본 연구에서는 참도박 에탄올 추출물(GEHEE)의 항염증 효과를 알아보기 위해 lipopolysaccharide에 의해 활성화된 대식세포로부터 분비되는 염증매개인자들의 발현량과 마우스 모델을 이용한 귀 부종 및 조직학적 관찰 실험을 진행하였다. 그 결과 염증을 유발하는 대표적 물질인 NO 및 사이토카인[interleukin(IL)-6, $IL-1{\beta}$ 및 tumor necrosis factor $receptor-{\alpha}$]의 분비량이 GEHEE 농도 의존적으로 유의적 감소를 보였다. 또한 전사인자인 nuclear $factor-{\kappa}B$의 활성과 인산화효소인 mitogen-activated protein kinases(p38, JNK 및 ERK)의 발현량이 억제됨을 확인함에 따라 염증작용 기전에서 이들의 활성 억제가 NO 및 사이토카인 분비량 조절에 영향을 미침을 확인하였다. 동물모델을 이용한 실험에서는 croton oil로 부종을 유발한 마우스 귀 조직에 GEHEE를 처리하였을 때 항염증제인 prednisolone 처리구와 유사한 수준으로 경피 및 진피의 두께가 감소한 것을 확인하였으며, 조직 내 침윤되는 mast cell의 수도 현저히 억제됨을 확인하였다. 따라서 본 연구 결과는 참도박 에탄올 추출물의 항염증 효능을 가진 기능성 소재로의 이용 가능성을 제시한다.

Previous screening of the pharmacological action of Gastrodia elata (GE) root (Orchidaceae) showed that methanol (MeOH) extracts have significant anti-inflammatory properties. The antiinflammatory agents of GE, however, remain unclear. In this experiment, MeOH extracts of GE were fractionated with organic solvents for the anti-inflammatory activity-guided separation of GE. Eight phenolic compounds from the ether (EtOEt) and ethyl acetate (EtOAc) fractions were isolated by column chromatography: 4-hydroxybenzaldehyde (I), 4-hydroxybenzyl alcohol (II), benzyl alcohol (III), bis-(4-hydroxyphenyl) methane (IV), 4(4'-hydroxybenzyloxy)benzyl-methylether (V), 4-hydroxy-3-methoxybenzyl alcohol (VI), 4-hydroxy-3-methoxybenzaldehyde (VII), and 4-hydroxy-3-methoxybenzoic acid (VIII). To investigate the anti-inflammatory and anti-oxidant activity of these compounds, their effects on carrageenan-induced paw edema, arachidonic acid (AA)-induced ear edema and analgesic activity in acetic acid (HAc)-induced writhing response were carried out in vivo; cyclooxygenase (COX) activity, reactive oxygen species (ROS) generation in rat basophilic leukemia (RBL 2H3) cells and 1,1-diphenyl-2-picryl-hydroazyl (DPPH) scavenging activity were determined in vitro. These phenolic compounds not only had anti-inflammatory and analgesic properties in vivo, but also inhibited COX activity and silica-induced ROS generation in a dose-dependent manner. Among these phenolic compounds, compound VII was the most potent anti-inflammatory and analgesic. Compound VII significantly inhibited silica-induced ROS generation and compound VI significantly increased DPPH radical scavenging activity. Compounds I, II and III significantly inhibited the activity of COX-I and II. These results indicate that phenolic compounds of GE are anti-inflammatory, which may be related to inhibition of COX activity and to anti-oxidant activity. Consideration of the structure-activity relationship of the phenolic derivatives from GE on the anti-inflammatory action revealed that both C-4 hydroxy and C-3 methoxy radicals of benzyl aldehyde play an important role in anti-inflammatory activities.

Rheumatoid arthritis(RA) is a general, chronic, inflammatory and auto-immune disease and it can lead to joint edema, pain, stiffness which are caused by an inflammation in synovium covering our joints. Ulmus davidiana Planchon is a traditional herb used for the treatment on various inflammations, gastrointestinal trouble, ENT(ear, nose, and throat) disease, edema, cancer etc. and it works effectively on arthritis as well. In these study to search for the treatment efficacy of Ulmus davidiana Planchon in RA, I measure manifestation of cytokine gene in synoviocyte treated with Ulmus davidiana Planchon herbal acupuncture and in EL-4 cell, manifestation of cytokine gene cell related to T-cell. And after Ulmus davidiana Planchon herbal acupuncture treatment in Collagen induced arthritis(CIA) which has been known by a general model of RA, DBA mice, I observed foot thickness, general shape of synovium, early cytokine induce CIA and, generation and mutation of cytokine related to the control of T-cell specialization. It comes to conclusion as belows. 1. In synovium treated with Ulmus davidiana Planchon herbal acupuncture, there was the decrease in MIF mRNA does-dependently. Incase of CIA mice treated with Ulmus davidiana Planchon herbal acupuncture, there were the decrease in the damage in synovium and generation of the MIF which is related to induction of the early RA cytokine and IL-6 proinflammatory cytokine. 2. In case of EL-4 treated with Ulmus davidiana Planchon herbal acupuncture, there were decrease in the manifestation of the IL-2 mRNA, but the increase in the manifestation of the IL-4 does-dependently. 3. In the synovium of CIA mice treated with Ulmus davidiana Planchon herbal acupuncture, there were the decrease in generation of IL-2, IL-12 and CD-28, but the increase in generation of IL-4. These result suggest that Ulmus davidiana Planchon can block the process of the early RA by Inhibiting MIF activation, and mitigate Rheumatoid Arthritis by controlling Tcell specialization.

Objectives In this study, we investigated the inhibitory effects of Samhwangsasim-tang (S.H) on the allergic response caused by ovalbumin(OVA) sensitization and challenge in BALB/c mice. Methods The experimental animals were divided into five groups; 1) normal as negative control, 2) OVA-sensitized mice, 3) OVA-sensitized mice treated with 200 mg/kg of S.H 200, 4) OVA-sensitized mice treated with 400 mg/kg of S.H 400, and 5) OVA-sensitized mice treated with 5 mg/kg of Dexamethasone (Dex). Antigen sensitization for allergic mouse model was performed with twice injection of OVA for 2 weeks. After secondary injection, S.H was administrated orally into mice every day for 13 days and the inhibitory effect of S.H on allergic responses was evaluated. Results Treatment of S.H into allergic mice reduced significantly ear edema and infiltration of immune cells in ear tissues induced with OVA challenge in a dose-dependent manner. S.H reduced significantly the serum levels of Total Immunoglobulin(Ig)G and IgE, and particularly inhibited the production of OVA-specific IgE, but not OVA-specific IgG. The serum level of proinflammatory cytokine TNF-${\alpha}$ and Th2-associated cytokine IL-4 also were significantly decreased by S.H adminstration in a dose denpendent manner. S.H attenuated OVA-induced secretion of IFN-${\gamma}$, but not IL-12 which is a cytokine inducing the development of Th1 cells. It also reduced significantly the secretion of IL-4, which is a cytokine inducing the development of Th2 cells, after splenocytes were stimulated with OVA. However the secretion of IL-5 and IL-13 was influenced weakly or a little. Conclusions These results indicate that S.H could reduce the allergic response through inhibition of antigen-specific IgE and Th2-inducing cytokines. It suggest that S.H may be available clinically for the treatment of allergic patients.

Most inflammatory disorders are usually treated using anti-inflammatory drugs including non-steroidal anti-inflammatory drugs (NSAID) and steroidal anti-inflammatory drugs (SAID). Prolonged uses of NSAIDs and SAIDs may frequently cause adverse side-effects such as nausea, vomiting, diarrhea, constipation, decreased appetite, kidney and liver failure, ulcers, and prolonged bleeding after an injury or surgery. Thus, it is necessarily required to develop a new anti-inflammatory drug with little side-effects. Dandelion (Taraxacum officinale) possesses the therapeutic abilities to eliminate body heat and toxins and to remove swelling and inflammation. In order to verify the anti-inflammatory activity of dandelion, TPA(12-O-tetra decanoylphorbol-acetate)-induced or croton oil-induced acute edema was developed in the mouse ears, and dandelion extract dissolved in acetone was applied to both sides of inflamed ears. It was found that dandelion could significantly reduce the ear swelling, compared to that of non-treated control. In the case of $20{\mu}{\ell}$ application of $100mg/m{\ell}$ dandelion solution (DA-100), its anti-inflammatory effect was comparable to that of indomethacin, a non - steroidal anti-anflammatory drug. Taken together, it could be concluded that topically applied dandelion extract exhibited its potentials as a new drug candidate with an effective anti-inflammatory activity.

Skin irritation caused by retinol and retinoic acid results in mild erythema called as retinoid dermatitis. To develop compounds modulating the retinoid dermatitis, we tried to establish the screening method for retinoid dermatitis. At first we examined the inflammatory cytokine profile in neonatal human dermal fibroblasts which are known to be one of main site of retinoid action. As a result, interleukin-8 (IL-8) and monocytes chemoattractant protein-1 (MCP-1) were significantly produced by all trans retinoic acid (ATRA) and all trans retinol (ATROL) in dermal fibroblasts. Especially the production of MCP-1 was more than that of IL-8. The production of MCP-1 by retinoid was dose-dependently increased, continuing up to 24 hrs. After then using ethacrynic acid (ECA) known to reduce mouse ear edema induced by ATRA, we checked whether ECA suppressed the production of MCP-1. As a result, ECA effectively suppressed the production of MCP-1 in the ATRA- or ATROL-treated-fibroblasts. These results suggested that screening method effectively reflects the in vivo anti-inflammatory activity of ECA. It was reported that citral inhibited the enzyme involved in the conversion of ATROL to ATRA. We showed that citral suppressed the production of MCP-1 in ATROL-treated fibroblasts. We expect these finding might be helpful to find useful compounds modulating the side effects of retinoid or retinoid dermatitis.
