Alzheimer's disease is a neurodegenerative disorder with the highest prevalence in the population and for which we do not have a cure so far. The aim of this thesis was to test the mediator system of the N-methyl-D-aspartate receptor and nitric oxide in an animal model of sporadic form of Alzheimer's disease (Samaritan Alzheimer's Rat Model; Taconic Pharmaceuticals, USA). Then compare these results with changes in hippocampal cholinergic system and cognitive tests. The Samaritan rat model is based on the unilateral in vivo application of β-amyloid42 and the pro-oxidative substances (ferrous sulfate heptahydrate and L-buthionine-(S,R)-sulfoximine). Neurochemical methods included testing of the NR1/NR2A/NR2B subunits of the N-methyl-D-aspartate receptor and activity of nitric oxide synthases (neuronal, endothelial, inducible) in the cortex, in both cases in the right and left hemisphere separately. Our results show that Samaritan rats exhibited significant changes in expression of NR2A/NR2B subunits of the N-methyl-D-aspartate receptor and activity of inducible nitric oxide synthase in cortex compared to control rats. The results of glutamatergic system are consistent with changes in activity of cholinergic transporter and cognitive tests (Morris water maze and active allothetic place avoidance)....

The role of nitric oxide in the patophysiology of neurodegenerative diseases
Matušková, Hana ; Otáhal, Jakub (advisor) ; Alánová, Petra (referee)
The bachelor thesis deals with the importance of nitric oxide in the development of neurodegenerative diseases. Nitric oxide is a biological active gas which affects, among other things, many functions of the central nervous system. Its activity is dependent on the concentration in small amounts has a positive effect, while overproduction contributes significantly to the development of neurodegenerative diseases. In my work, I deal with the negative influence of nitric oxide in the development of epileptic seizures, Parkinson's disease, Alzheimer's disease and Huntington's disease. In conclusion, I mentioned the possibility of determining the amount of nitric oxide concentration.
