      • Glucocorticoid-induced tumor necrosis factor receptor–related protein co-stimulation facilitates tumor regression by inducing IL-9–producing helper T cells

        Kim, Il-Kyu,Kim, Byung-Seok,Koh, Choong-Hyun,Seok, Jae-Won,Park, Jun-Seok,Shin, Kwang-Soo,Bae, Eun-Ah,Lee, Ga-Eun,Jeon, Hyewon,Cho, Jaebeom,Jung, Yujin,Han, Daehee,Kwon, Byoung S,Lee, Ho-Young,Chung, Nature Publishing Group, a division of Macmillan P 2015 Nature medicine Vol.21 No.9

        <P>T cell stimulation via glucocorticoid-induced tumor necrosis factor receptor (TNFR)-related protein (GITR) elicits antitumor activity in various tumor models; however, the underlying mechanism of action remains unclear. Here we demonstrate a crucial role for interleukin (IL)-9 in antitumor immunity generated by the GITR agonistic antibody DTA-1. IL-4 receptor knockout (Il4ra(-/-)) mice, which have reduced expression of IL-9, were resistant to tumor growth inhibition by DTA-1. Notably, neutralization of IL-9 considerably impaired tumor rejection induced by DTA-1. In particular, DTA-1-induced IL-9 promoted tumor-specific cytotoxic T lymphocyte (CTL) responses by enhancing the function of dendritic cells in vivo. Furthermore, GITR signaling enhanced the differentiation of IL-9-producing CD4(+) T-helper (T(H)9) cells in a TNFR-associated factor 6 (TRAF6)- and NF-kappa B-dependent manner and inhibited the generation of induced regulatory T cells in vitro. Our findings demonstrate that GITR co-stimulation mediates antitumor immunity by promoting T(H)9 cell differentiation and enhancing CTL responses and thus provide a mechanism of action for GITR agonist-mediated cancer immunotherapies.</P>

      • 혈소판 응집 억제제의 효과 측정법에 대한 고찰과 지원자에서 Triflusal의 혈소판 응집 억제능 평가

        이병요,장힘찬,백인환,윤휘열,권광일 충남대학교 약학대학 의약품개발연구소 2010 藥學論文集 Vol.25 No.-

        The anti-platelet agent is a member of a class of pharmaceuticals that decreases platelet aggregation and inhibits thrombus formation. They are effective in the arterial circulation and widely used in primary and secondary prevention of thrombotic cerebrovascular or cardiovascular disease. As a method for estimating the effects of anti-platelet agent, platelet aggregation was conventionally measured using the optical method or the impedance method. Several alternate methods currently in development or recently developed were considered, including luminescence method, flow cytometry, laser-light scattering method, and Verify Now-P2Y12 assay. Principles, advantages, and disadvantages of the optical method, impedance method, and the other alternate platelet aggregation methods were discussed in this report. 15 human volunteers were recruited for the evaluation of the efficacy of triflusal using the optical method. After the oral administration of a single dose of 900mg, 15 subjects received eight doses administered at 24-hour intervals of 600mg triflusal. Using platelet rich-plasma from above subjects, we performed baseline platelet aggregation test induced by adenosine diphosphate(ADP), collagen, and arachidonic acid. The results of platelet aggregation test after triflusal administration were compared with the baseline study. Triflusal significantly inhibited platelet aggregation induced by ADP (33.0±21.3%) and arachidonic acid (99.1±1.2%), respectively. Therefore, we concluded that anti-platelet aggregation effect of triflusal can be studied successfully with the optical method. Each of the platelet aggregation methods has value for evaluating the effects by various mechanisms of the anti-platelet agents. The ideal method for estimating the platelet aggregation as it relates to safety and efficacy in patients treated with anti-platelet agents will need to be determined in clinical trials.

      • 황련해독탕 및 귀비탕의 발효 전후 혈소판 응집 억제 효과에 대한 비교 연구

        송병정,이수진,권광일 충남대학교 약학대학 의약품개발연구소 2012 藥學論文集 Vol.27 No.-

        Recently interest of fermented oriental medicines is increasing for the purpose of disease prevention. Hwangryunghaedok-tang (HR) and Guibi-tang (GB) are widely used oriental medicines in Korea. HR and GB are well known for anti-inflammatory and anti-stress effect. Glycosides in herbal medicines are transformed to aglycone via fermentation. The fermented medicines are absorbed more and have less individual variation. In this study, HR and GB were compared before and after fermentation by anti-platelet aggregation effect. HR and GB were fermented by various lactobacillus species. The anti-platelet aggregation effect of HR and GB were measured using aggregometer by optical method. Collagen (4 μg/mL) was used as a inducer of platelet aggregation. After measuring anti-platelet aggregation effect, we analysed the data using WinnonlinⓇ program to fit simple Emax model. Then Emax and EC50 values were estimated. In results, GB had little antiplatelet effects. Emax of 5 GB samples (127, 164, 402, 442, 3163) were estimated near zero and others (129, 144, 166, 693, 744) had high EC50 values (> 1500 μg/mL). In contrast with GB, HR had antiplatelet effects. HR which was fermented by Lactobacillus casei and Lactobacillus plantarum (HR-127,HR-144) were most effective sample. Emax and EC50 of HR-127 and HR-144 was 99.99%, 174.73 μg/mL and 100.00% 160.48 μg/mL, respectively. These results indicated that Guibi-tang was inappropriate as anti-platelet aggregation agent and Hwangryunhaedok-tang would be more effective after fermentation as anti-platelet aggregation agent, warranting further study.

      • 초·중·고 학생들의 과학 지식 성취 수준 추이 분석을 위한 종단적 연구

        권재술,최병순,권치순,양일호,이경호,김지나 한국교원대학교 과학교육연구소 1999 청람과학교육연구논총 Vol.9 No.1

        학생의 과학 지식 성취도에 대한 장기간의 경향성은 과학 교육 정책의 효율성을 점검하는데 매우 중요한 요인이다. 그러나 지금까지 우리 나라 학생들의 학업 성취도의 경향성을 이해해보려는 진지한 노력이 현실적으로 거의 없었다. 최근까지 한국교원대학교 과학교육연구소에서는 전국에 있는 초·중·고 학생들을 대상으로 학생들의 과학 지식 성취도를 알아보기 위한 연구를 진행시켜왔다. 연구의 첫 단계에서는 평가 문항을 개발하였다. 두 번째 단계에서는 개발된 문항을 전국적으로 투입하고 그 결과를 수집하여 2년간의 변화를 분석하는 것으로써, 이 논문은 두 번째 단계에 관한 내용을 담고있다. 이 연구에서는 권재술 등(1998)이 개발한 국가 수준의 과학 지식 평가 도구를 일부 수정하여 사용하였다. 1997년에는 전국적으로 8,766명의 학생을, 1999년에는 4,398명의 학생을 조사 대상으로 하였다. 조사 대상은 지역별, 성별 등을 고려하여 우리 나라 전체 학생의 모집단을 대표할 수 있는 표본으로 선정되었다. 연구 결과, 2년 동안 초·중·고 학생들의 과학 지식 성취 수준의 서로 다른 변화를 확인할 수 있었다. 초등학생의 경우는 성취도가 감소하였으나, 고등학생의 경우는 증가하였고 중학생의 경우는 두 시기에 의미 있는 차이가 없었다. 과학 지식 영역의 하위 영역별 분석 결과를 보면, 초등학생의 경우 개념 체계에 대한 지식 수준을 유의미하게 향상되었으나, 사실과 원리에 관한 지식 수준은 낮아졌다. 반면 고등학생의 경우는 지식 수준이 향상되었으며 특히, 사실 영역에서 크게 향상 되었다. 연구에서는 이 자료를 성별, 지역별, 행동 목표 수준 그리고 검사 문항의 상황 등으로도 나누어서 분석하였다. 한국교원대학교 과학교육연구소에서 개발한 과학 성취 수준 점검 시스템은 국가 수준에서 학생들의 과학성취도를 점검하는데 효과적인 도구가 될 것이다. The long term trend of studensts' science achievement is a very important factor to check the effectiveness of science educational policy. However, up to date no such effort to understand the trend of Korean students' science achievement has been put into action. Recently, the Science Education Center in Korea National University of Education has been attempted to collect nation wide data for students' science achievement. The first part of the effort was to develop item pools. This study was the second part to collect nation wide data and to check any change during the two year time interval. In this study, the item pools developed by Kwon et. al.(1998) were used with some modification. The data were collected two times; February 1997 and March 1999. The subjects collected nationally were 8,766 students in 1997 and were 4,398 in 1999. The subjects were collected randomly but stratified by region and sex. As the results, the trends of achievement change during the two years were different from elementary to high school. The achievement scores were decreased in elementary schools and increased in high school. In case of middle schools, the change was not significant. However, even in elementary schools the knowledge on theory was increased significantly while knowledge on facts and principles were decreased. In contrast, the knowledge on fact showed the most increase in high schools. In this study, the data were analysed in light of region, sex, behavioral objective levels(ability) and context of test items. The science achievement monitoring system developed by the Science Education Center in Korea National University of Education can be an effective tool for monitoring students' achievement on the national level.
