Objectives: Notopterygium incisum(N. incisum) and Saposhnikovia divaricata(S. divaricata) have been clinically used in traditional oriental medicine for treatment of inflammatory diseases. Also, a herbal mixture prepared with N. incisum and S. divaricata has been strongly linked to the anti-inflammatory effect. In this study, we evaluate the synergistic anti-inflammatory effect of N. incisum and S. divaricata. Methods: For evaluating the anti-inflammatory activity of a herbal mixture of N. incisum and S. divaricata in vivo, we measured the changed ear thickness in 12-O-tetradecanoyl-phorbol-13-acetate(TPA)-induced mouse ear edema model after topical application of herbal mixture. In addition, the levels of markers for inflammation, such as tumore necrosis factor (TNF)-${\alpha}$, interleukin (IL)-1${\beta}$, and nitric oxide(NO), were determined by ELISA assay in lipopolysaccharide-stimulated Raw 264.7 cells. Results: We reported that water extracts of N. incisum and S. divaricata combination significantly inhibited the mouse ear edema induced by TPA. Moreover, the water extracts of N. incisum and S. divaricata combination exhibited synergistic effects in down-regulating IL-1${\beta}$ level, but not TNF-${\alpha}$ and NO. Conclusions: These results suggest that combined treatment of N. incisum and S. divaricata, based on seven methods in prescription compatibility, has a synergistic effect in down-regulating inflammatory response both in vivo and in vitro models. Especially, it seems that IL-1${\beta}$ is a one of main target of the mixture of N. incisum and S. divaricata on anti-inflammatory activity.

Objectives : The water extract of Hwangnyeonhaedok-tang (HHT), composed of the Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus has been traditionally used to treat fever, inflammation, gastritis and hypertension in east asia. However, little is known about the ameliorative effects of HHT on atopic dermatitis. Therefore, the purpose of this study was to investigate the therapeutic effect of HHT on atopic dermatitis Methods : We investigated the inhibitory effects of HHT on the production of proinflammatory cytokines in rat peritoneal mast cells (RPMCs), on the scratching behavior in ICR mice, and on atopic dermatitis symptoms in 2,4-dinitrofluorobenzene (DNFB)-induced atopic dermatitis-like model hairless mice. Results : Levels of TNF-${\alpha}$ and IL-$1{\beta}$ increased by PMA plus A23187 co-treatment were significantly inhibited by HHT in a dose-dependent manner. HHT also inhibited the histamine release from RPMCs stimulated by compound 48/80, which promotes histamine release. The oral administration of HHT reduced the scratching behavior induced by compound 48/80 and histamine in ICR mice. Furthermore, the intradermal treatment of HHT reduced the ear edema, skin lesions, and atopic molecular marker (IgE and IL-4) in DNFB-induced atopic dermatitis model mice. Conclusions : These results suggest that HHT may be used as a potential treatment for AD as a prescription for treatment of atopic dermatitis.

본 연구는 COHEE의 항염증 효과를 확인하기 위한 실험으로써 pro-inflammatory cytokine의 분비량 및 iNOS, COX-2, NF-κB와 MAPKs의 발현량을 관찰하였다. 먼저 MTT assay를 통해 COHEE가 세포 생존율에 있어 독성을 나타내지 않음을 확인한 후 동일한 농도로 추후실험을 진행하였다. COHEE에 의해 NO 분비량이 농도 의존적으로 감소하였으며 IL-6, TNF-α 및 IL-1β의 분비량 또한 유의적으로 감소하였다. 특히 100 μg/ml의 농도에서 LPS 단독처리구인 대조구에 비하여 IL-6, TNF-α 및 IL-1β의 분비량을 각각 66%, 43% 및 93% 억제시켰다. 이러한 결과가 전염증성 매개인자의 전사인자인 NF-κB와 MAPKs 경로에 의한 것인지 확인하기 위하여 발현량을 관찰한 결과, COHEE가 LPS 처리에 의해 현저히 증가한 단백질의 발현을 농도 의존적으로 유의성 있게 억제하였다. 또한 COHEE는 croton oil로 부종을 유발한 마우스모델에서 귀부종 억제효과를 나타내었고 250 mg/kg 농도에서 조직의 경피 및 진피 두께의 발달을 prednisolone 10 mg/kg 처리구와 유사한 정도까지 현저히 억제시키고 염증성 세포인 mast cell의 침윤 억제 효과도 확인하였다. 이를 통해 COHEE는 염증 반응의 전사인자인 NF-κB의 발현을 조절함으로써 iNOS와 COX-2의 발현을 억제하고 그에 따라 전염증성 매개인자인 NO, IL-6, TNF-α 및 IL-1β의 분비를 억제하여 항염증 활성을 가지는 것을 확인하였으며, 이 결과를 종합해볼 때, COHEE가 염증 치료제로써의 소재로 이용될 가치가 충분할 것으로 사료된다.

This study was designed to elucidate the antiinflammatory, cardiovascular, antithrombotic, and analgesic effect of Sambitang. The antiinflammatory effects was measured by the method of carrageenin induced edema, protein leakage test using CMC-pouch, and the effect of Sambitang on the cardiovascular system was observed by the change of flow rate of Ringer solution in the vascular system in the ear of rabbit, and the contraction and dilatation of rat tail artery. Death rate, platelet aggregation, plasma coagulation activity was observed for the measurement of the anticoagurative effect of Sambitang, and the analgesic effect was measured by the acetic acid method and hot plate method. The result was as follows: 1. Sambitang administration, edema and protein leakage was significantly decreased. 2. The drug increased the auricular blood flow in rabbit. 3. The drug relaxed the artery contraction by pretreated norepinephrine in rat. 4. The drug inhibited the death rate of mouse which was led to thromboembo- lism by serotonin and collagen. 5. The drug inhibited the platelet aggregation in rat. 6. The drug prolonged the prothrombin time and activated partial thromboplastin time on the test of plasma coagulation factor activity in rat, but was not valuable. 7. The slight anagesic effect of Sambitang extract was confirmed by the observation of writhing syndrome, paw licking time, and escape time.

Eleven polyhydroxyursane triterpenoids (PHUTs) were tested to determine their cytoprotective, immunosuppressive and anti-inflammatory effects. To compare the bioactivities of $19{\alpha}$-hydroxyursane-type triterpenoids {23-hydroxytormentic acid (6), its methyl ester (7), tormentic acid (8), niga-ichigoside $F_1$ (9),euscaphic acid (10) and kaji-ichigoside $F_1$ (11)} of the Rosaceae crude drugs (Rubi Fructus and Rosa rugosae Radix) with PHUTs possessing no $19{\alpha}-hydroxyl$ of Centella asiatica (Umbelliferae), the four PHUTs, asiaticoside (1), madecassoside (2), asiatic acid (3), and madecassic acid (4) were isolated from C. asiatica and 23-hydroxyursolic acid (5) from Cussonia bancoensis. Cytoprotective effects were assessed by measuring cell viabilities against cisplatin-induced cytotoxocity in $LLC-PK_1$, cells (proximal tubule, pig kidney) to determine whether these agents have protective effects against nephrotoxicity caused by cisplatin. The inhibitory effect of 11 PHUTS on nitric oxide (NO) and prostaglandin $E_2\;(PGE_2)$ were evaluated by measuring nitrite accumulation in lipopolysaccharide (LPS)-induced macrophage RAW 264.7 cells, and their anti-inflammatory effects were tested in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced mouse ear edema model. Six MHUTs (compounds 1, 2, 4, 6, 10, and 11) exhibited higher cell viabilities during cisplatin-induced cytotoxicity testing even at a concentration of $200\;{\mu}g/ml$ than cisplatin only-treated group, suggesting that ese compounds have the potentcytoprotective efffcts. Compounds 1 and 3 of the C. asiatica and niga-ichigoside $F_1$ exhibited no inhibitory effect on NO and/or $PGE_2$ production whereas other PHUTs produced mild to significant NO and/or $PGE_2$ production.The four compounds (2, 5, 9, and 10) potently inhibited mouse ear edema induced by TPA whereas two compounds (1 and 3) had no activity in this test. These results suggest that many PHUTs are potentchemopreventives. Structure-activity relationship (SAR) was also discussed in each assay with regard to the significant role of OHs at the position of 2, 3, 6, 19, and 23 and to the glycoside linkage at the 28-carboxyl.

Objectives : Platycodon Root is frequently used in traditional medicine to treat inflammatory diseases of the throat. The purpose of this study was to characterize the effect of the EtOH extract of fermented Platycodon grandiflorum on the ameliorative effects on the Antipruritic Effect of atopic dermatitis mouse model induced by compound 48/80 and ovalbumin (OVA)-induced allergic responses in mice. Methods : In the present study, we examined the anti allergic effect of Platycodon grandiflorum (PR) and its fermented production (FPR) in several mouse model. We measured acute ear edema in a mouse model caused by TPA and consecutively histological change of Ear tissue was observed by hematoxylin and eosin (H&E) staining. and also Scratching behaviors by compound 48/80 was investigated. The levels of allergic mediators such as immunoglobulin (Ig) E, and anti-oxidant markers such as SOD and MDA in the sera of OVA induced allergic mice were measured by enzyme-linked immunosorbent assay. Results : FPR inhibited compoud 48/80-induced scratching behavior in mice, as well as acetic acid-induced writhing in mice. The anti-scratching behavioral effect of FPR was more potent than PR. FPR extract significantly decreased the serum levels of IgE and MDA compared with those of OVA control group. Conclusions : These results indicate that Anti allergic effect of Platycodon grandiflorum is enhanced by fermentation with Saccharomyces cerevisae and FPR may be useful for protection from the itching reactions, which are IgE-mediated representative skin allergic diseases.

Atopic dermitiis(AD) is a chronic inflammatory skin disease, which requires safe and effective medicinal therapy. Over production of Th2 cytokines and chemokines as well as IgE, which are mediated by highly activated immune cells, have been considered as pathologic factors in this disease. We found that Gamipaidok-san(GPDS), which is a traditional herbal medicine clinically prescribing for atopic dermitis patients in the hospital, has suppressive effects on the development of DNC8 induced dermatitis in Nc/Nga atopic model. Oral administration of GPDS at the concentration of 250 mg/Kg for 12 weeks significantly suppressed the clinical severity of the dermatitis including pruities, edema, eczematous and dryness. Histological examination revealed that thickness of dermis and epidermis were considerably reduced, and the number of infiltrated inflammatory immune cells including mast cells, CCR3+, and CD4+ T cells were decreased in the affected skin and ear, and consistantly, the number of CD3+/CCR3+ cells in Iymph nodes were decreased. The levels of Th2 cytokines produced by activated splenocyte from atopic mice were also down-regulated by GPDS. Furthermore, the serum levels of IgE were considerably reduced, which accompanied by a decrease in the number of B220+IgE+ B cells in the Iymph nodes. Taken together, these results suggested that oral administration of GPDS, a traditional herbal medicine, has suppressive effects on atopic dermitis of Nc/Nga mouse by the modulation of the immune system, therefore GPDS has potential as a natural therapeutic for treatment of atopic dermatitis.

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.

Objectives Hataedock is the treatment that dispels toxic heat and meconium gathered at the fetus for the new born baby by orally administered herbal extracts. The purpose of this study was to evaluate whether Hataedock alleviate inflammatory skin damages in AD-induced NC/Nga mice through regulating of skin barrier maintain and Th2 differentiation. Methods We established an AD model in the 3-week-old NC/Nga mice through the repeated application of DNFB (dinitrochlorobenzene) on days 28, 35, 42 after Hataedock treatment which was orally administered. We identified the changes of skin barrier and Th2 differentiation through the histological and immunohistochemical changes of protein kinase C (PKC), interleukin (IL)-4, degranulated mast cell, Substance P and MMP-9. Results Our results suggested that Hataedock treatment significantly down-regulated levels of PKC by 82% (p < 0.001), as well as IL-4 by 56% (p < 0.001). Hataedock also suppressed mast cell infiltration, ear edema formation. and Substance P in the tissue of NC/Nga mice were decreased by 57% (p < 0.001), and MMP-9 by 55% (p < 0.001). Conclusions These results suggest that Hataedock alleviates AD through the down-regulation of PKC and Th2 cytokines, which are involved in the initial steps of AD development. Hataedock have potential application for the treatment of AD.
