Hormone Catecholamines

Catecholamines, derived from the amino acid tyrosine, produced by the adrenal glands, which are found on top of the kidneys. are epinephrine (adrenaline), norepinephrine (noradrenaline) and dopamine. The hormone are released into the blood during times of physical or emotional stress.

Hormone Dopamine: Dopamine and blood pressure and cerebral hemodynamics

In a Standard meta-analytic techniques, including random and fixed effects models used to calculate combined effect size correlations and significance levels showed that Dopamine administration increases mean and systolic blood pressure in hypotensive preterm infants, and is more effective than dobutamine, colloid or hydrocortisone alone. Dopamine administration is associated with increased CBF, with greater increases in CBF in hypotensive than in normotensive preterm infants. Dopamine is not associated with a greater incidence of adverse effects than other therapies used to treat hypotension(3).

Hormone Dopamine: The effects of Dopamine and dobutamine on heart rate

Hormone Dopamine: The effects of Dopamine and dobutamine on heart rate

In the study of twenty patients with symptomatic CHF (systolic dysfunction) were enrolled. After recording one-hour baseline electrocardiographs (ECGs), patients were randomly selected for either dopamine (4 micrograms/kg/minute, Group A) or dobutamine (4 micrograms/kg/minute, Group B) treatment for three days, conducted by Taichung Veterans General Hospital, found that Dopamine and dobutamine have comparable therapeutic effects in patients with CHF, but low-dose dopamine more favorably affects cardiac autonomic function(2).

Hormone Dopamine: Dopamine and Attention deficit hyperactivity disorder

Hormone Dopamine: Dopamine and Attention deficit hyperactivity disorder

Through neuromodulatory influences over fronto-striato-cerebellar circuits, dopamine and noradrenaline play important roles in high-level executive functions often reported to be impaired in attention-deficit/hyperactivity disorder (ADHD). According to the study by University of Cambridge, Cambridge, United Kingdom, Medications used in the treatment of ADHD (including methylphenidate, dextroamphetamine and atomoxetine) act to increase brain catecholamine levels. However, the precise prefrontal cortical and subcortical mechanisms by which these agents exert their therapeutic effects remain to be fully specified(5).

Hormone Dopamine: Acetylcholine-dopamine and CNS disorders

Hormone Dopamine: Acetylcholine-dopamine and CNS disorders

The substantia nigra pars compacta and ventral tegmental area of midbrain dopaminergic nuclei and their respective forebrain and cortical target areas are well established as serving a critical role in mediating voluntary motor control, as evidenced in Parkinson's disease, and incentive-motivated behaviors and cognitive functions, as exhibited in drug addiction and schizophrenia, respectively. According to the study by The University of Memphis, acetylcholine may be as important in regulating dopaminergic transmission. Midbrain dopaminergic cell tonic and phasic activity is closely dependent upon projections from hindbrain pedunculopontine and the laterodorsal tegmental nuclei, which comprises the only known cholinergic inputs to these neurons(1). Other study indicated that combinatorial signaling through dopamine and serotonin (DA and 5-HT) receptors can regulate the brain region- and cell-type specific pMeCP2 in the CNS(1a).

Hormone Norepinephrine: Peripheral hormone epinephrine (EPI) and brainstem nuclei

Hormone Norepinephrine: Peripheral hormone epinephrine (EPI) and brainstem nuclei

The peripheral hormone epinephrine (EPI) is known to modulate memory for arousing experiences. In the study to test the hypothesis of the actions of EPI on the LC suggest that its mnemonic properties may also be mediated by influencing NE output in the HIPP, dialysate levels of NE were collected from the HIPP of male rats given an i.p. injection of saline that was followed 100 min later by i.p. EPI (0.3 mg/kg). NE levels sampled 20 min after EPI injection were significantly larger than baseline and continued to show significant peaks for 60 min found that the mnemonic effects of EPI reported in a wide range of learning conditions may not be mediated solely by NE release in the amygdala, but may also involve coactivation of the HIPP NE system, according to the study by The University of Virginia(13).

Hormone Norepinephrine: Actions of norepinephrine in the cerebral cortex and thalamus

Hormone Norepinephrine: Actions of norepinephrine in the cerebral cortex and thalamus

Norepinephrine (NE) has potent and long-lasting ionic effects on cortical and thalamic neurons. In the study by Yale University School of Medicine, indicated that In cortical pyramidal cells, activation of beta-adrenergic receptors results in an enhanced excitability and responsiveness to depolarizing inputs. This enhanced excitability is expressed as a reduction in spike frequency adaptation and is mediated by a marked suppression of a slow Ca(++)-activated potassium current known as IAHP. In the thalamus, application of NE results in the suppression of ongoing rhythmic burst activity and a switch to the single spike firing mode of action potential generation. This effect is mediated through an alpha 1-adrenergic suppression of a resting leak potassium current, IKL, and through a beta-adrenoceptor-mediated enhancement of the hyperpolarization activated cation current Ih(12).

Hormone Norepinephrine: Norepinephrine and Cerebellum

Hormone Norepinephrine: Norepinephrine and Cerebellum

Presynaptic modulation of synaptic transmission is the primary function of central nicotinic acetylcholine receptors (nAChRs) in developing and adult brain. nAChR activation regulates release of various neurotransmitters, including norepinephrine(NA). In the study of to determine whether nAChRs modulate NA release in developing cerebellum. In vitro experiments using cerebellar slices examined the effects of nAChR stimulation on release of radiolabeled NA ([3H]NA), showed that these data support recent findings of a possible functional role of nAChRs in regulating cerebellar ontogeny, and provides further support for the role of NA as a neurotrophic factor during development(14).
