The short and long term effects of chromium toxicity on brain catecholamines and acetylcholinesterase levels were investigated. Rats were injected daily with varying amounts of chromium. The short term (2 h) administration of chromium (8 mmol/kg) reduced catecholamines level of cerebellum, mid-brain and brain-cortex by 22.8, 19.4 and 21.2% respectively. Acetylcholinesterase activity was also re...

     A simple, rapid, selective and highly sensitive fluorimetric method for determination of two catecholamines, i.e. norepinephrine (NE) and epinephrine (EP), in serum samples was developed. The method is based on the fluorescence sensitization of terbium (Tb3+) by complexation with both catecholamines in the presence of lanthanum (La3+), as a co-cation, and in a Na...

 Material methods. The number granules was determined silver nitrate impregnation under conditions administration anapriline -adrenergic receptor blocker (2 mg/kg), acute stress, activation noradrenergic systems (maprot...

Catecholamines and acetylcholine have dissociable effects on large-scale cortical network activity behavior.

Abstract Catecholamines are neurotransmitters in the peripheral and central nervous systems, which maintain normal physiological state of human body. Studies have shown that occurrence many diseases often accompanied by changes catecholamine levels. Clinically, detection levels plasma or urine can assist diagnosis endocrine-related neurological diseases. However, catecholamines easily oxidized,...

Abstract The neuroimmune system is complex and regulated by small chemical messengers released from resident immune neuronal cells. Catecholamines like dopamine norepinephrine are important responsible for initiating propagating messages between neurons cells; however, the mechanism dynamics of this signaling relatively unknown. presence intracellular machinery to synthesize interact with catec...

Brain nicotinic acetylcholine receptors (nAChRs) reportedly suppress the micturition, but mechanisms responsible for this suppression remain unclear. We previously reported that intracerebroventricularly administered (±)-epibatidine (non-selective nAChR agonist) activated sympatho-adrenomedullary system, which can affect micturition. Therefore, we investigated (1) whether (±)-epibatidine-induce...
