15 صفحه اولBlood flow after retinal ischemia in cats.
PURPOSE To determine the changes in blood flow in the cat retina after 1 hour of ischemia. METHODS Blood flow in the retina and choroid of adult cats anesthetized with chloralose, acepromazine, and halothane was measured using sequential injections of radioactively labeled microspheres. Ischemia was induced by elevation of intraocular pressure above systolic arterial pressure. Measurements we...
متن کاملRegional cerebral blood flow changes in motor cortical areas after transient anesthesia of the forearm.
To study the effect of deafferentation on cortical areas activated by movement of the proximal muscles, we measured regional cerebral blood flow with positron emission tomography and 15O-labeled water. Flexion-extension movements of the right elbow before deafferentation were associated with an increase of regional cerebral blood flow in the primary sensorimotor area bilaterally, posterior supp...
متن کاملA decrease in spatially resolved near-infrared spectroscopy-determined frontal lobe tissue oxygenation by phenylephrine reflects reduced skin blood flow.
BACKGROUND Spatially resolved near-infrared spectroscopy-determined frontal lobe tissue oxygenation (ScO2) is reduced with administration of phenylephrine, while cerebral blood flow may remain unaffected. We hypothesized that extracranial vasoconstriction explains the effect of phenylephrine on ScO2. METHODS We measured ScO2 and internal and external carotid as well as vertebral artery blood ...
متن کاملForearm blood flow during and after isometric hand-grip contractions.
1. A method is described for the measurement of forearm blood flow during sustained voluntary isometric hand-grip contractions that can be maintained constant by the subject’s monitoring of the strength of his contractions. 2. In most subjects it was found that contractions of 5% of their maximal voluntary force could be maintained without fatigue, and without any post-exercise increase in bloo...
