  • This study was evaluated the antiatopic activity of silkworm feces extracts in DNCBinduced NC/Nga atopy mice. It was found that each level of IgE and histamine in blood was significantly decreased in the silkworm feces extracts treatment groups, compared with the DNCB-induced atopy control group. When the silkworm feces extracts was applied to the atopy mice, it could be observed that its skin recovered to normal condition with the skin surface being clean and smooth without any tissue. The results suggest that the application of silkworm feces extracts effect on atopic model through a inhibition of histamine emissions with reducing the levels of blood IgE in NC/Nga atopy mice.

  • Objectives : The aim of this study is to investigate anti-inflammatory activity using various extracts of rice straw (DaoCao) extract (RS).Methods : To investigate the anti-inflammatory effect of RS, we examined the effect of RS on cytokines production on THP-1 cell. Cells were cultured in incubator (37℃, CO25%, 0.5% FBS-RPMI, 1X106cells/ml). One hour after,Dermatophagoides pteronissinus(Dp., 10 ug/ml) was treated into cell and at 6 hour after, each different concentrations(0.1, 1 and 10 ug/ml) of RS were treated. The cells were incubated for 16 hours and harvest the supernatant. The levels of IL-4, IL-5, IL-6, IL-8, MCP-1 and TNF-αwere determined using a commercially available ELISA kit.Results : We investigated whether RS has the inhibition of inflammatory response in Jurkat cells and THP-1 cells. RS suppressed secretion of IL-4, IL-5, and TNF-αinduced by house dust mites in Jurkat cells. It showed significant effects for all concentrations. RS suppressed the increased expression of IL-6, IL-8 and MCP-1 after treatment with mite in THP-1 cells. These results suggest that RS may be used as a valuable agent for treating allergic diseases such as atopy due to its anti-inflammatory property.Conclusions : RS showed significant biological activities with anti-inflammatory in the human T cells. These results suggest that RS may be used as a valuable agent for treating allergic diseases such as atopy due to its anti-inflammatory property. In terms of Korean traditional medicine, we expect the results to contribute to building of EBM (Evidence-Based Medicine).

  • This study examined several dyeing properties, physiological responses and comfort sensation of cotton knit underwear dyed with bamboo charcoal. The cotton knit underwear dyed with bamboo charcoal and treated with chitosan showed 99.9% antibacterial property and improved deodorization, and colorfastness. Eight children with atopic dermatitis worn underwear dyed with bamboo charcoal during 4 months. Their parents reported fewer itches of children. Wearing cotton knit underwear dyed with bamboo charcoal and non-dyed with bamboo charcoal respectively, these eight children rested for 20 minutes, then exercised for 10 minutes, and then rested for 30 minutes in the room maintained $28{\pm}1^{\circ}C$ and $50{\pm}5%R.H.$ Children's rectal temperature, skin temperature and microclimate inside garment of two types of cotton knit underwear were compared. As a result, the rectal temperature and skin temperature were higher when children were wearing underwear dyed with bamboo charcoal than non-dyed underwear. The microclimate temperature and microclimate humidity at the back of children were lower when children with underwear dyed with bamboo charcoal exercised and recovered.

  • This study investigated the effects of mycelium and culture supernatant of Cordyceps ochraceostromat(Co) on air way hyper-responsiveness, pulmonary immune cell infiltration, and Th2 cytokine expression in animal models of atopy and asthma. After ConA(+/-) activation of mouse primary spleen cells, decreased IL-4 and IL-13 cytokine production were seen in the presence of Co mycelium extracts and culture supernatant. The asthma model involved mice sensitized to ovalbumin by i.p. injection treatment; Co mycelium extract was also injected. The atopy model was the dinitrofenylbenzene-treated mouse ear. Ear thicken ing induced by DNFB was decreased by Co mycelium extract, and the extract also inhibited lung cell infiltration in ovalbumin-induced asthmatic mice. The results thus indicated that the Co mycelial extract reduced the undesirable immune responses seen in asthma and atopy.

  • Oxidative stress has been implicated in cutaneous damage in various inflammatory skin diseases, including atopic dermatitis (AD). Atoberry is the herb medicine extract which is composed with Spirodelae Herba, Xanthii Fructus, Houttuyniae Herba, Taraxaci Herba, Retinervus Luffae Fructus, Platycodi Radix, and Scutellariae Radix. In this study, we investigated the antioxidant and anti-inflammatory effects of Atoberry in AD-like skin lesion NC/Nga mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinse (Df) extract. Atoberry significantly increased electron donating ability (DPPH), nitrite scavenging (NO) and superoxide dismutase (SOD) activities in dose dependant. Topically applied Atoberry significantly reduced clinical severity score, ear thickness and histological grade in AD-like skin lesion NC/Nga mice. In addition, the serum levels of IgE, NO and prostaglandin E2 were significantly reduced by Atoberry. Futhermore, skin tissue levels of SOD, catalase and glutathione peroxidase (GPx) were significantly reduced by Atoberry. These results demonstrate that topical application of Atoberry may be improve the AD-like skin lesion by antioxidant and anti-inflammatory effects.

  • This study aims to evaluate the anti-inflammatory effect of Coptidis Rhizoma (CR) extract for atopic dermatitis through maintaining skin barrier and regulating Th2 cell differentiation. We divided NC/Nga mice into 3 groups as follows; atopy-like dermatitis induced group with CR treatment (CT, n=10), no treatment group(Ctrl), atopy-like dermatitis elicited group(AE). Atopy-like dermatitis was induced to NC/Nga mice by sensitizing with dermatophagoides farinae(DfE) on 7, 8, 9, 11, 12, and 13th week. After inducing atopic dermatitis, CR extract was administered 20 mg/kg daily for the experimental duration to the CT group. We measured the integrity of lipid layers in the epidermis and Th2 differentiation through immunohistochemical staining against filaggrin, loricrin, IL-4, and IL-13. We also measured the distribution of subcutaneous collagen fibers by the Masson's trichrome staining. Administration of CR significantly inhibited the reduction of lipid layers in the skin that caused atopy. The expression of IL-4, IL-13, each of which is a cytokine secreted by T helper type 2 (Th2) cells, was markedly suppressed in the CT group as compared with AE group (p<0.05). CR treatment also decreased the expression of iNOS, $p-I{\kappa}B$. Atopic dermatitis induced dermatological damage to skin, such as hyperplasia of epithelium, and capillary proliferation was significantly reduced by CR administration. CR effectively inhibited the thinning of the skin barrier and inflammatory responses in atopic dermatitis-induced mice. In particular, it showed anti-inflammatory effects by reducing the expression of IL-4 and IL-13, Th2 cell cytokines, which play a crucial role in development of atopic dermatitis. Therefore, CR can be a good candidate to ameliorate and treat atopic dermatitis.

  • Objectives : Consumption of fermented foods has been known to alleviate some of the symptoms of atopy and may limit allergy development, while there are also many medicinal herbs proved to be effective for immunologically-mediated diseases. In this study, we introduced modern zymology to ferment some herbs to see if fermentation has the possibility of increasing the anti-inflammatory effects of medicinal herbs. Interleukin-4 (IL-4) and interferon-gamma $(INF-\gamma)$ have been demonstrated to be the main factors in the pathology of allergic diseases. Methods : We measured the levels of IL-4 and $INF-\gamma$ on concanavalin A-induced BALB/c mice spleen cells, which were subsequently treated with fermented and unfermented herbs. We then compared the fermented groups with unfermented groups to see if the anti-inflammatory effects of the herbs were influenced by fermentation. Results and Conclusions : Our results showed that fermentation had the potential to increase the anti-inflammatory effects of some medicinal herbs, and Astragalus membranaceus and Salvia miltiorrhiza would be the most suitable medicinal herbs for fermentation among the herbs in this study.
