본 연구는 여성노인의 라인댄스 프로그램 참여에 따른 면역기능 및 염증변화의 특징을 규명하고자 수행되었다. 이를 위해, Y시에 거주하고 있는 60-70세 여성노인 18명을 선정하였으며, 12주간 라인댄스 프로그램에 참여한 운동군 9명과 동일한 기간 특별한 신체활동에 참여하지 않고 일상적인 생활을 해온 통제군 9명의 두 집단으로 무작위 선정하여 분류하였다. 대상자들의 면역기능 및 염증을 측정하여 자료를 수집하였으며, 자료분석은 SPSS 24.0을 이용하여 평균과 이원변량분석을 실시하였다. 그 결과 면역글로블린인 IgA은 증가하였으나 유의한 증가를 보이지 않았고 IgG(p<.05), IgM(p<.05)은 라인댄스 운동군에서 유의한 증가가 있었으나 통제군에서는 유의한 차이가 나타나지 않았다. 염증지표인CRP(p<.05)은 라인댄스 운동군에서 유의하게 감소하였고, 통제군에서는 유의한 차이가 없었다. 따라서 규칙적인 라인댄스 프로그램은 여성노인의 면역 향상 및 염증 감소에 매우 효과적인 운동프로그램이라 할 수 있으며, 염증을 감소시키고 면역기능 개선에 도움을 줄 수 있음을 보여주는 결과로, 향후 여성노인들의 건강유지와 만성질환 예방을 위해 적극적인 신체활동 프로그램 개발과 중재의 필요성을 시사한다.

Objectives : Sojadodamgangki-tang and its main components are traditional korean medicinal methods for treatment of cough, sputum and dyspnea. Using a respiratory inflammatory model, we intend to reveal the anti-inflammatory effect and its immune mechanism of Sojadodamgangki-tang. Methods : We used a papain-induced respiratory inflammatory mouse model. 8-week-old female BALB/C mice were divided into 3 groups as follows: the following groups: saline control group, papain treated group (vehicle), papain and Sojadodamgangki-tang(200 mg/kg) treated group (n=4). To evaluate the anti-inflammatory effect of Sojadodamgangki-tang extracts, inflammatory cell infiltration was measured in bronchoalveolar lavage fluid (BALF) and nasal lavage fluid (NALF). In addition, the effects of Sojadodamgangki-tang extracts on Th2 cell population in lung were determined by using flow cytometry. Results : Sojadodamgangki-tang extracts administration reduced inflammatory cell infiltration in BALF and NALF, especially of eosinophils. Furthermore, total immunogloblin (Ig)-E levels was reduced in BALF and serum by drug administration. Interestingly, Sojadodamgangki-tang extracts treatment also decreased the Th2 cell (CD4⁺GATA3⁺) population in lung. Conclusions : Our findings indicate Sojadodamgangki-tang extracts have anti-inflammatory effects by mediating Th2 cell and B cell activation.

국내에서 분리한 강독전염성후두기관염 바이러스 (ILTV)에 대한 세포융합방법에 의해 단크론성항채(MCA) 생산을 시도한 결과 총 8회의 세포융합을 통하여 총 1017개의 융합세포가 생산되었으며 그중 ILTV와 특이적으로 작용하늘 항체를 생산하는 3주의 Hybridoma를 작성하였다. 이 3주의 MCA는 모두 IgG형에 속하였으며 마우스 복강내접종하여 생산된 복수항체외 형광항체가는 $10^5$－$10^6$에 달하였고 약독 및 강독 ILTV에 차이가 없이 작용하였으며 중화능력은 인정되지 않았다. 이 MCA를 이용하여 간접형광항체법으로 인공감염계에서 ILTV 검출을 시도한 결과. 기관 및 안점막의 도말표본에서 감염후 10일 까지 진단이 가능하였으며 표준 양성혈청을 이용한 형광항체법이나 핵내봉입체 검출방법에 비해서 진단효율이 높았다.

To evaluate effect of CRSST on inhibiting the occurrence of arthritis, we performed the experiments including production of inflammatory cytokine and immunoglobin in collagen induced arthritis model. The results were obtained as follows. CRSST extract shows any cytotoxicity effect on mouse lung fibroblast cells at dose of 400 ㎍/㎖. CRSST group shows inhibitory effect on arthritis incidence than control group for six weeks. Arthritis index of CRSST group reduces from 4 weeks (75±17.4%) to 6 weeks (33.3±10.0%) compared with control group. In CRSST group, production of cytokines which shows suppressive effect on inflammation (IL-4, IL-10 ) are increased and which promotes inflammation (TNF-α, INF-γ) are decreased in blood. In CRSST group, production of immunogloblin (IgG2b, IgG3 and IgM) is reduced compared with control group, and rate of CD4+ and CD3+ T cell is lower in joint and higher in lymph node compared with control group. From above results it could be accepted that CRSST shows anti-arthritis effect via immune system especially through the controlling the inflammatory cytokines and immunoglobins. CRSST could be usefully applied for the prevention and treatment of RA. And also is expected to be clinically helpful on the treatment of RA through modification.

The immunosuppressive effects of safrole were studied in female BALB/c mouse. Mice were given 100,200and 400mg safrole/kg daily for 14days and evaluated on day 15. The day 4 immunogloblin-M antibody response to T-dependent antigen, sheep red blood cells (SRBC) was inhibited dose-dependently in all doses studied. In vitro antibody response to polyclonal antigen, lipopolysaccharide (LPS) by spleen cell suspensions from safrole-treated mice were also significantly inhibited. When safrole was treated for 14days to mice, and mitogen-induced proliferation of splenocytes were assayed on day 15, there were significant suppression of responses to B-cell mitogen, LPS and T-cell mitogen concanavalin A(Con A) at a dose of 400mg safrole/kg. Direct addition of safrole on the splenocyte culture also produced a dose dependent suppression on in vitro antibody response to LPS, and mitogen-induced lymphoproliferatin at doses of 100,200,400 and 800${\mu}M$ safrole. The role of metabolic activation in safrole-induced suppression of in vitro antibody response was studied using splenocyte-hepatocyte coculture system. The suppression of in vitro antibody respose to LPS by safrole was not altered when safrole were incubated in the splenocyte-hepatocyte system for 4hr as compared with direct addition of safrole in splenocytes culture. Neither the addition of salicylamide, sulfotransferase inhibitor, nor the addation of inorganic sulfate, sulfation cofactor to the splenocyte-hepatocyte coculture, altered the suppression of antibody response by safrole. These results suggest that the immunosuppression by safrole may not by produced by the reactive metabolites which are mediated in carcinogenesis of safrole.

This study aims to examine the effect of Genetically Modified ${\beta}$-Carotene Biofortified Rice rice developed by simultaneous expression technology in NAAS on biological immunity. Accordingly, this study added Genetically Modified ${\beta}$-Carotene Biofortified Rice 25, 50% and general rice 50% as control group into diet and provided rats with the prescribed feeds and then measured the contents of immunoglobulin and cytokine in blood. As a result, male and female IgM, IgE, male IgG1, female IgG2a and TNF-a, IL5 and IL12 showed no significant difference; male IgG2a tended to decrease dependently on the combined concentration of Genetically Modified ${\beta}$-Carotene Biofortified Rice; female IgG1 showed significance with control group, but its association with diet was not found. The higher the dietary mixing ratio, the more the male and female IFN-a and female IL-4 contents, regardless of rice variety, and it was found that female IL6 content decreased significantly, but its association with diet was not found. The risk of beta carotene-enriched rice into environment and human body has not been reported yet. The digestion of Genetically Modified ${\beta}$-Carotene Biofortified Rice can be seen as "safe" as this test result showed no big difference between general rice and Genetically Modified ${\beta}$-Carotene Biofortified Rice, and its usability is full of suggestions.

To investigate the effects of negative therapy at back meridian points on blood gas components and immune functions in male college students, this study was conducted on treatment types(abdomen group and back group) at three sampling times (before, post-2 wks and post-4 wks) by using $2{\times}3$ factoral design. Blood gas $components(pH,\;PCO_2,\;PO_2,\;HCO_3^-,\;O_2SAT,\;BE)$, red blood cell, hematocrit, hemoglobin, white blood cell and subsets(neutrophil, basophil, eosinophil. lymphocyte, monocyte), total T cells, helper T cells, suppressor T cells, Th/Ts ratio, total B cells, serum immunoglobulin levels (IgG, IgA, IgM, IgD, IgE), Cytokines(Interlukin$-1{\beta}$, -2, -4, 2 receptor, -6 and ${\gamma}$-interferon), NK cells were measured. Collected with data were analyzed statistically by repealed measured ANOVA. The pattern of change between two groups for hematocrit, hemoglobin, suppressor T cells, interleukin-6, ${\gamma}-interferon$, NK cells at post-2 weeks and BE, lymphocyte, basophil at post-4 weeks was significantly different(p<0.05) And also the pattern of change over time for ${HCO_3}^-$(2 wks vs 4 wks), WBC, neutrophil, lymphocyte(0 wks vs 2 wks and 2 wks vs 4 wks) was significantly different(p<0.05). In summary, these data suggest that negative therapy at back meridian points had an effect on blood gas components and immune functions in male college students because practicing negative therapy at back meridian points was not associated with changes of all blood gas components and immune factors but associated with changes of BE, hematocrit, hemoglobin, WBC. neutrophil, lymphocyte, interleukin-6. ${\gamma}-interferon$, NK cells.
