The goal of this study was to determine whether increases in cerebral venous pressure
contribute to, and may account for, disruption of the blood-brain barrier during acute …

The purpose of this study was to examine hemodynamic mechanisms of protection of the
blood-brain barrier in the brain stem during acute hypertension. We used a new method to …

The dynamics of an elevated cerebral venous pressure and its effect on cerebrospinal fluid
(CSF) pressure have been studied in considerable detail in the past [1, 4, 11, 14, 151 …

Acute arterial hypertension, induced by vasoactive substances or by compression of the
thoracic aorta, can increase the permeability of the blood-brain barrier (BBB) in experimental …

Acute hypertension was produced by perfusing isotonic saline solution for 3.5 sec into the
brain of rats via the common carotid artery, when the external carotid was ligated. The blood …

Cerebral blood flow (CBF) was measured in rabbits subject to acute hypertension produced
by angiotensin infusion. Hypertension led to cerebral hyperperfusion at the time of maximum …

The responses of cerebral (pial) arterioles to increased venous pressure were examined in
anesthetized cats equipped with cranial windows for the observation of the cerebral …

We studied disruption of the blood-brain barrier (BBB) by acute hypertension and a
hyperosmolar solution. The goals were to determine whether 1) disruption of the BBB occurs …

✓ The behavior of bridging veins at their entrance into the superior sagittal sinus during
elevated intracranial pressure (ICP) was investigated in rats using a cranial window and …

Acute arterial hypertension may damage the blood brain barrier function. In a previous study
[JoANssoN et al., 1970], it was found that an abrupt Aramine-induced blood pressure …
