Abstract

|
Objectives: The aim of this study was to observe the effect of acupuncture and high frequency electroacupuncture at ST39 on intestinal motility in rats.
Methods: We made over-activated state of intestinal motility with carbachol and suppressed state of intestinal motility with loperamide in rat and carried out needle retention acupuncture and high frequency electroacupuncture at ST39 or sham point in rat divided into pre-treatment group and post-treatment group. We fed charcoal to them after the treatment and measured the travel rate of charcoal in the gastrointestinal tract to observe intestinal motility.
Results: Examining intestinal motility of normal rat treated with needle retention acupuncture at ST39 significantly suppressed intestinal motility. Pre-treatment of needle retention acupuncture significantly suppressed intestinal motility in rat which over-activated with carbachol. Pre-treatment and post-treatment of high frequency electroacupuncture significantly suppressed intestinal motility in rat which over-activated with carbachol. All of the pre-treatment and post-treatment of needle retention acupuncture, high frequency electroacupuncture showed no significant effect than control group on intestinal motility of rat which was suppressed with loperamide.
Conclusions: These results suggest that acupuncture and high frequency electroacupuncture at ST39 have preventive and therapeutic effects on over-activated intestinal motility, and high frequency electroacupuncture is more effective.
