Abstract

With the use of potassium iontophoresis induced tail-flick for measuring the pain threshold, the effects of injecting neurotensin (NT), naloxone (NX), anti-metenkephalin serum (AMEKS), anti-#beta#-endorphin serum (AEPS) and anti-dynorphin A_(1-13) serum (ADYNS) into periaqueductal grey (PAG) on electroacupuncture (EA) analgesia in rats were investigated.

Key words: Neurotensin;Periaquedutal gray;Electroacupuncture analgesia; Antimetenkephalin serum;Antiendorphin serum;Antidynorphin A_(1-13) serum;
