  • Objectives: Galgeunhaegitang-gamibang(GH) and Samhwangseze-gamibang(SG) has been known that they are helpful for treatment of atopic dermititis clinically, but there is no report about the effect of GH and SG. So, author aimed to investigate the effects of GH and SG on atopic dermititis of NC/Nga mice. Methods : NC/Nga mice were divide into three group : normal, control, and experimental group. Atopic dermatitis was induced in the control and experimental group by spreading DNCB. Then GH was orally administered three times in a week for 8 weeks to the experimental group and SG was spreaded two times in a day for 8 weeks to the experimental group, while the control group was given normal saline. We observed changes of clinical skin severity score, serum IgE, IL-4, IL-4, IL-5, IL-6, IgM, IgGl, $IFN-{\gamma}$ and so on. We used one-way ANOVA test statistically(p<0.01). Results : Clinical skin severities of experiment group in 13 and 16weeks were significantly decreased by 48% and 55% compared to the control group. Serum IgE, IL-4, IL-5, IL-6, IgM, IgGl levels of experimental group were singnificantly decreased compared to the control group. Serum $IFN-{\gamma}$ level of the experimental group was significantly increased against control group. mRNA expression levels of IL-4, IL-5, IL-6 and CCR3 in the skin tissues of experimental group were significantly decreased compared to the control group. In contrary, $IFN-{\gamma}$y mRNA expression level were increased compared to the control group. Histological observation of the ear and skin tissues showed that the extents of inflammation and infiltrated immune cells in the epidermis and dermis of experimental group were highly deminished compared to the control group. Judging from that $IL-1{\beta}$, $TNF-{\alpha}$, IL-6 expression of gene, the effects of inflammatory cytokine revelation were significantly decreased compared to the control group. In the model inducing COX-2 activity in RAW 264.7 cell, COX-2 activity was significantly inhibited depending on the density of GH compared to the control serum. According to cell multiplication, examination of cell toxicity showed that GH is safe at the density of 10, 50, 100mg/l and even 1000mg/l. Conclusion : Accordin to the above results, it is considered that GH and SG is effective treatment for the atopic dermatitis.

  • 아토피 피부염(AD)에 대한 고삼백선피복합방(GBBB)의 치료적 가능성을 증명하기 위해 동물모델에서 다양한 면역 관련 인자들과 조직학적 변화에 대한 GBBB의 영향을 평가하였다. 실험 결과는 다음과 같다. GBBB도포군은 관능평가 결과에서 AD의 개선징후를 나타냈다. GBBB 도포군은 대조군에 비해 혈액 내 백혈구, 호중구, 림프구, 단핵구 면역세포 비율이 54%, 63%, 57%, 86%로 감소되었다. 또한 GBBB도포군은 대조군에 비해 혈청 내 IL-4, IL-5, IL-13, Histamine 및 IgE 생성량이 각각 40%, 80%, 62%, 61%, 57%로 유의성 있게 감소되었다. H&E 염색에서 GBBB 도포군은 대조군에 비하여 비만세포가 피부로 침윤되는 것이 억제되었으며 피부두께 역시 상대적으로 감소되었다. 이 결과를 바탕으로 GBBB는 피부에 직접 도포하는 AD 치료제로서 가능성이 있음이 확인하였다. 후속연구에서는 분자생물학적 연구를 통해 GBBB의 면역조절 기전을 구체적으로 밝히고자 한다.

  • Objective : To investigate the effects of Pyeongwi-san-gamibang on atopic dermatitis, this study measured TEWL(transepidermal water loss), observed scratching behaviors and checked levels of Total IgE, IL-4, IFN-${\gamma}$ and conducted skin biopsy on NC/Nga mice with atopic dermatitis. Methods : NC/Nga mice were challenged with DNCB during 5 weeks to develop atopic dermatitis-like skin lesions. The NC/Nga mice with atopic dermatitis were divided into three groups of control group, PW-d, PW-e group. Once a day for 22 days, Pyeongwi-san-GamiBang extract with water was administered for the PW-d group and the extract with 80% ethanol was administered for PW-e group compared with saline solution for control group. During drug administration, sensitization by DNCB had lasted for three times per week. Results : 1. TEWL had no statistical difference among 3 groups. 2. The scratching behaviors had no statistical difference among 3 groups. 3. The levels of Total IgE in PW-d, PW-e group had a statistically significantly higher than that of the control group although difference between the control group and the PW-d, PW-e group were similar. 4. The level of IL-4 had no statistical difference among 3 groups. 5. The level of IFN-${\gamma}$ had no statistical difference among 3 groups. 6. As the observation of toluidine blue stained lesion, both PW-d and PW-e group had lower level of histamine releasement compared with the control group. Conclusion : Result based on these experiments, Pyeongwi-san-GamiBang on atopic dermatitis-like skin inflammation in NC/Nga mice is not effective. But, as the study showed significantly individual differece, we need to repeat these study after supplementing the object number and modified indicator of clinical severity.

  • Objectives : The aim of this study is to investigate anti-atopic dermatitis effect using ato-tang.Methods : Ato-tang was external treatment to NC/Nga mice for 4 weeks, where atopic dermatitis was induced by DNCB at 1% and 0.4% for 3 weeks. Atopic dermatitis index score was measured using eye observation and picture evaluation. The histopathological change of dorsal skin was observed by hematoxylin and eosin (H&E) staining. Cytokines including IL-4, IL-5 and IL-13 were measured by Luminex or reverse transcriptase polymerase chain reaction (RT-PCR) analysis and immunoglobulin E (IgE) was measured by ELISA reader.Results : The dorsal skin of Ato-tang group showed decrease in erythema, pruritus, dry skin, edema, excoriation, erosion and lichenification level through naked eye observations. Immunoglobulin cell infiltration and the thickness of epidermis were significantly decreased in the dorsal skin compared to control. Production of Th2 cytokines (IL-4, IL-5, IL-13) and IgE level in serum were all significantly decreased, in comparison with control. In addition, mRNA expression level of Th2 cytokines (IL-4, IL-5, IL-13) in spleen was decreased, in comparison with control.Conclusion : The results indicated that external treatment of ato was improved skin barrier function in the symptoms of atopic dermatitis disease. Also, atopic dermatitis factors where cytokine as well as immunoglobulin E in serum and mRNA expression were decreased, respectively, in comparison with control. Therefore, we suggest that ato could be effectively used as a external therapeutic drug based on atopic dermatitis factors.

  • Objectives In this study, we investigated the inhibitory effects of Samhwangsasim-tang (S.H) on the allergic response caused by ovalbumin(OVA) sensitization and challenge in BALB/c mice. Methods The experimental animals were divided into five groups; 1) normal as negative control, 2) OVA-sensitized mice, 3) OVA-sensitized mice treated with 200 mg/kg of S.H 200, 4) OVA-sensitized mice treated with 400 mg/kg of S.H 400, and 5) OVA-sensitized mice treated with 5 mg/kg of Dexamethasone (Dex). Antigen sensitization for allergic mouse model was performed with twice injection of OVA for 2 weeks. After secondary injection, S.H was administrated orally into mice every day for 13 days and the inhibitory effect of S.H on allergic responses was evaluated. Results Treatment of S.H into allergic mice reduced significantly ear edema and infiltration of immune cells in ear tissues induced with OVA challenge in a dose-dependent manner. S.H reduced significantly the serum levels of Total Immunoglobulin(Ig)G and IgE, and particularly inhibited the production of OVA-specific IgE, but not OVA-specific IgG. The serum level of proinflammatory cytokine TNF-${\alpha}$ and Th2-associated cytokine IL-4 also were significantly decreased by S.H adminstration in a dose denpendent manner. S.H attenuated OVA-induced secretion of IFN-${\gamma}$, but not IL-12 which is a cytokine inducing the development of Th1 cells. It also reduced significantly the secretion of IL-4, which is a cytokine inducing the development of Th2 cells, after splenocytes were stimulated with OVA. However the secretion of IL-5 and IL-13 was influenced weakly or a little. Conclusions These results indicate that S.H could reduce the allergic response through inhibition of antigen-specific IgE and Th2-inducing cytokines. It suggest that S.H may be available clinically for the treatment of allergic patients.

  • This study was to evaluate the effect of Samjayangchin-tang (STYCT) on mouse Th1 and Th2 cells' differentiation and ovalbumin (OVA)-induced allergic inflammation. The proliferation of mouse CD4 T cells and the secretion of Th1/Th2 cytokines under the influence of STYCT extract were measured as well as the amount of ${\beta}-hexosaminidase$ in RBL-2H3 cells and the levels of $TNF-{\alpha}$ and IL-6 secretion in Raw264.7 cells. BALB/c mice were orally administered with STYCT extract and simultaneously inoculated with OVA to induce allergic reaction and measure the level of total IgE, OVA-specific IgE and the production of IFN- g, IL-4, IL-5 by the spleen cells. When mouse CD4 T cell were stimulated with anti-CO3 and anti-CD28 for 48 hours in various concentrations of STYCT extract, it decreased proliferation of CD4 cells. CD4 T cells under Th1/Th2 polarizing conditions for 3 days with STYCT resulted in mild decrease of IFN- g in Th1 cells and significant decrease of IL-4 in Th2 cells. STYCT extract had a dose-dependent inhibitory effect on antigen-induced release of ${\beta}-hexosaminidase$ in RBL-2H3 cells. Treatment of STYCT extract on LPS stimulated Raw 264.7 cells showed dose-dependent decrease in IL-6 production. Oral administration of STYCT extract on OVA-induced allergic mice showed an inhibitory effect on the levels of total serum IgE and OVA-specific IgE by 53% and 44%, respectively. Culture of spleen cells with OVA resulted in significant increase of IFN- g by 54% and significant decrease of IL-4 and IL-5 by 42%, and 29%, respectively. The results show that STYCT does not strongly induce mouse T cells to transform into Th1 or Th2 but it has an anti-allergic effect in vitro, and that it also corrects the unbalance between the reactions of Th cells in allergic diseases.

  • NC/Nga mice with contact dermatitis induced using DNCB were applied with GJHB(祛風燥濕解毒方), and its influence on the expressions of IgE, immune related cytokines, and immunoglobulins were tested. The results were obtained as follows ; GJHB significantly redued the production of IgE compared to the control. GJHB significantly reduced the amount of IL-4 within the suspension of spleen cells, but significantly induced the production of $IFN-{\gamma}$, compared to the control. GJHB significantly reduced the production of IL-6 and $TNF-{\alpha}$ in the serum compared to the control. GJHB significantly suppressed the concentration of IgM, IgG2a, IgG2b in the serum. However, no significant decrease of IgG1 was observed. From the results above, GJHB suppressed the intermediate factors during the hypersensitive immune response as well as suppressing the generation of inflammation related cytokines. Therefore, anti-allergic effect of GJHB on the contact dermatitis through immune modulation was confirmed.

  • A rise in the occurrence of allergic diseases is attributed to the dysregulated balance of type 1/type 2 immunity, where type 2 T-helper (Th2) cells predominate over type 1 T-helper (Th1) cells, leading to an abnormally increased production of IgE in response to unharmful antigens. Kimchi, a traditional Korean fermented food, is a rich source of beneficial lactic acid bacteria. In this study, we investigated the ability of Enterococcus faecium FC-K derived from kimchi to induce type I immunity in the presence of Th2 polarizing conditions in vitro and in vivo. Stimulation of mouse peritoneal macrophages with E. faecium FC-K induced the production of tumor necrosis factor alpha, interleukin (IL)-6, and IL-12. Under the in vitro Th2 conditions in which splenic T cells were activated in the presence of IL-4, E. faecium FC-K enhanced the ability of T cells to produce interferon $(IFN)-{\gamma}$. Using the ovalbumin (OVA)-induced allergy model, male BALB/c mice receiving E. faecium FC-K reduced the serum level of total IgE, but not that of OVA-specific IgE. Furthermore, the population of activated splenic B cells during OVA immunization was decreased in E. faecium FC-K-treated mice, accounting for a reduction of total IgE in the serum. Restimulating splenocytes from OVA-immunized mice with OVA ex vivo resulted in an increased production of $IFN-{\gamma}$, with no effect on IL-4, in E. faecium FC-K-treated mice. These observations provide the evidence that E. faecium FC-K can be a beneficial probiotic strain that can modulate the Th2-mediated pathologic response.

  • Scutellariae Radix (Scu.), one of the immune-regulatory substances, is recognized to play the role in the metabolic process of inflammation, allergy and immunity. It has been traditionally used in the Oriental medicine to treat inflammatory bowel diseases (IBD). The purpose of this study was to evaluate the effects of water extracts of Scutellariae Radix on the spleen lymphocyte immune function in the Balb/c female mice treated with dextran sodium sulfate (DSS) to induce colitis. Water extract of Scutellariae Radix (100 mg/kg) and sulfasalazine (50 mg/kg) were administrated orally for 2 weeks of experimental period. Mice were divided into three experimental groups randomly: DSS group (5% DSS was ad libitum for 5 days) as control group, DSS + Scu. (water extracts of Scutellariae Radix for 2 weeks after 5% DSS was ad libitum for 5 days) as experimental group, and DSS + Sulfasalazine group (Sulfasalazine for 2 weeks after 5% DSS was ad libitum for 5 days) as positive control group. Levels of Ig A, Ig E, CD4$^{+}$, CD8$^{+}$, TNF-$\alpha$ and other cytokines were measured. Treatment of DSS for 5 days induced bowel inflammation and the treatment with Scu. water exteract and sulfasalazine significantly recovered the damage. The length of intestine of DSS group was significantly shorter than that of other groups. The serum and fecal concentration of Ig A of SS + Scu group was higher than those of DSS group. The contents of CD4$^{+}$ T cells was higher in the DSS + Scu. group than the other groups and CD8$^{+}$ T cells was the lowest in DSS + Sulfasalazine group. The Ig A level of cultured supernatant of spleen lymphocyte was the highest, while the Ig E level was the lowest in SS + Scu group. The concentration of TNF-$\alpha$, cytokine secreted from the Th1 cell in the supernatant spleen lymphocyte, was the highest in the DSS group and the lowest in the DSS + Scu. group. The concentration of IFN-${\gamma}$ and ll...-12 was lower in the DSS + Scu. group than those of the other groups. The concentration of IL-4 in the supernatant of spleen lymphocyte was the lowest in the DSS + Scu. group but IL-10 was not significantly different. Based on these findings, water extract of Scutellariae Radix exhibited the inhibitory effect via IL-4 production thereby inhibited the production of Ig E and strengthened immune system, and alleviated injury in DSS- induced colitis mice model.
