BACKGROUND: In recent years, lymphocyte subset analysis in peripheral blood is widely performed using erythrocytes-lysed whole blood and two color immunofluorescence/flow cytometry method. Use of fresh blood drawn within 6 hours of staining is recommended, and some patients have to revisit the hospital for blood collection. We tested whether 24 hours-refrigerated/stored whose blood can be used for lymphocyte subset analysis. METHODS: Twenty consecutive blood samples from patients (including nine HIV positive patients) collected in EDTA-vacutainer were tested: 1) on the day of sampling using fresh blood kept at room temperature for up to 6 hours until staining (as recommended by the manufacturer) and 2) on the following day using the same tube of blood refrigerated for 24 hours after the first staining. Two colon immunofluorescenc staining was done using Simultest(TM) IMK-Lymphocyte kit (Beckon Dickinson, U.S.A.) and flow cytometric analysis was performed using FACScan and SimulSET(TM) software (Becton Dickinson, U.S.A.). Results of alive kinds of Lymphocyte subsets (CD3+, CDl9+, CD3+CD4+CD3+CD8+, CD3-CDl6+ and/or CD56+) on day 1 and day 2 were compared by pained-t test and Wilcoxon signed rank test. RESULTS: There was no significant change of values for all of the lymphocyte subsets except CD3+CD8+suppressor/cytotoxic (S/C) T cells. There was a slight but statistically significant change in S/C T cells (39.9%-->41.8%: 1.9%, p=0.008) after 24 hours of refrigeration, and this change was observed mainly in HIV-positive patient group. However, there was no significant change in the absolute count of helper/inducer T cells or CD4/CD8 ratio, and the change of S/C T cells in these patients was not considered to be of clinical significance. CONCLUSIONS: The difference in the values of lymphocyte subsets between fresh blood and 24 hours-refrigerated blood was negligible and it is concluded that 24 hours-stored blood samples can be used for lymphocyte subset analysis for clinical purposes.

BACKGROUND: The HLA system is known to be the most polymorphic genetic system in human and there are characteristic racial differences in the distribution of HLA antigens, alleles, and haplotypes. This study was performed to examine the frequency of HLA antigens, alleles and haplotypes in Koreans. METHODS: Two thousand healthy Koreans registered for unrelated bone marrow donors were subject to the study. HLA-A, B and C antigens were typed by the serological method, and HLA-DR DNA typing (low resolution) was done by PCR and reverse hybridization. HLA allele and haplotype frequencies and linkage disequilibrium values were calculated by the maximun likelihood method using the computer program of the 11th International Histocompatibility Workshop. RESULTS: HLA antigens identified in 2000 Koreans were 14 in A locus, 33 in B locus, 8 in C locus and 12 in DR locus. Alleles showing frequencies of more than 10% in decreasing order of frequency In each HLA locus were A2, A24, A33, All, B44, B62; CBL, Cw3, Cwl, Cw7, DR4, DR2, DRl3, DR8, and DR9. Among A-B, C-B, B-DR 2-locus haplotypes, A33-B44, A30-B13, Al-B37, Cwl-B54, Cw4-B62, B7-DR1, B37-DR10 showed strong positive linkage disequilibrium (Chi-square > 1000). The most common A-B-DR haplotypes in Koreans occurring at frequency of more than 2% were A33-B44-DRl3 (4.8%), A33-B58-DRl3 (3.2%), A33-B44-DR7 (2.6%), All-B62-DR4 (2.3%), A24-B7-DR1 (2.3%), and A30-Bl3-DR7 (2.1%) Comparison of the distribution of A-B-DR haplotypes among east Asian populations reveals that Koreans are most close to Japanese, but show higher degree of polymorphism in the distribution of HLA haplotypes compared to Japanese. CONCLUSIONS: The results obtained in this study can be used as basic data for Koreans in the fields of organ transplantation, disease association studies and anthropologic studies.

5.Validity and Reliability of Informatics Competencies for Nurses Among Korean Nurses.
Journal of Korean Academy of Adult Nursing 2008;20(3):470-480
PURPOSE: The purpose of this study was to validate the scale of Informatics Competencies for Nurses developed by Staggers, Gassert & Curran(2001) among Korean nurses. METHODS: The subjects of this study were 58 RN-BSN students and 314 nurses in Busan, Ulsan and Kyoungnam province. Data were collected by questionnaires from June to August, 2006 and from October, 2006 to August, 2007 and were analyzed by Principal Component Analysis for construct validity and Cronbach's alpha coefficient for reliability. RESULTS: A factor analysis was conducted and 30 items that had a factor loading more than .40 were extracted. The explained variance from 5 factors was 55.33% of the total variance. The factors were named 'basic computer usage', 'medical informatics-related software usage', 'computer related information management', 'perception of informatics', and 'information search using internet'. The first factor consisted 10 items which explained 29.89% of the total variance and the second factor contained 7 items. The Cronbach's alpha coefficient was .91 among the 30 items. CONCLUSION: This scale, Informatics Competencies for Nurses, was proved as a proper instrument to apply to Korean nurses.

6.Duplicated Vertebral Artery : Literature Review and Clinical Significance
Journal of Korean Neurosurgical Society 2018;61(1):28-34
OBJECTIVE: Duplication of the vertebral artery (VA) is a rare vascular variant. This paper describes the anatomy and embryological development of duplicated VAs and reviews the clinical significance.METHODS: Computed tomography (CT) angiography was performed in 3386 patients (1880 females, 1506 males) between March 2014 and November 2015. We defined duplication of the VA as a condition in which the VA has two origins that fused at different levels of the neck.RESULTS: Ten of the 3386 patients (0.295%) who received CT angiography had a dual origin of the VA; three on the left side, and seven on the right side. In all seven with right dual origin of the VA, both limbs of the VA origin originated from the right subclavian artery. In all three patients with left dual origin of the VA, both limbs of the VA originated from the left subclavian artery and aortic arch. In all 10 patients, the medial limb of the duplicated VA was located posteriorly and medially to the common carotid artery (CCA) and anteriorly and laterally to the vertebral transverse foramen. In two patients, the medial limb of the duplicated VA was located in close proximity to the CCA. In another two patients, the medial limb of the duplicated VA was located in close proximity to the CCA, carotid bifurcation, and proximal internal carotid artery.CONCLUSION: Although duplication of the VA is asymptomatic in most patients, clinicians should consider this anomaly during diagnosis and treatment.

PURPOSE: There is increasing attention to smart-learning as a new education paradigm. The purpose of this study was to identify the level of intention to use smart-based Continuing Nurse Education (CNE) and factors influencing intention to use smart-based CNE. METHODS: Participants were 486 nurses from 14 organizations, including 12 hospitals, a nurses association, and an office of education. Data were collected from November 5 to 18, 2014 using self-report questionnaires. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation, and stepwise multiple regression. RESULTS: The mean score for intention to use smart-based CNE was 6.34 out of 10. The factors influencing intention to use smart-based CNE were nursing informatics competency, current unit career, and smartphone addiction. These variables explained 10% of variance in intention to use smart-based CNE. CONCLUSION: The findings of this study suggest that efforts to enhance the nursing informatics competency of nurses could increase usage rate of smart-based CNE. The CNE policy makers will find this study very useful and the findings of this study will help to provide insight into the best way to develop smart-based CNE.

From May, 1985 to July, 1986, 500 cases of intraocular lenses were implanted, and all 500 cases had been followed up for more than 2 months. The results were as follows: 1. In the 500 cases of intraocular lens implantation, the number of patients were 318 men and 115 women. Patient's age was largely distributed to fifth decade in men and fourth decade in women. 2. IOL power ranged from +13.5D to +23.0D in PCL and ranged from +12.5D to +20.0D in ACL. The most frequently used IOL poeer was +19.5D in PCL and +18.0D in ACL. 3. Postoperative corrective vision with IOL was improved up to 0.8 or better in 446 cases(89.2%). 4. During operation, some complications were developed and those were posterior capsular rupture in 19 cases(3.8%), hyphema in 15 cases(3.0%), Descemet's membrane stripping in 2 cases(0.4%), and corneal edema in 1 case(0.2%). More frequently developed postoperative complications were clinical cystoid macular edema in 26 cases(5.2%), secondary glaucoma in 18 cases(3.6%), and distorted pupil in 13 cases(2.6%). 5. Postoperative corrective vision lower than 0.4 was observed in 22 cases(4.4 %), and the causes were diabetic retinopathy, cystoid macular edema, vitreous opacity, congenital cataract, phacoanaphylactic uveitis, endophthalmitis, amblyopia, optic nerve atrophy, corneal opacity, glaucoma, hypertensive retinopathy, and others.

Moyamoya disease is a rare occlusive cerebrovascular disease characterized by stenosis or occlusion of the main cerebral arteries. It has a tendency for multifactorial inheritance and familial occurrence, although its pathogenesis is not clear. We observed this disease in two girls from the same family:one was eight years old and the other was 45 months. They presented with transient ischemic attacks. We performed cerebral angiography on both patients and magnetic resonance angiography (MRA) on the younger. Both approaches showed the typical features of moyamoya disease, and MRA successfully revealed abnormal findings specific for the disease in the second child. Both children received encephaloduroarteriosynangiosis (EDAS) and this produced good results. MRA is thus a powerful and noninvasive way of detecting individuals at high risk of developing this disease. Considering the reported familial incidence of moyamoya disease in Japan, a careful search for family members using MRA would probably reveal many more such cases in Korea.
