Figure 5From: The problem of axonal injury in the brains of veterans with histories of blast exposure Stereological areal fraction analysis of APP-positive axonal injury signal in blast (n = 4) and methadone (n = 4) cases. Coronal sections through the frontal lobe were stained by APP N-terminal antibody (see Materials and Methods). Axon injury signal was counted (a) and analyzed by two-tail student’s t-test (b). Difference between blast and methadone cases was significant at P value 0.0195.Back to article page
