电刺激隔神经中枢端对家兔血管紧张素Ⅱ及肾神经传出放电的影响

EFFECTS OF ELECTROSTIMULATION OF THE CENTRAL ENDS OF PHRENIC NERVES ON PLASMA ANGIOTENSIN Ⅱ AND RENAL NERVE DISCHARGES IN RABBITS

膈神经是一混合神经，电刺激其中枢端可引起动脉血压下降．在降压反应发生后１ｍｉｎ，取静脉血测血浆血管紧张素Ⅱ（ＡＮＧⅡ）水太平降低（Ｐ＜０．０５），肾神经传出放电减少（Ｐ＜０．０１）．

The electrostimulation of the central ends of phrenic nerves elicited the depressor re-sponse in anesthetized rabbits. The depressor response was accompanied by a significant inhibitionof the angiotensin Ⅱ(ANG Ⅱ)and renal nerve discharge(RND).These results indicate that thephrenic afferents play a role in the regulation of arterial blood pressure.
