Abstract

In guinea-pig isolated tracheal tube preparations treated with dipyridamole, adenosine deaminase antagonized inhibitory responses to adenosine and non-adrenergic, non-cholinergic nerve stimulation. Inhibitory responses to vasoactive intestinal peptide (VIP) were unaffected and hyoscine-sensitive excitatory responses to field stimulation were not reduced. The evidence supports a role of adenosine as an inhibitory neurotransmitter in non-adrenergic, non-cholinergic nerves in trachea.

摘要

在用双嘧达莫处理的豚鼠离体气管制备物中,腺苷脱氨酶可拮抗对腺苷以及对非肾上腺素能、非胆碱能神经刺激的抑制反应。对血管活性肠肽(VIP)的抑制反应未受影响,对场刺激的阿托品敏感兴奋反应也未减弱。这一证据支持腺苷在气管非肾上腺素能、非胆碱能神经中作为抑制性神经递质的作用。
