Figure 1. The effects of treatment with 10 µM KB-R7943 or 10 µM MDL28170 on the survival of heart tissue after the 3-min Ca²⁺ depletion treatment.

A. Representative TTC staining for hearts subjected to the 3-min Ca²⁺ depletion treatment in the absence or presence of KB-R7943. TTC-positive staining represents viable tissue. B. Group results on the myocardial injury area, which is expressed as a percentage of the total area. C. Group results on LDH release. Each bar represents the mean±SEM, n = 6. ^## P<0.01 vs. the control, **P<0.01 vs. CaD3, ^† P<0.01 vs. MDL+CaD3. Abbreviations: MDL+C, MDL28170 control; KBR+C, KB-R7943 control; CaD3, 3-min Ca²⁺ depletion group; MDL, MDL28170; and KBR, KB-R7943.
