Regional blood flow during hyperoxic haemodilution
Clinical Physiology and Functional Imaging, 2005SummaryBackground: Ventilation with pure oxygen (hyperoxic ventilation, HV) increases arterial oxygen content (CaO2). However HV induces arteriolar constriction and thus potentially affects O2 supply. We therefore investigated the effects of HV on regional blood flow (RBF) and O2 supply of different vital organs during moderate normovolaemic anaemia ...

REGIONAL CEREBRAL BLOOD FLOW IN NEUROPSYCHOLOGY
Neuropsychologia, 1986Measurements of regional cerebral blood flow (rCBF) provide information about the metabolic and functional level of the cortex. Different techniques for measurement of rCBF are described and their potentials and limitations are outlined. Typical results from measurements in normals during performance of mental tasks are shown and as well as clinical ...

Regional Coronary Blood Flow in Ponies
American Journal of Veterinary Research, 1976SUMMARY Regional coronary blood flow was measured by injecting radioactive microspheres (15 μm ± 5 in diameter) into the left atrium of anesthetized ponies with surgically prepared open thorax before and during occlusion of the coronary arteries. The normal blood flow to the myocardium of the interventricular septum and the left ventricular wall were ...

Regional Cerebral Blood Flow in Depression
Psychiatry and Clinical Neurosciences, 1990Abstract: Regional cerebral blood flow (rCBF) was measured in patients with endogenous depression by the single photon emission computed tomography (SPECT) using N‐isopropyl‐p‐[123I] iodoamphetamine (IMP). The subjects were 32 patients with endogenous depression and 20 normal controls.

Regional blood flow in hemorrhagic shock
The American Journal of Surgery, 1961T HIS STUDY represents an attempt to heIp cIarify the relationships between various degrees of acute hemorrhage and regiona blood fIow. The reaI measure of the degree of shock in a given situation is the quantitative regiona flow of oxygenated bIood in reIation to tissue metaboIic needs.

Regional Cerebral Blood Flow in Aphasia
Archives of Neurology, 1978Regional cerebral blood flow (rCBF) was studied in 13 aphasic patients with left hemisphere lesions, using the intracarotid xenon 133 injection method and a 254-detector gamma camera system. The rCBF was measured during rest and during various function tests, including a simple speech test.

Regional Cerebral Blood Flow in Schizophrenia
Archives of General Psychiatry, 1982Regional cerebral blood flow (rCBF) was measured via xenon133 inhalation technique in 23 patients with schizophrenia and 18 age- and sex-matched controls. The mean blood flow to both hemispheres was found to be lower for the patients. The patients and their controls did not differ on interhemispheric differences in blood flow. There were no differences

Personality and Regional Cerebral Blood Flow
British Journal of Psychiatry, 1984SummaryThe extraversion–introversion dimension of personality is believed to have an inverse relationship with cortical arousal. Brain capillary perfusion is a well established index of brain function and arousal. Regional cerebral blood flow was measured in 51 right-handed females whose personality structure was examined with the Eysenck Personality ...

Regional blood flow during periodic acceleration
Critical Care Medicine, 2001To determine whether a motion platform that imparts noninvasive periodic acceleration (pGz) forces to the body causes systemic vasodilation and changes local organ blood flow.Prospective paired blocked design.Medical center research laboratory.Juvenile Yorkshire pigs.Juvenile pigs (12 kg) were anesthetized, paralyzed, and placed on a motion platform ...

Regional Renal Blood Flow in Ewes
American Journal of Veterinary Research, 1981SUMMARY Regional blood flow to the kidneys was measured in 6 ewes by injecting carbonized microspheres (15 μm ± 5) labeled with 85Sr into the left ventricle. There was no significant (P > 0.25) difference in the mean arterial pressure before and after injection of the microspheres.
