[Effect and nervous mechanism of acupuncture on gastroelectrical propagation velocity]

Zhang H, Wan DM, Zhang ZX.

20 fasting cats were used to investigate the propagation of Gastroelectrical Propagation Velocity (GPV) and the effect and nervous mechanism of acupuncture on it. The results are as follow: 1. GPV can be described as V = bo - b1x1 + b2x2. bo, b1 and b2: regression coefficient. x1: frequency of slow-wave. x2: amplitude of slow-wave. 2. GPV is changeable on normal condition, and it can be affected by stimulation of vagi or splantic nerve and by administration of pentagastrin i.v. or atropine i.v. with some change of not only x1, x2 but also b0, b1, b2. 3. Manual acupuncture and electrical acupuncture can affect GPV differently. 4. After vagotomy the effect of manual acupuncture on GPV was changed. All results suggest that GPV can be affected by acupuncture with complex mechanism including the change of propagation resistance and of propagation refractory period.
