Figure 3.
TPEN treatment significantly decreased cytosolic labile zinc and ROS accumulation in ischemic brain tissue, and reduced the ischemic brain injury at 6 and 24h after reperfusion. TPEN was injected intraperitoneally 30min before MCAO. (A) Effect of TPEN on zinc accumulation as indicated by NG-stained cells. (B) Effect of TPEN on ROS formation as indicated by H2DCF-DA-stained cells. Bars=20μm. (C) Effect of TPEN on cerebral infarction volume, calculated by TTC-stained coronal sections. (D) Effect of TPEN on neurological assessment and motor function, assessed by neurological deficit scores and foot-fault-placing test. Data are means±SD (n=5 for A&B; n=8 for C&D). *P<0.05 vs vehicle-treated MCAO group.
