Rats were treated with PLA-E2 (5 μg), and spinal cords were collected at seven days post injury. Tissues were homogenized and analyzed by western blotting for Iba-1 (A) and GFAP (B) as described in the methods. Densitometric analysis of protein band intensity (lower panels) suggests that Iba-1 and GFAP expression levels were significantly inhibited by PLA-E2 treatment (N = 3–4 per group)
