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.

We have retrospectively analyzed the clinical and radiological outcome in 22 cervical spondylotic myeloradiculopathy patients who underwent combined front anterior decompression and fusion) and back (open door laminoplasty) surgery between Mar. 1991 and Jan. 1995. Clinical symptoms were evaluated by Japanese Orthopaedic Association(JOA) score and the recovery rate. Plain radiogram and MIR were taken before and after surgery, and then the cervical curvature, change of body to canal ratio and the A-P compression ratio of the cord were measured and compared to the clinical symptoms. Results : The mean JOA score increased from 10.1±3.3 preoperatively to 14.7±1.4 at the final follow-up with a mean recovery rate of 64.4%. No patients deteriorated as a result of the combined procedure. Post-op. radiograms showed an increasement of body to ratios (average 0.69±0.09 pre-op. to 1.0±0.13 post-op.) and maintenance or recovery of cervical Lordosis. On MRI, the A-P compression ratios of the cord were increased with recovery of subarachnoid space after the operation in most cases (average 38.4±7.6 pre-op. to 55.7±7.2 post-op.). Conclusion : This combined procedure safely and effectively resulted in decompression of the spinal cord and good functional recovery in patients with 1) anterior and posterior pathology, 2) narrow spinal canal and large spondylotic bar or herniated disc encroaching the spinal canal more than 5mm, 3) narrow spinal canal and kyphotic deformity, 4) narrow spinal canal and segmental instability, 5) multisegmental cord compression and severe radiculopathy.

3.The Institutionalization of Public Hygiene in Korea, 1876-1910.

Korean Journal of Medical History 1995;4(1):23-35
On the whole, the major impetus for the institutionalization of public hygiene in Korea came from two directions. On one hand, the self-enlightened intellectuals had introduced a variety of Western ideas and theories on public hygiene since the mid-eighteenth century. On the other hand, Japan strongly influenced the modern systems of Korean health care and medical education, especially through Japanese efforts at the sanitary control of infectious diseases such as smallpox and cholera. The institutionalization of Korea's public hygiene in this period corresponded not to the high ideas of the progressive intellectuals but to the larger social and institutional changes caused by the major political events. Ideas of public hygiene were institutionalized as a powerful strategy of linking the imperial capital and colonial domains.

4.Moyamoya Disease: Difference of MR Findings between Children and Adults.
Journal of the Korean Radiological Society 1995;33(6):979-985
PURPOSE: To evaluate whether there are any differences in MR findings between the childhood and the adult moyamoya disease. MATERIALS AND METHODS: We compared the brain MR findings in 22 children (13 boys and 9 girls, 2-18 years of age) who had moyamoya disease with 15 adult patients (7 men and 8 women, 19-55 years of age). The MR findings were classified as parenchymal-(infarctions and intracranial hemorrhages) and vascular abnormalities (intracranial vascular patency and moyamoya vessels). The difference in each of these MR findings was analyzed using Chi-squaretest and Fisher's exact test (two-tailed). Out of 22 children, two children with normal MR finding were excluded from the statistical analysis. Moyamoya diseases were diagnosed angiographically in all adult patients. In children, they were diagnosed by MR imaging, MR angiography(6), and/or conventional cerebral angiography(18). RESULTS: In children, cerebral infarctions were observed in 20 of 22 patients (91%) (cortex 86%, periventricular white matter/centrum semiovale 32%, basal ganglia 10%). In two patients, there was no parenchymal abnormality. Intra-cranial hemorrhages were not demonstrated in any patients. In adults, intra-cranial hemorrhages(intracerebral hematoma, intraventricular hemorrhage, alone or combined) were demonstrated in 10 of 15 patients(67%). Cerebral infarctions with or without intracranial hemorrhage were detected in 10 of 15 patients(67%)(cortex 40%, periventricular white matter/centrum semiovale 53%, basal ganglia 20%). The difference in parenchymal abnormalities between the childhood and the adult moyamoya disease was statistically significant (p=0. 000164). There was no significant difference between the two groups with regard to the occlusive changes of the internal carotid and middle cerebral arteries or to moyamoya vessels(p> 0.01 ). CONCLUSION: This study could prove the fact that the principal clinical symptoms in the childhood moyamoya disease were due to cerebral infarction and those in the adult cases were due to infarction and intracranial hemorrhage. In addition, cortical infarction was more prevalent in children and infarction in periventricular white matter/centrum semivoale and basal ganglia was more frequentin adults. There was no significant difference in vascular abnormalities between the two groups.

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.

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.
