Programrned cell death (PCD), or apoptosis, is a process by which cells die in response to specific physiological and toxicological signals. This genetically programmed form of cellular suicide is intirnately involved in many biological processes including growth, metamorphosis, embryogenesis, and oncogenesis. Cells undergoing PCD in normal and neoplasmic tissues display the following biochemical and morphological features: internucleosomal DNA fragmentation, reduced cell volume, condensed chromatin in nucleus, zeiosis and generation of apoptotic bodies containing intact organelles and plasma rnembrane. Hybridoma cell production, resulting from the fusion of myeloma cells with antibody producing spleen cells, is widely used in various fields of life science. This technique requires hypoxanthine guanine phosphoribosyl transferase (HGPRT) deficient mutant myeloma cell line as a fusion partner. When these mutants cell is treated with aminopterin plus hypoxanthine-thymidine (HAT) after the cell fusion they are selectively and efficiently eliminated remaining fused hybridoma celis. But there hasn't been any report regarding the selective elimination mechanism of this HGPRT mutant myeloma cell. By using HGPRT myeloma P3-X 63-Ag8.653 (V653) as a model system, this study demonstrated that PCD was induced by aminopterin treatment of this V653 cell line. And the sequential ultrastructural changes during this death process were observed by using electron microscope. When V653 cells were incubated with 0.4 uM aminopterin, DNA fragmentation was detectable after 3 hours and peaked between 12 and 18 hours of aminopterin treatment and the cell viability decreased in a time dependant manner. V653 cells incubated with amiopterin showed following ultrastructural changes during the death process. Dilatation of rough endoplasmic reticulum (RER) and detachment of ribosomes were the earliest ultrastructural changes and first seen after 30 minute incubation. Dilatation of perinuclear cisternae began to appear after 1 hour and deformation of nucleoplasm such as decreased electron density of perinuclear heterochromatin and increased electron density of euchromatin were seen after 3 hours. Increased electron density of cytoplasm, decreased cell volume, condensation of chromatin and apoptotic bodies were observed in many cells after 9 hours but vacuolation by severe dilatation of RER was seen in some cells. 24 hours after incubation with aminopterin, many cells showed typical form of apoptosis characterized by cell shrinkage, increased electron density of cytoplasm and apoptotic bodies. On the contrary, some cells showed different type of cell death characterized by increased cell volume, decreased electron density of cytoplasm, severely dilated RER and apoptotic bodies. In both types of cells, mitochondrial cristae and limiting membrane of mitochondria are comparatively well preserved. In other cells, nuclei did not show significant changes but there were deformations of mitochondria such as markedly increased electron density and formation of lamella bodies. The death process of V653 cell was not synchronized among cells. The results of this study proved that aminopterin-induced selective elimination of fusion partner V653 myeloma cell is due to PCD. The earliest ultrastructural changes observed in this process were dilatation of RER and detachment of ribosomes. And there were two distinct morphological types in the PCD.

We report a case of 68-year-old male patient who was confirmed as d'emblee type of mycosis fungoides. The skin lesions showed sharply rnargined multiple reddish brown coIarcd papules, ndules, and tumors on the groin, thign, abdomen, and neck. The microscopic findings showed the epidermotropism and pautrier's micruabscess in the epidermis, and the infiltration of atypical cells in the dermis. The electron micrascopic findings showed irregular contour of the nuclear mernbrane within atypical lymphocytes. Thc lesions were gradually diminished by superficial radiation therapy.

PURPOSE: This study identified effects of dietary and physical activity interventions including dietary interventions or physical activity interventions alone or combined dietary-physical activity interventions to improve symptoms in metabolic syndrome including abdominal obesity, high triglycerides, low high density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose through meta-analysis. METHODS: Articles on metabolic syndrome X published from 1988 to 2013 were searched through electronic databases, Google Scholar, and reference reviews. Methodological quality was assessed by the checklist, SIGN (Scottish Intercollegiate Guidelines Network). RESULTS: In the meta-analysis, there were 9 articles reporting 13 interventions with 736 participants. Using random effect models, the dietary and/or physical activity interventions showed a lower mean difference in waist circumference ( - 1.30 cm, 95% CI: - 2.44~ - 0.15, p =.027). The combined dietary-physical activity interventions showed a lower mean difference in waist circumference ( - 2.77 cm, 95% CI: - 4.77~ - 0.76, p =.007) and systolic blood pressure ( - 5.44 mmHg, 95% CI: - 10.76~ - 0.12, p =.044). Additionally, interventions of over 24 weeks yielded a lower mean difference in waist circumference ( - 2.78 cm, 95% CI: - 4.69~ - 0.87, p =.004) and diastolic blood pressure ( - 1.93 mmHg, 95% CI: - 3.63~ - 0.22, p =.026). CONCLUSION: The findings indicate that dietary and/or physical activity interventions for metabolic syndrome reduce central obesity with no adverse effects. This finding provides objective evidences for dietary and physical activity management on metabolic syndrome as an efficient intervention.

PURPOSE: The purpose of this study was to develop a specialized education curriculum aimed at helping nurses prepare for running and managing a Maternal-Child Health Center (Postpartum Care Center). METHOD: This study was conducted by an academy and industry joint research group consisting of professors of Nursing, and nurses actually running a Postpartum Care Center. The group compiled job descriptions of nursing through document research, interviews and observation during site visits, surveys, and seminars. They then performed a feasibility study and developed the final curriculum. RESULT: The education curriculum is a 32-week (2semester) program compromised of a theory part (12 credits, 180 hours) covering maternal and infant care and business start-up and field practice (3 credits, 45 hours). Courses in the theory part include an antenatal care, overview and details of maternal care, starting a business and its management. Of these courses, the overview of a maternal care course was developed with web-based contents. Field practice is designed to give students opportunities to visit Postpartum Care Centers, observe the care provided, and get hands-on experience. CONCLUSION: The specialized education curriculum is a 32-week course comprised of 12 credits on theory of antenatal care, overview and details of maternal care, infant care, starting and operating a business and 3 credits of field practice.

PURPOSE: This study was conducted to explore the experience of unwed mothers, to describe the structure of the understanding of this experience for mothers and to explore nursing interventions for this situation. METHODS: The subjects were 4 unwed mothers. The data was collected by in-depth interviews and participant observations from February 2004 to June 2004. Each person was interviewed 4-5times, taking about one and a half hours for each session. Data was analyzed by the phenomenological method suggested by Giorgi. RESULT: The understanding of the experience of unwed mothers resulted in "lightness of sexual cognition", "knowledge deficit of pregnancy", "suffering form pregnancy", "ambivalence of the situation", "appearance of mothering", "worrying about society's view". CONCLUSION: Sex education programs, a one-round, formal lecture-type education is presently dominant, so that education and training programs can be systematized at school and home. The difficult point for unwed mothers to endure is that society doesn't accept them; therefore, we have to change our point of view, and try to work out the problems.
