| Research Abstract |
Pain is one of the physical stressor for humans. In this study, we performed quantitative analysis of CRF gene transcription in hypothalamic PVN under the condition of tongue pain stress in rats. Plasma adrenocorticotropic hormone (ACTH) secretion was peak at 30 min after the capsaicin injection to tongue prior to gradually increasing of plasma corticosterone, indicating that tongue pain is stressor enough to up-regulate hypothalamo-pituitary- adrenocortical axis. CRF hnRNA 15 min after the injection was up-regulated 3 fold than that of control rats. This report is the first study which succeeded to detect CRF hnRNA by quantitative real-time PCR analysis.
