The mutation of p53, a tumor suppressor gene, has been considered to play an important role in tumorigenesis in a variety of human cancers and the abnormal expression of p53 are frequently associated with poor prognosis. In order to examine the association of p53 overexpression with known prognostic factors including estrogen receptors (ER) and progesterone receptors (PR), we studied the status of p53 protein expression by immunohistochemical staining of paraffin sections of 29 endometrial carcinoma (25 endometrioid carcinoma, 2 clear cell carcinoma, and 2 serous carcinoma), obtained from hysterectomy. The results were as follows: The expression of p53, ER, and PR was present in 9/29 (31%), 3/29 (16%), and 12/29 (48%), respectively. The expression of p53 in endometrioid adenocarcinoma was present in 6/25 (24%) and showed significant correlation with histologic grade, nuclear grade, and myometrial invasion. The status of PR showed significant inverse correlation with histologic grade, nuclear grade and myometrial invasion. There was no significant correlation between ER status and these histologic factors. The expression of p53 was inversely associated with the status of PR, but statistically not significant. Our results indicate that p53 may be useful in predicting prognosis in endometrial carcinoma and will be able to provide helpful information in predetermination of aggressive behavior of the tumor in evaluation of curettage specimen.

Burns is children result in the loss of precious life, or if the child survives, in much suffering from physical, emotional, social, and economic problems. These burn accidents to children happen in the bustle of family life and frequently without any warning. With this background information, this study was designed to identity types of burns in children and mother's attitudes towards, and knowledge of burn prevention, in order, to not only, in still a safety consciousness regarding the seriousness of burn accidents and the strengthening prevention, but also as basic data towards the development of an educational program aimed at prevention. From May 1 to May 25 in 1997, data were collected from the mothers of children attending five day care centers and kindergartens located in Seoul, which had been selected for the study. The tools used for the study, which were developed by the researchers, surveyed the type of burns suffered by children, mother's knowledge of burns and attitudes toward burn accidents. The data were analyzed through real numbers percentages and analysis was done using SPSS computer programs. The results of the study show that the most frequent type of burn accidents were those caused by hot water(55.4%) and these were frequently related to everyday habits that easily lead to danger. Further, the first aid treatment following a burn was weak. The majority of the mothers had not instructed their children on who to contact in the cape of a fire, first aid for burns, or how to take escape in the case of a fire. This left the children in a defenseless position in case of a fire. The mothers showed a lack knowledge, on what to do when a blaze is discovered, how to put out a fire, first aid for burns, escaping from a fire and appropriate water temperature, in that 50% of the time they answered incorrectly. From this study a prevention program, HIPP(Home Injury Prevention Program) could be developed that includes fire prevention habits and first aid for burns. This program can be used with kindergarten and elementary school children for group education fire prevention and can be used as a foundation for construction of a system of facilities and equipment to prevent fires and also prevent injury from fires.

BACKGROUND: IL-4 is known as a potent stimulating factor and, TNF-α and IFN-γ suppress collagen synthesis of dermal fibroblasts. However, relatively little is known about interaction of these cytokines. OBJECTIVE: The purpose of this study was to evaluate the interactional effect of TNF-α and INF-r for the type I collagen gene expression and promoter activation produced by IL-4. METHODS: Using dermal fibroblasts from the normal skin cultured with three cytokines, IL-4, TNF-α and IFN-γ, we examined Northern blot analysis with each cDNA and assayed CAT activity with human pro a 2(l)collagen(COL1A2)/CAT reporter gene chimeric construct. RESULTS: Compared to the control, treating with IL-4 resulted in prominent elevation of both type I procollagen mRNA levels and prce 2(I) collagen promoter activity. IL-4 with TNF-α suppressed the IL-4 induced elevations, whereas IL-4 with IFN-γ did not reveal the obvious suppression of the elevations produced by IL-4. Fibroolasts treated with IL-4 together with IFN-γ and TNF-α completely abolished the type I procollagen gene expression and the activation of COL1A2 promoter gene elicited by IL-4. CONCLUSION: IL-4 induced enhancement of type I collagen gene expression was synergistically suppressed by TNF-α and IFN-γ on transcriptional level.
