Objectives Hataedock is a Korean herbal medical oral treatment that removes fetal toxic heat and meconium from new born babies. The purpose of this study is to evaluate whether Hataedock treatment of Duchi extracts has anti-inflammation effects on AD (Atopic Dermatitis)-induced NC/Nga mice. Methods After Hataedock treatment of Duchi extracts on days 0, 3-week-old NC/Nga mice were sensitized on days 28, 35, 42 by exposure of DNFB (dinitrochlorobenzene) and were induced to have AD. Immunohistochemistry of NF-${\kappa}B$ p65, iNOS, COX-2 and TUNEL assay of apoptotic body was used to identify changes of skin damages and anti-inflammation effects. Results The alleviate effect of the skin damage and angiogenesis was observed in DT group. The damage of stratum corneum, hyperplasia, edema, infiltration of lymphocytes and distribution of capillary were decreased in DT group. Also, the study results suggested that Hataedock treatment of Duchi extracts in DT group remarkably downregulated levels of NF-${\kappa}B$ p65 by 70% (p < 0.001), as well as COX-2 by 51%, iNOS by 62% (p < 0.001). Additionally, Hataedock treatment of Duchi extracts in DT group up-regulated apoptosis of inflammatory cells by 68% in atopic dermatitis-like skin lesion. Conclusions From the study results, we observed that Hataedock treatment of Duchi extracts alleviates AD through diminishing various inflammatory cytokines in the skin lesions, which are involved in the initial steps of AD development. It is anticipated to have potential applications for prevention and treatment of atopic dermatitis.

Objectives: The root of Lithospermum erythrorhizon Sieb. et Zucc. (Lithospermi Radix, LR) is a kind of heat clearing and blood cooling medicinal herbs. It can clear away heat and cool the blood, reduce toxins and disperse maculae. LR has long been used as efficacious therapy for inflammation, burns, frostbite and skin diseases such as eczema and psoriasis. Methods: In the present study, we investigate anti-allergic and anti-inflammatory effects of LR by using the 1-fluoro-2, 4- dinitrofluorobenzene (DNFB)-induced contact dermatitis mouse model. Results: Topical application of 10 mg/mL of LR effectively inhibited skin lesions induced by repeated paintings with DNFB. Topical application of LR also inhibited hyperplasia, edema, spongiosis and infiltrations of mononuclear cells. In addition, production levels of total immunoglobulin and IgG1 in serum were decreased by using LR in vivo. Conclusions: These data suggest that LR acts as an antiinflammatory agent, improving skin lesions in CD mice.

Chronic joint pain due to loss of cartilage function, degradation of subchondral bone, and related conditions are common plights of an arthritis patient. Antioxidant compounds could solve the problems in arthritic condition. The objective of this study was to evaluate the anti-arthritic activity of D-carvone against complete Freund's adjuvant (CFA)-induced arthritis in rats. D-carvone was orally administered for 25 days at the doses of 30 and 60 mg/kg against CFA-induced arthritic rats. Changes in body weight, paw swelling, organ index, hematological parameters, oxidative stress markers, inflammatory cytokines, and histopathology were recorded. Oral treatment of D-carvone significantly improved the body weight, reduced the paw swelling, edema formation, and organ index in arthritic rats. The levels of white blood cells were reduced, red blood cells and hemoglobin levels were improved in D-carvone treated arthritic rats. Lipid peroxidation levels were lowered whereas enzymatic and non-enzymatic antioxidants were significantly elevated by D-carvone administration against arthritic rats. D-carvone significantly modulated inflammatory cytokine levels and improved the ankle joint pathology against CFA-induced arthritic inflammation. In conclusion, D-carvone proved significant anti-arthritic activity against CFA-induced arthritis in rats.

In the present studies, we examined effect of chamomile flowers extract (CH-Ex), which has traditionally been used as antiphlogistics in Europe for many centuries, against Candida albicans-caused septic arthritis. Candida albicans is a major etiological agent among fungal septic arthritis. This effect was investigated in a murine model of the septic arthritis. That is, mice that were given an emulsion form of C. albicans cell wall (CACW) via footpad route were treated intraperitoneally with the CH-Ex for 3 times every 3 days. Degrees of the footpad-swellings were measured with dial gauger. Data showed that the CH-Ex resulted in the reduction of swelling. For instance, at Day 9 when swelling reached the highest peak, there was up to app. 60% reduction of edema in mice injected with the CH-Ex, compared to that of the control mice that received no treatment (P<0.05). This therapeutic anti-arthritic activity appeared to be mediated by inhibitions of NO (nitric oxide) production from activated RAW264.7 macrophages and proliferation of Con A-treated T lymphocytes. Analysis by HPLC revealed that the CH-Ex contained eight polyphenolic compounds including chlorogenic acid (CRA) and rutin. We have reported the CRA and rutin respectively have the anti-arthritic activity. This correlation implicates that CRA and rutin in the CH-Ex may be responsible for the activity. Combined all together, the CH-Ex has anti-arthritic activity against C. albicans-caused septic arthritis, possibly by inhibiting NO production and proliferation of T cells. This activity seems to be contributed by, at least, CRA and rutin among the compounds in the CH-Ex.

The heartwood of Rhus verniciflua has been known to be effective for lingering intoxication and diabetes mellitus and rheumatoidal arthritis in traditional folk medicine in Korea. We have previously reported that antimutagenic effect of flavonoids derived from the heartwood extract of R. verniciflua, and sulfuretin was the active component. Recently, we have demonstrated that sulfuretin could be an anti-inflammatory principle of the R. verniciflua heartwood partially dependent on cyclooxigenase-inhibitory activity. The present study was undertaken to demonstrate the anti-rheumatoidal arthritis effect of the R. verniciflua heartwood extract, its EtOAc fraction and the main flavonoids, sulfuretin and fustin. All the test samples showed variably significant inhibitory effects on hind paw edema induced by Freund's complete adjuvant reagent (FCA reagent). Sulfuretin treatment with 10 mg/kg (i.p.) for seven days showed the inhibitory effect of 54.2${\pm}$3.0%, Similar trends in RA- and CRP tests, vascular permeability test and trypsin inhibitor test were also found. In addition, no dead mouse was found even when the dose was increased up to 5,000 mg/kg (i.p.). Treatment with 250-1,500 mg/kg on normal rats did not show any marked toxicological significances in the tests of body weight gain, wet weight of organs and hepatic functions. These results suggested that the heartwood of R. verniciflua could be an adequate crude drug for rheumatoidal arthritis with an active component of sulfuretin. The toxicological safety of the heartwood of R, verniciflua is contrasted to known severe allergenic action of the stem bark or its exudate.

This study was conducted to determine the analgesic effect of onion and acanthopanax senticosus mixture extract using the rheumatoid arthritis rat model. Rheumatoid arthritis model was made by the intradermal injection of type II collagen emulsified. Rats were divided into four groups: (1) Sham group(n=5), (2) Control group(administered DW 3 $m{\ell}$/1 day after RA induced, n=7), (3) Experimental group I(administered Onion extractor 600 mg/3 $m{\ell}$/1 day after RA induced, n=7). (4) Experimental group III(administered Onion and Acanthopanax senticosus mixture extractor 600 mg/3 $m{\ell}$/1 day after RA induced, n=7). After that, we examined the arthritic index, paw edema, pain threshold at 1st, 14th, 28th days. And also we examined histopathologic study(safranin-O green), immunohistochamical stain(COX-2) of knee joint at 28th days. Arthritic index, paw edema and pain threshold test were decrease in experimental group I, II than control group. Especially group II was most significantly inhibit effect than the other groups at 28th days. On the histopathologic view, all experimental groups were relieved and reproduced the erosion of arthritic site compared with control group. All experimental groups were COX-2 positive cells in the immunohistological stain of the knee joint were significantly decreased compared with control group. Especially group II was most significantly decreased than the other groups at 28th days. Onion and Acanthopanax senticosus mixture extractor can be used for curing rheumatoid arthritis. Anti-inflammatory effects may be somewhat better in combination of Onion and Acanthopanax senticosus.

Glutaredoxin 1 (GLRX1) has been recognized as an important regulator of redox signaling. Although GLRX1 plays an essential role in cell survival as an antioxidant protein, the function of GLRX1 protein in inflammatory response is still under investigation. Therefore, we wanted to know whether transduced PEP-1-GLRX1 protein inhibits lipopolysaccharide (LPS)- and 12-O-tetradecanoyl phorbol-13-acetate (TPA)-induced inflammation. In LPS-exposed Raw 264.7 cells, PEP-1-GLRX1 inhibited cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), activation of mitogen activated protein kinases (MAPKs) and nuclear factor-kappaB (NF-κB) expression levels. In a TPA-induced mouse-ear edema model, topically applied PEP-1-GLRX1 transduced into ear tissues and significantly ameliorated ear edema. Our data reveal that PEP-1-GLRX1 attenuates inflammation in vitro and in vivo, suggesting that PEP-1-GLRX1 may be a potential therapeutic protein for inflammatory diseases.

Objectives & Methods : The purpose of this study is to observe the effects of Coicis Semen Herbal-acupuncture solution (CS-HAS) at the Joksamni (ST36) on the collagen-induced arthritis in the DBA/1J mouse. The author performed several experiments to analyze the effects of CS-HAS on arthritis; change of the weight; the spleen size and adhesion rate; serum cytokine levels; serum antibody levels; changes of immunocyte counts; the histological changes of joint. Results : In the Coicis Semen Herbal-acupuncture (CS-HA), arthritis index, the incidence of arthritis, and the degree of joint edema were decreased. In CS-HA, there was no weight loss. The size of the spleen, adhesion rate, and the edema and transformation of joint were lowered. In CS-HA, the levels of IL-1${\beta}$, IL-6, TNF-${\alpha}$, IFN-${\gamma}$, IgG, IgM, and anti-collagen II in serum and the levels of IFN-${\gamma}$, IL-4, IL-10 in spleen were significantly decreased. In CS-HA, the expression ratios of $CD45^+$ to $CD3e^+$ and $CD8^+$ to $CD4^+$ were decreased. Also, the overall $CD4^+/CD8^+$ cell ratio was lowered in spleen. Ratios of the $CD4^+/CD25^+$, $CD45^+/CD69^+$ cells were decreased in lymph nodes. In addition, ratios of the $CD3^+/CD69^+$, $CD11b^+/Gr-1^+$ cells were also decreased in synovium. In the histological study, the cartilage destruction and synovial cell proliferation, and collagen fiber destruction were decreased with CS-HA treated group. Conclusions : From the results mentioned above, it is suggested that CS-HA at the ST36 has several significant effects on the collagen-induced arthritis.

Traumatic brain injury (TBI) is a major cause of mortality and long-term disability, which can decrease quality of life. In spite of numerous studies suggesting that Epigallocatechin-3- gallate (EGCG) has been used as a therapeutic agent for a broad range of disorders, the effect of EGCG on TBI remains unknown. In this study, a weight drop model was established to evaluate the therapeutic potential of EGCG on TBI. Rats were administered with 100 mg/kg EGCG or PBS intraperitoneally. At different times following trauma, rats were sacrificed for analysis. It was found that EGCG (100 mg/kg, i.p.) treatment significantly reduced brain water content and vascular permeability at 12, 24, 48, 72 hour after TBI. Real-time PCR results revealed that EGCG inhibited TBI-induced IL-$1{\beta}$ and TNF-${\alpha}$ mRNA expression. Importantly, CD68 mRNA expression decreasing in the brain suggested that EGCG inhibited microglia activation. Western blotting and immunohistochemistry results showed that administering of EGCG significantly inhibited the levels of aquaporin-4 (AQP4) and glial fibrillary acidic protein (GFAP) expression. TBI-induced oxidative stress was remarkably impaired by EGCG treatment, which elevated the activities of SOD and GSH-PX. Conversely, EGCG significantly reduced the contents of MDA after TBI. In addition, EGCG decreased TBI-induced NADPH oxidase activation through inhibition of $p47^{phox}$ translocation from cytoplasm to plasma membrane. These data demonstrate that EGCG treatment may be an effective therapeutic strategy for TBI and the underlying mechanism involves inhibition of oxidative stress.

Objectives : The purpose of this study was to investigate the effects of warm needling at $GB_{30}{\cdot}GB_{34}$ on Complete Freund's Adjuvant(CFA)-induced rheumatoid arthritis in rats. Methods : Arthritis was induced by injecting CFA subcutaneously into the left knee joint and paw. Acupuncture(AT) and warm needling(W-AT0.5, W-AT1.0) were injected at $GB_{30}{\cdot}GB_{34}$, every other day for a total of 5 times beginning on day 10 after the CFA injection. Thereafter, external shape, paw edema, serum aminotransferase and anti-inflammatory factors were assessed, and hematological and histological observations were made. Results : In paw edema volume all 3 groups(AT, W-AT0.5, W-AT1.0) showed significant decrease compared to the CFA control group. In TNF-${\alpha}$ and IL-6, all 3 groups showed significant decrease compared to CFA control group. In AST and ALT all 3 groups showed no significant change. In IL-$1{\beta}$, W-AT0.5 and W-AT1.0, groups showed significant decrease compared to the CFA control group. Leucocyte, erythrocyte and thrombocyte, all 3 groups showed no significant change. In histological observations, all 3 groups were similar to the intact group in terms of synoviocyte, cartilage lacuna and cartilage cells. Conclusions : The results suggest that warm needling at $GB_{30}{\cdot}GB_{34}$, has the effect of suppressing inflammation of CFA-induced rheumatoid arthritis in rats.
