Dopamine release and metabolism in awake rats after systemic neuroleptics as studied by trans-striatal dialysis.
The method of trans-striatal dialysis has been applied here to the study of the release and metabolism of dopamine (DA) in the awake rat. DA and its acidic metabolites, dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA), present in the dialysates were separated by high performance liquid chromatography on reverse phase columns and estimated by electrochemical detection. In the awake...
متن کاملDopamine depletion in neonatal rats: effects on behavior and striatal dopamine release assessed by intracerebral microdialysis during adulthood.
Rats depleted of dopamine (DA) by intraventricular 6-hydroxydopamine (6-OHDA) in infancy show behavioral impairments as adults, but their basic sensory-motor functions and feeding abilities are intact; at least relative to the pronounced deficits seen in rats given similar treatment in adulthood. Here we investigate whether presynaptic changes culminating in enhanced DA release are present in a...
متن کاملCharacterization of dopamine release in the substantia nigra by in vivo microdialysis in freely moving rats.
Dopamine (DA) is released not only from the terminals of the nigrostriatal projection, but also from the dendrites of these neurons, which arborize in the substantia nigra pars reticulata (SNR). Although striatal DA release has been extensively studied by in vivo microdialysis, dendritic DA release in the SNR has not been characterized by this technique. Extracellular DA was monitored simultane...
متن کاملComparative effects of organic and inorganic mercury on in vivo dopamine release in freely moving rats.
The present study was carried out in order to compare the effects of administration of organic (methylmercury, MeHg) and inorganic (mercury chloride, HgCl 2 ) forms of mercury on in vivo dopamine (DA) release from rat striatum. Experiments were performed in conscious and freely moving female adult Sprague-Dawley (230-280 g) rats using brain microdialysis coupled to HPLC with electrochemical det...
متن کاملComparative effects of pesticides on in vivo dopamine release in freely moving rats.
The effects of different types of pesticides on the in vivo striatal dopamine release were investigated by using in vivo brain microdialysis technique. MPTP, paraquat, maneb, dicofol, DDT, lindane and flutriafol (1 mM) were administered directly into the striatum, and levels of dopamine and its metabolites dihydroxyphenylacetic acid (DOPAC) and homovallinic acid (HVA) were measured using HPLC-E...
