Figure 4. A, Spinal cord section of the paraparetic rat (number 26) showing anterior horn gray matter with decreased number and size of motor neurons (arrows) and a blood vessel congested with lymphocytes (arrowhead; HE, 100X). B, Spinal cord section of the paraparetic rat (number 26) showing anterior funiculus white matter, with diffuse lymphocyte infiltration from congested blood vessels (arrowheads; HE, 400X). Scale: 200 µm for A and B. C, Lumbar spinal cord section of the paraplegic rat (number 33) showing the anterior horn with vacuolization and overall size reduction (HE, 100X). D, Astrocyte proliferation in the gray matter, with loss of neurons (HE, 400X). Scale: 200 µm for C and 50 µm for D.
