Ial indicate that Na+, K+-ATPase activity and total protein content in the leaded or unleaded gasoline groups were lower than those of the control group. The inhibition of the plasma membrane Na+, K+-ATPase might have been attributed to a direct effect of the solvents and alcohols in the gasoline on the membrane causing dissolving the its bilayers. The most outstanding are toluene (highly lipophyl

Between the groups inhaled the leaded gasoline and the control. The GSH content was lower in both the leaded and unleaded gasoline groups than the control group, but GSH in the unleaded group was higher than in the leaded group. The unleaded gasoline exposed group exhibited a significant decrease in superoxide dismutase activity in comparison with either the leaded gasoline or the control groups.

Ecules or to relative reduction in acetylcholinesterase-containing neurons, thus potentiating cholinergic effects. In the present study, no statistical differences were detected among the serotonin levels of the cerebral cortex in the three groups; the control, the leaded and the unleaded. However, in the hypothalamus, hippocampus, cerebellum, the serotonin level was lower in the groups exposed to

Is the study of Gutteridge and Halliwell [44] showing that Na+, K+-ATPase reduces its activity up to 50 due to oxidative stress. The present findings show that the rats exhibited a decrease in the activity of AChE in the unleaded group in comparison with either the control or the leaded groups. In addition to its function in degrading acetylcholine and modulation of neural function; AChE as a str
