The aim of the present work was to investigate the neuroprotective effects of early and late ischemic preconditioning (IPreC) in the acute phase of ischemic brain damage in rats. Single 5-min ischemic episodes of early IPreC were found not to produce significant neuroprotective effects as compared with controls, while three 5-min episodes of early IPreC led to significant increases in neurological deficit and increases in the level of neuron injury in hippocampal field CA1. Conversely, late IPreC, consisting of a single 5-min episode 24 h before modeling test ischemia, produced a significant neuroprotective effect, with decreased neurological deficit and retention of hippocampal field CA1 neuron viability.
