Experiments were performed on 63 rabbits anaesthetized with urethane, immobilized by d-tubocurarine and under artificial respiration.The action potentials of both the phrenic and the cervical sympathetic nerves were recorded.The sympathetic nerve was found to show,usually after a lag of 0.2—0.3sec,an increase of tonic activity with each bUrst of the phrenic discharges,thus displaying a respiratory rhythm.This respiratory rhythm of the sympathetic activity occurred regularly provided that the pons and medulla remained intact,and it was not affected by sectioning of the buffer nerves. It became more marked under the influence of such factors as artificial deflation of the lungs,bilateral vagotomy,asphyxia and inhalation of CO_2 or pure nitrogen.And it showed the opposite change with artifical inflation of the lungs,hyperventilation,injection of adrenaline or pentothal sodium. On the basis of the results obtained,it is thought that the excitation of the respira- tory center can“irradiate”to the vasomotor center,thereby producing the respiratory rhythm of the sympathetic discharges.The process of irradiation is assumed to be me- diated through a series of synaptic transmissions within the pontine-medullary reticular formation.

(一)兔颈交感神经干的动作电位和膈神经发放有明显的同步关系,是为交感发放的呼吸性节律。改变呼吸中枢和血管运动中枢的兴奋状态后,交感发放的呼吸性节律也随着发生相应的变化,但切断缓冲神经不影响交感的呼吸性节律发放。(二)必须保留脑桥和延髓完整,交感发放才能表现出呼吸性节律。在脑桥水平切断脑干而动物发生长吸式呼吸时,交感发放的呼吸性节律消失。(三)本文讨论了交感神经和膈神经同步化发放的机制,认为呼吸中枢的兴奋过程使血管运动中枢的活动被周期性地“强化”。于是交感发放出现呼吸性节律。呼吸中枢对血管运动中枢的“强化”的程度,乃取决于这两个中枢的兴奋性的高低,这一过程可能是在脑桥和延髓的网状结构中进行的。

Tachyphylaxis to ephedrine has been studied on the cat's nictitating membranes, the cat's and the rat's blood pressure. In the course of the development of tachyphylaxis to ephedrine in cats, it was found that: (1)the cumulative effect(probit) of ephedrine on nictitating membranes could be plotted linearly against its cumulative dose(log)(Fig.3), (2)the responses of nictitating membranes to supramaximal electrical stimuli on the cervical sympathetic nerve diminished, and (3) both the pressor and the nictitating...

Tachyphylaxis to ephedrine has been studied on the cat's nictitating membranes, the cat's and the rat's blood pressure. In the course of the development of tachyphylaxis to ephedrine in cats, it was found that: (1)the cumulative effect(probit) of ephedrine on nictitating membranes could be plotted linearly against its cumulative dose(log)(Fig.3), (2)the responses of nictitating membranes to supramaximal electrical stimuli on the cervical sympathetic nerve diminished, and (3) both the pressor and the nictitating membrane responses to intravenous noradrenaline increased. Tachyphylaxis to the pressor effect of ephedrine in rats was found to be easily induced by repeated intravenous doses of 8mg/kg each at short intervals(Fig.6).After the development of tachyphylaxis to ephedrine in rats,the dose-pressor-response curve of tyramine was depressed (Fig.7), while that of noradrenaline was not altered significandy. In cats pretreated with reserpine (2.5—5mg/kg), the response of nictitating membranes was depressed significantly at the dose of 2.5mg/kg on the dose-response curve of ephedrine (Fig.4). On the contrary, the dose-pressor-response curves in reserpinized cats and rats were elevated at the last and maximal dose of ephedrine (12.5mg/kg in cats; 8mg/kg in rats) in comparing with controls in which the response to the last dose had been depressed due to the development of tachyphylaxis (Fig. 5,9). In rats pretreated with reserpine in different schedules (5mg/kg, 3—4 hours previously; 1mg/kg daily for 5 days and 7mg/kg daily for 2 days), the development of tachyphylaxis tended to be delayed and the pressor effect of the first dose of ephedrine was potentiated especially during the acute influence of a 5mg/kg dose of reserpine. Bilateral adrenalectomy made no significant difference in the results of some of the above experiments (Fig.9, Tab.4). Infusion of noradrenaline in the beginning of the rat experiments could also potentiate the pressor effect of ephedrine, but unlike reserpinization, it hastened the development of tachyphylaxis in most cases. If noradrenaline was infused after tachyphylaxis, it could partially restore the pressor effect of ephedrine injected during the infusion (Fig.8). After cocaine(2.5mg/kg, i.v.), the dose-pressor-response curve was depressed and the development of tachyphylaxis hastened (Fig.10). These results would suggest the coexistence of two important factors in the development of tachyphylaxis to ephedrine: (1) tachyphylaxis to the direct action of ephedrine is due to saturation of receptors; (2) tachyphylaxis to the indirect action of ephedrine is due to depletion of catechol amines.

本文对于猫瞬膜,猫及大鼠血压对麻黄碱的快速耐受性进行了系統研究。在猫对麻黄碱快速耐受性产生过程中发现:(1) 麻黄碱对瞬膜的积累作用(机率)与积累剂量(对数)呈直线关系,(2) 瞬膜对电刺激交成神经的反应减弱,(3) 血压及瞬膜对静脉注射去甲腎上腺素的反应增加。与其他实驗动物相似,大鼠連续注射麻黄碱8毫克/公斤,其升压作用也易于产生快速耐受性。大鼠血压对麻黄碱产生快速耐受性后,酪胺的剂量反应曲线被压低,但去甲腎上腺素的曲线并无显著改变。猫预先注射利血平后,其瞬膜对麻黄碱的剂量反应曲线中部(2.5毫克/公斤)被压低。在猫和大鼠的剂量-升压反应曲线中,最大也卽最后一剂麻黄碱(猫:12.5毫克/公斤;大鼠:8毫克/公斤)的反应由于快速耐受性而有所降低;但用利血平后可使这个反应较对照組显著升高。大鼠预先用不同剂量利血平后,麻黄碱快速耐受性的产生趋于延緩;并且第一剂麻黄碱的升压作用,特别是在注射利血平5毫克/公斤,3—4小时后,有增强现象。切除腎上腺对上述結果似无影响。预先灌注去甲腎上腺素也可增强第一剂麻黄碱的升压作用,但与利血平化不同,对多数大鼠,反可促进快速耐受性的产生。大鼠产生快速耐受性后,灌注去甲腎上腺素可部分...

The post-ganglionic discharges from the cervical sympathetic and the splanchnic nerves were recorded in 68 rabbits and 3 cats anaesthized with urethane or urethane and chloralose. Arterial blood pressure was also recorded in some experiments. The patterns of efferent discharge were similar among the various sympathetic nerves. A rise of blood pressure followed an increase of frequency of discharges of the sympathetic, and a fall followed a decrease, with a lag of about 1-3 seconds. A single...

The post-ganglionic discharges from the cervical sympathetic and the splanchnic nerves were recorded in 68 rabbits and 3 cats anaesthized with urethane or urethane and chloralose. Arterial blood pressure was also recorded in some experiments. The patterns of efferent discharge were similar among the various sympathetic nerves. A rise of blood pressure followed an increase of frequency of discharges of the sympathetic, and a fall followed a decrease, with a lag of about 1-3 seconds. A single stimulus applied to the central stump of the cervical or abdominal vagus or of the carotid sinus nerve induced, after a short latency, a phase of augmentation of discharges lasting for 0.07-0.15 second, and then followed by a diminution of discharge. But the stimulation of the sciatic nerve and of the depressor nerve of the rabbit usually only induced an inhibition of the efferent sympathetic discharge. When the afferent fibres of peripheral nerves were stimulated with low frequency repetitive shocks, grouping of the efferent sympathetic discharges synchronous with the rhythm of the stimulus could be observed. In the rabbit, during vagus and sinus nerve stimulation the highest frequency was 10 to 13 per second, but when the somatio and the depressor nerves were stimulated, the highest frequency was only 3 to 5 per second. Repetitive stimulation of the aortic nerve of the cat only induced continuous sympathetic activity, but when the aortic nerve and the sciatic nerve were stimulated simultaneously, synchronization of the efferent bursts with the rhythm of the stimuli could be obtained. Low frequency stimulation of the pressor area in the medulla also induced bursts of the sympathetic discharge synchronized with the frequency of stimulation. Efferent sympathetic discharges were first inhibited by stimulating the depressor area at the obex, but discharges synchronous with stimulus gradually appeared later in spite of the stimulation.

颈上交感神经与内脏神经的传出冲动表现同相变化,冲动群互相同步,冲动的幅度与频率变化和动脉血压的变化相呼应,但内脏神经对传入刺激的反应较之颈上交感神经更为明显。以单个电刺激作用于迷走或颈动脉窦神经向中端,可诱发交感传出冲动呈兴奋——抑制双相反应。如给予重复电刺激,交感冲动群发放的频率变成与刺激的频率同步,其最高频率可达每秒10—3次。更高频率时,不再表现规律性,转为连续的发放。停止刺激后,有后抑制现象。重复电刺激家兔减压神经或猫和兔的坐骨神经,能完全抑制交感神经干的冲动发放。同样,重复电刺激猫主动脉弓附近神经小枝时,引起交感干持续、强烈的冲动发放。如同时刺激猫的主动脉弓处神经小枝及坐骨神经,则在一定的刺激频率下,交感冲动亦与刺激同步,最高可达7—8次/秒。以重复电刺激直接作用于延髓加压区,可得到良好的交感传出冲动节律同步的反应。刺激闩都附近可完全抑制交感传出冲动,但长期刺激下,能在抑制下释放出来,表现与刺激节律同步的冲动发放,以上两种同步的最高频率亦可达10—13次/秒。在延髓以上水平切断脑干,不影响上述机能;在闩部前方切断脑干,交感冲动大部分消失,也不能再产生反射性变化。以上结果说明,在刺激迷走和窦神经时所引...
