RESUMEN
Petrol vapors as important occupational and environmental pollutants can cause oxidative stress and may play a role in the development of neurodegenerative diseases along with the risk factors involved. This research is designed as a preliminary study to evaluate the protective effects of apigenin (APG) on oxidative stress caused by petrol vapors inhalation in rats. A total of 24 male Wistar rats were randomly divided into four groups inside the inhalation chamber. Body weight changes and oxidative stress markers were investigated. The average body weight of the group exposed to petrol vapors was significantly lower compared to the other groups. The level of reactive oxygen species (ROS), content of oxidized-glutathione (GSSG), and Malondialdehyde were found to be higher in the petrol-inhaled group, while the content of reduced-glutathione (GSH) was lower compared to the other groups. APG administration did result in any significant improvement in these toxicities induced by petrol vapor. APG administration may ameliorate the petrol-induced oxidative stress. In chronic exposures, in addition to personal protection and engineering control, the use of compounds of natural origin may help in reducing the side effects (such as CNS) caused by exposure to petrol vapors.
