Differential labelling of intraneuronal noradrenaline stores with different concentrations of (-)-3H-noradrenaline.
Isolated preparations of the rabbit vas deferens were incubated with (--)-(3)H-nor- adrenaline. A preferential release of (3)H-noradrenaline was demonstrated after electrical stimulation of the intramural nerves in those tissues labelled with 10 ng/ml (3)H-noradrenaline. There was no preferential release of (3)H-noradrenaline when the vasa were initially labelled with 100 ng/ml (3)H-noradrenali...
متن کاملPlasma noradrenaline concentrations during isometric exercise.
Blood was collected simultaneously from the left ventricle and pulmonary artery in 12 patients undergoing routine cardiac catheterisation and was analysed for noradrenaline concentrations at rest, during, and after isometric stress (hand grip). Moderate isometric exercise resulted in a significant rise in plasma noradrenaline with a return to basal values 10 minutes after discontinuing the grip...
متن کاملAdrenaline and noradrenaline concentrations in rat tissues.
Noradrenaline and adrenaline concentrations have been little studied in rat tissues; this paper deals with their estimation by an extension ofthe method of Weil-Malherbe & Bone (1952, 1953, 1954) for blood; a brief report has already been presented (Montagu, 1955). The results do not appear to support the current hypothesis that the concentration of noradrenaline can be correlated with the dens...
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 کاملDifferential modulation of bovine epididymal activity by oxytocin and noradrenaline.
Passage of spermatozoa through the epididymis and emission of sperm during ejaculation are based on spontaneous and induced contractions of epididymal peritubular muscle layers. This study deals with the ejaculation-relevant factors noradrenaline (NA) and oxytocin (OT) and their contractile effects in the course of the bovine epididymal duct. Muscle tension recording revealed excitatory effects...
