Notes:

^**Significance level with Kruskal–Wallis test, P<0.05.

^*P<0.05 compared with Group IR. Group C is the Control Group, Group IR is the Ischemia Reperfusion Group, Group IR-A is the Ischemia Reperfusion Group treated with Alprostadil, Group IR-I is the Ischemia Reperfusion Group Treated with Iloprost.

Abbreviation: PMNL, polymorphonuclear leukocyte.
