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.

Introduction : Chronic hemodialysis patients have been psychological problems because of being compelled to follow a dialysis schedule for a long period of time. Specificially, depression and anxiety are so frequently observed that psychological management is requireed for most hemodialysis patients. Fragnance has been known to have beneficial psychological and physiological effects on human. This study was designed to investigate the psychological effect of aromatherapy on chronic hemodialysis patients. Methods : 40 subjects of this study selected from Je Young-Sung Internal Medicine Clinic in Busan. The experimental group were random assigned to 20 subjects who had visited on Monday,& Wendesday & Friday and received aromatherapy every day for 2 weeks. the control group were random assigned to 20 subjects who had visited on Tuesday & Thursday & Saturday and did not receive any intervention. Experiment had been conducted from July. 7th July 21, 2003 and anxiety by Spilberger's state anxiety scale and depression by Zung's Scale were measured in the course of aromatherapy for both experimental group and control group. A control period consisting of natural hospital smells was established before each test session, and then aromatic test conditions were systematically evaluated for odorless conditions as well as aromatic conditions containing 100% lavender necklace for 2 weeks. Data were analyzed by, frequency, percentage, mean, S.D. χ²- test, t-test. Results : 1) Anxiety scores were not significantly decreased in the experimental group(54.57±13.20) after treatment compared to the control group(49.45±12.41)(t=1.225, p=.228). 2) Depression scores were significantly decreased in the experimental group(43.95±5.63) after treatment compared to the control group(49.65±9.84)(t=-2.367, p=.023). Conclusions : These findings indicate that the aromatherapy may decreased depression. It is suggested that the aromatherapy could be an effective nursing intervention to reduce to depression by chronic hemodialysis patients.

T lymphocytes are thought to play a central role in cell mediated immune response. To Study the T lymphocyte proliferative response to 30-kDa antigen purified from Mycobacterium tuberculosis H37Rv, peripheral blood lymphocytes isolated from healthy subjects were stimulated with the 30kDa antigen, crude antigen or PHA. Healthy subjects were divided into three groups so that PPD(+), PPD(±) and PPD(-). The proliferations of lymphocytes were measured by the incroporation of ^3H-thyrnidine. The results were summarized as follows: 1. For the PPD(+) person, at concentration of < 1 ㎍/ml, the proliferative response to 30-kDa antigen resulted in a mild reduction but crude antigen showed relatively rapid reduction. For the PPD(-) person, decreasing the concentration of the both antigens showed rapid reduction of proliferation 2. The lymphocytes proliferations to 30-kDa antigen and crude antigen were significantly increased in PPD(+) group when compared to those in PPD(-) group, but PHA response was no significant difference. 3. The sensitivity and specificity of lymphocyte proliferation assay to 30-kDa antigen and crude antigen when compared with skin test results were 92.3%, 100% and 76.9%, 50%, respectively.

The Purpose of this study is to present an actual example for procedures for developing a PBL package based on philosophical backgrounds derived from Problem-based learning. To perform a systemic study on the operations of an intergrated curricula under multi-disciplines, a research team made up of several professors with different academic backgrounds was formed. Among the four situations for the patients with perception-adjustment disorder, especially a procedure for the development of PBL package which can be used in the emergency room situation has been proposed. The little(2000)'s PBL package model has been applied for this study. Tha package includes course objectives, learning objectives, concept map, situation scenario. tutor guide, and evaluation method. It is believed that learning objectives achievement procedures designed as a part of a problem-based learning package development procedures for the nursing of patients with perception-adjustment can be achieved at the same level as the learning objectives for the science of nursing founded by the Korean Nurses Association.

The cell mediated immune response appears to result from the specific recognition of an antigen. by T lymphocytes. It has been well recognized that T cell play an important roles in the induction of tuberculin hypersensitivity and immunity to tuberculosis. In order to evaluate effect on T lymphocyte proliferative response to purified 30-kDa antigen from Mycobacterium tuberculosis, stimulation effects of peripheral blood lymphocytes with 30-kDa antigen, crude antigen and PHA were measured by MTT colorimetric assay. Three groups of healthy subjects, representing PPD(+), PPD() and PPD(-) persons, were investigated. The proliferative response to 30-kDa antigen were elicited the plateau at concentration of 20 to 0.1㎍/ml, crude antigen showed rapid reduction as decreasing the concentration of antigen, for the PPD(+) person. Both antigens, at concentration of <1㎍/ml, failed to stimulate lymphocytes of the PPD(-) person. Therefore the concentration of 30-kDa antigen to induce optimal stimulation was 1㎍/ml. The lymphocyte proliferation to 30-kDa antigen and crude antigen were significantly increased in PPD(+) group when compared to those in PPD(-) group, but PHA response was no significant difference. These results suggest that 30-kDa antigen could stimulate lymphocyte from PPD(+) population and MTT colorimetric assay could be applied to assess proliferative response of lymphocyte.

Identification and characterization of individual components of M.tuberculosis have long been a focus of research on tuberculosis. The 30-kDa and 32-kDa antigens are major constituents of M bovis BCG and M. tuberculosis culture fluids. Because 30-kDa and 32-kDa antigens are partially identical, these antigens are difficult to purify in large amounts by biochemical techniques. This study was performed to purify the 30-kDa and 32-kDa antigens complexes primarily purified by 50% ammonium sulfate precipitation, hydroxylapatite chromatography and Sephadex G-75 gel filtration. And then further purification for separation of the two antigens was accomplished on preparative isoelectric focusing. Recovery of 30-kDa and 32-kDa antigens during above the purification procedures were 28% and 14%, respectively, and 147.0 and 59.8-fold purification were showed, respectively. On silver stained SDS-PAGE gels, the purified 32-kDa antigen gave a single band at 32-kDa molecule, while 30-kDa antigen gave one major band at 30-kDa molecule and faint additional band at 32-kDa. The pI of 30kDa-and 32-kDa antigens were 4.3 and 4.6, respectively. The partial identity between these two antigens was observed through the same pattern of reactivity of antigens in the ELISA and precipitation pattern of immunodiffusion. We also examined the immunological activities of both purified antigens by splenocyte proliferation of BCG-infected mice. Proliferative response to the 30-kDa and 32-kDa antigens did not show significant difference. However, macrophage-like cells existed in spleen cells from BCG-infected mice were involved in the suppression of the proliferative response to mycobacterial antigen. These results suggest that the 30-kDa and 32-kDa antigens could be effectively purified by the IEF and reactions of partial identity between the two antigens were found. However, 30-kDa antigen was the more immunogenic antigen than 32-kilodalton.

T lymphocytes are thought to play a central role in cell mediated immune response. To study the T lymphocyte proliferative response to purified 30-kDa antigen from Mycobacterium tuberculosis H37Rv, peripheral blood lymphocytes(PBL) isolated from healthy controls and tuberculosis patients were stimulated with the 30-kDa antigen, crude antigen and PHA. Healthy controls and tuberculosis patients were divided into PPD(+), PPD(-) groups and AFB(-), AFB(+) groups, respectively. PBL proliferation were determined by the ^3H-thymidine incorporation assay and MTT colorimetric assay. PBL proliferation with 30-kDa and crude protein antigens measured by both methods were almost identical(r=0.74, p<0.001). The lymphocyte proliferation to 30-kDa antigen and crude antigen were singnificantly increased in PPD(+) healthy controls and tuberculosis patients when compared to those in PPD(-) controls, but response to PHA was no significant difference. Analysis to T cell subsets of proliferated lymphocytes performed by the indirect immunoalkaline phosphatase techniques were no difference between not only healthy controls and patients groups, but also stimulated antigen or PHA, and especially, at all groups, the percentage of T8 cell was higher than that of T4 cell.
