Nd norepinephrine were elevated above the control level. Data in table 5 reveal that Na+, K+-ATPase activity and total protein content in the two groups exposed to gasoline were lower than the control, although no significant difference was found between each other. The rats exposed to the unleaded gasoline had a significantly lower acetylcholinesterase activity as compared with the control or lea

Nnervations reaches out to the hypothalamus to regulate secretion of TRH and prolactin secretion, and then projects to the brain limbic system to modulate motivations and emotions [47]. So, gasoline induced impairment of the DA system would result in serious impacts on the neural control of voluntary locomotion and would affect several behavioural aspects.In the present study, the norepinephrine l

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
