  • Objectives : The purpose of this study is to investigate the effect of Gupoongjeseuptang (GPJST) on atopic dermatitis by in vivo experiment using NC/Nga atopic dermatitis mouse, which has histological and clinical similarities to the atopic dermatitis of human. Methods : To investigate the effect of GPJST on atopic dermatifis, we evaluated atopic dermatitis-like skin lesions by clinical skin index and analyzed immunological parameters in peripheral blood mononuclear cells (PBMCs), splenocytes, draining lymph node (DLN) and performed skin histology in ears and dorsal skin of atopic dermatitis-like skin NC/Nga mouse in vivo. Results : In vivo, clinical skin severity score were significantly lower in GPJST group than control group. IgE, IL-6, $TNF-{\alpha}$, IgG1, IgM, IgG2a and IgG2b levels in serum decreased remarkably in GPJST group than control group. Also, total absolute number of $CD3^+CD69^+$, and $CCR3^+$ cells recovered as normal in PBMCs and $CD3^+$, $CD3^+CD69^+$ decreased significantly compared with control group in isolated DLN from NC/Nga mouse and total absolute number of $CD11b^+Gr-1^+$, $CCR3^+CD3^+$ in dorsal skin of NC/Nga mouse decreased by GPJST. We analyzed ear and neck-back skin after biopsy and dyeing by hematoxyline/eosin (H&E) and toluidine staining (mast cells marker) and obtained results that GPJST are very effective to histological symptoms (dermal and epidermal thickening, hyperkeratosis and inflammatory cell (CD4, $CCR3^+$) infiltration). Conclusions : This study demonstrates immunological activity of GPJST on atopic dermatitis-like model mice.

  • Although the effect of Bee Venom has been reported, its mechanism has not been fully elucidated. Nitric Oxide(NO) is one of the free radicals and mediates in inflammation diseases. Chemokines contribute to the pathogenesis of several disorders such as allergic rhinitis and rheumatoid arthritis and so on. The objective of this study was to investigate the scavenging effect of Bee Venom on NO and on expression of chemokine genes. There was no significant NO scavenging effect in Crude Bee Venom, Apamin, Melittin, and MCD-peptide. The expression of chemokines was examined by RT-PCR using the human mast cell line(HMC-1), which is known to secrete and express chemokines. In order to investigate the protective effect of Bee Venom, HMC-1 cells were incubated with pretreatment of Bee Venom for 24 hrs and stimulated with 1 uM calcium ionophore A23178 for 2 hrs. RT-PCR analyses of chemokine genes showed that expressions of RANTES and MCP-1 were increased compared to the calcium ionophore-only treated group. But IL-8 and MCP-3 did not express increasing effect compared to control group. This study may provide important basic data on the possibility of the clinical treatment of Bee Venom in inflammation diseases.

  • Mycobacterium celatum is a recently described nontuberculous mycobacterium. Even though pulmonary or lymphatic infection cases were reported previously in human, the clinical significance of the infection with M. celatum is not yet understood completely. Mast infections with this species occurred in the patients with suppressed cell-mediated immunity such as AIDS, and there are only a few cases of pulmonary infection with M. celatum in immunocompetent adults or infants in the world. In Korea, mycobacterial pulmonary infection is a major problem of respiratory disease but, there has been no pulmonary infection with M. celatum reported. We report, to our knowledge, the first Korean case of pulmonary infection with M. celatum, which was identified by rpoB genomic sequencing.

  • Objective : KagamJwagwiEum(KJE) has been used for the purpose of prevention and treatment of bronchial asthma and allergic asthma in Korea. To investigate the biological effect of KJE, the author examined cytotoxicity and inflammatory cytokines secretion with human leukemic mast cell line, HMC-1. Methods: HMC-1 was stimulated with phorbol 12-myristate 13-acetate(PMA) and calcium ionophore A23187. KJE by itself had no effect on viability of HMC-l. The effects of KJE on the secretion of tumor necrosis $factor-alpha(TNF-{\alpha})$, interleukin(IL)-6 and IL-8 from HMC-1 were evaluated with enzyme-linked immunosorbent assay. Results : KJE inhibited PMA plus A23187-induced $TNF-{\alpha}$ and IL-6 secretion. But KJE had no effect IL-8 secretion: KJE had immunoregulatory effects on cytokines, increased secretion of NO and $TNF-{\alpha}$ but did not effect IL-12 secretion when the cells were primed and trigged with $IFN-{\gamma}$ in the peritoneal macrophages of C57BL/6 mice. Conclusions : Taken together, these results suggest that KJE inhibit the production of inflammatory cytokines in HMC-1 cells and activate macrophages.

  • Goat milk is highly nutritious and is consumed in many countries, but the development of functional foods from goat milk has been slow compared to that for other types of milk. The aim of this study was to develop a goat milk protein hydrolysate (GMPH) with enhanced digestibility and better hypoallergenic properties in comparison with other protein sources such as ovalbumin and soy protein. Goat milk protein was digested with four commercial food-grade proteases (separately) under various conditions to achieve the best hydrolysis of αs -casein and β-lactoglobulin. It was shown that treatment with alcalase (0.4%, 60℃ for 30 min) effectively degraded these two proteins, as determined by SDS-PAGE, measurement of nonprotein nitrogen content, and reverse-phase high-performance liquid chromatography. Hydrolysis with alcalase resulted in a significant decrease in β-lactoglobulin concentration (almost to nil) and a ~40% reduction in the level of αs-casein. Quantification of histamine and TNF-α released from HMC-1 cells (human mast cell line) showed that the GMPH did not induce an allergic response when compared to the control. Hence, the GMPH may be useful for development of novel foods for infants, the elderly, and convalescent patients, to replace cow milk.

  • Perilla frutescens var. acuta Kudo (PF) is a traditional Korean medicinal herb for allergic reaction regulation. In the present study, we investigated the effect of 30% ethanol extract powder of PF (EPPF) and rosmarinic acid (RA), the active compound of EPPF on various allergic reactions using in vivo and in vitro models. EPPF and RA significantly inhibited compound 48/48-induced systemic anaphylactic reaction and histamine release (P < 0.05). In addition, EPPF and RA significantly inhibited passive cutaneous anaphylaxis (PCA) in a dose-dependent manner (P < 0.05). These effects were stronger than those of disodium cromoglycate, the reference drug tested. EPPF and RA also significantly inhibited production of inflammatory cytokines, tumor necrosis factor-a interleukin (IL)-6, and vascular endothelial growth factor on the PCA reaction and phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated human mast cell line, HMC-1 cells (P < 0.05). Moreover, EPPF and RA showed an inhibitory effect on lipopolysaccharide (LPS)-induced IL-4 production from whole spleen cells. Finally, EPPF and RA significantly decreased IL-4-dependent IgE production by LPS-stimulated whole spleen cells (P < 0.05). In conclusion, these results indicate that EPPF has potent anti-allergic activities.

  • Bibimbab (mixed rice) is a traditional Korean one-dish meal. This study was carried out to investigate the anti-inflammatory and antioxidative effects of raw and seasoned ingredients used in Bibimbab (Cucurbita moschata P., Platycodon grandiflorum A., Vigna radiata L., Porphyra yezonensis udea, Allium ampeloprasum L., Pterdium aguilinum, Raphanus sativus). Human mast cells (HMC-1) were pretreated with 70% ethanol extracts of Bibimbab and further cultured for an appropriate time after the addition of phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. Cell viability was determined by an MTT assay. None of the ingredients showed cytotoxic effects at a concentration of 1.0 ${\mu}g/ml$. Anti-inflammatory effects were analyzed at 0.01, 0.1, and 1.0 mg/ml concentrations of the raw, seasoned ingredients of PMA. A23187 stimulated HMC-1. Among the various ingredients, seasoned A. ampeloprasum L. extract showed the highest inhibition of TNF-${\alpha}$ and IL-6 secretion (90% and 93%, respectively) at a concentration of 1.0 mg/ml. The R. sativus extract showed the highest inhibition (85%) of IL-8 secretion. DPPH analysis of the antioxidation properties of the ingredients showed that raw and seasoned A. ampeloprasum extracts exhibited the highest DPPH free radical scavenging activity (67.50 and 73.65%, respectively). These results suggest that seasoned ingredients used in Bibimbab have lower anti-inflammatory effects in relation to TNF-${\alpha}$ and IL-6 secretion than raw ingredients in PMA- and A23187-treated HMC-1. In addition, the seasoned ingredients showed a tendency to increase antioxidative activity. Therefore, the ingredients used in Bibimbab have potential as anti-inflammatory and antioxidation agents.

It resulted that total absolute number of $CD3^+$, $CD19^+$, $CD4^+$ and $CD8^+$ cells were recovered as normal and $CD3^+$$CD69^+$ were decreased significantly compared with control group in isolated DLN and PBMCs from NC/Nga mouse and total absolute number of $Gr-1^+$, $CD11b^+$ and $CD3^+$ in dorsal skin of NC/Nga mouse were decreased by JWTG. We analyzed ear, DLN, and neck-back skin after biopsy and dyeing by hematoxyline/eosin(H&E) and toluidine staining (mast cells marker) and obtained results that JWTG were effective to histological symptoms (dermal and epidermal thickening, hyperkeratosis and inflammatory cell infiltration). Ear thickness was decreased significantly than the control group and the size of inflammatory lymphocytes cells(ILC) and plasma cells(PC) in DLN were also decreased.

  • In our previous study, a new herbal preparation (HemoHIM) was developed as a functional food for the radioprotection and immunomodulatory agents. In order elucidate the mechanism involved, we examined the effect of HemoHIM on the compound 48/80-induced histamine release, and on the phorbol 12-myristate 13-acetate (PMA)/calcium ionophore (A23187)-induced inflammatory cytokine secretion in HMC-1. The cell culture supernatants were harvested, and the cytokines (IL-4, IL-6, IL-8, TNF-$\alpha$, GM-CSF) in the supernatants were measured by enzyme-linked immunosorbent assay. The total RNA of the cells was extracted, and the cytokines or c-kit/tryptase/Fc$\varepsilon$RI's messenger RNA expressions were examined using reverse transcriptase polymerase chain reaction. Under low concentrations, HemoHIM inhibited histamine release in HMC-1 stimulated compound 48/80. Furthermore HemoHIM inhibited PMA/A23187-induced inflammatory cytokines' secreation or mRNA expression in a dose-dependent manner. But IL-8 secretion was not inhibited by low concentrayion of HemoHIM, respectively. The mRNA expression of c-kit and Fc$\varepsilon$RI were also inhibited in a dose-dependent manner. Tryptase mRNA expression was only inhibited by low concentration of HemoHIM. These results indicated that HemoHIM might be an useful agent for protection against allergy as well as immune modulation, especially since it is a relatively nontoxic natural product.
