In 1970, Boutine introduced a alumina ceramic for cemented total hip replacement . A ceramic articulation thought to be superior to metal on polyethylene due to its extremely low coefficient of friction and its potential for resistance to wear. Mechanical failure of ceramic femoral head is rare. We report a case of fracture of ceramic femoral head, which occured after implantation of uncemented total hip replacement.

p53 gene mutation is commonly accepted to be associated with loss of negative cell cycle control and progression of tumors. The proliferative activity of tumor cells is considered to be a valuable indicator of tumor aggressiveness. This study is intended to compare p53 protein expression with cell proliferation rates in the ovarian epithelial tumors according to the various clinicopathological parameters. Immunohistochemistry using monoclonal p53 antibody (DO-1) and PCNA antibody (PC10) was applied to 56 cases of ovarian epithelial tumors including 17 cases of borderline tumor. The results were as follows. Both immunohistochemical staining of PCNA and p53 protein showed positive reactions confined to the nuclei of tumor cells. There were significant differences of p53 protein expression rates between borderline malignancies (11.8%) and cystadenocarcinomas (56.4%) of ovary. The expression rate of p53 protein was not significantly different according to the differentiation and the stage, but the cases of strong positive reaction to p53 protein were more frequently noted in the poorly differentiated and advanced staged tumors. The PCNA indices of p53 strong positive cases were higher than those of p53 weak positive cases. In summary, p53 protein and PCNA expression may be used as an adjuvant in differentiating borderline lesions from carcinomas of ovary and predicting their biological behaviors.

Fracture of the tibial shaft is one of the most common fractures of the long bones and frequently followed by malunion, delayed union and nonunion. We experienced the cases of further increase in the angulation after clinical union of the tibial shaft fractures treated by conservative method. So we analyzed 39 cases of tibial shaft fractures which were followed up from 12 weeks to 37 weeks after clinical union in adults. The results were as follows; l. 7 of the 39 cases(18%) showed the increase in the angulation, and all of them were male. 2. Increase in the angulation occurred more frequenlty in the comminuted fractures than simple fractures. 3. The increment of angulation was more marked in group of patients with higher angulation at the time of clinical union. 4. Increase in the angulation occurred more commonly in the cases not associated with fibula fracture than in the cases associated with fibula fracture. 5. Further increase in the angulation was less common in the cases in whom early weight bearing with PTB cast was started.

To evaluate the relationship between eating behavior and neurotic trait in middle school students, the authors applied eating scale, Middlesex Hospital Puestionaire and Zung's self-reting depression scale to 419 middle school students(male : 187, female : 232) in Taegu city in 1993. There was no significant relationship between weight devided groups. Female middle school students showed significant high scores(p<0.05) in all scales compared to male middle school students. The correlation between eating scale and the other two scales showed significant correlationship(p<0.05) Among psychosocial factors, the items related to dissatisfaction to present and future self image(each p<0.05, p<0.05), dissatisfaction to present environmental status(p<0.05) and dissatisfaction to future attitude showed significant high score in both sex. The item related to dissatisfaction to present interpersonal relationship (p<0.05) showed significant high score in male middle school students. The items related to eat consumption rate of 61-90% (p<0.05), unsatisfied to relationship with family(p<0.05), unsatisfied to childhood family atmosphere(p<0.05), unsatisfied to past self image(p<0.05) and unsatisfied to present relationship between parent(p<0.05) showed significant high score.

The effects and roles of social support and stressors (stressful life events and chronic strains) on psychosocial distress were examined in a model with data from a sample of the white-collar workers (N = 416) in Korea. The findings of this study present that mean levels of psychosocial distress were higher' in the female, youth, unmarried and divorced, and low economic status (monthly income). The analysis also shows that, as expected, stressful life and chronic strains as stressors are positively related to occurrence of psychosocial distress, and social support is negatively related to psychosocial distress. Further, the contribution of social support to predicting psychosocial distress is greater in magnitude than that of stressful events, chronic strains, and sociodemographic variables. There is no evidence that social support buffers the impacts of stressors on psychosocial distress, rather social support takes a role of main or direct effects on psychosocial distress. Therefore, the strength of the social support is an important and meaningful strategy to prevent from stress and mental, physical illness.

To evaluate the relationships among the c-erbB-2 oncogene expression, DNA ploidy and other prognostic factors, an immunohistochemical study of the c-erbB-2 oncogene product and flow cytometric analysis of DNA ploidy were performed in paraffin sections of 42 cases of ovarian carcinomas. The results were as follows: 1) The positive reaction for c-erbB-2 oncogene product was observed mainly along the cytoplasmic membrane, and occasionally within the cytoplasm of the tumor cells. 2) Overall the positivity of c-erbB-2 oncogene expression was 45.2% of the ovarian carcinomas. By the histological types, the positivity was 35.7% in serous carcinoma, 80.0% in mucinous carcinoma, and 45.2% in endometrioid carcinoma; by the degree of differentiation, 57.1% in well differentiated carcinoma, 40.0% in moderately differentiated, and 27.3% in poorly differentiated; by the nuclear grading, 58.3% in grade I, 52.6% in grade II, and 18.2 % in grade III; and by the clinical staging, 57.1% in stage I, 42.8% in stage II, and 35.0% in stage III. The expression of the c-erbB-2 oncogene in the ovarian carcinomas was higher in the tumors of good differentiation, of the lower nuclear grade and of the lower clinical stage. 3) The incidence of DNA aneuploidy in the cases positive for the c-erbB-2 oncogene expression(47.3%) was higher than that in the negative cases(31.4%). From the above results, therefore, it is suggested that the c-erbB-2 oncogene may be involved in the early stage of ovarian carcinogenesis. Also suggested is that ovarian carcinomas positive for the c-erbB-2 oncogene in the early stages may have higher probability of having a DNA aneuploid cell line during the progress of the tumors.
