The uptake of glucose for metabolism and growth is essential to most animal cells and is mediated by glucose-transporter (GLUT) proteins. The aim of this study was to determine which class of glucose transporter molecules was responsible for uptake of glucose in the mouse early embryo and at which stage the corresponding genes were expressed. In addition, co-culture system with vero cell was used to investigate the effect of the system on GLUT expression. Two-cell stage embryos were collected from the superovulated ICR female and divided into 3 groups. As a control, embryos were cultured in 0.4% BSA-T6 medium which includes glucose. For the experimental groups, embryos were cultured in either co-culture system with vero cells or glucose-free 76 medium supplemented with 0.4% BSA and pyruvate as an energy substrate. 2-cell to blastocyst stage embryos in those groups were respectively collected into microtubes (50 embryos/tube). Total RNA was extracted and RT-PCR was performed. The products were analysed after staining ethidium bromide by 2% agarose gel electrophoresis. Blastocysts were collected from each group at 120hr after hCG injection. They were fixed in 2.5% glutaraldehyde, stained with hoechst, and mounted for observation. In control, GLUT1 was expressed from 4-cell to blastocyst. GLUT2 and GLUT3 were expressed in morula and blastocyst. GLUT4 was expressed in all stages. When embryos were cultured in glucose-free medium, no significant difference was shown in the expression of GLUTI1, 2 and 3, compared to control. However GLUT4 was not expressed until morular stage. When embryos were co-cultured with vero cell, there was no significant difference in the expression of GLUT1, 2, 3 and 4 compared to control. To determine cell growth of embryos, the average cell number of blastocyst was counted. The cell number of co-culture (93.8+/-3.1, n=35) is significantly higher than that of control and glucose-free group (76.6 +/- 3.8, n=35 and 68.2+/-4.3, n=30). This study shows that the GLUT genes are expressed differently according to embryo stage. GLUTs were detectable throughout mouse preimplantation development in control and co-culture groups. However, GLUT4 was not detected from 2- to 8-cell stage but detected from morula stage in glucose-free medium, suggested that GLUT genes are expressed autocrinally in the embryo regardless of the presence of glucose as an energy substrate. In addition, co-culture system can increase the cell count of blastocyst but not improve the expression of GLUT. In conclusion, expression of GLUT is dependent on embryo stage in preimplantation embryo development.

Clinical observations were made on 338 low birth weight infants, who were delivered at Pusan Wallace Memorial Baptist Hospital, during the 3 year periods from 1989 to 1991. The results were as follows; The incidence of LBWI was 5.6% and sex ratio was 1:1.09. Among them AGA was 62.7%. 2) Of all infants, 47.3% were in the birth weight range of 2251-2500 gm and 25.1% were in the gestational age group of 37-38 week. 3) LBWI were most prevalent among mothers under 20 years old and over 41 years old. 4) The Incidence of LBWI was higher in multiparity than primiparity and in multiple pregnancy than single pregnancy. 5) Vaginal delivery was 63.9% and c-section delivery was 36.1%. 6) The order or frequency of the etiology of LBWI was multiple pregnancy, premature rupture of membrane and toxemia. 7) The mortality rate of LBWI was 12.7% and mortality rate by weight-gestational age was lower in AGA group than SGA and LGA group. 8) A Higher mortality rate was noted in the group of lower birth weight infant, and in the group of more shortened gestational age. 9) 48.8% of death occured within ist day of birth. The common causes of death were respiratory distress syndrome, asphyxia, and apnea.

PURPOSE: The purpose of this study was to identify attributes of the concept of cancer survivorship. METHODS: Walker & Avant's concept analysis framework (2005) was used to review the medical & nursing text books, medical and nursing research articles related to cancer survivorship and published from 1985 to 2011. RESULTS: There were nine aspects of the concept of cancer survivorship: A process, liminality, uncertainty, life-changing experience, complexity, unique experience, duality of positive and negative aspects, partnership, and need for support. Antecedents of cancer survivorship were cancer diagnosis and perception as a cancer survivor. Empirical referents of cancer survivorship were survival rate, quality of life, adaptation to the survivorship experience, and health-related hardiness, social support, spirituality, and health behavior. The consequences of cancer survivorship were effects on the physical, psychosocial, spiritual and socio-economic well-being of the patients. CONCLUSION: This concept analysis of cancer survivorship is expected to contribute to promotion of survivorship care in the clinical field by removing conceptual ambiguity and confirming the true meaning of survivorship care.

OBJECTIVE: The purpose of this study was to determine the important factors affecting survival and pregnancy rate in frozen-thawed embryo transfer cycles. METHODS: we performed reprospective analysis in 738 cycles of frozen-thawed embryo transfers, in relation to the insemination methods, the freezing stage of embryo, patient's age, infertility factors and the origin of injected sperm in ICSI cycles. After conventional IVF or ICSI, the supernumerary PN stage zygotes or multicellular embryos were cryopreserved by slow freezing protocol with 1,2-propandiol (PROH) as a cryoprotectant. RESULTS: The survival rates of thawed embryos were 69.3% (1585/2287) in conventional IVF group and 71.7&% (1645/2295) in ICSI group. After frozen-thawed embryo transfers, 27.0% (92/341) and 32.0% (109/341) of pregnancy rates were achieved in conventional IVF and ICSI group, respectively. There were no significant difference in the survival and pregnancy rates according to the insemination methods, the freezing stage and patient's age. However, the pregnancy rate (36.2%) of male factor infertility (22.9%). In ICSI group, the origin of injected sperm did not affect the outcome of frozen-thawed embryo transfer cycles. CONCLUSION: The present study demonstrates that acceptable clinical outcomes can be achieved after the transfer of frozen-thawed embryos regardless of the stage of embryos for freezing, the patient's age and the origin of injected sperm.

Vulvar melanosis (VM) is clinically characterized by asymmetric macules or patches of varying size with a tan to black color and irregular borders. VM is more commonly found among perimenopausal women with a median age of 42 years. The exact pathogenesis of VM is not well understood. The proposed etiological factors for VM include oral contraceptive use, infection with human papillomavirus, and chronic inflammatory skin diseases such as lichen sclerosus et atrophicus. Histologic examination can easily differentiate mucosal lentiginosis from melanoma, but VM superimposed on a background of anogenital lichen sclerosus, both clinically and histologically, may mimic malignant melanoma. There have been two cases of VM associated with Dowling-Degos disease in the Korean dermatologic literature. To the best of our knowledge, this is the first case of VM associated with lichen sclerosus et atrophicus in the Korean dermatologic literature.

Syringoid eccrine carcinoma (SEC) is a rare cutaneous malignant tumor thought to be derived from eccrine sweat glands. It is usually present in the scalp and face and often occurs in the fourth to seventh decades of life. A 76-year-old female patient visited our department with a 3-year history of a lesion showing a 5×4 cm-sized erythematous firm plaque with ulceration on her right shoulder. Histological findings revealed a tumor consisting of numerous proliferating tubular structures with two layers of basaloid cells with cellular atypia. Some ductal structures showed a tadpole appearance. Based on these findings, the final diagnosis was SEC. The patient was treated with slow Mohs micrographic surgery and a full-thickness skin graft and did not show any recurrence during the follow-up period of 6 months. Herein, we report a very rare case of a 76-year-old woman diagnosed with SEC that developed on the right shoulder.

PURPOSE: After discharge from the hospital, very low birth weight infants require care consultation, information, and interaction and so forth, due to sequelae, different growth and developmental pattern; which increase the burdens and the worries of patients in nurturing them. With the counseling of experts in the related fields, the authors and the Food for the Hungry have run a department of childcare for a year, emphasizing on more family support than extreme early detection of disabilities. This study reports on relieving child care anxiety, promoting growth and development, educating parents on home treatment of sequelae, finding and coping with minor disabilities. METHODS: The subjects were chosen among infants under 1,500 g of birth weight and younger than a corrected age of 6 months. Meetings were held once in a month for a year. Infant care support classes were taught by experts in their fields including a music therapist (with play program), neonatologist, a children's nurse, a child-care director, a clinical psychologist, a rehabilitation therapist, a social worker and, a nutritionist. Within the self-dependent groups, the families were able to share their concerns and experiences on child-caring. Second home visits were carried out to monitor home oxygen therapy, tube feeding, cerebral palsy signs, and to find neglect or abuse in suspected cases. RESULTS: Fifty-one infants participated; the average weight was 1,060 g, the average gestational age was 27 weeks and 2 days. Eighteen were boys and 23 girls. The average age of the mothers was 33.4, and there were 26 appropriate for gestational age, 8 small for gestational age, and, 5 large for gestational age. Twenty three were first-born, 13 were second-born, 1 was third-born, and twins were 4 pairs. Home visits were done in 33 families, and secondary visits were done in 6 families. The depression score of mothers in the attendant group decreased from 10.47+/-5.18 to 8.18+/-5.87 (P=0.080). CONCLUSION: The depression score of mothers in the attendant group decreased after infant care support classes.
