牵拉颈上交感神经节对家兔血压及血清去甲肾上腺素含量的影响

Blood pressure and serum norepinephrine after stretching the superior cervical sympathetic ganglia

目的探讨牵拉颈上交感神经节对家兔血压和血清去甲。肾上腺素含量影响的相关性。方法对10只家兔进行牵拉颈上交感神经节模拟颈源性高血压的物理刺激，观察牵拉前、后家兔平均动脉压及血清去甲。肾上腺素含量的变化，并分析两者变化之间的相关性。结果牵拉颈上交感神经节后，家兔平均动脉压为（100．74±1．54）mmHg，血清去甲肾上腺素含量为（194．77±9．68）mmHg，分别与牵拉前的（87．01±1．92）mmHg和（155．26±6．88）mmHg比较，差异均有统计学意义（P〈0．01）。经统计学分析，牵拉前、后家兔血压变化与血清去甲肾上腺素含量变化呈显著相关。结论牵拉颈上交感神经节与家兔血压和血清去甲肾上腺素含量显著相关。

Objective To investigate the changes in blood pressure and serum norepinephrine after stretc- hing the superior cervical sympathetic ganglia. Methods The superior cervical sympathetic ganglia of 10 rabbits were stretched to simulate the physical stimulation of cervicogenic hypertension. The blood pressure and content of norepinephrine in serum were observed and the observations were correlated. Results The rabbits＇ blood pressure had risen significantly after the stretching. The content of norepinephrinc in serum had also increased significantly. The changes in blood pressure and norepinephrine content showed significant correlation. Conclusion The changes in blood pressure and serum norepinephrine after stretching of the superior cervical sympathetic ganglia show signifi- cant correlation, at least in rabbits.
