Research on the Relationship between Spinal Ways and the Effect of Point Zusanli (ST 36) / 针灸推拿医学（英文版）

ABSTRACT

Objective: The integrity of the corresponding dorsal root is important in the research of the effects of acupuncture Zusanli (ST 36) on gastric smooth muscle. Investigate the communicate channels of central control on the effect of acupuncture Zusanli (ST 36). Method: Selected 30 healthy adult SD rats and using veniua-glacial acid to made gastric mucosa ulcer model. Divided them into three groups, model group, cutting L1-S1group and transecting T10-T11group after the models have been made successfully, each group 10 rats. Implanted diameter in 0.2 mm Platinum Circle electrode into subserous of the ulcer place and recorded the myoelectricity activity of gastric smooth muscle before and after acupuncture Zusanli (ST 36). Acupuncture parameters, 2-100 Hz, lasting 20 mill. Results: Model group before acupuncture, (5.73±0.51) cycle per minitue (cpm), (2.28±0.57) mV; model group after acupuncture, (5.34±0.34) cpm, (1.06±0.13). Group that before cutting dorsal L4-S1, (5.65±0.26) cpm, (1.66±0.15) mV; group that after cutting dorsal L4-S1(5.40±0.23) cpm, (1.17±0.23), group that after cutting dorsal L4-S1and acupuncture, (5.26±0.18) cpm, (2.45±0.23). Group that before transecting dorsal T10-T11, (5.69±0.36) cpm, (1.91±0.25) mV, group that after transecting dorsal T10-T11, (4.98±0.53) cpm, (1.05±0.18) mV, group that after transecting dorsal T10-T11and acupuncture, (4.60±0.44) cpm, (2.52±0.38) mV. Conclusion: Acupunture Zusanli (ST 36) can inhibit the myoelectricity activity of gastric smooth muscle, cutting L4-S1 can strengthen the myoelectricity activity, but the effect of transect T10-T11 is better. So it can be said that the integrity of Dorsal root is important to the effect of acupuncture. The two-way regulation of Acupuncture has a close relationship with the higher centre above spinal cord.
