  • Staining intensity scores was as follows: weak=no staining and mild stain intensity, strong=moderate and strong stain intensity. We did statistical analysis using SPSS V.20.0 (IBM, Armonk, New York, USA). Statistical significance was set at p<0.05.

  • IHC, immunohistochemical stain; iNOS, inducible nitric oxide synthase.
