  • This research investigates the effect of the Chaenomelis fructus(CMF) on Alzheimer's disease. Specifically, the effects of the CMF extract on (1) >$IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ mRNA of PC-12 cells treated with LPS; (2) amyloid precursor proteins(APP), acetylcholinesterase(AChE), and glial fibrillary acidic protein(GFAP) mRNA of PC-12 cells treated with CT-105; (3) the AChE activity and the APP production of PC-12 cell treated with CT-105; (4) the behavior of AD mice with ${\beta}A$; (5) expression of $IL-1{\beta}$, $TNF-{\alpha}$, MDA, $IL-1{\beta}$ mRNA, $TNF-{\alpha}$ mRNA, and ROS; (6) the infarction area of the hippocampus, and brain tissue injury in Alzheimer's diseased mice induced with ${\beta}A$ were investigated. The results were summarized as follows; 1. The CMF extract suppressed the expression of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ mRNA in THP-1 cells treated with LPS. 2. The CMF extract suppressed the expression of APP, AChE, and GFAP mRNA in PC-12 cells treated with CT-105. 3. The CMF extract suppressed the AChE activity, and the production of APP significantly in PC-12 cells treated with CT-105. 4. A significant inhibitory effect on the memory deficit was shown on the CMF extract group of the mice with Alzheimer's disease induced by ${\beta}A$ in the Morris water maze experiment, which measured stop-through latency, and distance movement-through latency. 5. The CMF extract suppressed the over-expression of $IL-1{\beta}$ protein, $TNF-{\alpha}$ protein, MDA, $IL-1{\beta}$ protein, mRNA, $TNF-{\alpha}$ mRNA, CD68/GFAP, and ROS in the mice with Alzheimer's disease induced by ${\beta}A$. 6. The CMF extract reduced the infarction area of hippocampus, and controlled the injury of brain tissue in the mice with Alzheimer’s disease induced by ${\beta}A$. These results suggest that the CMF extract may be effective for the treatment of Alzheimer’s disease. Investigation into the clinical use of the CMF extract for Alzheimer's disease is suggested for future research.

  • Objectives: Betula Platyphylla(BP) has been used as a analgesic, anti-microbial, anti-oxidant drug in Eastern Asia. However, it is still unknown whether BP ethanol extract could exhibit the inhibitory activities against ultraviolet B(UVB)-induced skin injury on human keratinocytes, HaCaT cells. This study was aimed to investigate the protective activity of BP ethanol extract on UVB-irradiated skin injury in HaCaT cells. Methods: The skin injury model of HaCaT cells was established under UVB stimulation. HaCaT keratinocyte cells were pre-treated with BP ethanol extract for 1 h, and then stimulated with UVB. Then, the cells were harvested to measure the cell viability, production of reactive oxygen species(ROS), pro-inflammatory cytokines such as interleukin(IL) 1-beta, IL-6, and tumor necrosis factor(TNF)-𝛼, hyaluronidase, type 1 collagen, matrix metalloproteinase(MMP)s. In addition, we examined the mitogen activated protein kinases(MAPKs) and inhibitory kappa B alpha(I𝜅;-B𝛼) as inhibitory mechanisms of BP ethanol extract. Results: The treatment of BP ethanol extract inhibited the UVBinduced cell death and ROS production in HaCaT cells. BP ethanol extract treatment inhibited the UVB-induced increase of IL-1beta, IL-6, and TNF-𝛼. BP ethanol extract treatment inhibited the increase of hyaluronidase, MMP and decrease of collagen. BP ethanol extract treatment inhibited the activation of MAPKs and the degradation of I𝜅-B𝛼. Conclusions: Our result suggest that treatment of BP ethanol extract could inhibit the UVB-induced skin injury via deactivation of MAPKs and nuclear factor kappa B(NF-𝜅B) in HaCaT cells. This study could suggest that BP ethanol extract could be a beneficial agent to prevent skin damage or inflammation.

  • Yeonguemjiri-tang(連芩止痢湯, YGT) exhibits potent anti-inflammatory activity in widely intestine disease, but its mechanism undisclosed. To elucidate the molecular mechanisms of YGT on pharmacological and biochemical actions in inflammation, we examined the effect of YGT on pro-inflammatory mediators in phorbol 12-myristate 13-acetate (PMA) plus A23187-induced mast cell and lipopolysaccharide (LPS)-stimulated macrophages. The investigation focused on whether YGT inhibited pro-inflammatory cytokines such as interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in PMA plus A23187-induced HMC-1 cells and inflammatory madiators such as nitric oxide (NO), TNF-${\alpha}$, IL-6, iNOS, COX-2 in LPS-stimulated RAW 264.7 cells. We found that YGT inhibited LPS-induced NO, TNF-${\alpha}$ and IL-6 productions as well as the expressions of iNOS and COX-2. These results suggest that YGT has inhibitory effects on mast cell-mediated and macrophage-mediated inflammation.

  • This study was to evaluate the effect of Samjayangchin-tang (STYCT) on mouse Th1 and Th2 cells' differentiation and ovalbumin (OVA)-induced allergic inflammation. The proliferation of mouse CD4 T cells and the secretion of Th1/Th2 cytokines under the influence of STYCT extract were measured as well as the amount of ${\beta}-hexosaminidase$ in RBL-2H3 cells and the levels of $TNF-{\alpha}$ and IL-6 secretion in Raw264.7 cells. BALB/c mice were orally administered with STYCT extract and simultaneously inoculated with OVA to induce allergic reaction and measure the level of total IgE, OVA-specific IgE and the production of IFN- g, IL-4, IL-5 by the spleen cells. When mouse CD4 T cell were stimulated with anti-CO3 and anti-CD28 for 48 hours in various concentrations of STYCT extract, it decreased proliferation of CD4 cells. CD4 T cells under Th1/Th2 polarizing conditions for 3 days with STYCT resulted in mild decrease of IFN- g in Th1 cells and significant decrease of IL-4 in Th2 cells. STYCT extract had a dose-dependent inhibitory effect on antigen-induced release of ${\beta}-hexosaminidase$ in RBL-2H3 cells. Treatment of STYCT extract on LPS stimulated Raw 264.7 cells showed dose-dependent decrease in IL-6 production. Oral administration of STYCT extract on OVA-induced allergic mice showed an inhibitory effect on the levels of total serum IgE and OVA-specific IgE by 53% and 44%, respectively. Culture of spleen cells with OVA resulted in significant increase of IFN- g by 54% and significant decrease of IL-4 and IL-5 by 42%, and 29%, respectively. The results show that STYCT does not strongly induce mouse T cells to transform into Th1 or Th2 but it has an anti-allergic effect in vitro, and that it also corrects the unbalance between the reactions of Th cells in allergic diseases.

  • Objectives : The present study was carried out to investigate the effect of Trichosanthis Radix extract (TRE) on the proliferation and activation of eosinophils which were prepared from lung cells of asthma-induced mice by ovalbumin (OVA) treatment. Methods : C57BL/6 mouse was exposed to OVA three times a week for 6 weeks. The mouse lung tissues were dissected out, chopped and dossiciated with collagenase (1 $\mu$g/ml). Eosinophils were activated by rmIL-3/rmIL-5 co-treatments. The lung cells were treated with TRE, incubated for 48 hr at 37$^{\circ}C$, and analyzed by flow cytometer, ELISA and RT-PCR methods Results : To measure cytotoxicity, mouse lung fibroblast cells (mLFCs) were pretreated with various concentrations of TRE. TRE at 100 $\mu$g/ml, the highest concentration, examined did not have any cytotoxic effects on mLFCs. In FACS analysis, number of granulocyte/lymphocyte, CD3e-/CCR3+, CD3e+/CD69+, CD4+/CD8+ T cells in asthma-induced lung cells were significantly decreased by TRE treatment compared to the control group. But CD4+/CD25+ T cells were not examined significant change in lung cells treated with TRE. In ELISA analysis, production levels of IL-3, IL-5, IL-13 and histamine in asthma-induced lung cells, which were induced by rIL-3 plus rmIL-5 co-treatment, were significantly decreased by TRE treatment. Conclusions : The present data suggested that Trichosanthis Radix on the inhibition of parameters associated with asthma responses in eosinpophils, and thus implicate the possibility for the clinical application of Trichosanthis Radix.

  • The inhibitory effect of Chung-Jang-Hwan (C-mix) consisted of Geranium nepalense subsp. thunbergii, Saururus chinensis, and Rubus coreanus were investigated in dextran sulfate sodium (DSS)-induced colitic mice by microarray analysis. Treatment with Cmix improved colitic symptoms, including colon shortening and myeloperoxidase activity. Treatment with DSS alone upregulated the expression levels of inflammation-related genes, including IL-$1\beta$, IL-6, CCL2, CCL4, CCL5, CCL7, CCL8, CCL24, CXCL1, CXCL2, CXCL5, CXCL9 and CXCL10, and other colitis-related genes such as COX-2, PAP, MMP family, S100a8, S100a9 and DEFA1 in mice. However, treatment with C-mix inhibited the expression levels of inflammation-associated genes induced by DSS. The increased expression levels of COX-2 and IL-$1\beta$, representative inflammatory genes, were confirmed by a quantitative realtime polymerase chain reaction analysis. These results indicate that C-mix may ameliorate colitis by the inhibitory regulation of inflammation-associated genes.

  • Purpose : This study was carried out to investigate the effects of Gagamdokhwalgisang-Tang on the morphometric changes of femur, and on the hormones and cytokines associated with bone metabolism in overiectomized rats. Methods : Twenty-four female Sprague-Dawley rats were divided into sham operated group(normal) ovariectomized group(control), and treated with extract of GD group(treated). Each group was evaluated the changes of body weight at 0, 3, 6, 8 weeks after ovariectomy. Morphometric analysis(femur weight, femur/body weight ratio, femur ash weight femur ash/body weight ratio cross sectional area of compact bone and concellous bone of femur) and histopathological examination were performed at 8 weeks after ovariectomy. Estrogen, Alkaline Phosphatase(ALP) and cytokine(Tumor necrosis $factor-{\alpha}$, $Interleukin-l{\beta}$, Inerleukin-6) assay were performed at 8 weeks after ovariectomy. Results : 1. The body weight of control and treated group was significantly increased(p<<0.001) compared with the normal group at 8 weeks. 2. The femur weight and femur/body weight ratio of treated group were significantly increased(p<<0.05, p<<0.01) compared with the control group at 8 weeks. 3. The femur ash weight showed no significantly different changes, but femur ash/body weight ratio of treated group was significantly increased(p<<0.05) compared with the control group at 8 weeks. 4. In the cross sectional area of cancellous bone of femoral body, the treated group was significantly increased(p<<0.001) compared with the control group at 8 weeks. 5. The serum estrogen level of treated group showed no significantly different changes compared with the control group at 8 weeks. 6. The serum ALP activity of treated group was significantly decreased(p<<0.01) compared with the control group at 8 weeks. 7. The serum Tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ level of treated group was significantly decreased(p<<0.05) compared with the control group at 8 weeks. 8. The serum $Interleukin-l{\beta}(IL-1{\beta})$ level of treated group was significantly decreased(n<<0.001) compared with the control group at 8 weeks. 9. The serum Interleukin-6(IL-6) level of treated group was significantly decreased(P<<0.01)compared with the control group at 8 weeks. Conclusion : These results indicate that GD inhibits bone resorption in ovariectomized rats. And the major inhibitory mechanism may be related to the inhibitory effects of GD on the secretion of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 in the pathogenesis of osteoporosis in estrogen deficient rats.
