  • Background: BIOGF1K, a fraction of Panax ginseng, has desirable antimelanogenic, anti-inflammatory, and antiphotoaging properties that could be useful for treating skin conditions. Because its potential positive effects on allergic reactions in skin have not yet been described in detail, this study's main objective was to determine its efficacy in the treatment of atopic dermatitis (AD). Methods: High-performance liquid chromatography was used to verify the compounds in BIOGF1K, and we used the (3-4-5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide method to determine its cytotoxicity in RBL-2H3 and HMC-1 cell lines. RBL-2H3 cells were induced using both anti-DNP-IgE/DNP-BSA and calcium ionophore (A2187) treatments, whereas HMC-1 cells were induced using A2187 alone. To measure mast cell degranulation, we performed histamine (enzyme-linked immunosorbent assay) and β-hexosaminidase assays. To quantify interleukin (IL)-4, IL-5, and IL-13 levels in RBL-2H3 cells, we performed quantitative polymerase chain reaction (PCR); to quantify expression levels of IL-4 and IL-13 in HMC-1 cells, we used semiquantitative reverse transcription polymerase chain reaction (RT-PCR). Finally, we detected the total and phosphorylated forms of extracellular signal-regulated kinase, p-38, and c-Jun N-terminal kinase proteins by immunoblotting. Results: BIOGF1K decreased the AD response by reducing both histamine and β-hexosaminidase release as well as reducing the secretion levels of IL-4, IL-5, and IL-13 in RBL-2H3 cells and IL-4 and IL-13 in HMC-1 cells. In addition, BIOGF1K decreased MAPK pathway activation in RBL-2H3 and HMC-1 cells. Conclusions: BIOGF1K attenuated the AD response, hence supporting its use as a promising and natural approach for treating AD.

  • Objectives : Scutellaria barbata has been widely used in oriental medicine used for treatment of acute and chronic inflammatory diseases. In this study, to investigate the protective effect of Scutellaria barbata on type I allergic response, we determined whether Scutellaria barbata inhibits early or late allergic responses. Methods : To assess the effect of Scutellaria barbata Pharmacopuncture Extract(SB) in RBL-2H3 cells, we investigated the levels of the markers of degranulation such as ${\beta}$-hexosaminidase and histamine, inflammatory mediator such as IL-4, TNF-${\alpha}$, PGE2 and cysLT, and mRNA expression of cytokines and enzymes. In addition, we determined the levels of intracellular ROS by DCFH-DA assay and the free radical scavenging activity by DPPH method. Results : We found that SB suppressed the release of ${\beta}$-hexosaminidase and histamine and the production of IL-4, TNF-${\alpha}$, PGE2 and cysLT in RBL-2H3 by the antigen stimulation. SB also significantly inhibited the enzyme mRNA expressions, such as HDC2, COX-1, COX-2, 5-LOX and iNOS2, along with reduced cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ and GM-CSF in RBL-2H3. In addition, SB suppressed the levels of intracellular ROS. Conclusions : Our results indicate that SB protects against type I allergic response and exert an anti-inflammatory effect through the inhibition of degranulation, inflammatory mediator release and mRNA expression of cytokines and enzymes.

  • Objective : In the theory of Korean medicine, Scrophulariae Radix (SR) can clear away heat and cool the blood, nourish yin and promote the production of the body fluids, relieve toxin and benefit the throat. The present study was carried out to investigate effects of SR on allergic contact dermatitis (ACD) induced by 2,4-dinitrochlorobenzene (DNCB) in mice. Methods : In this experiment, effects of SR on clinical aspects on the skin, histopathological changes such as spongiosis, mast cell distribution, immune cell infiltration in tissue, spleen / body ratio and production levels of serum cytokines were investigated in vivo. In addition, effects on cell viability and release of b-hexosaminidase and histamine were also investigated in vitro. Results : SR treatment diminished erythema, desquamation and keratosis which were induced by repeated painting of DNCB. Spongiosis and edema were diminished by painting of SR in histopathological observation, infiltrations of mast cell and monocytes were also decreased in SR group. In addition, spleen / body ratio was lowered compared to ADC control group. Production level of IFN-${\gamma}$ in serum was decreased, but level of IL-4 did not affected by SR. Finally, more than 400 ${\mu}g/ml$ of SR treatment groups showed decreased cell viabilities in RBL-2H3 cells. Treatment with over 200 ${\mu}g/ml$ of SR decreased b-hexosaminidase release, and treatment with over 400 ${\mu}g/ml$ decreased histamine release in vitro. Conclusion : these data suggest that SR can decrease symptoms of ACD, then SR is useful to treat patient with ACD.

  • 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.

  • 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.

  • We examined the effects of essential oil from Thujopsis dolobrata Sieb. et Zucc. var. hondai Makino (EOTD) (Cupressaceae) on atopic dermatitis (AD)-like skin lesions in NC/Nga mice. Treatment with EOTD twice daily for two weeks ameliorate AD-like skin lesions induced by DNCB (2,4 dinitrochlorobenzene), and clinical scores were reduced to 7.29, 7.07, and 4.5 points in the groups treated with 1.5%, 3.0%, and 6.0% extract (p<0.01) respectively, from the 15.0 score obtained using vehicle. EOTD inhibited the infiltration of mast cells into the AD-like skin lesion in NC/Nga mice (p<0.01) and also reduced serum histamine and IgE levels (p<0.05). Furthermore, it dose-dependently inhibited the release of beta-hexosaminidase from rat basophilic leukemia RBL 2H3 cells. These results indicate that EOTD reduces AD-like skin lesions by inhibiting the production of IgE and histamine, and, thus, IgE-mediated degranulation.

  • Gamipaidok-san(GPDS) is the Hyungbangpaidok-san prescription fortified with the additional ingredients known to be effective for dermatitis. So it has been used for atopic dermatitis in the clinic work actually. In this study, we investigated the effects of GPDS on in vitro and in vivo anti-allergic effect on RBL-2H3 rat basophilic leukemia Cells and on IgE-induced passive cutaneous anaphylaxis (PCA) in mice. The in vitro anti-inflammatory activity of GPDS in RAW 264.7 cells was investigated. GPDS potently inhibited $\beta$-hexosaminidase release from RBL-2H3 and the IgE-mediated PCA reaction in mice. GPDS inhibited LPS-induced NO and PGE2 production in a dose-dependent manner Furthermore, It also inhibited inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein expression in RAW 264.7 cells, and the activation of the transcription factor, NF-kB, in nuclear fraction. The antiallergic action of GPDS may originate from anti-inflammatory activities, and can improve the inflammation caused by allergies.

  • The fruits of Foeniculum vulgare (Foeniculi Fructus) have been widely used in Chinese medicine as an antiemetic, ameliorating stomach ailments and as an analgesic. In order to establish its potential for antiallergic use, inhibitory actions of the fruit on 5-lipoxgenase (5-LOX) and ${\beta}$-hexosaminidase release were evaluated. The 70% ethanol extract of this plant material (FR) considerably inhibited 5-LOX-catalyzed leukotriene production from A23187-induced rat basophilic leukemia (RBL)-1 cells. The $IC_{50}$ was $3.2{\mu}g/ml$. From this extract, 12 major compounds including sabinene, fenchone, ${\gamma}$-terpinene, ${\alpha}$-pinene, limonene, p-anisylacetone, panisylaldehyde, estragole (4-allylanisole), trans-anethole, scopoletin, bergapten and umbelliferone were isolated. And it was found that several terpene derivatives including ${\gamma}$-terpinene and fenchone as well as phenylpropanoid, trans-anethole, showed considerable inhibitory action of 5-LOX. In particular, the $IC_{50}$ of trans-anethole was $51.6{\mu}M$. In contrast, FR and the isolated compounds did not show considerable inhibitory activity on the degranulation reaction of ${\beta}$-hexosaminidase release from antigen-treated RBL-2H3 cells. Against arachidonic acid-induced ear edema in mice, FR and trans-anethole showed significant inhibition by oral administration at doses of 100-400 mg/kg. In conclusion, FR and several major constituents are 5-LOX inhibitors and they may have potential for treating 5-LOX-related disorders.

  • This study aimed to investigate the effects of Sesami Semen on the itching and anti-allergic inflammation mechanism related with cytokine, chemokine, histamine, $\beta$-hexosaminidase, NF-$\kappa$B, and free radical, and it was concluded as follows : 1. Sesami Semen did not show any cytotoxicity at the range of con-centration (1-250 ${\mu}g/m\ell$) on the human fibroblast cell (hFCs). 2. Sesami Semen reduced the gene expressions of IL-8, TNF-$\alpha$, IL-6 mRNA comparing with control. 3. Sesami Semen reduced the levels of IL-6, IL-8, MCP-1 within THP-1 cell depending on the concentration, and especially significantly reduced the the levels of IL-6, MCP-1 at all the concentration. 4. Sesami Semen significantly decreased the histamine secretion on HMC-1 at all the concentration. 5. Sesami Semen decreased the $\beta$-Hexosaminidase secretion 6.2% at 10 ${\mu}g$/ml conc., 58.3% at 100 ${\mu}g$/ml conc. and 63.2% at 200 ${\mu}g$/ml conc., respectively. And IC50 (${\mu}g$/ml) was 158.25 ${\mu}g$/ml. 6. Sesami Semen significantly suppressed the activity of NF-$\kappa$B promoter depending on the concentration. 7. Sesami Semen decreased the production of reactive oxygen species (ROS) and DPPH generation depending on the concentration. As judged with above results, the effects of Sesami Semen on the anti-allergic inflamation would be recognized, and it could be applied on the medicinal sources for prevention or treatment of several allergy disease. And more studies are needed furthermore with the seperation of effective materials.
