Abstract

The changes of pain threshold and two neuropetides, substance P (SP) and methionine-enkephalin (ENK), were observed after He-Ne laser irradiating at acupoint(LIA) of rats. The pain threshold was very significantly higher after LIA than before (P<0.001). The SP-LI was obviously enhanced (P<0.001), whereas the ENK-LI markedly diminished (P<0.001) in the rats of laser group as compared with those of control group.
