In our preliminary study to find antiviral or antitumor agents from Korean natural products, we found that the Shope fibroma virus (SFV) induced fibromas reaching maximum size at 5~6 days with spontaneous disappearance at 15~20 days after SFV intracutaneous inoculation into Korean domestic rabbits. However, the sizes of fibromas of rabbits at day 5 after virus inoculation were significantly different individually. Assuming that the variation of tumor size was due to either susceptibility or the preexisting antibodies against SFV in the Korean domestic rabbits, the rabbits were checked for the antibodies against SFV by IFAT using SFV infected RKl3 cells. The antibody positive rate of normal Korean domestic rabbits was 32.8% and the sizes of the fibromas of the positive rabbits were significantly smaller than those of negative rabbits (p<0.0001). The fibroma sizes were dependent on the antibody titers of rabbits to SFV. The sizes of fibromas after inoculation of SFV into immunized rabbits were about one tenth of those by the first inoculation into normal rabbits. This is the first report on the antibody prevalence against SFV among normal Korean domestic rabbits and it suggest the existence of a wild fibroma virus or related virus in Korea.

PURPOSE: The purpose of this research was to find out factors affecting job stress and job satisfaction of nurses working at the welfare centers. METHODS: This study was performed with 140 nurses who were working at or had retired within 1 year from general welfare centers in Seoul during the period from March 29 to February 29 2004. We used a questionnaire asking about general characteristics. work characteristics. stress factors and job satisfaction. We analysed 103 subjects who replied to the questionnaires. RESULTS: The mean job stress level was 2.84 out of 5 and. as for the sub-factors of job stress. income was 4.19, career development 3.69, service environment 3.26 and support system 1.90. The mean job satisfaction level was 3.32 out of 5 and. as for the sub-factors of job satisfaction, job control was 3.58, efficiency of organization 3.27, job burden and responsibility 2.92 and role ambiguity 2.25. When the nurses' job stress was compared according to their general and work characteristics. stress level was significantly high in nurses who had a short experience. were working at the department of senior welfare center. or were the only staff at their workplace (p<0.05). In addition. satisfaction level was significantly high in nurses who were working at the department of senior welfare center and medical welfare team. were the only staff at their workplace or had a heavy work load (p<0.05). According to the results of multiple regression analysis. job stress level was influenced by age (R2=0.212, p<0.01). and job satisfaction level by the number of staffs and work load (R2=0.272, p<0.1). CONCLUSIONS: The results of the study suggest that good atmosphere should be made up to communicate between the departments at the workplace in order to lessen job stress and enhance job satisfaction of nurses working at welfare centers. In addition. role division and job duties among special staffs should be reviewed in order to achieve high efficiency in performing job duties.

A total of 47 preoperative CT scans in patients with renal cell carcinoma were retrospectively reviewed and compared with surgical findings to assess the accuracy of CT for determining the perinephric tumor extension. CT criteria for perinephric extension were hazy ill-defined tumor margin, perirenal nodule and fascial thickening. Regardless of the tumor stage, the accuracy of CT in detecting perinephric extension was 76.6%(36/47), with a sensitivity of 88.9% (16/18) and specificity of 68.9% (20/29). The cause of understaging (n=2) was microscopic infiltration of the perinephric space. The causes of overstaging were tumor infiltration to the renal capsule (n=5), partial adhesion with the perinephric fat (n=3) and renal vein thrombosis (n=1). A smooth clear tumor margin is highly reliable sign for stage I but infiltrative findings onto renal capsule and perirenal fat could be considered stage I.
