  • The fermentation of Panax ginseng yields many compounds including ginsenosides that have various biological functions. The objective of this study was to investigate the modulation of nitric oxide (NO), Interleukin (IL)-6 and tumor necrosis factor $(TNF)-{\alpha}$ in Raw 264.7 cells treated with ginseng fermented by Penibacillus MBT213. Nitric oxide production in the Raw 264.7 cells treated for 24 hours with fermented ginseng at 3, 7, and 14 days after the treatment decreased to 74, 43, and 36%, respectively, compared with the positive control. The production of IL-6 was inhibited in all the cells treated with fermented ginseng at 3, 7, and 14 days after the treatment except for the positive control. The $TNF-{\alpha}$ production in the Raw 264.7 cells treated with fermented ginseng for 6 hours at 3, 7, and 14 days after the treatment was about 40,000, 85,000 and 65,000 pg/mL, respectively. Moreover, the $TNF-{\alpha}$ production in the Raw 264.7 cells treated with fermented ginseng for 24 hours at 7 and 14 days after the treatment was about 160,000 and 180,000 pg/mL, respectively. However, $TNF-{\alpha}$ production was inhibited in the Raw 264.7 cells at 6 and 12 hours after the treatment with fermented ginseng. herefore, it was confirmed that the immunological activity of the Raw 264.7 macrophages was affected by the treatment with fermented ginseng. It was concluded that ginseng fermented by Paenibacillus MBT213 possesses a potential anti-inflammatory activity and could be used as an ingredient in functional foods and pharmaceutical products.

  • Background: The immediate hoot response to LPS is the production of proinflammatory cytokines that act as intercellular mediators in inflammatory reactions, including acute lung injury. These "early response" cytokines transmit signals from recognition cells to target or effector cells. This host response is further amplified by the expression of leukocyte chemoattractants, growth factors, and adhesion molecules, resulting in an array of proinflammatory events. This experiment was performed to define the lung origin of proinflammatory cytokines, such as TNF-$\alpha$, IL 6 in early periods of endotoxin induced acute lung injury (ALI). Method: The healthy male Sprague-Dawley, weighted 150 - 250g, were divided into saline control (NC) and endotoxemia-induced ALI (ETX-), and leukopenic endotoxemia-induced ALI (CPA-ETX-Group) which was induced by cyclophosphamide, 70 mg/kg i.p. injection. Acute lung injury was evoked by LPS, 5 mg/kg, intravenously administered. Bronchoalveolar lavage was performed at 0, 3, 6 h after LPS-treated to estimate the influx of phagocytes and concentration of total protein, and cytokines as TNF-$\alpha$ and IL 6 by a bioassy using MIT method. We also examined the localization of TNF-$\alpha$ and IL 6 protein in endotoxemia-challenged lung tissue by immunohistochemical stain (IH). Results: The total cell, macrophage and PMN count in BALF were elavated in ETX group compared to NC(p<0.05). In CPA-ETX group, total cell and macrophage count in BALF were not changed compared to NC. but PMN count was markedly reduced and it took part in less than 0.1 % of total BAL cells (p<0.01). The protein concentration in BALF were significantly increased in ETX and CPA-ETX group Compared to NC (p<0.05), but there was significant difference between ETX- and CPA-ETX group only at 6 h (p<0.05). This observation suggested that even if PMNs are involved in the pathogenesis of acute lung injury, their role cannot be viewed as essential The concentration of TNF-$\alpha$ and IL 6 in BALF was significantly increased in the ETX- and CPA-ETX group compared to NC. There was no difference between ETX- and CPA-ETX group. In IH, anti-TNF-$\alpha$- and anti-IL 6 antibody was strongly localized at interstitial monocytes and alveolar macrophages in endotoxemia-challenged lung tissue. From above point of view, activated alveolar macrophage/monocyte considered as a prominent source of proinflammatory cytokines in endotoxemia-challenged lung injury. Conclusion: The prominent source of proinflammatory cytokines in early periods of endotoxemia-induced lung injury will be the activated resident macrophages like an alveolar macrophage and interstitial monocytes. The pulmonary macrophage/monocyte will impact the initiation and continuance of lung injury without PMNs's certain inflammatory role, particularly in endotoxemia-induced acute lung injury.

  • Obesity is consistently increasing in prevalence and can trigger insulin resistance and type 2 diabetes. Many lines of evidence have shown that macrophages play a major role in inflammation associated with obesity. This study was conducted to determine metformin, a widely prescribed drug for type 2 diabetes, would regulate inflammation through down-regulation of scavenger receptors in macrophages from obesity-induced type 2 diabetes. RAW 264.7 cells and peritoneal macrophages were stimulated with LPS to induce inflammation, and C57BL/6N mice were fed a high-fat diet to generate obesity-induced type 2 diabetes mice. Metformin reduced the production of NO, $PGE_2$ and pro-inflammatory cytokines ($IL-1{\beta}$, IL-6 and $TNF-{\alpha}$) through down-regulation of $NF-{\kappa}B$ translocation in macrophages in a dose-dependent manner. On the other hand, the protein expressions of anti-inflammatory cytokines, IL-4 and IL-10, were enhanced or maintained by metformin. Also, metformin suppressed secretion of $TNF-{\alpha}$ and reduced the protein and mRNA expression of $TNF-{\alpha}$ in obese mice as well as in macrophages. The expression of scavenger receptors, CD36 and SR-A, were attenuated by metformin in macrophages and obese mice. These results suggest that metformin may attenuate inflammatory responses by suppressing the production of $TNF-{\alpha}$ and the expressions of scavenger receptors.

  • 본 연구는 표고버섯에서 분리정제한 렉틴 성분(LEL)을 말초혈액 단핵세포(PBMC)에 반응시켜 사이토카인 유도능을 지질다당류(LPS)와 비교하여 역전사효소 중합반응법(RT-PCR)으로 측정하였다. 측정 대상 사이토카인은 IL-1, IL-2, IL-6, TNF$\alpha$ 및 IFN${\gamma}$의 다섯가지였으며 이들을 대상으로 PBMC에 렉틴을 적용하여 1, 8, 24, 48, 72, 96, 120분 등의 시간대에서 반응시켜 사이토카인의 유전자 발현 유도에 관한 다음의 결과를 얻었다. LEL의 사용 농도에 따른 편도선 림프구(tonsillar lymphocyte)의 TNF$\alpha$ 유전자 발현 양상은 반응 1시간의 경우 LEL의 일부 농도와 LPS 전농도에서 관찰되었으나 반응 40시간째에는 LEL 전농도와 LPS 전농도에서 TNF$\alpha$ 유전자 발현 양상을 관찰할 수 없었다. RT-PCR 결과 원액이나 회석액 재료로부터 관찰된 TNF$\alpha$유전자 band의 강 약 차이는 나타나지 않았다. LEL의 자극에 의한 반응 시간대 별 PBMC에 의한 사이토카인 유전자 발현 양상은 위에서 언급된 다섯가지 사이토카인을 유도, 생성할 수 있다는 것이 확인되었는데, IL-2, IL-6 및 IFN${\gamma}$는 120시간까지 장시간 지속되는 유전자 발현이 가능한 반면 TNF $\alpha$의 생성 양상은 이들 사이토카인의 생성 양상과는 판이하게 반응 1, 8 및 24 시간대까지만 TNF$\alpha$ 유전자 발현을 관찰할 수 있었고 IL-1은 72 시간까지 반응을 나타내는 등 특이적 양상을 보였다. 한편 LPS는 실험에 사용된 전 사이토카인의 유전자 발현을 120시간대까지 반응이 유지됨을 관찰하였기에 LPS가 PBMC의 강력한 사이토카인 유도체임을 입증할 수 있었으며 LEL과 다소 상이한 결과를 보였으나 LEL 또한 PBMC로부터 사이토카인을 생성 유지시킬 수 있는 유도체로 작용함을 확인할 수 있었다.

  • Acute septic shock is one of inflammatory diseases mediated by pro-inflammatory cytokines such as tumor necrosis factor (TNF)-${\alpha}$. In this study, we examined the pathological difference and mechanism of lipopolysaccharides isolated from E. coli (E-LPS) or S. abortus (S-LPS) on inducing acute septic shock in ICR mouse. All mice were died by intraperitoneal treatment of S-LPS with 0.75 mg/kg, whereas E-LPS treated with even 3 mg/kg only showed 30% of mice lethal, indicating that S-LPS may be more feasible in triggering a strong septic shock condition. The secretion pattern of TNF-${\alpha}$, a critical pro-inflammatory cytokine in septic shock condition, was also distinct between E-LPS- and S-LPS-treated groups. Thus, S-LPS strikingly increased serum level of TNF-${\alpha}$ (6 ng/ml) at 1 h, while E-LPS just displayed at 2 ng/ml level. However the interaction of S-LPS with LPS receptor toll like receptor (TLR)-4, was not stronger than that of E-LPS, according to experiments with macrophage cell line RAW264.7 cells. Thus, E-LPS rather than S-LPS strongly enhanced the production of TNF-${\alpha}$. Interestingly, S-LPS more strongly up-regulated splenocyte proliferation, compared to E-LPS group, whereas there was no difference between S- or E-LPS treated groups in proliferation of Balb/c- or C57BL/6-originated splenic lymphocytes. Therefore, our data suggest that S-LPS is a more active endotoxin and that the strong septic shock-inducing effect of S-LPS seems due to the enhancement of early TNF-${\alpha}$ production and S-LPS-sensitive lymphocyte proliferation.

  • Objectives : This study was conducted to investigate the effects of Gwakhyangjeonggi-san(GJS) on atopic dermatitis(AD) induced by 2,4-dinitrochlorobenzene(DNCB) in mice. Methods : The mice(Balb/c mice) were divided into three groups; normal Balb/c mice with oil treatment(Sham group), DNCB-induced AD mice(AD group), and GJS treated AD mice(GJS group). GJS group were orally administered GJS daily for 2 weeks. We observed changes of clinical skin severity score, the expression of thymic stromal lymphopoietin(TSLP), interleukin(IL)-4 and tumor necrosis factor(TNF)-${\alpha}$ in skin and mast cell infiltration. Also, serum immunoglobulinE(IgE), IL-4, $TNF-{\alpha}$ and IL-6 were evaluated. Results : The clinical skin severity score of GJS group was decreased compared to AD group. In hematoxylin and eosin staining results, GJS group showed a significant reduction of epithelial skin thickness. In addition, expression of TSLP and mast cell infiltration in skin were also reduced by GJS treatment compared to those of AD group. Thus, we evaluated expression of IL-4, Th2-dependent cytokine, and $TNF-{\alpha}$, pro-inflammatory cytokine in skin. GJS significantly reduced both IL-4 and $TNF-{\alpha}$ compared to AD mice. Moreover, levels of IgE, IL-4, $TNF-{\alpha}$ and IL-6 in plasma also significantly decreased by oral GJS treatment. Conclusion : The present study suggests that GJS can significantly reduced symptoms of AD, therefore it can be a promising candidate for anti-atopic dermatitis treatment.

  • The Wnt/$\beta$-catenin signaling pathway alters adipocyte differentiation by inhibiting adipogenic gene expression. $\beta$-catenin plays a central role in the Wnt/$\beta$-catenin signaling pathway. In this study, we revealed that tumour necrosis factor-$\alpha$ (TNF-$\alpha$), a potential negative regulator of adipocyte differentiation, inhibits porcine adipogenesis through activation of the Wnt/$\beta$-catenin signaling pathway. Under the optimal concentration of TNF-$\alpha$, the intracellular $\beta$-catenin protein was stabilized. Thus, the intracellular lipid accumulation of porcine preadipocyte was suppressed and the expression of important adipocyte marker genes, including peroxisome proliferator-activated receptor-$\gamma$ (PPAR$\gamma$) and CCAAT/enhancer binding protein-$\alpha$ (C/EBP$\alpha$), were inhibited. However, a loss of $\beta$-catenin in porcine preadipocytes enhanced the adipogenic differentiation and attenuated TNF-$\alpha$ induced anti-adipogenesis. Taken together, this study indicated that TNF-$\alpha$ inhibits adipogenesis through stabilization of $\beta$-catenin protein in porcine preadipocytes.

  • Purpose: The aims of this study were to analyze the association between inflammatory cytokine and obstructive sleep apnea (OSA), and to evaluate treatment outcome and changes of plasma inflammatory cytokine levels after oral appliance therapy. Methods: Twenty-seven subjects who visited Department of Oral Medicine in Seoul National University Dental Hospital were performed nocturnal polysomnography and analyzed plasma C-reactive protein (CRP), interleukin (IL)-$1{\beta}$, IL-6, IL-10, and tumor necrosis factor (TNF)-${\alpha}$ levels. Each subject was evaluated with Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). The subjects were classified into 12 OSA patients (apnea-hypopnea index [AHI] >5) and 15 control (AHI ${\leq}5$) groups. The OSA group was treated with mandibular advancement device (MAD) for 3 months and re-evaluated nocturnal polysomnography and plasma inflammatory cytokine levels. Results: Plasma TNF-${\alpha}$, IL-10, and IL-6 levels were significantly higher in OSA patients compared to controls. Total AHI showed significant positive correlations with plasma IL-6 and TNF-${\alpha}$ levels. Percentage time of $SpO_2$ <90 and lowest $SpO_2$ were significantly correlated with plasma TNF-${\alpha}$ level. ESS showed significant positive correlation with plasma IL-10 level. Total AHI, percentage time of $SpO_2$ <90, lowest $SpO_2$, and mean $SpO_2$ were significantly improved after the MAD therapy. Plasma TNF-${\alpha}$ level was significantly decreased after MAD therapy. Conclusions: We suggest that MAD therapy is an effective treatment modality for patients with OSA and can decrease plasma cytokine level.

  • Objective : This study was conducted to investigate the effects of Hwangryunhaedok-Tang and Geongangbuja-Tang on the change of interleukin-6 (IL-6) and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) level induced by LPS I.C.V. injection in mice. Method : We devided group into 6 mice and 6 mice were assingned to each group. In the normal group only saline was administered intragastrically, and in the control group LPS was injected intracerebroventricularly 1 hr after intragastric administration of saline. In the experiment groups Hwangryunhaedok-Tang(0.5g/kg, 1.0g/kg, 3.0g/kg) was administered intragastrically to mice 1 hr prior to LPS(100mg/mouse) I.C.V. injection.. Also Geongangbuja-Tang (0.5g/kg, 1.0g/kg, 3.0g/kg) was administered intragastrically to mice 1 hr prior to LPS(100mg/mouse) I.C.V. injection. To measure the plasma IL-6 and $TNF-{\alpha}$ level of mice, their blood samples were collected from retro-orbital plexus, immediately centrifuged at $4^{\circ}C$, and plasma was removed and stored frozen at $-83^{\circ}C$ for later determination of IL-6 and $TNF-{\alpha}$. The level of IL-6 and $TNF-{\alpha}$ production was measured by enzyme-linked immunosorbent assay in the plasma. Result : Regarding IL-6 level, The 0.5g/kg and the 1g/kg groups of Geongangbuja-Tang decreased IL-6 level. Especially the 3g/kg control group decreased IL-6 level significantly than the normal group(p<0.01). Regarding $TNF-{\alpha}$ level, the 3g/kg group of Geongangbuja-Tang decreased it significantly(p<0.05). Conclusion : These data revealed that Hwangryunhaedok-Tang might not have the anti imflammatory effect and Geongangbuja-Tang(3g/kg)might have the anti imflammatory effect by reducing the plasma IL-6 and $TNF-{\alpha}$ level in mice LPS Injection.EIM (Eighteen Incompatible Medicaments) is an important component in Oriental pharmacology and is directly related to clinical prescriptions. Medical practitioners argued that the definite cause and meaning of EIM was ambiguous and therefore debated the issue of clinical application of the EIM. This study conducted an in-depth literary research on the origin, meaning and contents of EIM with the purpose to contribute in its efforts to be used clinically. Even after thousands of years have past since establishment of Oriental medicine, EIM is still tabooed and was an obstacle that hindered ideologies. Modern herbal medicine texts claim that the use of EIM can reduce treatment effects and promote poisoning and side effects. However, since long ago, there has been medical practitioners who reject this as false. Recently, poisoning caused by EIM has been claimed to be from the toxicity of the drug itself, rather than the result of interaction between the drugs, and therefore they suggest that EIM is not a forbidden domain. In addition, EIM showed a difference in number depending on the era. However, this can be understood not as a definite number, but instead as a warning to be careful during combination of drugs for use as clinical medicine. Historically, there were very few cases in which EIM was used for clinical tests and thus, the clinical value is not, while others applied EIM directly to their bodies, which showed signs for the usefulness and potential of EIM for us. A more concrete and in-depth study must be made on EIM.
