Abstract：
:Brain swelling is a serious complication associated with focal ischemia in stroke and severe head injury. Experimentally, reperfusion following focal cerebral ischemia exacerbates the level of brain swelling. In this study, the permeability of the blood-brain barrier has been investigated as a possible cause of reperfusion-related acute brain swelling. Blood-brain barrier disruption was investigated using Evans Blue dye and [14C]aminoisobutyric acid autoradiography in a rodent model of reversible middle cerebral artery (MCA) occlusion. Acute brain swelling and cerebral blood flow (CBF) during ischemia and reperfusion were analyzed from double-label CBF autoradiograms after application of the potent vasoconstrictor peptide endothelin-1 to the MCA. Ischemia was apparent within ipsilateral MCA territory, 5 min after endothelin-1 application to the exposed artery. Reperfusion, examined at 30 min and 1, 2, and 4 h, was gradual but incomplete within this time frame in the core of middle cerebral artery territory and associated with significant brain swelling. Ipsilateral hemispheric swelling increased over time to a maximum (>5%) at 1-2 h after endothelin-1 but was not associated with a significant increase in the ipsilateral transfer constant for [14C]aminoisobutyric acid over this time frame. These results indicate that endothelin-1 induced focal cerebral ischemia is associated with an acute but reversible hemispheric swelling during the early phase of reperfusion which is not associated with a disruption of the blood-brain barrier.
