Expression of AchE in the NMJ at different times after contusion. (a) AchE GENMED frozen section staining at the NMJ (200×) at different time points after contusion. (b) Comparison of AchE expression levels at different times after contusion. Contusion versus normal, ^##P < 0.01; EA versus contusion, ^▲▲P < 0.01 (n = 5).
