Acupuncture Points Are Different
A study was conducted to investigate the distribution of monoamine transmitters at
acupoints and effect of acupuncture on it. Take this experiment by means of
microdialysis. Twenty rabbits were randomly assigned to two groups (Group A: acupuncture
Guanyuan (RN4), Group B: acupuncture nonacupoint which is besides Guanyuan
(RN4) 1 cm). Before and after acupuncture was taken, tissue fluids both at
Zhongwan (RN12) which is on the same meridian as Guanyuan and at a nonacupoint
1 cm away from Zhongwan were collected through microdialysis, respectively. The
collected samples were analyzed to determine concentrations of monoamine
transmitters. Epinephrine and 5-HT were detected. An unknown substance was
found. Its concentration at acupoint was significantly higher than that at
nonacupoint and decreased after acupuncture. Its significant specificity at
acupoints suggests that it may play an important role in meridian's activity.
