مستخلص: | Occupational exposure to organic solvents present in paints is responsible for an increased production of reactive species, thus enabling the development of several diseases. Besides, both exo- and endogenous antioxidant defense systems are necessary to avoid oxidative tissue damage. This study investigated possible protective effects of the exo- and endogenous antioxidants on oxidative damage in painters occupationally exposed to organic solvents (n = 42) and controls (n = 28). Retinol, lycopene and β-carotene were significantly lower in the exposed group. Despite the fact that blood toluene was below the biological exposure limits, malondialdehyde levels and antioxidant enzyme activities were increased, whereas reduced glutathione levels were decreased in painters, compared to nonexposed subjects. Moreover, multivariate regression models showed that reduced glutathione and carotenoids (mainly β-carotene) have the major influence on lipid peroxidation (LPO). The present work suggests that the exogenous antioxidants, such as carotenoids, could protect occupationally exposed subjects to xenobiotics from LPO. |
