PURPOSE: The study tried to suggest the ways to improve the national disability welfare information projects with evaluating the present condition of the projects. METHOD: Firstly, the study analyzed the disability information system and disability websites. Secondly, the study found out the problems of the registration of disability and management system through the situation analysis. Finally, the study conducted a survey of the disabled and the information system workers and performance evaluation of the information system. RESULTS: The study offered a proposal of The Disability Unity Management System(DUMS) for the disability registration and management. When the disabled visit the hospital or the public health center, their information is registered automatically in The Disability Unity Management System(DUMS), which helps not to miss out the disability registration. Through this system, they are given the proper service which they need, and the information can be shared with the facilities providing the service for the disabled. CONCLUSION: The Disability Unity Management System(DUMS) contributes significantly in avoiding the repetition of the support for the disabled and improving the quality of service.

Inflammatory pseudotumors of the bronchus have been reported infrequently. Histologic diagnosis remains difficult because of their Polymorphic histologic characteristics and confusing terminology, which are also the problems in the diagnosis of intrapulmonary pseudotumors. We report a case of inflammatory pseudotumor in the left main bronchus which occurred in a 37-year-old man. Histologically, the main portion of the tumor was composed of pale eosinophilic spindle shaped cells covered by respiratory epithelium with squamous metaplasia. Mononuclear inflammatory cells, including plasma cells but acute inflammatory cells were also present in the superficial portion.

Strumal carcinoid of the ovary is a rare turkor characterized by an intimate mixture of thyroid follicles and carcinoid. Herein is reported an ovarian strumal carcinoid in a serous cystadenoma from a 27-year-old pregnant woman. The thyroid follicular epithelial cells had immunohistochemically thyroglobulin and carcinoid tumor cells contained neuron-specific enolase, chromogranin and carcinoembryonic antigen. In addition, carcinoid cells showed neuroendocrine granules ultrastructurally. Calcitonin and amyloid were not found. This tumor may be originated from pluripotent endodermal germ cells on the basis of morphologic, immunohistochemical and ultrastructural studies.

Adenomatoid tumor of the uterus is a rare benign neoplasm which has been known as mesothelial origin. Characteristically, it appears as a small nodular lesion less than 2.0cm in the myometrium of subserosal region. We describe a case of giant adenomatoid tumor of the uterus having multicystic gross appearance. A 49-year-old woman complained of vaginal bleeding. The tumor was an intramural mass with maximum diameter of 10 cm and located at posterior wall of the uterus. Histologically, the tumor was composed of multiple cystic cavities of variable size lined by flattened cells, lying among thin septa of connective tissue. Immunohistochemically, the cells are positive for low molecular weight cytokeratin(CAM 5.2) and are negative for factor VIII.

To evaluate the tissue expression rate and pattenr of HBsAg and HBcAg in tumors and peritumoral livers, an immunohistochemical study was undertaken on 47 surgically resected hepatocellular carcinomas(HCCs). The results are as follows. 1. Patient's sera were positive for HBsAg in 40 cases(85.1%). In the remaining 7 cases, the tumor and peritumoral liver expressed neither HBcAg nor HbSaG, suggesting that they were caused by other etiologies than hepatitis B virus. 2. The peritumoral liver had HBsAg and HBcAg in 95.0% and 27.5% among the 40 cases, respectively. But the tumor expressed HBsAg in 50.0% and HBcAg in none. 3. The expression of HBsAg within the tumor and both HBsAg and HBcAg in the peritumoral liver tended to be more frequent in the pretreated cases before surgery. 4. Edmondson-Steiner grade IV tumors revealed a lower expression rate of HBsAg than the low grade tumors(p<0.05). Incases with cirrhosis at peritumoral tissues, HBcAg was less frequently found than in those without cirrhosis. The majority of tissue HBsAg and HBcAg was represented as groups of positive cells. These results suggest that, during the development and progression of HCCs, the HBcAg containing cells are repeatedly removed and the HBcAg negative cells are selected, because cellular expression of HBcAg is the target of host immune response.

Clear cell meningioma is a recently recognized morphologically unique entity. It shows no sex predilection, affects primarily the lumbar region, and the cerebellopontine angle. Despite its benign appearance, it may be aggressive, particularly in intracranial cases. All lesions are moderately cellular, with the exception of stromal hyalinization. The tumor consists largely of a sheet- like or somewhat lobular pattern of polygonal cells, the cytoplasm of which is clear. No close association is noted between the recurrence or the clinical outcome and factors such as mitotic activity, the PCNA index, and the DNA ploidy status. But the MIB-1 proliferation index is appreciably higher in recurrent tumors. We experienced a case of clear-cell meningioma showing a characteristic histologic finding. A 39-year-old man was admitted due to the recent onset of right-sided, facial-nerve palsy, left hemiparesis and general weakness. A CT scan of the head showed a well defined mass in the petroclival area. After surgical resection, the patient was in good condition, but 1 year later symptoms recurred. A CT scan of the head showed a huge, recurrent petroclival tumor with adhesion to the surrounding brain parenchyme.

Gastrointestinal angiodysplasia is a distinct disease entity which causes frequent gastrointestinal bleeding. It predominantly arises at the stomach and duodenum in the upper gastrointestinal tract and cecum and ascending colon in the lower gastrointestinal tract. The general histological finding of the angiodysplasia is a submucosal vascular ectasia and tortuosity. We have experienced two cases of the intestinal angiodysplasia. The first case occurred on a jejunum in a 22-year-old woman who had anemia. The second case occurred on a sigmoid colon in a 59-year-old man who had constipation. In addition to the general histologic finding of the angiodysplasia, the microscopic findings of the first case revealed some capillary hemangioma-like areas; and in the second case, there was a marked ischemic change and the thickening of the wall.

BACKGROUND: Elecsys 2010 immunoassay system is based on the electrochemiluminescence immunoassay using a ruthenium (II) tris (bipyridyl) label. Since it was the first time to use the system in our laboratory, we would like to evaluate the analytical performances (precision, linearity and recovery rate) and correlation with radioimmunoassay (RIA) and microparticle enzyme immunoassay (MEIA) methods. METHODS: We used precicontrol tumor marker (TM1, TM2) for alpha-fetoprotein (AFP), prostatic specific antigen (PSA) and carcinoembryonic antigen (CEA), Precicontrol universal (Ul, U2) for triiodothyronine (T3) and thyroxine (T4), Precicontrol-TSH for thyrotropin (TSH) and pooled serum for the evaluation of precision and recovery rate. Patients' sera were used for the linearity and comparison study. RESULTS: The coefficients of variatron of Imprecision study were below; 4.0%, 8.7% and 10.2%, respectively in the within-run, within-day and between-day analysis. The recovery rates were 100.5%, 96.1% and 102.5%, respectively in T4, TSH, and AFP. The linearity were y=1.02x-0.182(r=0.99) for T4, y=1.01x+0.12 (r=0.99) for TSH and y=1.01x+0.54(r=1.00) for AFP. T3, T4, TSH, CEA and PSA results showed good correlation with RIA (r>0.90), but AFP showed r=0.88. Also, AFP, CEA and PSA results showed excellent correlation with AxSYM (r>0.99). CONCLUSION: Elecsys 2010 immunoassay system showed excellent precision, recovery rate, clinically acceptable linearity and good correlation with the results obtained by RIA and MEIA methods.

Acetylcholine is one of the major neurotransmitters in visual system of rats. Cholinergic, serotonergic and gamma-aminobutyric acid(GABA) ergic projections are known as modulators of visual processing. The purpose of this study was to examine the effects of unilateral orbital enucleation on the amount of acetylcholine and its receptor bindings in dorsolateral geniculate body, superior colliculus and visual cortex of rats, and on motor activites. The amount of acetylcholine was measured by gas chromatography; whereas [3H]quinuclidinyl benzilate(QNB) bindings to muscarinic receptors were examined by autoradiography. Motor activity was measured by activity meter for 24 hours. The results of this study were as follows: 1. The amount of acetylcholine in superior colliculus significantly increased at 1 week after enucleation, but it decreased at 2 and 4 weeks after enucleation. In visual cortex, the amount of acetylcholine did not change at 1 week after enucleation, but it significantly decreased at 2 and 4 weeks after enucleation. 2. After enucleation, [3H]-QNB binding to muscarinic receptors gradually decreased over the 4 weeks in dorsolateral geniculate body, superior colliculus and visual cortex. 3. Locomotor activity of rats did not show any change at 1 week after enucleat ion, but it decreased at 2 and 4 weeks after enucleation. In conclusion, unilateral orbital enucleation resulted in a reduction in the amount of acetylcholine and muscarinic receptors in rat visual system, which was speculated to be a major cause of a decrease in physical activity.

PURPOSE: MEN1 gene mutation causes multiple endocrine neoplasia type 1. It also suggests that somatic MEN1 gene mutation plays a role in sporadic endocrine tumor. In this study, we examined whether somatic mutations of MEN1 gene are responsible for sporadic parathyroid tumors and correlate with clinical manifestations of parathyroid tumors. METHODS: Somatic mutation of MEN1 gene in the formalin-fixed, paraffin-embedded parathyroid tumor tissue from 8 adenomas, 2 carcinomas and 1 hyperplasia were analyzed by direct sequencing. Clinicopathological parameters were reviewed from medical records and compared with the mutational data. RESULTS: Eight of eleven (73%) sporadic parathyroid tumors had somatic MEN1 mutations of 14 different types. In the 14 types, 13 were a point mutation which is composed of 8 missense mutations, 2 nonsense mutations and 3 silent mutations. One of 14 types is a frameshift deletion of 27 base pairs in exon 2. Somatic mutation was frequent in the exon 2 and exon 10. Four types of polymorphism were found. There was no correlation between the presence of mutations and clinicopathological phenotype of parathyroid tumors. CONCLUSION: This result suggests that somatic mutation of MEN1 gene plays a definite role in sporadic parathyroid tumor formation.
