(A) Examples of T2 imaging and quantification of ventricular volume in male rats one day after injection of 50μl saline, deactivated Prx2 (Prx2(heat)) or Prx2 (25 μg) into the right lateral ventricle. Values are mean ± SD, n=10 in saline, n=6 in Prx2(heat) and n=13 in Prx2 group, #p<0.01 vs. saline group, ##p<0.01 vs. Prx2(heat) group; (B) Examples of H&E stained sections showing ventricle wall damage in male rats one day after intraventricular injection of saline, Prx2(heat) or Prx2 injection that are quantified in the bar graph. Values are mean ± SD, n=6, #p<0.01 vs. the other groups. Scale bar=50μm.
