[Hypertension by nerve section in adrenalectomized, hypophysectomized, thyroidectomized and splanchnectomized dogs or in dogs with diabetes insipidus].

In the dog under anesthesia by pentobarbital, the acute hypertension by depressor buffer nerves section does not develop after adrenalectomy, hypophysectomy or thyroïdectomy. But this type of acute pressor response does appear normal in the dog parathyroïdectomized, splanchnicectomized or with hypothalamic diabetes insipidus.
