摘要: The finding that some opioid-mediated forms of stress-induced analgesia are antagonized by hypophysectomy and dexamethasone has led to the suggestion beta-endorphin, released from pituitary, may mediate these analgesic reactions. "Long-term analgesia" (an form analgesia), which is blocked hypophysectomy, was also adrenalectomy reinstated with corticosterone therapy. Corticosterone proposed play a permissive role in long-term be critical hormone mediating this phenomenon.
