Figure 2: Inhibitory effects of increasing concentrations of chromium versus percent of decrease of the electrical properties of potential difference and short-circuit current on isolated toad skin. (a) Outer surface 33, 100, and 200 μM of chromium, (b) inner surface 33, 100, and 200 μM of chromium (*P < 0.05; **P < 0.01; ***P < 0.001) |
