چکیده انگلیسی
Toluene is the main component of a variety of inhalants that are used for intoxication purposes. Alterations in memory have been reported in inhalant users; however, it is unclear whether these impairments could be reversed, and the mechanisms involved in the putative recovery. Therefore, the main purpose of this study was to model the deleterious effects of toluene on memory in mice and to evaluate the effect of environmental enrichment on that response. In the second part of the study, the concentrations of glutamate and GABA, following chronic toluene exposure and after environmental enrichment treatment, were evaluated. Adolescent mice were exposed to either a single or repeated schedule of toluene administration and their responses to object recognition were analyzed. An independent group of mice was repeatedly exposed to toluene and then housed either under environmental enrichment or standard conditions for four weeks. At the end of the housing period, the rodents' performance in object recognition test, as well as the concentrations of neurotransmitters, were analyzed. The results showed that toluene caused memory impairment in mice that received a single or repeated solvent exposure. Remarkably, environmental enrichment could reverse memory deficits induced by repeated administration of toluene. Cessation of toluene exposure in mice in standard housing did not produce that response. The glutamate and GABA tissue contents were not involved in the effects of toluene or environmental enrichment of memory.
