Our present concepts of the role and use of epinephrine and norepinephrine in man are largely based on the doctrine of epinephrine as the emergency hormone of the adrenal medulla, originally outlined by Cannon and his associates, and the more recent finding that norepinephrine serves as ...
Epinephrine and norepinephrine dilated the pupil and retracted the nictitating membrane of the denervated side, whereas amphetamine dilated both pupils and retracted both nictitating membranes. Phenoxybenzamine (4 mg/kg) constricted primarily the pupil of the innervated iris and completely antagonized the...
Acetylcholine effectively blocked the positive inotropic action of epinephrine without altering the response to calcium in electrically stimulated isolated perfused turtle and rabbit ventricles. This blocking action of acetylcholine was readily antagonized by atropine. Acetylcholine also blocked the positive inotr...

Iontophoresis of SP onto cells of the IML produces excitation of sympathetic preganglionic neurons in the rat [5,6]. In addition, the intrathecal (i. th.) injection of SP at T9 spinal level increases plasma concentrations of epinephrine and norepinephrine which can be antagonized by the SP ...
At 10 to 20 mg/kg i.v., the drug lowered blood pressure and reduced the pressor effects to epinephrine and norepinephrine. In dogs with blood pressure lowered by blood withdrawal or histamine infusion benzquinamide had a pressor effect in spite of sodium pentobarbital anesthesia. This effect ...

Place the following hormones into one of the three categories of hormones (peptides‚ amines or steroids): T4 (thyroxin)‚ estradiol‚ norepinephrine‚ insulin‚ aldosterone‚ glucagon‚ cortisol‚ growth hormone‚ T3 (triiodothyronine)‚ epinephrine‚ testosterone and vasopressin (ADH)...
Wy-5244 exerted characteristic effects on the cardiovascular actions of other agents. The compound antagonized the pressor and positive inotropic actions of several indirectly-acting sympathomimetic amines while the pressor effects of norepinephrine, epinephrine, phenylephrine, dimethylphenylpiperazinium and ...
