The present study is aimed to investigate the clinical and pathologic features of GI lymphomas and the immunocytochemical characteristics, using 71 cases of primary GI lymphomas examined at the Department of Pathology, Yonsei University College of Medicine, Youngdong Serverance Hospital and Yonsei University Wonju College of Medicine from January, 1976 to December, 1985. Results obtained were as follows: 1) Sixty eight cases were Non-Hodgkin's lymphoma and 3 Hodgkin's lymphoma. Surgical resection was done in 58 patients and surgical biopsy in 13. 2) The primary sites of the tumors were stomach, small intestine, ileocecal area and large intestine in a descending order of frequency. 3) The mean age at the time of diagnosis was 45 years. The tumor of the small intestine was generally detected in the younger age and that of the large intestine in the older age. The overall male to female ratio was 1.9 : 1. 4) Abdominal pain was the most common presenting symptom irrespective of the sites of the tumor. Duration of the symptoms were evenly distributed from hours to 12 monthes. 5) The size of the tumors was less than 10 cm in the largest dimension in most of the cases (79.3%). The gross types of the GI lymphomas were ulcerative (27.6%), polypoid (20.7%), multinodulated (17.2%) and diffuse thickening. The rate of lymph node involvement was 44.4% in tumors confined to the serosa, while 82.6% in tumors with serosal penetrations. 6) Classification of 68 cases of Non-Hodgkin's lymphoma according to Working Formulation revealed 50 cases of intermediate grade, 13 cases of high grade and 5 cases of low grade. According to Rappaport classification, all were diffuse types, among which diffuse histiocytic type was the most common. According to Lukes-Collins classification, 60 cases were B cell types, 4 cases genuine histiocytes types and 3 cases T cell types. Most of the gastric and intestinal lymphomas belonged to the follicular center cell (small and large cleaved, large cleaved) types. 7) Immunoperoxidase stains were done in 55 cases of malignant lymphomas. Thirty (65.9%) of 47 B cell lymphomas revealed a positivity for B cell markers. Twenty three (48.9%) of them showed a monoclonality, in which kappa/IgG pattern was most frequently demonstrated. Four cases of true histiocytic lymphomas were positive for alpha-1-antichymotrypsin and lysozyme, the former of which was seemed to be a more sensitive marker for histiocytic differentiation. An attempt was made to evaluate the significance of the degree of reactive histiocytic infiltrates within the lymphoma in relation to the progosis, but correlation could not be made because of the limited cases.

The clinical syndrome of venoocclusive disease of the liver is one of several manifestations of regimen-related toxicity that can occur after high-dose cytoreductive therapy. Hepatic dysfunction after bone marrow transplantation may result from a number of causes such as pretransplant chemoradiation, graft-versus host disease, drugs for prophylaxis of graft-versus host disease, venoocclusive disease, various infections, and infiltration of recurrent malignancy. The clinical distinction of these causes may be difficult and the treatment of each cause is also quite different. Therefore the diagnosis of veno-occlusive disease is important. Veno-occlusive disease affects zone 3 of the liver acinus and produces a syndrome of jaundice, painful hepatomegaly, and fluid retention. Veno-occlusive disease occurs in up to 50% of the patients who undergo BMT and is usually associated with a high mortality rate. In Korea, there are a few case reports on venoocclusive disease after BMT which were only confirmed by clinical symptoms. This is a first report of two cases of hepatic veno-occlusive disease after allogenic BMT, which were proven by laparoscopic liver biopsy in our country.

Despite advances in surgery, radiotherapy, and chemotherapy, the survival of patients with oral squamous cell carcinoma has not significantly improved over the past several decades. Gene therapy is currently under investigation and shows us new possibility of cancer curing method. This experiment was undergone to find out the cell growth inhibition effect and evidence of apoptosis by HCCS-1(human cervical cancer suppressor-1), one of the candidates of tumor suppressor gene, transducted to human oral cancer cell line. To determine the efficiency of the adenovirus as a gene delivery vector cell line was transducted with LacZ gene and analysed with X-gal staining. Northern blot was performed to confirm the transfection with HSCC-1 gene and cell viability was assessed by cell cytotoxicity assay using cell count kit(CCK). To show the evidence of apoptosis, DNA fragmentation assay and flow cytometry(FACS) were performed. We had successfully construct the recombinant HSCC-1 adenovirus(Ad5CMV-HCCS-1), and importation efficiency was 20% at 2 MOI(multiplicity of infection), 80% at 20 MOI. Northern blot analysis showed that a single 0.6kb mRNA transcript was expressed in Ad5CMV-HCCS-1 transducted cell lines. As a result of CCK, when comparing to control subjects, transducted group showed 50% growth inhibition. In DNA fragmentation assay, according to increasing of MOI, DNA volume was diminished. In FACS analysis, DNA distribution showed fragmentation.This results imply that HCCS-1gene has growth inhibition effect in human oral cancer cell lines through apoptosis induction.

BACKGROUND: Mental stress prebably leads to disease by the effect on autonomic nervous system, especially on cardiovascular nervous system it leads deleterious effects ranging from the apperarence or worsenig of ischemia to lethal arrhythmia or sudden death. Especially after myocardial infarction this risks were increased. PURPOSE & METHODS: In order to assess the effect of postural change and arithmetic test on the state of autonomic nervous system in patients with AMI(acute myocardial infarction) autoregressive power spectral analyses were applied to 21 healthy subjects(51.9+/-6.5 years) and 20 AMI patients(55.3+/-7.4 years) during supine, standing and arithmetic test. RESULTS: R-R interval and systolic blood pressure decreased during standing compared with during supine position but there were no remarkable changes during arithmetic test compared with during supine position. In two groups, both during standing and during arithmetic test, compared with during supine position, the remarkable increase of LF(low frequency) spectral parameters(Nu, p<0.001) and decrease of HF(high frequency) spectral parameter(Nu, p<0.001) were observed. And during arithmetic test, compared with during standing, the remarkable increase of LF spectral parameter(Nu, p<0.01) and decrease of HF spectral parameter(Nu, p<0.01) were observed. LF/HF ratio and LFCCV/HFCCV ratio, so an index of sympatho-vagal balance, significantly increased during standing and during arithmetic test compared with during supine position and the increase was more prominent during arithmetic test(p<0.05). There was no significant difference of spectral parameters beteen two groups. CONCLUSION: In conclusion, sympathetic activity increased during standing and during arithmetic test. Especially, during arithmetic test it induced only sympathetic activity to increase remarkably without significant hemodynamic changes. The state of autonomic nervous system 7-10 days after AMI was not different from that of healthy subjects. Among the spectral parameters, Nu was more useful than either PSD or CCV in assessing autonomic nervous activity.

BACKGROUND: After the introduction of the meningococcal ACWY-CRM197 conjugate vaccine (MenACWY-CRM) in 2012 and the meningococcal ACWY-diphtheria toxoid conjugate vaccine (MenACWY-DT) in 2014, immunization was recommended for certain high-risk groups including new military recruits in Korea. However, comparative immunogenicity studies for these vaccines have not been performed in Korea. Here, we compared the immunogenicity of these two vaccines in healthy adults. METHODS: A total of 64 adults, 20–49 years of age, were randomly divided into two groups (1:1) to receive either of the two vaccines. The sera were obtained before and 1 month after vaccination and tested for serogroup-specific serum bactericidal activity using baby rabbit complement. RESULTS: There were no significant differences post-vaccination in the geometric mean indices and the seropositive rate to all serogroups between the vaccines. The proportion of seropositive subjects after vaccination ranged from 88% to 100%. CONCLUSION: Both meningococcal conjugate vaccines showed good immunogenicity in healthy Korean adults without statistically significant differences. Further investigations for serotype distribution of circulating meningococci and the immune interference between other diphtheria toxin-containing vaccines concomitantly used for military recruits are needed to optimize immunization policies.

Background: Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease with increased prevalence in the elderly. Telomeres are repetitive DNA sequences found at the end of the chromosome, which progressively shorten as cells divide. Telomere length is known to be a molecular marker of aging. This study aimed to assess the relationship between telomere length and the risk of COPD, lung function, respiratory symptoms, and emphysema index in Chronic Obstructive Pulmonary Disease in Dusty Areas (CODA) cohort. Methods: We extracted DNA from the peripheral blood samples of 446 participants, including 285 COPD patients and 161 control participants. We measured absolute telomere length using quantitative real-time polymerase chain reaction. All participants underwent spirometry and quantitative computed tomography scan. Questionnaires assessing respiratory symptoms and the COPD Assessment Test was filled by all the participants. Results: The mean age of participants at the baseline visit was 72.5±7.1 years. Males accounted for 72% (321 participants) of the all participants. The mean telomere length was lower in the COPD group compared to the non-COPD group (COPD, 16.81±13.90 kb; non-COPD, 21.97±14.43 kb). In COPD patients, 112 (75.7%) were distributed as tertile 1 (shortest), 91 (61.1%) as tertile 2 and 82 (55%) as tertile 3 (longest). We did not find significant associations between telomere length and lung function, exacerbation, airway wall thickness, and emphysema index after adjusting for sex, age, and smoking status. Conclusion In this study, the relationship between various COPD phenotypes and telomere length was analyzed, but no significant statistical associations were shown.
