FIGURE 1.

Cardiomyocyte contractile function and cell injury following doxorubicin and luteolin (at various concentrations) exposure for 24 h. (A) Resting cell length; (B) Peak shortening (PS); (C) Maximal velocity of shortening (–dL/dt); (D) Maximal velocity of relengthening (+dL/dt); (E) Time-to -peak shortening (TPS); (F) Time-to-90% relengthening (TR₉₀); (G) LDH; and (H) CK. Mean ± SEM, n = 30 cells each group from three independent experiment. * p < 0.05 vs. CON group, # p < 0.05 vs. DOX group.
