Cerebral Blood Vessels and Stroke:

Blood vessels, migraine, and stroke.

See related article, pages 3145–3151. The relation between migraine and stroke has been well recognized and has been the focus of several publications.1–3 Despite many hypotheses linking the 2 disorders, the precise mechanisms are unknown, and not surprisingly very complex. In this issue of Stroke, Pezzini and colleagues4 add to this complexity by suggesting that migraine with aura may “mediate...

Of cerebral blood flow, stroke and SPECT.

Thermal reactions of blood vessels in vascular stroke and heatstroke.

Research on the pathophysiology and treatment of brain damage with special focus on thermal vascular responses is the subject of this minireview. Interruption of cerebral blood supply by vascular obstruction, temporary cardiac arrest or hyperthermia causes a sudden attack of vascular stroke or heatstroke with serious consequences. It may not induce immediate cell death, but can precipitate a co...

A Comparison of Cerebral and Extracerebral Blood Vessels

The number of adrenergic nerves was quantified, on both cerebral and femoral blood vessels. No difference was found between the two vascular beds. The data failed to establish a "richer" innervation of cerebral vessels. This is in agreement with my previous, extensive, subjective and unpublished impression. Consequently, the suggestion of others, which ascribes certain features of cerebrovascul...

Role of Local Nerves and Prostaglandins in Regulation of Basal Blood Flow and Hypercapnic Vasodilatation of Cerebral Blood Vessels in the Rabbit

The mechanisms underlying cerebral vasodilatation during hypercapnia are not fully understood. To examine the role of nerves and prostaglandins in the regulation of basal blood flow and in hypercapnia-induced vasodilatation in the cerebral blood vessels of rabbit.Cerebral blood flow was measured by laser Doppler flow-meter in 18 NZW rabbits anesthetized with sodium pentobarbital.  Tetrodetoxin ...
