Abstract
AIM:To observe the changes of colonic propulsive movement in rats after high-frequency electroacupuncture stimulation (EAS) at Zusanli (ST-36).
METHODS: A total of 33 adult male Sprague-Dawley rats were randomly and averagely divided into Zusanli acupuncture, sham EAS, and Zusanli EAS group, named A, B, and C, respectively. The parameters of EAS were set at 100 Hz, 3 mA. In the experiment, one plastic bead (3 mm in diameter) was pushed 3 cm into the rats’ rectum with a slender tube, and the time for bead excretion was recorded in all the rats.
RESULTS: The time for bead excretion under EAS condition was shortened about 27% in group C as compared with that under normal condition, and there was significant difference (1142.8 ± 123.9 s vs 1563.5 ± 155.9 s, P < 0 ......
