This study examined the time course of the blood-brain barrier (BBB) opening and correlated this with brain edema formation after a lateral controlled cortical impact (CCI) brain injury in rats. Quantitative measurement of Evans blue (EB) extravasation using fluorescence was employed at 2, 4, 6 h and 1, 2, 3, 4 and 7 days after injury. Brain edema was(More)
Somatosensory evoked potentials (SEP's) reflect the integrity of the central neuronal pathway, and as such may be used to assess function that remains during a variety of cerebral insults. To evaluate the natural history and utility of SEP's during experimental cerebral ischemia and infarction, SEP's were measured in 17 adult cats at 24 hours and 1 hour(More)
We have previously reported that ischemia reperfusion injury results from free radical generation following transient global ischemia, and that this radical induced damage is evident in the synaptosomal membrane of the gerbil. [Hall et al, (1995) Neuroscience 64: 81-89]. In the present study we have extended these observations to transient focal ischemia in(More)
PURPOSE To investigate macular structural characteristics in children with congenital or developmental cataracts. METHODS Children 5-16 years of age with a history of surgery for congenital or acquired cataract were enrolled. Eligible patients had visual acuity of 20/400 or better and ≥37 weeks gestational age at birth. Patients were divided into two(More)
