Objective: To study effect of acupuncture on pH values of acupoints and non-acupoints.
Methods: The pH values of acupoints and non-acupoints were determined with pH sense needles at the same time and separately in the goat.
Results: (1) The pH value of the acupoints and non-acupoints decreased when acupuncture was separately at acupoints and non-acupoints with the pH value of the acupoint decreased more significantly; (2) there was no significant difference in decreasing amplitudes of the pH values between the acupoint and non-acupoint when acupuncture was simultaneously given at acupoints and non-acupoints.
Conclusion: Acupuncture can more significantly strengthen metabolism of acupoints; when acupuncture was simultaneously given at acupoints and non-acupoints, local metabolism is influenced each other.
