1. Physiopathological aspects of NMDA transmission in the basal ganglia : in vitro and in vivo release studies
Sammanfattning : N-methyl-D-aspartic acid (NMDA) is an excitatory amino acid selectively acting on a subclass of glutamate receptors (the NMDA ionotropic receptor) which has been involved in many of the physiological and pathological effects of glutamate in the CNS. The basal ganglia are particularly enriched in NMDA receptors and NMDA receptor activation in the basal ganglia has been involved in the expression of motor behaviour. LÄS MER
2. Development of in vitro and ex vivo positron-emitting tracer techniques and their application to neurotrauma
Sammanfattning : The use of positron-emitting tracers has been extended beyond tomographic facilities in the last few years, giving rise to a general positron-emitting tracing technique. The methodological part of the present thesis involved the evaluation of the performance of storage phosphor (SP) plates, with tracers labeled with high-energy, short-lived, positron-emitting radionuclides, using homogenized tissue specimens and autoradiography with frozen brain sections.

3. Comparative genome and proteome analysis of brain tissue from MK-801-treated rats
Sammanfattning : Symptoms of intoxication with non-competitive N-methyl-D-aspartate (NMDA)-receptor antagonists, closely mimic symptoms in patients with schizophrenia, and therefore [+]-5-methyl-10,11-dihydro-5H-dibenzo-[a,d]-cycloheptene-5,10-iminehydrogen-maleate (MK-801, dizocilpine) treated rodents are often used as a model for schizophrenia. To investigate if administration of the NMDA receptor antagonist MK-801 to rats would induce messenger ribonucleic acid (mRNA) or protein disturbances mimicking those observed in schizophrenic patients, complementary deoxyribonucleic acid (cDNA) microarrays and two-dimensional gel-electrophoresis in combination with mass spectrometry were used, respectively.

4. The phencyclidine model of schizophrenia : dysregulation of brain dopamine systems induced by NMDA receptor antagonists
Sammanfattning : Non-competitive NMDA receptor antagonists, such as phencyclidine (PCP) and dizocilpine (MK-801) can even acutely induce a drug induced psychotic state which closely resembles schizophrenia. The midbrain dopamine (DA) neurons, which originate in the ventral tegmental area (VTA), are involved in motivational, attentional and cognitive processes, and have also been profoundly implicated in schizophrenia.

5. Ischemic brain damage following transient and moderate compression of sensorimotor cortex in Sprague-Dawley and diabetic Goto-Kakizaki rats
Sammanfattning : Several animal models have been developed to facilitate the investigation of biochemical, physiological, and neurological events after cerebral ischemia. In this study we present a new animal model which reliably describes morphological changes and neurological deficits produced by mild to moderate brain ischemia and which can be used to identify novel, potentially useful, neuroprotective agents.
