Evolution of blood-brain-barrier permeability after acute ischemic stroke
The dynamics of BBB permeability after AIS in humans are not well understood. In the present study we measured the evolution of BBB permeability after AIS in humans using MRI. Patients presenting to our institution with a diagnosis of AIS underwent a single dynamic contrast-enhanced MRI (DCE-MRI) sequence to measure BBB permeability during their initial workup. Forty-two patients were included ...
متن کاملTemporal changes in blood–brain barrier permeability and cerebral perfusion in lacunar/subcortical ischemic stroke
BACKGROUND Cerebral microvascular abnormality is frequently associated with lacunar and subcortical ischemic lesions. We performed acute and follow-up CT perfusion scans over the first 3 months after ischemic stroke to investigate disturbances of the blood-brain barrier (BBB) and cerebral perfusion in patients with lacunar/subcortical lesions compared to those with cortical lesions alone. MET...
متن کاملP 19: The Effects of Aloe Vera Extract on Brain Edema and Blood-Brain Barrier Permeability after Traumatic Brain Injury
Introduction: Recent studies have reported that the Aloe vera (Aloe barbadensis miller) plant has anti-inflammatory and antioxidant effects. This study evaluated the neuroprotective effects of different doses of Aloe vera extract after traumatic brain injury (TBI) in male rats. Materials and Methods: In this study, 70 male rats were divided into 2 groups; each group consists of 5 of sub-g...

متن کاملEarly changes in blood brain barrier permeability to small molecules after transient cerebral ischemia.
Brain unidirectional extraction and flux of leucine were measured simultaneously with cerebral blood flow (CBF) at various times after transient global cerebral ischemia in the rat. The results permit an evaluation of blood-brain barrier permeability in the postischemic period independent of alterations in CBF at the time of measurement. Leucine extraction was higher (p less than 0.001) than th...
