Figure 5: ST+EI prevents myocaridal mitochondrial DNA deletion after CPB.

The mitochondrial DNA deletion, reflected as the 951 bp DNA segment, was observed in only one of the four tested animals (Lane 13) from group ST+EI while it was seen in all the four tested animals from group ST+EL and ST. The internal control, the 496 bp band, was seen in each tested animal from all the three groups. EI = Emulsified Isoflurane; EL = Emulsified Intralipid; ST = St. Thomas cardioplegia solution (n = 4).
