Figure 3.

Typical myocardial staining of rats in each group. The blue area of Evans Blue staining is the normal area, the red part of TTC staining is ischemic myocardial tissue, and the pale part is the infarcted area. There was no obvious prominent white staining stained zone in rats of the Sham group; the white staining stained area increased in the I/R group. Compared with the I/R group, the white staining stained area decreased among the EA pretreatment group, EA pretreatment + Antagomirs group, and Antagomirs group, respectively.
