Fig. 6. Experiment 2: Neurologic outcome in each animal of four groups 48 h after reperfusion (* P < 0.01 vs. O2; # P < 0.01 vs. DMTU+Iso). ▴, ˆ, •, and ▵ represent animals in the O2, Iso, DMTU+Iso, and DMTU+O2groups, respectively. O2and Iso: animals received saline intraperitoneally 1 h before each session of oxygen pretreatment and isoflurane pretreatment, respectively; DMTU+Iso and DMTU+O2: animals received the same volume of dimethylthiourea (DMTU, a free radical scavenger) intraperitoneally 1 h before each session of oxygen and isoflurane pretreatment, respectively.
