It is well known that systemic administration of morphine results in a depres-sion of respiration and cough reflex.Its mechanism has been considered to in-volve a depression of the brain stem respiratory neurones.But,few direct eviden-ces were available until recently Denavit-Saubié et al.demonstrated in cat thateither morphine or methionine-enkephalin was able to depress the activities ofthe brain stem respiratory neurones.In the present study,we observed the ef-fects of morphine applied microiontophoretically on respiratory as well as non-respiratory neurones in the region of the solitary tract at the level of obex.Experiments were carried out on 29 rabbits.Animals were anaesthetizedwith urethane(1 g/kg i.v.)in most cases,but a few experiments were performedon paralysed conscious rabbits.Procaine was infiltrated wherever skin incisionwas made.The animals were then immobilized with gallamine triethiodide andventilation was maintained by a respirator pump.Five-barrel glass micropipet-tes were used to record the extracellular activity and to iontophorese the drugions.A medical data processing computer was used on line to generate the spikefrequency histograms.The effects of morphine given iontophoretically on theunit discharge rate were examined.Of the 61 respiratory units recorded,6 wereexcited and the remainder were not influenced.Neither the spontaneous ac-tivity nor the glutamate-induced excitation of the respiratory units was seen to bedepressed by iontophoretic application of morphine.On the other hand,whileapplied on 49 non-respiratory units,morphine depressed 19,excited 3 and hadno effect on the remaining 27 units.Naloxone administered iontophoreticallyblocked morphine-induced depression six out Of fourteen times,but did not blockmorphine-induced excitation in our experiments.Our results indicate that the respiratory neurones in the region of the solitarytract are less sensitive to morphine and glutamate than the non-respiratory neu-rones in the same area.It is probable that in rabbit the depression of the respira-tory neurones in the region of the solitary tract by systemic morphine is broughtabout through an indirect way.

用五管微电极在家兔延髓孤束区记录单位活动并观察微电泳给予吗啡时对单位活动的影响。在61个呼吸性单位中,吗啡引起兴奋的单位有6个,其余55个活动无明显改变。没有看到吗啡引起明显阻遏的单位。在49个非呼吸性单位中,吗啡引起阻遏的有19个,兴奋的3个,其余27个活动无明显改变。在吗啡引起阻遏的单位中,有43%的单位吗啡效应可被纳洛酮对抗。没有看到纳洛酮能对抗吗啡的兴奋效应。上述结果表明家兔延髓孤束区中的呼吸性单位对吗啡和谷氨酸的敏感性比同一区域内的非呼吸性单位低。静脉内注射吗啡所引起的呼吸抑制效应并不是吗啡对该区域内呼吸性神经元的直接作用。

Our previous experiments revealed that the respiratory neurones in the region of the solitary tract are less sensitive to morphine. The possible explanation for the difference between our results and that of Denavit-Saubie was the different region observed. In this study, we observed the effects of morphine applied microiontophoretically on respiratory as well as non-respiratory neurones in the region of the nucleus ambiguus.Experiments were carried out on 24 rabbits.

Our previous experiments revealed that the respiratory neurones in the region of the solitary tract are less sensitive to morphine. The possible explanation for the difference between our results and that of Denavit-Saubie was the different region observed. In this study, we observed the effects of morphine applied microiontophoretically on respiratory as well as non-respiratory neurones in the region of the nucleus ambiguus.Experiments were carried out on 24 rabbits. All the experiments were performed on conscious paralysed rabbits. The animals were bilaterally vagotomized, immobilized with gallamine triethiodide and ventilated by a respirator pump. A medical data processing computer was used on line to generate the spike frequency histograms. The effects of morphine given iontophoretically on the unit discharge rate were examined. Of the 54 respiratory (29 inspiratory and 25 expiratory) units recorded, 10 were depressed, 1 was excited and the remainder were not influenced. Naloxone administered iontophoretically blocked morphine-induced depression in 5 out of 6 trials. While applied on 49 non-respiratory units, morphine depressed 13, excited 10 and had no effect on the remaining 26 units. Naloxone blocked morphine-induced depression in 5 out of 6 trials, but did not block morphine-induced excitation.Our results indicate that the respiratory neurones in the region of the nucleus ambiguus may be depressed by morphine directly, but the percentage of depressed respiratory neurones observed is less than that of the non-respiratory neurones.

用五管微电极在家兔疑核区记录单位活动并观察微电泳吗啡时对单位活动的影响。在54个呼吸性单位中,吗啡引起阻遏的有10个,兴奋的1个,其余43个活动无明显改变。在6个吗啡引起阻遏的单位中,有5个单位的吗啡效应可被纳洛酮对抗。在49个非呼吸性单位中,吗啡引起阻遏的有13个,兴奋的有10个,其余26个活动无明显改变。在6个吗啡引起阻遏的单位中,有5个单位的吗啡效应可被纳洛酮对抗;在7个吗啡引起兴奋的单位中,吗啡的兴奋效应均不能被纳洛酮对抗。本实验观察到疑核区的呼吸性单位有一部分能被吗啡阻遏,但呼吸性单位对谷氨酸和吗啡敏感的比例均明显地比非呼吸性单位的比例低。
