| Research Abstract |
The present study suggests that neutrophil elastase possibly, but may not exclusively, derived from activated leukocytes contributes to the development of selective neuronal death in hippocampal CA1 after 8 min-forebrain ischemia in rats and that a specific neutrophil elastase inhibitor, ONO-5046, ameliorates neuronal damage via inhibition of neutrophil elastase distribution in the extracellular matrix after ischemia. Further study may be needed to determine the therapeutic time window for ONO-5046 and the effects of higher or repeated doses as well as the detailed mechanisms for interaction between neutrophil elastase and activation of caspase.
