Fig. 1

Levels of biomarkers of oxidative stress in nail technicians (solid line, ■) and control subjects (dashed line, ○) during the “hot” and “cold” season. Individual panels show data for the plasma levels of TBARS (a), the activity of GPx3 (b), the activity of GPx1 (c), the plasma level of Cp (d), the activity of SOD1 (e) and the SOD1/GPx1 activity ratio (f). All data are presented as ln-transformed means (central points) ± SD (error bars). Natural-base logarithm transformation was employed in order to normalize the distribution of raw data for the purpose of MANCOVA analysis. Asterisks indicate the respective levels of significance of inter-season differences observed among nail technicians and/or control subjects. The activity of SOD1 (panel e) was found to be significantly affected by the interaction between the season and the group of given individual (p < 0.05) although no significant inter-seasonal differences were found * p < 0.05; ** p < 0.0005; *** p < < 0.0001
