摘要
用电生理学方法,研究了在分别切断脾俞穴主要神经通路后,电针脾俞穴对胃电运动影响的外周神经作用途径。结果表明:1电针脾俞穴对胃电有双向调节效应,电针对胃电频率和振幅影响非常显著;2切断脾俞穴主要传入节段的脊神经背根与中枢的联系后,电针对胃电频率虽仍有明显影响,但对胃电振幅无影响;3切断肋间神经后,电针对胃电频率的影响明显减小,对胃运动影响较小;4切断腹腔肠系膜前神经节所有节后纤维,电针前后胃电频率、振幅变化无统计学意义;5切断T8～T12脊神经背、腹根、肋间神经后,电针脾俞穴对胃运动有双向调节作用,电针前后胃运动频率的差异显著。证明在电针脾俞穴对胃功能的调节过程中,除中枢途径外,还存在以交感神经节为中心的中枢外反射弧途径。
The paper studied the influence of electro-acupuncturing spleen point on the gastro-electrical activity and its peripheral nerve mechanism with electro-physiology method under different conditions.The result was as following:① The amplitude and frequency of GEA of pre-post electro-acupuncture was notably different (P<0.05,P<0.01) from that of the center nervous system (CNS).② The frequency of GEA of pre-post electro-acupuncture was still notably different (P<0.01) while the amplitude of GEA (GEAA) had no change (P>0.05) when the connection of spleen point to DRG had been cut.③ The frequency of GEA of pre-post electro-acupuncture was different (P<0.05) when the intercostale nerves were cut.④ The varies of amplitude and frequency of GEA of pre-post electro-acupuncture had no statistic meaning (P>0.05) when the celiac and anterior-mesenteric was cut.⑤ After cutting the T_8-T_(12) spinal nerver dorsal roots and ventral roots and intercostales,the gastro-activity was regulated bidirectionally and notably by electro-acupuncturing the spleen point.The results suggest that there was a reflex arc outside the CNS though CNS was very important during the course of spleen point effecting GEA.The afferent fiber of spleen point was intercostal nerves and the efferent fibers was sympathetic nerve,the sympathetic ganglion was important in the ref1ex-arc outside the CNS.
