The three distinct rRIPoC procedures reduced the MPO level compared with that with RIPoC procedure at 3 days after ischemia, with 82.3 ± 12.1 μUnit/mg for every half day, 83.8 ± 12.6 μUnit/mg for every 1 day, 112.8 ± 19.1 μUnit/mg for every 2 days (P < 0.05, versus 141.0 ± 22.6 μUnit/mg). This evidence concerns the gene MPO and ischemia.
