Responsiveness of Equine Basilar Artery to Transmural Nerve Stimulation Differs from That of Porcine and Bovine Basilar Arteries in Vitro

[摘要] References(11)Cited-By(2)Transmural nerve stimulation (TNS) induced relaxations in porcine and bovine basilar arteries which were abolished by tetrodotoxin (TTX) and by L-nitro-arginine (LNAG). However, TNS induced contractions in equine basilar artery which were abolished by TTX and by guanethidine, but not by LNAG. These results suggest that the TNS-induced contractions of equine basilar arteries may be mediated by norepinephrine release.
