        길경탕(桔梗湯)이 인체(人體) 폐세포(肺細胞)에 미치는 영향(影響)에 관(關)한 분자생물학적(分子生物學的) 연구(硏究)

        이형구,Rhee, Hyung-Koo 대한한의학회 1999 대한한의학회지 Vol.20 No.2

        To characterize the effects of Gilgyung-Tang(GGT) on cellular proliferation and viability of normal lung fibroblast cells, we examined the cell cycle progression and cell cycle-related gene expression in T3891 using a flow cytometry and a quantitative RT-PCR analysis. 1. The significant surpression effect of cellular proliferations of GGT was observed in proportion to a certain concentration and time. 2. GGT was identified to induce apoptotic death of damaged cells by treatment with a DNA-damage agent and etoposide, while it stimulated the recovery of cellular viability of normal cells. 3 The significant reductions of mRNA expression of PCAN, c-Fos treated by GGT were observed. 4. The significant inductions of mRNA expression of p53, CDKN1. Gadd45 treated by GGT were observed. 5. The apoptosis caused by the reduction of Bcl-2 genes was significant and the Bax genes were increased. but the amount of Fas genes were not changed. These results strongly suggest that GGT triggers arrest of the cell cycle at G1 phase, and thus causes an inhibition of cellular proliferation of human normal lung cells through the transcriptional up-regulation of cell cycle inhibitory genes and down-regulation of induction of cell cycle stimulating genes respectably.

        Background & Objective : Idiopathic Lung Fibrosis(IPF) is chronic fibrotic interstitial pneumonia. The pathogenesis is unclear. Fritillariae Rhizoma is the most commonly used antitussive and expectorant Oriental medicinal herb. The effects of Fritillariae Rhizoma on bleomycin-induced lung fibrosis is here evaluated. Material and Methods : Fritillariae Rhizoma extract was daily given to the normal rats, control(bleomycin) rats and treated(bleomycin and Fritillariae Rhizoma) rats at 9.0 mg per body weight 10g for 14 days. 14 days later, the change in Leukocyte count and percentages were observed, as well as IFN-gamma and 1L-4 in BALF, and the change in Semiqualitative histological index(SHI). Results : Compared to control rats, Fritillariae Rhizoma treated rats showed a lower leukocyte count(P<0.05) lymphocyte, neutrophil percentage, SHI(p<0.05), IFN-gamma and IL-4(p<0.05) in treated rats. Conversely, macrophage percentages went higher(p<0.05) in treated rats. Conclusion : This study supports a role for Fritillariae Rhizoma in reducing the maintaining inflammatory cells and cytokines in rats with bleomycin-induced lung fibrosis and in the reduction of fibrosis tissues. Further research is needed in order to develop an effective treatment for lung fibrosis.

        Backgrounds and Objectives: Asthma is considered to be an inflammatory disease characterized by airway hyperresponsiveness and Pulmonary eosinophilia. And it is known the structure and function of IL-5, its receptor and the mechnism IL-5 triggered eosinophil accumulation and inflammaion of the airways. At this point of view, we assume which oriental materia medics can the splenocyte inhibit from secreting the IL-S in vitro. Material and Methosds: We used the splenocyte of mouse 8 weeks after its birth, and then cnltivated those into the 2 experimental groups and control group for 48 hours. The culture medium of experimental groups were made of $1{\mu}g/ml,\;10{\mu}g/ml$, oriental materia medics, representative. And the culture media of control group was given no oriental materia medica. Then, we assayed the quantity of cytokine-expression by the Sandwich ELISA. The quantifies of cytokine-expression of the experimental groups were compared with that of the control group which was standardized These method were used for the all of oriental materia medica treated. Results: In this study, we demonstrated that 12 oriental materia medica that inhibit the splenocyte from secreting the IL-5 in both $1{\mu}g/ml,\;and\;10{\mu}g/ml$ culture media. Those were Equiseti Herbs, Sophorae Subprostratae Radix, Moutan Radicis Cortex. Trichosanthis Radix, Buddleiae Flos. Cyperi Rhizoma. Benincasae Semen, Armeniacae Semen. Zedoariae Rhizoma, Astragali Semen, Dolichoris Semen. Lilii Bulbus, Asparagi Radix, Atractylodes Rhizoma White, Polygonati Officinallis Rhizoma. Conculusions: These findinga indicate that some oriental materia medica, specially Antipyretics, Herbs for Resolving Phlegm, Relieving Cough and Calming Wheezing and Herbs for Tonifring and Invigorating effects inhibit the splenocyte from secreting the IL-5. And further study experimented in vivo is needed for treating IL-5-driven inflammatory disease including asthma.

        Objectives: We aimed to identify. the effect of Jeongcheon-tang(定喘湯) and Cheongsangboha-tang(淸上補下湯) on the transcriptional activities of cytokine IL-4, IL-5, IL-6 and IL-10 involved in asthma model. Materials and Methods: RBL-2H3 cell lines were used. Cells were stimulated with calcium inophore($2{\mu}M$ : Sample group 1, $4{\mu}M$ : Sample group 2) for maximal gene expression. After 3rd treatment of samples and incubation(per 24hours), total cellular RNAs were collected using Trizol solution method. Then transcriptional activities of IL-4, IL-5, IL-6 and IL-10 were measured by RT-PCR with electrophoresis. Results: In IL-4 study, Jeongcheon-tang treated group showed 82.76%(Sample group 1) of transcriptional activities compared to the control group and Cheongsangboha-tang treated groups showed 85.77% (Sample group 1), 89.42% (Sample group 2) of transcriptional activities compared to the control groups. In IL-5 study, Jeongcheon-tang treated groups showed 88.24%(Sample group 1), 98.83%(Sample group 2) of transcriptional activities compared to the control groups and Cheongsangboha-tang treated group showed 73.66%(Sample group 2) of transcriptional activities compared to the control group. In IL-6 study, Jeongcheon-tang treated group showed 92.95%(Sample group 2) of transcriptional activities compared to the control group and Cheongsangboha-tang treated group showed n.40%(Sample group 2) of transcriptional activities compared to the control group. In IL-10 study, Jeongcheon-tang treated group showed 118.46% (Sample group 2) of transcriptional activities compared to the control group. Conclusions: This study shows that Jeongcheon-tang has the inhibitory effect on the transcription of IL-4, IL-5, IL-6 gene expression and the increasing effect on the transcription of IL-10 gene expression, and Cheongsangboha-tang has the inhibitory effect on the transcription of IL4, IL-5 and IL-6 gene expression in RBL-2H3 cell lines. Advanced studies are required to investigate the mechanisms of inhibition or increase by herbal medicine in asthma model.

        창출(蒼朮)이 천식 관련 Th1/Th2 세포 분비 cytokine에 미치는 영향

        이정우,이형구,정희재,Lee, Jeong-Woo,Rhee, Hyung-Koo,Jung, Hee-Jae 대한한방내과학회 2007 大韓韓方內科學會誌 Vol.28 No.4

        Background and Objective : Atractylodes japonica (AJ) is a commonly-used herbal medicine in Asian countries such as Korea, China and Japan. The present study was designated to evaluate the direct effects of AJ on helper T cell activities and on Th1/Th2 lineage development in vitro. Materials and Methods : Spleen cells from 8-week BALB/c mice were cultured in CR extracts containing medium without activation for 24 hours and with activation for 48 hours. CD4+ T cells were isolated and analyzed for mRNA expression levels of INF-$\gamma$, IL-4, T-bet and GATA-3 by RT-PCR and secretion cytokines levels of INF-$\gamma$, IL-2, IL-4, IL-5 and IL-10 by ELISA. Results : The results demonstrated that AJ had no mitogenic effects on unstimulated CD4+ T cells, but augmented CD4+T-cell proliferation upon activation with anti-CD3/anti-CD28 antibodies in a dose-dependent manner. AJ treatment significantly increased CD4+ T cell population and IFN-$\gamma$ expression was significantly enhanced, while IL-4 expression significantly decreased. In addition, in vitro Th1/Th2 polarization experiments revealed that AJ enhanced IFN-$\gamma$ secretion in Th1 cells, but reduced the IL-4 in Th2 cells in dose-dependent manner. Conclusion : These results suggest that AJ treatment could be a desirable alternative therapy for the prevention or correction of Th2 dominant pathological disorders, such as allergy and asthma.
