A clinical observation of self-inflicted lesions was made during physical examination for conscription in Choongcheongnamdo from May to July, 1980. The result were as follows: 1) The prevalence of self-inflicted lesions was 8. 1% (579/7148). 2) The number of persons with criminal history was 68(ll.7%). 3) The educational level of self-injured was lower than that of non self-injured. 4) Most frequently used tools for self-inflicted lesions were cigarette(72%), knife(19. 9%), rnatch(14.7%) and grass(12.8%) in decreasing order of frequency and only one tool was used in 438 cases(75.6%). 5) The favorite site of self injury were the left forearm(89. 5%), right forearm (19.3%) and left upper arm (5.9%) 6) The average age of first injury was 16. 5 years. 7) The complications of self injury were found in 8. 8% of self-injured and they were hypertrophic scar, keloid, pyoderma and depigmentation. Some degree of hyperpigrnentation and hypopigmentation was found in most of cases. Tattoo was accompanied in 20. 7% of self-injured.

Primary cystic neoplasia of the liver is rare. We report a cystadenoma with mesenchymal stroma (CMS) and a cystadenocarcinoma, and make a review of literature with particular reference to their histogenesis. The CMS has many similarities to the ovarian mucinous cystadenoma; occurring almost exlusively in female, being lined by mucus-secreting epithelial cells, and containing dense ovarian-like stroma. These features suggest that CMS may arise from the ectopic ovarian tissue within the liver. Cystadenocarcinoma may have its origin in CMS or cystadenoma without mesenchymal stroma of CMS. Cholangiocarcinoma arising from the congenital hepatic cysts can be differentiated only when it contains benign epithelia.

BACKGROUND: Clinical features of atopic dermatitis(AD) have been well described according to age in the English literature. In Korea there have been some reports about clinical analyses of AD. However, there is no report about the clinical characteristics of adult AD. OBJECTIVE: We tried to characterize the clinical features of adult AD by comparing them with the childhood/infantile type. In addition we aimed to study the prognostic factors that may be related to the persistence of dermatitis into adult life. METHODS: Patients with AD were divided into the adult and childhood/infantile types according to the patient's age. Sixty three adult patients were compared with 107 childhood/infantile patients. Various clinical characteristics of AD were compared between these groups. RESULTS: Orbital darkening, foot eczema, and extensor involvement were more frequently observed in the childhood/infantile type, whereas flexural lichenification, especially in the antecubital fossa, prurigo papules in the extensor part of the extremities, cheilitis, forehead lichenification, Hertoghe's sign, nipple eczema, and anterior neck fold involvement were more frequent in the adult type. Light sensitivity was more prominent in the adult type. Later age at onset of AD was observed in adult patients. The incidence of respiratory atopy (asthma and allergic rhinitis) was higher in the adult group. CONCLUSION: In the adult type flexural involvement with lichenification became more prominent and prurigo papules were more frequently observed in the extensor part of the extremities. Later onset of AD and association with respiratory atopy were considered to be bad prognostic factors.

BACKGOUND: Because heterogeneity of the human tyrosinase gene has been reported, it is of vital significance to know the correct nucleotide sequence of tyrosinase in Koreans in order to study the molecular basis of oculocutaneous albinism. OBJECTIVE: This study was done to analyze the nucleotide sequence of tyrosinase gene in Koreans. METHODS: All exons were amplified from genomic DNAs and sequenced directly from three healthy Koreans. RESULTS: The nucleotide sequence of the tyrosinase gene in Koreans encode 511 amino acids with a molecular weight of 58,000. CONCLUSION: The nucleotide sequence of coding region is the same with that of pHTrl(Shibahara et al. Tohoku J Exp Med 156: 403-414, 1988). As we couldn't observe any polymorphisms in Koreans these results suggested the homogeneity of Korean people.

BACKGROUND: Recently the sensitive measurement of radiation damage to DNA using flowcytometric analysis of nucleoid preparations was reported which allows an analysis of damage within the DNA of single cells. We applied flowcytometric analysis of the nucleoids for the detection of DNA damage by UVB. OBJECTIVE: The purpose of this study was to establish the method of detecting UVB-induced damage of DNA by flowcytometry and to elucidate the usefulness of this method to detect cell damage. METHODS: Human melanoma cells were cultured and were irradiated with various of UVB. Immediately after UVB irradiation nucleoid suspensions were prepared and flowcytometric analysis was done. RESULTS: The changes in fluorescence, forward scatter, and side scatter reflected damage of DNA induced by UVB quite well especially at lower UVB doses. CONCLUSION: Flowcytometric analysis of nucleoid will be a useful methosd to detect DNA damage by UVB.

Although wound healing is a natural biologic process by which the homeostasis is preserved, the resultant hypertrophic scar or scar contracture may produce undesirable morphologic and functional sequelae. To overcome these problems, a number of attempts to produce skin substitute have been made in recent years, but none have proved to be entirely satisfactory. We compared the wound healing of full-thickness dorsal skin defects between ADM(acelluar dermal matrix)-applied wound and ADM non-applied wound group in 20 adult female Sprague-Dawley rats. The wound area was serially evaluated at 1,2,3 weeks and the difference in the mean area ratios between the two groups was then statistically analyzed using Wilcoxon rank sums test. We also performed histological evaluation of the wounds at 1,2,3 weeks. Results were as follows: 1. Experimentally produced ADM was easy to handle. Histologic findings showed no epithelium, no appendages, no cells dermal and subcutaneous layer and pure bundles of collagen. 2. The wound area ratio of ADM applied wound group was statistically larger than that of ADM non-applied(control) wound group. That is, ADM was able to inhibit the wound contraction compared with the ADM non-applied wound group. 3. In the ADM-applied group, we observed low grade exudates, no infection, fine take-up of ADM on full-thickness skin defect, gross and histologic findings of neovascularization, and progressive epithelization on ADM. These findings of biologic attachment implies the function of the ADM as a dermal substitute. These can be basis of the study on the development of artificial skin.

Nickel is widely known as a common source of contact dermatitis and nickel sensitivity amounts to nearly 10 percent of allergic contact dermatitis patients. Common sources of nickel dermatitis are well known as necklaces, watches, rings, hooks, earrings and spectacle frames. Recently, we have seen five cases of nickel dermatitis the suspected sources of which were metal spectacle frames. The interim patch test result in our occupational and environmental clinic suggests that the metal spectacle frame is one of the most common sources of nickel dermatitis. Out of 84 medical students 27 wore metal spectacle frames. We have done a dimethylglyoxime spot test to the metal spectacle frames and got a positive result in 12 out of 27(44.4%). We conclude that metal spectacle frame seems to be one of the dominant causes of nickel dermatitis and it will be an increasing problem in our society.

BACKGROUND: Recently doubts have been raised regarding the diagnostic significance of some of the minor clinical features of atopic dermatitis (AD) proposed by Hanifin and Rajka. Some of them may be nonspecific and racial difference was suggested. OBJECTIVE: The purpose of this study is to evaluate the diagnostic significance of 14 minor clinical features out of Hanifin and Rajka's 23 minor features of AD in the Korean pediatric population. The significance of 5 more items was evaluated as additional minor features. METHODS: The difference in frequency of the total 19 features of AD was compared between 100 patients with AD and 76 controls. RESULTS: Fourteen of these were shown to be significantly more frequent in patients than in controls including our 5 additional clues such as scalp scaling, postauricular fissure, infraauricular fissure, forehead lichenification, and infragluteal eczema. CONCLUSION: Our study about the minor features may be a valuable guideline for the diagnosis of AD in the Korean pediatric population.
