Mechanism(s) of Toxic Action of Zn²⁺ and Selenite: A Study on AS-30D Hepatoma Cells and Isolated Mitochondria

Figure 1

Time- and dose-dependent action of Zn²⁺ and selenite on AS-30D cell viability assayed by the trypan blue exclusion test. Time of incubation used was 3, 24, and 48 h. The results are expressed in % to corresponding control and presented as mean values of four independent experiments ±SE. *P < 0.05.
