Fig. 4. Neuroprotective effect of TTKFY on MPTP-induced locomotion impairments in zebrafish. (A) The digital track map. Red, green, and black lines represent fast, medium, and slow movement trajectories, respectively. n?=?8 per group. (B) The total distance moved in control, MPTP, and MPTP?+?TTKFY groups. n?=?8 per group. (C) Average movement speed of larvae for different treatment groups. n?=?8 per group. Average speed in every 60?s was calculated. TTKFY ? Tongtian oral liquid. **P?0.01, compared with the MPTP treatment group, #P?0.05. (D) Pearson?s Correlation Coefficient analysis reveals the positive correlation between locomotor dysfunction and the percentage of decrease of DAnergic neurons. Correlation is significant at the level of P?0.001.
