Neurotransmission through sympathetic ganglia of spontaneously hypertensive rats.
Transmission of neuronal activity was assessed by recording preganglionic and postganglionic compound action potentials in superior cervical ganglia isolated from adult spontaneously hypertensive rats (SHR), Wistar-Kyoto (WKY) rats, and Wistar rats as well as young SHR and WKY rats to determine if previously observed alterations of membrane excitability, synaptic transmission, or both, have an ...
متن کاملAdrenergic neurotransmission in vascular smooth muscle from spontaneously hypertensive rats.
The goal of this study was to compare adrenergic neurotransmlssion in isolated vascular smooth muscle from spontaneously hypertensive (SHR) and normotensive rats. Tail arteries, excised from adult SHR and normotensive rats, were cut helically into strips that were mounted in organ chambers between two platinum wire electrodes; isometric contractions were recorded. Vascular responsiveness was de...
متن کاملLoss of accommodation in sympathetic neurons from spontaneously hypertensive rats.
Synaptic transmission and membrane properties of sympathetic neurons in superior cervical ganglia of spontaneously hypertensive rats (SHR), normotensive Wistar-Kyoto rats (WKY), and Sprague-Dawley rats (SD) were investigated in vitro by extracellular and intracellular recording. The sympathetic neurons of SHR showed an atypical loss of spike accommodation. The spike discharge was insensitive to...
متن کاملExcitatory sympathetic reflex in NaCl-sensitive spontaneously hypertensive rats.
We have previously demonstrated blunted reflex responses of lumbar sympathetic nerve activity during volume expansion in NaCl-sensitive spontaneously hypertensive rats maintained on basal (1% NaCl) diets compared with NaCl-resistant spontaneously hypertensive rats, Wistar-Kyoto rats, and Sprague-Dawley rats. The current study tested the hypothesis that chronic ingestion of a high (8%) NaCl diet...
متن کاملExaggerated sympathetic responses to bradykinin in spontaneously hypertensive rats.
Possible defects in blood pressure (BP) regulation were studied by recording responses to centrally-administered bradykinin. Pressor effects accompanied by increased sympathetic nerve activity were elicited by intracerebroventricular injections in intact rats, but significant differences between Kyoto-Wistar normotensive (KNR) and spontaneously hypertensive rats (SHR) were not detected. By cont...
