Figure 7. Dose-dependent inhibition of complex I of the respiratory chain by bupivacaine and ropivacaine. Each point represents the average value from three measures. Curves are fitted as described in Materials and Methods section. The half-inhibitory concentrations are equal to 0.38 +/- 0.04 mM and 0.36 +/- 0.03 mM for bupivacaine and ropivacaine, respectively.
