BACKGROUND/AIMS: Hepatitis C virus(HCV) was known to most common etiologic agent of chronic liver disease in United states and Japan. Although hepatitis B virus(HBV) was well known to be a its major etiologic agent in Korea, it has been showed that HCV and HBV are associated with liver cirrhosis and hepatocellular carcinoma as major causative agent of chronic liver disease. Interferon alpha therapy is generally accepted as effective single agent for chronic hepatitis or to decrease the chronicity of acute hepatitis C. So, we evaluated the efficacy of interferon alpha in hepatitis C. METHODS: 46 patients who were positive for anti-HCV antibody and HCV RNA were included in this study. Liver biopsy was per formed on all patients and all of them were tested as negative for serum HBsAg, anti Hbe. Patients were divided into 2 groups . 30 patients received interferon therapy(treated group) and 16 patients received no therapy(untreated group). We compared the change of liver function test and HCV RNA before and after therapy between two groups. Treated group was subdivided into 5 groups according to response to interferon therapy '. Non-response, partial response, breakthrough, relapse and sustained response. RESULTS: 1) The mean age and sex distribution were 49.9 year old, male 19, female 11 in treated group and 48.7 years, male 12, female 4 in untreated group. 2) The number of patients with acute hepatitis, chronic persistent hepatitis, chronic active hepatitis and liver cirrhosis were 1, 2, 23, 4 in treated group and 0, 1, 12, 3 in untreated group, respectively. 3) The mean follow up period was 1.7 year and 2.3 years in treated and untreated group, respectively. 4) The activity of serum ALT before and after therapy were 195+ 134.6 IU/L, 87.4+ 40.5 IU/L and 186.7+ 106.4 IU/L, 157+ 87.1 IU/L in treated and untreated group, respectively. Serum ALT after therapy in treated group was significantly lower than untreated group(P<0.01). 5) The number of patients for patterns of reponse in treated group was non-response 5, partial response 8, breakthrough 1, relapse 4, sustained response 12 and there was no difference in age among them(P>0.05). 6) The case of negative conversion for HCV RNA in treated group was 12, but there was no case in untreated group. 7) Sex distribution of sustained response was 6(31% ) of 19 male, 6(54.5%) of 11 female and 12 patients(40.0%)(1 of 1 patients with acute hepatitis, 1 of 2 chronic persistent hepatitis, 10 of 23 chronic active heaptitis) included in sustained reponse, but any patients with liver cirrhosis had response. 8) Mean total dose and duration of interferon therapy was non-response 10353.6 million unit(MU)/5.8month(M), partial response 20025.06MU/6.4 M, breakthrough 36000.0MU/5.0M, relapse 11700.0MU/3.3M, sustained response 28100.0MU/6.6M, respectively. 9) 3 of 7 patients who were followed up over 1 year in sustained response and mean time to the relapse was 2.2 years. CONCLUSION: Our results showed that interferon alpha therapy is effective in patients with hepatitis C and further study and attempts should be performed to augument the efficacy of interferon alpha for the treatment of hepatitis C.

Malakoplakia is a chronic inflammatory disease. Approximately 75% of cases are located in the genitourinary system. The etiology remains obscure but it appears related to an underlying infection. It mainly occurs in females in a 4:1 ratio, and the peak age is in the sixth decade. Apart from the symptoms associated with urinary tract infections, the clinical manifestations are usually unremarkable. Here, we report a 44-year-old woman suffering from an intraabdominal mass, with histology that was specific for a malakoplakia of the bladder. This case was difficult to differentiate from a urachal cancer.

OBJECTIVES: Copper and Zinc, the trace elements of a living body, take a part in immunologic mechanism and induce the pulmonary fibrosis which is the pathologic progress of pneumoconiosis. This study was performed to assist the identification of the pathologic process of pulmonary fibrosis in pneumoconiosis. METHODS: The subjects of this study was 200 diagnosed persons as pneumoconiosis, of whom 100 persons was the visitors in the outpatients departments of pneumoconiosis and 100 admissive pneumoconiosis patients. The serum copper and zinc are measured and com pared. RESULTS: The mean serum copper concentration of visitor group was significantly higher than that of control group, and that of stage V3 subgroup of visitor group was highest because of their advanced fibrosis. But, there was not the difference of serum copper concentration between patient and control group. We thought that the reason was poor nutritional and health status of the patient. The mean of serum zinc concentration of visitor and patient control was lower than that of control group. As the degree of pulmonary fibrosis was more severe from stage Vl, V2, V3 of visitor to stage Pl, P2, P3 of patient, the mean of serum zinc concentration was lower. The ratio of serum copper/zinc of visitor and patient was higher than that of control, and that of patient was higher than that of visitor. Those results showed that the ratio of serum copper/zinc ratio more greatly expressed the degree of progression of pneumoconiosis than only copper or zinc concentration by adjustment of nutritional and health status of the patient. CONCLUSIONS: As above study results, the degree of pulmonary fibrosis of pneumoconiosis could be estimated by means of serum copper/zinc ratio.

PURPOSE: Benign prostatic hyperplasia(BPH) describes a hyperplastic process of the stromal and epithelial elements of the prostate. The proliferative rates of each compartment in BPH may vary individually and the prostate is topographically not affected in a uniform way. The proposed mechanism of alphas-blockers in the treatment of BPH is the decrease of prostatic urethral resistance by relaxing the prostatic smooth muscle component present in the stroma. The purpose of this study is to search the effect of alphas-blockers according to histologic compositions in patients with BPH. MATERIALS AND METHODS: From January 1994 to June 1997, 74 patients were treated with alpha1-blockers(> or =1month) before prostatectomy. Of 74 patients, the international prostate symptom score(IPSS) was used in 62 patients to evaluate the severity of voiding difficulties. The clinical response to alpha1-blockers was based upon change in IPSS during medication period. According to histological compositions of prostatectomy specimen, the patients were classified into three groups: predominantly stromal type(20 patients), predominantly glandular type(21 patients) and mixed type(21 patients). RESULTS: There were 17 patients In response group and 45 patients in nonresponse group. The stromal type, glandular type and mixed type were composed of 52.9%, 17.7% and 29.4% respectively in response group and 24.4%, 40.1% and 35.5% respectively in nonresponse group. There was not statistical significant differences between clinical response of the alpha1-blockers and histologic compositions in patients with BPH(p>0.05). CONCLUSIONS: Although stromal type was predominant in response group and glandular type was predominant in nonresponse group, the relationship between the effects of alpha1-blockers and histologic compositions in patients with BPH was not statistically significant. Further evaluation will be necessary to assess the association between effects of alpha1-blockers and histologic difference of prostate in patients with BPH.

Majority of .hepatocellular carcinoma is evolved from a well differentiated cancerous condition such as hypetptastic lesions eg; adenomatous hyperplasia in cirrhotic liver or de no vo carcinogenesis and prolifenation along with dedifferentiation. Adenomatous hyperplasia is may be seen in severe acute hepatic injury, like svhmassive hepatic necrosis, or in chronic liver diseases, particularly liver cirrhosis and it has recently attracted much interest from both clinicians and pathologists because it is regarded as a precursor lesion of hepatocObdar carcinoma. Hepatic. denomatous hyperplasia resembling focal nodular hyperplasia might have developed from localized vascular changes associated with chronic liver disease, pre-existing arterial malformation and early stage of angiogenesis in hepatocarcinogenesis. .fie present a patient who developed hepatocellular carcinoma after hepatic artery ligation.

BACKGROUND: In the resection of lung cancer, pneumonectomy occupied 20~35% of all resections, and significantly high operative mortality is reported in right pneumonectomy (10~25%). The aim of this study is to identify the characteristics of morbidity, operative mortality and factors affecting operative mortality after pneumonectomy. MATERIAL AND METHOD: This study recruited the database which performed pneumonectomy for lung cancer in Korea Cancer Center Hospital from Aug 1987 to Apr 2002. RESULT: Total of 386 pneumonectomies were performed in that period. Sidedness were left in 238, right in 148; and the procedures were standard resection in 207, and extended resection in 179. Morbidity occurred in 115 cases (29.8%, 115/386). Mortality occurred in 12 cases (3.1%, 12 in 386). This mortality rate was similar to that of lobectomy (2.1%, 13 in 613) during the same period. Morbidity consisted of 42 hoarseness, 17 (9) pneumonia and ARDS, 8 empyema, 5 (1) broncho-pleural fistula, 5 reoperation for bleeding, 5 (1) arrhythmia, 1 (1) pulmonary edema, and 25 others (The number in the parenthesis is the number of mortality case for that morbidity). Several factors affecting the operative mortality were evaluated. At first, extended procedure (3.3%, 6 in 179) affected the operative mortality similar to the standard procedure (2.9%, 6 in 207)(p=0.812). Second, the rate of operative mortality in an elderly group over 60 years (5.5%, 10 in 182) was significantly higher than the younger group under 60 years (1%, 2 in 204)(p=0.016). Third, sidedness of resection affects to operative mortality. Right pneumonectomy (6.8%, 10 in 148) showed higher operative mortality than that of left pneumonectomy (0.8%, 2 in 238)(p=0.002). The group over 60 years showed higher incidence of respiratory morbidity (11.0%, 20 in 182) than that of the group under 60 years (3.4%, 7 in 204)(p=0.005). Right pneumonectomy also showed significantly higher incidence (11.5%, 17 in 148) than that of left pneumonectomy (4.2%, 10 in 238)(p=0.008). CONCLUSION: Age and sidedness of pneumonectomy were the risk factors of operative mortality and respiratory complications. Therefore, careful selection of patients and more attention perioperatively were demanded in right pneumonectomy. However, because the operative mortality is acceptable, pneumonectomy could be done safely if the pneumonectomy is necessary for curative resection of lung cancer.
