The main objectives of this study were to know the prevalence of cerebrovascular disease, to find the important risk factors of cerebrovascular diseases. This study is a part of Eumseong Community Health Project supportes by GTZ(West German Government). 116 perceived cases of cerebrovascular disease were first screened by health interview and examinations and 80 cases were diagnosed as a cerebrovascular group. For comparison, 80 cases were matched with their neighbor controls of the same sex and the similar age. 1. The prevalence rate for cerebrovascular diseases was 476.3 per 100,000 population which is considered to be very high compared with that of other countries. Age adjusted rate for cerebrovascular diseases was 261.6 per 100,000. 2. Among the risk factors examined for the association with cerebrovascular diseases by case-control study, and analyzed by paired marginal test(McNemar's chi-square-test) and odds ratio, only hypertension showed high significant statistical association.

BACKGROUND: Respiratory syncytial virus (RSV) is the most common cause of lower respiratory infection in infants and young children, but the pathogenesis of RSV-induced inflammation is not well defined. MATERIAL AND METHOD: In order to examine the potential interactions between virus-infected airway epithelial cells and neutrophils, we studied the ability of neutrophils to adhere to yirus-infected airway epithelial cell monolayers by myeloperoxidase assay. Also we measured the ability of airway epithelial cells to secrete interleukin-8(IL-8) and inter-cellular adhesion molecule-1(ICAM-1) in virus-infected airway epithelial cell cultures by enzyme-linked immunosorbent assay(ELISA). The degree of IL-8 and ICAM-1 gene expression in the RSV-infected BEAS-2B cell cultures were analyzed by reverse transcription-polymerase chain reaction(RT-PCR). RESULTS: The RSV-infected BEAS-2B cell resulted in significantly enhanced level of neutrophil adherence compared to the uninfected control(p (0.001). IL-8 and ICAM-1 production significantly increased by RSV infection(p<0.05). There was a significant positive correlation between neutrophil adherence and IL-8 level(r=0.73, p=0.002), and ICAM-1 level (r=0.843, p=0.001) in RSV-infected cells. The degree of both IL-8 and ICAM-1 mRNA expression increased in the RSV-infected cells compared with the uninfected ones. CONCLUSION: These results suggest that RSV infection significantly enhances the production of IL-8 and ICAM-1 in airway epithelial cells which then results in increased neutrophil adherence.

Endobronchial tuberculosis is frequently associated with lymphadenopathy, bronchial stenosis, atelectasis which needs to be differentiated with other pulmonary disease. Authors are presenting 25 cases of endobronchial tuberculosis which were confirmed boy bronchoscopic biopsy and AFB smear and/or culture. The study was done on patients who visited Yeungnam University Hospital from May 1983 to July 1985. The following results were obtained: 1. Of the 25 cases, 8 cases were male and 17 cased were female (male:female=1:2). 32 percent of the cases was older than 60 years of age. 2. Abnormal findings on chest x-ray were seen on 22 cases of 25 cases (88%) and its most predilective site was right upper lobe (24%). 3. Symptoms were coughing (56%), hemoptysis, hoarseness, chest pain, dyspnea and fever in orders. 4. The positive results were obtained in 73 percent of sputum AFB smear (11 cases of 15 cases). 60 percent of AFB culture (3 cases of 5 cases) and 58 percent of bronchoscopic biopsy (14 cases of 24 cases). 5. Complete pulmonary function test was done on 19 cases and showed normal result in 6 cases, restrictive pattern in 8 cases and small airway dysfunction in 5 cases. No case of obstructive airway disease was detected. 6. Associated disease were hypertension (2 cases), tuberculous meningitis (1 case), diabetes mellitus (1 case), and cataract (1 case). 7. The site of bronchoscopic lesion on bronchoscopic examination were as follow; 8. All 25 patients were treated with anti-tuberculosis therapy and 6 patients were treated with additional steroid therapy because of severe respiratory symptom and showed dramatic improvement of symptom as well as lung function.

Evlauation of pulmonary vascular changes and pre-and postoperative hemodynamic findings were performed in 25 patients who had ventricular septal defect associated with sevese pulmonary hypertension. Lung biopsy were done preoperatively in two patients and during operation in twenty three patients. Also the postoperative systemic and polmonary arterial pressure were obtained about 10-20 minutes after the cardiopulmonary bypass. The results were as follow: 1) There was no relationship between the severity of pulmonary vascular changes(Health-Edwards classification) and the patients age(X2=4.4427, P=0.2175). 2) There was a good correlation between preoperative ratio of pulmonary to systemic vascular resistance(Rp/Rs) and ratio of pre-and postoperative pulmonary to systemic arterial pressure(r=0.4846, P<0.05). 3) There was a significant correlation between the degree of medial wall thickness and preoperative Rp/Rs(r=0.6535, P<0.005). 4) There was no correlation between perioperative hemodynamic findings and medial wall thickness in the patients aged below 2 years.

BACKGROUND/AIMS: Transfection of the hepatitis B virus (HBV) genome requires the cloning of tandem HBV sequences inserted into a plasmid vector, which is usually screened for by the restriction enzyme digestion of plasmid minipreparation from at least a dozen of bacterial colonies. The aim of this study was to develop a simple alternative screening method for bacterial colonies harbouring tandem HBV sequences by a PCR. METHODS: A set of polymerase chain reaction (PCR) primer was designed to detect the bacterial colonies harbouring "head to tail" dimeric HBV DNA. PCR which amplifies the head to tail junction site of two tandem HBV molecules was performed. RESULTS: PCR products with appropriate size (1.2kb) were obtained. The accurate detection by PCR screening technique was confirmed by enzyme digestion. CONCLUSIONS: These results suggest that PCR screening technique is a simple and rapid method for the identification of bacterial colonies containing tandem HBV sequences.

Multiple symmetric lipomatosis is a rare disease and affects almost exclusively middle aged man, usually with a background of excessive a alcohol intake. The disease is characterized by progressive growth of subcutaneous fat masses which are located symmetrically at neck, shoulders, chest, abdomen and groin, and which subsequently penetrate deeply into the surrounding spaces and structures with symptomatic compression of deep organs, such as trachea. A recent survey revealed a high incidence of sometic and autonomic neuropathy. The exact cause of the disease is not known, but a hyperplastic mechanism has been postulated, with in vitro studies demonstrating a defect in adrenergic-stimulated lipolysis of lipomatous tissue. We have experienced two cases of multiple symmetric lipomatosis. Case 1 was a 59-year-old male, complaining of slowly enlarging doughunt ring-shaped mass at his neck. He had a habit of excessive alcohol intake for many years. The subcutaneous mass at the neck was excised. The pathology report described the specimen as "normal adipose tissue". Case 2 was a 49-year-old male, complanining of slowly enlarging multiple symmetric masses at the neck, shoulders, chest, abdomen, flank and groin over a period of 6 years. He also complained of mild muscular weakness. He had a habit of excessive alcohol intake for many years. The subcutaneous mass in the neck was excised. The specimen had a tendency to form globular masses and microscopically indistinguishable from mature adipose tissue.
