Representative micrographs depicting I/R-induced activation of astrocytes (GFAP) and microglial cells (Isolectin-B4) in the hippocampal CA1 subfield of mice subjected to sham (A, I), I/R (B, J), ethanol and NS 1619 administration 24 hrs prior to I/R (EtOH-PC+I/R and NS-PC+I/R) (C, K and E, M), paxilline treatment coincident with ethanol and NS1619 administration, 24 hrs prior to I/R (PX+EtOH-PC+I/R and PX+NS-PC+I/R) (D, L and F, N), paxilline alone 24 hrs prior to I/R (PX+I/R) ( G, O), and both EtOH-PC and NS-PC 24 hrs prior to I/R(EtOH-PC+NS-PC+I/R) (H, P).
