摘要
本文观察麻醉情况下,侧脑室及耳静脉注入5羟色胺(5-HT),家兔颈动脉血压及肺动脉压的变化。结果发现,耳静脉注入5-HT(100 μg/20 μl)后,肺动脉压上升,颈动脉血压下降,侧脑室注入5-HT后,肺动脉压和颈动脉血压的反应与耳静脉注入柑反。侧脑室注入5-HT引起的肺动脉压及颈动脉血压的变化有阿片样肽类物质的参与;肺动脉压反应还与迷走神经传导及乙酰胆硷的作用有关。
The change of Psa and Ppa was observed during injection of 5-HT into the lateral ventricle of brain or the auricular vein of anesthetized rabbits. Increase of Ppa and decrease of Psa were found after injection through auricular vein. On the contrary, while 5-HT was injected into lateral ventricule there were increased of Psa and decreased of Ppa. The responses of Ppa induced by 5-HT injecting into lateral ventricle might be related to the transmission of vagus and the action of Ach. The opiumnoid substances might take part in the change of Ppa and Psa while 5-HT was injected into lateral ventricle of brain.
