The mRNA level of GAP-43 increased after the TQSS and EPSI treatment. a The representative graphic of GAP-43 mRNA expression level analyzed by agarose gel electrophoresis. The lanes were loaded with samples from control group without drugs, 250, 500 and 1000 mg/L TQSS. b The GAP-43 mRNA expression for three independent experiments were analyzed and plotted. The gel image (c) and column chart (d) for EPSI group are shown at the bottom and the EPSI concentrations are 100, 250 and 500 mg/L, respectively. Data are expressed as mean ± SD, n = 3, *p < 0.05, **p < 0.01 versus the group without drugs
