Neoplasms showing both carcinomatous and sarcomatous features are well established, and have been reported in practically every organ where carcinoma can occur. But the difference in terminology and difficulties in histopathologic interpretation have hampered adequate understanding of these neoplasms. We report a case of carcinosarcoma in the recurrent form of serous cystadenocarcinoma of the ovary. The patient was a 64-year-old female who underwent total hysterectomy and bilateral salpingoophorectomy three years ago, due to perforated papillary serous cysta denocarcinoma of the right ovary. Recurrent pelvic masses contained both carcinomatous and sarcomatous components. Morphological transition between carcinomatous and sarcomatous components, and epithelial characteristics in the sarcomatous component by immunohistochemistry were recognized. We postulate the histopathogenetic mechanism based on the phenotypic conversion of carcinoma into sarcoma in the carcinosarcoma.

A case of an ovarian mucinous cystadenocarcinoma with mural nodules of anaplastic carcinoma is reported. The patient was a 46-year-old female with a right ovarian cystic mass and underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. The patient died of the disease in five months. Macroscopically, the right ovarian cyst wall contained numerous well-demarcated mural nodules. Histologically, the cysts were mucinous cystadenocarcinoma, and the nodules were composed of sarcoma-like spindle and polygonal cells with atypia and numerous mitoses. Spindle cells in the mural nodule showed epithelial characteristics by electron microscopy and immunohistochemistry. This case supports an epithelial origin of the mural nodule of anaplastic carcinoma in ovarian mucinous tumors.

STUDY DESIGN: The purpose of this study was to determine whether facet joint orientation and/or tropism influences the prevalence of disc degeneration in MRI in young patients. OBJECTIVE: 41 patients with disc degeneration disease including HNP in MRI were assesed on facet joint angles and tropism between 18 and 30 years old. SUMMARY OF BACKGROUD DATA: The patients who had back pain had association between disc degeneration and facet tropism in adults. But some authors have suggested that facet tropism has no clinical relevance. Physiologic aging and premature disc degeneration induce a gradual loss of water and proteoglycan from nucleus pulposus. METHODS: We reviewed the 41 MRI of lumbar spine with disc degeneration and measured facet joint angles on the mid-disc cut, which was parallel to inferior vertebral end-plate of superior vertebra. In simple X-ray, we reviewed relation between the transitional vertebrae and disc degeneration. It was analyzed statistically the facet joint angles and facet tropism in each levels. RESULTS: The mean facet angles was more increased in upper vertebral facet joints but statistically nonspecific. The facet tropism was not significant in all lumbar levels and the effects of transitional vertebrae on disc degeneration were ignorable and unclear. CONCLUSIONS: No statistical relationship was found among the magnitude of the angle and facet tropism and the presence of disc degeneration at any levels in young patients.

Since adult human skin can be grown in chernically defined medium without serum, the skin organ culture has gained a great interest as a method for studies concerning skin biology, pharmacology and toxicology. however, serum supplementation has extensively been used to improve the viahility of tissue culture. This study was undertaken to evaluate the effect of serum on the histologic changes ohserved during the organ culture of the normal human skin. The general architecture of the skin was well maintained for 6 days with or without seru. After then, fetal calf serum or autologous human serum was found to enhance the viability of the epidermis. A confluent layer of necrotic spinous ceils was ovserved earlier and more widespread without serum. The addition of serum had an impressive effect on epibolization. In the absenee of serum, the formation of the epibolus was not only minimal, but also, susceptible to degeneration, and no epibolus remained at 10 days rif incubation. No difference can be found between fetal calf serm and autologous human serum in the formation of the epibolus. There was no favorable effect of serum on the formation of new stratum corneum. The thickness of new straturn corneum increased in parallel with the number of parakeratatic cells, increasing most rapidly between 6 and 8 days of incubation. Parakeratosis was more prominent in the presence of serurn.

BACKGROUND: Oncogenes and EGF-Receptor(EGFR) may be involved n different stages of the multistep carcinogenesis process. A specific pattern of karyotypic abnormalities in solid tumors can be detected by cytogenetic methods. OBJECTIVE: This study is intnded to observe the cytomolecular kiologic chracterization of c-myc, erb B and EGFR genes in squasnous cell carcinoma(SCC) of the skin and cervix. METHODS: We have eytogenet,ically examined the short-term culturs from SCC. The rearrangement, amplification or expressi.on of erb B, c-myc, and EGFR genes were studied by Southern blot, analysis of genomic DNA and by slot blot analysis of tota! RNA extracted from biopsies of normal skin and SCC tissues. EGFR expression was examined immunohistochemially using monoclonal antibodies and the localizat,ion of the c-myc oncogene mRNA by in situ hybridization. RESULTS: A remarkably structural aberration was del 6(q21-qter) counted 20 metaphases among 28 metaphases ana1yzed. In nunierical aberration, all chromosomes were lost or gained randomly. Amenploid including triploid and tetraploid were observed in 8 metaphases, 6 tumor cells contained marker chromosome. In Southern blot analysis, rearrangement and amglificaton of EGFR in primary squamous cell carcinoma of cervix uteri and skin respectively. In slot blot analysis, the levels of c-myc, erb B and EGFR mRNA increaaed respectively 3.5, 2.5 and 2.8 times in SCC when compared to normal tissues. In immunoperoxidase stain, EGFR was present, in SCC where keratinocytes with strong cyto-plasmic staining but no membr, line labelling, where as in normal skin the were primarily present in t,he membrane and cytoplasm of basal cells. In situ hybridization with c-myc cDNAs allowed detection of grains representative of biotin labelled cDNA-mRNA hybrids in the frozden section of SCC tissues. CONCLUSION: These results suggest that specific patterns of karyotypir abnormalites, rearrangement, or amplification of EGFR gene, and overexpression of oncogenes and EGFR gene may be associated with the carcinogenesis of SCC.

OBJECTIVE: To assess the effect of recombinant human leukemia inhibitory factor on in vitro development of 1-cell ICR mouse embryo. MATERIALS AND METHOD: ICR mice were superovulated with PMSG/hCG and 1-cell stage mouse embryos were recruited. 1-cell mouse embryo were cocultured on human oviductal cells in a CO2 incubator (coculture group) and were cultured on 0.4% BSA+HTF media (control group). And anti-hLIF Ab was added the cocultured group in a different concentration (1pg, 10pg, 100pg, 1ng) and developmental rate was compaired to the control group, and rhLIF was added to the preincubated 0.4% BSA+HTF media in a different concentration (2000U, 1000U, 100U, 10U) and its developmental rate was compaired to group which was cultured on 0.4% BSA+HTF media only. RESULT: 1. The cleavage rate of 2-cell mouse embryo co-cultured with human tubal epithelial cell was significantly higher than that of cultured with media alone (HTF with 0.4% BSA) (p<0.05). 2. When LIF antibody was added to the medium with human tubal epitherlial cell, the mouse embryo could not cleave more than 2-cell in 1 ng of LIF antibody, and less than 1 ng, the cleavage rate was lower than cultured without LIF antibody group(p<0.05). 3. Two cell blocked ICR mouse embryos were developed into four cells under LIF(p<0.05), but no further development was observed. CONCLUSIONS: These results shows that LIF enhances the development of preimplantation embryo, and when rhLIF is applicated in vitro, it has positive effects on the development of early mouse embryo and can help overcoming the two-cell block.

We describe a 8-year-old girl with erythrokeratodermia varibilis (EKV). This diagnosis was supported by erythematous, configurate patches over the entire body. Their size, shape and location varyed with enviromental factors and emotional state. In addition, well defined brownish, hyperkeratotic plaques were scattered over the trunk and extremities. Also, this patient had alopecia universalis, which is not typical of EKV. Etretinate therapy resulted in an almost complete clinical clearing of the plaques; however, her alopecia universalis and erythematous lesions were not affected.

Human papillomavirus (HPV) 16/18 is a causative agent of uterine cervical carcinoma. HPV 16/18 can alter cell cycle regulation through apoptosis. Bcl-2 is an important regulatory gene of apoptosis. A study was done to evaluate the relation between HPV 16/18 and bcl-2 and apoptosis in 21 cases of carcinoma in-situ (CIS), 5 cases of microinvasive carcinoma and 23 cases of invasive squamous cell carcinoma. HPV 16/18 was detected by hybrid capture system (HCS), bcl-2 protein by immunohistochemical method and apoptosis by using the hematoxylin-eosin stained slide. The results were as follows: Expression of the bcl-2 protein was 43% (9/21) in CIS and 26% (6/23) in invasive carcinoma. Expression of the bcl-2 protein was 42% (5/12) in CIS with HPV 16/18 infection, 44% in CIS without HPV 16/18 infection, 20% (2/10) in invasive carcinoma with HPV 16/18 infection and 31% (4/13) in invasive carcinoma without HPV 16/18 infection. Mean apoptotic index (mAI) was 3.36 in CIS, 5.23 in microinvasive and 6.25 in invasive carcinoma. mAI was 3.66 in CIS with HPV 16/18 infection, 2.86 in CIS without HPV 16/18 infection, 6.18 in invasive carcinoma with HPV 16/18 infection and 6.30 in invasive carcinoma without HPV 16/18 infection. Based on these results, we conclude that there are no correlation between HPV infection and bcl-2, and between HPV infection and apoptosis in invasive and in situ carcinoma of the uterine cervix, and apoptosis is increased according to tumor progression.

OBJECTIVES: The purpose of this study was to reveal psychological traits, risk factors, and predictors of the military maladjusted group. In addition, we attempted to compare the correlation of temperament, character profile, and resilience between maladjusted and adjusted groups. METHODS: A total of 166 maladjusted soldiers who joined the green camp of three divisions and 125 adjusted soldiers participated in the survey from July to December 2013. As self-report questionnaire methods, Beck Anxiety Inventory, Beck Depression Inventory (BDI), and the Korean version of the Connor-Davidson Resilience Scale, Temperament and Character Inventory (TCI) were used. T-test, binary logistic regression analysis, Pearson's correlation, and multiple regression analysis were used as analytical methods. RESULTS: The maladjusted group showed a high level of anxiety, depression, and Harm Avoidance and a low level of resilience, Reward Dependence (RD), Persistence, Self-Directedness, and Cooperativeness compared with the adjusted group. BDI and RD were found to be statistically significant for prediction of military maladjustment. Higher correlation between resilience and TCI was observed for the maladjusted group, but not the adjusted group. CONCLUSION: We suggest that a high depression level and a low RD level should be included as predictors among target symptoms for development of psychological treatment for the maladjusted group. In addition, we suggest that the level of resilience can affect correlation of resilience with TCI.
