Pharmacological analysis of dopamine action on the isolated dog atrium.
The isolated right atrium of the dog was perfused with arterial blood introduced from a carotid artery of a support dog. The selective injection of dopamine, tyramine and norepinephrine into the cannulated sinus node artery induced dose-relatedly positive chronotropic and inotropic effects. However, for an equal increase in sinus rate, dopamine caused less increase in tension development than n...
متن کاملPharmacological comparison of isolated monkey and dog cerebral arteries.
Pharmacological differences between canine and monkey basilar arteries were studied in vitro. The constrictor response of canine basilar artery to either norepinephrine or an alpha 1-adrenoceptor agonist phenylephrine was partly inhibited by an alpha 2-adrenoceptor antagonist yohimbine but not by an alpha 1-adrenoceptor antagonist prazosin. The contraction elicited by an alpha 2-adrenoceptor ag...
