Fig. 4.
Infarct size ratio. a Myocardium stained with 2,3,5-triphenyltetrazolium chloride(TTC) in white white emboli group. b Myocardium stained with TTC in rt-PA group. c The infarct size of rt-PA group and white emboli group are 1.1 ± 0.19 cm2 and 2.86 ± 0.18 cm2, respectively. The infarct size ratio (%) in rt-PA group was significantly smaller than it of white emboli group (4.48 ± 0.52 vs. 11.61 ± 0.64, *p < 0.01). ▇ = rt-PA group (n = 6), □ = white emboli group (n = 6) Vertical bars represent SEM
