FIG. 1.

The effect of aminochrome on cell death in RCSN-3 cells. The cell death of RCSN-3 cells incubated during 24 or 48 h was measured as described under “Materials and Methods” section. A significant cell death induced 50μM aminochrome (AM) in the absence and presence of 100μM DIC (AM + DIC) after 48-h incubation. No significant cell death was observed in cells treated with 100μM DIC or incubated with cell culture medium. The values are the mean ± SD (n = 3), and the statistical significance was assessed using ANOVA for multiple comparisons and Student’s t-test (**p < 0.01).
