SPRR3 and myocardial infarction: Compared with SPRC, CR-SPRC significantly reduced the Cmax from 31.65±1.73 (μg/ml) to 26.10±3.68 (μg/ml) in normal rats and from 27.75±1.89 (μg/ml) to 21.02±2.37 (μg/ml) in MI model rats and it delayed the Tmax from 0.8±0.3 h to 2.7±1.0 h in normal and MI rats (Figure 7 and Table 2).
