Figure 10. Treatment with 10 µM KB-R7943 (KBR), but not 10 µM MDL28170 (MDL) reduced the level of troponin I in the coronary effluent from the Ca²⁺ paradoxic hearts.

Each bar represents the mean±SEM, n = 6. ^## P<0.01 vs. the control, ^† P<0.01 vs. the 3-min Ca²⁺ depletion group (CaD3), **P<0.01 vs. the corresponding group without the drug. MDL+C, MDL28170 control; KBR+C, KB-R7943 control; and CaD5, 5-min Ca²⁺ depletion group.
