Graphs showing the medium value of immunopositivity observed at each time point for Caspase 9 and Caspase 3 respectively in skeletal muscle (A) and cardiac muscle (B): the skeletal muscle reactivity reveals an earlier pick of expression at 8 h, followed by a more gradual decrease of immunostaining, showing plateau stages at 8–12 h and 12–24 h respectively for Caspase 3 and Caspase 9; the reactivity in heart tissue shows an higher expression of Caspase 9 and 3 at 12 h, followed by an abrupt decrease and a plateau stage between 24 and 72 h.
