目的:为厂确定沿迷走神经传入的心脏感觉纤维在左心房的分布情况.将CT-HRP注入豚鼠迷走神经下神经节,顺行标记沿迷走神经传入的心脏感觉纤维在豚鼠左心房的分布.结果:在左心房壁内观察到了大量的HRP阳性的顺行标记神经纤维和终末样分支:对这一发现与以前用同样方法研究沿交感神经传入的心脏感觉纤维进行了比较,并对这些纤维的意义进行了讨论.
OBJECTIVE: To determine the distribution of cardiac sensory fibers along the vagus nerve in the left atrium for the plant.CTR-HRP was injected into the inferior vagal ganglion of guinea pigs and the distribution of cardiac sensory fibers along the vagus nerve was markedly labeled in the left atrium of guinea pigs.Results : A large number of HRP-positive antegrade-labeled nerve fibers and terminal-like branches were observed in the left atrial wall: this finding was compared with the previous study of sympathetic afferent cardiac sensory fibers in the same way, and these The significance of fiber is discussed.
