Abstract
|
|
|
The pain was induced on upper and lower incisor of the rat based on the theory of ’connections of upper incisor pain with stomach meridian and lower incisor pain with large intestine meridian’. Such acupoints as LI4 and ST36 were used for alleviation of upper and lower incisor pain. The digastric myogram (dEMG) was utilized for the pain measurement.
The upper incisor pain was gradually decreased during ST36 stimulation and significant differences were observed at 20 minutes point during 60 minutes study. The upper incisor pain was gradually decreased during LI4 acupuncture and 20 minutes point was the only point that showed a significant difference. The alleviation of lower incisor pain was not obvious during the ST36 acupuncture. The lower incisor pain was gradually decreased during LI4 stimulation with significant differences at 20 and 40 minutes point. In conclusion, the upper incisor pain was relieved with LI4 and ST36 acupuncture while LI4 was effective on the lower incisor pain alleviation based on the theory of ’connections of upper incisor pain with stomach meridian and lower incisor pain with large intestine meridian’.
