Effects of memantine and riluzole on learning deficits in an animal model of obsessive-compulsive disorder induced by 8-OH-DPAT sensitization
Mainerová, Karolína ; Stuchlík, Aleš (advisor) ; Kelemen, Eduard (referee)
Obsessive-compulsive disorder is a chronic psychiatric disease. It seriously limits the quality of life of patients. Treatment of OCD is not yet fully successful and still many patients are left with debilitating symptoms without functioning medication. Animal models of genetic, behavioral, pharmacological, and optogenetic origins are beneficial in the achievement of new understandings of the disease. Chronic sensitization of serotonin 1A and 7-receptors with an agonist 8-OH-DPAT ((8- hydroxy-2-(di-propylamino)-tetralin hydrobromide) induces perseverative and compulsive behaviors, which is considered to constitute an animal model of OCD. In this thesis, the 8-OH- DPAT model has been tested in the active place avoidance task on Carousel maze to provide information about the model on learning. Second, this model is used to determine, whether co- administration of memantine or riluzole alleviates the cognitive and learning deficits of this model. To uncover these effects, an active place avoidance task on a Carousel maze was used. Measured criteria were total distance, entrances to the shock sector, total number of shocks, and median speed after the shock. During habituation, the animals were sensitized to 8-OH-DPAT (with a control group that did not receive 8-OH-DPAT but only saline). In an...
