2.Flow Cytometric DNA Content Analysis in uterine Cervical Cancer.
Korean Journal of Gynecologic Oncology and Colposcopy 1994;5(3):49-53
The DNA ploidy using fresh tissues from 304 cervial cancer were analyzed by flow cytometry in order to evaluate the correlation between DNA ploidy patterns and prognostic factors of uterine cervical cancer. There were l67 diploid cases(55%) and 137 aneuploid(45%). No significant correlation was noted in stage, age and lymph node metastases between diploid and aneuploid tumor. But S-phase fraction and DNA index were higher slightly in cases of lymph node metastases cornpaired to non-metastases. This results suggest that the DNA ploidy cannot be used as an independent prognostic fac- tor, but further evaluation will be needed in order to conclude definite relationship between prognoseic factor and S-phase fraction or DNA index.

Characterizations of the VP4 (P type) and VP7 (G type) genes of Korean isolates of bovine rotavirus were performed using RT-PCR/RFLP and nucleotide sequencing analysis. After RT-PCR amplification of partial length (1094bp) of the VP4 and full length (1062bp) of the VP7 genes, amplified PCR products were digested with restriction endonucleases and digestion patterns were compared with those of reference rotaviruses. With the VP4 genes, four RFLP (AD) profiles were observed; three (A, B and C) were the same as those of bovine rotavirus NCDV (P[1]), IND (P[5]) and B223 (P[11]), respectively, Profile D was the same as that of porcine rotavirus OSU (p[7]). With the VP7 genes, five RFLP profiles (I-V) were observed; three of them (1, II and III) were the same as those of bovine rotavirus NCDV (G6), Cody I-801 (G8), and B223 (G10), respectively, Profile IV and V were atypical to those of reference bovine rotaviruses used in this study. These two profiles were identified as G6 and G5, respectively, after analyzing and comparing the nucleotide sequences. The G typing analysis revealed that 61.9% (26/42) were G6, which included G6 subtype; 28.6% (12/42) were G5; 7.1% (3/42) were G10; 2.4% (1/42) were G8. The P typing analysis revealed that 54.8% (23/42) were P(5); 28.6% (12/42) were P(7); 11.8% (5/42) were P(11); 4.8% (2/42) were P(1). Our results showed that G6/P(5) were the most prevalent rotaviruses in diarrheic calves in Korea. Also, this is the first report that G5P(7) rotaviruses were identified from cattle with diarrhea.

PURPOSE: To evaluate the indication for intracavitary Urokinase(UK) in the treatment of Ioculated pleural effusion. MATERIALS AND METHODS: We analyzed CT and US in 31 patients who were treated with intracavitary UK in Ioculated pleural effusion. In each patient, a single chest catheter (10-12F) was insected under imaging guidance. When the amount of drainage was less than 100ml/day, UK was instilled through the catheter until less than 50ml/day was drained. On follow-up chest radiographs of more than 1 month, we classified the results of treatment into 3 groups:(1) completely effective (lung expansion, over 80%);(2) partially effective (20-80%); (3) ineffective (below 20%) group. Sonographic pattern of pleural fluid was classified into anechoic, septated, and honeycomb appearances and the thickness of parietal pleura was measured on CT. RESULTS: Sixteen patients were completely effective, nine were partially effective, and six were ineffective. patients with completely or partially effective outcome had anechoic and linear septated appearance on had less than 4mm of parietal pleural thickness on CT. Of six ineffective patients, US showed linear septated in one patient and honeycomb appearance in five patients and the thickness of parietal pleura on CT was 3 mm in one patient, 4ram in two patients, 5mm in one patient, and 6mm in two patients. CONCLUSION: UK instillation through percutaneous catheter was an effective method in the treatment of Ioculated pleural effusion. However, we found near complete reaccumulation of pleural fluid when honeycomb appearance of pleural fluid on US or more than 5mm parietal pleural thickness on CT was observed, which might suggest that we should consider the other kinds of treatment method in those patients.

A case of a clinical syndrome of selective hereditary complete IgA deficiency with partial T-lymphocyte inactivation is reported. A 14 year old boy was admitted with chjef complaint of persistent wide shallow ulcerated non-vesicular patches on the skin folds of whole body, chronic upper respiatory infections and gastointestinal upsets. General appearance showed us as if the undemourished or malabsorption status had been accompanied. The duration of illness was about 10 years under the incorrect or mistaken diagnosis and skin lesions have incompletely responded to the treatment. Peripheral T-lymphocyte determination was carried out by the method of Wybran to be tumed out active T-cell 14%, total T-cell 48%. Tuberculin test showed negative with 5 TU. Immunoglobulin values were respectively as follows: IgG 325 mg%, IgM 60 mg%, and IgA trace. And we diagnosed this case as selective IgA defiency with partial T-lymphocyte inactivation. We started the immunochemotherapy with tuberculo-protein complex, Tubercin-3 and antibictics for 2 months. After 2 months with above regimen. the skin lesions were markedly improved. T-cell count also retumed to the normal limit(active 35%, total 59%) and levels of TgG and IgM raised(IgG 617.5 mg%, IgM 75mg%), but IgA still showed trace amount, Tuberculin test tumed out positive.

BACKGROUND AND OBJECTIVES: N-cadherin is known to be expressed in neuroectodermal tissue such as central nervous system and various mesodermal origin tissues such as kidney and heart. We investigated N-cadherin expression in the endocardial cushion in developing rat heart by immunohistochemical method. MATERIALS AND METHOD: Fetal rat hearts at the 11th, 13th, 15th, 17th, and 19th day of gestation and the 1st day neonatal rat heart were used. Hematoxylin and eosin stain was performed for normal cardiogenesis, and immunohistochemistry was performed for the expression of N-cadherin in interventricular septum(IVS) during cardiogenesis in rat. RESULTS: Ventricular wall and membranous part of the IVS showed positive reaction with anti-N-cadherin at the 11th day of gestation. Membranous part of IVS was begun to show tracely positive reaction at the 15th day of gestation, and thereafter the immunoreactivity was increased with maturation. At the 17th day of gestation mesenchymal cells in membranous muscular part of the IVS showed positive reaction. The similar immunoreactivity of membranous and muscular parts of IVS were shown at the 19th day of gestation. CONCLUSION: As the immunoreaction of mesenchymal cells in the membraneous part of IVS to anti-N-cadherin was increased with time, it is suggested that mesenchymal cells in membranous part of IVS were differentiated into the cardiomyocytes.
