| Research Abstract |
Many questions about the context of the nociceptors and masseter muscle activity and acid reflux into the esophagus, we focus on the nociceptors In this study, we loaded with acid-pepsin stimulation to rat esophageal mucosa, infringement and masseter muscle activity We investigated the enhanced expression of receptors. Was injected saline, the acid pepsin solution in Wister male rats, were examined for nociceptors esophagus and masseter muscle activity. Masseter muscle activity, expression of nociceptors was significantly in acid pepsin solution group. From this result, esophageal irritation of acid-pepsin is transmitted to the central by the activation of the vessel, likely to be involved in masseter muscle activity can be considered, masseter muscle activity is induced by acid-pepsin exposure to road , it was suggested to be associated with nociceptors in the esophagus.
