Expression of Agrin in the NMJ at different times after contusion. (a) DAB staining of Agrin in the NMJ on days 7, 14, and 28 after contusion (400×). (b) Comparison of the expression levels of Agrin on days 7, 14, and 28. Contusion versus normal, ^##P < 0.01; EA versus contusion, ^▲▲P < 0.01, ^▲P < 0.05 (n = 5).
