The Clinical Study on Bell's Palsy Patients with TCD Measurement

Journal of Pharmacopuncture, 2003
Objective : This study was carried to make out the connection between cerebral artery blood flow velocity and ischemic theory that presumed the cause of Bell's palsy. Method : We measured cerebral artery blood flow velocity each external carotid artery,

Image Guidance for Transcranial Doppler Ultrasonography

, 2011
BACKGROUND: Transcranial Doppler (TCD) ultrasonography is an important tool for noninvasive detection and monitoring of vasospasm and other pathological conditions of the intracranial vessels.

Mechanisms regulating cerebral perfusion during running exercise: Influence of foot strike‐induced pulsatility oscillations, CO2 reactivity and BP

The Journal of Physiology, EarlyView.
Abstract figure legend Young, healthy males and females completed an incremental running test, demonstrating a progressive increase in middle cerebral artery blood velocity (MCAv) up to maximal exercise despite reductions in end‐tidal CO2. To investigate the underlying mechanism, foot‐strike timing was synchronized to the diastolic phase of the cardiac

Prognosis of acute hemiplegia estimated by transcranial Doppler ultrasonography.

, 1988
Blood velocity in the middle cerebral artery was measured by transcranial Doppler ultrasonography in 15 patients suffering complete hemiplegia of less than 12 hours' duration, presumed due to cerebral ischemia. Among seven patients in whom blood velocity

Transcranial Doppler ultrasonography of the basilar artery in patients with retrograde vertebral artery flow [PDF]

, 2008
ObjectiveReversal of flow in the extracranial vertebral artery secondary to a proximal subclavian/innominate artery stenosis or occlusion is a frequent finding during carotid duplex ultrasonography. The characteristics of basilar artery flow are not well

Type A botulinum toxin (disport) in treatment of chronic forms of primary headache

Бюллетень сибирской медицины, 2008
The aim of this investigation is to study the effect of BTA on the cerebral blood flow in patients with chronic daily headache. The analysis of Doppler ultrasonography and transcranial Dopplergraphy findings has shown the following: after the treatment ...

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...
