Bilateral cervical vagotomy prolonged the latent period ( P < 0.01) but reduced the excitatory and inhibitory periods ( EP, IP) and the duration enduring asphyxia during asphyxia ( P < 0.01). 切断迷走神经后窒息潜伏期延长,兴奋期、抑制期和耐受窒息时间缩短(P<0.01)。
This inhibitory effect of NT was completely blocked by icv pretreatment with the α-adrenergic receptor antagonist phentolamine or after bilateral cervical vagotomy, suggesting that the effect may be related with activation of α-adrenergic receptors in the nucleus and mediated by vagal nerves. 这提示,PVN注射NT对大鼠胃酸分泌的抑制作用,可能与该处α-受体的激活有关,并通过迷走神经所中介。
The effect of pulmonary surfactant replacement on acute lung injury induced by bilateral cervical vagotomy in guinea pigs 肺泡表面活性物质对豚鼠迷走神经性肺损伤的治疗作用
The bradycardiac effect was significantly attenuated by bilateral vagotomy ( P < 0.01). 双侧迷走神经切断后,降心率作用减弱(P<0.01)。
