This research was performed in order to investigate the anti-inflammatory effects of Bupleuri Radix(BR) on the Immune response in vitro. Cellular proliferation and cytokine production were measured in mast cells or mouse B cells or CD4 Th cells. BR water extract inhibited the secretions of TNF-$\alpha$ and IL-6 in PMA/A23187 stimulated HMC-1 cells. It increased proliferation but did not affect the expressions of CD69 or CD23 in rIL-4/anti-CD40 activated S cells. BR reduced surface IgE expression and secreted IgE but increased the production of IL-4, IFN-$\gamma$ and IgG1 in the same cells. BR caused an increase in proliferation in anti-CD3/anti-CD28 stimulated CD4 Th cells but it did not affect the differentiation of Th1 or Th2 cells. However, IL-2 was increased in BR treated Th2 cells. Considering the above-mentioned results, BR can be applied to a broad range of anti-inflammatory reactions, but our data suggest that it will not be likely to exert any effects on type 1 allergic response.

The roots of Opuntia humifusa (OHR) were extracted with 80% aqueous MeOH and the concentrated extract was partitioned with EtOAc, n-butanol and $H_2O$, successively. The fractions were tested using DPPH and ABST radical scavenging method. The all fractions showed potent scavenging effects. The scavenging effect of the EtOAc fraction was higher than the other fractions, with $IC_{50}$ values as DPPH; $77.0{\pm}1.38{\mu}g/mL$, ABTS: $26.3{\pm}2.02{\mu}g/mL$. And, we investigated anti-inflammatory activities by examining the effects of the OHR fractions on pro-inflammatory cytokine release in the human mast cells (HMC-1). Treatment with OHR fractions clearly reduced the release of the proinflammatory cytokines tumor necrosis factor-alpha (TNF-${\alpha}$), interleukin (IL)-$1{\beta}$, interleukin (IL)-6 and interleukin (IL)-8) in PMACI-stimulated HMC-1 cells. The results showed the potential of OHR as an excellent antioxidant substance and inhibiting inflammatory mediators. Therefore, OHR may be used as a therapeutic approach to various inflammatory diseases.

Soeumin-Googwihyangso-san(SGGHSS) has been used for the prevention or treatment of Soeumin-allergic rhinitis. This study was performed to demonstrate anti-allergic and anti-inflamatory effects of SGGHSS methanol extract in HMC cell lines and activated mouse B cells and CD4+ T cells. SGGHSS inhibited the production of TNF-$\alpha$ in PMA plus A23187 activated HMC-1 cells but not that of IL-6, as measured by ELISA. SGGHSS inhibited the expression of CD23 and surface IgE in B cells as determined by flowcytometry. It also inhibited secretion of IFN-$\gamma$ and IgG1, the Th1 related IgG type, but increased that of IL-4 in anti-CD40 and IL-4 treated B cells as measured by ELISA. As for Th cell differentiation, SGGHSS did not much affect IL-4 or IFN-$\gamma$. Taken together, our data showed that SGGHSS exerted an anti-inflammtory effect by inhibiting TNF-$\alpha$ in mast cells and has anti-allergic activity not via inhibition of CD4+ T cell, but via inhibition of B cells. These results suggest some evidence that SGGHSS can be applied to allergic disease.

Objective : In this study, herbal medicine(GJE, Gardenia jasminoides Ellis; HCT, Houttuynia cordata Thunb.; CIL, Chrysanthemum indicum Linne; PMS,Paeonia moutan Sims, P. subfruticosa Makino; APL, Agrimonia pilosa Ledebour) were screened for their inhibitory activities against Tyrosinase and PMA plus A23187-induced $TNF-{\alpha}$, IL-6, IL-8 productions in HMC-1 cells to reveal their skin -whitening and anti-allergic effect. Method : To investigate Tyrosinase inhibition we treated Mushroom Tyrosinase(Fluka, 93898) $10{\mu}{\ell}$ and 7.5mM Tyrosine (Sigma, T3754) $20{\mu}{\ell}$ with 80% ethanol medicine extracts. Then we observed 96well micro plate extinction at 490nm. In the next experiment, to investigate Anti-allergic effect we blended cultured Human Mast Cells(HMC-1) with medicine extracts. We treated the blended solution with Phorbol 12-myristate 13-acetate(PMA) and A23187, then observed $TNF-{\alpha}$, IL-6, IL-8 by ELISA (enzyme-linked immunosorbent assay) at 450nm. Results : In inhibiting Tyrosinase the results are as follows. 1. We observed 22% inhibition of Mushroom Tyrosinase at $500{\mu}g/m{\ell}$ concentration of GJE extracts. 2. We also could observe that the decreased Mushroom Tyrosinase activities in HCT, CIL extracts. In inhibiing $TNF-{\alpha}$, IL-6, IL-8 productions in HMC-1 cells the results are as follows. 1. Of the extracts examined, HCT, PMS, APL extracts showed over 50% inhibitions of Cytokines at $200{\mu}g/m{\ell}$ concentration. 2. In particular, APL extracts showed the best inhibitory effect on Cytokine productions in a dose-dependent manner. Conclusion : These results suggest that GJE extracts contributes to the anti melanin activities and represent a potential source of whitening agent. Thus these herbal medicines suggest novel drugs on anti-allergic effects.

Objectives: In this study, the pharmacological effects of the ethylacetate extract of Ostericum koreanum(North Kangwhal; NK) on allergic inflammation were investigated in activated human mast cells. Methods: North Kangwhal was extracted with 80% methanol for 24 h, and then fractionated with ethylacetate(NK-EtOAc extract). HMC-1 cells, an human mast line, were pre-incubated with different concentrations of NK-EtOAc extract for 30 min, and then stimulated with PMA(50 nM/ml) and A23187($1{\mu}M/ml$) at indicated times. The cell toxicity was determined by MTT assay. The concentrations of prostaglandin E2(PGE2) and cytokines(TNF-${\alpha}$, IL-8) were measured by enzyme-linked immunosorbant assay. Results: NK-EtOAc extract($10{\sim}50{\mu}g/ml$) significantly inhibited the productions of $PGE_2$, TNF-${\alpha}$ and IL-8 in PMA/A23187-stimulated HMC-1 cells without cell toxicity($0{\sim}50{\mu}g/ml$). NK-EtOAc extract also inhibited PMA/A23187-induced phosphorylation of ERK1/2 MAPK and the NF-${\kappa}B$ p65 subunit translocation into the nuclear of HMC-1 cells. Conclusions: This study suggests that NK-EtOAc extract may have an anti-inflammatory property through suppressing the production of inflammatory mediators in activated mast cells and its molecular mechanism underlies the blocking of NF-${\kappa}B$ pathway.

Immediate-type hypersensitivity is involved in many allergic diseases such as asthma, allergic rhinitis and anaphylaxis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. Stimulation of mast cells releases inflammatory mediators, such as histamine and pro-inflammatory cytokines with immune regulatory properties. We investigated the effect of the aqueous extract of Schizonepeta tenuifolia (AEST) (Labiatae) on the immediate-type allergic reaction. AEST inhibited compound 48/80-induced systemic allergic reaction. AEST attenuated immunoglobulin E (IgE)-mediated skin allergic reaction and histamine release from human mast cell line (HMC-1) cells. In addition, AEST decreased the gene expression and secretion of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-stimulated HMC-1 cells. Our results indicate that AEST inhibits the mast cell-derived allergic reactions and involvement of histamine and pro-inflammatory cytokines in these effects.

Generally, berry fruits have various pharmacological activities such as anti-inflammation, anti-oxidation and anti-cancer effects. The effects of gooseberry, a berry fruits, on atopic dermatitis (AD) have not been widely examined. The aim of this present study is to investigate whether gooseberry modulates AD. We examined the pharmacological effects of gooseberry on 2, 4-dinitrochlorobenzene (DNCB)-induced AD symptoms in mice. To determine the anti-atopic mechanism of gooseberry, we investigated its effects on the production of inflammatory cytokines and activation of nuclear factor-${\kappa}B$ in PMA + ionophore -stimulated human mast cells (HMC-1). The results demonstrated that gooseberry attenuated AD clinical symptoms such as erythema, edema and dryness as well as histamine and IgE serum levels in DNCB-induced AD model mice. Additionally, gooseberry suppressed the expression of inflammatory cytokines and activation of nuclear factor-${\kappa}B$ in stimulated HMC-1. These findings demonstrate that gooseberry is potential agent for treating AD and allergic inflammation.

Objectives : Allergy is an immune dysfunction caused by degranulation from mast cells in the early phase of allergic disease including allergic rhinitis (AR). The purpose of this study was to investigate the effects of Osterici Radix, roots of Ostericum koreanum Maximowicz in human mast cells and experimental allergic animal models. Methods : The anti-allergic effect of Osterici Radix water extract (NK-W) was investigated in human mast cell line, HMC-1 cells, and compound 48/80-induced systemic anaphylactic response in rats and ovalbumin (OVA)-induced AR in mice. Animals were orally administrated with NK-W (10 and 50 mg/kg) or anti-histamine drug, dosodium cromoglycate (50 mg/kg), and then intraperitoneally injected with compound 48/80 (8 mg/kg) or sensitized with 0.1% OVA into nasal. Animals were observed plasma histamine and histological changes of nasal mucosa. Also, mast cell degranulation and histamine production were determined in compound 48/80-stimulated HMC-1 cells. Results : NK-W inhibited compound 48/80-induced degranulation of mast cells and histamine releasing in HMC-1 cells. NK-W decreased mortality and serum histamine releasing in compound 48/80-induced anaphylatic rats in a dose-dependently manner. NK-W also inhibited serum histamine levels in OVA-induced AR mice and improved abnormal histological changes such as expansion of grandular cells and hypertrophy of epithelium in the nasal mucosa. These results indicate that Osterici Radix water extract suppress allergic response through downregulation of mast cell activation. Conclusions : This study suggests that a therapeutic potential of Osterici Radix as a source of anti-allergic agents for use in a number of allergic diseases.

Samultang has been believed for prevention and remedy various blood diseases such as menstrual irregularity, anemia, and metrorrhagia. However, the mechanism that accounts for anti-inflammatory effects of the Samultang is still not fully understood. This study was designed to evaluate whether and how the Samultang could modulate the production of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 treated-human mast cell line, HMC-1. Samultang inhibited the production of tumor necrosis factor $(TNF)-\alpha$, interleukin (IL)-6, granulocyte macrophage colony stimulating factor (GM-CSF), and vascular endothelial growth factor (VEGF) in HMC-1. Maximal inhibition rate of $TNF-\alpha$, IL-6, GM-CSF, and VEGF by 0.1 mg/ml Samultang was about $70.73{\pm}3.0%,\;51.49{\pm}4.14%,\;54.03{\pm}2.09%$, and $47.95{\pm}7.86%$, respectively. Samultang partially blocked PMA plus A23187-induced cyclooxygenase (COX)-2 expression. In addition, Samultang inhibited activation of nuclear factor (NF)-kB, and extracellular signal-regulated kinase (ERK) activation. These results suggest that anti-inflammatory effect of Samulatng may be mediated by the suppression of cytokine production and COX-2 activation via down-regulation of NF-kB and ERK activation.

Objective: Meat quality including muscle color in chickens is an important trait and continuous selective pressures for fast growth and high yield have negatively impacted this trait. This study was conducted to investigate genetic variations responsible for regulating muscle color. Methods: Whole genome re-sequencing analysis using Illumina HiSeq paired end read method was performed with pooled DNA samples isolated from two broiler chicken lines divergently selected for muscle color (high muscle color [HMC] and low muscle color [LMC]) along with their random bred control line (RAN). Sequencing read data was aligned to the chicken reference genome sequence for Red Jungle Fowl (Galgal4) using reference based genome alignment with NGen program of the Lasergene software package. The potential causal single nucleotide polymorphisms (SNPs) showing non-synonymous changes in coding DNA sequence regions were chosen in each line. Bioinformatic analyses to interpret functions of genes retaining SNPs were performed using the ingenuity pathways analysis (IPA). Results: Millions of SNPs were identified and totally 2,884 SNPs (1,307 for HMC and 1,577 for LMC) showing >75% SNP rates could induce non-synonymous mutations in amino acid sequences. Of those, SNPs showing over 10 read depths yielded 15 more reliable SNPs including 1 for HMC and 14 for LMC. The IPA analyses suggested that meat color in chickens appeared to be associated with chromosomal DNA stability, the functions of ubiquitylation (UBC) and quality and quantity of various subtypes of collagens. Conclusion: In this study, various potential genetic markers showing amino acid changes were identified in differential meat color lines, that can be used for further animal selection strategy.
