Among 202 aneurysmal patients with SAH who were admitted to Kyungpook National University Hospital from Jan. 1984 through Jan. 1988, the incidence of ventricular dilatation confirmed by postoperative follow-up brain CT scannings was 32.2%(65 cases). And 33 cases(19.3%) was in mild ventricular dilatation, 9 cases(4.5%) was in moderate and 23 cases(11.4%) in severe who needed the shunting procedure were analysed. The incidence of ventricular dilatation to the site of aneurysm was highest in A-com A. aneurysm(42.2%), followed by P-com A. aneurysm(36.4%) and MCA aneurysm(11.3%). The incidence of ventricular dilatation and the need for shunting was higher in multiple bleeding patients than the single. The good risk patients had meaningfully lower incidence of ventricular dilatation than the poor risk group. In the delayed surgical group showed significantly more numbers of ventricular dilatation needing the shunt than the cases in early group.

Analyses and studies have been made on 34 cases of the combined ICH, showing mass effect among 305 male and female ruptured intracranial aneurysmal patients who were admitted to Kyungpook National University Hospital from Mar. 1984, through Feb. 1990. The incidence of the large ICH was 11.1% with 2.1 to 1 ratio of male to female. The highest age incidence of the hematoma was in the 40 to 60 years bracket. The most frequent site of the aneurysm combined with the large ICH was at MCA aneurysm, 38.6%, followed by at A-com artery aneurysm, 4.8%. The most frequent location of the hematoma was in temporal lobe, 88.2%. The rate of combined large ICH was 20.3% in multiple aneurysmal bleeding patients who revealed higher incidence of the hematoma than the single bleeding patients. In amount of the hematoma, 30-40ml bracket ranked top occupying 32.4% of all cases. After surgical treatment, 29.4% patient was improved to the good and fair on discharge. The rate of mortality was 61.8%, which was mainly due to direct effect of hematoma and cerebral infarction caused by vasospasm.

PURPOSE: Multiparametric flow cytometry is a powerful tool for analyzing the phenotypic, cell kinetic and ploidy heterogeneity of tumor cell populations. But there are major problems such as inaccurate results by the contribution of non-neoplastic cell contamination and the substantial spectral overlap of PI (propidium iodide) into PE (phycoery- thrin) fluorescent emissions on a standard flow cytometer. Recent studies suggested that the emission spectral overlap from PI into PE could be sufficiently compensated electrically and the cytokeratin, a marker for epithelial tumor cells, are successfully used in conjunction with DNA specific dye so as to obtain DNA profiles selectively for cytokeratin-positive tumor cells. The aim of this study was to investigate the feasibility that multiparametric analysis in heterogeneous cell populations of cell lines like solid tumors, which were stained triply with PE, fluorescein isothiocyanate FITC, and PI, can be done without any influences by the contaminated normal diploid cell populations and without spectral overlap between fluorochromes on a standard flow cytometer. MATERIALS AND METHODS: MCF-7 cell lines and heterogeneous cell populations mixed with MCF-7 cells and human peripheral blood lymphocytes were fixed with 1% paraformal- dehyde and permeabilized with 100% methanol. Cytokeratin was labeled with PE and some proliferat!on-associated markers were labeled with FITC, which were followed by DNA staining by PI. These triply stained cells were measured on a standard FACScan flow cytometer equipped with 488 nm single laser and those acquired data were analyzed with WinList 3.0 and ModFit LT software programs on personal computor. RESULTS: Coefficient of variation (CV) of GoG1> peak of MCF-7 cells alone was 4.3. GoG1, S, and G2M phase fractions were 44.9%, 45.9%, and 9.2% respectively. FITC, PE and PI fluorochromes could be detected without any interference between them. CVs of GoG1 peak of PBL and MCF-7 cells in those heterogeneous population were 2.3 and 4.2 respectively. The DNA index of MCF-7 cells was 1.7. MCF-7 cells expressed the cyto- keratin, PCNA, p53, c-erbB/2 and c-myc antigen and in contrast, PBL did not express cytokeratin. The cell cycle phase fractions and oncoprotein expressions could be detected separately in diploid PBL and aneuploid MCF-7 cells in the mixed cell population without any influences by each other. CONCLUSION: These results suggested that the cellular antigen expressions of the malignant cells can be analyzed selectively without influences of fluorescent signals from nonneo- plastic cells. The neoplastic tumor subpopulations are clearly identified on the basis of both ploidy status and antigen expressions. The positive cytokeratin expressions indicate that they were derived from the epithelium, providing objective evidence of the tissue of origin and more precise analysis of DNA contents, ploidy, and oncogene expressions selectively with possible correlation between them. Thus, this method offers new possibilities for multiparameter flow cytometric analysis in the heterogeneous solid tumor cell populations.

BACKGROUND: Psoriasis is an immune-mediated, chronic inflammatory disease affecting multiple aspects of patients' lives. Its epidemiology varies regionally; however, nationwide epidemiologic data on psoriasis depicting profile of Korean patients has not been available to date. OBJECTIVE: To understand nationwide epidemiologic characteristics and clinical features of adult patients with psoriasis visited university hospitals in Korea. METHODS: This multicenter, non-interventional, cross-sectional study recruited 1,278 adult patients with psoriasis across 25 centers in Korea in 2013. Various clinical data including PASI, BSA, DLQI, SF-36 and PASE were collected. RESULTS: A total of 1,260 patients completed the study (male:female=1.47:1). The mean age was 47.0 years with a distribution mostly in the 50s (24.9%). Early onset (<40 years) of psoriasis accounted for 53.9% of patients. The mean disease duration was 109.2 months; mean body mass index was 23.9 kg/m²; and 12.7% of patients had a family history of psoriasis. Plaque and guttate types of psoriasis accounted for 85.8% and 8.4%, respectively. Patients with PASI ≥10 accounted for 24.9%; patients with body surface area ≥10 were 45.9%. Patients with DLQI ≥6 accounted for 78.8%. Between PASI <10 and PASI ≥10 groups, significant difference was noted in age at diagnosis, disease duration, blood pressure, waist circumference of female, and treatment experiences with phototherapy, systemic agents, and biologics. CONCLUSION: This was the first nationwide epidemiologic study of patients with psoriasis in Korea and provides an overview of the epidemiologic characteristics and clinical profiles of this patient population.
