Alleles and genotype frequencies and its distribution pattern for the highly polymorphic D1S80 locus were determined in a Korean population sample, especially in Kwangju and Chonnam, by using PCR followed by agarose gel electrophoresis with ethidium bromide staining, a procedure called the amplified-fragment-length polymorphism(Amp-FLP) technique. And the data were compared with the alleles and genotype frequencies of Finnish population, North American Caucasian, and Korean population(Seoul) which had been reported. In 203 unrelated Korean individuals 27 alleles and 84 genotypes were observed. The highest allele frequency was in allele M24(0.128) and tne next orders were inalleles M18(0.126), M29, M30, M31, and M28 and the other alleles showed relatively low frequencies. The highest frequency of genotype was in M18/M24 and the next order frequencies were M18/M30, M19/M27 M29/M29, and M18/M29. The homozyous genotypes were in 9 alleles such as M29, M24, M31, and M18, and most of heterozygous genotypes were composed of alleles of each homozygous genotypes and /or the other alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals were included. The VNTR D1S80 locus demonstrated a heterozygosity of 0.872. From the above results, VNTR D1S80 locus may be a powerful locus to identify individuals, however, the allele frequencies was not closely related to the genotype pattern, and the alleles of homozygous genotypes influenced on the chance of the recombination of the various genotypes. It is necessary to analyze the genotype distribution and the recombination pattern of alleles as well as alleles and genotype frequencies in each populations for statistical test at most highly polymorphic loci.

It has been generally believed that the continuous flow of blood characterised by arterial inflow and venous outflow is essential for the survival of flaps. Since Baek et al.(1985) demonstrated the survival of a flap based on only a single vein without arterial inflow, there have been a lot of reports of successful skin flaps that depend on only venous blood flow. The location of pedicle is one of the important factors on the survival of flaps, but there have not been an effective study on the survival rates of venous island flaps according to their location of pedicles. In this study, we compared the survival rates of proximally based venous island flaps with those of distally based ones and attempted to decrease the difference, if any, in the survival rates between them. Distally or proximally based 4x3 cmvenous island flap, whose pedicle was a marginal branch of central vein, was elevated from the auricular cartilage of New Zealand white rabbit. IN the half of 20 rabbits, superoxide dismutase (SOD, 20,000 U/kg) was injected intravenously 30 minutes and 60 minutes after the flap elevation. On the 7th postoperative day, survival areas of the flaps were measured by image analysis system and the vascular network with the flaps were examined by micro fil cast. 40 flaps were divided as follows: proximally based venous flaps, distally based venous flaps, SOD treated proximally based venous flaps, SOD ttreated distally based venous flaps. The results were as follow: 1. The survival rate(79.39+/-9.24%) of the proximally based venous flaps were significantly higher than those(60.79+/-14.10%) of the distally based ones (p< 0.01). 2. SOD improved survival of the flap significantly (p< 0.05), and there was no statistical difference in the survival rates between proximally based venous flaps and SOD treated distally based venous flaps (p = 0.1785). 3. Revascularization was actively developed in the proximally based venous flaps and those flaps treated with SOD, but was minimal in the distally based venous flaps. These results suggested that the vascular pedicle would rather be located proximally than distally in designing the venous island flaps and that SOD treatment may be effective for the enhancement of survival of venous island flaps, especially in distally based ones.

Many investigators were interested in the pathogenesis and the relationship between microscopical features and clinical behavior of hydatidiform mole. Trophoblastic cells in the trophoblastic disease were intensively examined histologically, ultrastructurally, immunohistochemically, and with hormone assay method, etc. But ultrastructural study on the stroma of hydatidiform mole was scarcely reported. In this paper, hydatidiform mole was examined at light and electron microscopic levels, with emphasis on the stroma. The results were as follows: 1) Hydropic degeneration of H-mole is more severe in the center of stroma and is not related with the degree of trophoblastic proliferation. Hofbauer cell and vascular structure are extremely rarely observed in the periphery of stroma which has relatively preserved cellular components. 2) Basement membrane is sometimes separated from trophoblastic layer. Degenerated cells in the stroma contain vacuoles, autophagosomes, and lipid droplets. Collagen is abundant in the loose interstitium. Hofbauer cells have no lysosome or phagosome. Vascular lumen is patient and endothelial cells are degenerated. From the above results, H-mole may be produced due to abnormal changes of trophoblasts and stromal changes may be a secondary process, so called autolysis. Hofbauer cells are not engaged in the stromal degeneration and may be different from usual tissue macrophages.

A case of znelanotic whitlow is presented which resembles clinically as chronic paronichia. Patient was 71 years old man and he has had a single brownish pigmented spot on left mid. finger since 3 years ago which was progressively grow and skin biopsy could be established the pathological diagnosis of superficial malignant melanoma.

Weber-Christian disease is a relapsing, febrile, nodular, nonsuppurative inflammation of the subcutaneous fat tissue. Many authors reported these cases which illustrate the great variability of the clinical manifestation, such as acute or chronic, fulminating or transient, febrile or non febrile, systemic or cutaneous. Two of our cases have had recurrent painful subeutaneous nodules without fever for several years. Biopsy showed a nonspecific inflammatory panniculitis with lymphocytes chiefly, and small amount of histiocytes and foamy cells. It should be suggested Weber-Christian disease when subcutaneous nodules appear recurrently same areas of the whole body surface except anterior aspects of tibia even if no fever as systemic manifestation. Treatment with steroid and chloroquine diphosphete produced good improvement.
