The effect of classical conditioning with d-amphetamine on the extracellular concentrations of dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in the striatum of awake, freely moving rats was studied using microdialysis. This was done in order to test, whether there occurred alterations in DA release as conditioned(More)
The present experiments were performed in order to investigate the effects of dopamine(DA)ergic drugs on the concentrations of extracellular glutamate (GLU) in the striatum of non-anaesthetised, freely moving rats by using microdialysis and to get further information about the interactions between glutamatergic and dopaminergic pathways. GLU was determined(More)
BACKGROUND Over the last few years, differential ion mobility spectroscopy (DMS) has become an important tool in medical research. There are attempts to find markers for specific diseases in exhaled air, using this technology as a non-invasive early diagnosis. OBJECTIVE In the present research, exhaled air from 78 patients with known diagnosis and 39(More)
The extracellular concentrations of glutamate (GLU) or gamma-aminobutyric acid (GABA) in the striatum were determined in non-anesthetized, non-restrained rats using the microdialysis method, and the effects of some dopaminergic drugs were studied. Since a great part of these amino acids in the extracellular space is probably of origin not related to(More)
