... physiological and cellular stress responses following a 1 h heat shock in juvenile fish in dominance hierarchies. We measured stress hormone (cortisol and catecholamines) concentrations and blood, brain and liver tissue levels of three heat shock proteins (HSPs), the stress inducible HSP70, the constitutive...

... with a strong preference for aromatic catechol-branched substrates, especially phenylalanine and its derivatives tyrosine and L-DOPA,but not catecholamines. It represents a previously unknown SNF phenotype, and also appears to be the first sodium-dependent B 0 type transporter with a narrow selectivity...

...B. McNeill; S. F. Perry SUMMARY An in situ saline-perfused posterior cardinal vein preparation was used to assess the role of nitric oxide (NO) in the regulation of basal and stimulus-evoked catecholamine secretion from rainbow trout Oncorhynchus mykiss chromaffin cells. Addition of the NO donor...

... alone. Administration of exogenous catecholamines(10 and 100 nmol kg -1 adrenaline) to fish with intact brains and minimal surgical preparation reduced both respiratory frequency and amplitude,suggesting that humoral release of adrenaline also could not be responsible for the increase in breathing...

..., immature erythrocytes to catecholamine stimulation was greater than that of mature erythrocytes. In addition, the membrane fluidity, measured using the steady-state fluorescence polarisation method, was greater in anaemic fish after 24 days of recovery from bleeding than in control fish. Since blood from...

... pressures and systemic vascular resistance during hypercapnia but did not influence the CO 2 -induced bradycardia. Plasma levels of catecholamines did not change during hypercapnia, and therefore the stimulation of the systemic α-adrenoreceptors presumably reflected increased sympathetic nerve activity...
