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: We report on a case-study of a silicosis sufferer with lung cancer, who was exposed to cement dust through plastering and waterproof work in the construction industry. METHODS: We reviewed his personal history including employment, medical record and estimated level of carcinogenic materials in the work place in order to evaluate the possible source of his lung cancer. RESULTS: The patient was a non-smoker and there was no family history of lung cancer. His medical record did not reveal anything of concern. He was exposed to cement dust while he had worked for 20 years as a plasterer and waterproof worker. After complaining of chest pain, he was examined and subsequently diagnosed with lung cancer (RUL, adenocarcinoma; cT4N2M1). He was treated in a hospital for 3 months before passing away. Radiological evaluation by high resolution computed tomography (HRCT) revealed micronodules with a profusion category 1 (p/p, 1/1) in the perilymphatic distribution, which indicated silicosis. Small amounts of cement dust which included silica was identified by environmental evaluation of his work place. He never worked with asbestos related material, which was confirmed by HRCT examination. CONCLUSIONS: We concluded that the patient's silicosis with lung cancer was an occupational-caused disease due to exposure to cement dust.

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.

PURPOSE: To evaluate the specif!c radiologic findings of the dysgenesis of corpus callosum(CCD) on CT and/or MR images. MATERIALS AND METHODS: The authors reviewed retrospectively CT and/or MR images of 10 patients with CCD. After classifying CCD into partial and total type according to the degree of its development, we investigated structural abnormalities on CT and/or MR images resulting from or related to CCD and then associated anomaly. RESULTS: The most common findings of CCD on axial planes of CT and/or MR images were dilatation of posterior part of the lateral ventricles(8/10) and feature of the bodies of the both lateral ventricles(8/10) in parallel. Sagittal and coronal planes of MR demonstrated exact extent of dysgenesis of the corpus callosum(5/5) and radiating pattern of gyri in medial surface of cerebral hemisphere extending to the 3rd ventricle without interruption by cingulate sulcus(4/5). CONCLUSION:MR image of mid-sagittal plane appeared most useful in diagnosis of CCD because of its direct depiction of the whole length of corpus callosum. In most cases, however, CCD can be easily diagnosed with CT scan by characteristic findings of dilatation of the posterior part of lateral ventricles and paralleling of the lateral ventricles.
