Figure 2

Evans Blue and 2,3,5-triphenyltetrazolium chloride (TTC) double staining in each group’s rats. Evans Blue and 2,3,5-triphenyltetrazolium chloride (TTC) double staining was used to determine the ischemic size and infarction size. (a) WT rats myocardial slice stained by Evans Blue and TTC. (b) UTR knockdown rats myocardial slice stained by Evans Blue and TTC. The normal area was stained blue, the area at risk (ARR) was stained red, and the area of infract size (IS) was stained pale white. (A): sham; (B): model; (C): 5.4 mg/kg nifedipine; (D): 2.0 μg/kg SB-710411; and (E)~(G): 20, 40, and 80 mg/kg TFR.
