Metabolic alterations in rabbit cerebral arteries caused by subarachnoid hemorrhage.
The effect of subarachnoid hemorrhage on metabolic rates in rabbit cerebral arteries was investigated by measuring adenosine triphosphate (ATP) content and L-lactate release. The mean +/- SEM ATP content was 0.38 +/- 0.02 mumol/g wet wt in control rabbit basilar arteries (n = 6). The ATP content decreased significantly to 0.17 +/- 0.02 mumol/g wet wt 2 days after experimental subarachnoid hemor...
متن کاملBiaxial and failure properties of passive rat middle cerebral arteries.
Rodents are commonly used as test subjects in research on traumatic brain injury and stroke. However, study of rat cerebral vessel properties has largely been limited to pressure-diameter response within the physiological loading range. A more complete, multiaxial description is needed to guide experiments on rats and rat vessels and to appropriately translate findings to humans. Accordingly, w...
متن کاملMiddle cerebral artery variations: duplicated and accessory arteries.
PURPOSE Our goal was to analyze the anatomic similarity between the duplicated middle cerebral artery (MCA) and the accessory MCA and their relationship to the early branches of the MCA. METHODS We reviewed stereoscopic angiograms of duplicated MCAs in four patients and accessory MCAs in four patients with reference to the origin, size, and cortical supply of these anomalous vessels, along wi...
متن کاملGrading of Intracerebral Hemorrhage in Ruptured Middle Cerebral Artery Aneurysms
OBJECTIVE To propose grading of intracerebral hemorrhage (ICH) in ruptured middle cerebral artery (MCA) aneurysms, which helps to predict the prognosis more accurately. METHODS From August 2005 to December 2010, 27 cases of emergent hematoma evacuation and aneurysm clipping for MCA aneurysms were done in the author's clinic. Three variables were considered in grading the ICH, which were 1) he...
متن کاملLoss of CO2-induced distensibility in cerebral arteries with chronic hypertension or vasospasm after subarachnoid hemorrhage.
We developed a rat cerebral angiography system using monochromatic synchrotron radiation X-rays at SPring-8, a third generation synchrotron radiation facility. Using new technique, we assessed the distensibility of major trunk arteries after subarachnoid hemorrhage (SAH) in normotensive and hypertensive rats. Twenty-five adult Wistar Kyoto rats (WKY) and fourteen stroke-prone spontaneously hype...
