Cerebral circulation in experimentally-induced cerebrovascular accidents

Experimental Neurology, 1969
Abstract The cerebral blood-flow changes and their relation to the systemic blood pressure were studied on two experimental models of cerebrovascular accidents (intracerebral hematoma and cerebral softening). The cerebral blood flow measured with thermistores was found to be significantly increased in both hemispheres for either experimental model ...

Circulating endothelial microparticles as a marker of cerebrovascular disease

Annals of Neurology, 2009
AbstractObjectiveCirculating endothelial microparticles (EMPs) have been reported to reflect vascular damage. Detailed profiling of these blood endothelial markers may adumbrate the pathogenesis of stroke or enable determination of the risk for stroke. We investigated EMP profiles in patients at risk for cerebrovascular disease.MethodsWe prospectively ...

Hydergine effect on cerebral circulation in cerebrovascular disease

Journal of the Neurological Sciences, 1971
Abstract Cerebral blood flow (CBF) was measured in 10 patients with cerebrovascular disease and in 2 normal individuals using the 133Xenon injection technique. After control measurements were performed, 0.6–1.2 mg of Hydergine was given intramuscularly.

Circulating norepinephrine and cerebrovascular control in conscious humans

Clinical Physiology and Functional Imaging, 2003
SummaryBackground:  Cerebral vasoconstriction without concurrent changes in systemic arterial blood pressure has been observed in both normal individuals and those with idiopathic orthostatic intolerance following several minutes of postural stress when circulating catecholamines are elevated.

Studies on Improved Model for Cerebrovascular Blood Circulation

2001
For the elastic cavity model adopted in the existing cerebrovascular hemodynamics analyzers was too simple, we developed the improved model for cerebrovascular blood circulation to describe more exactly the physiologic nature of both sides cerebrovascular blood circulation and the relation between them (Willis Circle).

[Cerebrovascular circulation in patients with oligomenorrhea].

Akusherstvo i ginekologiia, 1993
Brain hemodynamics was studied in 76 patients with oligomenorrhea aged 18 to 35 from the data of rheoencephalography. Disorders of the regional tone of brain vessels were different and related to the time of the menstrual cycle disorder; this may be explained by the degree of changes in various neuromediator mechanisms of brain circulation and ...

IDENTIFYING CIRCULATING MEDIATORS OF CEREBROVASCULAR DISEASE

2021
Many current drugs for stroke act by targeting circulating molecules, yet these have not been exhaustively evaluated for therapeutic potential. A central challenge is that while many molecules correlate with stroke risk, only a subset cause stroke.

[Effect of ornid on the regulation of cerebrovascular circulation].

Biulleten' eksperimental'noi biologii i meditsiny, 1979
An investigation of ornid, using radioisotopic, electromagnetic and resistographic methods, has shown the drug to diminish cerebral circulation and to abolish completely the constriction of the brain vessels induced by stimulation of the sympathetic and somatic nerves.
