The most common cause of decerebrate posture is brain damage at the level of the brain stem. However, decerebration could occur without any brain stem damage by occlusion of both carotid arteries (1, 2). A 60-year-old man was admitted to the hospital because of loss of consciousness while working, immediately followed by decerebrate extensor posture. An electrocardiogram showed atrial fibrillat...

BACKGROUND AND PURPOSE Diabetes mellitus may impair endothelium-dependent responses in cerebral arterioles. The basilar artery dilates in response to increases in blood flow. The goal of this study was to examine effects of diabetes mellitus on "flow-mediated" and endothelium-dependent dilatation of the basilar artery. METHODS Diabetes was induced in rats with 50 mg/kg streptozotocin. Six mon...

We report a case of middle-aged woman incidentally diagnosed with Takayasu arteritis during the ultrasonography of a thyroid gland nodule. Prominent collaterals of the thyroidal arteries and a thin common carotid artery with mural thickening and deficient intraluminal flow signals were initially depicted on the ultrasonography with color Doppler. Subsequent magnetic resonance angiography and co...

IRIUCHIJIMA, JURO, AND HIROYUKI KOIKE. Carotid flow, intrasinusal pressure, and collateral flow during carotid occlusion. Am. J. Physiol. 218(3) : 876-879. 1970.-Bilateral common carotid flow and systemic as well as intrasinusal pressure were observed in anesthetized dogs. Unilateral common carotid occlusion induced about a 30y0 increase in contralateral common carotid flow, mainly due to colla...

Moyamoya disease is a stenoocclusive disease involving the intracranial carotid and proximal middle cerebral arteries. There are rarely any additional extracranial stenoses occurring concurrently with moyamoya. The pathophysiology of moyamoya remains obscure, but hematologic disorders, notably sickle-cell anemia, have been associated in some cases. We describe the novel case of polycythemia ver...

The no-reflow phenomenon has been produced in the cerebral hemispheres of the gerbil by 30 minutes of bilateral carotid artery occlusion. The no-reflow phenomenon was found to develop in relation to the fall in blood pressure which occurred on release of bilateral carotid clips. Metaraminol tartrate intravenously prevented the fall of blood pressure and significantly reduced the occurrence of t...

Objective(s):The major objective of the present study was to investigate the potential neuroprotective effect of berberine chloride on vascular dementia. Berberine, as an ancient medicine in China and India, is the main active component derived from the Berberis sp. Several studies have revealed the beneficial effects of berberine in various neurodegenerative disorders. Materials and Methods: T...
