Regulative effect of electroacupuncture of different frequencies on derangement of gastric electric rhythm in rabbits / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To investigate regulative effect of electroacupuncture (EA) of different frequencies on derangement of gastric electric rhythm in rabbits.</p><p><b>METHODS</b>Derangement of gastric electric rhythm model was made with injection of erythromycin into ear vein in 40 rabbits, and randomly divided into a model group, a 3 Hz-EA group, a 20 Hz-EA group and a 100 Hz-EA group. They were treated with EA at Zusanli (ST 36) with 3 Hz, 20 Hz and 100 Hz, respectively. PDP and PTP at different periods were detected with IEGG spectrum analyzer.</p><p><b>RESULTS</b>Erythromycin could significantly enhance PDP and PTP values in the rabbit (P < 0.001). PDP and PTP values were reduced significantly after EA with 3 Hz, 20 Hz and 100 Hz (P < 0.05), with no significant differences in effect on PDP among them (P > 0.05); therapeutic effect of the EA of 20 Hz on PTP was better than that of 3 Hz (P < 0.05), with no significant difference as compared with the EA of 100 Hz.</p><p><b>CONCLUSION</b>EA of the 3 frequencies shows significantly different regulative effects on derangement of gastric electric rhythm in rabbits.</p>
