Wounds are commonly created during almost every kind of surgery, trauma and skin diseases. Delayed wound healing affects a plenty of patients and requires prolonged treatments that seriously reduce the quality of life for patients. Skin damage involving large areas or great severity can lead to disability or even death. Wound healing involves a complicated series of actions, of various tissues and cell lineages, concerning inflammation, migration, proliferation, reepithelialization, and remodeling. Sopung-san is reported to have anti-inflammatory effect and has been used for various skin diseases such as allergic dermatitis and atopic dermatitis. In this study, the hypothesis that oral treatment with Sopung-san could enhances healing potential on rat full thickness skin wounds was tested. Twenty young male Sprague-Dawley rats were used for the studies. A full-thickness skin wound was made on the dorsal skin of the rats. Either Sopung-san water extract (SPS) or saline (Control) was orally administrated every day. The wound area was measured and the percentages of wound contraction, wound healed and wound epithelization were calculated. Wound tissue samples were excised following injection for histopathological and immunohistological examination. Wound area in rats of SPS group significantly was decreased compared to Control. SPS group showed significant promotion of wound healing compared to Cotrol group in the percentages of wound contraction, wound healed and wound epithelization. Histopathological examination revealed that SPS induces neo-vascularization potential in wound healing process. SPS treatment in rats significantly accelerated cutaneous wound healing in the neo-vascularization process by increasing VEGF and $TGF-{\beta}1$ synthesis. The results suggest that Sopung-san affects key cellular processes responsible for wound repair and point to a unique potential for this molecule in the therapy of skin wounds, particularly as an angiogenic agent.

This present study was carried out to investigate the biological effects of soybean extracts comparing organic and conventional cultivation. Cellular and molecular analysis was performed to determine anti-oxidative, anti-inflammatory, anti-apoptotic, and anti-inflammatory effects of both soybean extracts. First, we obtained various solvent extracts of soybeans such as water, ethanol, and methanol. Molecular and cellular analysis were performed with 0.1 mg/ml concentration of each solvent extracts. The results of anti-oxidative, anti-inflammatory and anti-apoptotic effects of organic cultivated soybean extracts were prominent than conventional cultivated soybean extracts. However, discrepancy between organic and conventional cultivated soybean extracts was not observed in anti-allergic effects determined by releasing histamine from rat mast cell line, RBL-2H3. Conclusively, organic cultivated soybeans have stronger effects than conventional cultivated soybeans in suppression of inflammation. In addition, organic soybeans could be applied as a functional food ingredient for treatment of chronic inflammation, asthma, and atopic dermatitis with enhanced anti-inflammatory activities.

The worldwide prevalence and severity of allergic diseases including atopic dermatitis and asthma has increased dramatically over the past decade, especially in developed countries. Mast cells are important effector cells in allergic reactions. The purpose of this study was undertaken to investigate the anti-allergic activities of the extract of Duchesnea chrysantha (DCE). DCE was prepared by extracting with 80% ethanol. In the present study, we investigate the effect of DCE on the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, IL-6, IL-8, and histamine in the human mast cell line (HMC-1 cells) and on the scratching behavior in hairless mice. Various concentrations of DCE were treated before the activation of HMC-1 cells with phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187. PMA plus A23187 significantly increased TNF-${\alpha}$, IL-$1{\beta}$, IL-6, and IL-8 production compared with media control. We also show that the increased cytokines such as TNF-${\alpha}$ IL-$1{\beta}$, IL-6, and IL-8 were significantly inhibited by DCE in a dose-dependent manner. Moreover, DCE inhibited the histamine release from HMC-1 cells stimulated by compound 48/80, which promotes histamine release. Futhermore, the administration of DCE reduced the scratching behavior induced by pruritogen (compound 48/80 or histamine) in hairless mice. These results suggest that DCE has a potential use as a medicinal plant for treatment against allergy-related disease.

Objectives Seunggal-tang is one of the prescriptions of oriental herbal medicine, which has been applied to several allergic diseases such as atopic dermatitis. This study was planned to compare differences of anti-allergic effects based on different form of Seunggal-tang by manufacturing differently. Methods Two types herb medicine products were used; aqueous extract (SG-T, Seunggal-Tang) and powder (SG-S, Seunggal-San) which were made from the same mixed formula of Seunggal-tang. To investigate in vitro anti-allergic activities, rat basophilic leukemia (RBL-2H3) cells were treated with SG-T and SG-S for 1 hour, and then stimulated with the phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187. We examined the release of beta-hexosaminidase, as a marker of degranulation, and the releases of tumor necrosis factor (TNF)-alpha and interleukin (IL)-4, as proinflammatory cytokines. Results SG-T and SG-S didn't have effects on cell viabilities in concentrations under 2㎎/㎖. In additionto that, SG-T more inhibited releasing ${\beta}$-hexosaminidase, TNF-${\alpha}$ and IL-4 than SG-S. Conclusions These results indicate that SG-T is more effective against mast cell-mediated allergic reactions than SG-S.

Objectives : Inflammation is one of the self-protective abilities against tissue injury, and it has clinical symptoms like redness, heat, swelling, pain, and loss of function. The purpose of this study is to examine inhibitory effects of Naetakchunkeum-san (NTCKS) on nitric oxide (NO), Prostaglandin E2 (PGE2), inducible NOS (iNOS), cyclooxygenase-2 (COX-2), and phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2), which play a major role in inflammatory response. Methods : The experiment was performed using Raw 264.7 cells pretreated with NTCKS extracts. Cell viability was determined by MTT assay. To evaluate anti-inflammatory effects of NTCKS, we examined NO and $PGE_2$ production in LPS-induced macrophages. We also investigated effects of NTCKS on iNOS, Cox-2, and ERK1/2 expression using western blot. Results : In MTT assay, no cytotoxicity of NTCKS (50, 100, 150, $200{\mu}g/ml$) on RAW 264.7 cell was found. LPS-induced NO production was decreased after treatment with NTCKS (150, $200{\mu}g/ml$)(p<0.05). $PGE_2$ was decreased after treatment with NTCKS (150, $200{\mu}g/ml$)(p<0.05). NTCKS inhibited LPS-induced expressions of iNOS and COX-2 in a dose-dependent manner. Increased phosphorylation of ERK1/2 by LPS was decreased by NTCKS in a dose-dependent manner. Conclusions : According to above experiments, NTCKS may be applied to inflammatory diseases such as atopic dermatitis, rheumatoid arthritis, and inflammatory bowel disease.

Up-regulation of cell adhesion molecules and proinflammatory cytokines contributes to enhanced monocyte adhesiveness and infiltration into the skin, during the pathogenesis of various inflammatory skin diseases, including atopic dermatitis. In this study, we examined the anti-inflammatory effects of butein, a tetrahydroxychalcone, and its action mechanisms using TNF-α-stimulated keratinocytes. Butein significantly inhibited TNF-α-induced ICAM-I expression and monocyte adhesion in human keratinocyte cell line HaCaT. Butein also decreased TNF-α-induced pro-inflammatory mediators, such as IL-6, IP-10 and MCP-1, in HaCaT cells. Butein decreased TNF-α-induced ROS generation in a dose-dependent manner in HaCaT cells. In addition, treatment of HaCaT cells with butein suppressed TNF-α-induced MAPK activation. Furthermore, butein suppressed TNF-α-induced NF-kappaB activation. Overall, our results indicate that butein has immunomodulatory activities by inhibiting expression of proinflammatory mediators in keratinocytes. Therefore, butein may be used as a therapeutic agent for the treatment of inflammatory skin diseases. [BMB Reports 2015; 48(9): 495-500]

Arazyme is a metalloprotease secreted by Aranicola proteolyticus that was previously shown to suppress cytokine expression of keratinocytes and endothelial cells and inhibit histopathological features in an atopic dermatitis-like animal model. However, the regulatory effects of arazyme in other allergic diseases have yet to be elucidated. In this study, we investigated whether arazyme is effective against neutrophil apoptosis in allergic diseases such as allergic rhinitis and asthma. Arazyme inhibited neutrophil apoptosis of normal subjects in a dose-dependent manner. However, the antiapoptotic effect of arazyme was reversed by LY294002, an inhibitor of PI3K, AKTi, an inhibitor of Akt, PD98059, an inhibitor of MEK, and BAY-11-7085, an inhibitor of NF-${\kappa}B$. Arazyme induced activation of NF-${\kappa}B$ via PI3K/Akt/ERK pathway. The anti-apoptotic effect of arazyme is associated with inhibition of cleavage of caspase 3 and caspase 9. Arazyme inhibited constitutive apoptosis of neutrophil in a dose-dependent manner in allergic subjects, and its mechanism was shown to be associated with PI3K/Akt/ERK/NF-${\kappa}B$. The results presented here improve our understanding of neutrophil apoptosis regulation and will facilitate development of drugs for treatment of allergic diseases.

Natural products have received revived interest via traditional remedies or alternative medicine used for the treatment of various diseases. Zanthoxylum piperitum (ZP) has been utilized in traditional medicine for various medicinal purposes. The present study was conducted to evaluate whether ZP modulates allergic inflammation both in vivo and in vitro. We examined the pharmacological effects of ZP on 2, 4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) symptoms in mice. Additionally, in order to clarify the anti-inflammatory mechanisms of ZP, we elucidate the effect of ZP on the expression levels of inflammatory cytokines and nuclear factor-κB (NF-κB) in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). The results demonstrated that ZP attenuated AD clinical symptoms such as erythema, edema and dryness as well as histamine and IgE serum levels in DNCB-induced AD model mice. Additionally, ZP suppressed the expression of inflammatory cytokines and activation of NF-κB in AD-like skin lesions and stimulated HMC-1. These results provide experimental evidence that ZP may be useful candidate for treating allergic inflammation including AD.

Mast cell-mediated allergic disease is involved in many diseases such as anaphylaxis, asthma and atopic dermatitis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. In the present study, the effect of water extract of Gleditsiae Spina (WGS) (Leguminosae), on compound 48/80-induced systemic allergic reaction, anti-DNP IgE antibody-induced local allergic reaction, and histamine release from human mast cell line (HMC-1) cells were studied. In addition, the effect of WGS on phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-induced gene expression and secretion of pro-inflammatory cytokines were investigated using HMC-1 cells. WGS was anally administered to mice for high and fast absorption. WGS inhibited compound 48/80-induced systemic allergic reaction. WGS dose-dependently decreased the IgE-mediated passive cutaneous anaphylaxis. WGS reduced histamine release from HMC-1 cells. In addition, WGS decreased the gene expression and secretion of pro-inflammatory cytokines in PMA plus A23187-stimulated HMC-1 cells. These findings provide evidence that WGS could be a candidate as an antiallergic agent.

Objectives:Spring water is widely known to relax muscles by promoting blood circulation. This study was conducted to analyze theantithrombotic effect of naturally carbonated hot spring water (NCHW) to assess its influence on blood circulation. Methods:Atopic dermatitis was induced in the skin of the mice used in this experiment. NCHW was applied, and the antithrombotic effect was assessed and compared with that of other interventions. The positive control group was treated orally with aspirin. Results:After 3 weeks of exposure to NCHW, the experimental groupshowed a significant antithrombotic effect. NCHW also produced inhibitory responses to both collagen- and ADP-induced platelet aggregation, whereas the group given aspirin reacted only to collagen-induced platelet aggregation. Conclusions:The experiment demonstrated the intrinsic antithrombotic effects of NCHW compared with those of artificially carbonated water, tap water, and aspirin. This result suggests the possibility that NCHW can be used as a supportive and alternative treatment for vascular diseases.
