  • The aim of this study was to evaluate the anti-inflammatory effects of essential oils extracted from the wood of Chamaecyparis obtusa, Pinus densiflora, Pinus koraiensis, and Larix kaempferi. Essential oils were extracted by hydrodistillation, and their chemical components were determined by GC/MS. Major chemical components of these essential oils were ${\alpha}$-cadinol (19.25%), ${\tau}$-muurolol (14.20%), and ${\alpha}$-pinene (13.74%) in C. obtusa; ${\alpha}$-pinene (47.16%), longifolene (14.31%), ${\beta}$-phellandrene (11.78%), and ${\beta}$-pinene (11.02%) in P. densiflora; ${\alpha}$-pinene (13.49%) and longifolene (10.79%) in P. koraiensis, and geranyl linalool (23.58%) and ${\alpha}$-pinene (18.57%) in L. kaempferi. To evaluate the anti-inflammatory effects of essential oils, lipopolysaccharide (LPS)-induced RBL-2H3 mast cells were treated with these essential oils; then, the changes in the mRNA expression level of the cytokines IL-4 and IL-13 were examined. Further, degranulation was evaluated by measuring ${\beta}$-hexosaminidase release. After LPS-induced RBL-2H3 mast cells were exposed to $10^{-7}%$ of all types of essential oils, the gene expression levels of IL-4 and IL-13 within the cells remarkably decreased. The relative mRNA expression level of IL-4 was 69.6% in P. densiflora, 63.2% in P. koraiensis, 55.1% in C. obtusa, and 45.8% in L. kaempferi compared with that in the group treated with LPS. The mRNA expression level of L-13 should a similar trend. The inhibitory rate of IL-13 mRNA expression of P. densiflora, P. koraiensis, C. obtusa, and L. kaempferi was 57.8%, 57.1%, 51.1%, and 34.5%, respectively. ${\beta}$-Hexosaminidase release significantly decreased following the treatment with the four types of essential oils. The rate of ${\beta}$-hexosaminidase release were 38.1% C. obtusa; 33.0% P. densiflora; 27.4% P. koraiensis; and 9.1% L. kaempferi. Among all types of essential oils, that extracted from P. densiflora wood showed the highest anti-inflammatory activity. These results show that the tested essential oils exert an anti-inflammatory effect through the inhibition of degranulation and expression of cytokines.

  • Atopic dermatitis refers to a chronic, recurrent, skin condition, typically typified by itching, inflamed skin. It precedes other allergic diseases, such as asthma, food allergies, and allergic rhinitis, and is usually accompanied by various other immune disorders and secondary symptoms. In this study, we discovered that when treating TNF-${\alpha}$ and IFN-${\gamma}$-stimulated HaCaT cells with various concentrations of Picea wilsonii Mast (PwM) extracts, the cell viability was excellent. In addition, we measured the inflammatory cytokines associated with atopic dermatitis, including IL-6, IL-8, IL-13, and MCP-1. The production of IL-6, IL-13, and MCP-1 decreased in the presence of PwM extracts, whereas there was no significant difference in the production of IL-8. Further studies are necessary to develop an effective cure for atopic dermatitis and inflammation using foreign plant extracts, and PwM efficacy should be determined with an in-depth, objective verification process using protein and mechanism analysis.

  • The aim of the convergence study is to evaluate anti-asthma effects of white ginseng complex extract(WGCE) on OVA-induced allergic asthma in mice. WGCE was administered at 100 mg/kg and 300 mg/kg to mice, where asthma was induced by OVA. Th2 cytokine including IL-4, IL-5 and IL-13 were measured by Luminex. Also, OVA-IgE and eosinophil were measured by haemocytometer and BALF total cells were measured microscope. Production of IL-4, IL-5, IL-13 and OVA-IgE in serum was decreased, respectively, in comparison with control. The eosinophil in whole blood decreased significantly. In addition, WGCE groups showed a decrease in the BALF total cells. These results demonstrated that WGCE decreases the Th2 cytokine and asthma factors. Therefore, we strongly suggest that WGCE could be effectively used as a therapeutic drug based on its anti asthma factors.

  • Background: To increase the pharmacological effects of red ginseng (RG, the steamed root of Panax ginseng Meyer), RG products modified by heat process or fermentation have been developed. However, the antiallergic effects of RG and modified/fermented RG have not been simultaneously examined. Therefore, we examined the allergic rhinitis (AR)-inhibitory effects of water-extracted RG (wRG), 50% ethanol-extracted RG (eRG), and bifidobacteria-fermented eRG (fRG) in vivo. Methods: RBL-2H3 cells were stimulated with phorbol 12-myristate-13-acetate/A23187. Mice with AR were prepared by treatment with ovalbumin. Allergic markers IgE, tumor necrosis factor-${\alpha}$, interleukin (IL)-4, and IL-5 were assayed in the blood, bronchoalveolar lavage fluid, nasal mucosa, and colon using enzyme-linked immunosorbent assay. Mast cells, eosinophils, and Th2 cell populations were assayed using a flow cytometer. Results: RG products potently inhibited IL-4 expression in phorbol 12-myristate-13-acetate/A23187-stimulated RBL-2H3 cells. Of tested RG products, fRG most potently inhibited IL-4 expression. RG products also alleviated ovalbumin-induced AR in mice. Of these, fRG most potently reduced nasal allergy symptoms and blood IgE levels. fRG treatment also reduced IL-4 and IL-5 levels in bronchoalveolar lavage fluid, nasal mucosa, and reduced mast cells, eosinophils, and Th2 cell populations. Furthermore, treatment with fRG reduced IL-4, IL-5, and IL-13 levels in the colon and restored ovalbumin-suppressed Bacteroidetes and Actinobacteria populations and ovalbumin-induced Firmicutes population in gut microbiota. Treatment with ginsenoside Rd significantly alleviated ovalbumin-induced AR in mice. Conclusion: fRG and ginsenoside Rd may alleviate AR by suppressing IgE, IL-4, IL-5, and IL-13 expression and restoring the composition of gut microbiota.

  • Gingival tissue samples were obtained during periodontal surgery or tooth extraction. According to the patient's systemic condition & clinical criteria of gingiva, each gingival sample was divided into three groups. Group 1 (n=8) is clinically healthy gingiva without bleeding and no evidence of bone resorption or periodontal pockets, obtained from systemically healthy 8 patients. Group 2 (n=8) is inflamed gingiva from patients with chronic periodontitis. Group 3 (n=8) is inflamed gingiva from patients with chronic periodontitis associated with type 2 diabetes. Tissue samples were prepared and analyzed by Western blotting. The quantification of $IL-1{\beta}$, MMP-13 and TIMP-1 were performed using a densitometer and statistically analyzed by one-way ANOVA followed by Tukey test. 1. The expressions of MMP-13 and TIMP-1 showed increasing tendency in group 2 & 3 compared to group 1. 2. The expressions of $IL-1{\beta}$ & MMP-13 were showed increasing tendency in group 3 compared to group 2. 3. As $IL-1{\beta}$ levels were increasing, MMP-13 showed increasing tendency in group 3, and although $IL-1{\beta}$ , MMP-13 levels were increasing, TIMP-1 levels were similar expressed comparing to group 2. In conclusion, this study demonstrated that the expression levels of MMP-13 and TIMP-1 had increasing tendency in inflamed tissue. It can be assumed that $IL-1{\beta}$ and MMP-13 may be partly involved in the progression of periodontal inflammation associated to type 2 DM.

  • Background and Objective : Asthma is a chronic inflammatory disease at the mucosa and is associated with excess production of Th2 cytokine and eosinophil accumulation in lung.Gamchomahwang-tangextract(GME) is one of the well known prescription used in oriental medicine for treating asthma. This study was designed to compare the anti-asthmatic effect of GME according to the ratio of 2 compounds.Methods : To examine the effects of GME on asthma, mice were sensitized with 100 ㎍ of OVA and 1 ㎎ of aluminum potassium sulfate(Alum; Sigma) intraperitoneally on day 1 and 15. From day 22, mice were challenged on 3 consecutive days with 5% OVA. The anti-asthmatic effects of GME were evaluated by enhanced pause(Penh), bronchoalveolar lavage fluids (BALF), inflammatory cytokine production and genes expression, serum IgE production. and histological change in lung tissue. GMEⅠ consists of ES and GU in the proportion 2:1(300 ㎎/㎏ group), GMEⅡ consist of ES and GU in the proprtion 4:1(300 ㎎/㎏ group).Results : GMEⅠ,Ⅱ generally inhibited lung inflammation, inflammatory cells infiltration and cytokine production and gene expression such as IL-4, IL-5 and IL-13 in BALF and serum IgE level. GMEⅡ significantly reduced the cytokine production and gene expression such as IL-4, IL-5 and IL-13 in BALF and GMEⅠ decreased cytokine production of IL-4, IL-13 in BALF and gene expression of IL-4, IL-5 in Lung. GMEⅡ potently inhibited the development of Penh and also reduced the number of eosinophil during OVA-induced AHR(airway hyper-reactivity). Overall the results show that GMEⅡ has more effect on inhibiting production, gene expression of cytokine, serum IgE level and development of Penh than GMEⅠ. Consequently, GMEⅡ might be more effective than GMEⅠ at inhibiting allergic asthma on the OVA-induced mice model.Conclusion : These results indicate that GME has a deep inhibitory effects on airway inflammation and hyperresponsiveness in mice model of asthma and that suppression of IL-4, IL-5, IL-13 expression and decrease of IL-4, IL-5, IL-13 production in BALF might contribute this effect. Hence, the results indicate that GME might be useful herbal medicine of allergic asthma. As a result, GMEⅡ mght be superior to GMEⅠ in the aspect of anti-asthmatic effect on the OVA-induced mice model.

  • It has been focused on the importance of the host inflammatory response in periodontal pathogenesis and progression, treatment has been introduced to control the host response and the method, which diminishes production and activity of MMP by doxycycline, has been used in periodontal field. MMP is a proteolytic enzyme which plays a major role in tissue destruction and MMP-1 is secreted in the periodontally healthy tissue, while MMP-8, 9, 13, etc in the inflammatory state. Among these, MMP-13 has been discovered lately and reported to degrade primarily type II collagen. Periodontal ligament (PDL) cell plays a role in destruction of periodontal tissue. This study was to evaluate the effect of doxycycline and mefenamic acid, non-steroidal antiinflammatory drug on MMP-13 mRNA expression in the rat PDL cell. Doxycycline concentration of $1{\sim}100\;{\mu}g/ml$ was added rat PDL cell and cell activity was measured by MIT assay at day 1 and 3. MMP-13 gene expression was evaluated by RT-PCR after PDL cells were pre-treated for 1hour with doxycycline (50 ${\mu}g/ml$) alone or with mefenamic acid ($10^{-6}M$), then added $IL-1{\beta}$(1.0 ng/ml) and incubated for 16-18 hours. The results are as follows: 1. Cell activity decreased Significantly at 24 and 72 hours in 100 ${\mu}g/ml$ (p<0.05). 2. Level of MMP-13 mRNA was in 20.2% increase by $IL-1{\beta}$ and in pre-treating doxycycline group, expression of $IL-1{\beta}$ induced MMP-13 mRNA was inhibited by 31% than $IL-1{\beta}$ treated only. 3. Mefenamic acid did not inhibit on the expression of $IL-1{\beta}$ induced MMP-13 mRNA, while mefenamic acid in combination with doxycycline inhibited the expression by 41% compared to only $IL-1{\beta}$ stimulation. These results suggest that doxycycline synergistically inhibit the expression of $IL-1{\beta}$ induced MMP-13 mRNA in combination with mefenamic acid.
