The purpose of this research is to examine the effects of Kamijihwang-tang(KJHT) on CD+4 T cells and CD8+ T cell ovalbumin (OVA)-induced asthmatic mice. C57BL/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (four a week) for asthma induction. Two experimental groups were treated with different concentrations of KJHT (400 mg/kg and 200 mg/kg) extract and cyclosporine A (10 mg/kg) for the later 8 weeks. At the end of the experiment, the mice lung, peripheral lymph node (PLN), and spleen were removed and CD4+ T cells and CD8 + T cells for analyzed by flow cytometer. Number of CD4+ T cells in lung, PLN, spleen of the KJHT group (400 mg/kg) were significantly decreased compared with that of control group. Number of CD8+ T cells in lung, PLN, spleen of the KJHT group (200 mg/kg) were significantly decreased compared with that of control group. The results of this study suggest that KJHT alleviated asthmatic hyperactivity through CD4+ and CD8+ T cells. Further study of relative cytokines is expected.

Objective : The purpose of this research is to examine the effects of Gleditsiae Spina (GS) extract on immune cells and cytokines in ovalbumin (OVA)-induced asthmatic mice. Methods : In vivo, C57BL/6 mice were sensitized and handicapped by OVA for 12 weeks. During this experiment, the one group was then treated with GS extract for the later 8 weeks (3 times per week) and analyzed by ELISA, flow cytometer and RT-PCR. Results : In vivo, there were significant decreases in eosinophils, IL-4, IL-5, IL-13, IgE in BALF (bronchoalveolar lavage fluid). However, $IFN-{\gamma}$ in BALF of GS group increased significantly, compared with that of control group. Additionally, the population of $CD3e^-/CCR3^+,\;CD69^+/CD3e^+,\;IgE^+/B220^+,\;CD11b^+/Gr-l^+$ cells in the GS group decreased. Conclusion : The results of this study support a role for GS as an effective treatment for asthma in its experimental success in significantly decreasing inflammation and asthma reactions, and in increasing $IFN-{\gamma}$, which helps prevent such reactions.

In this study, we were performed to elucidate the antioxidant and anticancer activity by leaves extracts from Acer tegmentosum (AT-L). In DPPH, ABTS radical scavenging activity, the AT-L revealed the high scavenging activity. Especially, the AT-L measured the highest ABTS radical scavenging activity, which is higher than ascorbic acid. The types of human cancer cells for evaluating the anticancer activity were colorectal cancer (SW480), prostate cancer (PC-3), breast cancer (MCF-7), pancreatic cancer (AsPC-1), lung cancer (A549) and liver cancer (HepG2). Human cancer cell viability was measured using MTT assay. Treatment of the AT-L decreased the cell viability and induced apoptosis in SW480 cells. These results suggest that extracts of the AT-L can be used as supplementary material for developing the natural antioxidant and anticancer drug for human cancer cells.

The purpose of this research was to investigate effects of Bambusae Caulis in Liquamen(BCL) on T-lymphocytes and peritoneal macrophages in mice. The apoptosis and subpopulation of T-lymphocytes were tested using a flow cytometer. The phagocytic activity of mouse peritoneal macrophage was tested using a luminometer. Nitric oxide production was tested using a Griess reagents. BCL induced T-lymphocytes apoptosis. BCL increased $T_H$ cells population and decreased $T_C$ cells population of T-lymphocyte, but did not affect splenocytes subpopulation. BCL increased nitric oxide production and phagocytic activity of peritoneal macrophage in mice. These results suggest that BCL regulates the immune system in consequence of an increase in helper T cell population and macrophages activation.

The purpose of this study was to compare the nutritional status and the immunocompetence of elderly women residing in urban and rural areas. Dietary food records and anthropometric measurements were used to evaluate the nutritional status of subjects. The immune function of subjects was assessed by total and differential white blood cell(WBC) counts. Total B and T Lymphocytes, and T cell subsets were quantified by flow-cytometer. Immunoglobulin G, A, and M concentrations were also measured as an index of humoral immunity. Elderly women in rural area showed a relatively lower dietary intake of total energy, protein, and iron than did urban elderly women. Total WBC, neutrophil counts, eosinophil counts, and the percentage of neutrophils among total leukocytes were significantly higher in urban elderly women than in rural women. Although the numbers of lymphocytes were not significantly different, the percentage of Lymphocytes among total leukocytes as greater in rural elderly women than in urban. Both groups did not show any significant differences in numbers of T cell subsets and NK cells. Immunoglobulin G, A, and M levels were not significantly different between the two groups, but the numbers of subjects placed under the deficient range of immunoglobulins were greater in rural than in urban elderly women. from the present study, it could be suggested that poor nutritional intake may selectively affect the number of immune cells, thereby influencing the immunocompetence of elderly women.

Objectives : We investigated the effects of Bojungikgi-tang (BJIGT) on P450 cytochrome enzyme and oxidative stress in the cells. Methods : We enrolled the HepG2 hepatocyte cell line to assess MTT assay, flow cytometer, and immunoblotting analysis. Expression of CYP450 was confirmed by immunoblotting analysis in the Huh7 cell line. Results : We determined that BJIKT markdely changed the expression of the CYP2C19, CYP2D6, and CYP2E1. Moreover, BJIKT inhibited the cell toxicity induced by arachidonic acid + iron treatment, as assessed by FACS analysis. BJIKT induced AMPK activation, which increased the phophorylation of ACC. Conclusions : This study verified the effects of BJIKT, on P450, ROS production, mitochondrial damage and AMPK signaling pathway, which might give us the scientific information about the traditional herbal prescription.

Streptococcus salivarius is a beneficial bacterium in oral cavity, and some strains of this bacterium are known to be probiotics. The purpose of this study was to investigate the anti-inflammatory effect and mechanism of S. salivarius G7 lipoteichoic acid (LTA) on lipopolysaccharide (LPS) and LTA of periodontopathogens. The surface molecules of S. salivarius G7 was extracted, and single- or co-treated on human monocytic cells with LPS and LTA of periodontopathogens. The induction of cytokine expression was evaluated by real-time PCR and ELISA. After labeling fluorescence on LPS and LTA of periodontopathogens, it was co-treated with S. salivarius LTA to the cell. The bound LPS and LTA were measured by a flow cytometer. Also, the biding assay of the LPS and LTA to CD14 and LPS binding protein (LBP) was performed. The surface molecules of S. salivarius G7 did not induce the expression of inflammatory cytokines, and S. salivarius G7 LTA inhibited the inflammatory cytokines induced by LPS and LTA of periodontopathogens. S. salivarius G7 LTA inhibited the binding of its LPS and LTA to cells. Also, S. salivarius G7 LTA blocked the binding of its LPS and LTA to CD14 and LBP. S. salivarius G7 has an inhibitory effect on inflammation induced by LPS or LTA of periodontopathogens, and may be a candidate probiotics for prevention of periodontitis.
