  • Yeonguemjiri-tang(連芩止痢湯, YGT) exhibits potent anti-inflammatory activity in widely intestine disease, but its mechanism undisclosed. To elucidate the molecular mechanisms of YGT on pharmacological and biochemical actions in inflammation, we examined the effect of YGT on pro-inflammatory mediators in phorbol 12-myristate 13-acetate (PMA) plus A23187-induced mast cell and lipopolysaccharide (LPS)-stimulated macrophages. The investigation focused on whether YGT inhibited pro-inflammatory cytokines such as interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in PMA plus A23187-induced HMC-1 cells and inflammatory madiators such as nitric oxide (NO), TNF-${\alpha}$, IL-6, iNOS, COX-2 in LPS-stimulated RAW 264.7 cells. We found that YGT inhibited LPS-induced NO, TNF-${\alpha}$ and IL-6 productions as well as the expressions of iNOS and COX-2. These results suggest that YGT has inhibitory effects on mast cell-mediated and macrophage-mediated inflammation.

  • Objectives : We studied anti-allergic effects of Cinnamomi Ramulus(CR) herbal acupuncture and Cinnamomi Ramulus extract. Methods : In vivo, animals were herbal-acupunctured with CR at both ST36s three times for 5 days. Then, we induced active systemic anaphylatic shock using compound 48/80 in ICR mice, and passive cutaneous anaphylaxis using anti-DNP IgE in Sprague Dawley rat. In vitro, we measured cell viability, ${\beta}$ -hexosaminidase release and the expressions of IL-4, TNF-${\alpha}$ and COX-2 mRNA in RBL-2H3 cells after treatment of various concentrations of CR extract. Results : In vivo, CR herbal acupuncture pretreatments at both ST36s inhibited compound 48/80-induced active systemic anaphylatic shock. Passive cutaneous anaphylaxis was inhibited by CR herbal acupuncture pretreatments at both ST36s and optional points. In vitro, CR extract treatments did not affect on cell viability and inhibited ${\beta}$-hexosaminidase release. CR extract treatments also decreased the expressions of IL-4, TNF-${\alpha}$ and COX-2 mRNA in RBL-2H3 cells. Conclusions : These results suggest that CR herbal acupuncture and CR extract should be beneficial in the inhibition of allergic inflammatory response.

  • Objectives: This study was to investigate the anti-oxidative and anti-inflammatory effect of Psoralea corylifolia water extract (PE) on ulcerative colitis which was induced by dextran sulfate sodium (DSS) in mice. Methods: Ulcerative colitis was induced by DSS in male BALB/c mice. The mice were divided into 3 groups. The control group (Ctrl) was not induced ulcerative colitis. The pathological group (CE) was induced the colitis. The experimental group (PT) was administered PE after inducing the colitis. The effects of the PE on ulcerative colitis were evaluated by morphological change in the colon tissue and cells, substance P production, activity of tumor necrosis factor $(TNF)-{\alpha}$ and nuclear factor $(NF)-{\kappa}B$, cyclooxygenase (COX)-2 production, and anti-oxidative activity. Results: In the PT group, PE alleviated hemorrhagic erosion in colon mucosa and infiltration of inflammatory cells in lamina propria mucosae. In the colon of the PT group, COX-2 production was inhibited via regulating the activity of $TNF-{\alpha}$ and $NF-{\kappa}B$ p65. PE also had an anti-oxidative effect via activating nuclear factor (erythroid-derived 2)-like 2 (Nrf2). Conclusions: In this study, we found the utility of treatment with PE and the potential of developing a medicine for ulcerative colitis by applying our results. Further investigations for the anti-inflammatory mechanism of PE may be needed.

  • Objectives : Neuroinflammation is characterized by microglial activation and the expression of major inflammatory mediators. The present study investigated the inhibitory effect of ginsenoside Rg1 ($GRg_1$), a principle active ingredient in Panax ginseng, on pro-inflammatory cytokines and microglial activation induced by systemic lipopolysaccharide (LPS) treatment in the mouse brain tissue. Methods : Varying doses of $GRg_1$ was orally administered (10, 20, and 30 mg/kg) 1 h before the LPS injection (3 mg/kg, intraperitoneally). The mRNA expression of pro-inflammatory cytokines in the brain tissue was measured using the quantitative real-time PCR method at 4 h after the LPS injection, Microglial activation was evaluated using western blotting and immunohistochemistry against ionized calcium binding adaptor molecule 1 (Iba1) in the brain tissue. Cyclooxigenase-2 (COX-2) expressions also observed using western blotting and immunohistochemistry at 4 h after the LPS injection, In addition, double-immunofluorescent labeling of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and COX-2 with microglia and neurons was processed in the brain tissue. Results : $GRg_1$ (30 mg/kg) significantly attenuated the upregulation of TNF-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-6 mRNA in the brain tissue at 4 h after LPS injection. Morphological activation and Iba1 protein expression of microglia induced by systemic LPS injection were reduced by the $GRg_1$ (30 mg/kg) treatment. Upregulation of COX-2 protein expression in the brain tissue was also attenuated by the $GRg_1$ (30 mg/kg) treatment. Conclusion : The results suggest that $GRg_1$ is effective in the early stage of neuroinflammation which causes neurodegenerative diseases.

  • Our study shows that EC extract has inhibitory effect on pro-inflammatory cytokines such as TNF-α, IL-1, IL-6, iNOS and COX2 in hFLSs. IL-1β, IL-6, iNOS and COX2 mRNA expression is suppressed at a low dasage (1㎍/ml) of EC extract. TNF-α was also suppressed at higher dosages (10 ㎍/ml, 100㎍/ml). EC extract also inhibited TNF-α, IL-1β and IL-6 production in pro-inflammatory cytokine stimulated-hFLSs. Expecially IL-1β(p<0.05) production are suppressed significantly. On the other hand, EC extract did not show any cytotoxicity. Thses data suggest that EC extract has anti-inflammatory effect mostly by inhibiting IL-1β production, and thus could be used to prevent or treat some inflammatory disease such as RA. It remains to be known what are the major components responsible for anti-inflammatory effect and what is the main mechanism.

  • 상황버섯 배양균사체 추출물 (MCPL)이 알코올성 간 손상에 미치는 영향을 살펴보았다. Sprague-Dawley계 흰 쥐에 40% 알코올 3 ml을 MCPL (5 mg 및 15 mg/Kg)과 함께 1일 1회 10일간 투여하였다. 간 기능의 표지가 되는 혈청내 AST와 ALT값이 에탄올에 의해 현저히 증가하였으나 MCPL 투여에 의해 저하되며 특히 ALT 값이 유의성 있게 낮아졌다. 병리조직학적으로 살펴보면 알코올에 의해 염증세포의 침윤, 쿠퍼세포 반응 및 국소적 염증이 유발되나 MCPL투여에 의해 그 정도가 다소 완화되었다. 간소엽내 글리코겐 분포도 알코올에 의해 감소하나 MCPL투여에 의해 중심정맥주변 부위의 분포가 일부 회복되었다. 염증관련 단백질에 대한 Western blot 및 면역조직화학적 반응을 보면 에탄올 투여에 의해 COX-2, iNOS 및 $TNF-{\alpha}$ 면역반응이 증가하나 MCPL투여에 의해 발현의 감소를 볼 수 있었다. 이상의 결과로 보아 MCPL은 알코올에 의한 간 손상에 대해 보호 기능을 가짐을 알 수 있다.
