The effects of extracts from various Oriental medicinal herbs on mast-cell-mediated allergic reactions were investigated in this study. Out of these extracts, the medicinal herb Atractylodis rhizoma alba exhibited the most potent activity in the cells, with $IC_50$ values of $20.5\;{\mu}g/ml$, by DNP-BSA and $33.04\;{\mu}g/ml$, by compound 48/80. Similar to the in vitro activity, Atractylodis rhizoma alba inhibited compound-48/80-induced systemic anaphylaxis by 31.3% at 300 mg/kg in mice. It also suppressed the secretion of $TNF-{\alpha}$, a major pro-inflammatory cytokine in the cells. These results may suggest that Atractylodis rhizoma alba shows anti-allergic activity in compound 48/80-induced anaphylactic mice through the inhibition of mast cells.

The present study was conducted to investigate the anti-allergic activity of Saingheylyunbooem(SHU)). We investigated the anti-allergic effects of SHU in RBL-2H3 basophilic leukemia cells by compound 48/80, a mast cell degranulator in mice. SHU inhibited ${\beta}$-hexosaminidase and histamine release from compound 48/80 stimulated RBL-2H3 cells. The in vitro anti-inflammatory activities of SHU in LPS-stimulated RAW 264.7 cells were investigated. SHU inhibited NO production effectively dowregulated the expression of iNOS mRNA and iNOS protein expression in LPS-stimulated RAW 264.7 cells. These result provide evidences that SHU may be beneficial in the treatment of allergic inflammtory disease.

We investigated the effects of butanol fraction of Asterias amurensis (BFA) on the anti-allergic activity. BFA inhibited both cyclooxygenase-2 dependent prostaglandin $D_2$ and 5-lipoxygenase dependent leukotriene $C_4$ generation in a concentration-dependent manner with $IC_{50}$ values of 174.6 and 22.2 ${\mu}g$/ml, respectively. In addition, BFA also inhibited the degranulation in a dose dependent manner. Furthermore, oral administration of BFA inhibited IgE-mediated passive cutaneous anaphylaxis in mice. These results suggested that BFA may be useful in regulating mast cell-mediated allergic diseases.

Asthma is a chronic obstructive lung disease characterized by recurrent episodes of bronchoconstriction and wheezing. Conventional asthma treatment involves the suppression of airway inflammation or improving airway flow. Rosmarinus officialis, also known as rosemary, is a Mediterranean plant that is used for the treatment of inflammatory diseases. Carnosol, a diterpenoid found in rosemary extracts, has been known to exhibit anti-inflammatory, anti-tumor, and anti-oxidant effects. The effect of carnosol on allergic responses has not been tested yet. The effect of carnosol on a murine allergic asthma model were investigated. Carnosol inhibited the degranulation of RBL-2H3 mast cells. Carnosol treatment inhibited the increase in the number of eosinophils in the bronchoalveolar lavage fluids (BALF) of mice treated with ovalbumin. Carnosol treatment also inhibited inflammatory responses and mucin production in histologic studies. Carnosol treatment inhibited the increases of IL-4 and IL-13 cytokines expression in both BALF and the lungs. These results suggest that carnosol may have a potential for allergic asthma therapy.

Major symptoms of allergic rhinitis are nasal obstructions, sneezing and watery rhinorrhea. Gamigyeji-tang has been used to treat for watery rhinorrhea, which is one of the symptoms of allergic rhinitis. This experimental study was done to rescarch effects of Gamigyeji-tang. We have studied effect of mice on OVA-induced Production of IL-4, IL-5, IFN-${\gamma}$ by Murine Splenocytes, and effect of OVA-induced total IgE and OVA-Specific IgE. The results were as follows ; 1. In IL-4 study, Gamigyeji-tang treated group was proved significant inhibitory effect(p〈0.005) 2. In IL-5 study, Gamigyeji-tang treated group was proved significant inhibitory effect.(p〈0.05) 3. In IFN-${\gamma}$ study, Gamigyeji-tang treated group was proved significant inhibitory effect(p〈0.000001) 4. In Total IgE, Gamigyeji-tang treated group didn't showed significant inhibitory effect. 5. In OVA-specific IgE, Gamigyeji-tang treated group didn't showed significant inhibitory effect. According to this result, Gamigyejj-tang was concluded to be effective on anti-allergic action. More studies are required to investigate the mechanism of inhibition by herbal medicine in allergic rhinitis model.

Since the main symptoms of COVID-19 involve the respiratory system, the infection rate of this disease is predicted to be higher in patients with other respiratory conditions such as allergic rhinitis. In such a situation, it will be meaningful to conduct research on an allergy treatment that has fewer side effects and can effectively reduce allergy symptoms. Here, we prepared experimental samples under various fermentation conditions with mixed extracts of six medicinal plants. To examine the anti-allergic efficacy of these samples, an egg albumin-induced allergic rhinitis animal model experiment, a serum histamine and IgE experiment, and a COX and LO inhibitory activity experiment were conducted. As a result of animal experiments, OVA+SP-4 showed superior efficacy compared to OVA+SP-1 in nasal rubbing and sneezing experiments and had anti-allergic efficacy similar to that of OVA-cetirizine. The serum histamine concentration of OVA+SP-4 was also 1.3 times higher than that of the OVA+cetirizine group, showing a high histamine reduction ability, and IgE showed the same trend. An analysis of COX inhibitory efficacy also confirmed that COX-1 and COX-2 inhibitory efficacy is high, and the longer the fermentation time, the higher the antiallergic efficacy. The composition proposed by this study is expected to have a significant effect on sustainable allergy prevention and treatment in the future by applying it to human patients.

Effects of Panax ginseng on allergic reactions were studied uslng various in vivo and in vitro experimental models such as 48-hr passive cutaneous anaphylaxis, mediators-induced skin reactions, histamine release from rat peritoneal mast cells, hexosaminidase release from RBL-2H3 cells, and lipoxygenase assay . In all of anti-allergic experiments we conducted, ginseng components (50% ethanol extract or ginseng total saponin or ginsenosides) extracted from Korean red ginseng, did not show significant anti-allergic actions. In 48-hr passive cutaneous anaphylaxis and mediators-induced skin reactions, 50% ethanol extract did not suppress hypersensitivity reactions. Total saponin, 50% ethanol extract, and 8 major ginsenosides did not show inhibitory effects on lipoxygeanse activity. Ginseng total saponin did not inhibit histamine release from rat peritoneal mast cells. All of the ginseng components mentioned above were also tested on RBL-2H3 cells, but none of them inhibited hexosaminidase release from this cell line. These results suggest that Panax ginseng does not have effects on allergic reactions at the level of 50% ethanol extract or total saponin used. All of 8 major saponin components tested ($Rb_1$, $Rb_2$, Rc, Rd, Re, Rf, $Rg_1$, $Rg_2$), did not inhibit lipoxygenase activity and degranulation events.

Objectives : This study was carried out to investigate the anti inflammatory and anti allergy effects of Vitex rotundifolia Linne fil. extract(VRE). Results : 1. In vitro test, VRE was used to determine the modulation of cytokine secretion, the activation of inflammatory and allergic factor and the inhibition of gene expression. The cell survival rate of Raw 264.7 and Jurkat T cells didn't decrease and accordingly cytotoxicity wasn't observed. In anti-allergic assay, the secretion of IL-2, TNF-${\alpha}$, IL-4, IL-5 and IFN-${\gamma}$ were suppressed on Jurkat T cells induced by dust mites. And the gene expression of COX-2 was suppressed in HMC-1 stimulated by calcium ionophore A23187. In anti-inflammatory assay, the gene expression of TNF-${\alpha}$, COX-2 were suppressed on LPS-activated Raw 264.7 cells. And the secretion of IL-6 and IL-8 were suppressed on EoL-1 cells induced by dust mites. P38 and ERK activation of MAPK decreased generally. VRE showed potent inhibitory activity of NO production. 2. In vivo test, we used NC/Nga mouse induced by atopic dermatitis to observe the effects of VRE on the weight, water and feed, blood test, weight of organs, total IgE and histological change of main organs. Quantity of water and feed were not changed, therefore it didn't affect the weight directly, and no change was observed in related main organs, thus maybe there is no organ toxicity by test substances. And the symptoms were decreased significantly, and the thickness of epithelial cell layer and the number of mast cells were inhibited significantly by the difference of dosage. The number of total complete blood cells and IgE in serum were not changed significantly. Conclusion : These results suggest that VRE has anti-inflammatory and anti-allergic effects. Therefore VRE could be used effectively on improvement or treatment of atopic dermatitis. However, further study is needed to prove which component of VRE indicates effective pharmacological action.
