Figure 1 Total NOS activity in gastric adenocarcinoma and normal tissues [pmole/(min·mg) protein].

Figure 2 Total NOS activity of gastric cancer by histological classification [pmole/(min·mg) protein]. Normal: normal gastric mucosa Well: well differentiated Moderate: moderately differentiated Poor: poorly differentiated.

Figure 3 Immunohistochemical strong staining for NOS in cytoplasm (SP), ×400. A: Expression of iNOS in gastric cancer cells; B: Expression of eNOS in gastric mucosal cells.

Figure 4 Expression of NOS mRNA in gastric cancer (ISH), ×400. A: Strong iNOS mRNA expression; B: Weak eNOS mRNA expression.
