Recurrence of asthma following removal of a noradrenaline-secreting phaeochromocytoma.
A patient with asthma and a phaeochromocytoma is described. At about the time she was first noted to be hypertensive her asthma resolved spontaneously but bronchospasm returned with some severity when the tumour was removed. The phaeochromocytoma was of the noradrenaline secreting variety. Possible mechanisms through which this catecholamine might have produced the observed alleviation of asthm...
متن کاملCNS Noradrenaline and Pain
IAntinociceptive at the spinal level Adding NA is antinociceptive The story gets complicated because NA both inhibits and facilitates spinal nociceptive reflexes Spinal NA increases with acute and chronic nociceptive stimuli. NA tonically induces antinociception NA spinal denervation produces hyper and hypoalgesia NA spinal denervation retards the appearance of autotomy and neuropathic pain NA ...
متن کاملNoradrenaline and Parkinson's Disease
Parkinson's disease (PD) is characterized by the degeneration of dopamine (DA) neurons in the substantia nigra pars compacta, and motor symptoms including bradykinesia, rigidity, and tremor at rest. These symptoms are exhibited when striatal dopamine concentration has decreased by around 70%. In addition to motor deficits, PD is also characterized by the non-motor symptoms. However, depletion o...
متن کاملIntrathoracic chemodectoma with noradrenaline secretion.
Tumours arising in the chemoreceptor system are termed chemodectomas. Intrathoracic chemodectoma is a rare tumour, only 74 cases having been described by 1977.1 Systemic catecholamine secretion by an intrathoracic chemodectoma is very uncommon andwe have been able to trace only one other published case report of proven catecholamine secretion. We describe a second case and discuss briefly these...
متن کاملSerotonin Noradrenaline Reuptake Inhibitors (SNRIs)
Antidepressants that block the reuptake of serotonin (5-HT) and noradrenaline (NA) are called 5-HT and NA reuptake inhibitors (SNRIs). SNRIs are agents that show “dual action” on 5-HT and NA. These drugs bind the 5-HT transporters (SERT) and NA transporters (NAT) similar to tricyclic antidepressants (TCAs). However, SNRIs differ from TCAs in that SNRIs do not exert much affinity for other recep...
