  • Objective : This experiment was performed in order to study the effect of an aqueous extract of Salviae radix root(SRRAE) on NO production and NOS gene induction from macrophages Methods : To investigate dose-dependent effects of SRRAE for NO release on the $rIFN-{\gamma}-treated$ macrophages, the cells were incubated for 6 hrs in a medium containing $rIFN-{\gamma}$ (5 U/ml), stimulated with SRRAE and incubated in a CO2 incubator. The cells were treated with 5 U/ml $rIFN-{\gamma}$ plus 100 g/ml of SRRAE, Then, the cells were incubated with various concentrations of NGMMA at $37^{\circ}C$ for 48 hrs, Results : SRRAE had no effect on NO production by itself, whereas recombinant $interferon-{\gamma}(rIFN-{\gamma})$ alone showed modest activity, When SRRAE was used in combination with $rIFN-{\gamma}$, there was a marked cooperative induction of NO production in a dose-dependent manner. The optimal effect of SRRAE on NO production was shown at 6hrs after treatment with $rIFN-{\gamma}$. The SRRAE-induced production of NO was inhibited by NG-monomethyl- L-arginine(NGMMA) and arginase. $rIFN-{\gamma}$ in combination with SRRAE showed a marked increase of the expression of the inducible NOS(iNOS) gene. In addition, the effect of SRRAE was mainly dependent on the SRRAE-induced tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ secretion. Conclusions : SRRAE induces NO production from macrophages as a result of SRRAE-induced $TNF-{\alpha}$ secretion. SRRAE may provide a second signal for synergistic induction of NO production in macrophages already induced to express iNOS gene by $rIFN-{\gamma}$.

  • 목 적 : ${\alpha}$-Galactosylceramide (GalCer)로 자극한 자연살상 T 세포(NKT)는 CD1d 및 T 세포 수용체(T cell receptor) 의존적으로 일부 백혈병에서 항암효과를 발현하나, CD1d음성인 신경모세포종에서는 세포독성을 유도할 수 없다. 이들 NKT세포의 활성화 시 분비되는 많은 양의 사이토카인의 직접적인 항암효과에 대해서는 소수의 보고가 있다. 본 연구에서는 hCD1d/${\alpha}$-GalCer tetramer로 NKT세포를 자극하여 얻은 상청액(supernatant)을 이용하여 NKT세포에 의한 신경모세포종의 치료적 접근의 가능성을 알아보았다. 방 법 : 신경모세포종 세포 주를 IMDM 배지에 배양하였고, NKT세포에서 분비되는 사이토카인 양은 cytometric bead array (CBA)분석으로 측정하였다. 세포 생존율은 calcein-AM 형광물질을 이용하여 digital image microscopy scanning (DIMSCAN)으로 측정하였고 특이 세포고사(specific apoptosis)는 annexin V and 7-AAD 염색 후 유식세포분석기를 통하여 산출하였다. 결 과 : 활성화된 NKT세포는 많은 양의 IL-2, IL-4, INF-${\gamma}$와 TNF-${\alpha}$을 분비하였다. NKT 자극 후 얻어진 상청액은 8개의 신경모세포종 세포 주 중 4개에서 의미있는 세포독성을 나타냈으며, 그 기전은 annexin-V 염색이나 pancaspase 억제제의 전 처치 실험으로 세포고사을 통하여 유도됨을 알 수 있었다. 그리고 이들 세포고사 유도는 anti-TNF-${\alpha}$, anti-IFN-${\gamma}$ 중화항체의 단독투여 시 현저히 감소하였고 동시투여 시에는 완전하게 억제되었다. 결 론 : NKT 세포의 활성화에 의해 분비된 IFN-${\gamma}$와 TNF${\alpha}$가 일부 신경모세포종 세포 주에서 협동적 세포 독성을 유도하였다.

  • Objectives GyejigaChulBuTang (GCBT) is a prescription used to treat acute and chronic arthritis in Korea, China, and Japan. This study assessed the anti-inflammatory and anti-oxidant activities of GCBT on lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. Methods Raw264.7 cells were pretreated with or without GCBT for 1 hour prior to incubation with LPS. Anti-inflammatory activity of GCBT was evaluated with reference to gene expression and production levels of proinflammatory cytokines ($TNF{\alpha}$, IL-$1{\beta}$, IL-6, GM-CSF and $INF{\gamma}$) and inflammatory mediators (iNOS, COX-2, NO and $PGE_2$). In addition, intracellular ROS generation and signal transduction of MAPK family, PI3K/Akt and $I{\kappa}B{\alpha}/NF{\kappa}B$ was investigated. Results Prior treatment with GCBT inhibited elevation of $TNF{\alpha}$, IL-$1{\beta}$, IL-6, GM-CSF, $INF{\gamma}$, NO and $PGE_2$, together with their cognate mRNAs in a dose-dependent manner. Intracellular ROS contents were similarly reduced. These effects were due to inhibition of LPS-induced phosphorylation of MAPK family, PI3K/Akt and $I{\kappa}B{\alpha}$ as well as nuclear translocation of $NF{\kappa}B$. Conclusions GCBT suppresses pro-inflammatory mediators. GCBT has potential in the treatment of juvenile rheumatoid arthritis associated with inflammation.

  • Soyangin-Hyeongbangpaedok-san(SHBPDS) is used for treating upper respiratory infections, In an effort to investigate the anti-inflammatory effects of SHBPDS, we measured production of several cytokines and immunoglobulin in various immune cells. SHBPDS decreased the secretion of TNF-${\alpha}$, but not that of IL-6 in PMA/A23187 stimulated HMC-1 cells. As for mouse B cells, it induced proliferation and caused differential effects in expressions of surface IgE as determined by flow cytometry and secretions of IgE, IgG1, ILA and INF-${\gamma}$as measured by ELISA but showed little change in CD23 or CD69 expression. SHBPDS increased proliferation in anti-CD3/anti-CD28 stimulated CD4 Th cells. Under the Th1/Th2 polarization conditions, SHBPDS at 200 ${\mu}g/m{\ell}$ suppressed the secretion of INF-${\gamma}$ and IL-4. Based on the above results, we conclude that SHBPDS has antiinflammatory activities in mast cells and different immunomodulatroy effects in B cells and Th cells.

  • Prokaryotic and eukaryotic cells respond to heat stress and other environmental abuses by synthesizing a small set of stress proteins and by inhibiting post-transcription synthesis of normal proteins. The purpose of the present study was to document the stress response produced by inflamed gingival tissue in vivo, and cytokine inducted human periodontal ligament cells. Human PDL cells were exposed to TNF-$\alpha$(1ng/ml), INF-$\gamma$(200 U/ml), LPS(100ug/ml), combination of cytokine, and SDS-PAGE gels running and Western blotting analysis was done. In vivo studies, the healthy gingival tissusse of a control group and inflamed gingival tissue of adult periodontitis were studied by immunohistochemistry and histology. The results were as follows 1. HSP 47 was distributed on basal layer in healthy gingiva, but stronger stained in basal, suprabasal, and spinous layer of inflamed gingiva. 2. HSP 47 was rare on endothelial cells and mononuclear cells in healthy gingiva, but stronger expressed in inflamed gingiva. 3. HSP 70 expression was rare on epihelium and inflammatory cells hi both healthy & inflamed gingiva. 4. HSP 70 was actively expressed on endothelial cells and inflammatory cells of capillary lumen in moderately & mild inflamend gingiva. 5. PDL cells showed low level of HSP 47 protein expression which was significantly induced by cytokine stimulation (LSP only and combination). 6. Maximum HSP 70 protein induction was seen with stimulation by a combination of the cytokine, Combination of TNF-$\alpha$, INF-$\gamma$, LPS have been shown to synergistically effects of HSP 70 expression. On the above findings, HSP Is influenced by cytokine and chronic inflammation in vivo, and may be involved in protection of tissue during periodontal inflammatiom.

  • 인삼과 팽화홍삼은 인삼의 가공방법에 따라 구분되어지며, 가공처리과정중 인삼의 효능을 나타내는 사포닌 함량의 변화가 생긴다. 본 연구에서는 인삼과 팽화홍삼을 이용하여 마우스 대식세포인 RAW 264.7세포에서 LPS에 의한 염증에 대한 항염 효과와 그 기전을 규명하고자 하였다. 본 연구를 통해서 인삼과 팽화홍삼 모두 LPS에 의한 NO의 생성을 억제시키는 것을 확인하였으며, TNF-$\alpha$ 및 INF-$\gamma$의 생성 또한 억제시키는 것을 알 수 있었다. 인삼과 팽화홍삼 모두 COX-2의 발현 및 LPS에 의한 $I{\kappa}B$의 인산화를 억제시킴으로써 NF-${\kappa}B$의 활성을 억제시키는 것임을 알 수 있었으나 인삼에 비하여 팽화홍삼의 항염 효과가 더욱 높았다. 그러므로 팽화홍삼이 인삼에 비하여 NO의 생성을 더 효과적으로 억제시키는 것은 팽화가공을 통하여 특정 진세노사이드($Rb_1,\;Rg_5+Rk_1$)의 증가에 의한 것으로 추정된다.

  • Moxibustion is one of major healing technique in oriental medicine. It has been widely used in many diseases such as rheumatoid arthritis, Hashimoto disease, breech presentation, etc. However, till now, effects of moxibustion on NK cell activity and relations between sympathetic nerve system(SNS) and the immune alteration induced by moxibustion were not well studied. This study was designed to evaluate effects of moxibustion on NK cell activity and the intervention of SNS in the alteration of NK cell activity induced by moxibustion. Splenic NK cytotoxity was measured in a standard 4-h 51Cr release assay. We measured the NK cytotoxity at after moxibustion stimulation for 1,3,5, and 7 days, and also measured the NK cell cytotoxity after 3 and 7 days burn stimulation with similar temperature. IL-2, IL-4, INF-γ in serum were measured by rat IL-2, IL-4, INF-γ ELISA TEST KIT. To evaluate the effects of sympathectomy on alteration of NK cell cytotoxity, 6-hydroxydopamine(6-OHDA : 5Omg/kg) was used. We showed that NK cell activity of moxibustion stimulation group increased at the 3rd day, and declined at 7th day in comparison with that of contol group. In moxibustion stimulation group, NK cell activity of 3 day stimulation group was significantly higher than sham group. On the contrary, in burn stimulation group, NK cell activity was significantly higher than that of sham groups at 3rd, 7th days. Patterns between moxibustion and burns were different. INF- γ level of 3 days moxibustion stimulation group significantly higher than sham group. IL 2 level among groups were not different. IL-4 was not detected in serum with this method. Sympathectomy abolished the NK cell activity alteration induced by moxibustion. The results suggest that moxibustion induces the alteration of NK cell activity, along with INF-γ and SNS is related to these effects.
