We present herein a case of sebaceous hyperplasia in a 55-year-old male, who showed multiple asymptomatic yellowish papules on the forehead and the cheeks. Histopathologic examination of a papule revealed numerous sebaceous lobules grouped around several enlarged sebaceous ducts. Three weeks of oral administration. of isotretinoin 40 mg per day brought marked improvement.

We experienced three cases of non-giant congenital nevus. They showed zosteriform or heart-shaped grouping of pigmented papules which were pierced by hairs. Histopathologic examination disclosed nevus cell infiltration in and around hair follicles and in the upper two thirds of reticular dermis. We would like to report these cases as follicle-centered spotted grouped pigmented nevi.

The 5-HT2A receptor is of great interest for research into schizophrenia and psychopharmacology in light of the observation that schizophrenic patients has 5-HT cortical-subcortical imbalance and atypical antipsychotic clozpine has 5-HT2A antagonists properties. An significant association between schizophrenia and the T102C polymorphism of the gene for 5-HT2A receptor has been reported. In this study, we investigated an association between schizophrenia and the T102C polymorphism of the gene for 5-HT2A receptor in Korean schizophrenic patients. The subjects consisted of 139 schizophrenic patients and 88 normal controls. Genomic DNA was amplified by PCR and digested with MsPI. The uncutt product identified allele 1(nucleotide sequence TCT) ; digested products of 216bp and 156bp identified allele 2(nucleotide sequence TCC). The allele frequencies and the genotypic distribution of 5-HT2A receptor gene were not significantly different between schizophrenic patients and normal controls. Since allele frequencies of the T102C polymorphism may differ between individuals of different ethnic backgrounds, it needs to be conducted in an advanced research.

5.The Usefulness of the UBC(TM)(Urinary Bladder Cancer) Test for Screening of Transitional Cell Carcinoma of the Bladder in Patients with Hematuria.
Korean Journal of Urology 2004;45(1):14-18
PURPOSE: A new quantitative tumor marker, based on the combined measurement of urinary fragments of cytokeratins 8 and 18, namely the urinary bladder cancer antigen(UBC(TM)) test, has been proposed for the detection of bladder transitional cell carcinoma(TCC). We evaluated the diagnostic efficacy of UBC(TM) test in comparison with that of urinary cytology to establish UBC(TM) test for the diagnosis of TCC. MATERIALS AND METHODS: One-hundred ninety-six patients with hematuria were included in this study. Forty patients were diagnosed histologically as TCC by transurethral resection or radical cystectomy(group A), while the others had various benign urinary tract conditions(group B). RESULTS: UBC(TM) levels were significantly different between groups A (1851.39+/-4627microgram/l) and B (19.28+/-107.03microgram/l) (p<0.001). Sensitivity for diagnosis of TCC was 89.7%(36/40) in UBC(TM) test and 45%(18/40) in cytology(p<0.05). Specificity for diagnosis of TCC was 84.6%(132/156) in UBC(TM) test and 100%(156/156) in cytology. UBC(TM) test was significantly more sensitive than cytology in stage Ta(85.7% vs. 0%, p<0.05), T1 tumors(89.4% vs. 31.5%, p<0.05), and in Grades 1(83.3% vs. 25%, p<0.05) and 2(90.4% vs. 52.3%, p<0.05) tumors. UBC(TM) test was more sensitive in higher Grade(83.3% in Grade 1, 90.4% in Grade 2 and 100% in Grade 3). CONCLUSIONS: In comparison with urinary cytology, UBC(TM) test could be a valuable marker for diagnosis of TCC in patients with early stage and low grade TCC. Therefore, UBC(TM) test in association with cytology may be useful as a screening test for TCC of the bladder.

A complex syndrome, later called as Prader-Willi syndrome, was first described in 1956 by Prader et al, and Zellweger and Schneider characterized this syndrome as hypogonadism, hypotonia, hypomentia and boesty. It is not rare in western countries and more than 400 cases have been reported until 1983. But our interest arose because of our recent experience of diffuse noncirrhotic fibrosis of the liver in a 6 year-old boy who had the clinical features of Prader-Willi syndrome. The core of liver showed destruction of most of the hepatic lobules, particularly of the acinar zone 3, and replacement bt diffuse fibrosis. The remaining liver cells underwent fatty change, and the overall changes resembled chronic sclerosing hyaline disease of the alcoholic type. Inflammation was negligible. This particular case suggests that the severe fatty change of liver could result in irreversible damage to the hepatocytes and progressive fibrosis.
10.Flow Cytometric AHG-CDC for HLA Crossmatch: A Pilot Study.
Korean Journal of Blood Transfusion 2010;21(2):122-131
BACKGROUND: For HLA crossmatch in organ transplantation, complement-dependent cytotoxicity (CDC) is a very useful methodology to detect donor-specific HLA antibodies and their complement fixing ability. In this preliminary pilot study, we investigated whether dead cells induced in anti-human globulin (AHG)-augmented CDC (AHG-CDC) reaction could be measured by flow cytometry ('FC AHG-CDC'). METHODS: This FC AHG-CDC measured the percentage of dead cells (% dead cells) after 7-aminoactinomycin D staining using 3 color flow cytometry. A total 45 flow cytometry crossmatch (FCXM) cases of 12 positives and 33 negatives were further tested using this FC AHG-CDC. RESULTS: The % dead cells of FC AHG-CDC was significantly correlated with the mean fluorescent intensity ratio of FCXM (T cells: r=0.613, P=7.45x10(-6); B cells: r=0.404, P=0.006). The positivity rate of FC AHG-CDC among FCXM positive cases was relatively high: 80% (8/10) for T cells and 75% (9/12) for B cells. The negativity rate of FC AHG-CDC among FCXM negative cases was 100% (35/35) for T cells and 91% (30/33) for B cells. CONCLUSION: In this pilot study, FC AHG-CDC could yield quantitative values, % dead cells, which was proportional to the level of complement-fixing cytotoxic antibodies against T and B cells, respectively, even without physical separation of cells or serial dilution of serum.
