5-HT and 5-HIAA were measured in cat cerebral arteries by HPLC. Removal of both superior cervical ganglia or simultaneous lesions of dorsal and central raphe nuclei significantly decreased 5-HT levels but not those of 5-HIAA. This suggests that cat cerebral blood vessels are innervated by serotonergic fibers of different origin.
采用高效液相色谱法测定猫脑动脉中的5-羟色胺(5-HT)和5-羟吲哚乙酸(5-HIAA)。切除双侧颈上神经节或同时损伤中缝背核和中央中缝核,可使5-HT水平显著降低,但5-HIAA水平不受影响。这表明猫脑血管受不同来源的5-羟色胺能纤维支配。
