  1. Results were represented as mean (SD), n = 8 for tMCAO Ar group and n = 7 for tMCAO N2 group. Time 1 = baseline, 5 min after tail artery catheter insertion, Time 2 = after tMCAO induction, Time 3 = after onset of reperfusion, Time 4 = after the beginning of gas application (50% vol N2/50% vol O2 for tMCAO N2 group, 50% vol Argon/50% vol O2 for tMCAO Ar group)
