  • In previous report, Seungmagalgeun-tang (SGT) could exert its anti-inflammatory actions in the BV-2 microglial cells. However, study on the anti-inflammatory effect of SGT in mast cells has not been identified. Therefore, we examined on the anti-inflammatory effect of SGT on the phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187-induced rat basophilic leukemia (RBL-2H3) cells. SGT inhibited the release of ${\beta}$-hexosaminidase and secretion and expression of pro-inflammatory cytokines such as tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-4 on RBL-2H3 cells, without affecting cell viability. The protein expression level of nuclear factor (NF)-${\kappa}B$ (p65) was decreased in the nucleus by SGT. In addition, SGT suppressed the degradation of inhibitory protein $I{\kappa}B-{\alpha}$ protein, the activation of p38 mitogen-activated protein kinase (MAPK), and the expressions of cyclooxygenase (COX)-2 mRNA and protein level in RBL-2H3 cells. These results suggest that SGT could be involved anti-allergic effect by control of NF-${\kappa}B$ (p65) translocation into the nucleus through inhibition of $I{\kappa}B-{\alpha}$ degradation and suppression of COX-2 expression.

  • We investigate the effect of endoplasmic reticulum (ER) stress inhibitor treatment during parthenogenetic activation of oocytes on the ER stress generation, apoptosis, and in vitro development of parthenogenetic porcine embryos. Porcine in vitro matured oocytes were activated by 1) electric stimulus (E) or 2) $E+10{\mu}M$ Ca-ionophore (A23187) treatment (EC). Oocytes were then treated by ER stress inhibitors such as salubrinal (200 nM) and tauroursodeoxychloic acid (TUDCA, $100{\mu}M$) for 3 h prior to in vitro culture. Parthenogenetic embryos were sampled to analyze ER stress and apoptosis at the 1-cell and blastocyst stages. The x-box binding protein 1 (Xbp1) mRNA and ER stress-associated genes were analyzed by RT-PCR or RT-qPCR. Apoptotic gene expression was analyzed by RT-PCR. At the 1-cell stage, although no difference was observed in Xbp1 splicing among treatments, BiP transcription level in the E group was significantly reduced by salubrinal treatment, and GRP94 and ATF4 transcription levels in EC group were significantly reduced by all treatments (p<0.05) compared to control. In the EC group, both apoptotic genes were reduced by ER stress inhibitor treatments compared to control (p<0.05) except Caspase-3 gene by TUDCA treatment. These results suggest that the treatment of ER stress inhibitor during parthenogenetic activation can reduce ER stress, and thereby reduce apoptosis and promote in vitro development of porcine parthenogenetic embryos.

  • This study was designed to investigate effects of calcium antagonists on endothelial and neuronal dysfunction of right coronary artery (RCA) induced by ischemia- reperfusion in anesthetized, open-chest pigs. After reperfusion, pigs were sacrificed and the RCA was rapidly dissected for in vitro experiments. Experimental groups were divided into 4 groups: control (C-RCA), ischemia-reperfusion only (I-RCA), verapamil infusion (VI-RCA) and nifedipine infusion (NI-RCA) group, respectively. The ischemia did not affect hemodynamics, mean arterial pressure, heart rate, LVdP/dtmax, and decreased RCA flow. Arterial pressure and heart rate during ischemia-reperfusion were decreased in VI-RCA and NI-RCA, and RCA flow during reperfusion was increased in NI-RCA. 5-Hydroxytryptamine (5-HT) produced concentration-dependent contractions in C-RCA. The 5-HT-induced contractions were potentiated in I-RCA and VI-RCA, but not in NI-RCA. Endothelium-dependent relaxation by calcium ionophore A23187 was inhibited in I-RCA and VI-RCA, and recovered in NI-RCA. Cyclic GMP contents were decreased in I-RCA group alone. Electrical field stimulation in C-RCA produced transient and frequency-dependent contractions and at 50 Hz caused biphasic contractions. The transient contractions were not affected by pretreatment with phentolamine and atropine, but the biphasic contraction was altered by the pretreatment. Both contractions were inhibited in I-RCA, and were partially recovered in VI-RCA and NI-RCA. Ischemia-reperfusion of RCA in pigs causes endothelial and neuronal dysfunctions, and calcium antagonists partially prevent both.

  • Objectives : Ulmus davidiana (UD) has been widely used in Korean herbal medicines used for treatment of acute and chronic inflammatory diseases, such as rhinitis, asthma, and abscess. In this study, To investigated the protective effect of UD on type 1 allergic response, we determined whether UD inhibits early and late allergic response. Methods : The effect of UD was analyzed by ELISA and RT-PCR in RBL-2H3 cells. Levels of ${\beta}$ -hexosaminidase, interleukin (IL)-4 and TNF-${\alpha}$ were measured using enzyme-linked immunosorbent assays (ELISAs). mRNA levels of COX-2 and T-helper type 2(Th2) cytokines were analyzed with RT-PCR. Results : We found that UD suppressed ${\beta}$-hexosaminidase release in RBL-2H3 not only by the PMA plus A23187 stimulation, but also by the IgE-DNP-HSA stimulation at the antigen-antibody binding stage and antibody-receptor binding stage. UD also significantly inhibited COX2 level, along with reduced Th2 cytokine levels, such as IL-3, IL-4, IL-5, IL-13, GM-CSF, and TNF-${\alpha}$ in RBL-2H3. Conclusions : Our results indicate that UD protects against type 1 allergic response and exerts an anti-inflammatory effect through the inhibition of degranulation and expression of COX2 and Th2 cytokines.

  • Soyangin-Hyeongbangpaedok-san(SHBPDS) is used for treating upper respiratory infections, In an effort to investigate the anti-inflammatory effects of SHBPDS, we measured production of several cytokines and immunoglobulin in various immune cells. SHBPDS decreased the secretion of TNF-${\alpha}$, but not that of IL-6 in PMA/A23187 stimulated HMC-1 cells. As for mouse B cells, it induced proliferation and caused differential effects in expressions of surface IgE as determined by flow cytometry and secretions of IgE, IgG1, ILA and INF-${\gamma}$as measured by ELISA but showed little change in CD23 or CD69 expression. SHBPDS increased proliferation in anti-CD3/anti-CD28 stimulated CD4 Th cells. Under the Th1/Th2 polarization conditions, SHBPDS at 200 ${\mu}g/m{\ell}$ suppressed the secretion of INF-${\gamma}$ and IL-4. Based on the above results, we conclude that SHBPDS has antiinflammatory activities in mast cells and different immunomodulatroy effects in B cells and Th cells.

  • In the present study, we investigated the anti-allergic effect of the water extract of Bopyeoyangyeong-jun(BYJ). To investigate the biological effect of BYJ, We examined cytotoxicity and inflammatory cytokine secretion with RBL-2H3. We examined Cell Viability, ${\beta}$-hexosaminidase, tumor necrosis factor-alpha(TNF-${\alpha}$), interleukin(IL)-4 secretion from RBL-2H3 cell after pre- treatment with Bopyeoyangyeong-jun of 1 mg/ml, 2 mg/ml. RBL-2H3 cell was stimulated with phorbol 12-myristate 13-acetate(PMA) and calcium ionophore A23187. BYJ by itself had no effect on viability of RBL-2H3 cell. We observed that Bopyeoyangyeong-jun reduced ${\beta}$-hexosaminidase, TNF-${\alpha}$, IL-4 secretion in RBL-2H3 cell. Taken together, these results indicate that Bopyeoyangyeong-jun has anti-histamic effect and controls TNF-${\alpha}$, IL-4 secretion on allergic reaction.

  • 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.

  • In order to demonstrate whether ovoperoxidase hardens the zona of oocytes activated by incubating in M-S buffer supplemented with 20$\mu$M of Ca-ionophore A 23187, the effect of peroxidase inhibitors(250mM pheylhydrazine, 28mM sodilum sulfite, 350mM glycine ethyl ester and 50mM sodium azide), tyrosine analogue(12.5mM tyramine) and exogeneous peroxidase(50$\mu\textrm{g}$/ml horseradishperoxidase ; HRP) on zona hardening in ionorphore-treated oocytes were investigated. The results obtained from thses experiments were summarized as follows : 1. The zona solubility (t50) of ionophore-activated and DMSO-treated oocytes at 1, 2 and 3 hr of culture were 25.0, 31.6 and 40.6min., and 9.7, 10.8 and 15.5 min., respectively. The longest time required for zona lysis of ionophore activated oocytes at 1 hr after onset of ionophore treatment. The diferences int50 for zona was significantly greater as compared to DMSO-treated controls(P<0.01). 2. The inhibition rates of hardening in the oocytes treated with the phenylhydrazine, sodium sulfite, glycine ethyl ester and sodium azide, were 23.8, 61.9, 95.2 and 23.8%l, respectively, and the tyramine, was 14.3%. Several known peroxidase inhibitors and tyrosine analogue were blocked zona hardening in ionophore activated oocytes. 3. The treatment of exogeneous peroxidase promoted the zona hardening of activated oocytes but not unactivated oocytes. These resuls indicate that the ovoperoxidase apparently catalyzes the hardening of the zona following ionophore activation of mouse oocytes.

  • Objective : The genus Glycyrrhiza has been used in food and traditional herbal medicine. Many experimental studies reported that Glycyrrhiza species possess several pharmacological properties. Glycyrrhiza new varieties WONGAM and SINWONGAM have been developed by Korea Rural Development Administration doing research for registration on Ministry of Food and Drug Safety. During the evaluations about pharmacological effect of Glycyrrhiza new varieties WONGAM and SINWONGAM, we focused the anti-allergic effect in this study. Methods : We investigated the anti-allergic effect of WONGAM and SINWONGAM compared with Glycyrrhiza uralensis Fischer and G. glabra L. using anti-dinitrophenyl-immunoglobulin E (IgE)/human serum albumin-stimulated RBL-2H3 cells, phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated HMC-1 cells and compound 48/80-induced anaphylaxis mice model. We analyzed the effect on the expression of various cytokines, and IgE from mast cells and the underlying molecular mechanisms of WONGAM and SINWONGAM in presented models. Results : WONGAM and SINWONGAM showed the inhibitory effect on the histamine release from rat peritoneal mast cells or human mast cells without cytotoxicity. WONGAM and SINWONGAM blocked anaphylactic shock and decreased the IgE production. Furthermore, WONGAM and SINWONGAM inhibited the productions of TNF-α and IL-6 in compound 48/80-induced anaphylaxis mice model. Conclusion : These results indicated that WONGAM and SINWONGAM would have protect effect on allergic responses through the inhibition of allergic mediators and pro-inflammatory cytokines. This study may facilitate the development on Glycyrrhiza new varieties for allergy.
