sinus nerve

Experimental study of carotid sinus nerve block in prevention and treatment of hemodynamics instability caused by carotid sinus stimulation

以窦神经阻滞防治由颈动脉窦刺激引起的血液动力学紊乱的实验研究

METHODS : The functional curve of carotid baroreceptor ( FCCB ) was constructed and the functional parameters of carotid baroreceptor were measured by recording sinus nerve afferent discharge in anesthetized male rats with perfused isolated carotid sinus .

方法：在麻醉雄性大鼠隔离灌流颈动脉窦条件下记录窦神经传入放电，观察17β-雌二醇（E2）对压力感受器机能曲线和机能参数的影响。

The results showed that the nicotinic acetylcholine receptor ( nAChR ) antagonists , mecamylamine and hexamethonium , abolished both spontaneous activity and hypoxia induced spike discharge recorded extracellularly from the intact rat carotid body sinus nerve preparations in vitro .

结果发现胆碱能N受体（nAChR）阻断剂mecamylamine和hexamethonium抑制离体颈动脉体-窦神经标本细胞自发放电及缺氧诱发电位。

And the lateral structures of middle clivus were composed of petrous internal carotid artery , inferior petrous sinus and abducent nerve ;

中斜坡侧壁重要结构有颈内动脉岩骨段、岩下窦和外展神经经过的Dorello管，循翼管向后方可安全确认颈内动脉岩骨段；

Pattern Visual Evoked Potential ( PR-VEP ) was examined before damage . Through the nasal cavity sieve and sphenoid sinus , optic nerve of the pipeline was damaged by the injury tool which was made by ourselves .

经鼻腔筛蝶窦入路，用自制视神经管损伤器损伤管内段视神经，建立TON模型，检测图形视觉诱发电位（PR-VEP），观察动物瞳孔对光反应。

The length of sphenoid sinus in the optic nerve was 8.28 ± 4.09 mm .

外侧壁段的视神经长径为8.28±4.09mm。

Its functional mechanism is that Na-citrate has stimulated the carotid sinus through the vagus nerve to the respiratory centre .

其作用机理是枸橼酸钠刺激了颈动脉窦区感受器，通过迷走神经传入呼吸中枢引起的。

The effect of agmatine ( Agm ) on the carotid baroreceptor activity was examined in 24 anesthetized rats with perfused isolated carotid sinus by recording sinus nerve afferent discharges .

在麻醉大鼠隔离灌流颈动脉窦区条件下，记录窦神经传入放电，观察胍丁胺（agmatine，Agm）对动脉压力感受器活动的影响。

In the one third of inferior of lateral wall of sphenoid sinus , the length of sphenoid sinus in the maxillary nerve was 8.3 ± 3.24 mm .

蝶窦外侧壁下1/3处壁前后径为14.75±3.12mm；外侧壁段的上颌神经长径为8.3±3.24mm。
