Electrophysiological assessments of mice after sciatic nerve crush injury.

Representative traces (A) of CMAP recorded following stimulating the distal (a) and proximal (b) portion of the regenerated nerve at the normal side and at the crushed side of mice receiving injection of saline, 2.5 mg/kg, 5.0 mg/kg, 10.0 mg/kg of ABPPk, and 16.0 mg/kg of ABPP at 21 days after surgery. (B) Bar graph illustrating the value of the CMAP amplitude recorded as outlined above. All data are presented as the mean ± SD (n = 10). *P < 0.05. vs. saline group; #P < 0.05. vs. normal side (one-way analysis of variance plus Scheffé post hoc test). ABPPk: Achyranthes bidentata polypeptides k fraction; CMAP: compound muscle action potential.
