Renal denervation supersensitivity revisited.
To determine whether the chronically denervated kidney is supersensitive to either physiological or pathophysiological plasma levels of norepinephrine (NE), studies were conducted in conscious dogs subjected to unilateral renal denervation and surgical division of the urinary bladder into hemibladders to allow separate 24-h urine collection from denervated and innervated kidneys. Plasma NE conc...
متن کاملDoes cerebral vasospasm result from denervation supersensitivity?
This study examined the role of denervation supersensitivity in the development of cerebral vasospasm. Adrenergic denervation of cat basilar artery was accomplished by resection of the superior cervical ganglia or by injection of 6-hydroxydopamine into the cisterna magna. In vivo dose-response characteristics were determined for normal and for denervated arteries, and no significant differences...
متن کاملDenervation supersensitivity to serotonin in rat forebrain: single cell studies.
To investigate the development of denervation supersensitivity to serotonin (5-hydroxytryptamine, 5-HT) in the amygdala (AMYG) and the ventral lateral geniculate nucleus (vLGN), single cell recordings, microiontophoretic, histochemical and biochemical techniques were used in the present study. 5-HT projections to the vLGN and the AMYG were destroyed by 5,7-dihydroxytryptamine (5,7-DHT, a relati...
متن کامل"Prespondylosis" and some pain syndromes following denervation supersensitivity.
Pain is determined by the neurologic properties of receptor organs, neurons, and their interconnections. These may become supersensitive or hyperreactive following denervation (Cannon's Law). A common cause of denervation in the peripheral nervous system is neuropathy or radiculopathy as a sequel to spondylosis. Spondylosis in its early stage may be "asymptomatic" or painless and hency unsuspec...
متن کاملDenervation supersensitivity: the response to depolarizing muscle relaxants.
The chemical theory of neuromuscular transmission (Dale, Feldberg and Vogt, 1936) is now almost universally accepted, and implicates acetylcholine as the neuromuscular transmitter. Depolarizing muscle relaxants act, at least initially, in a manner similar to acetylcholine and are believed to produce their effects by prolonged depolarization, but in certain situations these agents, instead of pr...
