  • Objectives: We aimed to identify the dose-dependent inhibitory effects of Maekmundongcheongpye-eum and Liriopis Tuber on the mRNA expression of IL-6, IL-16, GM-CSF involved in the asthma model. Methods: In the study BEAS-2B cell lines, human epithelial cells were used. These cells were stimulated with tumor necrosis factor $(TNF)-{\alpha}$ for artificial inflammatory expression. ${\beta}-actin$ messenger RNA (mRNA) was used by internal standard. After 24 hours of Maekmundongcheongpye-eum, Liriopis Tuber-treatment, total cellular RNAs were collected, treating RNAzol directly on the alive cells. Then the transcriptional activities of IL-6, 16, GM-CSF were measured by RT-PCR with electrophoresis. Results: In the Maekmundongcheongpye-eum study, the mRNA expression of IL-6 showed 48% transcriptional inhibitory effect compared to the control group in the $100{\;}{\mu}l/ml$ category (P<0.001). In the IL-16, there was 53% and 57% transcriptional inhibitory effect compared to the control group in the $20{\;}{\mu}l/ml$ and $100{\;}{\mu}l/ml$ categories (P<0.001). In the GM-CSF, there was no inhibitory effect. In the Liriopis Tuber study, the mRNA expression of IL-6 showed 43% transcriptional inhibitory effect compared to the control group in the $100{\;}{\mu}l/ml$ category (p<0.005). In the IL-16, 34% and 26% of transcriptional inhibitory effect was shown compared to the control group in the $20{\;}{\mu}l/ml$ and $100{\;}{\mu}l/ml$ categories, respectively (P<0.05). In the GM-CSF, there was no inhibitory effect. Conclusions: This study shows that Maekmundongcheongpye-eum and Liriopis Tuber have dose-dependent inhibitory effects on the mRNA expression of IL-6 and IL-16 in BEAS-2B cell lines, human epithelial cells.

  • Objective : Allergic Inflammation is related with secretion of Cytokine. This study was performed to examine the effects of Woobangja on anti-allergic inflammation. Method : While macrophage 264.7cells was chosen as a normal group a control group was classified into three groups. One was stimulated with LPS. and another was pretreated with Woobangja for 1 hour. The third was pretreated with gydrocortisone for 1 hour. After the pretreatment, macrophage were incubated with lipopolysaccharide(LPS) 100 ng/ml for 12h and media collected and $TNF-{\alpha}$, IL-6, $IL-1{\beta}$, IL-10 concentration in supernatants were measured each by Enzyme linked immuno-sorbent assay. Woobangja were used $50\;{\mu}g/ml$, $100\;{\mu}g/ml$, $250\;{\mu}g/ml$, $500\;{\mu}g/ml$, 1 mg/ml. Hydrocortisones were used respectively $10^{-8}\;M$,$10^{-7}\;M$,$10^{-6}\;M$,$10^{-5}\;M$,$10^{-4}\;M$. Results : Woobangja showed inhibitory effect on $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. The inhibitory effect was most significant in 1mg/ml(p<0.01), and has increased according to the number of doses. Woobangja also showed inhibitory effect on IL-10 by LPS-stimulated macrophasg 264.7. The inhibitory effect was most significant in $100\;{\mu}g/ml$, and was not in a dose-dependent manner as Hydrocortisone group. Woobangja and Hydrocortison showed contrary effect on $IL-1{\beta}$ in al five concentration(p<0.01), and at the lowest concentration ($50\;{\mu}g/ml$) the level of $IL-1{\beta}$ was the lowest. On the other hand hydrocortison was observed to have inhibitory effect on $IL-1{\beta}$ in all five concentration(p<0.01). IL-6 was inhibited by hydrocortison in a roughly dose-dependent manner, but was not inhibited by Woobangja. On the contrary Woobangja obviously increased the expression of $IL-1{\beta}$ in all five concentration(p<0.01), but it was not related with concentrations. Conclusion : 1. Woobangja does significantly inhibit the expression of $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. 2. Woobangja does significantly increse the expression of IL-6 by LPS-stimulated macrophage 264.7. 3. Woobangja does significantly increse the expression of $IL-1{\beta}$ by LPS-stimulated macrophage 264.7. 4.

  • Objectives : To evaluate experimentally the clinical effect of Bojeongjeongcheon-tang, we observed the cytokines ($IL-1{\beta}$/TEX>, IL-4, IL-5, IL-6, IL-10, TNF-{\alpha},{\;}TGF-{\beta},{\;}IFN-{\gamma}$) and what effect they have on IgE in B cells of a rat. Methods : First of all, we extracted the spleens of healthy Balb/c mice and separated B cells from them. These B cells were cultured with anti-CD40 mAb (500 ng/ml), rmIL-4 (500 U/ml), Bojeongjeongcheon-tang (100 ug/ml, 10 ug/ml, 1 ug/ml). We used rmiL-10 (50 ng/ml) as a control group. Furthermore, we analyzed the expression of IgE, CD23, CD69 and the coherence of HRF in B cells using a flow cytometer. We also analyzed the cytokine gene expression in B cells by reverse transcriptase-PCR. We also measured B cells proliferation using the Liquid Scintillation Counter. Results : In this study, the Bojeongjeongcheon-tang treated group showed a tendency to decrease depending on the density compared with the control group in the expression of IgE+, CD23+, CD69, HRF. All of the Bojeongjeongcheon-tang treated group showed inhibitory effects with $IL-1{\beta}$, IL-4, IL-5 and proliferating effects with IL-6, IL-10, and $IFN-{\gamma}$ on cytokines transcript expression depending on the density. Meanwhile, $TNF-{\alpha}$ increased in all density. In IgE production, there was inhibitory effect on Bojeongjeongcheon-tang (both 100 ug/ml and 10 ug/ml) of significance (p < 0.01, p < 0.05). Also in B cell proliferation, the result revealed an inhibitory effect of Bojeongjeongcheon-tang (both 100 ug/ml and 10 ug/ml), of significance (p < 0.001, p < 0.01). Conclusions : This study shows that Bojeongjeongcheon-tang has an inhibitory effect on the production and activity of B cells. Also it inhibited CD23, IL-4 activity and IgE production and activation. It is obvious that Bojeongjeongcheon-tang treats asthma by inhibiting the production of histamine and HRF, IL-5 and proliferating IL-10. Also Bojeongjeongcheon-tang has some preventive effects on bronchial change by inhibiting $TGF-{\beta}$, which stimulates the bronchial transformation.

  • Morus alba L., known as white mulberry, is a medicinal plant belongs to family Moraceae. It has long been used commonly in Ayurvedic for the treatment of lung-heat, cough, asthma, hematemesis, dropsy and hypertension. In the present study, seven prenylated flavonoids, along with four benzofuran compounds were isolated by means of repeated column chromatography. The structures of the known compounds were identified as kuwanon G (1), kuwanon E (2), kuwanon T (3), morusin (4), sanggenon A (5), sanggenon M (6), sanggenol A (7), moracin R (8), mulberofuran G (9), mulberofuran A (10) and mulberofuran B (11), by comparing their spectroscopic data with those reported in the literature. For these isolates, containing trace compounds, the inhibitory activity against IL-6 production in $TNF-{\alpha}$ stimulated MG-63 cells was examined. All isolated compounds (1 - 11) showed excellent inhibitory activity against IL-6 production in $TNF-{\alpha}$ stimulated MG-63 cells. Especially this study is first time to report that sanggenon A (5), sanggenon M (6), sanggenol A (7), mulberofuran G (9), mulberofuran A (10) and mulberofuran B (11) showed the inhibitory activity of IL-6 production. Our study suggested the possibility of anti-inflammatory regulation by compounds (1 - 11) isolated from M. alba.

  • Allergic rhinitis is an inflammation of the nasal mucosa which is triggered by an allergic reaction. When exposed to certain allergens, the IgE covered mast cells degranulate releasing inflammatory mediators and cytokines which results 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 research effects of Sochungryong-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, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.005). 2. In IL-5 study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.05). 3. In JFN-${\gamma}$ study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.000001). 4. In Total IgE, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.000001). 5. In OVA-specific IgE, Sochungryong-tang treated group didn't showed significant inhibitory effect. Depending upon above results, it is considered that Sochungryong-tang has the inhibitory effect on the allergic rhinitis of mice and suggested that it could be used in relieving patients of the symptoms which are caused by allergic rhinitis.
