胃节律紊乱

系胃功能性疾病。它的出现可能是胃肠道疾病的早期表现

也可能是胃肠道以外某些全身性疾病通过神经或体液因素在胃部的反应。据文献报道

用药物引起的胃节律紊乱类似自发性的胃节律紊In fasting and anaesthetic rabbits

the experimental model of gastric dysrhythmia could be produced by electric stimulation of inferior phrenicus vagus and splanchnic nerve for innervation of courpus and antrum

or by left gastric artery infusion of Adr

Ach and glucacon at a steady vilocity. The results were as follows. (1) Electrical stimulation of inferior phrenicus vagus at low frequency and intensity could increase the frequency and amplitude of basic electric rhythmia (BER) or slow wave (P<0.01)

and might induced tachygastria and tachyarrthythmia. Electrical stimulation of splanchnic nerve could increase the frequency and amplitude of BER (P<0.05)

and might induced bradygastria. (2) Bradygastria cculd be elicited by left gastric artery infusion of Adr (400μg/kg/h). The frequency and amplitude of BER induced were decreased" Tachyarrhytmia could be elicited by infusion of Ach (400μg/kg/h). The frequency and amplitude of BER induced were increased. Dysrhythmia of BER could be elicited by infusion of glucagon (400μg/kg/h). (3) Electroacupuncture of "Zusanli" acupoint may exhibit double modulated effects on experimental model of gastric dysrhythmia. Different types of gastric dysrhythmia including tachygastria

bradygastria and tacbyarrhy thmia could turned to approach the normal gastric myoelectric activity. It is revealed that such effects of electroacupuncture may be mediated via autonomic nerve and peripheric special receptors.
