Various techniques for treatment of large bone defects have been reported, instead of using autogenous bone graft. The author have applied and explored for bone repair with polyglactin 910 mesh and fresh fascia late. Full thickness 8x8mm bone defects were made on the frontoparietal bone of rabbits and group 1 defect was covered with polyglactin 910 and group 2 defects with fresh fascia late, but group 3 and 4 were not covered. However the periosteum was left on group 4 but it was not left on group 3. Samples were taken from the operation site for clinical and histological examinations on 2, 4, 8 and 12 weeks after operation, repetitively. The results were as follows ; 1. On the group 1, where ployglactin 910 mesh had been placed, the defects taken in 2, 4 ,8, 12 weeks after operation disclosed osseous regeneration with newly formed bone but the thickness was much less than the original bone. 2. On the group 2, where fresh fascia rata had been placed, the defects taken in 2, 4, 8, 12 weeks after operation disclosed same pattern of group 1. 3. On the group 3 and 4, where membrane had not been placed, the majority of the defects consisted of connective tissue and muscles. 4. On the group 1, resorption of polyglactin 910 mesh was completed after 4 weeks, but on the group 2, the fascial rata still remained intact.

We report a case of hereditary trichilemmal cyst with proliferating trichilemmal tumor in a 64-year-oid man, who has generalized 157, variable sized firm cutaneous nodules for 40 years. The cystic nodules are chiefly located on the scalp and trunk which showed characteristic histopathologieal findings of trichilemmal cyst and proliferating trichilemmal tumors. His son also has multiple trichilemmal cysts and his mother seems to have had clinically similar lesions. The patient and his son were treated with surgical excision and therapeutic trial of oral isotretinoin for 2 months. Isotretionoin was ineffective in the patient, but the lesions of his son were decreased in size.

Clinical survey was performed on 413 cases of twin pregnancies and their 816 twin babies who were born at IlSin Christian Hospital during 5years from January 1987 to December 1991. The result of study was as follows: 1) there was 413 twin pregnancies among 40,711 deliveries, so the incidence of twins was 1:98.6. Average male-female sex ratio of twins was 1.3:1, same sex pairs rate was 86% and different sex ratio was 14%. 2) The incidence of relation with maternal age was highest between 25 years old and 29 years old but the ratio of twin delivery to total delivery was 0.9% so, was not higher than other age group. 3) The incidence of relation with maternal parity was highest at first pregnancy but the ratio of twin delivery to total delivery was highest at second pregnancies. 4) Normal birth weight infants were 45.7%, low birth weight infants were 54.3% and very low birth weight infants was 9.3%. Fullt-erm infants were 63.7% and prematurity were 35.4%. 5) The incidence of feto-fetal transfusion was 7.3%. 6) Perinatal death rate was 76.3 and was more higher in second babies. The most common cause of perinatal death was prematurity, followed by respiratory complication, congenital anomaly, infection and asphyxia. Still-births were 8 cases.

The prevalence of dermographism in 96 patients of acute or chronic urticaria was studied using dermographic tester. The results were summarized as follows : 1. The prevalence rate of dermographism in acute or chronic urticaria was 26.0% (25/96). 2. Dermographism was more common in acute or chronic urticaria than in the general population(p<0.005). 3. There was no significant difference in the prevalence rate of dermographiam between acute and chronic urticaria. 4. The prevalence rate of dermographism was not significantly correlated with the level of serum IgE.

The skin manifestations of secondary syphilis, termed syphilid, show macular, papular and papulosquamous rashes in most cases, but may show lots of other clinical findings. We report a case of syphitid simulating purpura annulsris telangieitodes in 25-year-old male who had a history of genital ulcer 2 months ago. The skin lesion showed diffuse erythematous, 1-3 cm sized, telangiectatic annular patchea and purpuric plaques on both lower extremities and discrete papulosquamous rashes on both soles. The results of the serologic test for syphili was found to be reactive to 32 dilution in serum VDRL test and positive in serum TPHA test. Histovathologically, we could observe the obscuring of dermoepidermal juction, coat-sleeve-like perivascular infiltrate composed of mononuclear cells and a few plasma cells, and endothelial swellings. Afte the treatment with benzathine penicillin G, the titer of serurn VDRL test was decreased abruptly to 4 dilution and the skin lesions disappeared completely.

Recently, [I-123]IPT SPECT has been used for early diagnosis of Parkinson's patients(PP) by imaging dopamine transporters. The dynamic time activity curves in basal ganglia(BG) and occipital cortex(OCC) without blood samples were obtained for 2 hours. These data were then used to measure dopamine transporters by operationally defined ratio methods of (BG-OCC)/OCC at 2 hrs, binding potential Rv=k3/k4 using graphic method or RA= (ABBG-ABOCC)/ABOCC for 2 hrs, where ABBG represents accumulated binding activity in basal ganglia(integral 0 120minBG(t)dt) and ABOCC represents accumulated binding activity in occipital cortex(integral 0 120minBG(t)dt). The purpose of this study was to examine the IPT pharmacokinetics and investigate the usefulness of simplified methods of (BG-OCC)/OCC, RA, and RA which are often assumed that these values reflect the true values of k3/k4. The rate constants K1, k2, k3 and k4 to be used for simulations were derived using [I-123]IPT SPECT and aterialized blood data with a standard three compartmental model. The sensitivities and time activity curves in BG and OCC were computed by changing K1 and k3(only BG) for every 5min over 2 hours. The values (BG-OCC)/OCC, RA, and Rv were then computed from the time activity curves and the linear regression analysis was used to measure the accuracies of these methods. The rate constants K1, k2, k3, k4 at BG and OCC were 1.26+/-5.41%, 0.044+/-19.58%, 0.031+/-24.36%, 0.008+/-22.78% and 1.36+/-4.76%, 0.170+/-6.89%, 0.007+/-23.89%, 0.007+/-45.09%, respectively. The Sensitivities for ((delta S/S)/(delta k3/k3)) and ((delta S/delta S)/(delta K1/K1)) at 30min and 120min were measured as (0.19, 0.50) and (0.61, 0.23), respectively. The correlation coefficients and slopes of ((BG-OCC)/OCC, RA, and Rv) with k3/k4 were (0.98, 1.00, 0.99) and (1.76, 0.47, 1.25), respectively. These simulation results indicate that a late [1-123]IPT SPECT image may represent the distribution of the dopamine transporters. Good correlations were shown between (BG-OCC)/OCC, RA or Rv and true k3/k4,, although the slopes between them were not unity. Pharmacokinetic computer simulations may be very useful technique in studying dopamine transpoter systems.

Barts syndrome was desrribed by Bart(Bart et al, 1966) with hereditary congenital localized absence of skin from the lovrer legs associated with blistering of the sun and mouth and nail abnormalities. A newborn girl presented with a congenital localized absence of skn over both shins & dorsa of both feet which were covered with the thin, translucent, brown red glistening membranes. A number of blisters were seen on the back, thighs upper extremities, and both 2rd toe nails were absent. Electron microscopic examination of defected skin revealed dermo-epidermal . paration with focal disruption of basal lamina.
