Title: The effect of sympathomimetic agents on noradrenaline efflux from a blood vessel. Author: Frost BR, Frewin DB, Downey JA. Journal: Eur J Pharmacol; 1980 Oct 03; 67(1):85-9. PubMed ID: 7418734. Abstract: The effect of several sympathomimetic agents on the efflux of noradrenaline and its metabolites has been evaluated using the ventral artery of the rat tail as the experimental model. This vessel is richly endowed with sympathetic nerves and is therefore well suited to examine the efflux patterns of that transmitter. Etilefrine, tyramine, ephedrine and REN-293 were all found to increase the efflux of 3H-noradrenaline and/or 3H-DOPEG to different degrees from the artery. Possible reasons for this variation in metabolite efflux are discussed.[Abstract] [Full Text] [Related] [New Search]
