The purpose of this research was to investigate the effects of Bopaewon-tang (BT) on allergic reaction. In the present study, we examined the effect of BT on type 1 and type tV allergic reaction. BT (500 mg/kg) did not affect the systemic anaphylaxis induced by compound 48180 and the passive cutaneous anaphylaxis induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin in vivo. Also, BT did not affect the release of histamine from peritoneal mast cells in rats. In addition, BT did not affect the permeability of evans blue into peritoneal cavity, but inhibited the writhing syndrome induced by acetic acid. BT inhibited the delayed type hypersensitivity induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene. These results indicate that BT may be useful for the prevention and treatment of type IV allergy related disease.

The anti-allergic effect of the methanol extract of Zizania latifolia Turcz was investigated. Methanol extract of Z. latifolia Trucz did not display any cytotoxicity activities in the IgE-sensitized RBL-2H3 cells. The extract was found to inhibit compound 48/80-induced degranulation and antigen-induced $\beta$-hexosaminidase release as well as PMA plus A23187-induced TNF-$\alpha$ production in RBL-2H3 mast cells in a dose-dependent manner. Release of $\beta$-hexosaminidase, a marker for the release of histamine in mast cells, was inhibited with an $IC_{50}$ value of $73.8\;{\mu}g/mL$. These results suggest that Z. latifolia extracts may be useful for the prevention of type I allergic reaction.

To understand the anti-allergic mechanism of compound K, which is a metabolite of ginsenoside Rb1, a main constituent of the root of Panax ginseng C.A. Meyer (family Araliaceae), its inhibitory effect against IgE-antigen complex IAC)-induced passive cutaneous anaphylaxis (PCA) reaction in mice and mRNA and protein expressions of allergic cytokines in lAC-stimulated RBL-2H3 cells were investigated. Orally administered ginsenoside Rb1 more potently inhibited PCA reaction when administered at 5 h prior to the lAC treatment than when administered at I h before. However, compound K orally administered 1 h before lAC treatment showed a more potent anti-PCA reaction effect than when treated at 5 h before. Orally administered ginsenoside Rb1 more potently inhibited PCA reaction induced by lAC in mice than intraperitoneally treated one, apart from orally administered its metabolite, compound K, which was more potent than the orally administered one. The compound K, a metabolite of ginsenoside Rb1, inhibited mRNA and protein expressions of IL-4 and TNF-${\alpha}$ and the activation of their transcription factor NF-$\kappa$B and MAPK in lAC-stimulated RBL-2H3 cells. These findings suggest that orally administered ginsenoside Rb1 may be dependent on its metabolism by intestinal microflora in the intestine and the compound K may improve allergic diseases by the inhibition of IL-4 and TNF-${\alpha}$ expresseion.

Objectives: Maier symptoms of allergic rhinitis are nasal obstructions, sneezing and watery rhinorrhea. When exposed to certain allergens, the IgE covered mast cells degranulate and release inflammatory mediators and cytokines which result in a local inflammatory reaction. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of allergic rhinitis. This experimental study was done to reveal the effects of the Bojungikgi-tang on the allergic rhinitis. We have studied effect of mice on OVA-induced production of IL-4, IL-5, $INF-{\gamma}$ by murine splenocytes and effect of OVA-induced Total IgE and OVA-specific IgE Meterial and Metheds: 21 BALB/c rats were divided into three groups: normal group, control group, experimental group. To induce the allergic rhinitis in control group and experimental group, rats were sentitized intraperitioneally with 0.1% ovalbumin solution 3 times at intervals of 2 weeks. Then intranasal sensitization was performed by diffusing 0.1% ovalbumin solution 3 times at intervals of 2 days for a week. After that time, rats in experimental group were oral administration treated by the Bojuogikgi-tang fer 28 days. We observed changes of IL-4, IL-5, $INF-{\gamma}$, Total IgE and OVA-specific IgE. We used independent-test statistically. Results: 1. In IL-4 study, Bojungikgi-tang treated group didn't show significant differences. 2. In IL-5 study, Bojungikgi-tang treated group shows significant differences. 3. In $INF-{\gamma}$ study, Bojungikgi-tang treated group shows significant differences. 4. In Total IgE, Bojungikgi-tang treated group shows significant differences. 5. In OVA-specific IgE, Bojungikgi-tang treated group didn't show significant differences. According to this result, Bojungikgi-tang was concluded to be effective on lowering the total IgE. Through this. Bojungikgi tang seems to reduce the symptoms of allergic rhinitis. More studies are required to know exact mechanism of Bojungikgi tang to show the anti allergenic effect.

Portulaca oleracea L. is known to have many biological benefits such as anti-oxidant, anti-inflammatory, anti-allergic and anti-tumor. The objective of this study is to explore the neuroprotective effect of P. oleracea L. against glutamate-induced oxidative stress in mouse hippocampal HT22 cells. P. oleracea L. 70% ethanol extract and solvent fractions have the potent neroprotective effects on glutamate-induced nerotoxicity by induced the expression of heme oxygenase (HO)-1 in HT22 cells. Especially, ethyl acetate fraction showed higher protective effect. In HT22 cell, P. oleracea L. treatment with ERK inhibitor (PD98059) and c-JUN N-terminal kinase (JNK) inhibitor (SP600125) reduced P. oleracea L. ethyl acetate fraction induced HO-1 expression and P. oleracea L. ethyl acetate fraction also increased ERK and JNK phosphorylation. Furthermore, we found that treatment of P. oleracea L. caused the nuclear accumulation of Nrf2. In conclusion, the ethyl acetate fraction of 70% ethanol extract of P. oleracea L. significantly protect glutamate-induced oxidative damage by induction of HO-1 via Nrf2, ERK and JNK pathway in mouse hippocampal HT22. Taken together these finding suggest that P. oleracea L. ethyl acetate fraction is good source for taking active compounds and may be a potential therapeutic agent for brain disorder that induced by oxidative stress and neuronal damage.

Purpose : The objective of present study is to detect the effect of Sopungsan aqueous extracts (SPS) on the passive cutaneous anaphylaxis (PCA; type I allergic dermatitis) Method : 500, 250 and 125mg/kg of SPS were orally administered 12 hr-interval before antigen challenge (total 4 times administered). PCA reactions were induced using rat anti-ovalbumin (OVA) serum contain IgE (titer 1:32) as sensitization and OVA as antigen challenge. 30 min after antigen challenge, the diameter of blue-dye spots (evans blue) and leaked amount of dye were observed with histology and histomorphometry at the PCA induced sites. In addition, serum total IgE and histamine levels were also observed by ELISA, respectively. The effects of SPS were compared with dexamethasone 1mg/kg treated rats in the present study. Results : As results of PCA reaction, vasodilation related increase of diameter of blue-dye spot and amount of leaked dye were observed with swelling and edematous changes in the dermis of PCA induced sites. However, these changes on PCA reactions were dramatically and dose-dependently decreased by treatment of SPS as compared with vehicle control. In addition, serum elevations of IgE and histamine were also dose-dependently inhibited by treatment of SPS as compared with vehicle control respectively. The effects of SPS 500mg/kg were similar to that of dexamethasone 1mg/kg in the present study. Conclusion : Base on the results of the present study, it is concluded that SPS has favorable effect on the PCA-induced allergic dermatitis, and SPS 500mg/kg showed similar favorable effects as compared with dexamethasone 1mg/kg. The present findings demonstrate that SPS can be effective for the prevention and treatment of allergic dermatitis.

Objectives: Gagamyanggyeoksan (G-YGS) has been used to suppress allergic reaction, however, the cellular target of G-YGS and its mode of action remain unclear. The present study was designed to investigate the effect of extracted G-YGS on the PMA and lonomycin (PI)-induced activation of RBL-2H3. Methods: For this investigation, We examined IL-4, IL-13 mRNA expression by Real-Time PCR, IL-4, IL-13 production by ELISA analysis and manifestations of GATA-1, GATA-2, NF-AT1, NF-AT2, AP-1 and NF-${\kappa}B$ p65 transcription factors by western blotting, OVA-specific IgE, IL-4, IL-13 by mouse be sensitive to OVA. Results: Here we showed that treatment of RBL-2H3 mast cells with G-YGS, suppressed PI-induced production of Th2 cytokines including IL-4 and IL-13 in a dose dependent manner. The mRNA expression of IL-4 were completely abolished by G-YGS at the concentration of $100{\mu}g/ml$. Data from a stable cell lines consistently expressing IL-4. And the mRNA expression of IL-13 were abolished by G-YGS at the $200{\mu}g/ml$. But there is no difference between the $50{\mu}g/ml$, the $100{\mu}g/ml$ and the comparison. Results from the western blot analysis of transcription factors involving IL-4 and IL-13 expression indicated that it prominently decreased the expression of mast cell specific transcricption factors including GATA-1, GATA-2, NF-AT2, c-Jun, NF-${\kappa}B$ p65 but not c-Fos. And G-YGS suppressed IgE, IL-4, IL-13 in mouse be sensitive to OVA. Conclusions We suggested the anti-allergic activities of G-YGS might be mediated by down-regulation of Th2 cytokines such as IL-4 and IL-13 through the regulation of transcription factors as GATA-1, GATA-2, NF-AT2, c-Jun, NF-${\kappa}B$ p65.

Gnaphalium affine D. DON (GA) has been used as a vegetable as well as a folk medicine in East Asia. The antioxidant and anti-complementary activity of GA extract (GAE) has also been reported. However, little is known about its anti-inflammatory and anti-allergic effect and mechanism of action. In this study, we evaluated the inhibitory effects of GAE on the production of inflammatory mediators such as NO, $PGE_2$, TLR4, eotaxin-1 and histamine. Our results suggest that GAE inhibits the production of NO and $PGE_2$ by inhibiting transcriptional activation via the involvement of iNOS and COX-2. The LPS-induced expression of Toll-like receptor 4 (TLR4) was also attenuated. In addition, GAE inhibited A23187-induced histamine release from MC/9 mast cells. It also inhibited the production of eotaxin-1 induced by IL-4. Collectively, these results suggest that GAE may have considerable potential as a cosmetic ingredient with anti-inflammatory and anti-allergic properties.
