Figure 1 Immunohistochemical demonstration of iNOS expression in cases of pancreatic adenocarcinomas with moderate (A) and strong (B) staining intensity.
There was a cytoplasmatic staining pattern with distribution within the tumor. No nuclear staining was observed. Cells of the islets of Langerhans were also positive (C). Original magnification × 200, Hematoxylin counterstaining.
Figure 2 COX-2 immunohistochemistry in pancreatic adenocarcinomas shown in a case with (A) moderate and (B) strong staining intensity.
Immunostaining was restricted to the cytoplasm. Even in the case with high staining only a portion of tumor cells expressed COX-2. Cells of the islets of Langerhans were also stained (C). Original magnification × 200, Hematoxylin counterstaining.
Figure 3 Comparison of iNOS or COX-2 expression with microvessel density.
No statistically significant correlation could be noted.
