Objectives: This study was carried out to know the effects of Gwan-Jul-Bang-7 (hereafter referred to GJB-7) on the inhibition of arthritis induced by collagen on the mouse. Methods: To assess the effects of GJB-7 on mouse with arthritis induced by collagen II, we conducted several experiments such as analysis of cytotoxicity, hepatotoxicity, arthritis index, total cell number of draining lymph nodes and paw joints, value of immunocyte in PBMC (peripheral blood mononuclear cell), DLN (draining lymph node) and paw joint, measurement of cytokine and anti-collagen II, observation of the histological changes of joint. Results: 1. Cytotoxicity against HFC (human fibroblast cells) was not observed in any concentration and hepatotoxicity was not observed in the GJB-7 treated group. 2. The incidence of arthritis significantly decreased. 3. Total cell number of draining lymph nodes significantly increased and total cell number of paw joints significantly decreased. 4. The percentage of $CD8^+$ cells in PBMC (peripheral blood mononuclear cell) significantly increased. The percentage of $CD3^+/CD69^+$, and $CD3^+/CD49b^+$ cells in PBMC significantly decreased. 5. The percentage of $CD19^+,\;CD3^+$, and $CD4^+/CD25^+$ cells in DLN (draining lymph nodes) significantly increased. The percentage of $B220^+/CD23^+$ cells in DLN significantly decreased. 6. The percentage of $CD3^+,\;CD4^+$, and $CD11b^+/Gr-1^+$ cells in paw joints significantly decreased. 7. The production of TNF-$\alpha$, IL-6, and MCP-1 significantly decreased. 8. Anti-collagen II in serum significantly decreased. 9. With the hematoxylin and eosin stain, inflammation of joint decreased. Under Masson's trichrome stain, the cartilage destruction and synovial cell proliferation and the expression of collagen fibers decreased. Conclusions: Comparison of the results for this study showed that GJB-7 had immunomodulatory effects. So we expect that GJB-7 could be used as an effective drug for not only rheumatoid arthritis but also another auto-immune diseases.

Atopic dermatitis induced NC/Nga mice were used to investigate the efficacy of Hyunggaeyunkyotanggamibang(HYGB) on the recovery of dermatitic symptoms through its influence on the immune related factors. The results are as below: 1. HYGB treated group showed improvement of atopic dermatitis with naked eye observation, and significant decrease of dermatitis index was observed after 14 weeks. 2. HYGB treated group showed significant decrease of the ratio of CCR3+, B220+/IgE+, and CD11b+/Gr-1+ immune cells in dorsal skin by 41.7%, 21.5%, and 23.8%, respectively. 3. HYGB treated group showed an increase of CD19+ immune cells by 10.3% in PBMC, whereas CD3+, CD3+/CD69+, NKT+ immune cells were decreased by 4.3%, 42.9%, and 21.7%, respectively. 4. HYGB treated group showed an increase in the expression of IFN-$\gamma$ in the serum by 514.3%. However, the expressions of IL-4, IL-5, IL-6, IL-13, TNF-$\alpha$, MCP-1 and RANTES were decreased by 21.2%, 69.8%, 90.5%, 28.7%, 72.2%, 26.1%, and 19.9%, respectively. Also, the expression of IgE was decreased by 44.3%. 5. HYGB treated group showed a decrease of the expression of IL-4 and IL-5 by 43% and 44.3%. The results above indicated that HYGB clinically used for atopic dermatitis treatment has objective validity, and therefore can be provided as the basic data for EBM(Evidence based medicine) construction for anti-allergic and anti-inflammatory studies.

현재까지 국내에서 탐색된 카드뮴 축적 식물 종은 월동이 불가능한 식물이므로 본 연구에서는 겨울기간 동안 phytoremediation에 이용하기 위한 카드뮴 축적 식물종을 탐색하고자 하였다. 월동 가능한 카드뮴 축적 식물을 이용할 경우 시간적 효율성을 제고할 수 있기 때문이다. 식물종은 중부 이북지역에서 월동이 가능하다고 판단되는 초본류 중에서 40종을 우선 선별하고 이중 야생식물종자은행으로부터 분양 가능한 7종 (큰이삭풀, Bromus catharticus: 괭이밥, Oxalis corniculata: 김의털, Festuca rubra: 말냉이, Thiaspi arvense: 배초향, Agastache rugosa: 서울제비꽃, Viola seoulensis: 돌마타리, Patnnia rupestris)의 식물을 실험 대상으로 선정하였다. 7종의 식물은 파종하여 발아시킨 후 사경재배하였다. 양액은 Epstein 1/2 배액을 이용하였으며, 카드뮴은 저면관수로 배양액에 직접 처리하였다. 실험 결과 큰이삭풀과 말냉이는 지상부에 각각 112.35 및 $86.69mg\;kg^{-1}$의 카드뮴을 축적하였고, 이 중에서 큰이삭풀은 생육에 매우 양호하였으므로 겨울기간 동안 카드뮴 축적 식물로서의 활용성이 가장 높을 것으로 사료된다.

To examine the effects of HHCP on atopic dermatitis and its various immunopathologic parameters was induced by DNCB in NC/Nga mice and the animals were orally administrated with HHCP. We summarized the results obtained from serum levels of IgE and the numbers of various immune cells as follow. HHCP has no cytotoxic effects at the range of concentration (1-400 ${\mu}g$/ml) on fibroblast isolated from lung of BALB/c mice. HHCP significantly lowered the serum levels of IgE compared with control at 16 and 20 week. HHCP significantly reduced the number of CD19$^+$ cell in spleen and DLN, as well as the number of B220$^+$ /IgE$^+$ cell in DLN compared with control. HHCP significantly reduced the number of ${\alpha}$${\beta}$ TCR$^+$ in spleen and DLN, the number of CD8$^+$ in spleen compared with control, and also significantly reduced the number of CD3$^+$, CCR3, CD3$^+$/CD69$^+$, CD3/ CCR3, CD4$^+$, CD3$^+$/ CD4$^+$/CD45$^+$ cell in DLN. HHCP increased the number of NK$^+$ cells in spleen compared with control, in contrast significantly decreased the number of CD11c$^+$/ Classll$^+$ cell and CD11b$^+$/Gr-1$^+$ cell in DLN. Taken together, these results suggested that HHCP has suppressive effects on atopic dermatitis through the inhibition of IgE production and modulation of immune cell population in NC/Nga mice.

Lichen-forming fungi are known to have various biological activities, such as antioxidant, antimicrobial, antitumor, antiviral, anti-inflammation, and anti proliferative effects. However, the immunosuppressive effects of Bryoria sp. extract (BSE) have not previously been investigated. In this study, the inhibitory activity of BSE on the proliferation of $CD8^+$ T cells and the mixed lymphocytes reaction (MLR) was evaluated in vitro. BSE was non-toxic in spleen cells and suppressed the growth of splenocytes induced by anti-CD3. The suppressed cell population in spleen cells consisted of $CD8^+$ T cells and their proliferation was inhibited by the treatment with BSE. This extract significantly suppressed the IL-2 associated with T cell growth and $IFN-{\gamma}$ as the $CD8^+$ T cell marker. Furthermore, BSE reduced the expression of the IL-2 receptor alpha chain ($IL-2R{\alpha}$) on $CD8^+$ T cells and CD86 on dendritic cells by acting as antigen-presenting cells. Finally, the MLR produced by the co-culture of C57BL/6 and MMC-treated BALB/c was suppressed by BSE. IL-2, $IFN-{\gamma}$, and CD69 on $CD8^+$ T cells in MLR condition were inhibited by BSE. These results indicate that BSE inhibits the MLR via the suppression of $IL-2R{\alpha}$ expression in $CD8^+$ T cells. BSE has the potential to be developed as an anti-immunosuppression agent for organ transplants.

Background and Objectives: The antioxidant ebselen will be able to limit or prevent the ototoxicity arising from 2-hydroxypropyl-β-cyclodextrin (HPβCD). Niemann-Pick Type C (NPC) disease is a disorder of lysosomal storage manifested in sphingolipidosis. Recently, it was noted that experimental use of HPβCD could partially resolve the symptoms in both animals and human patients. Despite its desirable effect, HPβCD can induce hearing loss, which is the only major side effect noted to date. Understanding of the pathophysiology of hearing impairment after administration of HPβCD and further development of preventive methods are essential to reduce the ototoxic side effect. The mechanisms of HPβCD-induced ototoxicity remain unknown, but the resulting pathology bears some resemblance to other ototoxic agents, which involves oxidative stress pathways. To indirectly determine the involvement of oxidative stress in HPβCD-induced ototoxicity, we tested the efficacy of an antioxidant reagent, ebselen, on the extent of inner ear side effects caused by HPβCD. Materials and Methods: Ebselen was applied prior to administration of HPβCD in mice. Auditory brainstem response thresholds and otopathology were assessed one week later. Bilateral effects of the drug treatments also were examined. Results: HPβCD-alone resulted in bilateral, severe, and selective loss of outer hair cells from base to apex with an abrupt transition between lesions and intact areas. Ebselen co-treatment did not ameliorate HPβCD-induced hearing loss or alter the resulting histopathology. Conclusions: The results indirectly suggest that cochlear damage by HPβCD is unrelated to reactive oxygen species formation. However, further research into the mechanism(s) of HPβCD otopathology is necessary.
