This study investigated the effect of the dichloromethane fraction form Katsuwonus pelamis heart on anti-inflammatory responses in lipopolysaccharide-stimulated RAW 264.7 cells and mouse models. Ethanol extract was partitioned with dichloromethane, ethyl acetate, butanol, and water. Among the fractions, the dichloromethane fraction showed a significant decrease in nitric oxide (NO) and pro-inflammatory cytokines [interleukin (IL)-6, $IL-1{\beta}$, and tumor necrosis $factor-{\alpha}$] production compared to ethanol extract. The dichloromethane fraction attenuated the expression of inducible nitric oxide synthase and nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) p65 proteins in a dose-dependent manner. In addition, the expression of phosphorylation of mitogen-activated protein kinases (MAPKs) was also inhibited by the dichloromethane fraction. Moreover, the administration of 10, 50, and 250 mg/kg body weight-dose dependently inhibited the formation of edema by croton-oil and the application of dichloromethane (2 mg/ear) significantly reduced epidermal and dermal thickness and the infiltrated mast cell numbers. Therefore, the dichloromethane fraction exhibited an anti-inflammation effect by inhibiting $NF-{\kappa}B$ and MAPK signaling activation in macrophages.

The anti-inflammatory effect of Sargassum patens C. Agardh ethanol extract (SPEE) was examined based on the lipopolysaccharide (LPS)-induced inflammatory response in this study. SPEE treatment was not cytotoxic to macrophages compared to the control. The production of NO was suppressed by SPEE by approximately 28% at $100{\mu}g/ml$, and levels of interleukin-6, tumor necrosis $factor-{\alpha}$, and $interleukin-1{\beta}$ decreased in a dose-dependent manner. In addition, the expression of inducible nitric oxide synthase, cyclooxygenase-2, and nuclear $factor-{\kappa}B$ was suppressed by SPEE treatment. In vivo, croton oil-induced mouse ear edema was attenuated by SPEE and the infiltration of mast cells into the tissue decreased. Based on these results, SPEE inhibits the release of LPS-induced pro-inflammatory cytokines and mediators, suggesting that SPEE is a potential agent for anti-inflammatory therapies.

This study was carried out to demonstrate the anti-inflammatory effect of tuna oil (TO) using LPS-induced inflammation responses and mouse models. First, nitric oxide (NO) and pro-inflammatory cytokines levels were suppressed up to 50% with increasing concentrations of TO without causing any cytotoxicity. Also, the expression of a variety of proteins, such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and nuclear factor kappa B (NF-κB), was suppressed in a dosedependent manner by treatment with TO. Furthermore, TO also inhibited the phosphorylation of mitogen-activated protein kinases (MAPKs), including c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK), and p38 protein kinase (p38). Moreover, in in vivo testing the formation of ear edema was reduced at the highest dose tested compared to that in the control, and a reduction of ear thickness and the number of mast cells was observed in histological analysis. In acute toxicity test, no mortalities occurred in mice administrated 5,000 mg/kg body weight of TO over a two-week observation period. Our results suggest that TO has a considerable anti-inflammatory property through the suppression of inflammatory mediator productions and that it could prove to be useful as a potential anti-inflammatory therapeutic material.

Purpose : Panax ginseng(PG) is considered to have salutary effects and stimulant actions on physical capacity. However, the effects of PG on the inflammatory cytokine secretion and hypoxia condition are still not understood. This study wasto elucidate the effect of PG on inflammatory cytokine secretion such as interleukin (IL)-1, IL-6, granulocyte macrophage colony stimulating factor (GM-CSF), and tumor necrosis factor $(TNF)-{\alpha}$. Also, the effects on the expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1 (HIF-1) were measured. Methods : The water extract of PG was administrated to HMC-1 cells before phorbol myristate acetate (PMA)+A23187 treatment. $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, GM-CSF, and VEGF secretion were measured by a modified enzyme-linked immunosorbent assay (ELISA). HIF-1 activation was measured by transcription factor enzyme-linked immunoassay (TF-EIA) Results : PG significantly decreased secretion of $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, and GM-CSF in PMA+A23187-induced HMC-1 cells. VEGF secretion was not changed but HIF-1 activation was decreased by the treatment of PG. Conclusions : PG inhibited the secretion of inflammatory cytokines, which impliesPG might contribute to treatment of mast cell-mediated inflammatory disease. Also, PG inhibited PMA+A23187-induced $HIF -1{\alpha}activation}$ and DNA-binding activity for HIF-1. Therefore, these data demonstrate that PG modulates inflammatory cytokines through inhibition of $HIF-1{\alpha}activation}$ activation.

Objectives : Since ancient times, Koreans have applied medicinal spabaths for treatment of various diseases. The objective of this study was to investigate the effect of strontium, one of the common ingredients of such baths, experimentally on acute skin barrier damage. Materials and Methods : Male hairless mice, average weight 20g, were divided into six groups. Each group consisted of five mice. The first was the normal, non-treated group. The second was the control group with acute skin barrier damage intentionally induced by TS. The third was the Ba-Sr1 group bathed in 1mg/L strontium chloride before and after inducing acute skin barrier damage by TS. The fourth was the Ba-Sr7 group bathed in 7mg/L strontium chloride before and after inducing acute skin barrier damage by TS. The fifth was the Sr1 group bathed in 1mg/L of strontium chloride only after intentionally inducing acute skin barrier damage by TS. The sixth was the Sr7 group bathed in 7mg/L of strontium chloride only after intentionally inducing acute skin barrier damage by TS. External changes of skin, skin erythema level, transepidermal water loss level, and GOT and GPT level of each group were checked immediately before and after TS, 3 hrs, 5 hrs and 24 hrs after inducing acute skin barrier damage. Then, tissue samples were made and examined for damage to epithelial cells, stratum corneum, change of mucous polysaccharide in dermis and amount of mast cells. Statistical analysis was performed by one way-ANOVA, Scheffe and Duncan for a post hoc test and pairwise comparison for comparing for difference between each time. Statistical significance was achieved if the probability was less than 5% (p<0.05) Results : 1. From skin erythema and TEWL level indicating the function of the skin barrier, we can know that it is helpful to the skin barrier to bathe in a water solution including a low concentration of strontium. 2. In the control group with acute skin barrier damage induced by TS, skin barrier damage persisted until 3-5 hrs and recovered after 5-24 hrs. Differently from the control group, in the case of taking a bath in a water solution including strontium, skin barrier damage recovered after only 3-5 hrs. Therefore, the bath with a water solution including strontium can promote recovery of the skin barrier. 3. Bathing in water solution including a higher concentration of strontium was more beneficial to recovery of skin barrier damage. 4. There was no influence on serum GOT and GPT from bathing in a water solution including strontium. Conclusions : The strontium was effective for recovery and mitigation of acute skin barrier damage induced by tape stripping. I suggest that strontium (Sr) can be used as an external treatment medicine, addedinto bath water to treat acute skin barrier damage.

The roots of Opuntia humifusa (OHR) were extracted with 80% aqueous MeOH and the concentrated extract was partitioned with EtOAc, n-butanol and $H_2O$, successively. The fractions were tested using DPPH and ABST radical scavenging method. The all fractions showed potent scavenging effects. The scavenging effect of the EtOAc fraction was higher than the other fractions, with $IC_{50}$ values as DPPH; $77.0{\pm}1.38{\mu}g/mL$, ABTS: $26.3{\pm}2.02{\mu}g/mL$. And, we investigated anti-inflammatory activities by examining the effects of the OHR fractions on pro-inflammatory cytokine release in the human mast cells (HMC-1). Treatment with OHR fractions clearly reduced the release of the proinflammatory cytokines tumor necrosis factor-alpha (TNF-${\alpha}$), interleukin (IL)-$1{\beta}$, interleukin (IL)-6 and interleukin (IL)-8) in PMACI-stimulated HMC-1 cells. The results showed the potential of OHR as an excellent antioxidant substance and inhibiting inflammatory mediators. Therefore, OHR may be used as a therapeutic approach to various inflammatory diseases.

Leonuri Fructus, a semen of Leonuri Herba, has been used for the treatment of menstrual disorders such as amenorrhea, dysmenorrhea and leukorrhea and for the remedy of hyperemia. The present study was conducted to evaluate the anti-inflammatory effects of the Leonuri Fructus extract (Leonurus japonicus Houtt. EtOH extract; LJE) in vivo and in vitro. In vitro study, the MTT assay for cell viability was conducted to determine the non-cytotoxic concentration of LJE treatment in media. The levels of NO were measured with Griess reagent. Pro-inflammatory cytokines were detected by ELISA method. The inflammation-related proteins of this study were detected by immunoblot anlaysis. The increases of NO production and iNOS expression were detected in LPS-treated cells compared with control, but LJE attenuated the increases of NO and iNOS by LPS. LJE reduced the production of TNF-${\alpha}$ and IL-$1{\beta}$ induced by LPS stimulation. LJE suppresses the signaling pathways of NF-${\kappa}B$ and MAPKs in LPS-induced macrophage cells. In vivo study, carrageenan-induced hind paw acute edematous inflammation rat model was used for evaluation of anti-inflammatory activity of LJE. LJE significantly inhibited the increases of hind paw swelling, skin thicknesses and inflammatory cell infiltrations, and decreased the numbers of mast cell induced by carrageenan injection. These results suggest that LJE has an anti-inflammatory therapeutic potential, which is mediated through modulating NF-${\kappa}B$ activation and MAPK phosphorylation. Inhibition of the rat paw edema induced by carrageenan is considered as direct evidence that LJE may be a useful source to treat inflammation.

To evaluate the skin aging inhibition effect of fermented Reynoutria elliptica, skin aging model was produced by the irradiation of UVB to hairless mice for 5 weeks. The skin erythema index for the positive control (PC), not fermented Reynoutria elliptica extract (NFR), and fermented Reynoutria elliptica extract (FR-500, 1000, 2000) groups were lower than that of the control group. However, both lipid and water capacity for the PC and FR groups were higher than those of the control group. Collagen fibers in dermis of the FR groups were almost intact with a regular arrangement which were similar to the normal (NO) group. Also, relatively much less number of mast cells and inflammatory cells were found in FR groups. The skin TBARS contents and XO activity in the FR group were significantly lower than the control group. The activities of GSH, SOD and CAT for the FR groups were significant higher than the control group. Therefore, fermented Reynoutria elliptica extract can be practically useful for the prevention or improvement of skin aging in terms of health promotion and beauty for the people.

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.
