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.

Tumor angiogenesis, the development of new blood vessels by tumor, is a widely observed phenomenon associated with the growth of human solid tumors. To investigate how tumor angiogenesis correlates with other prognostic features i.e. menopause status, tumor size, lymph node metastasis, mitosis, angioinvasion, estrogen receptor (ER), p53 protein expression, histologic grade and clinical stage, we counted microvessels by immunohistochemistry using antibody for CD34 antigen in 56 cases of invasive breast carcinoma (27 with and 29 without axillary lymph node metastases) and 20 cases of non-inflammatory benign breast lesion. CD34 antigen is expressed on the surface of hematopoietic progenitor cells and more sensitively expressed than factor VIII in vascular endothelial cells. Microvessel count (MVC) was performed at a single hot field of 200x magnification (0.74 mm2 per field). The results are summarized as follows; 1) The mean MVC of invasive carcinoma and benign breast lesion were 92.0+/-54.4 (range, 7-237) and 20.7+/-16.6 (range, 4-73), respectively (p<0.0001). 2) Although MVC had no correlation with all other prognostic factors i.e. menopause status, tumor size, lymph node metastasis, mitosis count, angioinvasion, ER, p53 protein expression, histologic grade, and clinical stage (p>0.05), MVC had a tendency to increase in tumors with axillary LN metastasis or without ER expression. 3) Without correlation with MVC, ER (+), angioinvasion (-) and higher histologic grade correlate to significantly higher mitosis count (p<0.0005). Also, angioinvasion correlate to a significantly higher histologic grade (p<0.05). In conclusion, angiogenesis is related to tumorigenesis, but MVC may not be related to other clinicopathologic factors.

OBJECTIVE: To determine the significance of high risk human papilloma virus (HPV) infection and involvement of the resection margins of cervical cone biopsy specimens removed by loop electrosurgical excision procedure (LEEP) in the management of cervical intraepithelial neoplasia (CIN III). METHODS: Records of 506 LEEP procedures performed due to abnormal Pap result between December 1995 and December 1998 were reviewed. Among them, 232 cases with histologically proven as CIN III in LEEP and follow-up Pap smear more than 6 months was available were assessed. All patients were assigned according to HPV infection and resection margin involvement in LEEP, and recurrence rate in the follow-up was compared with reference to post-LEEP treatment regimen, observation or hysterectomy in each group. RESULTS: Of 232 cases reviewed, 10 cases(4.3%) were ASCUS, 19 cases(8.2%) were LSIL, 199 cases(85.8%) were HSIL, and 4 cases(1.7%) were invasive cancer in initial Pap smear. Abnormal Pap result in the follow-up was as follows: 4 cases of ASCUS, no case of LSIL, and 6 cases of HSIL. Excluding ASCUS, the overall recurrence rate in the follow-up was 2.6%(6/232). HPV positive was 164(70.7%) and HPV negative was 68(29.3%) in the LEEP specimen. Of 164 HPV positive, 41 were followed up without further treatment and 123 with hysterectomy. There was no significant difference in the recurrence rate between the two groups(P=0.41). Of 68 HPV negative, 27 were only followed up and in 41, hysterectomy was done. And also, there was no significant difference(P=0.32). Of 232 cases, resection margin was positive in 167(72.0%) and negative in 65(28.0%). Of 65 margin negative, 29 were followed up without further treatment and 36 with hysterectomy. There was no significant difference in the recurrence rate between the two groups(P=0.36). Among 167 margin positive, 39 were only followed up and in 128 hysterectomy was done. Recurrence rate was significantly higher in followed up only group(P=0.04). CONCLUSION: HPV infection in LEEP specimen was not helpful in deciding post LEEP treatment modality in CIN III patient. But, when resection margin was positive, hysterectomy should be performed because by doing so, recurrence rate was significantly lower than when only follow up was done.

PURPOSE: Recently in light of the development in immunology, interferon- e and inter- leukin-2 or combination therapy with anticancer drugs have been performed. This study aims to verify and compare the efficacy of therapies using interferon- a alone, interferon- a plus vinblastine, and interferon- a plus interleukin-2 plus 5-fluorouracil (5-FU) plus 13-cis retinoic acid (13cRA) in patients with advanced renal cell carcinoma. MATERIALS AND METHODS: A total of 29 patients were randomly assigned to receive treatment with either interferon- a alone or interferon- a plus vinblastine or interferon- a plus interleukin-2 plus 5-FU plus 13cRA from December 1989 to May 1998. The most frequent metastatic sites were the lung, lymph nodes, bone, liver, and brain. We studied the response rates, survival period, and complications of each regimen. RESULTS: Responses were achieved in 1 out of 1~5 patients (6.73?o) on interferon- a alone (partial responses lasting 13 months), 1 out of 9 patients (11.1%) on interferon- e plus vinblastine (partial responses lasting 25 months) and 1 out of 5 patients (20.0%) on interferon-a plus IL-2 plus 5-FU plus 13cRA regimen (partial responses lasting 14 months). The median durations of survival were 18, 33, and 23 months respectively. The overall response rate was 10.3% and overall median duration of survival was 19 months. The most common side effects were flu-like symptom such as fever, chills (93.1%), skin symptom such as erythema, pruritus (31.0%), G-I symptom such as nausea, vomiting (17.2%), netropenia (10.3%), abnormal LFT (10.3%), and thrombocytopenia (3.4%). CONCLUSIONS: This study confirms the manageability and tolerability of several regimen used. There is no significant differences in response rates and survival duration among the regimens used in this study. The effective immunotherapy in patients with metastatic RCC should be evaluated by further studies of larger patients groups even though a minority of patients responded.

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.
