연구목적: 포유류의 착상은 배아가 모체의 자궁벽에 매몰되는 현상으로 부착과 침투 과정을 거쳐 진행되며, 이 과정은 스테로이드 호르몬, 성장인자, 세포점착분자, 그리고 cytokine 등의 상호작용으로 이루어진다. 이 시기에 Interleukin-1 (IL-1)과 leukemia inhibitory factor (LIF) 등이 발현되는 것으로 알려져 있다. 본 실험에서는 이들의 발현이 착상과정에 어떠한 역할을 하는지 그 상관관계를 알아보고자 하였다. 재료 및 방법: 착상 전후의 배아와 자궁내막세포에서 LIF 유전자의 발현양상과 $IL-1{\beta}$와 IL-1 receptor antagonist (IL-1ra)를 처리한 LIF 유전자의 발현양상을 역전사중합효소연쇄반응 (RT-PCR)을 통해 비교하였다. 결과: 배아에서의 LIF 유전자 발현은 in vivo와 in vitro 모두에서 상실기와 포배기에 발현되었고, 자궁내막에서는 임신 1일과 4일째에 발현되었는데, 상실기보다는 포배기에, 그리고 임신 1일보다는 착상시기인 4일째의 자궁내막세포에서 발현양이 많은 것으로 나타났다. 자궁내막세포를 배양한 경우 LIF 유전자는 in vivo에서의 발현양상과 동일하게 임신 1일과 4일에 발현되었으며, 배양액에 $IL-1{\beta}$(500pgml)를 처리하였을 경우 LIF 유전자가 초기 임신 (1~5일) 중 발현되는 것으로 나타났다. 2-세포기 배아의 배양시에 $IL-1{\beta}$를 처리한 경우 8-세포기부터 LIF 유전자가 발현되었으며, 또한 IL-1ea(60 ng/ml)를 배양액에 첨가하였을 경우에는 임신1일째 자궁내막에서는 LIF 유전자가 발현되지 않은 반면, 임신 4일째의 자궁내막세포와 상실기, 포배기 배아 모두에서 LIF 유전자 발현이 감소하는 경향을 보였다. 결론: 이러한 결과는 착상 전후 배아와 자궁내막세포에서 IL-1에 의해 LIF 유전자 발현이 조절되며, 그 결과 착상에 영향을 줄 수 있다는 것을 의미한다. 또한 배아와 자궁내막세포에서 IL-1이 LIF 유전자 발현에 영향을 주는 것으로 보아 착상을 위해 IL-1과 LIF의 상호작용이 중요한 요인이라는 것을 확인할 수 있었다.

Purpose: The purpose of our study was to determine the concentrations of cytokines in ACL deficient knee, the changes of cytokines from injury as the time progressed, and changes of cytokines after ACL reconstruction. Materials and Methods: Twenty-five patients with ACL-injured knee were enrolled. Synovial fluid lavages were collected at the time of surgery. Before surgery, twenty-five patients were aspirated synovial fluid from their injured and uninjured knees. Twelve patients were aspirated synovial fluid after 9 months postoperatively. The samples were analysed for $IL-1{\beta},\;TNF-{\alpha}$, MMP-3, IL-6 and TIMP-1 using ELISA. Results: The $IL-1{\beta}\;and\;TNF-{\alpha}$ concentrations were below detectable ranges in all uninjured knees and ACL ruptured knees. There were no significant difference between the mean concentrations of the uninjured and ACL injured knees for TIMP-1 and IL-6. The mean concentration of MMP-3 in ACL injured knees was significantly higher than in the uninjured knees. In the 12 cases after 9 months postoperatively, the mean concentration of MMP-3 was no significant difference between preoperative cytokine levels. Conclusion: The concentration of MMP-3 was only higher in the ACL injured knee than uninjured knee and no significant change was examined after 9 months postoperatively.

Zizyphus jujube leaf fractions (ZLFs) showed no cytotoxic effects of up to $100{\mu}g/mL$, while the anti-inflammatory effects of ZLFs were analyzed by checking the productions of nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), cyclooxygenase-2 (COX-2), and inflammatory cytokines TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 in the lipopolysaccharide (LPS)-stimulated Raw264.7 macrophage up to the concentration of $100{\mu}g/mL$. ZLFs ($100{\mu}g/mL$) demonstrated a strong anti-inflammatory activity that reduced 61~85% of NO and 71~100% of $PGE_2$ production in the LPS-stimulated Raw264.7 macrophage. Even the low ZLFs concentration of $1{\mu}g/mL$ have reduced NO and $PGE_2$ production by 34~64%. Expressions of COX-2 protein were also effectively inhibited by the ZLFs. Furthermore, the TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 production were significantly suppressed through the treatment of ZLFs at concentrations of 1, 10, and $100{\mu}g/mL$. In the order of the Zizyphus jujube leaf water fraction (ZLWF) < buthanol fraction (ZLBF) < ethyl acetate fraction (ZLEF) showed anti-inflammatory activity. In particular, the ethyl acetate fraction ZLEF at $100{\mu}g/mL$ showed an excellent anti-inflammatory activity by reducing the production of NO, $PGE_2$, COX-2, and inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, IL-6) in the level of Raw264.7 macrophage without LPS-stimulation or even better. The results of our study suggest the potential of ZLEF for use as an excellent ant-inflammatory inhibiting mediator and may be used as a therapeutic approach to various inflammatory diseases.

Background: In an effort to find alternative therapeutic agents to prevent excessive fibrosis as a sequela to complicated parapneumonic effusion or empyema, we examined the effect of tissue plasminogen activator (tPA) as a fibrinolytic agent combined with talc or transforming growth factor (TGF)-${\beta}1$ in a human pleural mesothelial cell line, MeT-5A. Methods: MeT-5A cells were stimulated with various doses of talc, doxycycline or TGF-${\beta}1$ for 24 h and then were treated with tPA for an additional 24 h. Cell viability was measured by MTT assay. The production of interleukin (IL)-8 and vascular endothelial growth factor (VEGF) in the culture supernatants was measured by ELISA. Real-time PCR was carried out for measurement of type I collagen mRNA. Results: MeT-5A cells treated with talc showed a dose-dependent increase in production of IL-8. Talc also increased production of type I collagen mRNA at low doses, but talc did not influence the induction of VEGF. Addition of tPA to talc-stimulated cells showed further increases in the production of IL-8, but tPA did not influence the production of VEGF or type I collagen mRNA. TGF-${\beta}1$ increased the production of both VEGF and collagen type I mRNA, both of which were effectively inhibited by additional tPA treatment in MeT-5A cells. Conclusion: TGF-${\beta}1$ is a potent inducer of collagen synthesis without induction of IL-8 in MeT-5A cells. Addition of tPA after TGF-${\beta}1$ stimulation inhibited further fibrosis by direct inhibition of collagen mRNA synthesis as well as by inhibition of VEGF production.

Objectives : Allergic disease has been well known as an IgE-dependent immunologic response. Recently, interest about the late inflammatory reaction has grown up as well as early allergic reaction characterized by IgE and mast cell. The purpose of this study was to find the anti-inflammatory effect of Gamiyunjo-tang(GMYJT) in allergic reaction. Methods : The experiment was performed using Raw 264.7 cells pretreated with GMYJT extracts. In this study, we observed the toxicity of cells by MTT analysis and measured the production of LPS-induced NO, $PGE_2$, IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ at a concentration of 50, 100, 200 and $400{\mu}g/ml$. Results : No toxicity of GMYJT (50, 100, 200, $400{\mu}g/ml$) on RAW 264.7 cells was found after 24 hours incubation. LPS-induced NO production was reduced after treatment with GMYJT (100, 200, $400{\mu}g/ml$)(P<0.05). $PGE_2$ was reduced after treatment with GMYJT (100, 200, $400{\mu}g/ml$)(P<0.05). IL-$1{\beta}$ did not decrease at any dose. IL-6 decreased at 200, $400{\mu}g/ml$(P<0.05). TNF-${\alpha}$ production decreased only at $400{\mu}g/ml$(P<0.05). Conclusions : These data suggest that GMYJT has anti-inflammatory effects in late allergic reaction.

Objectives: The purpose of this study was to investigate the effects of Angelicae pubescentis Radix water extract (ACE) on immune properties in macrophage cells. Methods: The cells were divided into two groups: As a control, the first was not treated with ACE, and the other was treated with ACE. Together with the cell viability, productions of nitric oxide (NO) and cytokines such as interleukin (IL)-$1{\beta}$, IL-6, and tumor necrosis factor (TNF)-${\alpha}$ by treating of ACE were monitored. Results: 1. There was no decrease of the cell viability after 24 hr incubation, but a significant decrease after 48 hr incubation with all four concentrations (25, 100, 200, and $400\;{\mu}g/m{\ell}$) of ACE. 2. A significant increase in the production of NO was observed in the concentrations above $50\;{\mu}g/m{\ell}$ of ACE after 24 hr incubation. 3. Further, after 48 hr incubation, the critical concentration of ACE for the increase was reduced to $25\;{\mu}g/m{\ell}$. 4. The production of (IL)-$1{\beta}$ significantly increased with the ACE concentrations of 100 and $200\;{\mu}g/m{\ell}$ after 24 hr incubation. 5. The production of IL-6 significantly increased with the ACE concentration of $200\;{\mu}g/m{\ell}$ after 24 hr incubation. 6. A significant increase in the production of (TNF)-${\alpha}$ was detected with ACE concentrations of 50, 100, and $200\;{\mu}g/m{\ell}$ after 24 hr incubation. Conclusions: These show that ACE increases mouse macrophage NO production at concentrations above $50\;{\mu}g/m{\ell}$, and the cytokines ((IL)-$1{\beta}$, IL-6, and (TNF)-${\alpha}$) at concentrations above $200\;{\mu}g/m{\ell}$. These results suggest that ACE improves macrophage immune property.

Background: Cordyceps militaris have been reported to modify the immune and inflammatory responses both in vivo and in vitro. Macrophages play important roles in the innate immunity through the phagocytosis of antigens. This study examined the effects of Cordyceps militaris on the activation of murine macrophage RAW 264.7 cells and primary macrophages. Methods: The components contained in culture broth of Cordyceps militaris were purified by propyl alcohol extraction and HP 20 column chromatography to CMDB, CMDBW, CMDB5P, and CMDB25P. The amounts of nitric oxide (NO) were determined by using ELISA, Griess reagent respectively. The amounts of some cytokines were determined by using ELISA, western blot, and RT-PCR The expression levels of cell surface molecules (ICAM-1, B7-1 and B7-2) were measured by flow cytometric analysis. Results: All the components of Cordyceps militaris produced significant amounts of NO. In particular, CMDB produced much more NO in RAW 264.7 cells and primary macrophages than other fractions of Cordyceps militaris. CMDB increased significantly the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-1${\beta}$, and IL-6 dose-dependently in RAW 264.7 cells. Examination of the gene expression level also showed that the enhanced production of cytokines was correlated with the up-regulation of i-NOS expression, cycloxygenase (COX)-2 expression, IL-1${\beta}$ and IL-6 expression, and TNF-${\alpha}$ expression on the expression of mRNAs by semi-quantitative RT-PCR Western blot analysis also confirmed that CMDB enhances the expression level of these cytokines. Conclusion: These results show that CMDB stimulates the production of NO and pro-inflammatory cytokines and can also up-regulate the gene expression levels in macrophages.

Chamomile (Matricaria chamomilla), a member of the Asteraceae family, is a well-known for medicinal plant and can be found in India and Europe. Chamomile is an effective sedative and various medical effects. But, the effects of acne treatment by chamomile were not investigated. Therefore, we assessed the anti-oxidant effects, anti-microbial activity and anti-inflammatory effects by chamomile extracts in HaCaT keratinocyte cells. Anti-oxidant effects of chamomile extracts were investigated by DPPH assay. Also, results of MTT assay was demonstrated that chamomile extracts did not have a cytotoxic effect in HaCaT cells. To assess the antimicrobial activity, we determined formation of inhibition zone of Propionibacterium acnes by extracts from chamomile. Tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) induces production of inflammatory cytokines such as interleukin-$1{\beta}$ (IL-$1{\beta}$), IL-6 and IL-8 and expression of COX-2. Chamomile extracts could inhibit TNF-${\alpha}$-induced mRNA expression levels of IL-$1{\beta}$, IL-6, IL-8 and COX-2 gene. These results demonstrated the possibility of chamomile for prevention and treatment of skin inflammatory diseases such as acne.
