It has been proposed that molecules derived from reactions that occur between the ozone and the lung tissue mediate nonpulmonary effects caused by ozone exposure. Free radicals are among those proposed molecules that flow throughout the bloodstream to other organs producing lipid peroxidation. In order to elucidate on aspect of ozone toxicity mechanisms, we measured the thiobarbituric acid-reactive...
We have shown in our laboratory that cat's and rat's sleep disturbances are produced by 24 h of ozone (O3) exposure, indicating that the central nervous system is affected by this gas. To demonstrate the probable changes in brain neurotransmitters, we evaluated the monoamine contents of the midbrain and striatum of rats exposed to 1 part per million O3 for 1 or 3 hours periods. The results were compared...
