Cyclic adenosine 3',5'-monophosphage (cyclic AMP) levels in guinea-pig tracheal rings increased on incubation with the vasoactive intestinal peptide (VIP). The effect was potentiated by the addition of theophylline. The results suggest that the tracheo-bronchial relaxant action of VIP may be mediated by stimulation of tracheal adenylyl cyclase.
豚鼠气管环中3',5'-环磷酸腺苷(环磷腺苷)水平在与血管活性肠肽(VIP)一起孵育时会升高。茶碱的加入会增强这种作用。结果表明,VIP的气管支气管舒张作用可能是通过刺激气管腺苷酸环化酶来介导的。
