The responses of cerebral precapillary vessels to changes in arterial blood pressure were
studied in anesthetized cats equipped with cranial windows for the direct observation of the …

Acute hypertension was induced in 19 anesthetized cats by the intravenous administration
of angiotensin. The caliber of pial arteries was measured by a television image-splitting …

SUMMARY We studied:(1) the effects of an abrupt, moderate increase in arterial pressure on
total and regional cerebral blood flow (CBF) and (2) whether sympathetic stimulation …

Acute severe hypertension induced by intravenous norepinephrine or angiotensin in
anesthetized cats equipped with a cranial window caused prolonged arteriolar vasodilation …

Previous studies have demonstrated a significant pressure gradient from carotid artery to
pial or middle cerebral arteries. This pressure gradient suggests that large cerebral arteries …

The responses of pial arterioles to changes in PaCOCO2 were studied in anesthetized cats
equipped with cranial windows for the observation of the pial microcirculation. The …

Chronic hypertension is associated with hypertrophy of cerebral blood vessels. Previous
studies of the mechanical properties of cerebral vessels in chronic hypertension have …

This study examined effects of local reductions in mean and pulse pressures on cerebral
arterioles in normotensive Wistar-Kyoto rats (WKY) and stroke-prone spontaneously …

Resistance of large arteries appears to be greater in the cerebral circulation than in other
vascular beds. Large arteries contribute importantly to total cerebral vascular resistance and …

The purpose of this study was to determine the microvascular characteristics that cause
cerebral cortical blood flow autoregulation to shift to a higher range of arterial pressures …
