摘要

实验用63只麻醉、制动、切断双侧颈迷走神经、人工呼吸的家兔,以延髓呼吸相关神经元(RRN)和膈神经放电(Phr.D)作为呼吸观测指标,观察了股动脉注射琥珀胆碱(Sch)诱发的肌梭传入活动对呼吸的影响。结果提示,肌梭的传入活动可通过延髓或延髓上中枢的下行作用参与对呼吸节律的反射性调节作用。

Abstract

Effect of muscle spindle afferent invoked by intraarterial injection of succinylcholine (Sch) on respiration was assessed by changes in unit discharge of respiration related neurons and phrenic nerve of 63 anesthetized, bilaterally vagotomized and artificially ventilated rabbits.
