刺激兔颈交感神经节及椎动脉对血压影响的实验观察

了解颈椎及其周围的软组织与颈椎性血压异常的关系，探讨颈椎性血压异常的发病机理。方法以健康大耳白兔５０只，暴露双侧颈前及颈后交感神经节和椎动脉，直接给予牵拉、压迫、电刺激、并用电动记纹鼓记录刺激前、后股动脉的血压变化。结果压迫牵拉刺激使兔的动脉血压变化较大，电刺激使动脉血压变化较小；

Experimental Study of the Effects of Stimulating Cervical Sympathetic Ganglia and Vertebral Artery of the rabbits on Blood Pressure

Objective:This study is designed to explore the relationship between cervical dysarteriotony and the adjacent cervical soft tissues,so as to delineate the mechanism of cervical dysarteriotony Methods:50 healthy rabbits'sympathetic ganglia and vertebral artery were stimulated directly by pulling,compressing and electric stimulation Then blood pressure(BP)changes were recorded before and after the stimulations with electric cymograph Results:The rabbits'BP changed considerably by compression and pulling stimulation and changed slightly by electric stimulation After the above stimulations on the rabbits anterior cervical sympathetic ganglion,their BP had a tendency lowering down With the same stimulation on the posterior cervical sympathetic ganglion,their BP had a clear tendency lowering down With the same stimulation on the vertebral artery,their BP were changed slightly Conclusion: The BP goes up or steps down by the same stimulation applied on different areas The results of the observation not only have provided the reference basis for the clinical experiment,but also have added reference data for the establishment of animal model of this condition
