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...

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。

The experiments and observations were carried out in the laboratory in 1980—1981 on more than 30 insect species of different orders and families (11 orders & 17 families) , to test the rate of tracheal respiration during different dcvelopmental stages and metabolic activities, by using the automatic CO_2-recording equipment—Infrared Gas Analyzer(manufactured by Beijing Analytical Equipment Faetory). The aim of this research is to determine the general patterns of insect respiratory rhythms under different physiological conditions in order to evaluate the practical usages of these important physiological indexes. The preliminary results obtained are as follows:(1) The patterns of respiratory rhythm-waves for continuous recording of CO_2 outpttt through the tracheal system under the regulation of spiracles can be distinguished into 4 types, namely: (a) variable-amplitude oscillated type; (b)constant-amplitude oscillated type; (c) periodical burst type; and (d) periodical short-time spiracle-closed type. (2) The adults of the black cutworm(Agrotis ypsilon), large black cutworm (Agrotis tokionis), and cotton bollworm (Heliothis armigera), and also the summer-diapausing larvae of large black cutworm, all exhibit genetically daily respiratory rhythms during night(circadian rhythm or biological clock), which are not influenced by environmental factors even by clipping off the wings of moths.This may be a general phenomenon in insects, at least of the Family Noctuidae (Order Lepidoptera).(3) When the female large bagworm moth (Clania variegata) (Family Psychidae) releases sex pheromone at night,there is also a conspicuous burst of CO_2 output, which can be used to determine the duration of pheromone-releasing period.( 4 )The various activities of insects including the histolysis and reorganization of tissues and organs during metamorphosis, the initiation and termination of diapause, the reorganization and maturation of muscle fibers during the pharate adult stage and the teneral period for adult flight,and muscle activities during wing-beat preparing for fly and also during the regular flight,etc., all cause conspicuous corresponding changes of the respiratory rhythms. These rhythm changes can be used as physiological indexes for practical use. (5) The results of mimic water-submerged tests for the cotton bollworm during its pupal stage indicate that the changes of the respiratory chythm waves can be used to determine the best period and duration for submerging the pupae so as to obtain the highest mortality in the fields.

本试验用红外线CO_2分析仪对多种昆虫的呼吸进行了测试。目的在于研究不同种类的昆虫在不同虫态或各种活动期的呼吸代谢规律性,并探讨其实用价值。初步试验结果表明,昆虫经气管系统和气门开闭机构释放CO_2的方式,分为四种类型:(1)不规则波动型,(2)等幅波动型,(3)周期爆发型,(4)周期间歇型。用小地老虎,大地老虎及棉铃虫等昆虫测试的结果,都表明夜蛾科成虫及大地老虎滞育幼虫,在晚间有明显的、不受环境因素影响的呼吸日节律;大袋蛾雌蛾在释放性信息激素时,也有明显的CO_2释放波峰。昆虫的一切活动,包括发育变态期中器官的解离和组合,滞育期的开始和终止,飞行预备期中翅肌的生长和成熟,以及启动和持续飞行等活动,都发生明显的呼吸节律变化。这些变化,均可作为生理变化的指标而加以应用。

The experiments were carried out on 53 unanaesthetized,vagotomized,para-lyzed and artificially ventilated rabbits.The effects on phrenic discharges indu-cted by electrical or chemical(strychnine)stimulation applied to the contralateralsensorimotor cortex Consisted of two responses.The first response of phrenic dischargesappeared immediately after Stimulation.It was manifested as a burst of dischargesduring expiratory phase or a depression of discharges during inspiratory phase.Electricalstimulation more effectively...

The experiments were carried out on 53 unanaesthetized,vagotomized,para-lyzed and artificially ventilated rabbits.The effects on phrenic discharges indu-cted by electrical or chemical(strychnine)stimulation applied to the contralateralsensorimotor cortex Consisted of two responses.The first response of phrenic dischargesappeared immediately after Stimulation.It was manifested as a burst of dischargesduring expiratory phase or a depression of discharges during inspiratory phase.Electricalstimulation more effectively induced a depression but chemical stimulation more easilyresulted in an excitation.Tractotomy experiments revealed that the corticospinaland cortico-rubro-spinal tracts were the nervous pathways of the first response.Whether the stimulation was applied to the inspiratory or expiratory phase,thesecond response of phrenic,discharges was consistently an acceleration ofspontaneous respiratory rhythm.When the phrenic discharges and respiratory unitdischarges of the nucleus tractus solitarius were recorded simultaneously,thesecond responses would appear concomitantly.Section of the cortico-spinal andcortico-rubro-spinal tracts did not affect the second response.This revealed thatthe second response,was mediated by the brain stem respiratory centersindirectly.

在53例清醒、肌肉麻痹、切断迷走神经的家兔,刺激对侧皮层感觉运动区引起膈神经上的放电效应包括两种不同成分。第一效应指紧接刺激发生的放电变化。在呼气相刺激时,第一效应表现为短暂的放电;在吸气相刺激时,则表现为放电的抑制。士的宁刺激较易在呼气相引起第一效应,电刺激较易在吸气相引起第一效应。在 C_2切断同侧背外侧束可使第一效应消失,提示第一效应经皮层脊髓束和皮层红核脊髓束下行。第二效应指刺激后呼吸周期放电的变化。不论是在呼气相或吸气相刺激,第二效应均表现为吸气放电的提前出现、吸气时程和呼气时程的缩短。同时记录延髓孤束区单位放电与膈神经放电时,两者放电均有表现一致的第二效应。在 C_2切断同侧背外侧束,不影响第二效应的出现;完全切断同侧脊髓,则膈神经放电消失,但不影响孤東区的第二效应。以上结果说明,皮层控制膈运动神经元有两条途径,一条是皮层直接下达脊髓的途径,另一条是间接通过脑干呼吸中枢下达脊髓的途径;皮层直接下达脊髓的通路,既可兴奋也可抑制膈运动神经元的活动。
