One hundred eighty-six cases of ovarian common "epithelial" tumor including 28 endometriosis were reviewed, from the pathology file of the department of pathology of the National Medical Center during a period of 8 years and 6 months from January 1976 to June 1984. The study consisted of 14 cases(77.4%) of benign tumor including 28 cases of ovarian endometriosis, and 21 cases(11.3%) of borderline malignancy and 21 cases(11.3%) of invasive malignant tumors. Among benign common "epithelial" tumors, mucinous cystadenoma(69 cases) was the most frequent tumor, followed by serous cystadenoma (42 cases) and Brenner tumor (5 cases). Of borderline tumor, borderline mucinous tumor (18 cases) was more frequent than serous tumor (3 cases). Serous cystadenocarcinoma(9 cases) was the most frequent malignant tumor, followed by mucinous cystadenocarcinoma(6 cases), endometrioid carcinoma(3 cases) and undifferentiated carcinoma(3 cases). Most ovarian common "epithelial" tumors were prevalent during the reproductive age, but malignant tumors were more prevalent after the age of 40. Although right side was more frequently found (85 vs. 67) there is no significant site predilection. Bilaterality was the most common in undifferentiated carcinoma(66.7%), followed by serous cystadenocarcinoma(44.4%) and Brenner tumor(40%). The size of tumor tended to be larger in malignant tumor than benign. Mucinous tumor were usually larger than serous tumor. There were 7 intrauterine and 1 ectopic tubal prognancy which were associated with ovarian common "epithelial" tumors. Three cases of tumors were excised during Cesarian section. In summary these findings are comparable to other reports in Korea and English literatures. Histologic analysis of borderline and malignant epithelial tumor was done to emphasize their biologic behavor. Further study is required to compare their histological grading and clinical staging with thier survival rate.

BACKGROUND: The clinical significance of mean platelet volume (MPV), platelet distribution width (PDW) and megathrombocyte index (MTI) is not clear. METHODS: We examined platelet indices in 900 cases of patients with hematologic disorders and compared them with those of the control to predict thrombopoiesis in the bone marrow. MPV and PDW were measured by Coulter Counter STKS (U.S.A). We calculated megathrombocyte index (MTI, the percentage of megathrombocytes) in the peripheral blood film using ocular micrometer, and examined megakaryocyte number in the bone marrow aspirates. RESULTS: In patients with acute leukemia, and aplastic anemia, MPV and MTI were lower than the control but PDW was higher. In myeloproliferative disorders, all platelet indices were higher, and in ITP (idiopathic thrombocytopenic purpura), MPV and MTI were higher but PDW was not significantly different. MTI was higher in complete remission than initial acute leukemia. All platelet indices were not significantly different between pre- and post-BMT in AML. But in aplastic anemia, MPV and MTI were higher in post-BMT than pre-BMT. MTI was a better index to screen than MPV in the decreased megakaryocyte group, but in increased megakaryocyte group, there was no difference in screening ability between MPV and MTI. CONCLUSIONS: The platelet indices in peripheral blood may be good markers for predicting thrombopoiesis in hematologic disorders and in post chemotherapy of acute leukemia. In addition, after BMT of aplastic anemia, these indices could be used as valuable markers of engraftment.

Subungual exostosis are not uncommon, however, they are infrequently mentioned in the dermatologic literature. We report herein a rase of subungual exostosis in the great toe of 16-year-old female student which was confirmed by histopathologic and radiologic findings. Histopathologic examination showed that the mass was ooeered by a dense fibrous tissue which merged into a fibrocartilage cap and bone. Computed tomography showed a well defined, oval shaped, radiopacity of bony density capped by a radiolucency.

To investigate the imbalance of the cytokine production profile of T cells from atopic asthmatics, we measured concentrations of IL-4, IL-5 and IFN-y by ELISA method in the culture supernatants of peripheral blood mononuclear cells(PBMCs) and Derrnato-phagoides pteronyssinus(Der p) J-stimulated PBMCs from Der p-sensitized atopic asthmatics, Der p-sensitized healthy atopits, non-atopic asthmatics and healthy non-atopics. The suppressive effect of IFN-y on cytokine production of Der p J-stimulated PBMCs was also examined. The PBMCs from atopics showed higher IL-4 and IL-5 production in response to PHA +TPA and higher IFN-gamma production in response to Der p Jq compared with non-atopits. The Der p J-stimulated PBMCs from atopics showed a tendency of increased IL-5 production in response to Der p J and higher IL-4 and IL-5 production in response to PHA+TPA compared with non-atopics. IL-5 production of Der p J-stimulated PBMCs from atopics was suppressed by IFN It is suggested that an imbalance in IL-4, IL-5 and IFN-y production is a feature of the atopic state. The TH2 characteristics of allergen-stimulated PBMCs could be regulated by IFN-y.

Tubulovillous adenoma of the stomach is an intermediate between tubular and villous adenoma, and may exhibit both growth patterns. Pedunculated tubulovillous adenomas behave clinically and pathologically like tubular adenoma and sessile tubulovillious adenomas tend to behave like villous adenoma., stamach is unusual site of involvement. Tubulovillous adenoma of the stomach has a great tendency to undergo malignant change. Malignant Change are correlated with polyp size and the proportion of villous componancy. And those in the stomach are highly assoeiated with an independent gastric carcinoma. Endoscopic biopsy may confirm the diagnosis but may give false positive results for malignant neoplasm and therefore should not delay, treatment. After diagnosis, surgical resection is mandatory and subsequent radiological or endoscopic follow-up is essential. Recently We experienced a 46-year-old female patient whio had a large tubulovillous adenoma of the stomach with careinomatous change and reviewed this case with references.

BACKGROUND/OBJECTIVES: Food composition databases are necessary for assessing dietary intakes. Developing and maintaining a high quality database is difficult because of the high cost of analyzing nutrient profiles and the recent fast-changing food marketplace. Thus, priorities have to be set for developing and updating the database. We aimed to identify key foods in the Korean diet to set priorities for future analysis of foods. SUBJECTS/METHODS: modified the US Department of Agriculture's key food approach. First, major foods were analyzed, contributing to 75%, 80%, 85%, or 90% of each nutrient intake. Second, the cumulative contributions to nutrient intakes were compared before and after excluding the foods least commonly consumed by individuals. Third, total nutrient score for each food was calculated by summing all percent contributions times 100 for nutrients. To set priorities among the foods in the list, we sorted the score in descending order and then compared total percent contributions of foods, within the 100, 90, 85, 80, and 75 percentiles of the list. Finally, we selected the minimum list of foods contributing to at least 90% of the key nutrient intake as key items for analysis. RESULTS: Among the 1,575 foods consumed by individuals, 456 were selected as key foods. Those foods were chosen as items above the 80 percentile of the total nutrient score, among the foods contributing at least 85% of any nutrient intake. On an average, the selected key foods contributed to more than 90% of key nutrient intake. CONCLUSIONS: In total, 456 foods, contributing at least 90% of the key nutrient intake, were selected as key foods. This approach to select a minimum list of key foods will be helpful for systematically updating and revising food composition databases.

BACKGROUND: CMV Antigenemia (CMV-Ag) assay and polymerase chain reaction (PCR) have been introduced as exponents of a new generation of tests for the detection of CMV infection. So we compared Roche Amplicor test with CMV-Ag assay to evaluate their clinical usefulness. METHODS: CMV-Ag assay using CMV-vueTM kit (INCSTAR Co., U.S.A.) detects pp65 antigen in leukocytes by immunoperoxidase detection system (positive; stained nucleus > OR =1). Amplicor CMV test (Roche Diagnostic Systems, Inc., Branching, NJ, USA) using plasma or serum is based on PCR amplification of target DNA using CMV specific biotinylated primer and hybridization of the amplified products to the probe and subsequent colorimetric detection of amplified DNA. RESULTS: Of the bone marrow transplanted 73 cases, eleven cases showed discrepancy between the two methods. Of these 10 cases those showed positive results only by Amplicor CMV test, 9 cases turned out to be true positive by the follow-up test and clinical manifestation. And the remaining one case was thought to be false positive. One case which showed positive result only by CMV-Ag assay was proved to be true positive. Consequently, CMV-Ag assay had sensitivity of 73.5% and specificity of 100%, Amplicor CMV test had 97.1% and 97.4%, respectively. Amplicor CMV test detected CMV DNA average 16.3 days before the onset of clinical manifestation and sustained until 10 days after symptoms disappearance, otherwise CMV-Ag assay detected mean 3.8 days earlier and sustained 4.2 days after. CONCLUSIONS: Amplicor CMV test is more sensitive, rapid and longer sustained method than CMV-Ag assay but it lacks quantitation.

BACKGROUND: As single donor platelets (SDP) has been increasingly used, the quality of SDP, especially apheresis-induced platelet activation, has become a major issue. This study evaluated the activation of SDP platelets prepared with three different cell separators that are currently being used at the Korean Red Cross. METHODS: CD62p, CD63 and CD42 were measured in 35 units of SDP prepared with Amicus (Baxter, Deerfield, IL, USA), MCS+ (Haemonetics, Braintree, MA, USA), or Trima (Gambro BCT, Lakewood, USA) using flow cytometry. RESULTS: Expression of CD62p gradually increased with storage time, but no difference in expression was noted between cell separators. Expression of CD63 also increased with storage time and platelets prepared with the Amicus displayed significantly higher CD63 expression 72 and 120 hours after collection compared to those prepared with MCS+ and Trima. Expression of CD42b tended to decrease with storage time, but this was only significant for Amicus 120 hours after collection. No difference in CD42b expression was noted between cell separators. CONCLUSIONS: Platelet activation increased with storage time, and platelet activation was more pronounced in the platelets prepared with the Amicus. However, because in vitro results of platelet activation does not necessarily reflect in vivo platelet function and survival, additional studies are needed to clarify clinical effectiveness of activated platelets.

Pagonimus Westmani, occuring as an important human infestation of the lung, is widely distributed in the Far East ; Korea, Japan, China and the Philippines. Since Otani found the parasites for the first time in the human brain in 1887, it has been established that cerebral infestation occurs with the highest frequency among extrapulmonary involvement. In 0.8 to 25 percent of patients infested with the lung flukes cerebral paragonimiasis may be developed. The larvae may procedure arachnoiditis, abscess, fibrous cystic lesions and granulomas in the brain. Based on a review of the literatures and upon the 7 cases of cerebral paragonimiasis which have been observed by the authors at the National Medical Center, Seoul, Korea, the following points are stressed. 1) Males had a significantly higher prevalence than females. Cerebral paragonimiasis was most commonly found in young adults(16 to 25yrs). 2) Clinically the patients with cerebral involvement were characterized by Jacksonian type of epilepsy, headache and visual disturbance. Mental deterioration, hemiplegia, hemihypesthesia, homonymous hemianopsia and optic atrophy were the five major signs. 3) The patients having symptoms for less than 6 months developed mild leukocytosis in many cases. All the cases of cerebral paragonimiasis revealed positive reaction in the intradermal tests with purified antigens of P. Westermani. 4) On skull films multiple round or oval cystic calcification was diagnostic value for cerebral paragonimiasis. On angiogram vascular staining and abnormal vessels were not disclosed. On pneumoencephalogram subcortical atrophy or filling defect of the ventricle may be showed. 5) The predilection area of the granuloma and fibrous cystic mass were the occipital, posterior parietal and posterior temporal lobes. 6) The patients with chronic stabilized cerebral paragonimiasis. having intractable symptoms and signs, could not be improved with Bithionol treatment. But headache, vomiting, visual disturbance, facial weakness and especially intractable seizure were improved in our cases treated with surgical operation.

The adverse drug reaction(ADR) monitoring is very critical in healthcare. However, the number of actual reported cases on ADR has been extremely low in Korea compared to other countries. This study was designed to find out a way to expedite ADR reporting in a general hospital, where many drugs are used daily. In this study, a newly developed ADR monitoring system has been implemented and was evaluated for its outcome. In addition, a survey was conducted for two groups, 50 ADR reporters and 100 non-reporters, to identify factors which can affect the ADR reporting. The new system was a multidisciplinary program based on a voluntary reporting involving doctors, nurses and pharmacists. The reporting methods were diversified such as ADR report sheet, computerized Order Communication System(OCS) consultation and drug refund reports. After a year since the system has been implemented, the number of reported cases was 158, which was 131 times higher than that of the pre-implementation period. Doctors reported the most(75 .3%), and ADR report sheet was used most frequently(57%). In terms of severity of ADR 74.7% was mild, 22.8% moderate and 2.5% severe. The unexpected ADRs were 7.6%. Both groups had a high degree of awareness of the necessity of monitoring and basic knowledge of ADR. Important factors affecting ADR reporting were frequency of ADR findings(p<0.01), awareness of the fact that the institution was designated as an ADR monitoring institution(p<0.001) and participation in the education program(p<0.01). In conclusion, modification of the reporting system and ongoing and systematic education are needed to improve ADR monitoring in a general hospital.
