[Correlation between acupoint sensitization of body surface and pituitary adenylate cyclase activating polypeptide expression in myocardial ischemia mice].

ISO injection resulted in histological lesions and cardiogenic referred pain on the body surface after the formation of MI in mice. The expression of PACAP in the body surface of the sensitization points, the corresponding T1-T5 segments of spinal cord and DRG neurons were significantly increased, which may partly explain the reason for acupoint sensitization in the animal model of visceral pain.
