Abstract

|
|
|
Male Sprague-Dawley rats were exposed to the toluene at 3,000+/-200ppm via inhalation for two hours (single inhalation group), three weeks by two hours per day, six days per wee k (repeated inhalation group). We examined the level of excitatory amino acids of the extracellular neurotransmitter within the corpus striatum of rats by using in vivo microdialysis. Aspartate (Asp) and glutamate (Glu) of excitatory amino acid neurotransmitters were generally decreased in the inhalation groups compared with the control group, and more significantly decreased in the repeated inhalation group than in the single inhalation group except that Asp was increased from 60 min after the beginning of the inhalation to 30 min after the termination.
