Objectives : We investigated genetic toxicity of HMCO5 using the Micronucleus Test in bone marrow cells of mice and Bacterial Reverse Mutation Assay in plate incorporation method according to OECD Guidelines and KFDA Guidelines. Methods : 1. Micronucleus test: The male rats were divided into 5 groups, respectively; G(1), treated with distilled water: G(2), treated with 1250mg/kg HMC05: G(3), treated with 2500mg/kg HMC05, G(4), treated with 5,000mg/kg HMC05; G(5), treated with Cyclophosphamide $H_2O$. Sterilized distilled water and HMC05 were administered for two consecutive days. Cyclophosphamide $H_2O$ was administered once on the day of 2nd administration. 2. Bacterial Reverse Mutation Aassay: Experimental groups were divided into two groups: with S-9mix(+S) or without S-9mix(-S). Each group treated with sterilized distilled water only, HMCO5(62, 185, 556, 1,667, $5,000{\mu}g$/plate) and, positive vehicles(Sodium azide, 2-Aminoanthracene, 4-Nitroquinoline N-oxide, ICR 191), respectively. Results : HMC05 did not show any changes in the number of micronucleated polychromatic erythrocytes(MNPCE) among 200 polychromatic erythrocytes compare to negative control. However, there were significant (p<0.01) increase with CPA in MNPCE. In Bacterial Reverse Mutation Aassay, no significant increases in the number of revertant colonies compared to (삭제) negative control were detected in all concentrations of HMC05. Conclusions : These results indicate that HMC05 did not show any genotoxicity against in Micronucleus test and Bacterial Reverse Mutation Aassay.

Objectives: HMCO5 is an extract obtained from 8 different herbal mixtures. We undertook a safety evaluation of HMCO5 for a dose range finding (DRF) toxicity test in specific pathogen free (SPF) Sprague-Dawley (SD) male and female rats. Methods: The male and female rats were divided into 4 groups, respectively; G(0), treated with distilled water: G(1), treated with 222 mg/kg HMC05: G(2), treated with 667 mg/kg HMC05, and G(3), treated with 2,000 mg/kg HMC05; HMC05 was administered orally for 4 weeks. The safety evaluation examined clinical signs, mortality, body weight, food consumption, water consumption, ophthalmic findings, urinalysis, hematological values, absolute & relative organ weights, and necropsy findings during the tests. Results: There were no changes in clinical signs, mortality, body weight, food consumption, water consumption, and ophthalmic findings examined during the test periods. In serum biochemical values, triglyceride was increased in male group G(3) and Na$^+$ decreased significantly in male groups G(2), G(3) and G(4). In male group G(4), spleen weight decreased relatively and increases of absolute & relative left ovary weights were found. In addition, an adhesion of liver to diaphragm was found in male group G(2). However, we could not find any dose-interrelationships in these changes. Conclusions: These results indicate that HMC05 extract did not show any toxicity in the DRF toxicity study. Therefore, it suggests that establishment of 1,000, 333 and 111 mg/kg dosages are moderate in a repeated dose 26-week oral toxicity study of HMC05.

Objectives : Allergy is an immune dysfunction caused by degranulation from mast cells in the early phase of allergic disease. The purpose of this study was to investigate the anti-allergic effect of fermented Angelicae gigantis Radix in human mast cell line, HMC-1. Method : The Angelicae gigantis Radix was fermented by Lactobacillus acidophilus. The cell toxicity of fermented Angelicae gigantis Radix(FAGR) was determined by MTT assay. The release of ${\beta}$-hexosaminidase from HMC-1 stimulated by phorbol-12-myristate 13-acetate (PMA) plus A23187 was determined by ${\beta}$-hexosaminidase assay. Also, the concentrations of cytokines (interleukin-$1{\beta}$, -6, -8 and tumor necrosis factor-alpha) were measured by enzyme-linked immunosorbent assay. The gene expression of COX-2 from HMC-1 stimulated by phorbol-12-myristate 13-acetate (PMA) plus A23187 was determined by reverse transcription polymerase chain reaction. The release of histamine on substance P-stimulated HMC-1 was measured by histamine assay. Result : The FAGR suppressed the release of ${\beta}$-hexosaminidase, a marker of degranulation, from HMC-1 stimulated by PMA plus A23187. The FAGR inhibited the production of interleukin-$1{\beta}$, -6, -8 and tumor necrosis factor-alpha. The FAGR inhibited the expression of COX-2 mRNA. The FAGR suppressed the release of histamine on substance P-stimulated HMC-1. Conclusion : These results provide that FAGR may be beneficial in the treatment of allergic inflammatory disease.

${\beta}$-sitosterol glucoside exists in a variety of plants and have anti-tumor, anti-microbial, and immunomodulatory activities. Mast cells and eosinophils play important roles in a variety of inflammatory diseases, specifically asthma and atopic dermatitis. In the present study, we used lactose-${\beta}$-sitosterol (L-BS) and investigated the effect of L-BS on inflammatory responses of the human mast cell line, HMC-1 and the human eosinophilic leukemia cell line, EoL-1. In HMC-1 cells, L-BS significantly inhibited cell migration in response to stem cell factor without cytotoxicity. However, the mRNA expression of CC chemokine receptors (CCRs), including CCR1-5, were not altered after L-BS treatment in HMC-1 cells. LPS-induced IL-4 production was also suppressed by L-BS in a dose-dependent manner. In EoL-1 cells, the concentration ranging from 0.1 ${\mu}M$ to 10 ${\mu}M$ of L-BS had no cytotoxicity and had no effect on mRNA expression of major protein-mediators derived from activated eosinophils. However, 100 ${\mu}M$ of L-BS induced the apoptosis of EoL-1 cells in a time-dependent manner. This finding indicates the possibility of L-BS as a potential therapeutic molecule in inflammatory diseases and may contribute to the need to improve current therapeutic drugs.

Diesel particulate matter (DPM) induces inflammatory cytokines in HaCaT and stimulates XRE promoter activity through AhR binding. Thus, it increases CYP gene family expression. In this study, we have elucidated inhibitory effect of LG Herbal Medicine Complex (LG-HMC) on DPM-induced XRE promoter activity and inflammatory cytokine expression. First of all, the XRE promoter activity was overexpressed by DPM treatment and the LG-HMC abrogated the XRE promoter activity. Morus alba bark extract, Scutellaria baicalensis root extract and constituents of LG-HMC, were found to be main effecters against DPM induced XRE promoter activation. We also found that DPM treatment elevated inflammatory cytokines in HaCaT and the treatment of LG-HMC, Morus alba bark extract and Scutellaria baicalensis root extract down-regulated the DPM induced inflammatory cytokine expression. Additionally, Morus alba bark extract and Scutellaria baicalensis root extract were found to act as free radical scavengers. In conclusion, we confirmed skin protective effect of LG-HMC and uncovered two components, Morus alba bark extract and Scutellaria baicalensis root extract, that play major role in protecting epidermal kertinocytes from damage.

'SecSec' has been used for the purpose of prevention and treatment of throat diseases such as sore throat, cough, bronchial asthma and allergic asthma in Korea. However, its effect in experimental models remains unknown. To investigate the biological effect of SecSec, we examined cytotoxicity and secretion of inflammatory cytokines on human leukemic mast cell line, HMC-1, stimulated with phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. SecSec by itself had no cytotoxicity on HMC-1. When SecSec (1 mg/ml) was added, the secretion of tumor necrosis factor-alpha $(TNF-{\alpha})$, interleukin (IL)-6, and granulocyte macrophage-colony stimulating factor (GM-CSF) was significantly inhibited about 47.20%, 25.55%, and 46.43%, respectively on PMA plus A23187-stimulated HMC-1 cells. But SecSec did not inhibit IL-8 secretion. These findings may help understanding the mechanism of action of this medicine leading to control activated mast cells on allergic inflammatory condition like asthma.

Cheonggeumganghwa-tang(CGT) has been used for the purpose of prevention and treatment of bronchial asthma and allergic asthma in Korea. To investigate the biological effect of CGT, the author examined cytotoxicity and inflammatory cytokines secretion with human mast cell line, HMC-1. HMC-1 was stimulated with phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. CGT by itself had no effect on viability of HMC-1. The effects of CGT on the secretion of tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-6 from HMC-1 were evaluated with enzyme-linked immunosorbent assay (ELISA). CGT (1 ㎎/㎖) inhibited PMA plus A23187 -induced TNF-α and IL-6 secretion, by 93.86 ± 2.05%, 68.69 ± 2.86%, respectively. CGT also inhibited the NF-κB (p50) expression. Taken together, these results suggest that CGT inhibit the production of inflammatory cytokines in HMC-1 cells through blockade of NF-κB activation.

Objectives : On an experimental basis, the effects of atopic dermatitis induced materials on the expression of cytokine genes in human monocytes (THP-1, U937) and mast cells were studied. This study was carried out to be considered a fundamental knowledge in the research on the good of oriental medicine. Methods : After culturing THP-1, U937, and HMC-1, with the three different concentrations of LPS ($1\;{\mu}g/ml$), DPE ($10\;{\mu}g/ml$), and DNCB ($1\;{\mu}g/ml$), atopic dermatitis induced materials were treated in the culture medium. To investigate cytokine genes expression patterns, with lysis buffer and separation reagent, total RNA was extracted from THP-1, U937, and HMC-1 at intervals of 0, 12, 24, and 48 hours. Both cytokine mRNA expression patterns by atopic dermatitis induced materials and change of cytokine genes expression patterns in relation to atopy by selenium were analyzed with RT-PCR. Also IL-4 and INF-$\gamma$, which were secreted in the HMC-1, were analyzed using ELISA method. Results : 1. After treating THP-1 and U937 with LPS, DPE, and DNCB, there was no significant change in cytokine genes themselves, but various cytokines (IL-4, IL-6, IL-8, IL-13, IFN-$\gamma$, IFN-a, MCP-1, B2-MG) were expressed. 2. In the case of HMC-1, the expressions of IL-6 and IL-8 were significantly increased in the analysis of mRNA expression by dust mite allergens in DPE. 3. As a result of ELISA method, it is certain that IL-4 and IFN-$\gamma$ protein were secreted in the HMC-1 by DPE. 4. Selenium, an essential trace element, decreased the IL-10 and IL-13 expression in the HMC-1 by DPE. Conclusion : The results suggest that it is necessary to choose proper atopic dermatitis induced materials and suitable cultured cells in establishment of in vitro model of atopic dermatitis.

Cyanidin 3 - rutinoside chloride (CRC) is major anthocyanin, found in Schisandra chinensis, is known to have antioxidant, anticancer, anti-inflammatory, tonic, and anti-aging effects in Korea, China and Japan. In the present study, the human mast cell line (HMC-1) was used to investigate the effects on the production of pro-inflammatory mediators. In this study, CRC showed no cytotoxicity in HMC-1. CRC significantly inhibited the secretion of inflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-6 in PMA plus A23187 cacium ionophore (PMACI)-stimulated HMC-1 cells. In addition, CRC suppressed the serum levels of IgE. Furthermore, CRC decreased the PMACI- stimulated phosphorylation of mitogen activated protein kinases (MAPKs) such as p-ERK, p- JNK and p-P38. These results indicate that the pharmacological actions of CRC suggest their potential activity for treatment of allergic inflammation through the down-regulation of mast cell activation.
