The superior cervical sympathetic ganglion was decentralized unilaterally by section of the preganglionic chain in 2- or 4-day-old rats. Twenty-one days post-operatively the dilator muscle of the iris was examined electron microscopically. Quantitative estimates demonstrated that there was a reduction both in the numbers of axon bundles and of individual axons in the iris innervated by the deafferented ganglion as compared with its fellow of the contralateral control side.
在2日龄或4日龄大鼠中，通过切断节前神经链单侧去交感神经支配颈上神经节。术后21天，对虹膜的瞳孔开大肌进行电子显微镜检查。定量评估表明，与对侧对照侧的相应部位相比，去传入神经节支配的虹膜中轴突束和单个轴突的数量均减少。
