Intravenously injected metaraminol induced a larger blood pressure increase in spontaneously hypertensive rats (SHR) than in normotensive controls (NR) when the pressure was raised from the same starting level. Cerebral blood flow (CBF) response in NR was either perfect autoregulation, partial autoregulation or "break-through." When present, the autoregulatory response was very rapid, i.e. the ...

See related article, pages 2540-2545. Animal models have shown that cholesterol-lowering therapy with 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (commonly called statins) may augment absolute cerebral blood flow (CBF) by enhancing nitric oxide synthase (eNOS).1 Statins upregulate type III endothelial eNOS in thrombocytes, decrease platelet activation, and protect from cerebral i...
normal 0 false false false en-us x-none ar-sa background: neuropsychiatric abnormalities are among the most common manifestations of systemic lupus erythematosus (sle). they have been proposed to be associated with impaired cerebral blood flow (cbf). cerebral vasomotor reactivity (vmr) is a hemodynamic parameter effective in the autoregulation of cbf. the aim of the present study is to determin...
BACKGROUND The circle of Willis provides collateral pathways to perfuse the affected vascular territories in patients with severe stenoocclusive disease of major arteries. The collateral perfusion may become insufficient in certain physiological circumstances due to failed vasodilatory reserve and intracranial steal phenomenon, so-called 'Reversed-Robinhood syndrome'. We evaluated cerebral hemo...
