ABSTRACT
Purpose:
To examine thiol-disulphide homeostasis auto painters.Materials andmethods:
A total of 115 male workers, including 60 auto painters workers and 55 reference group, of the painting and assembly line units respectively, were included in the study. Thiol-disulphide parameters and ischaemia-modified albumin (IMA) of groups were determined. Urinary hippuric acid, (HA) phenol, hexanedione, trichloroacetic acid, arsenic and blood lead and manganese were analysed.Results:
The median urinary HA level was significantly higher in auto painters when compared to the reference group [(2461 (1212) vs. 520 (513) µgr/L), (p < 0.001)] . The mean disulphide level [19.7 (4.3) vs 0.15.1(4.1) µmol/L, (p < 0.001)], the disulphide/native thiol ratio [4.72 (1.47) vs. 3.13 (1.21, (p < 0.001)] and the disulphide/total thiol ratio [4.31 (1.23) vs. 2.94 (1.06), (p < 0.001)] were higher in auto painters when compared to the reference group. There was a statistically significant positive correlation between urinary HA and disulphide concentrations (r = 0.536 and p < 0.001), disulphide/native thiol ratio (r = 0.564 and p < 0.001) and the disulphide/total thiol ratio (r = 0.564 and p < 0.001) and IMA (r = 0.396 and p < 0.001).Conclusion:
The results presented in this study showed that oxidative stress can be associated with occupational exposure to toluene denoted by alteration of thiol disulphide homeostasis and ischaemia-modified albumin levels.Key words
