The application of a painful stimulus to restrained rats provokes conspicuous adrenovascular alterations (vasodilatation, edema, small hemorrhages). Hypophysectomy does not prevent the adrenovascular response to stress, or the abdominal vagotomy. On the contrary, splanchnicotomy practically abolishes such response. These results show that the vascular alterations, consequence of the action of a neurogenic stress, are not caused by a hypophysohormonal response but by a sympathetic one.
对受束缚的大鼠施加疼痛刺激会引发明显的肾上腺血管改变（血管舒张、水肿、小出血）。垂体切除术并不能阻止肾上腺血管对应激的反应，也不能阻止腹部迷走神经切断术。相反，内脏神经切断术实际上消除了这种反应。这些结果表明，作为神经源性应激作用结果的血管改变，不是由垂体激素反应引起的，而是由交感神经反应引起的。
