OBJECTIVE: In the previous study, we compiled the differentially expressed genes during early folliculogenesis.1 Objective of the present study was to identify downstream target genes of transcription factors (TFs) using bioinformatics for selecting the target TFs among the gene lists for further functional analysis. MATERIALS AND METHODS: By using bioinformatics tools, constituent domains were identified from database searches using Gene Ontology, MGI, and Entrez Gene. Downstream target proteins/genes of each TF were identified from database searches using TF database (TRANSFAC(R) 6.0) and eukaryotic promoter database (EPD). RESULTS: DNA binding and trans-activation domains of all TFs listed previously were identified, and the list of downstream target proteins/genes was obtained from searche of TF database and promoter database. Based on the known function of identified downstream genes and the domains, 3 (HNF4, PPARg, and TBX2) out of 26 TFs were selected for further functional analysis. The genes of wee1-like protein kinase and p21WAF1 (cdk inhibitor) were identified as potential downstream target genes of HNF4 and TBX2, respectively. PPARg, through protein-protein interaction with other protein partners, acts as a transcription regulator of genes of EGFR, p21WAF1, cycD1, p53, and VEGF. Among the selected 3 TFs, further study is in progress for HNF4 and TBX2, since wee1-like protein kinase and cdk inhibitor may involved in regulating maturation promoting factor (MPF) activity during early folliculogenesis. CONCLUSIONS: Approach used in the present study, in silico analysis of downstream target genes, was useful for analyzing list of TFs obtained from high-throughput cDNA microarray study. To verify its binding and functions of the selected TFs in early folliculogenesis, EMSA and further relevant characterizations are under investigation.

The subjects of the present study were 111 patients admitted to a hospital and 304 healthy people living in similar condition. A self report symptom inventory, SCL-90(symptom check list-90) was used and the two groups were analysed and compared by many factors. The results of theis study are as follows. 1. All dimensional values of the psoriasis group were much higher than the normal healthy group. In order of significance: depression, anxiety, obsessive-compulsive, psychotism, interpersonal sensitivity, hostility, and somatization(all p<0.01). This result indicates a significantly heightened incidence of psychological problems among psoriatic patients. 2. There were significant differences between each clinical type. As a whole, common and pustular types showed highter dimensional scores than guttate type. 3. In the psoriasis group, subjects over 30 years old had higher scores except in somatization and paranoid ideation dimensions. However there was no significant relationship between age and dimensional scores. 4. Female psoriatic patients showed higher values than male patients on all dimensions excopt paranoid ideation. T verification showed significance in depression and hostility (p<0.05). 5. Analysed by marital status, generally unmarried patients had higher dimensional scores than married patients, but there was no significant differences. 6. In contrast with the control group, psoriatic patients of low educational status showed higher dimensional scores than patients of high educational status. 7. Analysed by job at onset of disease, student patients showed the lowest scores. There were significant differences for somatization(p<0.01) and paranoid (p<0.05) dimensional scores. 8. Analysed by the age of onset of disease, the patients who developed psoriasis before 20 years of ages showed higher dimensional scores than the patients, after 20 years of age. 9. Compared according to duration of the disease, dimensional scores rose in patients under 1 year duration decreased in patients of 1 to 2 years' duration and rose again in parients over 3 years' duratio. 10. As the accuracy of understanding about the disease decreased, the dimensional scores tended to be higher.

From September 1983 to August 1984, the clinical observations regarding cutaneous manifestations of 26(j cases of in-patients in the Department of Internal medicine with hepatic problems were observed at the Department of Derrnatology in Chonnam University Eiospital, The results were as follows: In the 266 patients, 201 patients(75.6%) revealed various cutaneous manifestaiions; Among them vascular spider occured in 100 (37. 6%), bleeding tendency in 67(25. 2%), pruritus in 65(24.4%), jaundice in 59 (22.2%), palmar erythema in 59(22. 2%), and melanosis in 56(21. l%). The incidences of skin changes by pattern of liver disease were as follows; In acte hepatits, prurit;us(46.8%) and acute urticarial & maculapapular eruption(36. 4%) were found in order. In chronic hepatitis, vascular spider(42. 6%) and melanosis (27. 9%) in order. In cirrhosis, vascular spider (62. 5%) and bleeding tendency (42. 0%) in order. In hepatic cancer vascular spider (24. 2%) and jaundice (21. 2%) in order. There were no statistically significant differences in sex distribution. In the incidences of skin changes by age groups, jaundice(p<0. 01) and melanosis were more frequently observed in the patients under the age of 29 and vascular spider (p<0.01 ) and melanosis in the patients are the age of 50. The longer the duration of illness were, the higher the incidences of skin changes except jaundice were.

Cutaneous horn is a clinical term for a circumscribed concial hyperkeratotic mass amounts to at least half of its largest diameter. The number of lesion may be single or multiple. We report herein a cases of penile cutaneous horn in a 22-year-old male. He had dark brownish colored conical shaped protruded mass on the penile shaft for about 2 months. We performed excisional biopsy and curettage. Histopathologic findings showed verruca vulgaris.

From March 1987 to July 1989, six patients (five dadults and one child) with lung abscess (size, 5-13cm in diameter) were treated with percutaneous aspiration and drainage. In each case, the puncture was made where the wall of the abscess was in contact with the pleural surface. An 8 to 10 Fr catheter was inserted for drainage. Five of 6 had a dramatic clinical response within 24 hours of the drainage. Percutaneous drainage was successful with complete abscess resolution in four and partial resolution in one patient. No response was seen in the rest one. The duration of drainage ranged from 7 to 18 days (average, 15.5days) in successful cases. One case of the failure in drainage was due to persistent aspiration of the neurologically impaired patient. In one patient, the abscess resolved after drainage but recurred after inadvertent removal of the catheter 7 days after insertion. In two patients, concurrent pleural empyema was resolved completely by the drainage. Computed tomography provided anatomic details necessary for choosing the puncture site and avoiding a puncture of the lung parenchyma. Percutaneous catheter drainage is a safe and effective method for treating patients with lung abscess.

Cribriform-morular variant of papillary thyroid carcinoma is an unusual and peculiar subtype of papillary thyroid carcinomas. It occurs both sporadically and in association with familial adenomatous polyposis. We report here on two cases of cribriform-morular variant of papillary thyroid carcinoma in a 33-year-old woman and in a 21-year-old woman. On gross examination, both cases were multicentric. The first case showed two well-encapsulated yellow solid masses in the right (2.0 cm) and the left lobes of the thyroid gland (0.5 cm). The second case showed four well-encapsulated gray-white solid lobulating masses and nodules in the right (4.5 and 1.2 cm) and the left lobes (1.1 and 0.8 cm) of the thyroid gland. Microscopically, both cases exhibited an intricate blending of papillary, cribriform, trabecular, spindle, and solid patterns of growth with morular areas. Typical nuclear features of papillary carcinomas were focally seen. Immunohistochemically, the tumor cells were positive for thyroglobulin, thyroid transcription factor-1 (TTF-1), and beta-catenin, but were negative for calcitonin.

Contact urticaria refers to a wheal-and-flare response occurring on the application of chemicals to intact skin. When contact urticaria is accompanied by systemic symptoms, it is known as the urticaria syndrome. Fourteen cases of cefotiam-induced contact urticaria have been reported in the foreign literature, but no such case, as far as we know, has been described in the Korean dermatology literature. We report a case of contact urticaria syndrome occurring in a 23-year-old nurse due to occupational contact exposure to cefotiam. She experienced generalized urticaria, itching of the skin, difficulty in breathing, and abdominal pain, when she was preparing an injection of cefotiam. An open patch test showed positive reactions to cefotiam, cefmetazole, and ceftriaxone. Since avoiding cefotiam, the symptoms disappeared and did not recurred.

Emphysematous cystitis is a rare condition characterized by gas collection in the wall and lumen of the bladder. We experienced three cases of emphysematous cystiris. All patients were female; one was associated with a long term history of diabetes mellitus and another with urinary indwelling catheter. All of the cases were easily diagnosed on plain radiograph and CT scan, and were successfully treated with antibiotic therapy. In one of the cases, however, associated abscess due to perivesical extension of inflammation was treated by combined external drainage.
