The effect of chronic sympathetic and sensory denervation of the growing rabbit ear vasculature on myogenic tone in a resistance artery was studied. Unilateral superior cervical ganglionectomy and section of greater and anterior auricular nerves were performed at 4 wk of age. Compared with the contralateral control, 2 and 6 wk later, the denervated artery developed greater stretch-dependent myogenic tone. This phenomenon may partially account for the return of tone described in the denervated ear vasculature.
研究了对生长中的兔耳血管进行慢性交感神经和感觉神经去神经支配对阻力动脉肌源性张力的影响。在4周龄时进行单侧颈上神经节切除术以及切断耳大神经和耳前神经。与对侧对照相比，在去神经支配2周和6周后，去神经支配的动脉产生了更大的牵张依赖性肌源性张力。这种现象可能部分解释了去神经支配的耳血管中所描述的张力恢复情况。
