Abstract
Aim: To study the therapeutic effect of acupuncture on acute visceral pain and provide scientific evidence for clinical treatment with acupuncture. Methods: Acute visceral hyperalgesia model was established by intracolonic instillation of acetic acid. Acute visceral pain was evoked by colorectal distention (CRD). Both abdominal withdrawal reflex (AWR) and rectus abdominis electromyogram (EMG) in response to acute visceral pain were used to assess the effect of acupuncture on acute visceral pain in model rats. Results: The scores of AWR and spike-counters of EMG significantly increased in the model rats after different strength of CRD stimulation. Such increases in AWR scores and EMG spike-counters significantly decreased after the model rats received electroacupunctare treatment. Under the CRD stimulation of 40 mmHg, the scores of AWR in the electroacupuncture group were 1.29 ± 0.96, which significantly decreased as compared with those in the model group (2.86 ± 0.79). And the EMG in the former also changed (160.65 ± 82.13)%, significantly lower than that in the latter[(442.57 ± 195.01)%] (F = 8.0-62.5, P < 0.001). Conclusion: Electroacupuncture treatment can relieve acute visceral pain in model rats.
