Catecholamines and platelet aggregation were studied in relation to physical fitness and psychologic traits of 48 young men at rest and after exercise challenge. Test scores were significantly associated with variables derived from the in vitro reactivity of blood platelets. Men characterized by high time urgency, impatience, haste and irritability had higher platelet counts in their whole bloo...

In this light microscopic immunocytochemical study beta-Endorphin (beta-END), leu-enkephalin and dopamine-beta hydroxylase (DBH) antisera are used to obtain an overview of the interaction of the noradrenergic and opiate peptide systems in brain. Serial brain areas were analyzed for DBH and then for beta-END or leu-enkephalin. Several areas were evaluated for cell and fiber interactions between ...

The combination of inhaled nitric oxide with almitrine bismesylate has been proposed for the management of acute respiratory distress syndrome in order to divert pulmonary blood flow away from poorly ventilated toward well-ventilated areas. The aims of this prospective and comparative study were to: 1) confirm the beneficial effects on oxygenation of this association; 2) evaluate the haemodynam...

Effects of drugs influencing the activity of the hypothalamic noradrenergic system on the carbachol-induced emotional-defensive response were investigated. Intrahypothalamic injections of noradrenalin, amphetamine and reserpine did not produce any changes in cats' behavior. Injections of carbachol into the same hypothalamic loci, following the injections of noradrenalin, amphetamine or reserpin...

Antidepressants are first-line treatment for patients with major depressive disorder (MDD). The mechanism of action of antidepressants is still not completely understood. While most antidepressants directly inhibit the reuptake of at least one monoamine neurotransmitter in the brain (serotonin, dopamine or noradrenalin), or block their degradation, mirtazapine, tianeptine and agomelatine, which...

Somatostatin receptor scintigraphy (SNS) with In-labelled somatostatin receptor analog is a standard procedure for the detection and staging of neuroendocrine tumors (NETs, APUDomas). NETs can be small and situated almost throughout the body. This heterogeneous group of tumors take up amino acids, transform them into biogenic amines (dopamine and serotonin) by decarboxylation, and store the ami...
