PURPOSE: Advanced gastric cancer, the most common malignancy in Korea is a kind of systemic disease. At dignosis, 50~80% of patients have systemic cancer. Therefore, the most patients require systemic chemotherapy. Cisplatin and 5-FU have been suggested to be active in the treatment of gastric cancer, a high response rate was observered with a combination of 5-FU infusion and cisplatin, and the biochemical modulation of 5-FU by leucovorin has been demonstrated to enhance the activity of 5-FU in gastrointestinal tract cancer. MATERIALS AND METHODS: The patients with advanced gastric cancer whose disease had relapsed or unresectable were treated with 5-FU(800 mg/m2 12 hr IV infusion, D 1~5), leucovorin(20 mg/m2 IV, D 1~5, max. 30 mg), cisplatin(100 mg/m2 15min IV dripping, D1). The cycles of treatment were repeated at 3-weeks intervals. RESULTS: Between Sep. 1994 and Aug. 1996, previously untreated 44 patients(39 eligible patients) were admitted to this study, the median age was 55 years(range 17~73) and male to female ratio was 20:19. The rate of complete remission was 5%(2/39), the rate of partial remission was 21%(8/39). The median-response duration was 26 weeks(5+~38+ ). The median-time to progression was 25 weeks(4+~62+). The range of overall survival time was from 4 to 62+ weeks. 24 weeks survival rate was 71.5% but the median survival time was not reached. The leukopenia and anemia were the main hematologic toxicities. Non-hematologic side effects were nausea, vomiting, diarrhea, stomatitis, peripheral neuropathy. These toxicities were observed commnonly, but tolerable. Two treatment-related deaths were associated with sepsis. CONCLUSION: Based on these results, FLP combination chemotherapy seems to be a moderate efficacy for advanced gastric cancer with tolerable toxicities. To confirm the efficacy further, the long-term follow up and a large scale of clinical studies are needed.

This study was carried out to investigate the intake patterns of health food according to the kind of disease of the elderly aged over 60 years living in the Chuncheon area. This study was conducted by using a questionnaire from December 1999 to the March 2000. The data was analyzed using a SPSS program. The results were summarized as follows : The poorer the self-perceived health condition, the lower the level of activity of daily living(ADL) and instrumental activities of daily living(IADL) were the higher. the frequency score of health food intake. The incidence of disease, such as arthritis(44.7%), hypertension(18.8%), digestive diseases(17.1%), diabetes(10.5%) were found to be higher. than other chronic diseases among the elderly. The frequency score of health food intake was not significantly different according to self-perceived health status, disease status, or the level of ADL and IADl.. The must important source of information for health food intake was the recommendation of friends and relatives(68.7%). Twenty eight point two percent of the elderly considered health foods to be effective, however 8.3% of the elderly considered them to be ineffective. The elderly with chronic diseases had taken health floods in the descending order of neuralgia-arthritis, hypertension, digestive disease, diabetes. The elderly with digestive diseases, diabetes, renal disease, neuralgia-arthritis and respiratory disease were inclined to habitually take health floods once or twice per year. Intake of Korean traditional folk food was as high as intake of registered health food and Chinese tonic medicine. The most frequently taken health food was tonic medicine, which is fo11owed by pumpkin, ginseng products, herbal tea formula with black goat, deer antler and Kye-so-ju. Intakes of health food such as tonic medicine, blood of the deer, royal jelly, aloe were found to be higher among the elderly with chronic diseases such as diabetes, hypertension, and digestive disease. However, intakes of ginseng products, deer antler, pumpkin, herbal tea formula with black goat and Kye-so-ju were found to be higher among the healthy elderly. The elderly with neuralgia-arthritis had taken sixteen kinds of health foods. From these results, a wide consumer education program should be developed to convince people of the importance of well-balanced diet and to choose proper health foods according to the elderly's health conditions. Also, comprehensive and scientific research into Korean traditional folk foods are needed for the correct use.

The formation and malignant progression of gliomas are generally considered to undergo multistepped process like other tumors. Loss of 13q is implicated in the later stage of progression of gliomas. The retinoblastoma susceptibility gene(RB gene), located at the 13q14, is a prototypic tumor suppressor gene. Many kinds of tumors are noted to have mutations of the RB gene. To determine whether the loss of 13q is associated with RB gene or not, and to find the intragenic mutation of RB, we examined 28 gliomas for loss of heterozygosity(LOH) at the RB locus using a polymerase chain reaction-based restriction fragment length polymorphism(PCR-based RFLP) assay. We found LOH in 13 of 28(46%) gliomas. Eight of 12(67%) high-grade astrocytomas, 3 of 6(50%) differentiated astrocytomas showed LOH. And we also detected LOH in 1 of 2 anaplastic oligodendrogliomas and in 1 of 7(14%) differentiated oligodendrogliomas. When we classify them into low-grade and high-grade gliomas, 4 of 14(29%) low-grade gliomas, and 9 of 14(64%) high-grade gliomas showed LOH, PCR-SSCP analysis was performed on exon, 8, 14, 15, 16, 19, 20, 21, 22, 24 to find mutations in remaining allele, and one case of mobility shift was identified in glioblastoma multiforme which showed LOH in PCR-based RFLP study. Our results demonstrate that RB deletions are detected in both low-grade high-grade gliomas, and unlike the p53 gene, genetic alterations of the RB gene in gliomas are mainly deletions rather than point mutations.

Mercury poisoning affects various organs including peripheral and central nervous systems, especially cerebellum. We report a case of mercury intoxication presenting cerebellar ataxia. From several days after exposure to mercury vapor, scanning speech, head titubation, bilateral limb and truncal ataxia developed and progressed slowly. On admission, brain MRI did not show remarkable change. However, nine months later, atrophic changes in both cerebellar hemispheres on follow-up brain MRI and perfusion defects in same areas on brain SPECT were found.

PURPOSE: To evaluate the radiologic features of endodermal sinus tumor of the ovary. MATERIALS AND METHODS:The radiologic findings of eight patients with pathologically-proven endodermal sinus tumor of the ovary wereretrospectively evaluated for bilaterality, size, margin, architecture, septa, local invasion, distant metastasis,ascites and lymphadenopathy ; serum alpha-FP was also evaluated. RESULTS: All endodermal sinus tumors were unilateralwith irregular septa and ascites ; the longest diameter was 7-18(mean, 12.6)cm. Four of eight tumors had smoothmargins and four, lobulated. Four were predominantly cystic in internal architecture, one was purely cystic, andthree were predominantly solid. There was local invasion or distant metastasis in three patients, andretroperitoneal lymphadenopathy in one ; in seven cases, alpha-FP level was more than 1.000ng/ml. CONCLUSION: Endodermal sinus tumors of the ovary appeared as nonspecific large complex abdominal masses and it was difficultto differentiate them from other malignant ovarian tumors. This tumor should be included in the differentialdiagnosis of a large complex abdominal mass in girls and young women, especially in patients with a predominantlycystic mass and markedly elevated serum alpha-FP.

Prolymphocytic leukemia (PLL) is a member of chronic lymphoproliferative disorders with relatively distinct clinical, morphologic, immunologic and prognostic features. The diagnosis of PLL is determined by more than 55% of prolymphocytes in the peripheral blood. It is characterized by leukocytosis, massive splenomegaly with little or no lymphadenopathy, and male prevalence. In immunophenotyping, the majority (80%) of the cases express B cell markers and the rest (20%), T cell type. We experienced a case of B-PLL. The patient was a 65 year-old man who presented with marked leukocytosis (110.5x109/L) and 78% of characteristic prolymphocytes in the peripheral blood. The bone marrow aspirate showed 13.6% of prolymphocytes and coarse granular positivity of prolymphocytes in PAS stain. The immunophenotyping of the leukemic prolymphocytes revealed the positivity of surface immunoglobulin (IgM, lambda type), HLA- DR and CD19. The monoclonal gammopathy (IgM, lambda type) was also detectable in the patient's serum.

Helicobacter pylori plays an important role in the pathogenesis of chronic gastritis, peptic ulcer disease, gastric cancer, and gastric mucosa-associated lymphoid tissue lymphoma. In Korea, the guidelines for the diagnosis and treatment of H. pylori infection in adults were revised in 2013. The European Helicobacter and Microbiota Study Group and Consensus panel released the fifth edition of the Maastricht Consensus Report for the management of H. pylori infection in 2015, and the European Society of Paediatric Gastroenterology, Hepatology and Nutrition and the North American Society of Paediatric Gastroenterology, Hepatology and Nutrition released the updated joint guidelines for children and adolescents in 2016. Considering these recommendations and recent progress in our research and that of other research teams, this study aimed to discuss the diagnostic strategies for H. pylori infection in children and adolescents.

Ginsan, a botanic polysaccharide extracted from Panax ginseng, has recently been reported to modulate mucosal immune response. In this study, we investigated the protective effect of Ginsan against fatal Vibrio vulnificus mucosal infection. A lethal dose of V. vulnificus (1.0 x 106 CFU/mouse) was nasally inoculated to mice. The bacterial count in the nasal associated lymphoid tissue (NALT) of the mouse was significantly reduced in the Ginsan-treated group. The Ginsan-treated group showed improved survival compared to the control group (100% vs 18%). To elucidate the effect of Ginsan on modulating host immune response, cytokine mRNA expressions involved in mediating inflammation were determined by semiquantitative RT-PCR in the NALTs of the infected mice. Most of the cytokine mRNAs were similarly expressed as the control group. However, COX-1 mRNA expression level was higher in Ginsan-treated group compared to the control group. The protective effect of Ginsan was antagonized by treating with a specific COX-1 inhibitor, SC-560. Thus, these data suggest that the protective effect of Ginsan against V. vulnificus infection is partly mediated by modulating COX-1 expression.
