Differences in alpha-adrenergic responsiveness between human internal mammary arteries and saphenous veins.
Little is known regarding specific biologic and pharmacologic differences between human internal mammary arteries and saphenous veins. To better define the role of alpha-adrenoceptor-mediated vasoconstriction in human internal mammary arteries and saphenous veins, we obtained fresh specimens of both vessels from 32 patients undergoing coronary artery bypass surgery. Dose-response curves were ge...
متن کاملSeparation of Responses of Arteries and Veins to Sympathetic Stimulation
• The sympathetic innervation of the vascular tree consists of postganglionic fibers derived from the sympathetic ganglion cells in the cervical, thoracic, and lumbar regions of the sympathetic trunks. In most vascular beds the blood vessels receive their innervation from postganglionic nerves which accompany the main arterial vessels supplying the bed. Information is sparse, however, regarding...
