    This study is aimed to evaluate the incidence of silicosis and the relation of it with personal and work-related factors among workers exposed to silica in ceramic factory. Workers were evaluated by respiratory symptoms, physical examination, pulmonary function and radiological findings. Occupational and Enviromental Pulmonary Disease Evaluation Questionnaire of the Turkish Thoracic Society Enviromental and Occupational Pulmonary Diseases Working Group was used. 365 of 626 workers had exposure to silica and the rest 261 were concerned as control group. There was no difference between mean age, duration of work and smoking pack year among the groups (p> 0.05). Cough and sputum rates were higher in silicosis group FEV1 and FVC values were lower in silica group but this was not statistically significant. When the two subgro-ups of silica group (the workers in high dust concentration and the ones in low concentration) were compared, the high concentrated group had significantly more sputum but the other symptoms and pulmonary functional parameters were not different significantly. 24 workers had parenchymal densities adjusted with pneumoconiosis. The workers with the pneumoconistic finding, had a higher mean age and longer duration of work. As a conclusion, ceramic industry has risk for silicosis. And the risk increase by time and age.

    Effect of severity of asthma on quality of life
    Sakar, A; Yorgancioglu, A; Aydemir, O; Sepit, L; Çelik, P
    This study is aimed to evaluate the health related quality of life (HRQL) in asthmatics and the probable association between HRQL and disease severity and also other demographic factors by using a generic scale, SF-36 questionnaire. One-hundred and two asthmatics were enrolled. The scores of the 8 domains of SF-36 questionnaire were evaluated according to age, gender, status of education and compared with the severity of asthma. The mean age of 84 (83%) female and 18 (17%) male patients was 42.86 +/- 11.15. Fifty-two of them was well educated (51%) and 50 was poorly educated (49%). Atopy ratio was 81%. Mild intermittent, mild persistent and moderate-severe persistent groups were 27 (26%), 46 (45%) and 29 (29%) respectively. Female gender were worse in physical functioning (p= 0.000), physical role difficulties (p= 0.0049), vitality (p= 0.045) and social functioning (p= 0.025). Poorly educated group were worse in physical functioning (p= 0.001), physical role difficulties (p= 0.039), vitality (p= 0.045), emotional role difficulties (p= 0.046), general health (p= 0.030) and mental health (p= 0.044). Mental health was worse in the presence of atopy (p= 0.035). Physical functioning was better in mild intermittent group than moderate and severe persistent group (p= 0.024). General health was better in mild intermittent group than mild persistent group (p= 0.018), moderate and severe persistent group (p= 0.015). Vitality and emotional role difficulties was better in mild intermittent than mild persistent group (p= 0.042, p= 0.007). The HRQL scores and severity of asthma is well correlated like other objective parameters. So one of the primary goals in management of asthma should also improve QOL as well as functional parameters.

    Effect of recombinant human activated protein C on apoptosis-related proteins
    Sakar, A; Vatansever, S; Sepit, L; Ozbilgin, K; Yorgancioglu, A
    The recombinant human activated protein C (rhAPC) has been reported to reduce mortality in patients with severe sepsis. An anti-apoptotic effect of rhAPC in sepsis is known, but the mechanism through which it acts on the apoptotic pathway is still unclear. Therefore, immunopositivity of the apoptosis-related proteins Bcl-2, an anti-apoptotic protein, c-myc, a proliferative protein, p-21 and p-53, two apoptotic proteins, was determined after rhAPC treatment in a mouse sepsis model. Sepsis was induced by Escherichia coli endotoxin injection. Increased neutrophil infiltration and immunoreactivity to p53 and p2l were observed in the group with sepsis and these immunoreactivities were decreased by rhAPC treatment. In the sepstic group; immunopositivity of Bcl-2 and c-myc was mild and moderate, respectively. In conclusion; p21- and p53-mediated apoptosis was increased in the sepsis model, and for the first time it has been shown that rhAPC decreases sepsis-induced apoptosis resulting from increased p2l and p53 proteins.
