[Hormonal nature of long-term reactions of cerebral vessels to stimulation of cervical postganglionic sympathetic fibers].
In anesthetized cats, single unilateral electric shock applied to the postganglionic cervical sympathetic pathway induced a decrease of cerebral flow for 45--90 min in parietal region by 21.7 +/- 0.9% in the gray matter and by 51.3 +/- 1.2% at the boundary of the gray matter. The systemic arterial pressure remained constant. The cerebral oedema occurred on the stimulated side. These reactions seem to be due to vasopressin participation.
