| Outline of Final Research Achievements |
We investigated whether intra-venous corticotropin releasing hormone (CRH) administration increases esophageal sensitivity by electrical stimulation in healthy subjects and NERD patients. To evaluate electrical sensitivity, an electrode was inserted and placed above the upper boarder of the lower esophageal sphincter (LES). The electrical stimulation was gradually increased. We quantified the initial perception threshold (IPT: the minimum current intensity at which the subject first perceived the stimulus). After determination of the baseline IPT, we intravenously administered CRH. As a result, CRH significantly decreased electrical threshold of the esophagus after CRH injection in both healthy subjects and NERD patients, thus suggesting that CRH increased esophageal sensitivity to the electrical stimulus.
