自主神经系统

Sevoflurane reduces autonomic neural control, which plays a significant role in cerebral autoregulation.

七氟醚降低自主神经系统调节，后者在脑自动调节中扮演重要角色。

With the development of lesion inautonomic nervous system, i.e. the elevation of baroreflex set point, blood pressureincreases to stage 1 hypertension and worsens. Furthermore, the role of the effectors,including PVR, ventricular end-systolic elastance, venous unstressed volumes and heartrate, in the regulation of hypertension was analyzed. The results exhibit that the ANSregulation on hypertension works mainly by the reduction of PVR and the increase ofvenous unstressed volume.

随着自主神经系统损坏程度的不断加重，即工作调定点进一步升高，血压水平上升到了1级高血压并趋于严重；研究了神经调节的各效应器(外周血管阻力、心肌最大弹性度、心率和静脉非压力容积)对高血压的作用，表明神经调节机制对高血压的调节主要是通过降低外周血管阻力和增加静脉非压力容积实现的。

Objective To study the changes of blood pressure and heart rate during vasovagal syncope and understand the effects fo auto nomic nerve system.

目的 探讨血管迷走性晕厥时血压，心率变化，从而了解自主神经系统所起的作用。

Psychological factors such as anxiety take a role in the pathology of constipation. The symptoms of anxiety disorders were related with autonomic nerve regulating function disorder, especially related with pneumogastric disorder.

焦虑等心理因素在便秘的发病中起一定作用，焦虑症状的产生可能与便秘患者自主神经系统功能异常有关，尤以迷走神经为甚。

During the past three decades, as a good marker of activities of autonomic nervous system , HRV were widely used in clinical medicine and psychophysiological studies of emotion.

近三十年来，心率变异性作为评价自主神经系统功能的良好指标已广泛用于临床医学以及情绪的生理心理学研究中。

AIM To investigate the effect of autonomic nerves on the transmural dispersion of effective refarctory period upon acute myocardium infarction in vivo.

目的 为探讨自主神经系统对在体家兔急性心肌梗死后跨室壁3层心肌细胞有效不应期离散度的影响。

Children, Atrioventricular Conduction Block, Heat Rate Variability, Autonomic Nervous System

E. FHR accelerations and mild variable decelerations are indicativeof a normally functioning autonomic nervous system.

E。胎心率减速和轻度可变减反映的是正常的自主神经系统功能。

Our results showed that DEPs may cause autonomic nervous system dysfunction in SHR.

本研究结果显示柴油引擎微粒暴露会引起自发性高血压大鼠心跳速率及心跳速率变异性的变化，可能与自主神经系统异常有关。

Quantitatively, the optical density of NADPH-d positive neurons in all of the related nuclei was significantly increased in the BDL animals compared with controls. Since NO is thought to be able to increase the motilities of the gallbladder and the sphincter of Oddi in anesthelized rabbits, the elevation of NADPH-d and NOS reactivities is likely to magnify the excitatory effect on the extrahepatic biliary system for the purpose of depletion of the loitered bile juice from the jaundiced liver. These data may also have important implications for the altered state of circulatory, metabolic or regenerative responsiveness under pathological condition.

此现象一来可推测，肝脏在遭受胆管阻塞性黄胆的伤害后，其代谢、血液动态与温度调节作用势必改变、紊乱、甚至失功能，而感觉神经也势必会接受到大量的机械性、化学性、渗透性等感知讯息，所以感觉神经元将一氧化氮制造量提升，有助於感觉讯息的快速传报，以发挥回馈调控的效果；二来可表示，自主神经系统不论是交感或副交感神经，为了因应胆管阻塞所造成肝脏的病变，以增加一氧化氮的制造，意欲刺激肝外胆道系统，排空滞留在肝脏内或胆囊内的胆汁，而达到恢复肝脏内代谢、血液循环、胆汁流动等功能控制的恒定状态。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
