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.

The concurrence of typical carcinoid admixed with adenocarcinoma of the gastrointestinal tract is a well known but unusual phenomenom that has been reported in the esophagus, stomach, gall bladder, colon and appendix. The amine precursor uptake and decarboxylation (APUD) concept included the idea that neuroendocrine cells of the gastrointestinal tract were dervied from the neural crest by a process of migration during embryogenesis. However the intimate admixture of cells which have morphologic and immunocytochemical properties of both carcinoid tumors and adenocarcinoma suggests that these tumors are derived from a multipotential stem cell showing bidirectional differentiation rather than from unrelated cell lines. The term composite carcinoma-carcinoid tumor is therefore an appropriate designation for these neoplasms. We report a case of composite carcinoma-carcinoid tumor of the stomach in a 38 year-old female with brief review of literature.

The accessory ovary can be defined as an extraovarian tissue that is located near the normal ovaries and is connected to the broad ligament, infundibulopelvic ligament or utero-ovarian ligament. It has very rarely been reported. The majority was found during abdominopelvic surgeries for any other purposes, because they were usually small and less than 1 cm in diameter adn gave no particular symptoms related simply to their presence. We reported a case of accessory ovary in which developed a simple cyst of a largest diameter of 12 cm, and discussed the significance of the accessory ovary in clinical and pathological aspects.

BACKGROUND: Gamma linoleic acid (GLA, Epogam) is considered a safe and effective modality in the treatment of atopic dermatitis (AD) in which impaired function of the enzyme, delta-6-desaturase, has been reported to result in reduced levels of GLA, desaturated fatty acids. OBJECTIVE: We performed this study to observe the changes of skin surface conditions measured objectively by bioengineering methods in relation to clinical improvement after treatment with GLA (Epogam®) in children with AD. METHODS: Thirty-four children with AD were treated with GLA (Epogam®) and evaluated with clinical parameters.The changes of skin surface conditions were monitored by non-invasive experimental instruments. RESULTS: There was a significant decrease of transepidermal water loss (TEWL) and gradual improvements in clinical severity after 12 weeks of GLA (Epogam®) treatment. The change of skin surface pH was statistically significant on the antecubital fossa and abdomen except the popliteal fossa. The other parameters including skin surface hydration and skin surface lipid did not show consistent changes. CONCLUSION: Clinical improvement of AD with GLA (Epogam) seemed to be achieved by the reduction of TEWL.

The surgical intervention of renal staghorn calculi was performed in 9 patients(lOkidneys) who had undergone anatrophic nephrolithotomy with in situ hypothermia. admitted to the Department of Urology, HaniI Hospital, during four years periods from June, 1982 to May, 1986. This operation technique is simple, easy but uneventful recoveries followed only in a small group. The results were summarized as followings : l. Postoperative hospitalizations were 13.1 days(ranged from 8 to 21). 2. Operating time required 194.5 minutes with mean time(ranged from 150 to 230). 3. Renal artery clamping time required 36.4 minutes with mean time(ranged from 23 to 65). 4. Blood loss during operation was 875ml on the average loss(ranged from 350 to l400). 5. Postoperative complications were nephrectomy l case, pneumothorax l case, deep vein thrombosis l cases remained stone 3 cases.
