Effect of the administration of AST and injection of ISO on H₂O₂ production in rat heart mitochondria. (a) H₂O₂ production in the presence of EGTA; (b) H₂O₂ production in the presence of threshold [Ca²⁺]; (c) H₂O₂ production in the presence of Antimycin A; (d) H₂O₂ production in the presence of menadion. The data are presented as means ± SDs of four independent experiments. * p < 0.05 indicates a significant difference in the protein level relative to the control (group 1). The statistical significance of the differences between the pairs of the mean values was evaluated using the ANOVA type 2 (Student–Newman–Keuls) test.
