Objectives : To evaluate experimentally the clinical effect of Bojeongjeongcheon-tang, we observed the cytokines ($IL-1{\beta}$/TEX>, IL-4, IL-5, IL-6, IL-10, TNF-{\alpha},{\;}TGF-{\beta},{\;}IFN-{\gamma}$) and what effect they have on IgE in B cells of a rat. Methods : First of all, we extracted the spleens of healthy Balb/c mice and separated B cells from them. These B cells were cultured with anti-CD40 mAb (500 ng/ml), rmIL-4 (500 U/ml), Bojeongjeongcheon-tang (100 ug/ml, 10 ug/ml, 1 ug/ml). We used rmiL-10 (50 ng/ml) as a control group. Furthermore, we analyzed the expression of IgE, CD23, CD69 and the coherence of HRF in B cells using a flow cytometer. We also analyzed the cytokine gene expression in B cells by reverse transcriptase-PCR. We also measured B cells proliferation using the Liquid Scintillation Counter. Results : In this study, the Bojeongjeongcheon-tang treated group showed a tendency to decrease depending on the density compared with the control group in the expression of IgE+, CD23+, CD69, HRF. All of the Bojeongjeongcheon-tang treated group showed inhibitory effects with $IL-1{\beta}$, IL-4, IL-5 and proliferating effects with IL-6, IL-10, and $IFN-{\gamma}$ on cytokines transcript expression depending on the density. Meanwhile, $TNF-{\alpha}$ increased in all density. In IgE production, there was inhibitory effect on Bojeongjeongcheon-tang (both 100 ug/ml and 10 ug/ml) of significance (p < 0.01, p < 0.05). Also in B cell proliferation, the result revealed an inhibitory effect of Bojeongjeongcheon-tang (both 100 ug/ml and 10 ug/ml), of significance (p < 0.001, p < 0.01). Conclusions : This study shows that Bojeongjeongcheon-tang has an inhibitory effect on the production and activity of B cells. Also it inhibited CD23, IL-4 activity and IgE production and activation. It is obvious that Bojeongjeongcheon-tang treats asthma by inhibiting the production of histamine and HRF, IL-5 and proliferating IL-10. Also Bojeongjeongcheon-tang has some preventive effects on bronchial change by inhibiting $TGF-{\beta}$, which stimulates the bronchial transformation.

Background and Objective : Haeyeol-tang, composed of Houttuyniae Herba, Lonicerae Flos, Taraxaci Herba, and Scrophulariae Radix, is widely used for alleviating the symptom of various kinds of inflammatory pulmonary disease, including asthma and COPD. We want to know whether Haeyeol-tang has an anti-inflammatory effect by analyzing expression of pro-inflammatory cytokines. Materials and Methods : We differentiated the THP-1 cells into macrophage-like cells by treatment with PMA. Inflammation was induced by treatment with LPS and PMA. We found the safe concentration of Haeyeol-tang by using MTS assay and used PD98059 as a negative control for comparison of anti-inflammatory effect of Haeyeol-tang. Results : The RT-PCR analysis results show that the cell survival rate is over 100% within 1 ng/mL to 1 ug/mL of Haeyeol-tang and begins to decrease under 100% at 10 ug/mL. The gene expression of $IL-1{\beta}$, IL-6, IL-8, IL-10, $TNF-{\alpha}$ and $TGF-{\beta}$ levels were down-regulated when Haeyeol-tang was treated at concentrations between 1 ng/mL an 1 ug/mL on monocyte-derived macrophages. Interestingly, 1 ug/mL Haeyeol-tang-treated samples showed that the transcriptional activities of IL-8, $TNF-{\alpha}$, IL-10 and $TGF-{\beta}$ were more down-regulated than those of PD098059 $(TNF-{\alpha}$ inhibitor). At protein level, the ELISA analysis results showed that there were more remarkable (p<0.001) decreases in expression of $IL-1{\beta}$, IL-6, IL-8 and $TNF-{\alpha}$ on both the 1 ug/mL Haeyeol-tang-treated group and the PD98059-treated group than the LPS-treated group. Conclusion : We conclude that Haeyeol-tang has an anti-inflammatory effect by inhibiting expression of pro-inflammatory cytokines and chemokines at mRNA and protein levels. These results may provide us a promising way to care for general inflammatory diseases as well as inflammatory pulmonary disease, including asthma and COPD, with further clinical study.

근관치료의 실패원인 중 중요한 세균으로 알려진 Enterococcus faecalis는 최근에 중요성이 더해지며 많은 연구들이 진행중이다. 여러가지 기전들이 보고되고 있으나 면역반응에 관한 연구는 거의 알려져 있지 않은 상태이다. 본 연구에서는 Enterococcus faecalis의 초음파 분쇄 추출물을 성인의 말초혈액으로부터 얻은 임파구에 적용시켜서 여기서 분비되는 interleukin-2, interleukin-4, transforming growth $factor-\beta1$의 농도를 Enzyme linked immunosorbent assay (ELISA)로 측정하여 비교, 평가하는 것을 목적으로 한다. E. faecalis를 적절한 조건에서 배양한 뒤 초음파 분쇄를 하여 추출물을 얻어냈다. 임파구는 건강한 성인의 말초혈액에서 추출하여 분리하였다. 임파구를 적절한 농도의 mitogen (Phytohemagglutinin: PHA)으로 자극시킨 뒤에 다양한 농도의 E. faecalis 초음파 추출물을 적용시키고 72시간 동안 배양하였다 ELISA를 이용하여 IL-2, IL-4, $TGF-\beta1$의 농도를 측정하였다. 실험결과는 Kruskal-Wallis test, Man-Whitney rank sum test (p < 0.05)를 사용하여 통계처리 하였다. 실험결과 PHA로 처리한 군은 아무것도 처리하지 않은 군에 비해서 IL-2, IL-4의 수치가 유의성 있게 높았다 (p < 0.05). PHA로 처리한 군중에서 고농도와 중농도의 sonic extract of E. faecalis (SEF)로 처리한 군은 그렇지 않은 군에 비해서 IL-2 IL-4의 농도가 유의성 있게 낮았다 (p < 0.05). PHA로 처리한 군중에서 저농도의 SEF로 처리한 군은 그렇지 않은 군과 비교하여 유의할 만한 차이를 보이지 않았다. $TGF-\beta1$의 농도는 모든 군에서 유의할 만한 차이를 보이지 않았다 (p > 0.05). 따라서, E. faecalis의 추출물은 임파구의 IL-2, IL-4의 분비능력을 저하시킨다고 할 수 있다.

T cell immunoglobulin mucin domain (TIM)-3 is an immunomodulatory molecule and upregulated in T cells by several cytokines. TIM-3 also influences mast cell function but its transcriptional regulation in mast cells has not been clarified. Therefore, we examined the transcript level and the promoter activity of TIM-3 in mast cells. The TIM-3 transcript level was assessed by real-time RT-PCR and promoter activity by luciferase reporter assay. TIM-3 mRNA levels were increased in HMC-1, a human mast cell line by TGF-${\beta}1$ stimulation but not by stimulation with interferon (IFN)-${\alpha}$, IFN-${\lambda}$, TNF-${\alpha}$, or IL-10. TIM-3 promoter -349~+144 bp region relative to the transcription start site was crucial for the basal and TGF-${\beta}1$-induced TIM-3 promoter activities in HMC-1 cells. TIM-3 promoter activity was increased by over-expression of Smad2 and Smad4, downstream molecules of TGF-${\beta}1$ signaling. Our results localize TIM-3 promoter activity to the region spanning -349 to ＋144 bp in resting and TGF-${\beta}1$ stimulated mast cells.

Background: This research was performed to investigate the effects of Pulsatilla Koreana NAKAI pharmacopuncture (PPA) therapy on intestinal disease in rats with dextran sulfate sodium (DSS)-induced colitis. Methods: The subjects were divided into five groups : A control group, saline group, pharmacopuncture group PPA1 ($0.2mg/1kg/40{\mu}{\ell}$), pharmacopuncture group PPA2 ($0.5mg/1kg/40{\mu}{\ell}$), and pharmacopuncture group PPA 3($1mg/1kg/40{\mu}{\ell}$). The experimental model of colitis was induced by infection of dextran sulfate sodium (DSS) for eighteen days. After colitis was induced, PPA therapy was practiced on the Chunchu (ST25) once every two days for a total six times. Thereafter Disease Activity Index (DAI), colon length, damage to the colonic mucosa, body weight, IL-6, IL-10, $IL-1{\beta}$, $IFN-{\gamma}$, $TNF-{\alpha}$, $TGF-{\beta}1$, IL-23 and IL-17 were measured. Results: The results were as follows. 1. DAI was significantly decreased in the PPA groups. 2. Colon length was significantly increased in the PPA groups. 3. Damage of colonic mucosa was observed less in the PPA groups. 4. Body weight was significantly increased in the saline group and the PPA groups. 5. The PPA2 group showed a significant decrease in the intensity of IL-6, $IL-1{\beta}$, $IFN-{\gamma}$ and $TNF-{\alpha}$ levels and the mean of IL-23. 6. The PPA3 group showed a significant increase in the intensity of IL-10 and $TGF-{\beta}1$ levels. 7. No significant differences were shown in the mean of IL-17. Conclusion: These results suggest that PPA therapy on Chunchu (ST25) can be used as an effective treatment for inflammatory bowel disease.

Metallothionein, a cysteine-rich stress response protein that is naturally induced by a variety of immunologic stressors, has been shown to suppress autoimmune disorders through mechanisms not yet fully defined. In the present study, we examined the underlying mechanisms by which metallothionein might mediate such regulation of autoimmunity. $Na\ddot{i}ve\;CD4^+$ T cells from metallothionein-deficient mice differentiated to produce significantly less IL-10, $TGF-{\gamma}$, and repressor of GATA, but more $IFN-{\gamma}$ and T-bet, when compared with those from wild-type mice. The levels of IL-4 and GATA-3 production were not different between the two groups of mice. Conversely, treatment with exogenous metallothionein during the priming phase drove $na\ddot{i}ve$ wild-type $CD4^+\;T$ cells to differentiate into cells producing more IL-10 and $TGF-{\beta}$, but less $IFN-{\gamma}$ than untreated cells. Metallothionein-primed cells were hyporesponsive to restimulation, and suppressive to T cell proliferation in an IL-10-dependent manner. Lymphocytes from metallothionein-deficient mice displayed significantly elevated levels of AP-1 and JNK activities in response to stimulation compared with those from wild-type controls. Importantly, transgenic mice overexpressing metallothionein exhibited significantly reduced susceptibility to collagen-induced arthritis and enhanced IL-10 level in the serum, relative to their nontransgenic littermates. Taken together, these data suggest that metallothionein is able to promote the generation of IL-10-and $TGF-{\beta}$-producing type 1 regulatory T-like cells by downregulating JNK-dependent AP-1 activity. Thus, metallothionein may play an important role in the regulation of Th1-dependent autoimmune arthritis, and may represent both a potential target for therapeutic manipulation and a critical element in the diagnostic assessment of disease potential.

The aims of the present study were to confirm that regulation of the PA and environment via TGF-β regulation of sperm by Percoll-separated in porcine uterine epithelial cells. And, it was performed to identify the cytokines (TGF-β1, 2 and 3, TGF-β receptor1 and 2; interleukin, IL-6, IL-8) and PA-related genes (urokinase-PA, uPA; tissue-PA, tPA; PA inhibitor, PAI; uPA-receptor, uPAR) by spermatozoa. The experiment used porcine uterus epithelial cells (pUECs) and uterine tissue epithelial cells, Boar sperm were separated by discontinuous Percoll density gradient (45/90%), and tissues were co-incubated with spermatozoa, followed by real-time PCR. PA activity was measured of sperm by discontinuous Percoll density gradient (45/90%) for 24 hours. To measure viability and acrosome damage of sperm double stained propidium iodide (PI) and SYBR-14 or FITC-PNA were used. In results, binding ratio of Percoll-separated sperm was found no differences, but sperms isolated from 90% Percoll layer reduced PA activity (p < 0.05). when co-cultured sperm selected Percoll in porcine uterus tissues epithelial cells, 90% layer sperm increased TGF-β R1, contrastively tPA and PAI-1 in comparison with control (p < 0.05). 45% sperm was decreased the expression of uPA (p < 0.05). TGF-β decreased PA activity in the supernatant collected from pUECs (p < 0.05). Especially, The group including uPA, PAI-1 were induce sperm intact, while it was reduced in sperm damage when compared to control (p < 0.05). Also, there was no significant difference group of tPA and tPA+I in the dead sperm and acrosome damage compared to control. The expression of tPA and PAI showed a common response. Percoll-separated spermatozoa in 90% layer reduced tPA and IL-related gene mRNA expression. Thus, Percoll-sparated sperm in 90% layer show that it can suppress inflammation through increased expression of TGF-β and downregulation of PA and IL in epithelial cells compared to 45% layer Percoll.
