  • Objectives: Allergic asthma generally presents with symptoms of wheezing, coughing, breathlessness, and airway inflammation. Seonpyejeongcheon-tang (SJT) consists of 12 herbs. It originated from Jeong-cheon-tang (JT), also known as Ding-chuan-tang, composed of 7 herbs, in She-sheng-zhong-miao-fang. This study aimed to evaluate the effects of local delivery of SJT via inhalable microparticles in an asthma mouse model. Methods: Microparticles containing SJT were produced by spray-drying with leucine as an excipient. SJT microparticles were evaluated with respect to their aerodynamic properties, in vitro cytotoxicity, in vivo toxicity, and therapeutic effects on ovalbumin (OVA)-induced asthma in comparison with orally-administered SJT. Results: SJT microparticles provided desirable aerodynamic properties (fine particle fraction of $48.9%{\pm}6.4%$ and mass median aerodynamic diameter of $3.7{\pm}0.3{\mu}m$). SJT microparticles did not show any cytotoxicity against RAW 264.7 macrophages at concentrations of 0.01 - 3 mg/mL. Inhaled SJT microparticles decreased the levels of IL-4, IL-5, IL-13, IL-17A, eotaxin and OVA-IgE in bronchoalveolar lavage fluid (BALF) in mice with OVA-induced asthma. These effects were verified by histological evaluation of the levels of infiltration of inflammatory cells and collagen, destructions of alveoli and bronchioles, and hyperplasia of goblet cells in lung tissues. The effects of SJT microparticles in the asthma model were equivalent to those of orally-administered SJT extract. Conclusion: This study suggests that SJT is a promising agent for inhalation therapy for patients with asthma.

  • In order to evaluate the efficacy of SHT against atopic dermatitis (AD), various immune related cytokines as well as histological comparison were performed in animal models, and the results are described. Clinical skin index of the SHT treated group decreased significantly in weeks 11 and 13, compared to the control group. Also, CD4+ immune cell ratio in the dorsal skin was significantly decreased to 69%, and both epidermal and dermal skin thickness was decreased. Serum IL-4, IL-5, IL-6, IL-13, and TNF-${\alpha}$, which are all important markers of inflammation, were decreased to 64%, 44%, 87%, 48%, and 45%, respectively. The expression of histamine, a chemical transmitter increasingly released during the progression of inflammation, was significantly decreased to 47%. The production of IgE immunoglobulin was significantly decreased to 16% compared to the control group. In conclusion, SHT pacifies the activation of T cells, leading to suppression of both Th2 cytokine overexpression and infiltration of immune cells into skin. As a result, relative thinning of both epidermis and dermis were observed. With the results obtained from in vitro studies, the immune modulatory effect of SHT in AD animal models was experimentally demonstrated. This study should provide solid information to construct EBM and for clinical practice.

  • Atopic dermatitis (AD) is the most common inflammatory pruritic skin disease worldwide, characterized by the infiltration of multiple pathogenic T lymphocytes and histological symptoms such as epidermal and dermal thickening. This study aims to investigate the effect of vinpocetine (Vinp; a phosphodiesterase 1 inhibitor) on a 1-chloro-2,4-dinitrobenzene (DNCB)-induced AD-like model. DNCB (1%) was administered on day 1 in the AD model. Subsequently, from day 14 onward, mice in each group (Vinp-treated groups: 1 mg/kg and 2 mg/kg and dexamethasone-treated group: 2 mg/kg) were administered 100 µl of a specific drug daily, whereas 0.2% DNCB was administered every other day for 30 min over 14 days. The Vinp-treated groups showed improved Eczema Area and Severity Index scores and trans-epidermal water loss, indicating the efficacy of Vinp in improving AD and enhancing skin barrier function. Histological analysis further confirmed the reduction in hyperplasia of the epidermis and the infiltration of inflammatory cells, including macrophages, eosinophils, and mast cells, with Vinp treatment. Moreover, Vinp reduced serum concentrations of IgE, interleukin (IL)-6, IL-13, and monocyte chemotactic protein-1. The mRNA levels of IL-1β, IL-6, Thymic stromal lymphopoietin, and transforming growth factor-beta (TGF-β) were reduced by Vinp treatment. Reduction of TGF-β protein by Vinp in skin tissue was also observed. Collectively, our results underscore the effectiveness of Vinp in mitigating DNCB-induced AD by modulating the expression of various biomarkers. Consequently, Vinp is a promising therapeutic candidate for treating AD.

  • The purpose of this study is to examine the effect of herbal medicine complex (HMC) containing Camellia sinensis L., Duchoesna chrysantha, Houttuynia cordata Thunberg, Poncirus trifoliata Rafinesque on skin inflammation and atopic dermatitis. First, we examined the anti-inflammatory effect of HMC in TNF-α induced human keratinocytes (HaCaT cell). Real-time PCR and western blotting were performed to evaluate the expression of inflammatory cytokines (e.g., iNOS, COX-2, IL-6, IL-8) mRNA and protein. Four-weeks old male NC/Nga mice were treated with 1% 2,4-dinitrochlorobenzene (DNCB) solution and used as an atopic dermatitis mice model. And, HMC (200 mg/kg or 400 mg/kg) was administered directly into the stomach of mice for 4 weeks, and blood or serum analysis, tissue staining were performed after oral gavage. As a result HMC inhibited the mRNA expression of iNOS, COX-2, IL-6, and IL-8, which had been increased by TNF-α in HaCaT cells. In addition, the protein expression was also significantly suppressed in the same way as the mRNA expression results. The in vivo experiment results showed that, HMC administration reduced thickening of the epidermis and infiltration of eosinophil into the skin stratum basale compared to DNCB treatment. In addition, HMC administration significantly reduced the inflammatory cytokines (IL-4, IL-5, IL-6, and IL-13) production and immunocyte (white blood cell, lymphocyte, neutrophil, and eosinophil) count compared to DNCB treatment. Moreover, the serum IgE and histamine level was decreased by HMC administration. These results suggest that HMC can be used as effective herbal medicine extract for skin inflammation and atopic dermatitis. And this study may contribute to the development of the herbal medicine-based drug for the treatment of skin inflammation and atopic dermatitis.

  • Objectives : The aim of this study was to investigate the asthma-suppressive and immuno-regulatory effect of Lepidii Semen Herbal-acupu ncture(LS-HA) at $Joksanmi(ST_{36})$ on ovalbumin(OVA)-induced asthma in mice. Methods : C57BL/6 mice out of all the experimental groups, except the Normal group and the LS-HA group, were sensitized and challenged with OVA. The mice in the LS-HA group and the OVA-LS-HA group were treated with LS-HA(1%) at $Joksanmi(ST_{36})$. The mice in the OVA-Saline group were injected with saline at $Joksanmi(ST_{36})$. The mice in the OVA-Needle-Prick group were treated with a single prick with an injection needle at $Joksanmi(ST_{36})$. LS-HA, saline injection and needle prick were administered for 8 weeks, three times a week. Results : The lung weight and total cells in lung of the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. Total leukocytes and eosinophils in BALF of the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. The collagen accumulation in the lung sections of the OVA-LS-HA group decreased significantly compared with that of the OVA-control group. The concentrations of IL-4, IL-5, IL-13, IgE in BALF and serum of the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. The numbers of $Gr-1^+/CD11b^+$, $CCR3^+$, $CD3e^+$, $CD19^+$, $CD3e^+/CD69^+$cells in the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. The mRNA expressions of $TNF-{\alpha}$, IL-5, IL-4 and IL-13 in lung of the OVA-LS-HA group decreased significantly compared with those of the OVA-Control group. Conclusions: These results suggest that LS-HA at $Joksamni(ST_{36})$ is considered to be effective in treating asthma and to be put to practical use in the future asthma clinic.

  • In this study, the immunological effect of a traditional Korea herbal medicine, Sochungyong-tang (SCRT) that has been widely used for the treatment of various immunological disorders including allergic asthma in Korea, was examined in vitro. In our previous study demonstrated that SCRT decreases the expression of IL-4 mRNA, that plays pivotal role in Th2 cell development, while increases $IFN-{\gamma}{\tilde{a}}expression$, which is one of the key cytokines for Th1 lineage development in Th0 condition. That study strongly implies that SCRT can correct Th2 dominant condition directly affecting to the CD4+ T cell development. Present study designated to further evaluate the SCRT on helper T cell development by monitoring Th1/Th2 specific cytokine secretion patterns in artificially induced Th1 or Th2 polarized condition. The results demonstrated that Th2 cells were dramatically under-populated in Th2 driven condition with SCRT treatment, while Th1 cells were not altered in Th1 skewed condition. Furthermore, under Th2-skewed conditions the levels of and IL-4 were considerably decreased with SCRT treatment. However, the expression of GATA-3, a transcription factor that plays pivotal role in Th2 lineage programming, was not changed with SCRT, suggesting that the suppression of Th2 cell development by SCRT was not mediated by GATA-3. Present study implies that the effect on CD4+ T cell may be the one of key pharmacological effect point for treating IgE medicated allergic asthma by SCRT. These results also suggest that SCRT might be desirable agent for the correction of Th2 dominant pathological disorders.

  • Atopic dermatitis (AD) is a chronic inflammatory skin disorder. Suppression of MAPKs and NF-κB is implicated as a vital mechanism of action of several traditional Chinese medicines for AD therapy. Although overexpression of MAPK mRNA in the skin tissue has been shown in the AD model, the roles of each MAPK in AD pathogenesis have rarely been studied. This study examined the effect of NJK14047, an inhibitor of p38 MAPKs, on AD-like skin lesions induced in BALB/c mice by sensitization and challenges with 1-chloro-2,4-dinitrobenzene (CDNB) on dorsal skin and ears, respectively. After induction of AD, NJK14047 (2.5 mg/kg) or dexamethasone (10 mg/kg) was administrated for 3 weeks via intraperitoneal injection. Following its administration, NJK14047 suppressed CDNB-induced AD-like symptoms such as skin hypertrophy and suppressed mast cell infiltration into the skin lesions. It also reduced CDNB-induced increase in TH2 cytokine (IL-13) and TH1 cytokines (interferon-γ and IL-12A) levels but did not decrease serum IgE level. Furthermore, NJK14047 blocked CDNB-induced lymph node enlargement. These results suggest that NJK14047, a p38 MAPK inhibitor, might be an optimal therapeutic option with unique modes of action for AD treatment.

  • 목적 : Henoch-$Sch{\ddot{o}}nlein$ 자반증에서 항인지질 항체에 대한 연구가 외국에서 몇몇 보고되고 있지만 국내에서는 소아 환자를 대상으로 한 연구가 거의 없는 실정이며 또한 항인지질 항체가 양성인 그룹과 음성인 그룹을 비교하여 연구한 논문은 아직 없는 상태이다. 따라서 한국 소아 Henoch-$Sch{\ddot{o}}nlein$ 자반증에서 항인지질 항체가 양성인 환아의 항인지질 항체의 임상적 의의를 알아보고자 본 연구를 시행하였다. 방법 : 2007년 1월부터 2009년 6월까지 신촌 세브란스 병원 소아청소년과에 내원하여 Henoch-$Sch{\ddot{o}}nlein$ 자반증으로 진단받은 62명의 환아를 대상으로 의무기록을 후향적으로 조사하여 분석하였다. 환아의 일반적인 특징으로 성별, 나이, 복통, 관절통과 자반증 등의 임상 증상을 조사하였고, 검사 소견으로는 백혈구수, 혈색소, 혈소판수, 호산구수, C-반응 단백, 혈침 속도, 단백뇨, 대변 잠혈 검사, 혈청 면역 글로불린(IgG, IgA, IgM, IgE), 혈청 보체(C3, C4), 항핵 항체(ANA), 알부민과 항인지질 항체(루프스 항응고인자, 항카디오리핀 항체, 항${\beta}$ 2GPI 항체) 등을 조사하였다. 결과 : 총 62명의 환아중 남녀 각각 31명이었고 평균 연령은 $6.0{\pm}3.1$세(범위: 1-16세)였다. 루프스 항응고인자 양성인 그룹과 음성인 그룹으로 나누어 비교한 결과 복통, 자반증, 관절통, 신염 등의 임상 증세에서는 두 그룹 간에 통계적으로 유의한 차이가 없는 걸로 나타났으나 검사 소견을 비교하였을 때 양성인 그룹에서 C-반응 단백($4.3{\pm}7.2$ mg/dL vs. $1.3{\pm}1.8$ mg/dL, P=0.035), 혈침 속도($37.5{\pm}26.2 mm/hr vs. $25.1{\pm}22.6$ mm/hr, P=0.039), IgM ($148.1{\pm}48.4$ mg/dL vs. $114.9{\pm}41.5$ mg/dL, P=0.024), C3 ($143.1{\pm}21.9$ mg/dL vs. $129.7{\pm}24.5$ mg/dL, P=0.048), C4 ($30.9{\pm}6.3$ mg/dL vs. $24.9{\pm}7.8$ mg/dL, P=0.002)가 통계학적으로 유의하게 높았다. 결론 : Henoch-$Sch{\ddot{o}}nlein$ 자반증에서 루프스 항응고인자는 29%에서 양성 소견을 보였으며 양성인 그룹에서 염증 인자인 C-반응단백, 혈침 속도 그리고 IgM, C3, C4 수치가 유의하게 높게 측정되었다. 이것은 루프스 항응고인자가 Henoch-$Sch{\ddot{o}}nlein$ 자반증에서 질병의 활성과 병인에 어떤 역할을 수행함을 암시한다고 볼 수 있다.
