Multiple parameters improved in D/L-BHB-treated samples 24 h after injury. (A) The velocity of the cells migrating in the BHB-treated sample was significantly higher (p = 0.00041), compared to the control. The graph shows individual values as well as the mean. (B) The estimated plot of the distance traveled by cells migrating in the BHB-treated samples were higher, compared to the control (p = 0.0041). (C) Significantly more synapsin-I was found in the BHB-treated samples, compared to the control (p = 0.006). (D) Significantly more beta-III-tubulin was found in the BHB-treated samples, compared to the control (p = 0.0435). * p < 0.05, ** p < 0.01.
