摘要：Summary. - The effects of electroacupuncture (EA) has been studied in a model of global cerebral
ischaemia performed in gerbils through the bilateral carotid artery occlusion (BCAO). Animals, under
isofluorane anaesthesia, underwent 5 min of BCAO and were killed after 7 days. The effects of EA were
evaluated both on functional (with electrophysiological recordings of synaptic potentials in hippocampal
slices) and morphological parameters (by counting the number of survived neurons in CA1 area of the
hippocampus). The results demonstrated that the treatment of animals with EA (5 min before, during and 20
min after BCAO and 30 min per day in the following 5 days) did not modify either the ischaemia-induced
reduction of synaptic potentials amplitude, either ischaemia-induced neuronal loss in the hippocampus. We
conclude that, at least in this animal model of cerebral ischaemia, EA does not exert a neuroprotective effect.
