  • Objectives PRAL (Prunus armniaca Linne Var) is a herbal formula in Oriental Medicine, known for its anti-inflammatory and anti-allergenic properties. However, its mechanism of action and the cellular targets have not yet been found enough. The purpose of this study is to investigate the effects of PRAL on Th2 cytokines expression in MC/9 mast cells. Methods The effect of PRAL was analyzed by ELISA, Real-time PCR, Western blot in MC/9 mast cells. mRNA levels of GM-CSF, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ were analyzed with Real-time PCR. Levels of IL-13, MIP-$1{\alpha}$ were measured using enzyme-linked immunosorbent assays (ELISA). NFAT, AP-1 and NF-${\kappa}B$ p65 were examined by Western blot analysis. Results PRAL inhibited GM-CSF, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ mRNA expression in a dose dependent manner. GM-CSF, IL-4, IL-5 mRNA expression were inhibited significantly in comparison to DNP-IgE control group at concentration of 100 ${\mu}g/ml$ and IL-6, IL-13, TNF-${\alpha}$ mRNA expression were inhibited at concentration of 50 ${\mu}g/ml$, 100 ${\mu}g/ml$. PRAL also inhibited the IL-13, MIP-$1{\alpha}$ production significantly in comparison to DNP-IgE control group in a dose dependent manner. IL-13 production was inhibited at a concentration of 200 ${\mu}g/ml$, 400 ${\mu}g/ml$ and MIP-$1{\alpha}$ was inhibited at a concentration of 100 ${\mu}g/ml$, 200 ${\mu}g/ml$, 400 ${\mu}g/ml$. Western blot analysis of transcription factors involving Th2 cytokines expression revealed prominent decrease of the mast cell specific transcription factors including NFAT-1, c-Jun as well as NF-${\kappa}B$ p65 but not NFAT-2 and c-Fos. Conclusion These results indicate that PRAL has the effect of suppressing Th2 cytokines production in the MC/9 mast cells. These data represent that PRAL potentiates therapeutic activities to the allergic disease by regulating Th2 cytokines in the MC/9 mast cells.

  • Sea Buckthorn (Hippophae rhamnoides L.) has been used in traditional medicine for the treatment of cough, indigestion, circulatory problems and pain. The associated anti-inflammatory effect of this agent is achieved via the inhibition of Nf-${\kappa}B$ signaling, a property that has been demonstrated to effectively control the symptoms of various skin disorders, including atopic dermatitis. Accordingly, the purpose of this study was to assess the efficacy of Sea Buckthorn in reducing the production of lipopolysaccharide (LPS) activated nitric oxide (NO) by inhibiting the Nf-${\kappa}B$ pathway, as measured by the symptoms of atopic dermatitis (AD) occurring secondarily to inflammation and immune dysregulation. Our data demonstrate that Sea Buckthorn significantly decreased the LPS-induced production of NO (p<0.001). Atopic dermatitis was induced by repeated application of 2,4-dinitrochlorobenzene to the dorsal skin of mice. Topical application of 5% Sea Buckthorn extract improved the symptoms of AD, specifically reducing disease severity scores, scratching behaviors and epidermal thickness. When compared to the control group, animals treated with Sea Buckthorn exhibited increased serum IL-12 levels and decreased serum TNF-${\alpha}$, IL-4 and IL-5 levels. Such a modulation of biphasic T-helper (Th)1/Th2 cytokines may result in a reduction in serum IgE levels. Our findings suggest that mechanism of action of Sea Buckthorn in the treatment of AD is associated with a marked anti-inflammatory effect as well as an inhibition of Th2-mediated IgE overproduction via the modulation of biphasic Th1/Th2 cytokines. Such results suggest that topical Sea Buckthorn extract may prove to be a novel therapy for AD symptoms with few side effects.

  • We investigated the effect of Sungmagalkun-tang (SGT) on the allergy. We conformed compound 48/80-induced active systemic anaphylatic shock, anti-dinitrophenyl IgE-mediated passive cutaneous anaphylaxis and ovalbumin-induced anaphylatic shock. Also observed IL-4 and GM-CSF mRNA expression in ovalbumin-induced allergic lung tissue and RBL-2H3. Histamine release is measured in RBL-2H3. SGT inhibited active systemic anaphylatic shock, passive cutaneous anaphylaxis and ovalbumin-induced anaphylatic shock by oral administration. We observed that SGT was concentration-dependently reduced IL-4 and GM-CSF mRNA expression in ovalbumin-induced allergic lung tissue and RBL-2H3 by SGT. In addition, SGT reduced histamine release in RBL-2H3. These results indicate that SGT has anti-histamic effect and controls IL-4 and GM-CSF mRNA expression on allergy.

  • Economic animal husbandry workers exposed to organic dust can be suffered from immunologic disorders. Our study was to determine immunological parameters related with occurrence of respiratory allergic diseases to animal husbandry workers in Korea for the first time. Peripheral blood were obtained from twenty-five pig barn workers, forty-nine chicken farming workers and fifty-one non-agricultural control workers. Significantly upregulated plasma IgE level was observed with pig-barn workers than that of chicken farming workers or healthy community control subjects. Furthermore, level of histamine, a hallmark of allergy induction, was upregulated in the pig and chicken farming workers in comparison with that of the control subjects. Downregulation of $IFN_\gamma$ and $TNF_{\alpha}$ production from T cells was apparent in the animal husbandry workers compared with the control subjects. Meanwhile, T cells collected from the pig barn workers demonstrated significantly higher production of IL-4 and IL-10 than the other groups. There were also alterations in IgG subclass distribution. In conclusion, immunological modulation probably leading to occupational allergic diseases can be occurred in the economic animal husbandry workers and the pig barn workers could be the most risky group to the work-related allergic disease.

  • Broussonetia kazinoki Siebold. (B. kazinoki) has long been used in the manufacture of paper in Asian countries. Although B. kazinoki leaves (BK) have been employed in dermatological therapy, use of BK has not been tested in patients with atopic dermatitis (AD). Using Nc/Nga mice, which are genetically predisposed to develop AD-like skin lesions, we confirmed the efficacy of BK in AD treatment. BK extract was applied topically to Dermatophagoides farinae-induced AD-like lesions in Nc/Nga mice, and the effects were assessed both clinically and by measuring skin thickness on the back and ears. We measured the effects of BK extract on plasma levels of IgE and IL-4. We also measured the ability of BK extract to inhibit the secretion of hTARC in HaCaT cells after stimulation by TNF-${\alpha}$ and IFN-${\gamma}$. We found that BK extract significantly reduced ear and dorsal skin thickness and the clinical signs of AD, as well as significantly down-regulating the plasma levels of IgE and IL-4 (p<0.01 for each comparison). Moreover, $500{\mu}g/mL$ of BK extract inhibited hTARC secretion in HaCaT cells by activated TNF-${\alpha}$/IFN-${\gamma}$ by about 87%. These findings suggest that topical application of BK extract has excellent potential in the treatment of AD.

  • 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.

  • Objectives & Methods : The purpose of this study is to observe the effects of Coicis Semen Herbal-acupuncture solution (CS-HAS) at the Joksamni (ST36) on the collagen-induced arthritis in the DBA/1J mouse. The author performed several experiments to analyze the effects of CS-HAS on arthritis; change of the weight; the spleen size and adhesion rate; serum cytokine levels; serum antibody levels; changes of immunocyte counts; the histological changes of joint. Results : In the Coicis Semen Herbal-acupuncture (CS-HA), arthritis index, the incidence of arthritis, and the degree of joint edema were decreased. In CS-HA, there was no weight loss. The size of the spleen, adhesion rate, and the edema and transformation of joint were lowered. In CS-HA, the levels of IL-1${\beta}$, IL-6, TNF-${\alpha}$, IFN-${\gamma}$, IgG, IgM, and anti-collagen II in serum and the levels of IFN-${\gamma}$, IL-4, IL-10 in spleen were significantly decreased. In CS-HA, the expression ratios of $CD45^+$ to $CD3e^+$ and $CD8^+$ to $CD4^+$ were decreased. Also, the overall $CD4^+/CD8^+$ cell ratio was lowered in spleen. Ratios of the $CD4^+/CD25^+$, $CD45^+/CD69^+$ cells were decreased in lymph nodes. In addition, ratios of the $CD3^+/CD69^+$, $CD11b^+/Gr-1^+$ cells were also decreased in synovium. In the histological study, the cartilage destruction and synovial cell proliferation, and collagen fiber destruction were decreased with CS-HA treated group. Conclusions : From the results mentioned above, it is suggested that CS-HA at the ST36 has several significant effects on the collagen-induced arthritis.
