환자의 긴급 상황에서 수혈 시 일부 수혈 전 검사를 수행하지 않는다. 수혈 후 항체 선별검사를 실시하여 용혈성 수혈 반응을 일으키는 비예기 항체의 실태를 조사를 비교평가하기 위해 국내·외에 보고된 공시자료를 포함하여 조사하였다. 2014~2016년 P병원에서 항체 선별 검사 68,602건과 항체 동정검사 528건을 선정하였다. 68,602건 중 1,198건(1.74%)이 양성이며 Rh계열 161건(30.49%), Lewis계열 67건(12.69%), 기타(Di (a)등) 28건(5.30%)으로 나타났다. Anti-E는 93건(17.61%), c는 13건(2.46%)이다. 국내·외 공시자료 중 국내 경우는 2007년 이전에는 Anti-E 196건(22.45%), Anti-Le(a) 82건(9.39%) Anti-E+c 60건(6.87%)으로 조사되었지만 2008년 이후에는 Anti-E 107건(17.12%), Anti-E+c 56건(8.96%), Anti-Di (a) 28건(4.48%)으로 조사되었다. 한편 다른 국내의 경우는 S병원(2012~2015년)에는 Anti-E, Anti-Le (a), Anti-E+c이며Anti-E+c이며 D병원(2016~2017년)에는 Anti-E, Anti-D Anti-E+c,Anti-E+c, Anti-C+e로 조사되었다. Saudi의 경우는 Anti-D, Anti-E, Anti-Jk (a)순이며, India 경우는 Anti-M, Anti-N, Anti-Le (a), Anti-D로 조사되었다. 권역별 외상센터 개설 전후시기에 응급수혈요청의 빈도 비교에서는 1.8배 이상이 증가한 것으로 조사되었다. 결론적으로 장기간의 항체분포로 효율성을 검증할 수는 없었지만 수혈의 안전성을 높이고 응급 수혈 상황에서 용혈성 수혈 부작용을 줄일 수 있는 대안을 위해 기초 정보를 제공하고 추가적인 검증연구가 필요할것으로 사료된다.

Aloe vera L.(Aloe barbadensis Miller) has been used for many centuries for various medical, cosmetic and neutraceutical purposes. The gel of A. vera was reported to exert numerous biological activities including wound healing, immunomodulatory, anti-cancer, anti-inflammatory, anti-bacterial, anti-viral, anti-diabetic, and anti-psoriasis activities. Acemannan, found predominantly in the inner leaf gel of A. vera, has been identified as the main active ingredient exerting diverse biological activities. In this review, we summarized the recent findings on the immunomodulatory activities of acemannan. Studies that used purified acemannan demonstrate that acemannan exerts immune-stimulating, anti-cancer, anti-viral, and hematopoiesis-increasing activities. In addition, it is being clear that most of these activities of acemannan are mediated primarily by activating professional antigen presenting cells such as macrophages and dendritic cells.

This study examined the characteristics of total consumers' anti-sites on on-line and their changes according to the establishment year of consumers' anti-sites, the activities and the evaluation of consumers' anti-sites and their differences according to the characteristics of consumers' anti-sites. Total 649 consumers' anti sites were analyzed for examining the characteristics of total consumers' anti-sites and 18 anti sites were selected for examining the activities and the evaluations of consumers' anti site. The anti sites were evaluated by the index of using in preceding research. The result showed that about 90% of total consumers' anti-site were not activated, only a few consumers participated even in the activated sites, most activity of the anti-site were operated only on on-line not off-line, over half of anti-sites targeted to the company in the type of the subject of anti-site, and the majority of the external shape of anti-site were cafe. On the change of characteristics according to the opening year, the proportion of cafe and the sites acting on both on-line and off-line were increased year by year. The number of anti-sites was decreased since 2005 and the proportion of highly activated sites was lowest in 2005. On the activity of anti-sites, the number of providing the information were more than the number of presenting the complaint among the bulletin writings. The number of the bulletin writing were more in highly activated sites than in low activated sites. most of highly activated sites were problem solving type compared to the low activated sites. The number of the bulletin writings in company anti-sites were the most among three type of subject of anti-site. The number of the bulletin writings in cafe type were more than in home-page type. On the evaluation of consumers' anti-sites, most of the sites didn't update the notices and provided incomplete information how consumers participated in the protesting movements. The highly activated sites functioned better in most parts in providing a information, connection with other consumer and site manager, management of the site.

With increasing of communication technology in cyber-space, the space of consumer complain behavior moved from off-line to on-line, so called anti-site. No researches, however, really have done how the anti-sites worked for promoting consumer rights through consumer complain behaviors in cyber space. The purpose of this research was to give some suggestions for activating anti-site for promoting consumer rights. For this purpose, questionnaire on-line survey was conducted from April, 12 to 24, 2004. And 143 samples, who were visiting anti-site during survey period, were selected. Main findings were as following: First, visitors had rather positive confidence with informations in anti-sites. Second, visitors thought that anti-sites were working rather well in implementing consumer movement by sharing their experiences, and by supporting complaining space in cyber. Visitors, however, thought that anti-sites were not working well as a space for companies, not by giving their attentions on consumers' complains. Third, the satisfaction level of visitors was found to be rather high in terms of informations in anti-sites, and to be rather low in terms of companies' attentions on anti-sites and management of anti-sites. Based on results, some suggestions of activating anti-site for promoting consumer rights were as following: First, visitors should not only get information, but support new and useful informations for others. And also it was suggested that visitors should join consumer movement through anti-site actively. Second, companies should pay attentions on anti-sites for their sake because anti-sites could give very useful information improving customer satisfaction, and finally reducing cost and increasing profit.

Purpose: Screening serologic tests are important tools for the diagnosis of celiac disease (CD). Immunoglobulin (Ig)G anti-deamidated gliadin peptide (anti-DGP) is a relatively new autoantibody thought to have good diagnostic accuracy, comparable to that of anti-tissue transglutaminase (anti-tTG) antibody. Methods: Pediatric patients (n=86) with a clinical suspicion of CD were included. Duodenal biopsy, anti-tTG, and IgG anti-DGP antibody tests were performed. The patients were divided into CD and control groups based on the pathological evaluation of duodenal biopsies. The diagnostic accuracy of serological tests was determined. Results: IgA anti-tTG and IgG anti-DGP antibodies were positive in 86.3% and 95.4% of patients, respectively. The sensitivity, specificity, and diagnostic accuracy of the IgA anti-tTG test were 86.3%, 50.0%, and 68.6%, respectively, and those of the IgG anti-DGP test were 95.4%, 85.7%, and 90.7%, respectively. The area under the receiver operating characteristic (ROC) curve was 0.84 (95% confidence interval [CI], 0.74-0.91) for IgA anti-tTG test and 0.93 (95% CI, 0.86-0.97) for IgG anti-DGP test. The comparison of IgA anti-tTG and IgG anti-DGP ROC curves showed a higher sensitivity and specificity of the IgG anti-DGP test. Conclusion: IgG anti-DGP is a reliable serological test for CD diagnosis in children. High tTG and DGP titers in the serum are suggestive of severe duodenal atrophy. The combined use of IgA anti-tTG and IgG anti-DGP tests for the initial screening of CD can improve diagnostic sensitivity.

Talipariti hamabo is a plant growing around salt marshes in the Lava Coast region of Jeju Island, Korea. In this study, the extract of T. hamabo leaves was investigated for the anti-inflammatory, anti-oxidative and anti-bacterial activities and their active constituents were identified. In the anti-inflammatory tests using lipopolysaccharide-stimulated RAW264.7 cells, the ethyl acetate (EtOAc) fraction inhibited the nitric oxide production without causing cell toxicity. Moreover, the EtOAc fraction reduced pro-inflammatory cytokines (tumor necrosis factor-α, interleukin-6) as well as prostaglandin E₂. In the anti-oxidative studies with DPPH and ABTS⁺ radicals, potent scavenging activities were observed in the EtOAc and n-butanol fractions. Upon the anti-bacterial tests using Staphylococcus epidermidis, EtOAc and n-butanol fractions exhibited good activities. Through the phytochemical studies on EtOAc fraction, three components were isolated by repeated column chromatography; oleic acid (1), p-hydroxyphenethyl-trans-ferulate (2), nicotiflorine (3). Based on these results, the extract of T. hamabo leaves can be developed as natural resources for cosmetic applications.
