Altered Regional Cerebral Blood Flow in Chronic Whiplash Associated Disorders
There is increasing evidence of central hyperexcitability in chronic whiplash-associated disorders (cWAD). However, little is known about how an apparently simple cervical spine injury can induce changes in cerebral processes. The present study was designed (1) to validate previous results showing alterations of regional cerebral blood flow (rCBF) in cWAD, (2) to test if central hyperexcitabili...
متن کاملRegional Cortical Blood Flow
We conducted regional cortical blood flow studies using the xenon-133 clearance technique on 12 volunteers during the administration of 25% and 50% N2O and during baseline conditions (breathing room air or 100% O2). Global cortical blood flow was very highly significantly increased above baseline measures in all subjects by 50% N2O (mean increase 37% above 100% O2 condition). A smaller but stil...
متن کاملRegional Myocardial Blood Flow
Do oxygen-derived free radicals, generated at the time of reperfusion, lethally injure viable, previously ischemic myocardium, damage vascular endothelium, and impair recovery of postischemic contractile function? To address these issues, 23 anesthetized open-chest dogs underwent 2 hours of left anterior descending coronary artery occlusion followed by 4 hours of reperfusion. Immediately prior ...
متن کاملRegional Myocardial Blood Flow
nary artery disease has provided an intense stimulus for expansion of our present knowledge of the coronary circulation. In the experimental animal laboratory, the electromagnetic flowmeter has proved to be an excellent tool by which one can study dynamic aspects of the coronary circulation. A flowmeter is clearly unsuitable for human investigation; therefore, the search for a simple method of ...
متن کاملRegional Pulmonary Blood Flow
unteers were studied, nine sitting and seven supine. During hypoxia there was a slight but significant increase in relative perfusion of the upper portions of the lungs in both the sitting and supine subjects. During recovery from hypoxia, blood flow distribution differed significantly from the control. The erect subjects showed increased relative perfusion of the lung bases and the supine subj...
