  peripheral chemoreceptors
Abnormalities in several systems contribute to neurohumoral excitation in HF, including arterial and cardiopulmonary baroreceptors, central and peripheral chemoreceptors, cardiac chemoreceptors, and central nervous system abnormalities.
      
It represents a significant improvement of our previous work, including the effect of potassium on peripheral chemoreceptors, a fast and a slow neurogenic component, and a more accurate description of blood flow control.
      
Cardiac and ventilatory responses in both species were attributed to stimulation of central and peripheral chemoreceptors by cyanide.
      
Role of peripheral chemoreceptors in response to smoke-induced apnea vs tracheal occlusion
      
It must be emphasized that all these recent studies do not contradict at all, but rather help to explain, the early findings of Pierre Dejours concerning the participation of the peripheral chemoreceptors in the regulation and control of breathing.

(1) In the rabbit, anesthetized with urethane or chloralose and urethane, intravenous injection of ammonium chloride(25—50mg/kg) invariably induced hyperpnea. This effect still persisted after cutting the sinus, depressor, and vagus nerves. (2) In some experiments the carotid sinus area of one rabbit(recipient) was vascularly isolated and perfused by the arterial blood of another animal(donor).

(1) In the rabbit, anesthetized with urethane or chloralose and urethane, intravenous injection of ammonium chloride(25—50mg/kg) invariably induced hyperpnea. This effect still persisted after cutting the sinus, depressor, and vagus nerves. (2) In some experiments the carotid sinus area of one rabbit(recipient) was vascularly isolated and perfused by the arterial blood of another animal(donor). It was demonstrated that ammonium chloride given intravenously to the donor failed to provoke hyperpnea of the recipient, while sodium cyanide given via the same route stimulated respiration in both rabbits. (3) Intracisteral injection of ammonium chloride in a dose of 0.4—0.5mg/kg (total volume 0.13—0.14 ml) induced a marked hyperpnea. (4) From the results obtained, it seemed likely that the hyperpnea induced by intravenous injection of ammonium chloride was duo to direct excitation of the respiratory center by increase in hydrogen ion concentration of the blood, and that the peripheral chemoreceptors played no significant role in this effect.

(一)麻醉兎靜脉內注射氯化銨(25—50毫克/公斤),可規律地引起呼吸增强,这种效应在切断竇神經、减压神經和迷走神經后不变。 (二)在頸动脉竇区灌注的条件下,給供血兎靜脉內注射氯化銨并不能刺激受血兎頸动脉体化学感受器而兴奋呼吸,由此說明化学感受器对氫离子不敏感。 (三)小脑延髓池內注射小量氯化銨,可导致明显的呼吸增强。 (四)氯化銨所致的呼吸增强,可能主要是由于血浆中氫离子增加对呼吸中樞的直接刺激作用,外周化学感受器在这方面不起重大作用。

A model for perfusing the carotid boby (CB) in the awake goat was described indetail. The main surgical procedures were: (1) to ligate the occipital artery, cut thecarotid sinus nerve and excise the CB on one side; (2) to rearrange some arteries,which supply the brain and neck on the other side (perfusion side), for isolating theCB; (3) to place cannulae in the jugular vein and the carotid artery for drawing bloodand perfusing the intact CB on the perfusion side. Perfusion of the CB with goat ownblood can be...

A model for perfusing the carotid boby (CB) in the awake goat was described indetail. The main surgical procedures were: (1) to ligate the occipital artery, cut thecarotid sinus nerve and excise the CB on one side; (2) to rearrange some arteries,which supply the brain and neck on the other side (perfusion side), for isolating theCB; (3) to place cannulae in the jugular vein and the carotid artery for drawing bloodand perfusing the intact CB on the perfusion side. Perfusion of the CB with goat ownblood can be carried out via an extracorporal circuit during the experiment. The remarkable advanages of this perfusion model are: (1) the animal can be kept in a normalphysiological condition; (2) the arterial gases and pH in the CNS and CB can be controlled separately. The NaCN test was done in three steps to evaluate the model by judging the sensitivity of the peripheral chemoreceptors including the aortic and perfusedcarotid bodies. Applications of this model were also discussed.

本文对清醒山羊颈动脉体灌流模型作了详细介绍。手术步骤包括:(1)在颈部任一侧结扎枕动脉、切断窦神经及切除颈动脉体;(2)完成对供应另一侧(灌流侧)脑和颈部血管的改道手术,以便从血液供应上游离颈动脉体;(3)在灌流侧安置颈静脉插管和颈动脉插管,建立灌流通路。实验中应用体外循环方法以动物自身血液灌流颈动脉体。该模型具有两个显著优点:(1)实验中可保持动物处于正常生理状态;(2)对脑组织和颈动脉体的血液血气及pH能分别加以人为控制。实验前动物均经过氰化钠试验检查颈动脉体和主动脉体的化学敏感性,用以评价灌流模型的有效性。文中还对这一模型的应用进行了讨论。

It is well known that the ventrolateral medulla oblongata plays an important role in regulating respiratory and cardiovascular systems. In the vetrolateral medulla oblongata area there are two important vasomotors, namely rostral and caudal vasomotors. The chemoreceptors incorporating respiratory regulation is located in the superficial part of ventrolateral medulla oblongata, which is also involved in the integration of afferent input from both the central and peripheral...

It is well known that the ventrolateral medulla oblongata plays an important role in regulating respiratory and cardiovascular systems. In the vetrolateral medulla oblongata area there are two important vasomotors, namely rostral and caudal vasomotors. The chemoreceptors incorporating respiratory regulation is located in the superficial part of ventrolateral medulla oblongata, which is also involved in the integration of afferent input from both the central and peripheral chemoreceptors. Briefly reviewed were some paramount controversial issues. 

现已知延髓腹外侧区在呼吸调节和心血管调节中起着重要作用.延髓腹外侧区有两个重要的血管运动中枢,称为头侧和尾侧血管运动中枢.参与呼吸调节的中枢化学感受器位于延髓腹外侧区浅表部位;延髓腹外侧区还参与中枢和外周化学感受器的传入冲动的整合.文章对一些最重要的有争论的观点作一综述
