  • Dojuk-San is known to be effective for treating a urinary diseases and stomatitis. However, its effects on the bone marrow-derived mast cell(BMMC) mediated allergy and inflammation mechanism remain unknown. In this study, the biological effects of Dojuk-San ethanol extract(DJS) were evaluated while focusing on its effects on the allergic mediator in phorbol 12-myristate 13-acetate(PMA) plus calcium ionophore A23187(A23187)-stimulated BMMCs. An investigation was also conducted to determine its effects on the production of several allergic mediators including interleukin-6(IL-6), prostaglandin D2($PGD_2$), leukotrieneC4(LTC4) and ${\beta}$-Hexosaminidase(${\beta}$-Hex). The results revealed that DJS inhibited the PMA plus A23187 induced production of IL-6, PGD2, LTC4 and ${\beta}$-Hex. Taken together, these findings indicate that DJS has the potential using in the treatment of allergy.

  • In this study, the inhibitory activities of fifty plant extracts on IgE-mediated degranulation in the rat basophilic leukemia cell line (RBL-2H3 cells) were measured; the release of interleukin (IL)-4 and β-hexosaminidase from IgE-sensitized cells treated with the plant extracts was measured; and the effects of the plant extracts on cell viability were tested. The results of the analysis of plant extracts at 20 μg/ml, including the aerial part of Magnolia sieboldii K. Koch, exhibited suppressive activities upon the release of IL-4. Furthermore, several plant extracts including methanol extracted from Lindera erythrocarpa Makino (aerial part) at the same concentration significantly inhibited the release of β-hexosaminidase. Twenty-six of the plant extracts, including methanol extract of Weigela subsessilis (Nakai) L. H. Bailey (branch), showed a cell proliferation effect of over 80% at 100 μg/ml. In conclusion, the results suggest that the leaf/stem of Geum japonicum Thunb. and the stamen/ovary of Nelumbo nucifera Gaertn., which exhibited effective inhibition on β-hexosaminidase release and IL-4 release from mast cells and showed high cell viability, could be useful candidates as anti-allergy materials.

  • Egg allergy has been reported as the most prevalent food hypersensitivity among children. One of the major egg allergens is ovalbumin (OVA). OVA is the major protein in the egg white, comprising 54% of its total protein content. Curcumin isolated from Curcuma longa has been used as folk remedies in order to treat many chronic diseases for many years. In the present report, we present biochemical evidence that curcumin inhibits the NF-${\kappa}B$ activation induced by OVA. Curcumin also inhibits OVA-induced iNOS expression and nitrite production. These data suggest new approaches for the development of efficient anti-allergic strategies.

  • Bangpungtongseong-san(BPTSS, Fangfengtongsheng-san in Chineses) is a traditional herbal formula comprising 18 medicinal herbs. In the present study, we performed the simultaneous analysis for four compounds of BPTSS and examined anti-allergic effects in human keratinocytes and mouse splenocytes. The column for separation of four compounds was used Luna C18 column and maintained at 40℃. The mobile phase for gradient elution consisted of two solvent systems. The analysis was carried out at a flow rate of 1.0 mL/min with PDA detection at 254 and 280 nm. To evaluate production and expression of Th2 chemokines, ELISA and RT-PCR were conducted in tumor necrosis factor (TNF)-α and interferon (IFN)-γ-stimulated HaCaT cells with or without BPTSS or silymarin, a positive control for skin inflammation. To measure Th2 cytokines, primary mouse splenocytes were treated with BPTSS and performed ELISA for interleukin (IL)-4, 5, 13. Calibration curves were acquired with r2>0.9999. The contents of geniposide, liquiritin, baicalin, and glycyrrhizin in BPTSS were 5.06 ㎎/g, 7.33 ㎎/g, 27.56 ㎎/g, and 7.81 ㎎/g, respectively. BPTSS reduced TARC and RANTES production and mRNA expression in TNF-α and IFN-γ-treated HaCaT cells. BPTSS inhibited IL-4, 5, and 13 production in mouse splenocytes. Our data will be a helpful information to upgrade quality control and anti-allergic effects of BPTSS.

  • Objective : Benign prostatic hyperplasia(BPH) is one of the most common diseased among elderly men. BPH can be treated with alpha-1 adrenergic blocker or $5{\alpha}$-reductase inhibitor(Finasteride) that reduces serum dihydrotestosterone(DHT). Phellodendri Cortex Ex has been broad studied on its chemical components, pharmacological activity, and clinical effects on anti-inflammation, anti-allergy, anti-tumor, immunity, antibacteria and other bioactivities. In this study, we investigated the therapeutic effects and action mechanism of Phellodendri Cortex Ex with a BPH induced by castration and testosterone treatment. Methods : Sprague-Dawley rats were treated with testosterone after castration for induction of experimental benign prostatic hyperplasia, which is similar to human benign prostatic hyperplasia in histopathological profiles. Phellodendri Cortex as an experimental specimen, and Finasteride as a positive control, were administered orally. The prostates were evaluated by histopathological changes, and the expression of $5{\alpha}$-reductase genes. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with Phellodendri Cortex Ex showed a diminished range of the tissue damage. In the reverse transcription-polymerase chain reaction(RT-PCR) of $5{\alpha}$-reductase genes, Phellodendri Cortex inhibited the expression of $5{\alpha}$-reductase genes. Conclusions : These findings suggest that Phellodendri Cortex Ex may protect the glandular epithelial cells and also inhibit stromal proliferation in association with the suppression of $5{\alpha}$-reductase. From these results, we suggest that Phellodendri Cortex Ex could be a useful agent for treating the benign prostatic hyperplasia.

  • $CheongGiGeoYangTang$ has been used for anti-allergenic purpose. However there was no experimental study about its effect. Therefore, this study was designed to investigate the anti-allergenic effect of $CheongGiGeoYangTang$. Methods Modifiability of RBL-2H3 mast cells' IL-4, IL-13 was analyzed by qRT-PCR and ELISA. Also, the suppressive effect of GATA-1, GATA-2, NF-AT1, NF-AT2, AP-1 and NF-${\kappa}B$ p65 transcription factors was observed by western blotting. OVA-specific IgE, IL-4 and IL-13 production in ovalbumin allergy model was examined as well. Results It was showed that the RBL-2H3 mast cells treated with $CheongGiGeoYangTang$ extract(CGGYT) was significantly suppressed mRNA expression, production of IL-4 and IL-13, and prominently inhibited the expression of transcription factors including GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos and NF-${\kappa}B$ p65 but not c-Jun. The administration of CGGYT was suppressed the amount of OVA-specific IgE, IL-4 and IL-13 in OVA/alum-sensitized mice. Conclusions We considered CGGYT would regulate the allergic inflammation as inhibition of IL-4 and IL-13 production in activated mast cells and Th2 cells.

  • The purpose of this study was to investigate Anti-allergic Inflammatory Effects of Hwangyounhaedog-tang on PMA plus A23187-stimulated RBL-2H3 cells. We examined MTT assay, ${\beta}$-hexosaminidase activity, IL-4 and TNF-${\alpha}$ from RBL-2H3 after pre-treatment with HHT. In addition, we investigated expression of COX-1 and COX-2 mRNA using RT-PCR study. The results are as follows: All the concentrations of HHT from 1 to 4 mg/ml didn't have an effect on cell viability. In RBL-2H3 cells, ${\beta}$-hexosaminidase release, IL-4 and TNF-${\alpha}$ were significantly reduced by treated all concentrations of HHT. COX-2 on mRNA expression was reduced at treatment 2mg of HHT prior to stimulating by A23187. These results indicate that HHT has inhibition effects on allergy in this study.

  • Ponciri fructus, the unripe fruits of Poncirus trifoliata, are widely used in oriental traditional medicine as a remedy for inflammation, gastritis, emesis, digestive ulcers, allergy, and dysentery. To study the anti-wrinkle effects of Ponciri fructus extract (PFE) containing flavanone glycosides, PFE was fermented with Ganoderma lucidum mycelia and its biological activities were investigated. In Ponciri fructus extracts fermented with G. lucidum (G-PFE), polyphenol content was $1,021.00{\pm}0.50{\mu}g/mL$ and flavonoid content was $589.41{\pm}0.21{\mu}g/mL$. G-PFE was found to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and superoxide anion radical by a dose dependent manner, respectively. G-PFE showed higher antioxidant activity than that of PFE. In addition, the photoprotective properties of G-PFE was tested in human dermal fibroblasts (HDF) exposed to UVA radiation. G-PFE inhibited the activity of matrix metalloproteinase-1 (MMP-1) and showed a dose dependent decrease in the expression level of MMP-1. G-PFE also increased collagen biosynthesis in HDF. These results demonstrate that G-PFE could be useful as a potential cosmetic ingredient for anti-wrinkle.

  • Yijung-tang (YJT) is a traditional herbal formula comprising 4 medicinal herbs. In the present study, we performed the simultaneous analysis for three compounds of YJT and examined anti-allergic effects in vitro. The column for separation of three compounds was used Gemini C18 column and maintained at 40$^{\circ}C$. The mobile phase for gradient elution consisted of two solvent systems. To evaluate Th2 chemokines, YJT was treated into tumor necrosis factor (TNF)-${\alpha}$ and interferon (IFN)-${\gamma}$-stimulated HaCaT cells, and performed ELISA for thymus and activation regulated chemokine (TARC) and regulated on activation, normal T-cell expressed and secreted (RANTES). To measure Th2 cytokines, YJT was added into primary mouse splenocytes, and performed ELISA for interleukin (IL)-4, 5, 13. Calibration curves were acquired with r2 >0.9999. The contents of liquiritin, glycyrrhizin, and 6-gingerol in YJT were 4.50 mg/g, 11.10 mg/g, and 1.33 mg/g, respectively. YJT inhibited production of TARC and RANTES in TNF-${\alpha}$ and IFN-${\gamma}$-treated HaCaT cells. YJT also reduced production of IL-4, 5, and 13 in primary mouse splenocytes. In conclusion, our data will be a valuable information to improve quality control and anti-allergic effects of YJT.
