摘要
K+ currents of activated glial cells surrounding ischemic infarcts are investigated using acutely dissociated cells from the periinfarct area after permanent middle cerebral artery occlusion in rats. Inwardly rectifying K+ currents (K-1R) were markedly reduced in cells neighboring infarcts with maximal alteration at day 3 after infarct followed by a partial recovery. This reduction of glial K-1R currents may contribute to the functional disturbances in the periinfarct area. (C) 2000 Elsevier Science B.V. All rights reserved.
