Immunologic findings in workers formerly exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin and its congeners
One hundred ninety-two workers in a German pesticide factory who were exposed to polychlorinated dibenzodioxins and -furans (PCDD/PCDF) were investigated for former and present diseases and laboratory changes of the immune system. Moreover, in a subgroup of 29 highly exposed and 28 control persons, proliferation studies were performed. In addition to assays such as blood count, immunoglobulins, serum electrophoresis, monoclonal bands, surface markers, autoantibodies, and lymphocyte proliferation, two new methods, the rise of tetanus antibody concentration after vaccination and the in vitro resistance of lymphocytes to chromate, were used to diagnose the morphologic and functional state of t…
No influence of magnetic fields on cell cycle progression using conditions relevant for patients during MRI.
The purpose of this study was to examine whether exposure to magnetic fields (MFs) relevant for magnetic resonance imaging (MRI) in clinical routine influences cell cycle progression in two tumor cell lines in vitro. HL60 and EA2 cells were exposed to four types of MFs: (i) static MF of 1.5 and 7.05 T, (ii) extremely low frequency magnetic gradient fields (ELFMGFs) with ± 10 mT/m and 100 Hz, as well as ± 100 mT/m and 100 Hz, (iii) pulsed high frequency MF in the radiofrequency (RF) range (63.6 MHz, 5.8 μT), and (iv) a combination of (i–iii). Exposure periods ranged from 1 to 24 h. Cell cycle distribution (G0/G1, S, and G2/M phases) was analyzed by flow cytometry. Cell cycle analysis did not…
P165 Workplace and commuting accidents of german teachers: an analysis of accident reports
Introduction Since 2011 the Institute for Teachers’ Health (IfL) is responsible for the occupational health of more than 40.000 German teachers. Analysing teachers’ accidents is an important part of everyday work. The aim of the study was to describe accident black spots and type of injuries. We further wanted to identify factors influencing accident severity. Methods We included accident reports of teachers between August 2011 and July 2014 (three school-years) which occurred at schools in Rhineland-Palatinate (Germany). In case of an accident, teachers fill out an accident report which is forwarded either to the statutory accident insurance or to the IfL. For the present analysis, anonymi…
