我们已经应用萤光组化法研究了家兔椎动脉颅内段交感纤维的分布型式,确定了这些纤维来源于同侧星状神经节。同时我们观察到切除一侧颈上神经节、或切除一侧星状神经节、或切除一侧整个颈交感干以后,对基底动脉上的萤光纤维都无显著影响,这提示基底动脉的交感纤维可能来源于双侧颈交感节。为了证实这个问题,本实验应用 Falck 萤光组 We have used fluorescence method to study the distribution pattern of intracranial sympathetic fibers in rabbit intracranial vertebral arteries, and confirmed that these fibers originated from ipsilateral stellate ganglion. At the same time, we observed that there was no significant effect on the fluorescent fibers in the basilar artery after resection of the superior cervical ganglion, or removal of the stellate ganglion, or removal of the entire cervical sympathetic trunk, suggesting that the basilar artery sympathetic Fibers may originate from bilateral cervical sympathetic joints. In order to confirm this problem, the experiment using Falck fluorescent group
