Au decreased the neural apoptosis and neuronal loss caused by TBI. a, b Representative WB bands (a) and quantification of relative protein expression (b) for Bcl2, Bax, and CC3. c–f Representative photomicrographs and quantification of TUNEL staining (c, e Scale bars = 20 μm) and Nissl staining (d, f Scale bars = 50 μm) in cortex of the traumatized side. The red arrow indicated damaged neurons. g Diagram of mouse brain section showing the location of lesion cavity (red area) and photograph region (red squares). Bars represent the mean ± SD. *P < 0.05 versus indicated groups (n = 6 for each group)
