Figure 2.

The change of intracellular superoxide level after withdrawal of the inhibitors of electron transport chain. HT22 cells were treated with rotenone (0.5 µM), malonate (5 mM), antimycin A (20 µM) and stigmatellin (20 µM) for 30 min, then washed and recovered in normal medium for up to 8 h. Average values and SD are shown, N=3.
