF-mediated inhibition of inflammatory responses was due to the regulation of nuclear factor kappa-light-chain-enhancer of activated B cells ($NF-{\kappa}B$) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2). NSF effectively suppressed the translocation of $NF-{\kappa}B$ into the nucleus, while nuclear Nrf2 and its target protein, heme oxygenase-1, levels were significantly increased.

Background: Nonalcoholic steatohepatitis (NASH) is one of the chronic inflammatory liver diseases and a leading cause of advanced liver fibrosis, cirrhosis, and hepatocellular carcinoma. The main purpose of this study was to clarify the effects of GBCK25 fermented by Saccharomyces servazzii GB-07 and pectinase, on NASH severity in mice. Methods: Six-wk-old male mice were fed either a normal diet (ND) or a Western diet (WD) for 12 wks to induce NASH. Each group was orally administered with vehicle or GBCK25 once daily at a dose of 10 mg/kg, 20 mg/kg, 100 mg/kg, 200 mg/kg, or 400 mg/kg during that time. The effects of GBCK25 on cellular damage and inflammation were determined by in vitro experiments. Results: Histopathologic analysis and hepatic/serum biochemical levels revealed that WD-fed mice showed severe steatosis and liver injury compared to ND-fed mice. Such lesions were significantly decreased in the livers of WD-fed mice with GBCK25 administration. Consistently, mRNA expression levels of NASH-related inflammatory-, fibrogenic-, and lipid metabolism-related genes were decreased in the livers of WD-fed mice administered with GBCK25 compared to WD-fed mice. Western blot analysis revealed decreased protein levels of cytochrome P450 2E1 (CYP2E1) with concomitantly reduced activation of c-Jun N-terminal kinase (JNK) in the livers of WD-fed mice administered with GBCK25. Also, decreased cellular damage and inflammation were observed in alpha mouse liver 12 (AML12) cells and RAW264.7 cells, respectively. Conclusion: Administration of GBCK25 ameliorates NASH severity through the modulation of CYP2E1 and its associated JNK-mediated cellular damage. GBCK25 could be a potentially effective prophylactic strategy to prevent metabolic diseases including NASH.

In this study, we analyze the antioxidant and anti-inflammatory activities of various extracts of Cryptoporus volvatus. Three extracts were prepared using hot-water, 70% ethanol, and 70% methanol. Compared to the hot-water and 70% methanol extracts, the 70% C. volvatus ethanol extracts showed significantly higher DPPH radical scavenging activities (76.1%), nitrite scavenging activities (29.5%), and total polyphenol content (9.17 mg GAE/g). The DPPH radical and nitrite scavenging activities of C. volvatus both correlated significantly with the total polyphenol content. The Pearson's correlation coefficient of DPPH radical and nitrite scavenging activities with total polyphenol content were r = 0.744 (p<0.05) and r = 0.921 (p<0.01), respectively. To test their anti-inflammatory effects, nitric oxide production and cell viability were measured by performing nitric oxide (NO) and MTT assays on lipopolysaccharide-treated RAW 264.7 cells. The NO production levels of the 70% ethanol extract-treated cells were slightly lower than those of the others. In our MTT assay, the hot-water extracts showed higher cell viabilities (81.4%) than those of 70% ethanol and 70% methanol extracts. The ${\beta}$-glucan content of C. volvatus was 37.8%. From the results of this study, it is suggested that C. volvatus, an easily accessible wild mushroom, has potential to be used in the development of medicines, cosmetics, and functional health foods.

Centella asiatica (CA) has been widely used as herbal plants. It is a valuable resources. The aim of the present study was to evaluate physiological activities of solvent extracts from CA cultivated in Chungju, Korea (Good tiger care). After preparing water (cold-water, CA-WE; hot-water, CA-HWE) and EtOH extracts (50% EtOH, CA-50E; 70% EtOH, CA-70E), their total polyphenol, flavonoid, and triterpenoid contents, and anti-oxidant activities, and anti-inflammatory activities were examined and compared. CA-70E showed the most potent anti-oxidant activity based on ABTS radical scavenging activity and reducing ability assays, while CA-50E and CA-70E showed the highest DPPH radical scavenging activity. Among major triterpenoid glycosides present in CA, madecassoside and asiaticoside contents were found to be the highest in CA-70E, and madecassic acid and asiatic acid were the highest in CA-50E. In LPS-stimulated RAW 264.7 cells, CA-70E showed the highest TNF-α inhibitory activity, although CA-50E and CA-70E similarly inhibited nitric oxide production. Ethanol extracts significantly inhibited IL-6 and IL-8 production more than water extracts using TNF-α/IFN-γ-stimulated HaCaT cells, indicating its better inhibitory against skin inflammation. Therefore, Chungju-CA EtOH extract, especially 70% EtOH extract, has high physiologically active ingredients and potent anti-oxidant and anti-inflammatory activities, suggesting its industrial application as a functional material.

This study investigated the anti-oxidative and anti-inflammatory activity of unripe fruit peel solvent fractions of the native jeju citrus ‘Hongkyool’ (Citrus tachibana Tanaka) and ‘Pyunkyool’ (C. tangerina Hort. ex Tanaka). The total polyphenol content and total flavonoid content were highest in the butanol fraction of both ‘Hongkyool’ (534.4 mg/g, 431.8 mg/g) and ‘Pyunkyool’ (342.9 mg/g, 415.7 mg/g). In both cultivars, the butanol fraction showed the strong antioxidant activity by DPPH radical scavenging and ABTS radical scavenging. The DPPH radical scavenging of the butanol fraction from ‘Hongkyool’ and ‘Pyunkyool’ was 89% and 64% at a concentration of 1 mg/ml, respectively. The ABTS radical scavenging of the butanol fraction from ‘Hongkyool’ and ‘Pyunkyool‘ was 94% and 85% at a concentration of 1 mg/ml, respectively. We investigated the effect of the anti-inflammatory activity of the ethyl acetate fraction from ‘Hongkyool’ and ‘Pyunkyool’ on LPS-induced NO production, IL-6, iNOS, and COX-2 protein expression in Raw 264.7 cells. At concentrations of 50 and 100 μg/ml of the ‘Hongkyool’ ethyl acetate fraction, the anti-inflammatory effect was excellent. These results suggest that ethyl acetate and butanol fractions from ‘Hongkyool’ and ‘Pyunkyool’ could be useful functional materials, with anti-oxidative and anti-inflammatory properties.

Objectives : Ojeok-san, a traditional herbal formula, has been used for the treatment of cold illness and its related symptoms such as headache, nausea and indigestion. This study was performed to compare effects of water (OJSW) and 70% ethanol extracts (OJSE) of Ojeok-san on inflammation and its related diseases atopy, asthma and obesity in vitro. Methods : We performed HPLC to investigate contents of index components of OJSW and OJSE. We investigated the effects of OJSW and OJSE with an in vitro model, using 5 cell lines, specifically RAW 264. 7, HaCaT, MC/9, BEAS-2B and 3T3-L1. Results : HPLC analysis displayed that the contents of index components were higher in OJSE than OJSW. In lipopolysaccharide (LPS)-treated RAW 264.7 macrophages, OJSE significantly inhibited productions of interleukin (IL)-6, nitrite and prostaglandin $E_2$ ($PEG_2$). In TNF-${\alpha}$/IFN-${\gamma}$-treated HaCaT keratinocytes, OJSE significantly lowered levels of macrophage-derived chemokine (MDC) as well as regulated and normal T cell expressed and secreted (RANTES). OJSE also had a protective effect on inflammatory response by decreasing RANTES secretion in TNF-${\alpha}$-stimulated BEAS-2B cells. Conclusions : We conclude that OJSE could be more appropriate to enhance the biological activities against inflammation and its related diseases, and could be applied as a bioactive material for developing the potent anti-inflammatory agents.

The purpose of this study was to investigate the immuno-stimulatory activity of the high-molecular-weight fraction (HMWF) of Cynanchum wilfordii (CW) extracts obtained by ultrafiltration in murine macrophage RAW 264.7 cells and to assess its immuno-stimulatory effect in mice. Ultrafiltration was performed with polyethersulfone membranes (30 kDa cutoff) in a cross-flow filtration system to obtain the HMWF of CW. The results showed that the HMWF increased the production of various cytokines such as tumor necrosis factor-${\alpha}$, interleukin-6, and nitric oxide in dose-ependent manners. In addition, HMWF treatment increased the relative spleen weight as well as splenocyte proliferation induced by concanavalin A or bacterial lipopolysaccharide in mice. Natural killer (NK) cell activity in the HMWF-treated group was significantly increased compared to that in the control group. These results suggest that the HMWF of CW can support the immune system through secretion of macrophage cytokines, thereby enhancing NK cell activity and murine splenocyte proliferation.

This study was performed to investigate the biological activities of roasted (RE) and non-roasted (NRE) hot water extract samples from Euonymus alatus leaf by measuring DPPH radical scavenging, total polyphenol content, hydroxyl radical scavenging, superoxide dismutase (SOD)-like activity, anti-inflammatory activity, and inhibitory effects on ${\alpha}-amylase$ and ${\alpha}-glucosidase$ in vitro. The $IC_{50}$ values fur DPPH free radical scavenging activity of the NRE and RE hot water extracts were $19.1{\mu}g/mL$ and $21.9{\mu}g/mL$, respectively, and their total polyphenol contents were estimated as 9.6 mg/g for NRE and 10.6 mg/g for RE. Both NRE and RE scavenged the hydroxyl radical in a concentration-dependent manner, but their activities were lower than that of BHA. It was also shown that SOD-like activity was dependent on NRE and RE concentration, and the SOD-like activity of NRE was slightly higher than that of RE. The highest SOD-like activity obtained from NRE was 20% at a concentration of 3 mg/mL. Neither NRE nor RE seemed to have an effect on ${\alpha}-amylase$ and ${\alpha}-glucosidase$ inhibition. Finally, the hot water extracts of NRE and RE significantly decreased the concentration of LPS-induced NO in RAW 264.7 cells, indicating anti-inflammatory activity.

In this study, the bioactivities of ethanol (EEAR) and water extract (WEAR) from the leaf of Aceriphyllum rossii were investigated. In the anti-oxidative activity, IC50 of DPPH radical scavenging activity was respectively 549.86 and $62.14{\mu}g$/mL by EEAR and WEAR. Anti-inflammatory activity of EEAR and WEAR has been evaluated on inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) release by the macrophage RAW 264.7 cells. EEAR and WEAR inhibited inflammatory by 5.58 and 16.85% in 10 mg/mL, respectively. In the anti-diabetic activity, $IC_{50}$ of $\alpha$-glucosidase inhibitory activity was 5.62 and $425.63{\mu}g$/mL by EEAR and WEAR. $IC_{50}$ of $\alpha$-amylase inhibitory activity of EEAR and WEAR was 4,623.87 and over $10,000{\mu}g$/mL, respectively. In the anti-obesity, all lipase inhibitory activity ($IC_{50}$) of EEAR and WEAR was up $10,000{\mu}g$/mL. Finally, EEAR and WEAR exhibited anti-oxidative and anti-diabetic activity. It suggests that Aceriphyllum rossii could be potentially used as a resource of bioactive materials for health functional foods.
