Effects of changing the oxidative status on enzyme release from isolated liver mitochondria from control and PH rats. Results are expressed as mean ± SE of four individual observations per experimental point and correspond to the percentage of the released enzyme in respect to the total mitochondrial activity for each enzyme. Bas: basal, Subs: substrates, H₂O₂: hydrogen peroxide, and BHT: butylated hydroxytoluene. Statistical significance: ^∗ p < 0.01 against the group of sham-operated controls (incubated with substrates); ^∗∗ p < 0.01 versus PH rats group (incubated with substrates).
