  • The nuclear phosphoprotein p53 is expressed in all normal cells and appears to function in cell cycle regulation. Abnormally high levels of the protein are found in many different types of cancer. In human cancer overexpression of p53 is associated with point mutations within highly conserved regions of p53 gene. These altered genes encode stable p53 proteins that can detected by standard immunocytochemical techniques unable to detect rapidly degraded wild-type protein. Using of a monoclonal antibody to p53 antigen, immunocytochemical analysis of 29 squamous cell carcinomas of tongue(n= 19) and tonsil(n= 10) was performed. Non-tumor nuclei showed all negative reactivity. Positive reactivity was found in 4/29(13.8%)of SCCs of tongue and tonsil. In sizes of primary tumor, the cases over 4cm showed more positive reactivity than the cases under 4cm(p < 0.05). There was no stastical correlation between the reactivity and histopathologic grades, the primary sites of tumor or the presence of cervical metastasis.

  • Purpose : To verify radiological changes of limb salvage operation using tumor prosthesis. Materials and Methods : Sixty-nine cases which used tumor prosthesis were reviewed. They have been followed up for average four years and nine months. We evaluated radiographs by ISOLS(International Symposium On Limb Salvage) radiological implants evaluation system immediate postoperatively, at postoperative 1 year and last follow-up. After converting 'excellent, good, fair, poor' to '4, 3, 2, 1' for stastical analysis, data were analyzed according to the use of cement, anatomical sites, diagnosis implant designs and age (<20 year vs. ${\geq}$20 year) using t-test and ANOVA. Results : The outcomes of cemented type prostheses were superior in remodelling and interface but inferior in anchorage. The scores of proximal femur and distal tibia were worse in bone remodelling. Osteosarcoma group had lower scores in anchorage and implant articular problem. There were no significant differences according to four different implant designs and age. Conclusion : In the intermediate term follow-up radiological evaluation, cemented type prosthesis were better in the aspects of bony resorption and osteolysis, and cementless one in anchorage. Distal femur and proximal tibia have higher scores in bony resorption, and osteosarcoma was worse tumor entity in anchorage and articular problem, and chemotherapy may be the cause.

  • Febrile morbidity after cesarean section is one of the major problems in obstetric practice. This morbidity is most often due to endometritis. Although parenteral prophylactic antibiotics or antibiotic irrigation has been reported to reduce the incidence of endometritis after cesarean section, its incidence remains high. Among the patients who were undergoing cesarean section at Yeungnam University Hospital from the beginning of March, 1985, three group were evaluated in the orders. 1) 30 cases as intrauterine irrigation group with cephradine solution, 2) 35 cases as intravenous injection group with cephradine, 3) 35 cases as control group are neither irrigated nor injected. Febrile morbidity was also evaluated by means of a fever index. The incidence of clinically diagnosed endometritis in the three group were 6.7%, 2.9%, and 22.9%. As these results, two study groups were markedly reduced the incidence of endometritis than control group. There was no significant difference between the intrauterine irrigation with cephradine and control, but significant difference between the intravenous cephradine injection and control (P<0.05). With the results of fever index analysis, both prophylactic intrauterine irrigation and intravenous injection markedly reduce the incidence of endometritis after cesarean section with stastical significance (P<0.05), and also markedly reduce the febrile degree.
