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.

2.The comparison of survival of the venous flaps according to the location of pedicle and the treatment of superoxide dismutase in the rabbit auricle.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 1998;25(4):538-546
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.

The nodular vasculitis described by Montgomery on 1945 and is characterized by relatively chronic, persistent, or recurrent nodular lesions of nontuberculous origin chiefly on the legs. In the differential diagnosis the following must also be considered; erythema induratum, eythema nodosum, Weber-Christian disease, erythema nodosum migrans, recurrent thrombophrebitis and periarteritis nodosa. The authors observed one case of nodular vasculitis caused by sulfa drug. This patient was diagnosed to papulonecrotic tuberculid at first and treated by prednisolone 20 mg, INH 300 mg and streptomycin l.0 gm BIW. By the treatment, the patient, was cured completly within 3 months but visited again because of recurrence after 6 months. Therefore, same medication was given, but did not show improvment and added sulfa drug, Lederkyne. But, unfortunately the skin lesions was aggrevated after sulfa medication. It was suggestive that the cause of aggrevation was sulfa drug and discontinued the sulfa drug. The skin lesions were completely cured after the drug was discontinued.

Korean Journal of Pathology 1987;21(4):240-248
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.

Mucoepidermoid earcinoma occurred in about 2% among salivary gland tumor and in about 15% among malignant parotid gland tumor. The tumor occurred usually in elderly persons and arose as innocent-appearing swelling in the parotid gland region with gradual painless enlargement without alarming and it's usual size is less than 2 cm, However, a few of the poorly differentiated neoplasms grew rapidly and were painful and accompanied by facial nerve paralysis in about 15%. But it's prognosis is better than other salivary gland origin. We report a case of typical mucoepidermoid carcinoma of parotid gland origin which is occurred in 15 years old girl. The tumor begins pea sized painless nodule since about 2 years ago, and enlarged gradually to apple size and accompanied by facial nerve paralysis and pain sensation recently. But there was no evidence of tumor in parotid gland itself and no metastasis.

Korean Journal of Dermatology 1974;12(4):219-228
Dermatologic treatment was greatly advanced when topical corticasteroids were introduced for the management of many inflammatory and pruritic dermatoses. Their use reduced or diminished mnst of the undiserable side effects which accompanied the systemic administration of these compounds. The good effects of topical application of hydrocortisone had been demonstration in the treatment of variaus dermatoses eg., atopic dermatitis, seborrheic dermatitis, contact dermatitis etc. The halogenated derivatives followed and led to the trend to most of analogs now in use. Especially, fluocinolone acetonide cream greatly enhanced its therapeutic effectiveness in psoriasis, chronic discoid lupus erythematosus, pustular bacterid, granuloma and neurodermatitis circumscripta. But many side effects of topical corticosteroids such as steroid acne. Stria were developed and also fluorinated topical corticosteroids resulted in telangiectasia, purpura, atrophy in skin. Weber reported that strong topical corticosteroids eg.. Betamethasone valerate and fluocinolone acetonide were resulted in rosacealikc dermatitis and it was steadily increased. These adverse side effcts of topical corticosteroids, especially steroid acne, were indisputable argument in dermatologic field, for the view that this topical corticosterodis is used for cosmetics and treatment of acne vulgaris in our country. Since the strong corticosteroid tnpical preparation, the peculiar form acne, so called steroid acne, was steadily increased in our clinic. Behrman and goodman reported that acneform eruption induced by hormone was not associated with oiliness and there were but few comedone. Sullivan and Zeligman reported that the the acneform eruption due to adrenal corticaa 1 hormone was uniform in size, small papule and few pustule, usualIy erythematous base. There were also differential histologic feature. The most important difference is the normal apperance of sebaceous glands in acneform eruption due to corticosteroids contrast with hyperplasia in acne vulgaris. Abscess formation was more frequent and more extensive in acne vulgaris. Sutton Jr and Van Scott & MacCardle described that histologically, the major component in lesion of steroid acne was excessive keratinization of follicle. Castor and Baker demonstrated that topical application of corticosteroids resulted in decrease of sebaceous gIands, decrease of mitosis and increased cornification in epidermis. The present study investigated clinical case of the steroid acne, which are induced by topical application and systemic administration of corticosteroids and experimentally induced the steroid acne with the topical application of corticosteroid. And also clinical cases and experimentally induced steroid acne were compared with acne vulgaris. Material and method Subjects are 13 Patients of steroid acne induced by strong topical corticosteroid eg., fluocinolone acetonide, fluocortolone, dexamethaone, betamethasone valerate and 4 patients of steroid acne induced by systemic administration of corticosteroid eg., prednisolone and also 10 patients of acne vulgaris. Biopsy was performed from 13 patients of topical steroid acne, 3 patients of steroid acne induced by systemic administration of steroid and one patient of acne vulgaris. In order to induce steroid acne, experimentally, strong topical corticosteroid such as beta methasone valerate, fluocinolone acetonide and fluocortolone were applied on back. Comment and conclusion In Clinical feature, the steroid acne by topical application and systemic administration of corticosteroid and experimentally induced steroid acne had unique clinicall features, that showed absence of comedone and uniform sized follicular papule on deep seated erythematous scaly base. The topical steroid acne was distributed the region where were applied. But the eruption of the steroid acne induced by systemic administration of corticosteroids was distributed to face, neck, and scalp. Above findings are quite different form acne vulgaris. Histopathologically, the steroid acne induced by topical application and systemic administration of corticosterojds showed hypoplasia of sebaceous glands and excessive follicular keratinization. Occlusion of pilosebaceous opening by keratotic plug in severe case by long term application showed atrophy of epidermis and sparsity of sebaceous glands with hypokeratosis and parakeratosis. In experimentally induced steroid acne, it was definitely specific features which were absolutely identcall with above cinical steroid acne.

Korean Journal of Dermatology 1974;12(3):199-202
Erythroplasia of Queyrat is a precancerous lesion, usually located to glans penis or prepuce. It is characterized by a slowly developing, circumscribed, usually velvety and shiny patch. The etiology was unknown, but it is extremely rare in those circumcised in early infancy. It had been suggested that phimosis had some etiologic importance. The typical case of Erythroplasia of Queyrat is presented. A 46 year old man had 4 months history of dark-brownish pea sized maculopapular rashes on sulcus of glans penis and prepuce associated with mild itching, which was increased in number day by day. He had a phimosis. On examination, there are sharply defined, slightly elevated, pea sized dark-brownish maculopapular rashes over erythematous infiltrated base on sulcus of glans penis and prepuce, which have moist and velvety appearance. A biopsy was performed from sulcus of glans penis. Histopathologically, there was acanthosis, with in epidermis many cells are vacuolated and showed individual cell keratiinization. Epithelial cell showed marked atypia, variation in nuclear size and there was intercellular, intracellular edema. The lesion was treaterd with topical application of 5% 5-fluorouracil twice daily 2 weeks and thereafter for 4 weeks. 2 months after treatment, no erythroplastic lesion was found and 3 months after treatment, rebiopsy was perforrned which showed marked improvement histopathologically.

This clinical study of nine patients presented Disseminated Superficial Actinic Porokeratosis (DSAP) as a distinctive and recognizable entity characterized by multiple uniformly small, irregular marginated, keratotic plug with atrophic center developing during second or third decade of life on sun exposed area of skin. Six of nine patients had DSAP, which was inherited as autosomal dominant trait. The patient's father, two brothers and two sisters were known to have same skin lesions. Of nine patients, five were female and four were male. Eight patients were developed DSAP lesions during second decade of life and other one was third dcade of life. Three patients had pruritus. In alI patients, lesions were developed bilaterally over sun exposed area but was not always symmetrical. The number of lesion was multiple in all patients. The greatest number of lesions were found on distal part of extremities, neck, face, upper portion of anterior chest and back.

The case of a 30 year old man is described, in whom mycosis Fungoides was originating from nose and followed by tumor stage of Mycosis Fungoides on skin. In January 1970, the patient leveloped nasal tumor, when he was n at E.N.T. department of Severance Hospital. At that time a biopsy of nasal tumor demonstrated only a non-specific inflammatory cell infiltrated mass. He received radiation therapy (Co 60) with satisfadory suppression of mass and resulted in right nasal septal deviation. Jn December 1970, thumb sized painful non-tender, movable mass developed on right supraclaviular area. In August 1971, thumb sized painful, tender, movable mass appeared at right posterolateral aspect of neck, which was excied and removed at local clinic. But excised wound was not healed and the mass was enlarged. One month after above lesion, pea sized same mass developed. On physical examination, there were 4*5cm round, erythematous, painful, tender, granulomatous ulceration mass on right postero-lateral aspect of neck and also same mass on postero-inferior site of above lesion. Two times of biopsy was done and it interpreted as tumor stage of Mycosis Fungoids. Treatment included radiation therapy with Co 60 (200r/day, total 6,000r), prednisolone 40mg/day and antibiotics. There has been good response 1 month after radiation therapy and mass is diminished in size and would begin to heal.

Recently, the number of cataract surgeries has rapidly increased. This study was devised to evaluate the post-operative daily life behavior and degree of satisfaction in the patients who underwent cataract surgery two or more years ago. Of 400 patients who underwent ECCE with IOL implantation, 125 patients[31%]replied to the mail questionnaire consisted of thirty questions. Hospital records were also reviewed. 84%of the patients were satisfied with outcomes of cataract surgery, which was significantly correlated with current visual acuity[p<0.01]. Degree of satisfaction was significantly higher in patients with bilateral surgery compared with those with unilateral surgery[p<0.05]. Age, sex, occupation, economic and general health status were not significantly associated with degree of satisfaction. As for life behavior, discomfort while driving an automobile was the most common complaint, especially in the patients who underwent unilateral surgery. Concerning ocular symptoms, many patients complained of foreign body sense, epiphora, glare, fatigue, and near vision discomfort. We reconfirmed that the decision to perform cataract surgery should be made with careful consideration of long term prognosis and above results.
