The authors performed a retrospective matched-pair study for 54 uncemented total hip arthroplasties which were performed in management of avascular necrosis of femoral head from July, 1989 to May, 1991 to investigate what kind of stem is better between Anatomic stem as a proximal filling stem and Harris-Galante stem as a distal filling stem. The results were as followings: 1. Clinical results of Anatomic group were slightly better than those of Harris-Galante group in terms of incidence of thigh pain, groin or buttock pain and final functional score of hip. 2. Incidence of radiolucency around femoral stem in Harris-Galante group was higher than that in Anatomic group, especially in zone I, V of anteroposterior view and in zone IV of lateral view, which were statistically significant(p < 0.05). 3. The incidence of vertical subsidence of femoral stem in Harris-Galante group was significantly higher than that in Anatomic group(p < 0.05) and the average distance of subsidence was 3.2mm. 4. The incidence of endosteal osteolysis and bone resorption in Harris-Galante group was higher than that in Anatomic group. 5. In overall view, clinical and radiographic results of Anatomic group were better than those of Harris-Galante group.

There have been so many methods described for the correction of the deviated noses but it is difficult to get satisfactory results and recurrence rate is high. There is no exact explanation why the recurrences are so high and no estabished guides for techniques according to the surgical pathology. We found the classical swinging door technique effective in cases where the caudal septum deviated from the midline. However, where the caudal septum and the tip stay in the midline, scoring or submucosal resection do not work well enough to cortet them. We used the reverse swinging door technique of our own. After elevation of mucoperichonodrium, we did sagittal section in the posterior septum and moved the septum to the midline on the pivot point of the caudal septum and. The gap created in the posterior portion of the septum were filed with bone grafts, cartilage grafts or Medopor, which were sutured to the septum, We did this technique with or without osteotmies in 56 deviated noses for last 5 years. The results were very satisfactory and there was no complication.

BACKGROUND: Allergic diseases are characterized by immediate - and late - phase reactions to various allergens by the selective activation of a subset of CD4 + T cells. In response to allergen, T cells isolated from atopic donors are biased to low levels of IFN - y and high levels of IL - 4, and vice versa by T cells from non - atopic donor. Objective : The aim of this study was to evaluate the patterns of IL - 4 and IFN - y production after Der p I stimulation and the effect on the cytokine production from T cells by budesonide, disodium cromoglycate and cyclosporin A in atopic and non - atopic individuals. MATERIAL AND METHOD: Seven Der p I specific atopic and 7 non - atopic individuals were selected. We decided the 50% inhibiting concentration of each immunomodulator by lymphocyte proliferation assay, and measured their effects on the cytokine production in vitro by intracellular IL - 4, IFN - y staining and flow cytometry. Results and CONCLUSION: There was significant difference on stimulation index ( SI ) of production of IFN - y as well as IL-4 after Der p I stimulation between atopic and non-atopic individuals ( IL - 4 ; 1.57 +/- 0.7 : 0.98 +/- 0.2, p = 0.026, IFN - r : 1.45 +/- 0.5 : 0.95 +/- 0.2, p = 0.048 ). The synthesis of IL - 4, and IFN - r were significantly inhibited after the stimulation of every immunomodulators in atopic individuals, DSCG couldnt inhibit IL - 4 and IFN - r in nonatopic individuals. There was no significant difference in the inhibiting effect of these immunomodulators in both of them.

OBJECTIVE: To investigate the bone mineral density(BMD) in Korean postmenopausal women. METHODS: We performed the retrospective study for 1,508 postmenopausal women who had menopause after 40 years of age and didn't take any hormonal agent before measuring bone mineral density. Spinal and femur neck BMD were measured using dual energy X-ray absorptiometry(DXA, Lunar Co.). RESULTS: The mean age of the study subjects was 53.7+/-5.7 years and the average BMD of the lumbar spine(L2-L4; L24) and femur neck(FN) were 0.996+/-0.173 g/cm(2) and 0.821+/-0.133 g/cm(2), respectively. Of all subjects, 44.1%(665/1,508) had osteopenia and 14.7%(222/1,508) were already osteoporotic. The prevalence of osteoporosis increased with age; 5.2% in 41-50 years of age, 15.6% in fifties, 32.5% in sixties, and 45.5% in over 70 years of age. There was no significant difference in the age-adjusted BMD between naturally menopausal women(n=828) and surgically menopausal women(n=78). The mean age at menopause of surgically menopausal women was significantly younger than that of naturally menopausal women(47.6+/-3.6 vs 49.2+/-3.5). Duration of menopause, body weight, and height were revealed to be the significant risk factors for osteoporosis. The annual bone loss rates in lumbar spine and femur neck were 1.2% and 1.1% respectively in naturally menopausal women, and 1.5% and 1.2% in surgically menopausal women. CONCLUSIONS: This study established the BMD curve and regression equation in Korean postmenopausal women according to the causes of menopause. There was no significant difference in the mean BMD and the prevalence of osteoporosis between naturally and surgically menopausal women. Duration of menopause, body weight, and height were found to be the risk factors which influence the development of the osteoporosis. So the postmenopausal women who are at increased risks of developing osteoporosis need more active interventions for preventing the osteoporotic fracture.
