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.

This study was performed to investigate the effect of kimchi intake on free radical and oxidative substance production in young adults and the elderly. Daily kimchi intake by people in their twenties (n = 93, 20 to 29 years old) and over sixty-five (n = 143, over 65 years old) in M city were surveyed and blood was drawn to analyze the free radicals in their plasma. The average amount of kimchi intake by the subjects was 115.8 +/- 91.7 g. The amount of kimchi intake of those in their twenties (106.1 +/- 80.6 g) was significantly lower than that of those over sixty-five (125.5 +/- 102.9 g, p<0.05). Concentrations of total free radicals and OH radicals were 27 and 33% greater respectively, in those over sixty-five than in those in their twenties, indicating that more free radicals were produced by the older group. The concentration of GSH was not signiacantly different in the two groups, but that of GSSG in the over sixty-five age group was 53% greater than in the twenties group, which resulted in a 35% reduction in GSH/GSSG in the elderly group. TBARS concentration in the over sixty-five group was 26% greater than that of the twenties group. In order to see the effect of kimchi intake on free radical production, subjects in same age group were divided into two sub groups-the mean over and the mean under groups-according to the average amount of kimchi intake, which was 115.8 g. The total free radicals, the OH radicals, the GSH, the GSSG, and the GSH/GSSG in the twenties group were not significantly different in the two kimchi intake groups. However, those in the over sixty-five group were significantly different. The concentration of total free radicals and OH radicals of the mean over group were 21 and 26% lower respectively, than those of the mean ova. group (p<0.05). The GSH and GSH/GSSG of the mean ova. groups were higher by 8 and 12%, respectively. The correlation coefficient between the kimchi intake and the total free radicals was -0.1862 (p<0.05) and that for GSH/GSSG was 0.1861 (p<0.05). In conclusion, the production of free radicals and oxidative substances increased with age, and kimchi seemed to retard this phenomena.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)induces apoptosis in some cancer cells such as breast,prostate,lung,and colon cancer cells,but not normal cells.However,because the effects of TRAIL in gastric cancer cells is unclear,we undertook this study to clarify the effects of TRAIL and its mechanism. To assess the cytotoxicity of TRAIL,two human gastric cancer cell lines,SNU-484 and SNU601,were treated with TRAIL (0-200 ng/mL)in the presence or absence of cycloheximide (1 microgram/mL)for 24 h.Both SNU-484 and SNU-601 were sensitive to TRAIL-induced cell death in a dose-dependent manner.The combination of TRAIL (100 ng/mL)and cycloheximide (1 microgram/mL)for 24 h enhanced cell death and PARP cleavage by promoting activations of caspase-8, caspase-9,and caspase-3,relative to that of TRAIL alone.We further examined the expressions of death receptor 4 (DR4),death receptor 5 (DR5),and FLICE inhibitory protein (FLIP).Although DR4 and DR5 were expressed in both cell lines,the expression of long form (FLIPL )and short form (FLIPS )of FLIP were detected at the low levels. Overexpression of FLIPL or FLIPS in both cell lines rendered the cells resistant to TRAIL.Taken together,our results suggest that FLIP promotes human gastric cancer cell survival against TRAIL-induced apoptosis and is important modulator for TRAIL-induced cell death in human gastric cancer cells.

Purpose: This study was attempted to develop an entity theory about the sudden bereavement experience with the family by understanding and describing the semantic system of the adaptation experience of the family who experienced sudden bereavement. Methods: Data were collected through in-depth interview with a purposive sampling of nine people who experienced sudden bereavement. Data analysis was in the stages of open coding, axis coding, and selection coding by applying the grounded theory method. Results: As a result of this study, the core categories was 'Accepting loss and enduring life', the central phenomenon was 'Heartbreaking grief', the context was 'Guilty and regret', the action/interaction strategy were 'Immerse in the sorrow', 'Accepting reality', and the intervention condition was 'Supporting system'. As a result, the sudden bereavement experience presented 'A life to start again' and 'A difficult daily life to endure'. Conclusion Based on the results of this study, it can be seen that systematic and professional counseling strategies, multidisciplinary intervention programs and programs are urgently needed to care for the bereaved family members.

PURPOSE: The purpose of this study was to identify the relationships among distress from drinking, alcohol abstinence self-efficacy and outcome expectancy in youths. METHOD: The participants in this study were 174 university students who were enrolled by convenience sampling. The data were collected from March to August, 2005. Descriptive statistics and Pearson's correlation coefficients with SPSS 12.0 were used to analyze the data. RESULTS: There were significant differences in the physical distress from drinking according to gender, age, residence, drinking frequency and drinking capacity. There were significant differences in alcohol abstinence self-efficacy by drinking frequency and drinking capacity. There were significant differences in drinking outcome expectancy according to gender, drinking frequency and drinking capacity. The physical distress from drinking showed a significant positive correlation with alcohol abstinence self-efficacy (r=.312, p=.000) and negative correlation with drinking outcome expectancy (r=-.353, p=.000). Alcohol abstinence self-efficacy showed a significant negative correlation with drinking outcome expectancy (r=-.387, p=.000). CONCLUSION: There were relationships among physical distress from drinking, alcohol abstinence self-efficacy, and drinking outcome expectancy. These findings provide the basis to prevent problems of drinking by developing alcohol control program for university students.

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.

BACKGROUND: Fas is a member of the tumor necrosis factor (TNF)/nerve growth factor (NGF) receptor family. Triggering of the Fas receptor pathway by its ligand results in apoptosis. Soluble Fas consists of the extracellular region of Fas receptor and it binds to Fas ligand to inhibit the Fas and Fas ligand induced apoptosis. Recently some evidence indicates that the Fas/Fas ligand system represents an important pathway responsible for the induction of apoptosis in bone marrow CD34+ cells of patients with aplastic anemia. METHODS: We measured serum soluble Fas levels in 27 patients with aplastic anemia at diagnosis using ELISA to define the status of soluble Fas in this disorder. RESULTS: Levels of serum soluble Fas in patients with aplastic anemia were lower com-pared with that of normal healthy controls. No difference was noted in the serum soluble Fas levels according to severity of disease. No correlation was found between serum soluble Fas levels and hematologic parameters at diagnosis such as neutrophil count, lymphocyte count, platelet count and corrected reticulocyte count. CONCLUSION: These results indicate that serum soluble Fas levels are decreased in patients with aplastic anemia. Further studies recruiting more patients and measuring Fas receptor on peripheral blood lymphocyte subsets and bone marrow CD34+ cells concomitantly may be helpful to determine pathophysiology of bone marrow failure.

PURPOSE: To seek adequate sequence of MR angiography (MRA) on developmental venous anomaly in the brain. MATERIAL AND METHODS: We collected ten cases who demonstrated developmental venous anomaly on MR image. Eight patients among them, both 3D time-of-flight (TOF) with or without Gadolinium-DTPA enhancement and phase contrast(PC) were performed: TOF without enhancement in five, TO F with enhancement in six, and PC with 10 cm/sec in five, PC with 30 cm/sec in three, and PC with 5 cm/sec velocity encoding (VNEC) in two cases. RESULTS: On enhanced 3D TOF, both dilated collecting veins and medullary veins were well depicted in five of six cases, however, the signal intensity of the collecting and medullary veins are less than arteries. Dilated hyperintense collecting veins were well demonstrated on 3D PC with below the 10cm/sec VNEC in all seven cases, but the medullary veins were poorly defined. Unenhanced 3D TOF IVIRA could not reveal any dilated collecting and medullary veins in all five cases. CONCLUSION: Enhanced 3D TO F could demonstrate the collecting and medullary veins of developmental venous anomaly, however, 3D PC with below the 10 cm/sec VN EC could showthe dilated collecting and larger draining veins. We considered that combined enhanced 3D TOF MRA and PC with VENC 10cm/sec can substitute for conventional anglogram in the diagnosis of developmental venous anomaly.
