A 11-year-old, female Russian Blue cat was presented with anorexia, vomiting, and diarrhea lasting for 3 days. Abdominal ultrasonography revealed a hypoechoic, non-circumferential, and eccentrically formed intestinal loop with altered wall layering and thickening of the tunica muscularis. After surgical resection, histopathologic examination confirmed an infiltrative, round-cell neoplasm composed of sheets and cords of neoplastic mast cells within a fibrotic, edematous stroma. The cat was alive and healthy 6 months after surgery. To the best of our knowledge, this is the first reported case of an intestinal mast cell tumor in a Russian Blue cat in South Korea.

4.A Study of Pilot-Efficacy.
Korean Journal of Aerospace and Environmental Medicine 2009;19(1):8-13
Pilot's complacency and confidence have been implicated as a contributing factors in numerous aviation accidents and incidents. It is related to ones belief that one is capable of performing in a certain manner to attain certain goals which is called 'Self-Efficacy' as a psychological concept. The purpose of this study was to construct and validate pilot's self-efficacy scale. This study examined the necessity of pilot efficacy in terms of pilot's confidence and complacency, and considered what is components and processes of pilot self-efficacy through the reference to literature. This Study newly defined 'pilot-efficacy' as vocational self-efficacy in flight operation field. Based on literature review and advisory group's review, there made 3 factors of Pilot-Efficacy:Flight-Efficacy, Relational/Communication Efficacy, and physical and psychological Stress-Coping Efficacy. Preliminary pilot-efficacy scale was administered to pilot group analysis Item analysis was conducted to select appropriate items and common factor analysis was done to identify the subcomponents of pilot efficacy scale. In result, 35 items were selected. The measurement of pilot efficacy for individual makes it possible to predict pilots' behavior when they make decision both normal and non-normal situation. This scale is expected to be not only predictable but also useful to enhance aviation safety. Finally, suggestion for following studies were discussed.

PURPOSE: The purpose of this study was to examine the experiences of the use of external breast prostheses among breast cancer survivors in Korea. METHODS: A qualitative descriptive study was conducted, using focus groups. Data were collected from breast cancer survivors who were patients of C women's hospital in Seoul, Korea. Data were analyzed using content analysis in order to identify significant themes. RESULTS: Participants included forty breast cancer survivors who had mastectomy as a surgical treatment. Four themes emerged from the collected data were: 1) concern over the high price of external breast prosthesis, 2) irregular use of external breast prosthesis, 3) unsatisfied with mastectomy bra, and 4) wanting to hide or not to talk about using breast prosthesis openly. CONCLUSION: Since most participants reported irregular use and negative experiences related to external breast prosthesis or mastectomy bra use, healthcare workers should allow more time for proper fitting and counseling and consulting with breast cancer survivors. In addition, health care providers as well as family and friends should keep in mind that cancer survivors need support that can help them cope by using positive reframing. Furthermore, improvements in the coverage of costs and services are needed for these women. This would be helpful for breast prosthesis users.

PURPOSE: The purposes of this study were to explain the phenomena of hot flashes in climacteric women by using Mexameter, Skin Thermometer, Corneometer, and Laser Doppler Perfusion Imager (LDPI) objectively and to identify the interrelation between the subjective and objective measurements of hot flashes by comparing the two as reported in retrospective questionnaires. METHODS: The participants were one hundred women (45-60 yr) who were not currently on hormone therapy, and had reached hot flash scores of 10 or higher. Hot flashes were measured in a temperature and humidity controlled room for 7 hr from 10 am to 5 pm. Hot flashes were measured subjectively and recorded via the Hot Flash Diary Report. When participants felt the hot flashes, they were measured objectively by Mexameter, Skin Thermometer, Corneometer, and LDPI. RESULTS: The frequency of hot flashes in participants ranged from 1 to 7 times. When hot flashes occurred in participants, the erythema, skin temperature, skin hydration, and blood perfusion showed statistically significant changes in all measurements. But, the subjective and objective measurements of hot flashes showed only weak correlations. CONCLUSION: Results indicate a need for future research with subjective and objective measuring instruments chosen depending variations identified for the study.

MAGE (melanoma antigen gene) is a tumor specific shared antigen, presented by HLA class I molecules, which is recognized by cytotoxic T lymphocytes. MAGE proteins are expressed in malignant tumor cells, in contrast to no expression in normal or benign tissues except for testis and placenta. MAGE might be a potential target for immunotherapy of malignant tumors. However, its biological aspects associated with cell cycle are not yet described. The flow cytometry is a useful tool for objective and quantitative analyses of heterogenous tumor cell population. To understand the status of MAGE related to cell cycle and its relationship with p53 as the G1 checkpoint regulator, p21, and PCNA as a proliferative index, we investigated expression of MAGE-3 protein, mutant p53, p21, and PCNA by flow cytometry and immunohistochemical stain. In addition, double stains for MAGE-3/p53, p53/PCNA, and p53/p21 were analysed with bivariate flow cytometry. DNA histograms using MAGE-3/PI (DNA) and p53/PI (DNA) were also analysed. The cell line (PNUH- 12) used for this study originated from a hypopharyngeal squamous cell carcinoma, which has point mutation (exon 7, C-->G) of p53. The expression rate of MAGE-3 was 83%, PCNA 85%, and p53 81%. No expression for p21 was identified. MAGE-3 was expressed in cytoplasm, while both PCNA and p53 were expressed in nuclei of tumor cells. With bivariate analyses, coexpression rates of MAGE-3/p53 and p53/PCNA were 0.96 and 0.97, respectively. Both MAGE-3 and p53 showed constantly high level throughout the cell cycle. These results suggest that expression of MAGE-3 and mutant p53 is not dependent on the cell cycle. p21 seems to be inactivated.

PURPOSE: MAGE (melanoma antigen gene) is a tumor associated antigen, presented by HLA class I molecules, which is recognized by cytotoxic T lymphocytes. The expression of MAGE proteins are confined to malignant tumor tissues, except for the normal testis and placental tissues. Therefore, MAGE may be a potential target for immunotherapy of malignant tumors. However, biological aspects associated with the cell cycle are not yet described. MATERIALS AND METHODS: The material used for this study was a novel human squamous cell carcinoma cell line (PNUH-12) from the hypopharynx, which had one point mutation of 78th base, C to G, in exon 7 of p53 gene. To understand the role of MAGE in relation to cell cycle and its relationship with p53 as the Gl checkpoint regulator, the expressions of MAGE-3 protein and mvtant p53 (Mtp53) were accessed by flow cytometry and immunohistochemistry. Double stains for MAGE-3/Mtp53 was analyzed with bivariate flow cytometry. DNA histograms using MAGE-3/PI (DNA) and Mtp53/PI (DNA) were also analyzed. RESULTS: The expression rate of MAGE-3 and Mtp53 were 83% and 85%, respectively. MAGE-3 was expressed in cytoplasm, while M:p53 were expressed in the nuclei of the tumor cells on the immunohistochemical sections. With bivariate analyses, coexpression rate of MAGE-3/Mtp53 was 0.96, and MAGE-3 and Mtp53 constantly showed high levels throughout the cell cycle except Go. CONCLUSIONS: These results mean that (I) MAGE-3 might have yet unknown relationship with mutant p53, (2) expressions of MAGE-3 and Mtp53 are not dependent on the cell cycle in PNUH-12 hypopharyngeal squamous carcinoma cell line, and suggest that MAGE-3 might have a role as important as p53 during the development of malignant tumors.
