Histological assessment of inflammatory score and of neutrophil influx in the intestine after I/R injury in Ptx3^−/− and wild-type mice. Wild-type (WT) or Ptx3^−/− mice were sham-operated (Sh) or subjected to 60 minutes of ischemia of the superior mesenteric artery followed by 30 minutes of reperfusion (I/R), then sections were graded for inflammatory score (A) or neutrophil influx (B), as described in the Materials and Methods. Neutrophil influx is shown as number of neutrophils per mm². Results are the mean ± SD of five mice in each group. *P < 0.01 when compared with sham-operated mice; ^#P < 0.01 when compared with mice subjected to I/R.
