Μελέτη της επίδρασης του βαλπροϊκού νατρίου στη διεργασία της ήβης, στη συμπεριφορά ενεργητικής αποφυγής και στις βιολογικές αμίνες του εγκεφάλου, υπό χρόνια και οξεία χορήγηση και από επίδραση stress: Πειραματική εργασία σε επίμυες
… stress. The brain neurotransmitters NA, DA, DOPAC, (DOPAC/DA), 5-HT, 5HIAA, (5HIAA/5-HT) were measured with High Liquid Pressure Chromatography (HLPC) on the Frontal Cortex (FC), Ypothalamus (Y) and Striatum (S, on which were measured HVA and HVA/DA as well). Measurements of neurotransmitters …

Metabolic and hormonal responses in the regulation of blood glucose levels in infants delivered by elective caesarean section
… cortisol, catechols (EPI, NE, DA, DOPA, DHPG, DOPAC) and their sulfated conjugates (EPI sulfate, NE sulfate, DA sulfate, DOPA sulfate, DHPG sulfate, DOPAC sulfate), and blood gas and acid-base profiles. Results The mean maternal glucose and lactate levels were 4.28 mmol/l and 1.8 mmol/l …

The Effect of Cholecystokinin Antagonist Lorglumide on Dopamine Levels in the Rat Caudate
… of DA following α-mpt or by evaluation of DOPAC/DA ratios failed to reveal a significant difference when lorglumide-treated animals were compared to saline treated controls. Further, lorglumide did not alter basal or KC1-stimulated DA and serotonin release in the CPu as measured by …

The Effect of Resveratrol on Lipopolysaccharide-induced Dopaminergic Deficits and BV-2 Cell Activation
… of striatal 3, 4-dihydroxyphenylacetic acid (DOPAC) and DA content and tyrosine hydroxylase (TH) expression in the P21 animals. However, dietary resveratrol supplementation increased TH expression, DA and DOPAC levels in the P21 pups following prenatal exposure to LPS. Thus, these data suggest …

Electrical stimulation of reward sites in the ventral tegmental area of the rat increases dopamine transmission in the nucleus accumbens as measured by in vivo microdialysis
… dopamine (DA),3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) in the nucleus accumbens of the rat, prior to, during, and after 15-min periods of electrical brain-stimulation at sites in the ventral tegmental area (VTA) that supported …

Synthetic and Natural Environmental Compounds as Potential Facilitators of Mptp-Induced Parkinsonism
… Mn attenuated the effect of MPTP on striatal DOPAC, and facilitated the effect of MPTP on cortical DA and DOPAC. Mn also attenuated the MPTP induced decrease in cortical DAT. While these data support the notion that insecticides can produce tissue damage in the nigrostriatal pathway, in this …

Neurochemical Effects of Concurrent Exposure to Repeated Stress and Chlorpyrifos on the Central Nervous System
… norepinephrine but increased concentrations of DOPAC in the HT. Swim stress increased concentrations of dopamine in the HT more than control or restraint. CPF did not alter concentrations of norepinephrine, dopamine, or DOPAC in the HT. The interactions of repeated stress and CPF on serotonin …

The Effect of Organophosphate Exposure on Neocortical, Hippocampal and Striatal Monoamines: A Potential Substrate for Chronic Psychiatric, Cognitive and Motor Dysfunction
… increase in median dihydroxyphenylacetic acid (DOPAC) concentration (P=0.019) and a very strong statistical trend toward increased dopamine (DA) concentration (P=0.0506). The second experiment examined the time course of AChE inhibition produced by a higher dose (200mg/kg) of CPS and how …

Pesticides and pesticide combinations on brain neurochemistry
… analyzed by HPLC for catecholamines (dopamine, DOPAC, homovalinic acid and norepinephrine) and indolamines (serotonin and 5-HIAA). In general low doses of permethrin and endosulfan alone and in combination (EN 2.15 + PR 15 mg/kg) altered the levels of catecholamines and indolamines in both …

The Role of CLOCK in Regulation of Dopamine Neurotransmission in the CLOCKdelta19 Mutant Mouse Model
… striatum revealing significant increases in DOPAC and HVA. Dopamine receptor agonists and antagonists were used to pharmacologically probe dopamine receptor function. An enhancement of the locomotor suppressing response to dopamine antagonists in Clockdelta19 mice suggested increased …

Effects of MPTP, MPP(+) and Adreno-Medullin on Dopamine Metabolism in the Rat Corpus Striatum
… oxidized into 3,4-dihydroxyphenylacetic acid (DOPAC) and (3) a glycoprotein, tentatively named adrenomedullin, is present in the adrenal gland and has potent dopamine-releasing activity in the corpus striatum.

Analysis of rat brain lipids and metabolites after antidepressant drug treatment
… metabolite 3, 4- dihydroxyphenylacetic acid (DOPAC). In conclusion, findings of this project are supportive of a putative role for sphingolipids in the mechanism of action by antidepressant drugs. The potential clinical significance of these findings requires further studies.

The Effect Of An Intermittent Manganese (ii) Exposure On The Striatal Dopamine System
… reduction in intracellular dopamine and DOPAC levels were observed at all three time points. Interestingly, no matter the dose of MnCl2 administered intracellular cortical dopamine levels were significantly altered. These results suggest that a target brain region of excess Mn exposure is …

Developmental Monoamine Signaling Impacts Adult Affective and Aggressive Behaviors
… challenge in adulthood and striatal dopamine and DOPAC content is increased while brainstem 5-HIAA content is decreased in high aggression. Taken together, these data suggest that genetic and pharmacologic factors impacting dopamine and serotonin signaling during sensitive developmental periods …
