Two cases of ureteral fibrous polyp showing serpiginous filling defect on IVP are presented with characteristic radiologic features; easy flow of contrast medium around polyp. Prolapsed polyp in urinary bladder, and less ureteral obstruction or renal damage than in epithelial lesions. These rediologic findings enable to differentiation of ureteral fibrous polyps from malignant tumor, which is helpful for determining therapeutic approach.

It is well known that the bona pellucidae of mouse oocytes become 'hardened' when they are allowed to mature in vitro in the absence of serum components. To see if oocytes already undergone meiotic resumption in vivo exhibit similar zona hardening, hardening of ZP of cumulus-enclosed oocytes(CEOs) was examined after culture in vitro since their release from follicles various hours after hCG injection. When CEOs matured in vivo for 3h or longer were subjected to culture in vitro for 14h with BSA alone, zona hardening was significantly reduced compared to those cultured in vitro from the begining of maturation. However, when CEOs matured in vivo for 5h were freed from cumulus cells and then cultured in vitro with BSA alone, little reduction of zona hardening was observed. Preincubation of CEOs for 5h with fetuin, one of the well known inhibitor of in vitro zone hardening, did not prevent bona hardening during its subsequent culture of CEOs for 14h without fetuin. However, when CEOs precultured with both fetuin and PMSG for 5h and then further cultured with BSA alone for 14h, zona hardening was dramatically reduced. Under these conditions, the expansion of cumulus cell was observed. In addition, CEOs cultured with both BSA and dbcAMP to prevent their meiotic resumption showed a significant increase of zona hardening. Whether the observed zona hardening was correlated with the conversion of ZP2 to ZP2f was examined. Zona pellucida, isolated from CEOs matured for 5h in vivo and then further cultured with BSA alone was subjected to SDS-PAGE. Most of ZP2 molecules from these CEOs did not undergo conversion from ZP2 to ZP2f. From these results, it is concluded that CEOs undergone meiotic resumption in vivo do not exhibit bona hardening when they were subsequently cultured in vitro without serum components. It appears that cumulus cells play an important role in this phenomenon.

OBJECTIVES: This study aimed to find gender distinctions in terms of the sociology of the population; to determine work-related factors; to analyze gender differences in daily living, work, sports, and art performances; and to identify gender-related factors that limited performance of daily living and work activities. METHODS: A questionnaire was designed that included disabilities of the arm, shoulder, and hand (DASH), accident history, disease history, work duration at current workplace, marital status, job satisfaction, job autonomy, and physical demands of the job. Out of 1,853 workers surveyed, 1,173 questionnaires (63.3%; 987 males, 186 females) included responses to DASH disability and DASH optional work and were judged acceptable for analysis. RESULTS: Upper extremity functional limitation during work and daily living was higher for females than males. The limitations for males increased according to their household work time, accident history, work duration, job satisfaction, physical demand, and job autonomy. Meanwhile, female workers' upper extremity discomfort was influenced by their disease history, job satisfaction, and physical demands. In addition, the size of the company affected male workers' upper extremity function, while marriage and hobbies influenced that of female workers. CONCLUSION: This study addressed sociodemographic factors and work-related factors that affect each gender's upper extremity function during daily living and working activities. Each factor had a different influence. Further studies are needed to identify the effect that role changes, not being influenced by risks at work, have on musculoskeletal disorders.

OBJECTIVES: Discomfort in the upper extremities affects and restricts the daily activities and work of many workers. This study was conducted to apply a standardized tool for identifying musculoskeletal symptoms and measuring how greatly these symptoms affect the performance of workers in small manufacturing industries as well as to analyze the relationships between the socio-demographic characteristics of the workers, the psychosocial factors, and ergonomic risk factors on the one hand and the reported musculoskeletal symptoms and their effects on work performance on the other. METHODS: Workers in small manufacturing companies were asked to self-evaluate musculoskeletal symptoms, restrictions on work performance, and the ergonomic risk in their working environments. A standardized tool (musculoskeletal symptoms table, DASH [Disability of the arm, shoulder, and hand]) was used to evaluate the musculoskeletal symptoms and the restrictions on work performance. RESULTS: 1) The DASH score was significantly higher among women, older workers who had been in that job for a long time, married workers, those with no leisure activities or hobbies, those with long hours of housework, those who had experienced a disease in the past, and those who had had an accident in the past; 2) the DASH score was also significantly higher for those workers who were unsatisfied with their work, who worked hard, who no control over their work, and whose work required heavy equipment, tools, and materials; 3) the DASH score was significantly higher in workers with major ergonomic risk factors; 4) the DASH score was significantly higher among workers with occupational musculoskeletal disease and was distributed as follows, from highest to lowest rates of occurrence; symptoms in the upper arms, difficulty sleeping, difficulty with work, restrictions in daily activities, restrictions in social activities, and difficulties in specific work performance; 5) explanatory power increased in the model with the addition of socio-demographic variables, i.e., in analyses with the DASH total score as the dependent variable and psychosocial factors, ergonomic risk factors, and upper extremity discomfort symptoms as the independent variables. The total explanatory power found a significant effect at 35.3%. CONCLUSIONS: The results of this study show that to enhance the upper extremity performance level of workers in the manufacturing industry, preventive measures should be based on a consideration of ergonomic risk factors, psychosocial factors, and the socio-demographic characterisitics of the individual workers.
