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.

국내 Human Immunodeficiency Virus(HIV) 감염자와 정상인의 면역학적 표지인자 비교연구

신영오,류재천,최병선,박용근 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCINE 1995 Journal of biomedical laboratory sciences Vol.1 No.1

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. 본연구에서는 한국인 185명의 감염자와 140명의 비감염자에 대하여 정기적으로 CD4 및 CD8T 림프세포와 CD4/CD8비를 측정하였다. 시험은 Flow cytometer(Facstar)를 이용하여 각각의 CD 분자에 대한 모노크로날 항체를 이용하여 2중혈광색소염색방법으로 측정하였다. HIV감염자의 CD4-T림프세로 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 평균세포수는 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%, CD8+ 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 l.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 1.31t0.46, 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.

Novel histone deacetylase inhibitors CG05 and CG06 effectively reactivate latently infected HIV-1

Choi, Byeong-Sun,Lee, Hak Sung,Oh, You-Take,Hyun, Young-Lan,Ro, Sunggu,Kim, Sung Soon,Hong, Kee-Jong Lippincott Williams Wilkins, Inc. 2010 AIDS -LONDON- CURRENT SCIENCE THEN RAPID SCIENCE P Vol.24 No.4

Histone deacetylase plays an important role in HIV latency. Novel histone deacetylase inhibitors, CG05 and CG06, were evaluated for their roles in HIV latency using ACH2 cells. Both inhibitors were highly efficient in reactivation of provirus and exerted lesser toxicity compared with other known histone deacetylase inhibitors. Histone acetylation increased when proviruses were reactivated by the compounds. These new inhibitors may contribute to the reduction of the HIV reservoir when used in conjunction with highly active antiretroviral therapy.

High Frequencies of the CCR2b-64I and SDF1-3'A Mutations with HIV Infection in Koreans

Choi, Byeong-Sun,Cha, Seung-Hun,Kim, Sung Soon,Park, Yong-Keun,Lee, Joo-Shil The Korean Association of Immunobiologists 2002 Immune Network Vol.2 No.2

Background: Host genetic polymorphisms in the HIV-1 co-receptor CCR5 and CCR2b and SDF-1, ligand for co-receptor CXCR4, have been known to be associated with the resistance of HIV infection and/or the delayed disease progression in HIV-infected patients. Methods: We examined the frequencies of SDF1-3'A and CCR2b-64I alleles of 354 Koreans including 100 HIV-uninfected persons, 13 discordant spouses of HIV-infected persons, and 241 HIV-infected persons. The genotyping assays of SDF1 and CCR2b genes were carried out by polymerase chain reaction-restriction fragment length polymorphism. Results: The frequencies of CCR2b-64I and SDF1-3'A alleles in Koreans were very high compared with Caucasians and blacks. Observed frequencies of CCR2b-64I and SDF1-3'A allelic variants were 25.1% and 28.7%, respectively. The frequency of the CCR2b-64I allele in Koreans was 2~4 times higher than those of other ethnic groups with the exception of Asian. The frequencies of CCR2b-64I and SDF1-3'A genotypes did not show the significant difference between HIV-infected and uninfected Koreans. However, the prevalence of CCR2b-64I genotype of the LTNP group was about two times higher than that of the remainder group (P< 0.05). Four (45%) out of 9 LTNPs (long-term nonprogressors) showed having the SDF1-3'A allele and 7 (78%) out of 9 LTNPs carried the CCR2b-64I allele. 3 (33%) out of 9 LTNPs had both SDF1-3'A and CCR2b-64I alleles. But none of 5 RPs (rapid progressors) appeared to have both SDF1-3'A and CCR2b-64I alleles. Conclusion: The different genetic backgrounds in study populations may affect the disease progression and the AIDS epidemic in each country. Further studies need to define whether high frequencies of CCR2b-64I and SDF1-3'A allelic variants may affect the HIV disease progression.

CCR2b-64I Allelic Polymorphisms in Advanced HIV-Infected Koreans Accelerate Disease Progression

Choi, Byeong-Sun,Choi, Jang-Hoon,Kim, Sung Soon,Kee, Mee-Kyung,Lee, Joo-Shil MARY ANN LIEBERT INC PUBL 2007 AIDS RESEARCH AND HUMAN RETROVIRUSES Vol.23 No.6

<P>Genetic polymorphisms of chemokine genes and chemokine-receptor genes in HIV-infected patients have been associated with delayed progression of this disease. The allelic frequencies of these genetic variants also differ between ethnic groups. To investigate the effects of the SDF1 and CCR2b genotypes on disease progression, survival of 200 HIV-infected persons for whom at least four subsequent immunologic data items had been collected was analyzed. A genotyping assay of SDF1 and CCR2b genes was carried out using polymerase chain reaction-restriction fragment length polymorphism analyses. HIV-infected persons heterozygous for the SDF1-3'A or CCR2b-64I alleles were included in the survival analysis, but homozygotes were excluded because of a very small sample number. Neither the CCR2b-+/64I allele nor the SDF1-+/3'A allele, separately or in combination, had a significant impact on survival during the asymptomatic period of HIV infection. However, CCR2b-+/64I alleles were associated with accelerated disease progression during the advanced period of HIV infection. The survival time of HIV-infected people with CCR2b-+/64I and SDF1-+/+ genotypes was significantly shorter than those of the other groups (p < 0.01), but this effect was not apparent in persons with CCR2b-+/64I alleles and SDF1-+/3'A genotypes. These results suggest that the effect of CCR2b-64I polymorphisms on disease progression may differ according to the stage of HIV infection and interactions with other gene variants.</P>

This study was conducted to investigate the feeding fermented agro-industrial by-products on estimating the productivity and nutrient utilization of fattening black goats. Four experimental groups were set up with each of 6 animals for a 30 days feeding trial on growth performance and 12 black goats on nutrient digestibility were allocated to 4 groups of 3 animals each by latin-square design, control (offered concentrate and rice straw) and 3 treatment groups (offered fermentation feed and rice straw). Average daily gain (ADG) showed a significant high in control group, T3 was lower than other groups (p<0.05). DM and OM intake (㎏/head) were 718.8, 680.9 g and 634.2~699.2 g, 602.8~660.4 g for control and treatment groups, respectively. As increasing of rice bran content was decreased feed intake. Digestibility of DM and OM for control group were significantly higher than treatment groups (p<0.05), and T3 treatment group with 30% rice bran was the lowest among treatment groups. Nitrogen retention was significantly higher in control and T1 groups. Thus, these results showed that productivity and nutrient utilization were similar between fermentation feeds with agricultural by-products and commercial feeds. However, this study was suggested that it must contain less than 5.0% crude fat because of feed efficient was decreased by increasing of rice bran content. 본 연구는 농산부산물을 이용한 발효사료의 급여효과를 알아보기 위해 비육 흑염소의 생산성 및 영양소 이용률을 조사하였다. 증체조사를 위한 사양시험은 거세흑염소 24두를 이용하여 처리구당 6두씩 30일 수행하였고, 소화율시험은 거세흑염소 12두를 공시하여 처리구당 3두씩 라틴방각법으로 실시하여, 처리구는 대조구(배합사료 및 볏짚 급여구)와 3개의 시험구(발효사료와 볏짚 급여구)로 각각 배치하였다. 일당증체량은 대조구가 가장 높았고, T3구가 가장 낮았다(p<0.05). 1일 두당 건물섭취량과 유기물섭취량은 시판사료를 급여한 대조구가 각각 718.8과 680.9 g, 농산부산물 첨가구가 각각 634.2~699.2와 602.8~660.4 g으로 나타나 농산부산물 중 미강 첨가구가 높을수록 섭취량이 낮아지는 경향으로 나타났다. 건물과 유기물 소화율은 대조구가 농산부산물 첨가구보다 유의하게 높았고(p<0.05). 시험구간에는 미강을 30% 첨가한 T3구가 가장 낮았다(p<0.05). 질소 축적률은 대조구와 T1구가 유의하게 높았다. 따라서, 본 연구의 결과 농산부산물을 이용한 발효사료(T1과 T2구)는 시판사료를 급여한 대조구와 비교 시 증체는 86~90%, 건물소화율은 91.7~93.1%의 수준을 보였으며, 질소이용성은 대등한 수준을 보였다. 그러나 미강의 첨가 비율이 높아질수록 사료효율 저하가 우려되므로 조지방 함량을 5.0% 이하로 배합하는 것이 필요하다 판단된다.
