BACKGROUND: Shipbuilding involves intensive welding activities, and welders are exposed to a variety of metal fumes, including manganese, that may be associated with neurological impairments. This study aimed to characterize total and size-fractionated manganese exposure resulting from welding operations in shipbuilding work areas. METHODS: In this study, we characterized manganese-containing particulates with an emphasis on total mass (n = 86, closed-face 37-mm cassette samplers) and particle size-selective mass concentrations (n = 86, 8-stage cascade impactor samplers), particle size distributions, and a comparison of exposure levels determined using personal cassette and impactor samplers. RESULTS: Our results suggest that 67.4% of all samples were above the current American Conference of Governmental Industrial Hygienists manganese threshold limit value of 100 μg/m3 as inhalable mass. Furthermore, most of the particles containing manganese in the welding process were of the size of respirable particulates, and 90.7% of all samples exceeded the American Conference of Governmental Industrial Hygienists threshold limit value of 20 μg/m3 for respirable manganese. CONCLUSION: The concentrations measured with the two sampler types (cassette: total mass; impactor: inhalable mass) were significantly correlated (r = 0.964, p < 0.001), but the total concentration obtained using cassette samplers was lower than the inhalable concentration of impactor samplers.

Wrestlers has frequently injured on his ear by friction or hitting. If the ear injury like hematoma did not treat appropriately, it should be deform to disfigured outer shape. We analyzed the incidence and characteristics of ear deformity with elite wrestlers. We took the photo with elite 58 male wrestlers' ears. We surveyed the carrier of elite player, duration of training time, ear injury history, treatment history and satisfactory scale of his ear shape. The characteristics of ear shape were classified by Yotuyanagi classification. 44 wrestlers has deformity of his ear in elite wrestlers (76%, 44/58). Right side ear deformity is 50 cases, bilaterally involvement is one case. Microtia was 11 (24%), ear protrusion was 15 (33%) cases. Yotuyanagi type IB was 13 (29%) cases that deformity extending from helix to antihelix. Type IIA was 12 (27%) cases that deformity with a substantial change with good structural integrity in outline of the ear. Acute ear injury was treated with simple icing (33 cases, 56%), aspiration and compression (6 cases, 10%). 34 wrestlers (77%) dissatisfied his own ear shape. 10% of acute ear injuries treat appropriately in domestic elite male wrestlers. 76% of the wrestlers has an ear deformity and dissatisfaction.

BACKGROUND: There is a clinical need for a simpler measurement of global cardiac function incorporating elements of both systole and diastole. Doppler time index is theoretically regarded as a sensitive index of global left ventricular perfomance and defined as the sum of isovolumetric contraction time (IVCT) and isovolumetric relaxation time (IVRT) divided by ejection time (ET). This study was designed to determine the clinical usefulness of the Doppler time index in patients with left ventricular diastolic dysfunction as well as systolic dysfunction. METHODS: The study population consisted of 23 patients with hypertension as a diastolic dysfunction group, 16 patients with low ejection fraction as a systolic dysfunction group and 31 subjects with normal LV function. The ejection fraction (EF) was measured using M-mode echocardiography. Doppler profiles such as IVCT, IVRT and ET were obtained from Doppler echocardiography. The Doppler time index [ (IVCT+RT)/ET] was calculated from each Doppler velocity profiles. RESULTS: IVRT, IVRT/ET and (IVCT+VRT)/ET were significantly increased in the diastolic dysfunction group (120.5+/-19.5 msec, 0.45+/-0.1, 0.64+/-0.2, respectively:p<0.001, p<0.001, p<0.001, respectively) compared with normal subjects (66.1+/-17.4 msec, 0.25+/-0.0, 0.41+/-0.1). IVCT and IVRT were significantly increased and ET was significantly shortened in systolic dysfunction group (75.4+/-25.7, 144.0+/-39.5 msec, 242.7+/-46.5 msec respectively:p<0.001, p<0.05, p<0.05, respectively) compared with diastolic dysfunction group (50.4+/-23.0 msec, 120.5+/-19.5 msec, 276.8+/-44.6 msec, respectively). IVCT/ET, IVRT/ET and (IVCT+IVRT)/ET also were increased in patients with systolic dysfunction group (0.32+/-0.1, 0.61+/-0.2, 0.93+/-0.2 respectively:p<0.01, p<0.01, p<0.001, res-pectively) compared with diastolic dysfunction group (0.19+/-0.1, 0.45+/-0.1, 0.64+/-0.2). Ejection fraction calculated by M-mode parameters was significantly correlated with (IVCT+IVRT)/ET (correlation coefficient - 0.605, p<0.001). CONCLUSION: The Doppler time index was significantly difficient from normal subjects in patients with isolated LV diastolic dysfunction as well as in those with systolic dysfunction. Thus, this index can be used as a sensitive indicator of myocardial performance.

BACKGROUND AND OBJECTIVES: For the treatment of nasopharyngeal carcinoma (NPC), radiation therapy is a primary option. Because of distant metastasis and the high incidence of a locoregional failure following radiotherapy, the combined treatment modality with chemotherapy is applied, although resistance to chemotherapy makes chemotherapy less effective. The Cisplatin-based chemotherapy has been widely used in the field of nasopharyngeal cancer. The Cisplatin resistance is known to be caused by the multidrug resistance-associated protein (MRP), which is one of the drug-export pumps and the glutathione S-transferase (GST)-pi which catalyzes the conjugation of the GSH (glutathione) and the cisplatin. The aim of this study is to determine the predictive value of GST-pi and MRP upon the response to cisplatin in nasopharyngeal carcinoma. SUBJECTS AND METHOD: We analyzed tumor tissues from 49 cases of paraffin block specimens which were diagnosed with NPC and treated at Chonnam National University Hospital. The immunohistochemical study for the GST-pi and the MRP was performed with paraffin block specimens of nasopharyngeal cancers. RESULTS: In the GST-pi, the relationship between the early stage (64.3%) and the advanced stage (91.4%) was statistically significant (p=0.020). The expression of the GST-pi and the MRP had no relationship with the clinical factor, the response to chemotherpy and the survival rate. CONCLUSION: Because the expression of the GST-pi and the MRP in the nasopharyngeal carcinoma could not predict the response to chemotherapy. So the efforts to find the predictive value of the chemotherapy are needed.

PURPOSE: This study was performed to evaluate the characteristics of rat mesenchymal stem cells (RMSCs) transduced with human ferritin gene and investigate in vitro MRI detectability of ferritin-transduced RMSCs. MATERIALS AND METHODS: The RMSCs expressing both myc-tagged human ferritin heavy chain subunit (myc-FTH) and green fluorescence protein (GFP) were transduced with lentiviurs. Transduced cells were sorted by GFP expression using a fluorescence-activated cell sorter. Myc-FTH and GFP expression in transduced cells were detected by immunofluorescence staining. The cell proliferative ability and viability were assessed by MTT assay. The RMSC surface markers (CD29+/CD45-) were analyzed by flow cytometry. The intracellular iron amount was measured spectrophotometically and the presence of ferritin-iron accumulation was detected by Prussian blue staining. In vitro magnetic resonance imaging (MRI) study of cell phantoms was done on 9.4 T MR scanner to evaluate the feasibility of imaging the ferritin-transduced RMSCs. RESULTS: The myc-FTH and GFP genes were stably transduced into RMSCs. No significant differences were observed in terms of biologic properties in transduced RMSCs compared with non-transduced RMSCs. Ferritin-transduced RMSCs exhibited increased iron accumulation ability and showed significantly lower T2 relaxation time than non-transduced RMSCs. CONCLUSION: Ferritin gene as MR reporter gene could be used for non-invasive tracking and visualization of therapeutic mesenchymal stem cells by MRI.
