Survival of Dopaminergic Amacrine Cells after Near-Infrared Light Treatment in MPTP-Treated Mice

Figure 2

Graphs showing (a) the areas and (b) the number of TH⁺ amacrine cells in the retinae in the four experimental groups in the different cases (different shaded columns). Columns show the mean ± standard error of the total number of cells in each case. ^†Represents 𝑃<0.001, ^∧represents 𝑃<0.01 and *represents 𝑃<0.05 significant difference in cell number; these symbols on the columns of the MPTP group represent differences from the Saline group of each case, while symbols on the MPTP-NIr group represent differences from the MPTP group of each case. There were clear increases in TH⁺ cell number in the MPTP-NIr group compared to the MPTP group in all cases, particularly the Ac-PT, Ch-Sim, and Ch-PT.
