PURPOSE: To understand the meaning of death seen by nursing students through art works. METHOD: The qualitative research method and the content analysis were used. The text were essays written by 42 senior nursing students about their impressions on death through art works. RESULT: Statements were classified into six categories and twenty six themes. The six categories include definitions of death, feelings about the death of a main character, responses to the death of the main character, feelings of significant others about the death of the main character, feelings of participants in this study, and oaths of the participants in this study. CONCLUSION: It is shown that participants recognize their position as nursing students, although they may not escape the fear of death, will learn to cope with death, and the dying in a suitably professional manner. In this respect, the study is considered to be helpful for the students in learning the knowledge and information which are needed for hospice nursing care more effectively.

PURPOSE: The purpose of this study was to analyze the subjectivity of contents related to death as a nursing curriculum subject for nurses and students. METHOD: The Q-methodology which provides a method for analyzing the subjectivity of each items was used. The 34 selected Q-statements sorted by each of the 36 participants were classified into a normal distribution by using a 9 point scale. The collected data were analyzed using the QUANL PC program. RESULTS: Four types of content related to death nursing curriculum were identified. Type I is the psychologically sympathetic type, Type II is the clinical based experience type, Type III is the physically comfort seeking type, and Type IV is the human-understanding oriented type. CONCLUSION: The results of this study show that different approaches to education are needed to address the four types of content related to death as a nursing curriculum subject. Both contents and characteristics need to be considered.

Phase-partitioning with Triton X-114 (TX114) was applied to the TSP antigen, which may be preferentially associated with the cell wall of M. tuberculosis. The hydrophilic protein components of the TSP antigen were successfully separated from integral hydrophobic macromolecules. To further characterize and examine the cellular immune response of the aqueous fraction of the TSP antigen (TSPa), the in vitro properties of the antigen were measured by lymphoproliferation; surface expression of IL-2 Ra on T lymphocytes was analyzed by flow cytometry; and the cytokine mRNA expression pattern was determined by RT-PCR. Significant lymphoproliferative responses to the TSPa antigen were observed in healthy tuberculin reactive donors after a 5 day in vitro stimulation. TSPa treatment of PBMCs from healthy tuberculin positive subjects for 5 days resulted in progressive augmentation of IFN-r, II 2, and IL-2Ra mRNA expression, as measured by RT-PCR, but considerably reduced IL-4 mRNA expression. In addition, the TSPa antigen stimulated more IL-12 p40 mRNA production than did the PPD antigen, and graduaBy suppressed IL- 10 mRNA expression. Moreover, the CD3' T cells of tuberculin positive subjects displayed a profound increase in their expression of the II 2Ru protein (39.0%) in response to the TSPa antigen. Proliferation was correlated with IL-2 and IL-2Ra mRNAs, but not correlated with distinct IFN-r or IL-12 p40 mRNA production. These findings strongly suggest that the TSPa antigen preferentially evokes the generation of a Thl-like immune response in healthy tuberculin reactors.

Tumor-draining lymph node mononuclear (TDLMN) cells are specifically sensitized to the growing tumor but such cells are deficient for mediating an antitumor response. In this study, we examined the feasibility of using mycobacterial 30 kDa or Triton X-100 solubilized protein (TSP) antigen to stimulate mononuclear cells of colon cancer-draining lymph node for the generation of cell mediated immune effector cells. The proliferative response of TDLMN cells stimulated with mycobacterial 30 kDa or TSP antigen was determined by H-thymidine incorporation assay. The proliferation of TDLMN cells to mycobacterial 30 kDa or TSP antigen was significantly increased in PPD (+) patients, but a poor response to the 30 kDa or TSP antigen was observed in PPD (-). The expression on ro T cells to mycobacterial 30 kDa or TSP antigen was assessed by flow cytometry. The ro T cells from PPD (+) patient responded only to 30 kDa antigen but to TSP antigen. An investigation of cytokine mRNA expression was undertaken using reverse transcription- polymerase chain reaction (RT-PCR) to follow TDLMN cells stimulated with the 30 kDa or TSP antigens for 5 days. The IFN-r and TNF-a mRNA expression was only induced in TDLMN cells of PPD (+) patient in response to the 30 kDa or TSP antigen. The IL-2 mRNA expression was induced in both PPD (+) and PPD (-) in response to the 30 kDa or TSP antigen. But the IL-4 mRNA expression was not induced in response to the 30 kDa or TSP antigen. These results suggest that the 30 kDa and TSP antigens may serve as biologic response modifier for the generation of cell mediated immune effector cells.

Hepatoma is one of the frequent cancers in Korea with an extremely poor prognosis. The prognostic factors in hepatoma are presence of venous invasion, multiplicity, size, and curative resection, but all things about prognosis are not elucidated yet. DNA ploidy pattern is one of the possible prognostic factors in HCC. Moreover, the study on DNA ploidy in Korean HCC is very scarce, so we studied DNA ploidy pattern in Korean HCC patients. We used formalin-fixed paraffin-embedded tissues from resected hepatoma specimens and the DNA ploidy was analysed with a flow cytometry system. Of the total 40 cases studied, 27 cases(67.5%) showed evaluable Coefficient of Variation(CV) level(less than 10). Among them 13 cases(48.1%) had an aneuploidy pattern. There were significant correlations between DNA ploidy and tumor size, presence of portal thrombi and TNM stage, although other conventional clinicopathologic prognostic factors did not show any significant correlation with DNA ploidy. In cases of tumors larger than 5 cm or presence of portal vein invasion, aneuploidy pattern was more frequently detected(p<0.05). But the prognostic significance of DNA ploidy pattern was not detected in resected hepatoma patients(p>0.1). Because of some limitation of paraffin-embedded tissue in flowcytometric analysis and heterogeneity of DNA ploidy pattern in HCC, we think that we should study multiple fresh samples in a prospective manner.

Background: The quality of a vaccine depends strongly on the effects of the adjuvants applied simultaneously with the antigen in the vaccine. The adjuvants enhance the protective effect of the vaccine against a viral challenge. Conversely, oil-type adjuvants leave oil residue inside the bodies of the injected animals that can produce a local reaction in the muscle. The longterm immunogenicity of mice after vaccination was examined. ISA206 or ISA15 oil adjuvants maintained the best immunity, protective capability, and safety among the oil adjuvants in the experimental group. Objectives: This study screened the adjuvant composites aimed at enhancing foot-andmouth disease (FMD) immunity. The C-type lectin or toll-like receptor (TLR) agonist showed the most improved protection rate. Methods: Experimental vaccines were fabricated by mixing various known oil adjuvants and composites that can act as immunogenic adjuvants (gel, saponin, and other components) and examined the enhancement effect on the vaccine. Results: The water in oil (W/O) and water in oil in water (W/O/W) adjuvants showed better immune effects than the oil in water (O/W) adjuvants, which have a small volume of oil component. The W/O type left the largest amount of oil residue, followed by W/O/W and O/W types. In the mouse model, intramuscular inoculation showed a better protection rate than subcutaneous inoculation. Moreover, the protective effect was particularly weak in the case of inoculation in fatty tissue. The initial immune reaction and persistence of long-term immunity were also confirmed in an immune reaction on pigs. Conclusions The new experimental vaccine with immunostimulants produces improved immune responses and safety in pigs than general oil-adjuvanted vaccines.

Present study was aimed to investigate the immunological activities of the 47 kDa glycoprotein antigen from Treponema pallidum and conducted on 24 patients with syphilis, (early, late, spontaneously healed, congenital and treated patients) and on 17 normal healthy controls. Two opposite lymphoproliferative manifestations to the 47 kDa antigen were observed in syphilis patients by H-thymidine incorporation assay. Ten responders (stimulation index [Sl] >4) showed a 3-fold-higher proliferation than the nonresponders, and four of those responders were spontaneously healed patients. Furthermore, analysis by flow cytometry indicated a preferential expansion of CD4' T lymphocytes by the 47 kDa antigen in the spontaneously healed syphilis patients. Stimulation of PBMCs of spontaneously healed syphilis patients with the 47 kDa antigen for greater than 72 hrs resulted in piogressive augmentation of IFN-r, IL-2Ra and IL-2 mRNA measured by RT-PCR, but considerably reduced IL-4 and IL-10 mRNA expression. However, patients with late latent syphilis exhibited more increased IL-4 and IL-10 mRNA expressions in response to the 47 kDa antigen than spontaneously healed syphilis group. In contrast to other groups, when cultured with the 47 kDa antigen very low IFN-#y, IL-2Ra and IL-2 mRNA expressions were shown in early syphilis group. These data suggest that the Th1-predominant cellular responses induced by the 47 kDa antigen may be involved in the clinical outcome of syphilis and provide the immunologic basis for further functional studies regarding the role of the 47 kDa in the immunopathogenesis of syphilis.

Treatment by All-trans retinoic acid (ATRA) followed by anthracycline-AraC chemotherapy has improved the outcome of acute promyelocytic leukemia. ATRA is usually well tolerated, but a few major side effects can be observed. Retinoic acid syndrome (RAS) often occurs during the induction chemotherapy of acute promyelocytic leukemia. A pericardial effusion is a common cardiac manifestation but myocarditis has been rarely documented. Here we reports a very rare case of fully recovered myocarditis as a result of RAS related to ATRA administration during induction treatment of acute promyelocytic leukemia which documented by echocardiographic evidence.

Foot-and-mouth disease (FMD) is an acute epidemic that spreads rapidly among cattle and pigs. In 2014, in Korea, despite enforced vaccination, the type O Southeast Asia (SEA) topotype viruses (Mya-98 lineage) infected mainly cattle and pigs simultaneously, thereby causing enormous damage. If a vaccine that is completely protective against this FMD virus is developed and used, it can become a very important preventive measure in Asia, which is where this type of virus mainly circulates. The SEA topotype has been steadily evolving and transforming into new variations since it became epidemic in Asia. Therefore, it became necessary to develop a new vaccine that could provide protection against the FMD virus strain that was responsible for the 2014–2015 outbreak in Korea. This study aimed to develop a vaccine that would provide complete protection against the SEA topotype FMD virus to control sporadic FMD outbreaks, which occur despite the enforcement of vaccination, and to completely prevent virus shedding, thereby preventing the virus from spreading. The vaccine candidate virus developed in this study showed low pathogenicity and can be distinguished from the wild-type FMD virus strain. The developed vaccine was able to protect mice from SEA and Middle East–South Asia topotype virus strains and induced high titers of antibodies against both virus strains in pigs, thereby confirming the sufficiency of its protective function. In particular, the results of the SEA topotype virus challenge test in pigs revealed that perfect immunity was created in the vaccinated pigs, without virus shedding and viremia.
