Renal participation in enhanced pressor responses to noradrenaline in patients given hexamethonium.
Ganglion-blockers, such as tetra-ethylammonium (TEA) and hexamethonium, enhance responsiveness to vasoactive agents, both pressor and depressor (1). In dogs, the renal arterial bed seems to contribute to the change in blood pressure response since, after giving TEA, adrenaline causes a larger increase and isopropylnoradrenaline (Isuprel@) a larger decrease in renal vascular resistance than in t...
متن کاملRenal inhibition of pressor responses to drugs.
FIFTY-FIVE years ago Tigerstedt and Bergman found the pressor response to intravenously injected renin increased after bilateral nephrectomy; more recently, Page and Helmer showed similar augmentation of response to injection of angiotonin, the reaction product of renin and substrate. Consistent with an apparent inhibitory influence of functioning renal tissue on responses to injected renin and...
متن کاملPressor Responses to Norepinephrine During Captoprii In Renal Prehypertensive Rabbits
The role of angiotensin II (All) in pressor hyperresponsiveness was examined in conscious one-kidney, one clip rabbits with renal artery stenosis 01 3-days' duration (renal prehypertensive rabbits). Conscious one-kidney rabbits without renal artery stenosis served as controls. Two experiments were performed. The first experiment used four groups of six rabbits each, to examine the pressor respo...

متن کاملPressor action of noradrenaline in young dogs.
(Received for publication, January 3, 1958) The relative noradrenaline content of the adrenal gland in young animals was larger than that in adult ones.') Therefore, it is of interest to know whether the relative activities of noradrenaline to adrenaline in young animals differ from those in adult ones. In this view, the pressor action of noradrenaline was compared with that of adrenaline in yo...
