Effect of vasotocin and glucagon on plasma growth hormone levels in the pigeon

Flight Effects on Plasma Levels of Neurohypophysial Hormones in Homing Pigeons

“…That AVT has indeed an adipokinetic action has been demonstrated in pigeon in vivo and also in in vitro experi ments [56] using pigeon adipose tissue slices [57], an action that may be mediated by cAMP [58], In this context, it may be men tioned that the release of AVT from the poste rior lobe in migratory birds prior to migration has been considered as an important event in the initiation of Spring migratory activity [59]. It should, however, be conceded that in birds, AVT is not to be regarded as a principal adipokinetic hormone like glucagon but could be more effective by its synergistic action with glucagon [51 ].…”
