Nonadrenergic neural vasodilator mechanisms.
Vasomotor influences mediated through peripheral nerves were first demonstrated by Claude Bernarde. After many decades of experimentation, few doubt that the sympathetic outflow mediated through norepinephrine and epinephrine is the major physiological vasomotor mechanism. However, nonadrenergic nerves supply most regional vascular beds, and their possible influence must be taken seriously. In ...
متن کاملOn the action of adrenalin
In further illustration of Langley's generalisation that the effect of adrenalin upon plain muscle is the same as the effect of exciting the sympathetic nerves supplying that particular tissue, it is found that the urethra of the cat is constricted alike by excitation of the hypogastric nerves and by the injection of adrenalin. The sacral visceral nerves, on the other hand, relax the urethra of...
متن کاملFurther Appraisal of the Adrenalin
-TUNKENSTEIN, Greenblatt, and Solomon in 1948 reported on certain physiological changes which followed electroshock treatment. Since that time, several papers have appeared which have attempted to define the physiological meaning and the prognostic value of blood-pressure curves as they are affected by intravenous neo-epinephrine and intramuscular Mecholyl (methacholine). Funkenstein and his co...

متن کاملMechanisms of action of OPC-28326, a selective hindlimb vasodilator.
The unique cardiovascular profile of OPC-28326 [4-(N-methyl-2-phenylethylamino)-1-(3, 5-dimethyl-4-propionylaminobenzoyl)piperidine hydrochloride monohydrate] provides insight into basic mechanisms of this new drug as determined by experiments in dogs and rats. In anesthetized open-chest dogs, an i.v. administration of a low dose (0.3 and 1.0 microg/kg) of OPC-28326 selectively increased femora...
