We report one case of aseptic necrosis of both talus which has developed without any evidence of previous trauma. Aseptic necrosis of the talus is known to occur after any trauma which result in iterruption the blood supply to talus. Atraumatic aseptic necrosis of talus is extremely rarre condition. Some cases of atraumatic aseptic necrosis of talus were repoted by some authers, in whom Garcia described the first case in 1928. Most of the reported atraumatic aseptic necrosis were due to long term steroid therapy for unrelated medical problems and others were related to Alcoholism, Sepsis and Tuber culosis. ln this case we think for it may be caused or contributed by steroid therapy.

We herein presented a case of persistent variant of Grovers disease in a 83-year old male. He had a rather extensive eruption of erythematous scaly papules, which had been profusely grouped but discretely distributed over 2 years or more. The histopathologic findings of two lesions in the same patient revealed mixture of various histologic patterns, patterns resembling Dariers disease, pemphigus vulgaris, Hailey-Hailey disease and spongiosis. The ultrastructural findings of Darier pattern should be essentially similar to those of Dariers disease and also be common to those observed in the early stages of other causes of focal acantholytic dyskeratosis. The patient had been treated with topical and intralesional steroid and oral 13-cis-isotretinoin, however, the lesions had been persisted only with partial improvement of clinical appearance and reduction of pruritus.

BACKGROUND: The HLA system is known to be the most polymorphic genetic system in human and there are characteristic racial differences in the distribution of HLA antigens, alleles, and haplotypes. This study was performed to examine the frequency of HLA antigens, alleles and haplotypes in Koreans. METHODS: Two thousand healthy Koreans registered for unrelated bone marrow donors were subject to the study. HLA-A, B and C antigens were typed by the serological method, and HLA-DR DNA typing (low resolution) was done by PCR and reverse hybridization. HLA allele and haplotype frequencies and linkage disequilibrium values were calculated by the maximun likelihood method using the computer program of the 11th International Histocompatibility Workshop. RESULTS: HLA antigens identified in 2000 Koreans were 14 in A locus, 33 in B locus, 8 in C locus and 12 in DR locus. Alleles showing frequencies of more than 10% in decreasing order of frequency In each HLA locus were A2, A24, A33, All, B44, B62; CBL, Cw3, Cwl, Cw7, DR4, DR2, DRl3, DR8, and DR9. Among A-B, C-B, B-DR 2-locus haplotypes, A33-B44, A30-B13, Al-B37, Cwl-B54, Cw4-B62, B7-DR1, B37-DR10 showed strong positive linkage disequilibrium (Chi-square > 1000). The most common A-B-DR haplotypes in Koreans occurring at frequency of more than 2% were A33-B44-DRl3 (4.8%), A33-B58-DRl3 (3.2%), A33-B44-DR7 (2.6%), All-B62-DR4 (2.3%), A24-B7-DR1 (2.3%), and A30-Bl3-DR7 (2.1%) Comparison of the distribution of A-B-DR haplotypes among east Asian populations reveals that Koreans are most close to Japanese, but show higher degree of polymorphism in the distribution of HLA haplotypes compared to Japanese. CONCLUSIONS: The results obtained in this study can be used as basic data for Koreans in the fields of organ transplantation, disease association studies and anthropologic studies.

Esthetic is one of the prime goal of the orthodontic treatment. The upper incisor position in important because it is decisive in balanced smile. This study was attempted to obtain the standards and equations on the esthetic upper incisor position. Lateral cephalometric radiographs of 66 Korean young adult females who were candidates of Miss Korea Beauty Contest were traced, measured and statistically analyzed. The results were as follows ; 1. The mean and standard deviation of the measurement for upper incisor position were obtained in the Korean Beauty. 2. Among the measurements of the axis of upper incisor, 1 to SN and 1 to FH were high1y correlated with FH-MP, ANB, FH-N Pag, Y-axis, but 1 to SN (Is-Pr) to present axial inclination of labial surface of upper Incisor didn't have any correlation with the measurements for dentofacial pattern. 3. Among the measurements for the vertical position of upper incisor, 1 to stom had low correlation with to measurements for dentofacial pattern and 1 to PP(mm) was highly correlated with the measurements for facial growth direction. 4. Sixteen multiple regression equations were established to predict upper incisor position balancing with dentofacial pattern. 5. It does not have much power of persuasion to predict esthetic upper incisor position from the measurements for dentofacial pattern.

The fashion of vascular anastomosis, end-to-end or end-to-side (E-to-S), are depended upon surgeon's preference or surgical situations. In E-to-S anastomosis two different methods of arteriotomy are applicable but it has been suggested the type, either elliptical or slit arteriotomy, play a different role in the flow hemodynamics. We thought that the difference is more considerable in microvascular surgery. This study examines the effects of elliptical versus slit arteriotomy on morphologic vessel patency. Twenty male Sprague-Dawley rats were divided into two groups of ten rats each. Both carotid arteries were selected as a experimental model. During the procedures the rat brain was tolerable to ischemia and all animals were survived after operations. The morphologic analysis of anastomosis site was through resin-casting method with scanning electromicroscopic examination. The results showed notable difference between two groups in three-dimensional morphology at two-month of operation. This difference may affect the flow hemodynamics and long-term vessel patency. In microvascular anastomosis, the mortpologic difference of the elliptical arteriotomy is worse than slit arteriotomy which compromises the vessel circumference.
