HIV감염자는 질병의 진전에 무관하게 감염 후의 경과시기에 따라서 CD4 T림프세포등 각종 면역상태를 나타내는 표지가 변한다. 따라서 HIV감염자의 질병진전을 예보하기 위하여서는 정기적으로 CD4등 각종표지를 측정하여 감염자의 질병상태를 monitoring하게 된다. 그러나 이러한 수치를 감염자관리에 적용하기 위하여서는 우리나라 일반인의 정상치를 파악하여 이를 지표로 해야하므로 국내정상인의 각종면역치에 대한 조사가 요구된다. 현재의 기준으로는 500이하로 떨어질 때에는 예방차원에서 AZT를 복용하게 되며 200이하로 떨어지면 질병의 유무에 관계없이 환자로 관리하게 된다. 본 연구에서는 한국인 185명의 감염자와 140명의 비감염자에 대하여 장기적으로 CD4 및 CD8T 림프세포와 CD4/CD8비를 측정하였다. 시험은 Flow cytometer(Facstar)를 이용하여 각각의 CD 분자에 대한 모노크로날 항체를 이용하여 2중혈광색소염색방법으로 측정하였다. HIV감염자의 CD4-T림프세포 절대수 및 백분율은 각각 462 및 18.2%이었는 반면, CD8의 수치는 1,170 및 47.0%이었다. 또한 CD4/CD8비는 0.43이었다. 이와는 대조적으로 비감염자의 경우, 한국인의 CD4의 평균 세포수는 886, 백분율은 32.9%이었으며, CD8 세포수는 730, 백분율은 26.8 그리고 CD4/CD8비는 1.31이었다. 외국인과 한국인과의 면역지표수치를 비교하였을 때에 CD4세포수와 백분율, CD8의 백분율에서는 현저한 차이가 없었으나 외국인 비감염자의 경우 CD4백분율이 43.6%, CD8 T림프세포의 절대수가 560으로 한국인과 약간의 차이가 있었다. 따라서 HIV감염자관리를 위한 면역지표측정시험에서의 각종수치의 정확한 해석을 위하여서는 한국인 비감염자수치를 고려해야할 것으로 판단된다. Several studies showed that the immunological factors such as CD4+ cell number, CD4%, CD 8+cell number and CD4/CD8 ratio and the serological factors such as β²-microglobulin(β²-MG), neopterin, soluble CD4, and soluble CD8 are related to the risk of development of AIDS. Especially, the CD4+ cell counts have been used to monitor progresson of HIV disease, to stratify, and to follow patients in clinical trials. Recently, the Centers for Disease Control and Prevention(CDCP) in USA has made the CD4+ cell count as a part of the classification of HIV disease. It is composed of 3 categories such as 1, 2, and 3 which asr ≥ 500/㎣, 200/㎣ ≥ and < 500/㎣, and < 200/㎣, respectively. In this study, to estimate the differences of immunological factors between HIV-infected and normal human groups in Korea, CD4+ T and CD8+ T cells, and the CD4/CD8 ratio were measured in 185 HIV-infected subjects and 140 healthy adult subjects. The lymphocyte subsets such as CD4+ T and CD8+ T were analysed by flow cytometer(FACStar) with two-color immunofluorescent stain using monoclonal antibodies such as anti-CD4 and anti-CD8 antibodies. The absolute numbers and percentages of CD4+ T and CD8+ T and the CD4/CD8 ratio of HIV infected persons were 462±277/㎣, 18.2±7.7%, 1,170±534/㎣, 47.0±10.6% and 0,43±0.26 whereas those of uninfected persons were 886±299/㎣, 32.9±7.0%, 730±259/㎣, 26.8±6.4% and 1.31±0.46(P<0.01). In addition, estimating the reference values of peripheral blood lymphocyte subsets of Korean, the absolute numbers and percentages of CD4+ T and CD8+ T and the CD4/CD8 ratio of 140 healthy adults persons were measured and compared with those of foreigners. The reference ranges of CD4+ T cells, CD8+ T cells, CD4%, CD8%, and the CD4/CD8 ratio and 1.31±0.46, respectively. The significant differences were not observed when compared with those of foreigners. However a little difference was observed in the percentages of CD4+ T and the absolute numbers of CD8+ T between the normal values of Korean and those of foreigners were 43.6±8.9%, 560±230/㎣. This result can also be useful as a basic data for the treatment and surveillance of HIV-infected patients in Korea.

Objectives: Despite the importance of human immunodeficiency virus(HIV) transmission through heterosexual contact, the features of heterosexual transmission has not been well studied in Korea. So we conducted a cross sectional study to determine the transmission rates in married couples and assess risk factors for male to female heterosexual transmission of HIV. Methods: 169 HIV-infected males and their female sex partners were recruited from 1985 to tune 1998. We examined female sex partner's HIV infection status and interviewed male index partners and their female sex partners about demographic characteristics and sexual practices. We analysed heterosexual transmission rate by epidemiologic characteristics, disease status and sexual practices. And we assessed risk factors for HIV infection by univariate and multivariate analysis. Results: 30 female sex partners were infected at enrollment, yielding an transmission rate of 17.8%. Among couples who had used condoms consistently, none of the female sex partners was infected with HIV. In univariate analysis the significant risk factors were full blown AIDS status (OR=4.1, 95% CI: 1.49-11.43) and low CD4 T cell count of index partners at enrollment (OR=7.8, 95% CI: 2.19-27.80). In multivariate analysis HIV-1 RNA levels was significant risk factor when adjusted by CD4 T cell courts and mean sexual contacts per month (OR=19.2, 95% CI: 1.03-357.59) Conclusion: The risk of male to female heterosexual transmission increased with advanced stages of HIV infection in the index male partners.

최근에 많은 정부출연 연구기관과 정보유통서비스 기관들이 ISO 9001 품질경영시스템을 도입하여 그들 조직의 업무 수행도를 향상시키는데 대한 관심이 두드러지게 증가하고 있는 실정이다. 하지만 도입시에 조직의 특성 및 현황을 제대로 반영하지 않아서 시스템의 요구사항과 프로세스가 지향하는 목표화의 현실적 차이 때문에 ISO 9001 품질경영시스템 운영에 따른 효과를 제대로 누리지 못하고 있다. 이에 한국과학기술정보연구원(KISTI)은 프로세스 표준화를 통한 생산성 증대 및 조직의 경쟁력 증가를 위해 ISO 9001 시스템의 요구사항을 반영하기 위한 프로세스 분석을 통하여 표준시스템 지향적 프로세스를 도출하였다. 그 결과, KISTI는 2003년 11월 11일에 ISO 9001:2000 인증을 받았고, 품질경영 업무를 수행함으로서, 고객 만족도 증가, 업무의 효율성 증대 및 업무처리 시간 단축 등의 효과를 얻을 수 있었다. Recently, numerous government institutions and information service organizations have shown interests in employing ISO 9001 Quality Management System(QMS) to increase their organizational performances. However, due to the gap between the system requirements and the process oriented goals in reality, they have not been able to merit from the ISO 9001 QMS. So, Korea Institute of Science and Technology Information(KISTI) has been designed a process oriented system by incorporating the process analysis results into the existing ISO 9001 system requirements for enhancing organizational competitiveness and promoting productivity through a process standardization. As a result, KISTI has been ISO 9001:2000 certificate in November 11, 2003. And we obtain a improvement of customer satisfaction and efficiency of work, reduction of work processing time using KQMS

HPV-16형의 염기배열 변이는 지역적, 인종적으로 특징적인 차이가 있으며 특히 HPV-16형 E6/E7 유전자의 특정 염기서열변이는 자궁경부암 및 자궁상피내 신생종양물의 발생을 일으키는 고위험 요인으로 알려져 있다. 본 연구는 2007년 부산지역 유흥업소 종사여성으로 분리된 HPV-16형 19건을 대상으로 E6/E7 유전자 영역(nt 34-880)을 표적으로 지역적 염기서열 변이를 조사하였다. nucleotide 수준에서 HPV16형 E6 유전자는 T178G (n=11), T178A (n=1), T350G (n=4), A442C (n=2), A104T, A111G, C116T, G145T, T183G, C335T, G522C 등 11종의 변이주가 발견되었고, E7 유전자는 A647G (n=12), A645C, A777C, G663A, T732C, T760C, A775T, T789C, T795G 등 9종의 변이주가 발견되었다. 아미노산 수준에서는 HPV-16형 E6 단백질의 경우 D25E (n=12), L83V (n=4), E113D (n=2), M1L, Q3R, P5S, Q14H, D25N, I27R, H78Y, C140S 등 11종의 변이주를, HPV16형 E7 단백질의 경우 N29S (n=12), L28F, T72S 등 3종의 변이주를 관찰할 수 있었다. 본 연구 결과, 부산지역의 HPV-16형 E6/E7 우점 돌연변이주는 E6 D25E (75%), E7 N29S (78%)로 각각 나타났다. 앞으로 자궁경부암 환자 및 일반여성을 포함한 더 많은 모집단을 대상으로 HPV-16형 E6/E7의 intratypic variants를 비교 조사하여 실제 HPV-16형 E6/E7 어떤 변이주가 자궁경부암 유발 위험성과의 관련성은 더 많이 연구되어져야 할 것으로 사료된다. Recent studies have reported that the distribution of HPV-16 sequence variation differs geographically, and more specifically that HPV-16 E6/E7 intratypic variants might carry a high risk for development of ICC (invasive cervical cancer) and CIN (cervical intraepithelial neoplasia) in a given population. To investigate the genetic diversities of HPV-16 E6/E7 oncogene by region, we collected nineteen HPV-16 isolates from sexually high-risk women in Busan, and analyzed the HPV-16 E6/E7 coding regions (nt 34 to 880) with HPV-16 E6/E7 specific PCR amplification. At the nucleotide level, eleven variants of the E6 genes and nine variants of the E7 genes were identified as follows: E6 T178G (n=11), E6 T178A (n=1), E6 T350G (n=3), E6 A442C (n=2), E6 A104T, E6 A111G, E6 C116T, E6 G145T, E6 T183G, E6 C335T, E6 G522C and E7 A647G (n=12), E7 A645C, E7 A777C, E7 G663A, E7 T732C, E7 T760C, E7 A775T, E7 T789C and E7 T795G, respectively. At the amino acid level, the isolated HPV-16 E6 and E7 genes showed eleven E6 variants: E6 D25E (n=12), E6 L83V (n=4), E6 E113D (n=2), E6 M1L, E6 Q3R, E6 P5S, E6 Q14H, E6 D25N, E6 I27R, E6 H78Y, E6 C140S and three E7 variants: N29S (n=12), L28F, T72S. HPV16 E6 L83V, the dominant variant in the Caucasian population, showed relatively low frequencies in our study population. We elucidated that the dominant HPV-16 E6/E7 variants were HPV-16 E6 D25E (63.2%) and HPV-16 E7 N29S (63.2%), which were phylogenetically included in Asian lineage. Further study is needed to evaluate the risk of cervical cancer related HPV-16 E6/E7 intratypic variants in the Korean population.

부산지역의 유흥업소 종사여성을 대상으로 HPV DNA chip 시험을 통하여 HPV 유병율 및 유전자형 분포를 조사하였다. 총 660건의 자궁경부도찰 검체로부터 258건(양성율 39.1%)이 검출되었으며, 20대에서 가장 높은 유병율을 나타내었다. 양성자의 유전자형 분포는 고위험군 유전자형의 경우 HPV-16 (15.9%), -53 (10.2%), -58 (7.7%), -18 (5.2%)순이었고, 저위험군 유전자형의 경우 HPV-70 (10.4%), -6 (4.1%), -11 (2.0%)순이었다. 특이하게 고위험군 감염여성의 분포비 (62.0%)가 저위험군(14.7%) 및 고/저위험군 혼합감염(12.0%)보다 4배 가까이 높았다. 전체 양성자중 단일유형 감염자는 175건(67.8%)이고 혼합유형 감염자는 83건(32.2%)이었다. 본 연구 결과 밝혀진 부산지역 유흥업소 종사여성에서 많이 발견되는 HPV 유전자형 분포의 다양성은 국내 도입된 자궁경부암 예방백신의 효과 예측 및 국내 특성에 맞는 다가백신 개발의 기초 자료가 될 수 있을 것으로 사료된다. We tried to analyze the HPV prevalence and HPV genotypes of sexually high-risk women living in Busan, the biggest seaport of South Korea. Six hundred sixty women engaging in high-risk occupations participated in this study. The prevalence of HPV infection and HPV genotyping were determined with MyGene<SUP>®</SUP> HPVDNA chip, which consisted of 16 high-risk HPV genotypes (oncogenic genotypes) and 8 low-risk HPV genotypes. The overall prevalence of HPV infection in this study population was 39.1% (258/660) and the 20's showed the highest prevalence of HPV infection (51.5%). The dominant HPV genotypes including single or multiple HPV-infected women were resulted in HPV-16 (15.9%), -53 (10.2%), -58 (7.7%), -18 (5.2%) in case of high-risk HPV genotype and HPV-70 (10.4%), -6 (4.1%), -11 (2.0%) in case of low-risk HPV genotypes. Remarkably, the proportion of women infected with high-risk HPV genotypes (62.0%) was almost four times higher than those of women infected with low-risk HPV genotypes (14.7%) and high/low-risk HPV genotypes (12.0%). Among the 258 HPV-infected women, single infection was 175, double infection 66, triple infection 12, quadruple infection 4, quintuple infection 1, respectively. Our finding suggests that the introduction and development of effective HPV vaccines should consider the current status of HPV genotypic infection in South Korean women.

기혜영,최병선,서진종,김선희,김민지,김은선,박종태,정재근 대한감염학회 2009 감염과 화학요법 Vol.41 No.4

Background : The epidemic of human immunodeficiency virus (HIV) or sexually transmitted infections (STIs) is an important public health issue in the worldwide. Therefore, we investigated the trends of the seroprevalence of HIV and, syphilis and the gonorrhea positive rates in Gwangju from 2002 to 2006. Materials and Methods : The results of laboratory tests for HIV, syphilis and gonorrhea were collected from five public health centers and 19 hospitals in Gwangju. The number of tested patients from 2002 to 2006 was 348,202 cases for HIV, 80,115 cases for syphilis and, 103,548 cases for gonorrhea. Results : HIV/AIDS infections have rapidly increased at public health centers and hospitals. Especially, most of newly HIV-infected people were patients on ambulatory care/hospitalization, and they were also found via preoperation tests and according to the clinical symptoms. The gonorrhea positive rates have gradually decreased by year while the syphilis infection rates have slightly increased from 2002 to 2006. Conclusions : We have to determine the reasons why HIV and syphilis infections, but not gonorrhea, have increases simultaneously by the year. These results should be helpful to create a more effective STD prevention policy and the treatment guidelines for the people in Gwangju in the near future.
