In anaesthetized cats, electrical stimulation within the fore-brain defence areas evoked a marked increase in the plasma level of immunoreactive beta-endorphin which reached a peak after 5 minutes. Multiple immunoreactive peptides including "biologically-active" beta-endorphin-(1-31) were detected. It is suggested that the release of pituitary beta-endorphin during emotional stress results from the natural activation of the defence areas.
在麻醉猫中，刺激前脑防御区域会引起免疫反应性β-内啡肽血浆水平显著升高，5分钟后达到峰值。检测到多种免疫反应性肽，包括“生物活性”β-内啡肽-（1-31）。有人提出，情绪应激期间垂体β-内啡肽的释放是防御区域自然激活的结果。
