Renal adrenoceptor mediation of antinatriuretic and renin secretion responses to low frequency renal nerve stimulation in the dog.
We evaluated renal adrenoceptor mediation of the renin secretion and antinatriuretic responses to low frequency (1.0 Hz) electrical stimulation of the renal nerves in the dog using renal a-adrenoceptor blockade with phentolamine {a-i/a-i), prazosin (a,), yohimbine (a2), and rauwolscine (a2), and /3-adrenoceptor blockade with d,/-propranolol OS1//S2) and atenolol (/?,). In all animals studied, r...
متن کاملNeuronally Released Norepinephrine Does Not Preferentially Activate Postjunctional arAdrenoceptors in Human Blood Vessels in Vitro
Human isolated digital arteries and metatarsal veins, obtained postmortem, have been used to compare the effects of a-adrenoceptor antagonists on contractile responses to nerve stimulation. The antagonists used were prazosin, rauwolscine, BE 2254, and yohimbine. Rauwolscine ((^-antagonist), as well as prazosin and BE 2254 (ati-antagonists), in concentrations of 10", 10~", and 10 mol/liter, pote...
متن کاملAn investigation into the alpha-adrenoceptor mediating renal nerve-induced calcium reabsorption by the rat kidney.
An investigation was undertaken in pentobarbitone-anaesthetized rats to determine the sub-type of alpha-adrenoceptor responsible for the renal nerve-induced increases in the reabsorption of calcium and sodium by the tubules of the kidney. Stimulation of the renal nerves at low frequencies (0.8-1.5 Hz) did not change either renal blood flow or glomerular filtration rate but significantly reduced...
متن کاملHypothalamic #2-Adrenoceptor Control of Renal Sympathetic Nerve Activity and Urinary Sodium Excretion in Conscious, Spontaneously Hypertensive Rats
The contributions of /Si-, B -̂, and a2-adrenoceptors in the posterior hypothalamus to the increased renal sympathetic nerve activity and decreased urinary sodium excretion resulting from environmental stress (air jet) in conscious spontaneously hypertensive rats were examined. Air stress increased mean arterial pressure and renal sympathetic nerve activity (54% from 7.0 ± 0.7 integrator resets/...
