Atopic dermatitis (AD) usually develops in patients with an individual or family history of allergic diseases, and is characterized by chronic relapsing inflammation seen specially in childhood, association with IgE hyperproduction and precipitation by environmental factors. and wished to examine closely effect that Polygonum multiflorum isolated PM-E and PM-70M orally adminstration used to atopy dermatitis disease patient get in atopy eruption control experimentally. Atopic dermatitis is a chronically relapsing inflammatory skin disease. Animal models induced by relevant allergens play a very important role in the elucidation of the disease. This study was investigated the anti-allergic effect of PM-E and PM-70M on BMAC induced atopic dermatitis in NC/Nga mice. We summerized as the follow. PM-E and PM-70M significantly reduced the skin number of total cell number, CD4⁺ and CD11b⁺/Gr-1 cell compared with positive control and decreased the invasion of CD4⁺ cell in dorsal skin tissue compared with positive control group by using immunohistochemical staining and chemokine such as eotaxin and CCR3 compared with positive control group. PM-E and PM-70M markedly suppressed invasion and edema of leukocytes and mast cell in dorsal skin. Taken together, these findings suggested that PM-E and PM-70M has an anti-allergic activity and this might be useful for the clinical application to treat allergic diseases such as atopic dermatitis.

Atopic dermatitis (AD) is a chronically relapsing pruritic inflammatory skin disease. To find new anti-inflammatory products for skin inflammatory disease such as AD and contact dermatitis, we produced the effective microorganism fermentation substance (EM-S) by fermentation of medicinal plants with effective microorganisms including photosynthetic bacteria, lactic acid bacteria and yeast, screened the effects of EM-S on NC/Nga model mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinae (Df) extract. Topically applied EM-S significantly reduced clinical severity score, ear thickness and histological grade in AD-like NC/Nga mouse model by Df antigen sensitization. In addition, the serum IgE and Th2 chemokine levels (TARC/CCL17, MDC/CCL22 and CTACK/CCL27) were significantly reduced by EM-S. Futhermore, skin tissue expressions of Th2 chemokines were significantly reduced by EM-S. These results demonstrate that topical application of EM-S may be improve the AD-like skin lesion by suppressing IgE and Th2 chemokines.

Objectives: This study aimed to investigate the effects of Amyda sinensis (AS) on allergic inflammation mechanism related atopy dermatitis. Methods: To investigate the effects of AS, We study inhibitory effect of AS on the levels of pro-inflammatory cytokines released from Raw264.7 cell stimulated with LPS (lipopolysaccaride), and EoL-1, THP-1, Jutkat cell stimulated with DP (Dermatophagoides pteronyssinus), and LPS indused acute inflammatory BALB/c mouse model. Result: AS reduced the levels of IL-$1{\beta}$ released from Raw264.7 cell stimulated with LPS at 20 ug/ml, 5 ug/ml concentration, and reduced the levels of IL-6 in a dose-dependent. AS significantly reduced the levels of MCP-1 released from EoL-1 cell stimulated with DP (Dermatophagoides pteronyssinus) at all the concentration, and significantly reduced the level of IL-8 at 0.1 ug/ml concentration. AS significantly reduced the levels of MCP-1 released from THP-1 cell stimulated with DP (Dermatophagoides pteronyssinus) at 1 ug/ml concentration, and reduced the level of IL-6 in a dose-dependent. AS significantly reduced the levels of IL-4 released from Jutkat cell stimulated with DP at all the concentration, and significantly reduced the level of IL-5 at 0.1 ug/ml. 1 ug/ml concentration,. and reduced the level of TNF-${\alpha}$ in a dose-dependent. AS significantly reduced the levels of TNF-${\alpha}$, IL-6, IL-$1{\beta}$, in LPS indused acute inflammatory BALB/c mouse model, in a dose-dependent. Conclusion: These result suggested that AS has suppressive effect on pro-inflammatory cytokines in various cell lines through the regulation of immune system. AS could be applied on the medicinal sources for treatment of immune abnormal diseases such as atopy dermatitis afterward.

Objectives : In a previous study, we have shown that Gagam-Gongjin-Dan(GGD) has an inhibitory effect on the ovalbumin-induced immune responses and a hepatoprotective effect on actaminophen-induced liver injury in Balb/c Mice. However, the possible anti-inflammatory effect of GGD extract for inflammatory mediators was not reported. Therefore, the purpose of this study was to investigate an inhibitory effects of GGD extract against lipopolysaccharides(LPS) induced inflammatory mediators in mouse peritoneal macrophages. Methods : GGD extract was prepared by extracting with methanol for 7 days. The extract was freeze-dried following filtration through vacuum distillation system. Accumulated nitrite, an oxidative product of nitric oxide(NO), was measured in the culture medium by the Griess reaction. The levels of prostaglandin $E_2(PGE_2)$, interleukin-$1{\beta}$(IL-$1{\beta}$), tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) were measured by enzyme-linked immunosorbent assay. The expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2(COX-2) were measured by Western blot analysis. Results : GGD extract (50-$400\;{\mu}g$/ml) per se had no cytotoxic effect in LPS-stimulated peritoneal macrophages. GGD extract dose-dependently reduced NO, $PGE_2$, IL-$1{\beta}$ and TNF-${\alpha}$ production and COX-2 activity caused by stimulation of LPS. The levels of iNOS and COX-2 protein expressions were markedly suppressed by the treatment with GGD extract in a dose dependent manner. Conclusions : These results suggest that GGD extract has an anti-inflammatory effect against LPS-induced inflammatory mediators in peritoneal macrophages, these properties may contribute to inflammation disease care.

Sophorae Radix (SFR) is known as a therapeutic drug that has been used in Oriental traditional medicine for the treatment of skin and mucosal ulcers, gastrointestinal hemorrhage, diarrhea, inflammation and arrhythmia. In the present study, we examined the effects of the aqueous extract of SFR on anti-inflammation, anti-allergic and anti-oxidant effect in various cell lines; they include mouse lung fibroblast cells (hFCs), human mast cells (HMC-1), human monocytic cells (THP-1), and RAW 264.7 cells. Treatment with SFR extract at a concentration of 250 ${\mu}g$/ml for 24h showed no significant decrease in the survival rate of the hFCs. SFR decreased the mRNA expression of IL-8, TNF-$\alpha$, and IL-6 in HMC-1 cells. SFR extract treatment significantly inhi-bited the protein expression of IL-6 and, IL-8 induced by mite in THP-1 cells and it also did MCP-1 expression. We examined the alternation of histamine release in HMC-1 cells for investigating anti-allergic effect of SFR. Histamine secretion decreased after the treatment with SFR. In addition, SFR extract treatment at a concentration of 10 ${\mu}g$/ml, 100 ${\mu}g$ /ml, and 200 ${\mu}g$/ml lowered the $\beta$-hexosaminidase to 10.3%, 21.7%, and 50.8%, respectively. IC50 of SFR extract in RBL-2H3 cells was 196.85 ${\mu}g$/ml. Both activity of NF-$\kappa$B promoter in RBL-2H3 cells significantly diminished after the dose-dependent treatment of SFR. Therefore, our results indicate that SFR has anti-inflammatory and it may be useful for treating allergic diseases such as atopic dermatitis.

The purpose of this study was to investigate the anti-allergy activities of persimmon leaf extract (PLE) on a phthalic anhydride (PA)-induced allergic mouse model. A human leukemic mast cell line (HMC-1) was used to examine the inhibitory activity of PLE on the histamine release by human leukemic mast cells. PLE inhibited histamine release from HMC-1 cells in response to cross-linkage of high-affinity IgE receptor-${\alpha}$ ($Fc{\varepsilon}RI{\alpha}$). Additionally, a PA-induced allergic mouse model was used to investigate the effects of PLE in vivo. Mice were orally administrated with or without PLE of single dose (250 mg/kg/day) for 31 days. Oral intake of PLE significantly inhibited passive cutaneous reactions. Oral administration of PLE to PA-induced allergic mice also led to a striking suppression of the development of contact dermatitis, ear swelling and lymph node weight. In addition, PA-specific IL-4 production of draining lymph node cells was markedly diminished by PLE oral administration, but not IFN-${\gamma}$. Furthermore, PLE treatment suppressed PA-induced thymus and activation-regulated chemokine (CCL17) and cutaneous T cell-attracting chemokine (CCL27) expressions in ear tissues. Based on these results, we suggest that PLE may have therapeutic potential as an effective material for management of irritant contact dermatitis or related inflammatory diseases.
