Summary effects of blast overpressure on microglial activation. The effects of exposure of BV-2 microglial cells to blast overpressure Cox-2 protein levels at 3, 6 or 24 h is shown from 40 independent experiments. Cox-2 immunoblots for each experiment were scanned and normalized versus controls carried out for each separate experiment. Results (as fold-change) are presented as control versus pressure (A) or pulse duration (B). The symbol (X) indicates experiments where the protective parafilm cover on tissue culture dishes was broken during the procedure. These samples were included only when they did not show evidence of contamination.
