Squamous cell carcinoma has occasionally been encountered in orthopedic practice as a complication of chronic osteomyelitis, burn scar and other lesions. The possible occurrence of this secondary change impose difficulty in the diagnosis and management of chronic orthopedic diseases. During 11 years from 1966 to 1976, 16 cases of squamous cell carcinoma were confirmed by histopathological examination and the results of clinical observation on them are summarized here. l. Of 16 patients, men were 15 and woman one. Their average age was 51.3 years 2. The primary lesions in which this malignancy developed were osteomyelitis (5 cases), and scar (5 cases), and scar after extensive laceration (2 cases). In one case no primary lesion was present. 3. Average duration of symptomatology of the primary lesion was 35.4 years in osteomyelitis and 31.2 yeary in burnscar. 4. Location of the lesion was in lower extremity in 15 cases, eight of which were in the leg. 5. Methods of treatment undertaken were; amputation (10 cases), chemotherapy (2 cases), chemotherapy and irradation (1 case). In three no treatment was done because of refusal. 6. The follow-up study was possible in five of them. Of four cases amputated, one was well alive for two years after ablation with no evidence of metastasis, the others two showed spread, to inguinal nodes in one and ribs in the other, after two years and the fourth died of unknown disease after two years. The fifth died, after initial remission with chemotherpy and irradation, of lung cancer after two years.

Electrical conductivity of eyeball replaced with vitreous substitutes were also measured in both the non-enucleated and enucleated eye. The study of correlation between the electroretinogram and conductivity of eyeball to be replaced with vitreous substitutes was also evaluated. The electrical conductivity of each vitreous replacement was shown 74.5% in vitreous, 77.5% in saline, 100% in air and silicone oil respectively relative to standard material -1.5 battery, 100%. There was no difference of conductivity between the enucleated eye and non-enucleated eye. There were no correlation between the ERG amplitude and conductivity. As a result of experiments, the decrease in amplitude is suggested as a damage of retina by manipulation and surgery rather than decrease of conductivity with vitreous replacements.

BACKGROUND: To evaluate depressure effect and safety of delapril, a new ACE inhibitor, in Korea. METHOD: Thirty three patients, aged 37-69, with mild to moderate essential hypertension were first observed for 2 weeks with placebo followed by administration of 15mg of delapril twice daily for 2 weeks, then doubled dosage to 30mg b.i.d. and combined with 25mg of dihydrochlorothiazide if optimal BP were not obtained at the end of 4th week, continued the same dose until the end of 10 week's trial period. RESULT: BP dropped 15/9mmHg inaverage at the end of 10th week rewarding 70% of cumulative effectiveness. Most frequent side reaction was dry cough, occurred in 9% of patients followed by chest tightness, headache, constipation and transient elevation of GPT. CONCLUSION: Delapril 15-30mg twice daily as monotheraphy or combined with diuretics is well tolerated and effective in the treatment of mild to moderate essential hypertension.

Tissue expansion in breast reconstruction is a invaluable alternative surgical procedure. the advent of permanent expander prosthesis eliminated a second operative procedure for removal of the expander and replacement with another permanent implant. When we consider the choice of method for breast reconstruction, we have to take account of the extent of mastectomy, past-medical history of the patient, timing of operation, and patient's motivation. It is still accepted that autogenous Breast reconstruction is the best choice of the mothed. As autogenous breast reconstruction increase in popularity, however, it requires longer operation time, more complicated technique, and careful attention to donor site. Autogenous breast reconstruction is also not good candidate for the patients who have diabetes, vascular disease, smoking, obesity, previous history of cesarean section, or further pregnancy planning. We have performed 10 immediate breast reconstructions after modified radical mastectomy using the permanent expander prosthesis, manufactured by Mentor corporation. Among these cases, 8 patients underwent cesarean section and 2 patients pregnancy. Although this method has advantages of simple technique, minimal morbidity, and low cost, it has some limitations for orientals. First, it is inevitable in superior fullness of the reconstructed breast because of round shape of the expander. Second, it is difficult to get ptotic breast because of thick and inelastic characteristics of oriental skin. Third, the ratio of expander base to projection is not appropriate for orientals because of their smaller chest size. We experienced 2 cases of spontaneous deflation for its manufactural defect itself. In our experience, we would like to suggest that new type of permanent expander prosthesis should be innovated.

PROPOSE: Body composition by bioelectrical impedance analysis (BIA) is a very useful method of analysing body composition. BIA is non-invasive, inexpensive, nonhazaedous and reproducible technique. The aim of this study was to determine the level of agreement between body composition measurement by BIA and dual-energy X-ray absorptiometry (DEXA). METHODS: Data was examined in 100 children (male 58; female 42), who visited Pusan National Hospital. Weight (kg) and height (cm) were measured, and body compositions were analyzed with fat mass, lean body mass, body fat percent by BIA and DEXA methods. RESULTS: Comparison of the DEXA and BIA methods showed highly statistically significant correlations in measurement of human body composition (fat mass, lean body mass, body fat percent). CONCLUSION: BIA should be considered as the method of choice in measurement of human body composition, since it's non-invasive, reliable, rapid, nonhazaedous and inexpensive, using portable equipment.

Activation of T cells for an immune response requires the participation of antigen presenting cells that express class II major histocompatibility complex gene products on their surface. As far as we know, there is no study on the agerelated changes of ED2 immunoreactive macrophages and MHC class II immunoreactive dendritic cells in the normal rat brain. The aim of the present study is to investigate the age-related changes of dendritic cells and macrophages in rat brain. The distribution and morphology of the macrophages and dendritic cells in the rat brain were studied from the 1 month-, 12 month- and 24 month-old rats by means of immunohistochemical methods using anti-rat MHC class II and anti-rat ED2 monoclonal antibodies. Antigen presenting cells were observed in choroid plexuses and white matter of the rat brain. The numbers of antigen presenting cells gradually increased with age. At all age stages and regions of the rat brain, the numbers of ED2 immunoreactive macrophages was higher than that of MHC class II immunoreactive dendritic cells. According as age increases, shapes of antigen presenting cells became more complex and aggregated together. In conclusion, the above results suggest that the increases of the number and the changes of the morphology in two kinds of the antigen-presenting cells, MHC class II-immunoreactive dendritic cells and ED2-immunoreactive macrophages, with age may influence on effects of cell-mediated immune responses.
