ABSTRACTIntroduction. Alcoholism is a chronic disease produced by the uncontrolled consumption of alcoholic beverages. Alcohol Abstinence Syndrome (AAS) is the clinical expression of the abrupt interruption or decrease of alcohol intake in a patient who has developed physical dependence. During AAS, neuronal imbalance occurs between the neurotransmitters GABA and glutamate that trigger an increase in Reactive Oxygen Species associated with important behavioral disorders. On the other hand, the metabolism of ethanol itself generates the formation of Acetaldehyde, a highly toxic metabolite capable of generating oxidative stress by different mechanisms, under these conditions the activity of the cerebral mitochondrial Aldehyde Dehydrogenase (ALDH) enzyme is inhibited, which leads to the accumulation of Acetaldehyde and other toxic aldehydes such as Malonyldialdehyde and 3,4 dihydroxyphenylacetaldehyde.
Objective. To determine the actions of medical ozone on GABA, Glutamate and cerebral aldehyde dehydrogenase 2 in alcoholic rats during abstinence.
Materials and methods. In the model of alcoholism developed in Lewis rats, medical ozone (1mg / kg rectally, 10 sessions, every 24 hours) was applied during the abstinence stage.
Results. The activity of the ALDH enzyme was preserved and restored the redox balance at the cerebral level. These results corresponded to a decrease in behavioral disorders related to neuronal imbalance.
Conclusions. Pharmacological manipulation of the Gabaergic and glutamatergic receptors showed that even under conditions of neuronal imbalance reinforced by agonists and / or antagonists of these receptors, medical ozone decreased pro-oxidant / antioxidant imbalance and related behavioral disorders (anxiety).
