Purpose : The purpose of this study was to evaluate the effect of nutritional support with enteral liquid supplement in cancer patients receving chemotherapy for possible benefit in nutritional, immunologic and golbal function of patients. Patients and Methods : From October 1995 to February 1997, 30 advanced cancer patients receving chemotherapy were divided two roups. The Nycare group, in addition to normal diet, Nucare^R enteral supplement was given for 1week right after chemotherapy for the duration of 2 chemotherapy cycles. Control group received only normal diet without parenteral fluid supplement for 2 chemotherapy cycles. Results : Median ages were 53 end 56 years for Nucare group and Contrl group respectively. Performance scores was less than 2 by ECOG scale. All patients were stage Ⅲ or Ⅳ. The physical parameters, such as weight, arm muscle circumference(AMC) and triceps skin fold(TSF) were decreased in both groups after 2 cycles of anticancer therapy. but it was less severe in Nucare group(p<0.05). Serum transferrin was maintained in mild deficit state in Nucare group, whereas it aggravated form mild to moderate deficit in Control group(p<0.05). Serum albumin level increased in Nucare group without statistical significance. but it decreased from normal to mild deficit in Control group. Serum total protein did not change significantly in Nucare group. but in Control group, serum total protein was decreased from 7.24±0.9 to 6.52±0.5(P<0.05). Total lymphocyte count did not change significantly in both groups. Conclusion : This study shows that the nutritional support with Nucare^R was effective in the prevention of nutritional deficit status in patients receving a nticancer chemotherapy.

Prediction of thrapeutic response to radioiodine in Graves' disease is poorly understood. Although thyrotropin binding inhibitor immunoglobulin(TBII) level is a strong index for relapse after antithyroid drug medication, conflicting results are reported regarding its prognostic significance in Graves' disease treated with RAI. This study is dengned to evaluate possible relationship between post-treatment hypothyroidism and TBII in Graves' disease treated with RAI. Fourty two patient with Graves' disease after radioiodine treatment were studied retrospectively. The subject were divided into hypothyroid group and euthyroid or hyperthyroid group. We evaluated the association of hypothyroidism and TBII with radioiodine treatment dose. The mean age of hypothyroid group was 48±11 years and euthyroid or hyperthyroid group was 47±12 years. There was no difference in two groups. And there was no significant difference in post- treatment TBII between two groups(49.9±28.5%, 29.9±14.3%, p-value >0.05). The treatment-dose had no influence on post-treatment thyroid state. Euthyroid or hyperthyroid group was done with 13.6±6.9mCi and hypothyroid group was 17.0±10.4mCi(p-value > 0.05). TBII had no prognostic significance on long-term hypothyrodism in Graves' disease treated with radioiodine. And, treatment-dose had no influence on post-treatment thyroid state.

Background: It is suggested that clinical practice in the areas of bone marrow transplantation and gene therapy might rely on the ex vivo expansion of hematopoietic stem/progenitor cells. However, the condition for ex vivo expansion of hematopoietic progenitor cells is not well established. The authors pursued a series of experiments to define the proper conditions for the expansion of hematopoietic cells in the short-term liquid suspension culture of mobilized peripheral blood CD34+ cells. Methods: 1.0ml cultures were initiated with 9×10^3 PB CD34+ cells, which were isolated from PB mononuclear cells (MNCs) by high-gradient cell sorting, in 12 well plates with the various combinations of hematopoietic growth factors(HGF). The following recombinant human HGFs were used: stem cell factor(SCF) 100ng/ml, granulocyte colony-stimulating factor(G-CSF) 100ng/ml, GM-CSF(granulocyte, macrophage colony-stimulating factor) 100ng/ml, interleukin-1 beta(IL-1B) 1ng/ml, interleukin-3(IL-3) 20ng/ml, interleukin-6 (IL-6) 100ng/ml. At the end of culture, colony-forming cells were evaluated by semisolid clonogenic assay. Results: 1) Using the high-gradient magnetic sorting system, CD34^+ cells were isolated with a yield of 40 3% 2) In 7 day culture of PB CD34^+ cells(9×10^3 cells), nucleated cells expanded mean 10×10^3(range, 9 to 20×10^3) with the addition of SCF alone, 35×10^3(range, 10 to 60×10^3) with SCF plus G-CSF plus GM-CSF, and 130×10^3(range, 40 to 300×10^3) with the combination of SCF, G-CSF, IL-1, IL-3, IL-6, GM-CSF. In 14 day culture, nucleated cells expanded 10×10^3 to 1,860×10^3 with combination of human hematopoietic growth factors. 3) In 10 day culture without medium change of PB CD34^+ cells, CFU-GM numbers expanded 16. 5 fold(range, 7 to 59 fold) with the addition of SCF plus G-CSF plus Il-1 plus IL-3, 31.3 fold(range, 20.5 to 101.1 fold) with the combination of SCF, G-CSF, IL-1, IL-3, GM-CSF. In 14 day culture with or without medium change of PB CD34^+ cells was inferior to 10 day culture for CFU-GM expansion. 4) There was no significant difference for CFU-GM expansion between five growth factors(SCF,G-CSF,IL-1,IL-3,GM-CSF) and six growth factors(five growth factors plus IL-6). Conclusion: The authors could confirm that short-term suspension culture of peripheral blood CD34+ cells could expand hematopoietic progenitor cells. Ten-day culture with medium change of CD34+ cells with the addition of five growth factors, i.e. SCF, G-CSF, IL-1B, IL-3, and GM-CSF, might be the most efficient in this system.

The purpose of this study was to suggest the developmental ideas for graduate school in Yougin University. For the methods of this study, the researches in administration of graduate students, personal researches in socialization of graduate school, and evaluation materials for graduate school were utilized. Additionally, the questionnaire survey about graduate students leas administered and analyzed and the ideas constructed from staff meeting for the development of graduate school were applied in preparing developmental plan. The results of this study are summarized as follow: 1. 1-2 years preparation - offers annual credits upto 30 - jop marketing upto 70% - advisor and student ratio 1 : 7 - professors' doctoral degree possession upto 90% - graduate school professors' research achievement upto 2 articles annually - research space per student upto 10m/2 3-4 years preparation - offers annual credits unto 33 - advisor and student ratio 1:4 - professors' doctoral degree possession upto 95% - graduate school professors' research achievement upto 2.5 articles annually 2. The educational goals of graduate school should be recognized among graduate students and the professionality of faculty members should be emphasized to teach graduate students in their relative major areas. The evaluation procedures for graduate class lecture and class administration in graduate school. 3. To reach unto lecture system, field study should be expanded and inter-credit system between Yongin universities and foreign university should be contracted. 4. Expanding of graduate school facilities should be cranked in to provine the optimal environment for the student education and schoolship should be widely offered to the students. 5. To promote the administrational development, the staff system should be changed from reverse hierarchy system to hierarchy system. Therfore, the number in lower administrational staffs should be larger than upper positions. And, the classification of authorities into department could be suggested for the efficacy of administration and management of graduate shool. 6. The specialization in each major should be emphasized. In the calc of graduate stool of physical education, the administration live should be unified in one body system. In the case of graduate school of business, one department of administration could be classified into management of sightseeing and tourism, management of distribution, tax accounting, then the specialty of the department can be forced. In the case of graduate school of art, the specialty can be forced by teaching highly performed skills and needed to switch from special graduate school to professional graduate school. The graduate school of health and school of environmental science are recommended to be built after all. Therefore, the connection between undergraduate and graduate curiculum can be established and open 2-3 more majors in the graduate school.

Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

Background : Cord blood(CB), which has no HLA restriction, is an alternative to bone marrow for hematopoietic stem cell transplantation. The use of cord blood, however, is limited by the number of progenitor/stem cells necessary to reconstitute the older child or adult. Therefore, ex vivo expansion of CB could have tremendous impact on diverse clinical settings. We studied the ex vivo expansion of isolated population of CD34_(+) cells from cryopreserved CB cells. Methods : CD34 cells were isolated from cryopreserved CB mononuclear cells. Purified cells were cultured with various combinations of hematopoietic growth factors including erythropoietin(EPO), stem cell factor(SCF), granulocyte-colony-stimulating factor(G-CSF), gra-nulocyte, macrophage-colony-stimulating factor(GM-CSF), interleukin-1β(IL-1β), 1L-3, and IL-6. After 7, 10 or 14 days of culture, the fold increases of colony-forming unit- granu-locyte, macrophage(CFU-GM), burst-forming unit-erythroid(BFU-E), colony-forming unit-mix (CFU-Mix), and high proliferative potential colony-forming cell(HPP-CFC) were evaluated. Results : Ten-day culture with the combination of EPO, SCF, G-CSF, IL-1β, and IL-3 resulted in a median of 60-fold increase of CFU-GM, which was greater than those with the combinations of less than 5 growth factors. The addition of IL-6 or GM-CSF to this combination did not enhance CFU-GM expansion. Ten-day culture was significantly superior to 7-day culture for CFU-GM expansion. Prolongation of culture to 14 days, however, revealed decreased expansion of CFU-GM compared to 10 days. BFU-E and CFU-Mix were expanded to 2~5 folds in 7-day culture with the combination of EPO, SCF, and G-CSF. Further expansion was not achieved in 10-day culture and colonies disappeared in 14-day culture. HPP-CFC was expanded to a median of 7.5 folds in 7-day culture with the combination of EPO, SCF, G-CSF, IL-1β, IL-3, and IL-6. Neither 10-day or 14 day-culture enhanced expansion of HPP-CFU. Conclusion : Cryopreserved cord blood cells maintain ex vivo expansion potential. In our system, 10-day culture with the combination consisting of EPO, SCF, G-CSF, IL-1β, and IL-3 seems to be adequate for hematopoietic progenitor/stem cell expansion from cryopreserved cord blood cells.
