Variations in middle cerebral artery blood flow investigated with noninvasive transcranial blood velocity measurements.
Observations on blood velocity in the middle cerebral artery using transcranial Doppler ultrasound and on the ipsilateral internal carotid artery flow volume were obtained during periods of transient, rapid blood flow variations in 7 patients. Five patients were investigated after carotid endarterectomy. A further 2 patients having staged carotid endarterectomy and open heart surgery were inves...
متن کاملThe Behavior of Renal Blood Flow after Partial Constriction of the Renal Artery
1. Studies have been made of the behavior of renal blood flow after partial constriction of the renal artery in twenty-four dogs. 2. When reduction in renal blood flow is produced by partial constriction of the renal artery, a readjustment of flow in the direction of normal occurs within a few minutes, subsequent constriction being again followed by a return of flow toward normal until the arte...

15 صفحه اولIncreasing Renal Blood Flow
Background and objectives: Many clinicians believe that low-dose dopamine (LDD) [2 g/kg/min] increases renal blood flow (RBF) and medium-dose norepinephrine (MD-NE) [0.4 g/kg/min] decreases RBF. They also believe that MD-NE might induce mesenteric and/or coronary ischemia. In fact, the effects of these drugs on renal and vital organ blood flow are poorly understood. The aim of this study was to...
متن کاملNitric oxide dependence of renal blood flow in patients with renal artery stenosis.
In ischemia, nitric oxide (NO) production is increased, possibly to preserve flow. The role of NO was investigated in hypertensive patients with or without renal artery stenosis (RAS). Fifty-five hypertensive patients scheduled to undergo diagnostic renal angiography underwent mean renal blood flow (MRBF) measurements before and after an intrarenal injection of the NO synthase blocker N(g)-mono...
