[Effect of electroacupuncture at zusanli (ST36) point in regulating the pylorus peristaltic function]

The effect of electroacupunture at Zusanli (ST36) point in regulating the human pylorus sphincter pressure was investigated in this study by means of the endoscopic manometry. The result showed: After electrostimulating Zusanli point, the amplitude of the low wave of pylorus sphincter pressure was raised and the amplitude of the high wave was reduced significantly while the amplitude of the middle wave did not reveal significant change, compared with the results of the controls and the non-acupuncture point group. It is indicated that Zusanli point may have dual effect on the regulation of the pylorus peristaltic function, which expressed itself as enhancing the hypofunction and weakening the hyperfunction of pylorus peristalsis.
