A perivascular sympathectomy was performed at the base of the ear artery in 11 New Zealand white rabbits. Two days later three were killed, and the central nerve was cut in the remaining eight. The contralateral ear served as a control. Specimens were taken from the distal parts of both ears two days later and the glyoxylic acid-induced fluorescence method was used to show the adrenergic nerves. The arteries of the normal, control ear were surrounded by a dense plexus of fluorescent adrenergic nerves, which were abolished by perivascular sympathectomy only in the segment from which the adventitia had been removed. The adrenergic innervation was normal proximal to the site of perivascular sympathectomy, but there was a short segment of the central vessel distally in which it was diminished. No changes in adrenergic innervation were found in the distal third of the rabbit ear.
对11只新西兰白兔的耳动脉根部进行了血管周围交感神经切除术。两天后处死3只，其余8只切断中枢神经。对侧耳作为对照。两天后从双耳远端取材，采用乙醛酸诱导荧光法显示肾上腺素能神经。正常对照耳的动脉被密集的荧光肾上腺素能神经丛包围，仅在去除外膜的节段，血管周围交感神经切除术可将其消除。肾上腺素能神经支配在血管周围交感神经切除术部位近端正常，但在远端中央血管有一小段神经支配减少。在兔耳远端三分之一处未发现肾上腺素能神经支配有变化。
