Background : Previous data have been reported that subtype B is prevalent in South Korea, but neither the extent nor the proportion of subtypes could be evaluated. This study was designed to analyze the distribution of HIV-1 subtypes, temporal instructions and transmission dynamics between epidemiological groups. Methods : 1,280 Koreans had been diagnosed as HIV seropositive during the period 1985 to 2000. Among them, 134 individuals were selected for this molecular epidemiological study. 134 DNAs were isolated from uncultured or cultured peripheral blood mononuclear cells. V3-V5 (0.7 kb) fragment of HIV-1 env gene was amplified by nested polymerase chain reaction and was sequenced. Results : HIV-1 isolates from thirty-seven homosexuals were all subtype B (100%). On the other hand, 66 isolates from 94 heterosexuals were subtype B (70%) and 28 were non B subtypes (30% : 13 A, 4 C, 2 D, 8 E , 1 G). Only subtype B strains were isolated from 73 males who were infected with HIV inside Korea while 16 B and 20 non B subtype strains were isolated from 36 males who were HIV infected outside of Korea. However, B and non B strains were isolated half and half from females who were infected inside Korea except one. Conclusion : The HIV-1 subtype B strains are prevalent in Korea from the early HIV infection until present in both homo and heterosexuals. Non B strains have been transmitted from men who were infected outside Korea to their spouses and casual partners. So, we need further study to monitor subtype B and non B HIV transmission in epidemiological groups of Korea, (Korean J Infect Dis 33:311∼318, 2001)

Purpose: This study was to apply head and neck massage to patients in intensive care unit and to inventigate the effect of that massage on sleep and state anxiety. Method: The subjects in this study were 27 patients who were admitted in medical intensive care unit. The study was performed from June thru September of 2005 on the One-group pretest-posttest design and the sleep, state anxiety of the subjects were measured before and after head and neck massage. For data analysis, paired t-test and Pearson correlation coefficient were utilized. Result: The first hypothesis that the subjects might have a better sleep after being exposed to head and neck massage was accepted. The second hypothesis that the subjects might feel less state anxiety afrer being exposed to head and neck massage was accepted. The third hypothesis that the sleep of the ICU patients maight be correlated to their anxiety was accepted, as there appeared correlation between their sleep and anxiety. Conclusion: Head and neck massage is identified as one of independent nursing interwentions to improve the sleep of ICU patients and ease their anxiety, and it is necessary to apply it to clinical practices.

Necrotizing pancreatitis develops in about 10-20% of patients with acute pancreatitis, and pancreatic abscesses develop in 3% of them. The mortality of pancreatic abscess has been reported up to 40% in one study. Recently, there are several reports that show good results with n on-surgical therapy, such as percutaneous drainage and endoscopic drainage, but if the non-surgical drainage fails, surgical therapy are recommended. However, there is no definite therapeutic method which is suggested yet so far after the failure of the surgical drainage. So we report the case in which we experienced successful treatment of pancreatic abscess by endoscopic removal of necrotic tissue through the gastrocystostomy, after the failure of the surgical debridement and internal drainage through gastrocystostomy.

연간 어획량으로 볼 때 오징어는 다른 어종 못지않게 중요한 종류이다. 오징어는 몸통뿐 아니라 내장과 간장 또한 이용가치가 매우 뛰어남에도 불구하고 그동안에는 사료용으로만 약간 사용되고 나머지는 대부분 폐기하였다. 본 연구에서는 이들 간장의 이용도를 넓힐수 있는 기초자료를 확보하고자 간장 중 일반성분과 지질 클래스의 변화를 월별로 조사하였다. 우선, 주문진항에서 4월에서 10월까지의 매월 한차례씩 살아있는 오징어를 구입하여 이들의 체중과 체장, 그리고 내장과 간장의 무게를 재고, 간장은 일반성분과 지질분석을 하였는데, 월별 체중 및 체장은 7월을 기점으로 여름철에 증가하며 체중도 같은 경향을 나타내었다. 그리고 간장의 무게도 체중의 증가와 비례하여 증가하였다. 비만도는 체장의 증가율에 비해 체중의 증가율이 높은 5월이 비만도가 가장 높았다. 같은 기간 중 일반성분의 변화를 보면, 수분은 대체로 감소하는 경향이고 단백질은 7월에서 9월 사이에 증가하는 경향을 보였다. 지질은 단백질과는 반대로 7월에서 9월 사이에 감소하는 경향을 보였으며, 회분은 매월 일정한 값을 나타내었다. 이러한 결과로 어체의 성장이 활발한 여름철에 단백질의 양이 증가하고 반면에 지질의 함량은 감소하는 것으로 나타났다. 한편, 지질 클래스에서 단순지질의 경우 NL은 봄철에서 가을로 가면서 점차 증가하는 경향을 보였고, 반면 S, PL은 감소하는 경향을 보였다. PL에서는 대부분 PC만이 검출되었으며, 계절적으로는 봄에서 가을로 갈수록 감소하는 경향을 보였다. Squid is one of the most popular species over the East coast of Korea and sold as raw or processed one at the market. However, the liver and intestine occupied more than 20% of whole body are discarded wastefully at present. At this point of view, we analyzed lipid classes and fatty acid composition of liver, and tried to develop the utilities on the useful components of liver and intestine of squid. Alive squids were collected at the port of Jumunjin, Kangwon-Do, Korea, from April to Oct., 1988, and measured the body length, body weight and liver weight. Chemical composition of liver was analyzed by general method. Moreover, lipid class of total lipid was analysed using Iatroscan. As a results of this study, body weight, body length and liver weight increased after July, and hepatosomatic index(HSI) increased after May. Moreover, condition factor was maintained at moderate level after May. Among chemical components, water content had negative correlation with lipid and concentrations of protein and ash were not changed remarkly. In analysis of lipid class, it was proved that neutral lipid(NL) fraction of total lipid(TL) contained triacylglyceride(TG), sterol ester(SE) and free fatty acid(FFA) while polar lipid (PL) fraction of TL contained phosphatidylcholine(PC) dominantly.

Chemosensitivity is controlled by p63 modification with ubiquitin-like protein ISG15.

Jeon, Young Joo,Jo, Mi Gyeong,Yoo, Hee Min,Hong, Se-Hoon,Park, Jung-Mi,Ka, Seung Hyeun,Oh, Kyu Hee,Seol, Jae Hong,Jung, Yong Keun,Chung, Chin Ha American Society for Clinical Investigation 2012 The Journal of clinical investigation Vol.122 No.7

<P>Identification of the cellular mechanisms that mediate cancer cell chemosensitivity is important for developing new cancer treatment strategies. Several chemotherapeutic drugs increase levels of the posttranslational modifier ISG15, which suggests that ISGylation could suppress oncogenesis. However, how ISGylation of specific target proteins controls tumorigenesis is unknown. Here, we identified proteins that are ISGylated in response to chemotherapy. Treatment of a human mammary epithelial cell line with doxorubicin resulted in ISGylation of the p53 family protein p63. An alternative splice variant of p63, δNp63α, suppressed the transactivity of other p53 family members, and its expression was abnormally elevated in various human epithelial tumors, suggestive of an oncogenic role for this variant. We showed that ISGylation played an essential role in the downregulation of δNp63α. Anticancer drugs, including doxorubicin, induced δNp63α ISGylation and caspase-2 activation, leading to cleavage of ISGylated δNp63α in the nucleus and subsequent release of its inhibitory domain to the cytoplasm. ISGylation ablated the ability of δNp63α to promote anchorage-independent cell growth and tumor formation in vivo as well to suppress the transactivities of proapoptotic p53 family members. These findings establish ISG15 as a tumor suppressor via its conjugation to δNp63α and provide a molecular rationale for therapeutic use of doxorubicin against δNp63α-mediated cancers.</P>

Adoptive transfer of all-trans-retinal-induced regulatory T cells ameliorates experimental autoimmune arthritis in an interferon-gamma knockout model

Jeon, Eun-Joo,Yoon, Bo-Young,Lim, Jung-Yeon,Oh, Hye-Jwa,Park, Hyun-Sil,Park, Min-Jung,Lim, Mi-Ae,Park, Mi-Kyung,Kim, Kyung-Woon,Cho, Mi-La,Cho, Seok-Goo Informa Healthcare 2012 Autoimmunity Vol.45 No.6

<P>Maintaining an appropriate balance between subsets of CD4<SUP>+</SUP> helper T cells and T regulatory cells (Tregs) is a critical process in immune homeostasis and a protective mechanism against autoimmunity and inflammation. To identify the role of vitamin A-related compounds, we investigated the regulation of interleukin (IL)-17-producing helper T cells (Th17 cells) and Tregs treated with all-trans-retinal (retinal). CD4<SUP>+</SUP>T cells or total cells from the spleens of C57BL/6 mice were stimulated under Treg-polarizing (anti-CD3/CD28 and TGF-β) or Th17-polarizing (anti-CD3/CD28, TGF-β, and IL-6) conditions in the presence or absence of retinal. To analyze their suppressive abilities, retinal-induced Tregs or TGF-β-induced Tregs were co-cultured with responder T cells. Collagen-induced arthritis (CIA) was established in interferon (IFN)-γ knockout mice. On day 13, retinal-induced Tregs were adoptively transferred to mice with established CIA after second immunizations. Compared with TGF-β-induced Treg cells, retinal-induced Tregs showed increased Foxp3 expression and mediated stronger suppressive activity. Under Th17-polarizing conditions, retinal inhibited the production of IL-17 and increased the expression of Foxp3.Retinal-induced Tregs showed therapeutic effects in IFN-γ knockout CIA mice. Thus, we demonstrated that retinal reciprocally regulates Foxp3<SUP>+</SUP> Tregs and Th17 cells. These findings suggest that retinal, a vitamin A metabolite, can regulate the balance between pro- and anti-inflammatory immunity. A better understanding of the manipulation of Foxp3 and Tregs may enable the application of this tremendous therapeutic potential in various autoimmune diseases.</P>

Identification of Non-Muscle Nebulin Isoform in Human Brain Library

Joo, Young Mi,Lee, Min-A,Choi, Pyung-Rak,Choi, Jae-Kyoung,Lee, Yeong-Mi,Choi, Su-Il,Kim, Myong-Shin,Jeon, Eun-Hee,Kim, So-Young,Kim, Chong-Rak THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2004 Journal of biomedical laboratory sciences Vol.10 No.1

Nebulin is a (Mr 600~900 kDa) large actin-binding protein specific to skeletal muscle and thought to act as a molecular template that regulates the length of thin filaments. Cardiac muscles of higher vertebrates have been shown earlier to lack nebulin. Recently, full-length nebulin mRNA transcripts have been detected in heart muscle, but at lower levels than in skeletal muscle. Nebulin expression also was detected in the kidney, eye, and otic canal, suggesting that nebulin isoforms may also be expressed in these organs. We have searched for nebulin isoforms in brain of human using PCR and Northern blot. Here, we provide evidence that nebulin mRNA transcripts are expressed in brain. Seven nebulin isoforms (B, C, D, E, F, G and H form) are obtained in human skeletal muscle and four isoforms (B, C, G and H form) in human brain cDNA library. We cloned the 1.3 kb of nebulin fragment from human adult bran library by PCR. The identity of the PCR product was confirmed by sequence analysis. The partial brain nebulin sequence was 99% identical to the skeletal muscle cDNA as determined by Blast alignment. It contains two simple-repeats HR1, HR2 and linker-repeals exon 135~143 except exon 140. It was different from skeletal muscle B form, which contain HR1 and HR8. These data suggest that nebulin isoform diversity occurs even more extensively than previously known, likely contributing to the distinct thin filament architecture of different striated muscles.

Hypertensive Crisis During Excision of Retroperitoneal Mass in Patients with Abdominal Aortic Aneurysm-A Case Report-

( Mi Hyeon Lee ),( Joo Hyun Jun ),( Eun Mi Choi ),( Eun Mi Kim ),( Young Ryong Choi ),( Pil Hyun Jeon ),( Seung Hwa Baek ),( Mi Hwa Chung ),( Wha Ja Kang ) 경희대학교 경희의료원 2016 慶熙醫學 Vol.31 No.1

Paragangliomas are rare tumors that arise from extra-adrenal chromaffine tissues and that secrete catecholamine. The abnormal secretion of catecholamine can cause cardiovascular complications such as severe hypertension, cardiomyopathy, cardiac arrhythmia, and aortic aneurysm rupture. In particular, the risk of mortality and morbidity increases if the patient has not been diagnosed or if the preparation for a possible hypertensive crisis has been insufficient. Moreover, it can lead to high risks of cardiovascular complications if the patient has a concomitant disorder such as aortic aneurysm. We report a case of preoperatively undiagnosed paraganglioma that caused a hypertensive crisis during the surgical removal of a retroperitoneal mass and the repair of an infra-renal abdominal aortic aneurysm (AAA) and left common iliac artery aneurysm.
