Background : Asthma is considered to be an inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia. Production of cytokines by bronchial epithelial cells may contribute to the local accumulation of inflammatory cells in patients with bronchial asthma. In many recent studies molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objective : We aimed to identify the effects of Sochongryong-tang on Serum IL-4, IL-5, $IFN-{\gamma}$ in asthmatic patients. Material and Methods: The subjects consisted of 15 patients with asthma who had been treated with Sochongryong-tang for two weeks from February 2001 through June 2001. Sochongryong-tang is an herbal decoction which has traditionally been used as a therapeutic agent for asthma. Results : The serum IL-4 in asthmatic patients was increased significantly compared to the serum IL-4 in the normal control group. However, the serum IL-5, $IFN-{\gamma}$ in asthmatic patients showed no significant difference from the serum IL-5, $IFN-{\gamma}$ in the normal control group. The patients were treated with Sochongryong-tang for two weeks with no significant difference in the serum IL-4, IL-5, and $IFN-{\gamma}$. Conclusion : This study shows that the serum IL-4 may be a new therapeutic target of asthma. Further long-term studies must be made in a larger number of asthmatic patients.

Objectives Previous studies have found out that Forsythiae Fructus (FF) extracts have anti-atopic activities by in vitro experiment. In order to understand more about FF extracts' benefit, we subdivided FF extracts depending on systematic fractionation method by using Methylene chloride (MC), Ethyl acetate (EtOAc), n-BuOH and n-hexane (n-Hx). This study is designed to examine the effect of FF fractions on the PMA- ionomycin-induced activation of RBL-2H3 mast cell lines in vitro and on the DNCB-induced activation of NC/Nga mice in vivo. Methods For this study, we examined IL-4, IL-13 production by ELISA analysis, IL-4, IL-13, IL-31, IL-31RA and TNF-${\alpha}$ mRNA expression by real-time PCR and manifestations of AP-1 and MAPKs transcription factors by western blotting in vitro. Through in vitro experiment, we selected FF n-BuOH fraction that seems the best effective in atopic dermatitis then induced it on NC/Nga mice by DNCB. We measured mice's WBC, eosinophil and neutrophil in heart blood, IL-4, IL-5, IFN-${\gamma}$ in the spleenocyte culture supernatant, the absolute cell numbers of CD4+, CD8+, B220+CD23+, CD3+CD69+ and Gr-1+CD11b+ in the PBMCs, ALN and dorsal skin, IL-5, IL-13, IL-31, IL-31RA in the dorsal skin by real-time PCR and the distribution of immune cells by H&E on dorsal skin and ANL and toluidine blue staining on dorsal skin. Results FF n-BuOH fraction suppressed IL-4, IL-13 production and mRNA expression of IL-4, IL-13, IL-31, IL-31RA and TNF-${\alpha}$. Results from the western blot analysis showed that FF n-BuOH fraction reduced the activation of the mast cell specific transduction factors involved in AP-1 by suppressing JNK and ERK phosphorylation. In the gross, atopic dermatitis induced by DNCB in NC/Nga mice were improved by oral administration of FF n-BuOH fraction. Oral FF n-BuOH fraction also decreased the level of IgE in mice's serum and the level of IL-4 and IL-5 in the spleenocyte culture supernatant, cell numbers of CD8+, B220+CD23+ in the PBMCs, CD4+ in the ALN and CD4+, Gr-1+CD11b+ in the dorsal skin and suppressed mRNA expression of IL-5, IL-13, IL-31, IL-31RA in the dorsal skin. Histological examination showed that infiltration levels of immune cells in atopic dermatitis induced NC/Nga mice were improved by FF n-BuOH fraction. Conclusions FF n-BuOH fraction can reduce pruritus by suppressing IL-31, IL-31RA secretion and modulate molecular mediators and immune cells associated with atopic dermatitis induced in NC/Nga mice which may have played a significant role in recovering atopic dermatitis symptoms.

Purpose: The aim of this cross-sectional study was to investigate the effect of scaling and root planing (SRP) on the expression of anti-inflammatory cytokines (interleukin [IL]-4, IL-9, IL-10, and IL-13) in the gingival crevicular fluid (GCF) of electronic cigarette users and non-smokers with moderate chronic periodontitis (CP). Methods: Electronic cigarette users and non-smokers with CP were included in the study. Full-mouth plaque and gingival indices, probing depth (PD), clinical attachment loss (CAL), and marginal bone loss (MBL) were assessed. The GCF was collected, and its volume and levels of IL-4, IL-9, IL-10, and IL-13 were assessed. These parameters were evaluated at baseline and 3 months after SRP. The sample size was estimated, and comparisons between groups were performed. P<0.05 was considered to indicate statistical significance. Results: Thirty-six electronic cigarette users (47.7±5.8 years old) and 35 non-smokers (46.5±3.4 years old) with CP were included. At baseline, there were no differences in plaque index (PI), PD, CAL, MBL, and GCF IL-4, IL-9, IL-10, and IL-13 between electronic cigarette users and nonsmokers. At the 3-month follow-up, there were no significant differences in PI, gingival index (GI), PD, CAL, and MBL in electronic cigarette users compared to baseline, while there were significant reductions in PI, GI, and PD among non-smokers. At the 3-month follow-up, GCF IL-4, IL-9, IL-10, and IL-13 levels were significantly elevated in both groups (P<0.05) compared to baseline. The increases in GCF IL-4, IL-9, IL-10, and IL-13 levels were significantly higher in non-smokers (P<0.05) than in electronic cigarette users at the 3-month follow-up. Conclusions: Levels of GCF IL-4, IL-9, IL-10, and IL-13 increased after SRP in electronic cigarette users and non-smokers with CP; however, the anti-inflammatory effect of SRP was more profound in non-smokers than in electronic cigarette users.

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.

Background and Objective : Atractylodes japonica (AJ) is a commonly-used herbal medicine in Asian countries such as Korea, China and Japan. The present study was designated to evaluate the direct effects of AJ on helper T cell activities and on Th1/Th2 lineage development in vitro. Materials and Methods : Spleen cells from 8-week BALB/c mice were cultured in CR extracts containing medium without activation for 24 hours and with activation for 48 hours. CD4+ T cells were isolated and analyzed for mRNA expression levels of INF-$\gamma$, IL-4, T-bet and GATA-3 by RT-PCR and secretion cytokines levels of INF-$\gamma$, IL-2, IL-4, IL-5 and IL-10 by ELISA. Results : The results demonstrated that AJ had no mitogenic effects on unstimulated CD4+ T cells, but augmented CD4+T-cell proliferation upon activation with anti-CD3/anti-CD28 antibodies in a dose-dependent manner. AJ treatment significantly increased CD4+ T cell population and IFN-$\gamma$ expression was significantly enhanced, while IL-4 expression significantly decreased. In addition, in vitro Th1/Th2 polarization experiments revealed that AJ enhanced IFN-$\gamma$ secretion in Th1 cells, but reduced the IL-4 in Th2 cells in dose-dependent manner. Conclusion : These results suggest that AJ treatment could be a desirable alternative therapy for the prevention or correction of Th2 dominant pathological disorders, such as allergy and asthma.

Objectives : We investigated to find the relationship between single-nucleotide polymorphism (SNP) of IL4R, IL-10 and bee venom therapy efficacy in patients with RA treated with bee venom for 8 weeks. Methods : Korean RA patients (n=114) and healthy subjects (n=109) were included in this prospective study. Korean bee venom was dissolved in saline (diluted 1:3000) and administrated into acupuncture points. Bee venom therapy was applied twice a week and continued for 8 weeks. The clinical response was evaluated using various assessments before and after treatment. Disease severity was measured by determining the number of tender joints and swollen joints. Laboratory studies included ESR, CRP, and rheumatoid factor. Genotyping for IL-4R and IL-10 polymorphism was done by pyrosequencing analysis. Results : 1. In IL4R genotypes, there was significant difference between RA ptitients tind controls group. 2. In IL4R genotypes, there was significant difference among Good, Mild and Bad responders to in RA patients, but in the frequency of alleles and carriers, there were no significant difference. 3. There was no significant difference between RA patients and controls group in IL-10 gene genotypes. 4. In IL-10 genotypes, there was no significant difference among Good, Mild and Bad responders to in RA patients. 5. There was no significant difference in the improvement of ESR, CRP and KHAQ scores after bee venom therapy in RA patients among the IL4R or IL-10 genotypes. Conclusions : In IL-4R genotypes, there was significant difference between RA patients and control group, and among Good, Mild and Bad responders in RA patients. However, in IL-10 genotypes, there was no significant difference between RA patients and controls group and among Good, Mild and Bad responders in RA patients.

Canine juvenile cellulitis (CJC) is a well-recognized lymphocutaneous disease that is seen in young dogs. CJC seemed to be immunologic disorder and may have a hereditary aspect. Exact pathogenesis and cytokine regulation on the immune system of CJC are not clear. CJC was diagnosed in two puppies hospitalized in Veterinary Teaching Hospital of Chungbuk National University. To investigate the cytokine regulation on CJC, RT-PCR was performed with CJC affected dogs. RT-PCR 1 was performed with whole blood sample (CJC-B) and fine needle aspirates of the inguinal lymph node (CJC-LN) from case 1-dog, which included $TNF-\alpha,$ $IL-1\beta,$ $IFN-\gamma,$ IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12 and $\beta-actin.$ Blood sample from a normal dog (N-B) served for a negative control of RT-PCR 1 (case 1). $IFN-\gamma,$ IL-2, IL-4, IL-5, IL-8, IL-10 and IL-12 transcripts were not expressed in all sample. $TNF-\alpha$ and $IL-1\beta,$ were not transcripted from CJC-B but from CJC-LN. On RT-PCR 2 (case 2), submandibular lymph node aspirates were used and $TNF-\alpha,$ IL-10, $IFN-\gamma$ and $IL-1\beta$ were expressed. $TNF-\alpha,$ 1L-10 and $IFN-\gamma$ were secreted from activated macrophages enhance the inflammation in tissue. These results imply that abnormally increased macrophages secret $TNF-\alpha$ and $IL-1\beta$ in the affected lymph nodes, which attract neutrophils and cause inflammation in CJC.

이 연구의 목적은 신체활동이 마이오카인 발현에 미치는 영향을 보고자 문헌고찰을 하였다. 신체적인 활동은 제2형 당뇨, 심혈관질환, 대장암, 치매 및 우울증과 같은 질환을 예방하는 역할을 하고 있다. 그리고 마이오카인(myokine)은 운동 훈련에 의해 분비되는 호르몬으로 뇌성장이나 알츠하이머 같은 질환 예방에 도움을 준다. 운동수행과정에서 수축하는 근육으로부터 분비되는 항염증 마이오카인의 생성과 대사 조절에 필요한 분비 활성화가 건강증진에 중요한 요인으로 보고 있다. 인체 골격근에서 분비되는 마이오카인 가운데 IL-4, IL-6, IL-7, IL-8, IL-15 등은 근육비대(hypertrophy)와 세포(myogenesis) 및 혈관생성(angiogenesis) 등의 조절에 관여한다. IL-6는 AMPK 활성화로 인한 대사중 지방 산화를 촉진시키는 작용을 하고, IL-1Ra, IL-10 과 sTNF-R 는 염증성 싸이토카인 $TNF-{\alpha}$의 분비를 억제한다. IL-15는 저항 운동시 근수축을 통한 발현량이 증가하어 근육 성장의 중요 합성요인으로 작용한다. 한편 IL-7 및 IL-8도 신호 전달 수용체 C-X-C를 통해 혈관신생을 촉진시킨다.

The purpose of this study is to determine whether the clinical activity of patients with atopic dermatitis(AD) correlate with their serum cytokine levels. 86 patients with AD were treated with KHS, YMH and GHT. On each visit to the clinic, their skin status was evaluated using the SCORAD index and serum IL-4, $IFN-{\gamma}$, IL-12, IL-13, IL-2 and IL-10 were measured by ELISA. After oral administration of herbal medicine, patients' skin status and subjective parameters such as pruritus and sleeplessness were significantly improved according to regression analysis. In particular, patients aged 0-9 showed stronger responses to treatment, which implies that the younger patients aged, the easier the treatment by herbal formula became. In analysis of the type of chosen herbal medicines, YMH treated group showed a stronger response in reduction of affected lesion, intensity of a lesion and subjective symptoms, while KHS treated group showed the least reduction. The levels of serum IL-4, $IFN-{\gamma}$ and IL-2 correlated with disease activity. Moreover, in patients under 0-9, the IL-4 level had a corrleation with disease activity; patients under 10-19 showed a correlation between the levels of IL-4 and IL-2 and disease activity; patients under 20-29 showed a correlation between the levels of IL-2, IL-12 and $IFN-{\gamma}$ and disease activity. In comparison with chosen herbal medicines, the groups treated with YMH or GHT treated group showed a correlation between the levels of IL-4, IL-12 and IL-2 and disease activity while KHS treated group did not. Our data suggest that serum levels of IL-4 and IL-13 are good indicators of clinical improvement in treating AD.

1. 연구배경 및 목적 사상의학(四象醫學)에서 열다한소탕(熱多寒少湯)은 태음인(太陰人)의 뇌경색증 급성기에 매우 빈번하게 사용되는 처방 중 하나이다. 그래서 저자는 열다한소탕(熱多寒少湯) 투여에 따른 뇌경색증 환자의 면역계 특히 세포활성문질만계의 변화에 대해 연구하기로 하였다. 2. 방법 원광대학교 광주한방병원 사상의학과에 입원한 뇌경색증 한자 8인(남자 3명, 여자 5명)을 대상으로 하여, 내원 당시와 2-4주간의 열다한소탕 투여 후의 세포활설물질망계의 변화를 추적하였다. 또한 정상태음인의 말초혈액단핵구를 채취하여 리포다당체 처리시의 변화를 열다한소탕(熱多寒少湯) 전처리 유무에 따라 비교 분석하였다. 3. 결과 IL-2 혈장 농도는 정상 대조군보다 환자군에서 더 낮았다. $IFN-{\gamma}$의 경우 역시 정상 대조군보다 약간 낮았으나 통계학적 유의성은 없었다. IL-4, IL-6, IgE의 혈장중 수준은 정상 대조군에 비해 환자군에서 현저히 상승되어 있었다. 그러나, 2-4주간의 열다한소탕(熱多寒少湯) 투여후 $IFN-{\gamma}$, IL-2의 혈장 중 수준은 현저히 상승되었고, IL-4, IL-6, Ig E 수준은 현저히 억제되었다. 한편 정상 태음인의 말초혈액단핵구에 리포다당체 처리를 한 후 $IFN-{\gamma}$, IL-2, IL-6가 상승되었으나, 열다한소탕(熱多寒少湯) 전처리를 한 경우에서는 이들 물질의 생성이 유의하게 억제되었다.
