OBJECTIVE: There is a large and increasing body of experimental and clinical data supporting the existence of variable estrogen receptors in both normal and neoplastic estrogen target tissue. Recently, exon 5 deleted estrogen receptor(D5-ER) has been identified in many estrogen dependent tumors. The purpose of this study is to assess the relationship between uterine myoma and D5-ER. METHODS: The relative amount of wild type estrogen receptor mRNA and D5-ER mRNA were examined in human myometrium and myoma tissue obtained from 12 myoma patients and 12 control subjects by RT-PCR. The correlation between WT/D5-ER ratio and age was also evaluated. RESULTS: There was no difference in expression of D5-ER mRNA not only between myoma and myometrim of the myoma patients, but also between myometrium of myoma patients and normal subjects. No significant correlation was found between D5-ER expression and age of the subjects in myometrial tissue. However, we could find negative correlation between WT/D5-ER ratio and age in myoma tissue. CONCLUSION: Upon these data, we conclude that D5-ER is a common variant mutation of estrogen receptor, which is not related with development of myoma. However, in myoma tissue, there is possibility that D5-ER may act some role in the growth of tumor.

We examined the p53 protein overexpression and evaluated its correlation with pathobiological variables, including: (1) patient age, sex, tumor size, histological type and grade, invasion depth, vascular invasion, perineural invasion and lymph node status; (2) the Ki-67 labeling index in 100 gastric carcinomas; and (3) the DNA ploidy pattern, S phase fraction (SPF), and the proliferation index (PI) in 84 cases using flow cytometry. The positive rate of p53 staining was 48% and the p53 immunoreactivity was independent of variable clinicopathologic factors. No correlation was made between the Ki-67 labeling index with p53 immunostaining and DNA ploidy parameters. Aneuploidy rate was slightly higher in the p53 positive group (55.6%) than the p53 negative group (44.4%)(p=0.097). The mean values of SPF and PI were significantly higher in the p53 protein positive group. Aneuploidy was more often observed in the intestinal type (p=0.038), advanced gastric carcinoma (p=0.015) and lymph node positive group(p=0.039). The above results suggest that although the p53 protein overexpression has no significant correlation with pathological factors and the Ki-67 labeling index, it may play an important role in tumor cell proliferation. Since p53 protein overexpression was slightly higher in the aneuploidy group showing significant correlation with poor prognostic parameters, it is thought that re-evaluation of the p53 mutation by molecular biological study is needed.

The purpose of this study was to describe the luminal development of the murine eustachian tube and middle ear. Thirty specimens, aging from gestational day 11 to postnatal day 21, were investigated through the light microscopic observations. The present study also used digitizer, computer, and serially sectioned temporal bone specimens for three-dimensional reconstruction to measure the volume of the eustachian tube and middle ear cavity at different gestational and postnatal ages. The first pharyngeal pouch elongated during gestational day 12 to form the tubotympanic recess. Between gestational day 13 and 14 this tubotympanic recess extended to the middle ear area. A rapid increment in the volume of the tubotympanic recess was noted between gestational day 15 and 16. At this age, a definite division of the tubotympanic recess into the eustachian tube and middle ear cavity was observed. During the postnatal period, the maximum change of the middle ear volume was noted on postnatal day 11 when the mesenchymal tissue in the middle ear cavity disappeared completely.

Retroviral vector provide a highly efficient method for gene transfer into eukaryotic cells. This vector system can be divided into two components; the retroviral vector itself and the retroviral packaging cell line. The key improvement in the design of these two components are. focused on two aspects; the reduction of helper virus production and high titer-virus. We used PA317 for retrovirus packaging cell line, for its high producibility of viral titer, To test the ability of the vectors to generate high titer-virus, we have chosen four different retroviral vectors; LN, LNSX, LNCX and LXSN. To test easily the viral titer, we have made recombinant construction with CD4 and CD8, checked their viral titer and stained their surface expression. LXSN which contain SV40 early promoter in front of leo gene showed best results in viral transient transfection assay, dot blot assay and surface expression. In addition, recombinant containing CD8 generally showed much higher viral titration and surface expression than CD4.

PURPOSE: This study was designed to investigate the body-image and quality of life in breast cancer patients with mastectomy. METHODS: Data were obtained by self-reported questionaries from 110 patients undergone mastectomy from August 1 to 31, 2007. And data were analyzed using SPSS/PC WIN 12.0 program and frequency, percentage, mean, minimum, maximum, t-test, ANOVA, Scheffe test, Pearson's Correlation Coefficient were used. The results of the study were as follows; 1) Mean of Body image of the subjects was 52.54+/-6.67 (range of scale; 17 to 85). Mean of quality of life was 118.01+/-34.37 (range of scale; 0 to 10). 2) There was no significant difference with the score of body image by demographic and disease-related characteristics of subjects. 3) There was significant difference with the score of quality of life by the work type and economic status of subjects. 4) Relationship between body image and quality of life showed moderately strong positive correlation (r=0.408, p<0.0001). CONCLUSION: Mean of body image and of quality of life in mastectomy patients were moderate. Relationship between body image and quality of life showed moderately strong positive correlation. Therefore, for improving the quality of life, it is needed to improve body image in breast cancer patients with mastectomy.

In order to describe the developmental anatomy of the murine eustachian tube and its related structures, seventy six mice of ages ranging from gestational day 11 to postnatal day 21 were investigated through the light and electron microscopic observations. Development of the ciliated cells was seen concurrently in both the eustachian tube and middle ear on the 16 th gestation day, one day earlier than the epithelial secretory cells appeared in both the eustachian tube and middle ear. The number of ciliated cells and secretory cells increased rapidly after birth. Tubal glands were well identified with evidence of secretory activity around the time of birth. Thus, the findings of this study indicate that the mucociliary defense system starts to develop during the fetal stage and is well established immediately after birth.
