SCRT (Sochungyong-tang) has been used for immune disease in human. The purpose of this study was effect of Helper T cell, major regulator of immune system. Spleen cell from 8 week BALB/c mice were cultured in SCRT containing medium without activation for 48 h. The MTS assay and flow cytometry revealed that SCRT treated Iympocyte were non-effect in percentage of CD4+ T cell. Subsequently CD4+ T cell were isolated and cultured in SCRT containing medium. SCRT were non-effective on CD4+ T cell without any involvement of APC. In order to evaluate the direct effect of SCRT on Helper T cell, CD4+ T cell isolated after 48 h of culture in SCRT containing medium and activated with and without anti-CD3/anti-CD28 activation for 48 h. A lower level of CD69 was observed in SCRT treated cells in flow cytometry analysis. Subsequently Using RT-PCR analysis the expression of mRNA for IL-2, INF-γ are upregulated and, IL-4 is downregulated in CD4 T cell. The result suggests that SCRT makes Th1 significantly increased and Th2 relatively inhibited. The results suggest that SCRT potentiate Th1 cell and decrease Th2 development at the same time, which is believed to be bemeficial for IgE-mediated responses.

Background: The prevalence of allergic inflammatory diseases such as atopic dermatitis (AD), asthma, and allergic rhinitis worldwide has increased and complete recovery is difficult. Korean Red Ginseng, which is the heat-processed root of Panax ginseng Meyer, is widely and frequently used as a traditional medicine in East Asia. In this study, we investigated whether Korean Red Ginseng water extract (RGE) regulates the expression of proinflammatory cytokines and chemokines via the mitogen-activated protein kinases (MAPKs)/nuclear factor kappa B ($NF-{\kappa}B$) pathway in allergic inflammation. Methods: Compound 48/80-induced anaphylactic shock and 1-fluoro-2,4-dinitrobenzene (DNFB)-induced AD-like skin lesion mice models were used to investigate the antiallergic effects of RGE. Human keratinocytes (HaCaT cells) and human mast cells (HMC-1) were also used to clarify the effects of RGE on the expression of proinflammatory cytokines and chemokines. Results: Anaphylactic shock and DNFB-induced AD-like skin lesions were attenuated by RGE administration through reduction of serum immunoglobulin E (IgE) and interleukin (IL)-6 levels in mouse models. RGE also reduced the production of proinflammatory cytokines including $IL-1{\beta}$, IL-6, and IL-8, and expression of chemokines such as IL-8, thymus and activation-regulated chemokine (TARC), and macrophage-derived chemokine (MDC) in HaCaT cells. Additionally, RGE decreased the release of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), $IL-1{\beta}$, IL-6, and IL-8 as well as expressions of chemokines including macro-phage inflammatory protein $(MIP)-1{\alpha}$, $MIP-1{\beta}$, regulated on activation, normal T cell expressed and secreted (RANTES), monocyte chemoattractant protein (MCP)-1, and IL-8 in HMC-1 cells. Furthermore, our data demonstrated that these inhibitory effects occurred through blockage of the MAPK and $NF-{\kappa}B$ pathway. Conclusion: RGE may be a useful therapeutic agent for the treatment of allergic inflammatory diseases such as AD-like dermatitis.

The aim of this study was to investigate the effect of SR-HA(Stemonae Radix-herbal acupuncture) at Joksamni(ST36) on ovalbumin-induced asthma in mice. C57BL/6 mice were sensitized and challenged with OVA(ovalbumin) for 12 weeks(once a week). One of the two experimental groups was just treated with needle-prick on Joksamni(ST36) and the other group was treated with 1% concentrations of SR-HA at Joksamni(ST36) for the later 8 weeks (3times/week). The weight of lung of the mice group treated with SR-HA decreased significantly compared with those of control group, and significantly increased compared with those of normal group. The total cells of lung of the mice group treated with SR-HA decreased significantly compared with those of control group. Total leukocytes and eosinophils in BALF of the mice group treated wtih SR-HA decreased significantly compared with those of control group. Eosinophils in BALF of the mice group treated wtih SR-HA in Photomicrographs decreased significantly compared with those of control group. According to histological analysis of lung sections, adhesion of collagen in SR-HA decreased significantly compared with that of control group. The concentration of IgE, IL-4, IL-5 in BALF of the mice group treated with SR-HA decreased significantly compared with that of control group, and significantly increased compared with those of normal group. The concentration of IL-4, IL-5, IL-13 in serum of the mice group treated with SR-HA decreased significantly compared with that of control group, and significantly increased compared with those of normal group. The number of Gr-1+/CDl1b+, CO3-/CCR3+, CD4+, CD8+, CD3e+/CD69+ cells in the lungs of the mice group treated with SR-HA decreased significantly compared with those of control group. These results suggest that Stemonae Radix Herbal-acupuncture at Joksamni(ST36) in 057B146mice may be an effective part to OVA-induced asthma in C57BL/6 mice.

The inhibitory effects of 25 polyphenols against in vitro allergic reactions were compared using biochemical and cell assays. Three polyphenols including curcumin, gallic acid, and quercetin suppressed the release of $\beta$-hexosaminidase from ionophore A23187-stimulated RBL-2H3 cells more effectively (>50% inhibition at $100{\mu}M$ concentration). They were found to have potencies in suppressing the release of histamine not only from ionophore A23187-, but also from immunoglobulin E (IgE)-stimulated RBL-2H3 cells. Moreover, such suppressive effects of the three polyphenols were also observed in A23187 plus PMA-costimulated rat peritoneal mast cells. The extent of inhibition were quantified as the respective polyphenol concentration that inhibit 50% ($IC_{50}$) of $\beta$-hexosaminidase or histamine release, showing an inhibition tendency with decreasing order of curcumin>gallic acid>quercetin. Down-regulation of $Ca^{2+}$ influx was suggested as the cause of the inhibition of $\beta$-hexosaminidase and histamine releases in these cells. The immune process inhibition was confirmed by the observed reduction in the gene expressions and release of pro-inflammatory cytokine tumor necrosis factor (TNF)-$\alpha$, interleukin (IL)-$1\beta$, and IL-4, due probably to antioxidant activity of the polyphenols. These findings illustrate that curcumin, gallic acid, and quercetin may be beneficial against allergic inflammatory diseases.

To evaluate the antiatopic effect of Korea red ginseng (RG, steamed root of Panax ginseng CA Meyer, Family Araliaceae) fermented by Bifidobacterium longum H-1 (FRG), its inhibitory effect on passive cutaneous anaphylaxis (PCA) reaction and itching in mice was measured. FRG and its ingredient saponin fraction (FSF) potently inhibited PCA reaction and scratching behaviors. FRG at a dose of 200 mg/kg and FSF at a dose of 50 mg/kg significantly inhibited the scratching frequency by 45% and 47%, respectively. FRG and FSF also inhibited the degranulation and protein expression of tumor-necrosis $factor-{\alpha}$ and interleukin-4 of RBL-2H3 cells induced by IgE-complex. However, polysaccharide fraction of FRG (FPF) weakly inhibited it, compared with FSF. The inhibitory effect of FRG against PCA reaction and scratching behaviors more potently inhibited than that of RG. Based on these findings, FRG can improve allergic skin disorders atopic dermatitis by the regulation of $TNF-{\alpha}$, and IL-4 produced by mast cells and basophils and its degranulation.

This study was conducted to investigate the anti-inflammatory effects of Pruns mume, Schisandra chinensis, Chaenomeles sinensis-- Prunus mume mixtrue (PM) treatment on colitis induced in mice by dextran sodium sulfate (DSS) treatment. A total of 25 male BALB/c mice (average weight $20.7\;{\pm}\; 1.6 \;g$) were divided into 5 treatment groups and fed a commercial diet (A), PM administration (B), commercial diet + induced colitis by DSS (C), PM administration + induced colitis by DSS (D) and sulfasalazine + induced colitis by DSS (E). We found that PM treatment (D) and sulfasalazine (E) decreased the expression of $TNF-{\alpha}$ and COX-2 compared to the DSS-induced colitis group (C). The expression of IL-4, STAT6, $IFN-{\gamma}$, STAT1 was decreased in group D and group E compared to the colitis group (C), COX-2 and STAT1 were more decreased in group D. The serum IgE levels decreased in the PM treatment groups (C and D) compared to the non-PM treatment groups (A and B) although there was no significant difference between the PM treatment groups. It is notable that a therapeutic application of the PM extracts ameliorated DSS-induced colitis in mice.

Staphylococcus aureus (S. aureus) is known to induce apoptosis of host immune cells and impair phagocytic clearance, thereby being pivotal in the pathogenesis of atopic dermatitis (AD). Adipose-derived stem cells (ASCs) exert therapeutic effects against inflammatory and immune diseases. In the present study, we investigated whether systemic administration of ASCs restores the phagocytic activity of peripheral blood mononuclear cells (PBMCs) and decolonizes cutaneous S. aureus under AD conditions. AD was induced by injecting capsaicin into neonatal rat pups. ASCs were extracted from the subcutaneous adipose tissues of naïve rats and administered to AD rats once a week for a month. Systemic administration of ASCs ameliorated AD-like symptoms, such as dermatitis scores, serum IgE, IFN-γ⁺/IL-4⁺ cell ratio, and skin colonization by S. aureus in AD rats. Increased FasL mRNA and annexin V⁺/7-AAD⁺ cells in the PBMCs obtained from AD rats were drastically reversed when co-cultured with ASCs. In contrast, both PBMCs and CD163⁺ cells bearing fluorescent zymosan particles significantly increased in AD rats treated with ASCs. Additionally, the administration of ASCs led to an increase in the mRNA levels of antimicrobial peptides, such as cathelicidin and β-defensin, in the skin of AD rats. Our results demonstrate that systemic administration of ASCs led to decolonization of S. aureus by attenuating apoptosis of immune cells in addition to restoring phagocytic activity. This contributes to the improvement of skin conditions in AD rats. Therefore, administration of ASCs may be helpful in the treatment of patients with intractable AD.
